DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

The present invention is further described in detail below in conjunction with the accompanying drawings.

This specific embodiment is merely an explanation of the present invention, but not a limitation of the present invention. After reading this specification, those skilled in the art can make non-creative modifications to this embodiment based on a requirement, and these modifications are all protected by the Patent Law as long as they are within the scope of the claims of the present invention.

This embodiment relates to a card dealing machine, which, referring to FIGS. 1 to 4, includes: a housing 100, a card delivering mechanism 200, a card distributing mechanism 300, and a card dealing mechanism 400. For ease of description and understanding, a direction in which playing cards are dealt is taken as a front side, and the opposite direction is taken as a back side.

Referring to FIGS. 1 to 2, the housing 100 has a card bin 110 for accommodating playing cards, a card taking and placing port 120 positioned at a top side and/or a rear side of the card bin 110, a card delivering port 130 positioned at a bottom front side of the card bin 110, and a card dealing port 140 positioned at a front side of the housing 100 and corresponding to the card delivering port 130. The playing cards are placed into the card bin 110 from the card taking and placing port 120 and then are dealt from the card dealing port 140 by the card delivering port 130.

In this embodiment, a rear side (one side far away from the card delivering port 130) and a top of the card bin 110 are both open structures, forming an open card bin 110, so that the process of placing and taking cards is simpler and easier. Since the rear side of the card bin 110 is an open structure, a length of the playing cards placed in the card bin 110 can exceed a length of the card bin 110, and the card bin can be adapted to more types of playing cards. Of course, in other embodiments, the card bin 110 may also be an open structure with only the top or the back side.

Further, referring to FIG. 4, a bottom surface of the card bin 110 is an inclined surface inclined from an open side to a card delivering port 130, and the open side of the bottom surface of the card bin 110 is higher, so that the playing cards are always inclined toward the card delivering port 130 when the housing 100 rotates, and thus the playing cards are not easily thrown out when the card dealing machine rotates to deal the playing cards.

Referring to FIGS. 1 to 2, the card delivering mechanism 200 is arranged at a bottom of the card bin 110 and used to deliver playing cards in the card bin 110 to the card delivering port 130. Referring to FIG. 6, the card distributing mechanism 300 includes a lower card distributing member 320 arranged on a lower side of the card delivering port 130 and an upper card distributing member 310 rotatably arranged on an upper side of the card delivering port 130. Referring to FIG. 4, the card dealing mechanism 400 is arranged at a bottom of the card bin 110, positioned between the card distributing mechanism 300 and the card dealing port 140 and used to deliver playing cards passing through the card distributing mechanism 300 out of the card dealing port 140.

In this embodiment, only one group of card distributing mechanisms 300 are provided and arranged in a middle of the card delivering port 130, the card distributing mechanism 300 only distributes and shuffles playing cards in the middle of the card delivering port 130, and two sides of the card delivering port 130 do not limit the playing cards, so that the card distributing mechanism 300 can also distribute playing cards when facing some playing cards that are used and may be bent and deformed at left and right sides or some playing cards with narrow widths. Two sides of the card dealing machine have a large height for the bent playing cards to enter, which can effectively avoid card jamming, and improve the compatibility and adaptability of the card dealing machine and the smoothness of card distributing. Of course, in other embodiments, the card distributing assembly may be arranged at other positions of the card delivering port 130, or a plurality of card distributing assemblies are provided.

Specifically, in this embodiment, referring to FIGS. 5 to 9, the upper card distributing member 310 includes: a frame 311, a first card distributing roller 312, a second card distributing roller 313, a first guide block 314, and a second guide block 315. The frame 311 is mounted in the housing 100; the first card distributing roller 312 is rotatably assembled on a lower side of the frame 311 and corresponds to the lower card distributing member 320; the second card distributing roller 313 is rotatably assembled on a lower side of the frame 311 and positioned at a front side of the first card distributing roller 312, and has a lower surface higher than a lower surface of the first card distributing roller 312; the first guide block 314 is arranged on a lower side of the frame 311 and positioned between the first card distributing roller 312 and the second card distributing roller 313; and the second guide block 315 is arranged on a lower side of the frame 311 and positioned between the first guide block 314 and the second card distributing roller 313, and has a lower surface lower than a lower surface of the first guide block 314. In some embodiments, two guide blocks may be positioned between the axis of the first card distributing roller 312 and the axis of the second card distributing roller 313, that is, two guide blocks may be aligned with the edges of two card distributing rollers in a length direction (a card dealing direction).

The first guide block 314 is provided with a first guide inclined surface 3141 that is inclined downwards in a card dealing direction, and the second guide block 315 is provided with a second guide inclined surface 3151 that is inclined downwards towards in a card dealing direction. When the playing cards pass through the card distributing mechanism 300, the playing cards first pass between the first card distributing roller 312 and the lower card distributing member 320, driving the first card distributing roller 312 to roll, and then the playing cards successively pass through the first guide block 314 and the second guide block 315 under the guidance of the first guide inclined surface 3141 and the second guide inclined surface 3151, and then drive the second card distributing roller 313 to roll, and finally enter the card dealing mechanism 400.

The lower card distributing member 320 is arranged, and the upper card distributing member 310 includes: the first card distributing roller 312 and the second card distributing roller 313, so that playing cards in the card bin 110 driven to the card delivering port 130 by the card delivering mechanism 200 can be subjected to a first card distribution under the combined action of the lower card distributing member 320 and the first card distributing roller 312, and then subjected to a second card distribution by the second card distributing roller 313, the possibility that the playing cards are overlapped is greatly reduced by two card distributions, and a good card dealing effect and accurate card dealing quantity are ensured. The setting of the two card distributions also makes it unnecessary to be too strict in the first card distribution, increases the tolerance for playing cards of different thicknesses, and improves the adaptability of the card dealing machine. In the second card distribution, the playing cards are distributed again to ensure the card distributing effect of the card distributing mechanism 300, and one card distribution is divided into two card distributions can also improve the smoothness of the card distributing.

Two card distributions are achieved by adopting a card distributing roller capable of rolling along a card dealing direction. Due to rolling friction, a friction force between playing cards and the card distributing roller can be effectively reduced, so that the card distributing process is smoother, the card jamming is avoided, the abrasion of the card distributing process on the two card distributing rollers can be reduced, the abrasion of the playing cards is reduced, and the service lives of the card dealing machine and the playing cards are effectively prolonged.

The first guide block 314 and the second guide block 315 are arranged between the first card distributing roller 312 and the second card distributing roller 313, and the first guide inclined surface 3141 and the second guide inclined surface 3151 are respectively arranged on the first guide block 314 and the second guide block 315, so that playing cards passing through the first card distributing roller 312 can smoothly contact the second card distributing roller 313 by the first guide inclined surface 3141 and the second guide inclined surface 3151, thereby ensuring that each playing card is subjected to two card distributions; in addition, the arrangement of the first guide inclined surface 3141 can also play a role in leveling the playing cards with front ends tilted up, so that the playing cards can smoothly pass through the second guide block 315 and the second card distributing roller 313; and if only the second guide block 315 is arranged, the playing cards passing through the first card distributing roller 312 and with the front ends tilted up collide with the second guide inclined surface 3151 in a tilted posture, which may easily cause the card jamming. It should be noted that the front end of the playing card is easily tilted up after passing through the first card distributing roller 312, so that it is very necessary to provide the first guide block 314.

In this embodiment, referring to FIGS. 5 to 9, two first card distributing rollers 312 are symmetrically arranged on left and right sides of the upper card distributing member 310, and the two card distributing rollers can rotate independently, so that the playing cards can pass through more smoothly. The second card distributing roller 313 is positioned between two first card distributing rollers 312, so that the second card distributing roller 313 can smoothly contact the playing cards passing through the first card distributing rollers 312, and the card distributing mechanism 300 can achieve the effect of two card distributions.

In this embodiment, referring to FIGS. 5 to 9, one first guide block 314 is provided and positioned between two first card distributing rollers 312, and does not contact two first card distributing rollers 312. In addition, the first guide inclined surface 3141 of the first guide block 314 overlaps with an edge of the first card distributing roller 312 in a length direction (a card dealing direction), so that this arrangement saves space, has a more compact structure, and does not affect the card distributing guide effect. Two second guide blocks 315 are provided and positioned at two sides of the second card distributing roller 313, and the second guide inclined surface 3151 of the second guide block 315 does not overlap with the first guide inclined surface 3141 in a length direction (a card dealing direction), but overlaps with an edge of the second card distributing roller 313. With the arrangement of two second guide blocks 315, a contact area between the playing cards and the second guide inclined surface 3151 is larger, so that a stress balance between a left side and a right side of the playing cards is ensured, the deformation of the playing cards caused by the impact of the playing cards on the second guide inclined surface 3151 is reduced, and the playing cards can be better guided.

In this embodiment, an included angle between the first guide inclined surface 3141 and a horizontal plane and an included angle between the second guide inclined surface 3151 and a horizontal plane are both 30°, so that the two guide inclined surfaces can well achieve the playing card guide function, and ensure that the playing cards can smoothly contact the second card distributing roller 313, thereby achieving two card distributions. Of course, in other embodiments, an included angle between the first guide inclined surface 3141 and a horizontal plane and an included angle between the second guide inclined surface 3151 and a horizontal plane may be set to different angles. In addition, an included angle between the first guide inclined surface 3141 and a horizontal plane and an included angle between the second guide inclined surface 3151 and a horizontal plane may also be set to 20°, 25°, 35°, 40°, 45°, 50°, 60°, and the like.

Referring to FIGS. 5 to 9, in this embodiment, the lower card distributing member 320 includes: a lower card distributing roller 321 arranged at a lower side of the card delivering port 130 and rolling along a card dealing direction, and a card distributing shaft 350 arranged in the housing 100, used for the lower card distributing roller 321 to sleeve and used to drive the lower card distributing roller 321 to rotate. In the working process of the card dealing machine, the lower card distributing roller 321 can rotate along a card dealing direction, so that the friction force between the playing cards and the lower card distributing member 320 can be effectively reduced, the process of the playing cards passing through the lower card distributing member 320 is smoother, and good card distributing and dealing effects are ensured.

Referring to FIGS. 5 to 9, in this embodiment, a periphery of the lower card distributing roller 321 is provided with a plurality of grooves 3211 extending therethrough from left to right at intervals. With the arrangement of the grooves 3211, when there is some dust on the lower card distributing roller 321, the lower card distributing roller 321 can also roll the playing cards into the card delivering port 130 by these grooves 3211, thereby ensuring the good operation of the card distributing mechanism 300. The groove 3211 has a V-shaped cross section.

Referring to FIGS. 5 to 9, in this embodiment, the frame 311 is rotatably connected to the housing 100 at an upper front end thereof, an elastic member 330 is arranged between an upper surface of the frame 311 close to a rear end and the housing 100, the elastic member 330 presses a rear end of the frame 311 toward the lower card distributing member 320, and then the first card distributing roller 312 is pressed downward to an upper side of the lower card distributing member 320. In the process of card distribution, the first card distributing roller 312 can float upwards, and the floating arrangement of the first card distributing roller 312 can make a card distributing structure adapt to different thicknesses of playing cards. The first card distributing roller 312 can float up and down based on the thicknesses of the playing cards so as to allow different thicknesses of playing cards to pass through, and the card distributing mechanism 300 does not need to be adjusted based on the thicknesses of the playing cards, which is more convenient and labor-saving. Under the condition that the lower card distributing roller 321 has power, the first card distributing roller 312 can press the playing cards to a direction of the lower card distributing roller 321, so that the friction force between the playing cards and the lower card distributing roller 321 can be increased, the playing cards can be better driven by the lower card distributing roller 321 and can smoothly enter the card delivering port 130, and good card distributing and dealing effects can be achieved. The second card distributing roller 313 is arranged at a front end of the frame 311, and in the process that the first card distributing roller 312 floats up and down, the position change of the second card distributing roller 313 is small, so that the effect of smooth card distribution by the second card distributing roller 313 is ensured.

Referring to FIGS. 5 to 9, in this embodiment, a shock absorbing layer 340 is arranged on an upper surface of the frame 311. Since the card distributing mechanism 300 is provided with a floating structure, certain noise is generated during the up and down floating process, and the arrangement of the shock absorbing layer 340 can achieve a certain noise reduction effect. In addition, the shock absorbing effect of the shock absorbing layer 340 also increases the service life of the card distributing mechanism 300.

To facilitate the installation of the elastic member 330, a limiting groove 3111 for installing the elastic member 330 is provided on an upper surface of the frame 311. In this embodiment, the elastic member 330 is a spring. The shock absorbing layer 340 is provided with a shock absorbing ring layer 341 placed into a periphery of the limiting groove 3111. The shock absorbing ring layer 341 is placed in an inner peripheral side of the limiting groove 3111, so as to facilitate the installation of the shock absorbing layer 340, and also to prevent the shock absorbing layer 340 from falling off from the frame 311. In addition, a front end of the shock absorbing layer 340 extends downward to form an extended shock absorbing layer 342 which half wraps around a front side of the frame 311. The extended shock absorbing layer 342 prevents the front end of the frame 311 from directly contacting the inside of the housing 100, and also plays a role in shock absorption. The shock absorbing layer 340 is made of a flexible material. Specifically, in this embodiment, the shock absorbing layer 340 is made of a PET material. In other embodiments, the shock absorbing layer 340 may also be made of a silicone rubber or other soft rubber materials.

Referring to FIG. 10, in this embodiment, the first card distributing roller 312 includes: a hard inner sleeve 3121 rotatably assembled on a lower side of the frame 311, and a soft outer sleeve 3122 sleeved on an outer side of the hard inner sleeve 3121. The soft outer sleeve 3122 is arranged at the outermost side of the first card distributing roller 312, which achieves the shock absorption effect, and also protects the first card distributing roller 312, the lower card distributing roller 321 and the playing cards. In this embodiment, the hard inner sleeve 3121 is made of copper, and the soft outer sleeve 3122 is made of soft rubber. In other embodiments, the soft outer sleeve 3122 can also be made of a silicone rubber or a PET material.

Referring to FIGS. 2, 4, 11 and 12, in this embodiment, the card delivering mechanism 200 includes: a card delivering roller 210 arranged at a bottom of the card bin 110, partially exposed from the card bin 110 and used to deliver the playing cards in the card bin 110 into the card delivering port 130; and a card delivering shaft 220 arranged in the housing 100, used for the card delivering roller 210 to sleeve and used to drive the card delivering roller 210 to rotate. The card delivering roller 210 can contact the playing cards on a bottom side of the interior of the card bin 110, and the playing cards in the card bin 110 are delivered into the card delivering port 130 by the rotation of the card delivering roller 210.

Referring to FIGS. 4, 5, 11, and 12, the card dealing mechanism 400 includes: a card dealing roller 410 positioned between the card distributing mechanism 300 and the card dealing port 140 and used to deal the playing cards passing through the card distributing mechanism 300 out of the card dealing port 140; and a card dealing shaft 420 arranged in the housing 100, used for the card dealing roller 410 to sleeve and used to drive the card dealing roller 410 to rotate. The rotation of the card dealing roller 410 drives the playing cards positioned thereon to be dealt out of the card dealing port 140, which ensures a good card dealing effect and a sufficient card dealing distance.

Still referring to FIGS. 11 to 13, the card dealing machine further includes: a driving member 800, a first transmission assembly 500, a second transmission assembly 600, and a third transmission assembly 700. Specifically, in this embodiment, the driving member 800 is a driving motor.

The driving member 800 is arranged in the housing 100 and is a power portion for driving the card dealing machine to complete the entire card dealing operation. The first transmission assembly 500 is arranged in the housing 100, and has one end connected to an output end of the driving member 800 and the other end connected to the card dealing shaft 420, so as to drive the card dealing shaft 420 to rotate under driving of the driving member 800. The second transmission assembly 600 is arranged in the housing 100, and has one end connected to the other end of the card dealing shaft 420 and the other end connected to the card distributing shaft 350, so as to drive the card distributing shaft 350 to rotate. The third transmission assembly 700 is arranged in the housing 100, and has one end connected to the second transmission assembly 600 and the other end connected to the card delivering shaft 220, so as to drive the card delivering shaft 220 to rotate. With the power transmission of the first transmission assembly 500, the second transmission assembly 600 and the third transmission assembly 700, the card dealing machine can drive the rotation of the lower card distributing roller 321, the card delivering roller 210 and the card dealing roller 410 by only one driving member 800, so as to deal the playing cards out of the card bin 110. When the card dealing machine is started or stopped, the lower card distributing roller 321, the card delivering roller 210 and the card dealing roller 410 can be started or stopped at the same time, and the use experience of the card dealing machine is improved. Meanwhile, only one driving member 800 is arranged, so that the production cost of the card dealing machine can be effectively reduced, and the size of the card dealing machine is reduced.

Referring to FIGS. 11 to 13, in this embodiment, the second transmission assembly 600 includes: a card dealing gear 610, a card distributing gear 650, a first gear 630, a second gear 620, and a third gear 640. Specifically, the card dealing gear 610 is sleeved on the card dealing shaft 420; the card distributing gear 650 is sleeved on the card distributing shaft 350; the second gear 620 is engaged between the card dealing gear 610 and the first gear 630, and the third gear 640 is engaged between the card distributing gear 650 and the first gear 630.

The first gear 630 is arranged above the card dealing gear 610, the second gear 620 is arranged between the first gear 630 and the card dealing gear 610, and the axis of the second gear 620 is positioned at one side of a center line connecting the card dealing gear 610 and the first gear 630 positioned at the card dealing port 140. With the specific arrangement of these gears, when the card dealing gear 610, the second gear 620 and the first gear 630 rotate, the card dealing gear 610 and the first gear 630 can provide an acting force towards the card dealing direction for the second gear 620, so that it is possible to prevent the second gear 620 from being clamped between the first gear 630 and the card dealing gear 610, which causes the second gear 620 to get struck with the card dealing gear 610 and the first gear 630, and affects the card dealing smoothness and the card dealing distance of the card dealing machine.

The card distributing gear 650 is arranged below the first gear 630, the third gear 640 is arranged between the first gear 630 and the card distributing gear 650, and the axis of the third gear 640 is positioned on one side of a center line connecting the card distributing gear 650 and the first gear 630 far away from the card dealing port 140. With the specific arrangement of these gears, when the first gear 630, the third gear 640 and the card distributing gear 650 rotate, the first gear 630 and the card distributing gear 650 can provide an acting force to the third gear 640 in a direction opposite to a card dealing direction, so that it is possible to prevent the third gear 640 from being clamped between the first gear 630 and the card distributing gear 650, which causes the third gear 640 to get stuck with the first gear 630 and the card distributing gear 650, and affects the card dealing smoothness and the card dealing distance of the card dealing machine.

In this embodiment, referring to FIG. 13, an included angle between a center line connecting the second gear 620 and the card dealing gear 610 and a center line connecting the first gear 630 and the card dealing gear 610 is 27°. Therefore, the second gear 620 achieves good and smooth transmission and achieves a good card dealing effect. Of course, in other embodiments, an included angle between a center line connecting the second gear 620 and the card dealing gear 610 and a center line connecting the first gear 630 and the card dealing gear 610 may also be 20°, 21°, 22°, 23°, 24°, 25°, 26°, 28°, 29°, 30°, and the like.

In this embodiment, still referring to FIG. 13, an included angle between a center line connecting the third gear 640 and the card dealing gear 650 and a center line connecting the first gear 630 and the card dealing gear 650 is 31°. Therefore, the third gear 640 can achieve a good and smooth transmission effect, avoid the occurrence of stuck gear, and improve the user experience of the card dealing machine. Of course, in other embodiments, an included angle between a center line connecting the third gear 640 and the card dealing gear 650 and a center line connecting the first gear 630 and the card dealing gear 650 may also be 25°, 26°, 27°, 28°, 29°, 30°, 32°, 33°, 34°, 35°, and the like.

In this embodiment, referring to FIGS. 11 to 12, the first transmission assembly 500 includes: a driving pulley 510 sleeved on an output shaft of the driving member 800, a card dealing pulley 530 arranged on the card dealing shaft 420, and a first belt 520 connecting the driving pulley 510 and the card dealing pulley 530. The output shaft of the driving member 800 drives the driving pulley 510 to rotate, and the driving pulley 510 drives the card dealing pulley 530 sleeved on the card dealing shaft 420 to rotate by the first belt 520, so that the card dealing shaft 420 is driven to rotate, the card dealing roller 410 rotates to achieve a good dealing effect, and the transmission stability and reliability are ensured. Of course, in other embodiments, the first transmission assembly 500 may also be configured as other structures to achieve power transmission from the driving member 800 to the card dealing shaft 420. In a preferred embodiment, the card dealing gear 610 and the card dealing pulley 530 are respectively arranged at two ends of the card dealing shaft 420, which not only can avoid mutual interference between the first transmission assembly 500 and the second transmission assembly 600, but also can balance the forces applied to the two ends of the card dealing shaft 420, thereby ensuring stable operation of the card dealing machine.

The third transmission assembly 700 specifically includes: a card delivering pulley 710 sleeved on the card delivering shaft 220, a transmission pulley 720 arranged outside the first gear 630 and rotating simultaneously with the first gear 630 around the same rotation axis, and a third belt 730 connecting the card delivering pulley 710 and the transmission pulley 720.

Referring to FIG. 13, a diameter of the first gear 630 is greater than that of the second gear 620, and a diameter of the second gear 620 is greater than that of the card dealing gear 610, so that the card dealing gear 610 can achieve a certain deceleration effect while transmitting power to the first gear 630. A diameter of the second gear 620 is the same as that of the third gear 640, so that the second gear 620 and the third gear 640 are balanced in the second transmission assembly 600, and a stable transmission effect is achieved. A diameter of the card distributing gear 650 is greater than that of the card dealing gear 610, so that under the action of the second transmission assembly 600, a rotating speed of the card distributing gear 650 is lower than that of the card dealing gear 610, that is, a rotating speed of the lower card distributing roller 321 is lower than that of the card dealing roller 410, and a good card dealing effect is achieved.

Based on this, a one-way bearing 900 is arranged between the card distributing gear 650 and the card distributing shaft 350, and the one-way bearing 900 is used to achieve power transmission and disconnection between the card distributing gear 650 and the card distributing shaft 350. The one-way bearing 900 belongs to the prior art, an outer ring of the one-way bearing 900 is connected to the card dealing gear 650, and an inner ring of the one-way bearing 900 is connected to the card distributing shaft 350. When the rotation of the lower card distributing roller 321 is required for card distribution, the card distributing gear 650 applies an acting force to the one-way bearing 900, in this case, the rotating speed of the outer ring of the one-way bearing 900 exceeds that of the inner ring, the inner ring and the outer ring of the one-way bearing 900 are combined, and the outer ring drives the inner ring to rotate, so that the power of the card distributing gear 650 is transmitted to the card dealing shaft 420, the lower card distributing roller 321 is driven to rotate, and the playing cards on the lower card distributing roller 321 are distributed. When the lower card distributing roller 321 delivers the playing cards forwards, the card dealing roller 410 contacts the front side of the playing cards, since the rotating speed of the card dealing roller 410 is greater than that of the lower card distributing roller 321, the card dealing roller 410 drives the lower card distributing roller 321 to rotate by the playing cards, and the lower card distributing roller 321 drives the card distributing shaft 350 to rotate, so that the rotating speed of the card distributing shaft 350 is greater than that of the card distributing gear 650. Since the one-way transmission characteristic of the one-way bearing 900, the inner ring and the outer ring of the one-way bearing 900 are separated and independently rotate, and the rotating speed of the inner ring of the one-way bearing 900 is greater than that of the outer ring, so that the power of the card distributing gear 650 cannot be transmitted to the card distributing shaft 350 through the one-way bearing 900, the lower card distributing roller 321 cannot be decelerated under the action of the second transmission assembly 600, and smooth card distributing and card dealing effects can be better achieved.
