DETAILED DESCRIPTION OF THE EMBODIMENTS

The preferred embodiment of the disclosure will be further illustrated in detail with reference to the accompanying drawings.

The embodiments of the disclosure are illustrated in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments illustrated below with reference to the accompanying drawings are exemplary and intended to illustrate the disclosure, and should not be construed as limitations to the disclosure.

As shown in FIG. 1 to FIG. 5, a shuffling machine of one embodiment of the disclosure is disclosed. The shuffling machine includes a housing base 12, and a card receiving compartment 11 is arranged inside the housing base 12. Specifically, the housing base 12 includes a housing body 100, as well as a cover body 200 and card bearing plates 22 respectively fixed on the top of the housing body 100. In the embodiment, the card card receiving compartment 11 is arranged inside the housing body 100, the card receiving compartment 11 is formed by the housing base 12 as a whole, openings is formed on the upper side, lower side, and front side of the card receiving compartment 11, and the opening on upper side of the card receiving compartment 11 is in communication with the shuffling port 23, namely, a card compartment opening 102 in communication with the card receiving compartment 11 and the outside is formed on the housing body 100, and extends from the bottom wall of the housing body 100 to the side wall of the housing body 100. The cover body 200 is located directly above the card receiving compartment 11, and the card bearing plate 22 is located outside the card receiving compartment 11. Two shuffling ports 23 are formed opposite each other between the cover body 200 and the card bearing plate 22, and the shuffling ports 23 are in communication with the card receiving compartment 11.

Meanwhile, two sets of shuffling mechanisms 2 are arranged on the housing base 12 and at the top of the card receiving compartment 11 to push the cards to fall into the card receiving compartment 11 in a staggered manner, and the two sets of shuffling mechanisms 2 are arranged opposite to each other. A control circuit board 7 (as shown in FIG. 3, the control circuit board 7 is located inside the cover body 200) is further arranged inside the housing base 12. The control circuit board 7 is electrically connected to the shuffling mechanisms 2, and the top of the housing base 12 (as shown in FIG. 3, specifically on the outer surface of the cover body 200) is correspondingly provided with two buttons 8 which are in contact with two touch switches on the control circuit board 7, so that the on-off and shuffling operations of the shuffler are controlled by the buttons 8. Specifically, the two touch switches are a self-locking switch and a self-resetting switch, both of which can control the start and stop of the shuffling mechanisms 2, allowing users to adjust the shuffling mode according to different needs. The control circuit board 7 is electrically connected with a charging interface 9, which is used to charge the battery (not shown in the figure) arranged inside the housing base 12. In addition, ordinary battery replacement can also be used, so there is no need to provide a charging interface 9.

Two card bearing plates 22 connected with the housing body 100 by screws or buckles are oppositely arranged at the top of the card receiving compartment 11, and the housing body 100 is respectively provided with a shuffling port 23 corresponding to the inner side of each of the card bearing plates 22. Specifically, two shuffling ports 23 are symmetrically arranged on the left side and right side of the card receiving compartment 11. A set of shuffling mechanism 2 is mounted at the position corresponding to each shuffling port 23 on the card bearing plate 22. Each set of the shuffling mechanism 2 is covered with a card bearing plate 22, and each card bearing plate 22 is inclined from outside to inside and from top to bottom, that is, higher in the outer side and lower in the inner side, so that the cards placed on the card bearing plate 22 can slide towards the shuffling port 23 stably and smoothly from high angle to low angle without scattering outward. Meanwhile, limiting stop blocks 222 are further arranged on the outer side of each card bearing plate 22 away from the shuffling port 23. The limiting stop blocks 222 can support and hold the cards placed on the card bearing plate 22, thereby reducing the friction between the cards and the surface of the card bearing plate 22 and making the card pushing smoother. Moreover, each card bearing plate 22 is further provided with a raised strip 223, which extends from the inner side to the outer side of the card bearing plate 22. The height of the raised strip 223 is smaller than that of the shuffling conveyor wheel 24 in the shuffling mechanism 2, which can also play a role in supporting and holding cards, reducing the friction between the cards and the surface of the card bearing plate 22, and making the pushing of the cards smoother.

In the embodiment, the outer side of the cover body 200 is fixed with a side baffle 400, and the card bearing plate 22 is fixed to the cover body 200 as a whole through the side baffle 400. Specifically, the cover body 200 is integrally fixed with one of the side baffles 400, and the two sides of the side baffle 400 are integrally and fixedly connected to two card bearing plates 22, so that the cover body 200 can be integrally fixed with the card bearing plates 22. Moreover, the card bearing plate 22 and the side baffle 400 are detachably connected to the top of the housing body 100 through a screw or a snap fastener, which facilitates the manufacturing and installation of the housing base 12, improves the installation efficiency of various components of the shuffling machine, and facilitates the maintenance of each component.

In the embodiment, each set of shuffling mechanisms 2 includes a shuffling conveyor wheel 24. The shuffling conveyor wheel 24 is arranged at the middle position of the shuffling port 23, and a rotary shuffling restriction mechanism 5 is arranged above the shuffling conveyor wheel 24. Specifically, the rotary shuffling restriction mechanism 5 includes a mounting base 51, a connecting shaft 52 arranged on the mounting base 51, and a card restriction wheel 53 sleeved on the connecting shaft 52. The inner diameter of the card restriction wheel 53 is slightly larger than the outer diameter of the connecting shaft 52, so that the card restriction wheel 53 can rotate and move up and down on the connecting shaft 52. The mounting base 51 is fixed to the cover body 200 by screws. At this time, a slot opening 121 is formed on the position of the cover body 200 corresponding to the mounting base 51, and the card restriction wheel 53 is rotatably arranged in the slot opening 121. As a card restriction wheel 53 is arranged above the shuffling conveyor wheel 24 to be used in conjunction with the shuffling conveyor wheel 24, a limiting gap effect is formed between the rotatable card restriction wheel 53 and the shuffling conveyor wheel 24, therefore the limiting of card passing space is achieved during shuffling, the cards are always in full contact with the shuffling conveyor wheel 24 without sticking and slipping. Meanwhile the cards passing number is limited during shuffling, achieving card shuffling one by one as possible, avoiding the problem of adhesive stacking of shuffled cards entering the shuffling port 23, effectively improving the smoothness of shuffling, and making each shuffling more uniform and thorough. As the card restriction wheel 53 is correspondingly arranged at the middle upper of the shuffling port 23, there is enough space left at both ends of the card restriction wheel 53, therefore a curved card can be smoothly and accurately transferred into the shuffling port 23, avoiding the problem of card jamming during the shuffling process. In addition,, as the card restriction wheel 53 can move up and down a certain distance, thereby realizing the conveying of cards with different thicknesses by the card restriction wheel 53, greatly improving applicability of the shuffling machine and meeting the needs of card players.

In the embodiment, the two sets of the shuffling mechanisms 2 are driven to rotate synchronously by a unified power mechanism. Specifically, the two sets of the shuffling mechanisms 2 are driven by the same motor 27, and the control circuit board 7 is electrically connected to the shuffling mechanisms 2, that is, electrically connected to the motor 27. Specifically, the two sets of shuffling mechanisms 2 are respectively in transmission connection with the power output gear of the motor 27 through a set of transmission gears 28, wherein the motor 27 is mounted and fixed on the cover body 200, and each transmission gear 28 is rotatably connected to a box and mounted on the housing base 12 through the box (as shown in FIG. 3, the box is specifically mounted in one of the side baffles 400). Moreover, the two sets of the shuffling mechanisms 2 are arranged at two opposite angles in the direction of rotation, so that when the motor 27 drives the shuffling mechanisms 2 to rotate synchronously, the cards placed on the two card bearing plates 22 are staggered and fall into the card receiving compartment 11 through the shuffling port 23 to complete shuffling. As the use of the same motor 27 for shuffling, the speed consistency of shuffling on both sides can be achieved, resulting in more uniform shuffling and better shuffling effect. In addition, hand-operated manner can further be adopted, that is, a rocker connected to the transmission gear 28 is provided. The power output gear of the rocker is connected to two sets of transmission gears 28, and the synchronous rotation of the two sets of shuffling mechanisms 2 is achieved through the shaking of the rocker. The control circuit board 7 need not be provided at this time.

In order to take out the shuffled cards conveniently and quickly, a card supporting plate 6 is mounted at the bottom of the card receiving compartment 11, and the card supporting plate 6 is connected to the housing body 100 in a push-pull manner. Specifically, two sliding grooves 122 are arranged at the bottom of the shell 100 in a left-right symmetry, and the card supporting plate 6 is slidably inserted between the two sliding grooves 122. Moreover, in the embodiment, the card supporting plate 6 is of an L-shaped structure, and the long side of the L-shaped structure is connected to the sliding groove 122, which is used to seal off the opening of the lower side of the card receiving compartment 11. The short side of the L-shaped structure covers the opening of front side of the card receiving compartment 11, that is, the card supporting plate 6 can be adaptively connected in the card compartment opening 102. And the upper part of the card supporting plate 6 is of an arc-shaped structure that shrinks inward from both sides, thereby facilitating the pull-out operation of the card supporting plate 6. Meanwhile, a plurality of raised lines 61 are arranged on the card supporting plate 6. Specifically, the raised lines 61 are arranged on the inner surface of the card supporting plate 6 and located in the opening of the lower side of the card receiving compartment 11, therefore a gap is formed between the cards and the inner surface of the card supporting plate 6, and the bottom card will not adhere to the inner surface of the card supporting plate 6, ensuring smooth card retrieval.

The outer side of the cover body 200 is fixedly provided with two side baffles 400, which are arranged opposite to each other on both sides of the two card bearing plates 22. One of the side baffles 400 is arranged as a card plate adjustment limiting mechanism 3. That is to say, the housing base 12 is provided with a card plate adjustment limiting mechanism 3 that is horizontally placed on the front side of the two card bearing plates 22. By the card plate adjustment limiting mechanism 3, the cards on the card bearing plate 22 can be positioned to prevent them from scattering laterally, and the usage distance formed by the card bearing plate 22 in the length direction of the cards can be adjusted, making it suitable for shuffling operations of cards with different lengths, such as conventional cards and internationally used cards. In addition, an electric adjustment limiting mechanism can further be provided to adjust the length and space of the cards.

Specifically, when one of the side baffles 400 is arranged as the card adjustment limiting mechanism 3, the card adjustment limiting mechanism 3 includes a positioning baffle 31, a fixed connecting rod 32 fixedly connected to the positioning baffle 31, and a limiting clamping plate 33 detachably connected to the fixed connecting rod 32. A plurality of fixed connecting rods 32 are provided, and evenly divided into two sets and arranged in a bilateral symmetry manner. In the embodiment, four fixed connecting rods 32 are provided, and each fixed connecting rod 32 is a square rod. The two fixed connecting rods 32 located on the same side are arranged one above the other. The case 12 is provided with connecting holes for the fixed connecting rod 32 to pass through (as shown in FIG. 3, the connection holes are specifically distributed on the card bearing plate 22 and the cover body 200). Clamping slots 331 with downward openings are formed in the limiting clamping plate 33, and the number of clamping slots 331 is the same as the number of fixed connecting rods 32 and the positions are corresponding, that is, one card slot 331 can be clamped onto one fixed connecting rod 32. When the limiting clamping plate 33 is clamped on the fixed connecting rod 32 at the inner side of the positioning baffle 31, cards with shorter length can be placed on the card bearing plate 22; when the limiting clamping plate 33 is removed, cards with longer length can be placed on the card bearing plate 22. By the limiting clamping plate 33, the adjustment of the placing length of cards on the card bearing plate 22 can be realized more quickly, and the adjustment is convenient and accurate.

As shown in FIG. 6 to FIG. 9, another embodiment of the shuffling machine of the disclosure is disclosed. In addition to the structure shown in FIG. 1 to FIG. 5, the shuffling machine further includes a sealing cover plate 150. The housing body 100 is provided with a fixed groove 103 at a position corresponding to the bottom wall of the card receiving compartment 11, and the sealing cover plate 150 is detachably connected inside the fixed groove 103, wherein one side of the sealing cover plate 150 is provided with a protruding part, and the other side of the sealing cover plate 150 is provided with a U-shaped elastic insertion plate. The sealing cover plate 150 can be tightly fixed in the fixing groove 103 through the protruding part and the U-shaped elastic insertion plate. That is to say, the sealing cover plate 150 is detachably connected to the fixed groove 103 in an insert connection manner. The sealing cover plate 150 is used to limit the card supporting plate 6, so as to avoid the card supporting plate 6 from detaching from the bottom of the card compartment opening 102. Obviously, other methods can be used to achieve detachable connection between the fixed groove 103 and the sealing cover plate 150, such as sliding insertion, snap connection, magnetic suction connection.

As shown in FIG. 7 and FIG. 9, both the cover body 200 and the card bearing plate 22 are provided with sensing elements 10 that are electrically connected to the control circuit board 7, wherein the sensing element 10 on the cover body 200 is located on the side of the cover body 200 facing the card receiving compartment 11, and the sensing element 10 on the card bearing plate 22 is located on the side of the card bearing plate 22 where the cards are placed. Specifically, the sensing element 10 can be selected as at least one of infrared sensor, Hall sensor, ultrasonic sensor, and capacitive proximity sensor. The sensing element 10 on the cover body 200 can be used to sense whether the cards have completely fallen into the card receiving compartment 11, and can further be used to notify the control circuit board 7 to stop the operation of the shuffling mechanism 2 when no cards have fallen into the card receiving compartment 11, without the need for user operation, making the operation of the shuffling machine more intelligent. The sensing element 10 on the card bearing plate 22 can sense the situation of the cards on the card bearing plate 22, thereby achieving functions such as detecting the number of cards falling into the card receiving compartment 11, stopping when the cards reaching a limited number. Of course, the sensing element 10 can be only arranged on the cover body 200 or the card bearing plate 22.

In the embodiment, the cover body 200, the card bearing plate 22, and the side baffle 400 enclose to form two open accommodating cavity 502. Each accommodating cavity 502 is in communicated with the card receiving compartment 11 through the shuffling port 23, so that the cards to be shuffled in the accommodating cavity 502 can be sent into the card receiving compartment 11 through the shuffling port 23. A height increasing frame body 700 is detachably connected to the cover body 200. The height increasing frame body 700 includes a main body 710 that can be joined to the side wall of the cover body 200, and a side wing plate 720 that extends outward along the main body 710. The side wing plate 720 is correspondingly joined to the side baffle 400. When the height increasing frame body 700 is connected to the cover body 200, the side wall of the accommodating cavity 502 is joined to the main body 710 and the side wing plate 720 to achieve height increase, thereby increasing the capacity of the accommodating cavity 502 to accommodate more cards, reducing the number of times the user places cards, and making the shuffling operation more convenient. The side of the main body 710 corresponding to the button 8 is hollowed out to facilitate user operation of the button 8. In the embodiment, the height increasing frame body 700 further includes a clamping block 730 extending outward along the main body 710. The clamping block 730 can be inserted and connected between the cover body 200 and the side baffle 400, and is provided with an insertion block 731 that can be clamped and connected between any two connecting rods (the connecting rod in the embodiment is a fixed connecting rod 32). Thus, the height increasing frame body 700 can be detachably and fixedly joined to the cover body 200 through the structure of the clamping block 730 and the insertion block 731. Obviously, the height increasing frame body 700 can be detachably connected to the cover body 200 through other means, such as by providing magnetic attraction structures, buckle structures, plug-in structures, threaded fixing structures and the like between the height increasing frame body 700 and the cover body 200. A insertion groove can be further arranged on the clamping block 730, which can be clamped and connected to any fixed connecting rod 32, thereby further fixing the clamping block 730 to the fixed connecting rod 32.

In this embodiment, the height increasing frame body 700 further includes a folding plate 740 hinged to the main body 710. The folding plate 740 is provided with a first groove 741 that can accommodate the clamping block 730 and a second groove 742 that can be inserted into the fixed connecting rod 32. The folding plate 740 is capable of being rotated and extended into the accommodating cavity 502 or being rotated and inserted between the cover body 200 and the side baffle 400. It can be understood that the folding plate 740 plays a role in adjusting the width of the accommodating cavity 502, users can adjust the the accommodating cavity 502 by folding or unfolding the folding plate 740, so that the accommodating cavity 502 can accommodate cards of different lengths. Obviously, the folding plate 740 may not be provided in the height increasing frame body 700.

When it is necessary to increase the height of the accommodating cavity 502, the two folding plates 740 are respectively rotated, so as to be connected to the clamping block 730 through the first grooves 741, and then the clamping block 730 and the folding plate 740 are inserted between the cover body 200 and the side baffle 400, so that the second grooves 742 are inserted into the fixed connecting rods 32 one by one, so that the height increasing frame body 700 can be fixedly connected to the cover body 200. The main body 710 is connected to the side wall of the cover body 200, and the two side wing plates 720 are respectively connected to the two side baffles 400 for increasing the height of the side wall of the accommodating cavity 502. When it is necessary to adjust the width of the accommodating cavity 502, the two folding plates 740 can be rotated separately to unfold in the same direction as the side wing plate 720, followed by inserting the clamping block 730 between the cover body 200 and the first side baffle 410, and the insertion block 731 is inserted between the two fixed connecting rods 32 to achieve fixation.

If the card shuffler is not provided with the card supporting plate 6, it can selected the manner that the side baffle 400 is connected to a gear seat 413 and a stop bar 412, or an elastic claw 415 and a stop bar 412 are connected to the side baffle 400, so that the cards in the card receiving compartment 11 are unable to be separated from the card receiving compartment 11. As shown in FIG. 10, one of the side baffles 400 is arranged adjacent to the card compartment opening 102 and provided with a gear seat 413 and a stop bar 412. Specifically, a stop bar 412 is rotatably connected to the side baffle 400, and a gear seat 413 is further mounted on the side baffle 400. The gear seat 413 is movably connected to the side baffle 400 through an elastic member 414 (such as a spring). The stop bar 412 is coaxially and rotatably connected to the gear seat 413, and a plurality of engaging gear teeth 4100 are circumferentially arranged on the end faces where the stop bar 412 and the gear seat 413 are connected, and the engaging gear teeth 4100 between the stop bar 412 and the gear seat 413 are engaged and fixed under the push of the elastic member 414, so that the stop bar 412 can be rotatably positioned and transversely arranged on the card compartment opening 102. When it is necessary to adjust the swing direction of the stop bar 412 in the card compartment opening 102, the stop bar 412 is rotated, and the gear seat 413 moves and resets under the cooperative action of the stop bar 412 and the elastic member 414, so that the engaging gear teeth 4100 between the stop bar 412 and the gear seat 413 are always locked and fixed, thus realizing the rotational positioning. As shown in FIG. 11, when one of the side baffles 400 is provided with an elastic claw 415 and a stop bar 412, that is, when the gear seat 413 is replaced with an elastic claw 415, the elastic claw 415 is fixed on the side baffle 400, the stop bar 412 is adjacent to the elastic claw 415, and a plurality of clamping gear teeth 4121 are circumferentially arranged at the connecting end of the stop bar 412, and each clamping gear teeth 4121 can be locked and fixed with the elastic claw 415 when rotating, so as to realize the positioning connection between them, so that the stop bar 412 can be rotatably positioned and transversely arranged on the card compartment opening 102.
