Description

Technical Field

[0001] The invention belongs to the field of mahjong machine manufacturing, and in particular relates to a mahjong machine and a horizontal push card loading device thereof. Background Art

[0002] Mahjong is widely loved by the people as a leisure and entertainment tool, and is listed as a sports competition. The square mahjong tiles of traditional mahjong machines are parallel to the edges of the table after they are raised to the table, and the mahjong tiles are very close to the edge of the table, and the position is unreasonable. Before drawing the tiles, the players need to manually move the mahjong tiles forward and place them diagonally to the appropriate position. In the process of moving the mahjong tiles, the mahjong tiles are easy to fall over, which brings inconvenience to the players.

[0003] Patent documents with publication numbers CN109381855A, CN109794059A and CN112023390A disclose a windmill-shaped mahjong machine, in which a flat-push card loading device is arranged to be tilted relative to the side edge of the table top board on the same side, and the card inlet end of the flat-push card loading device is closer to the inside than the other end thereof, and the mahjong tiles on the four sides of the mahjong machine are lifted onto the table top of the mahjong machine at one time in the form of being tilted to the four edges of the table top board of the mahjong machine and close to the center of the table top board of the mahjong machine. By placing the flat-push card loading device at an angle, the corresponding card loading port and the side edge of the table top board on the same side of the supporting plate are also tilted, and when the mahjong tile wall rises to the table top board, it is already in a tilted state, thus eliminating the process of manually pushing tiles by the player, which is in line with the player's playing habits, and since the mahjong tile wall is pushed onto the supporting plate in a flat-push manner and then raised to the table top board by the supporting plate, there is no problem of falling tiles. However, compared with the common four-mouth mahjong machine (the flat-push card loading device is arranged parallel to the side of the table top on the same side), the flat-push card loading device is arranged at an angle, and its card inlet end is closer to the center of the mahjong machine table top, which will affect the setting of the shuffling plate and occupy the shuffling space. In order to increase the size of the shuffling plate so as to play mahjong tiles of larger sizes, a part of the card supporting plate of the flat-push card loading device is generally arranged above the card delivery device. This results in a large height difference between the card outlet height of the card delivery device and the card supporting plate when it descends to the lowest position, resulting in a large lifting span of the card bearing block in the card pushing device, low efficiency of stacking and pushing cards, unstable operation, and easy confusion of mahjong cards.

[0004] Patent documents such as publication number CN109381855A disclose a mahjong machine. In order to avoid the guide sliding shaft of the inner side end of the card lifting plate (card supporting plate) from occupying the shuffling space, the sliding shaft of the inner side end of the card lifting plate is cancelled, and the inner side end of the card lifting plate is fixedly connected to another adjacent card lifting plate through a fixing plate, so that the four card lifting plates are connected as a whole and synchronously lifted and lowered. However, because the four card lifting plates are connected as a whole and the volume is large, and the lifting and lowering synchronization of the card lifting plates driven by four card loading motors is difficult, the action stability of the card loading mechanism is poor, and it is easy to get stuck and damaged; in addition, the shuffling plate is still blocked by the card receiving device (card receiving plate and the lattice plate below it) and cannot be increased in size. And also due to the layout limitation, the height difference between the card outlet height of the card feeding device and the height difference between the card lifting plate descending to the lowest position is large, the lifting span of the card receiving seat in the stacking and pushing mechanism is too large, the stacking and pushing efficiency is low, the operation is unstable, and the mahjong cards are easily confused.

[0005] Patent documents with publication number CN109794059A and others disclose an automatic mahjong machine, in which a gap is provided between the bottom of a horizontal push card lifting device and the bottom plate for making way for a shuffling plate, so that the shuffling plate can be inserted into the gap, and the diameter of the shuffling plate is no longer restricted by the interference of the horizontal push card lifting device. Among them, one end of the horizontal push card lifting device away from the center of the shuffling plate is fixed to the bottom plate, and the rest of the horizontal push card lifting device is suspended relative to the shuffling plate, and a rocker arm connecting rod is used instead of a gear mechanism to realize transmission, so as to increase the hollow height of the bottom of the horizontal push card lifting device and increase the shuffling gap. However, the bottom is partially hollowed out and the connecting rod mechanism and hinge point are all set just below the card raising plate, which results in the bottom hollowing height of the horizontal push card loading device being relatively limited, and the actual increase in the shuffling space is not much. The horizontal push card loading device is set above the card feeding device, which not only still increases the thickness of the entire mahjong machine, but also causes a large height difference between the height of the card outlet of the card feeding device and the height of the card raising plate when it is lowered to the lowest position, resulting in a large lifting span of the card bearing block in the card pushing device (at least the thickness of three mahjong tiles), low efficiency of stacking and pushing cards, unstable operation, and easy confusion of mahjong cards. In addition, setting the stacking and pushing device in the shuffling plate or above the edge of the shuffling plate will also increase the overall thickness of the mahjong machine and occupy the shuffling space. The different transmission levels and transmission lengths of the two card raising rocker arms are also prone to asynchronous or unstable operation.

[0006] Patent documents with publication numbers CN112023387A and CN112023390A disclose a mahjong machine and a horizontal push card loading device thereof, wherein the card receiving plate is also driven to rise and fall by a horizontal push card loading motor. In this way, the shuffling plate is also restricted by the card receiving plate and the lattice plate and the lifting mechanism below it and cannot be increased in size.

[0007] Therefore, the flat push card loading windmill-shaped mahjong machine disclosed in the above patent document has a square card wall tilted in a windmill shape that is further outward than the square card wall of the slope card loading windmill-shaped mahjong machine. Generally, players still need to manually push the mahjong card wall a little further in order to play cards, which still causes inconvenience to players. The main reason is that the flat push card loading device and the shuffling plate and the card feeding device at the edge of the shuffling plate interfere with each other, resulting in the flat push card loading device and the card supporting plate for raising the cards being unable to be pushed further inward, otherwise the shuffling space will be excessively occupied, and the maximum size of mahjong tiles used in the mahjong machine will be greatly reduced.

[0008] To this end, patent documents such as publication numbers CN117982870A, CN117982871A, and CN117982868A disclose a mahjong machine and a flat push card loading device thereof, such as Figure 1 As shown, the dotted line indicates a push-up card loading device. The mahjong machine includes a shuffling plate 2 located in the center of the bottom plate of the frame, and four sets of card picking and transporting systems are arranged around the shuffling plate 2. The card picking and transporting system includes a card feeding device 5, a push-up card loading device and a card pushing device; the push-up card loading device includes a card receiving plate 72, a card supporting plate 74 and a card pushing plate 73. The card supporting plate 74 is located on the inner side of the card receiving plate 72, and the card pushing plate 73 is located on the outer side of the card receiving plate 72 and pushes the cards from the outside to the inside. One end of the card receiving plate 72 extending along the length direction is a card inlet, and a card receiving block 62 of the card pushing device is arranged outside the card inlet. The push-up card loading motor 71 drives the card pushing plate 73 to translate and push the cards and the card supporting plate 74 to lift and lower the cards; the card supporting plates 74 are respectively inclined relative to the side edges of the desktop plate, and the four sides adopt independent push-up card loading. By partially or completely hollowing out the inner side wall of the card loading seat of the flat push card loading device close to the shuffling plate, the edge of the shuffling plate can be expanded to the right below the card receiving plate, and the card feeding motor of the card feeding device can also be extended to the right below the card receiving plate. In this way, most of the card supporting plate and a small part of the card receiving plate are located above the shuffling frame, which can not only effectively increase the shuffling space while increasing the size of the shuffling plate, but also shorten the length of the card feeding channel of the card feeding device, so that the position setting of the card receiving block of the push card device and the card inlet of the flat push card loading device is more reasonable, reducing the interference and restriction of the flat push card loading device and the card feeding device on the shuffling plate and the shuffling space, so that the shuffling frame and the shuffling plate can be maximized. On the same size of the mahjong machine bottom plate, without increasing the thickness of the mahjong machine, the shuffling plate and the shuffling space are increased, for example, 108 pieces of 62 mahjong can be shuffled on a 36-table mahjong machine. However, among the four card-loading openings on the table top of the mahjong machine, the distance between two opposite card-loading openings is still relatively large, especially when playing big cards, the space for the four players is slightly insufficient, which affects the user experience. Summary of the invention

[0009] In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a mahjong machine and a flat-push card loading device thereof, which can further push the position of the card supporting plate inward without changing the overall layout of the mahjong machine, so that the spacing between the card openings on the mahjong machine table can be further reduced.

[0010] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0011] A horizontal push card loading device for a mahjong machine comprises a card receiving plate for receiving and arranging mahjong tiles of multiple piles, a card supporting plate for delivering the mahjong tiles of multiple piles to a table at one time, and a card pushing plate for pushing the mahjong tiles of multiple piles on the card receiving plate onto the card supporting plate, wherein a card storage channel for storing the mahjong tiles of multiple piles is formed on the card receiving plate, the card supporting plate is located on the inner side of the card receiving plate and can be lifted up and down, and the card pushing plate is located on the outer side of the card receiving plate and pushes the tiles from the outside to the inside; there is a gap between the card receiving plate and the card supporting plate, the width of the gap is less than one third of the length of the mahjong tiles, and when the card supporting plate is lowered to the bottom, the card supporting plane height of the top of the card supporting plate is not higher than the card storage plane height of the card receiving plate.

[0012] Preferably, the width of the gap is 3 to 15 mm, and the height difference between the card supporting plane at the top of the card supporting plate and the card storing plane of the card receiving plate is 0.5 to 1.5 mm.

[0013] Preferably, a transition plate is provided between the card-bearing plate and the card-supporting plate, and when the card-pushing plate pushes cards, multiple piles of mahjong tiles on the card-bearing plate are pushed to the card-supporting plate via the transition plate.

[0014] Preferably, the inner card loading guide shaft of the card supporting plate is arranged above the inner side of the outer circumference of the shuffling plate, the inner card loading guide shaft is fixedly connected or integrally formed on the card loading seat, the integral shuffling barrel or the card feeding seat, the inner card loading guide shaft is sleeved with an inner card loading guide sleeve, and the inner card loading guide sleeve is fixedly connected to the card supporting plate. In this way, the inner card loading guide shaft will not occupy the shuffling space, the position of the card supporting plate and the size of the shuffling space will no longer affect and interfere with each other, the card supporting plate can be further pushed inward, so that the spacing between the card openings on the mahjong machine table can be further reduced.

[0015] Preferably, an extension arm is extended forward from the inner end of the card loading seat, and the inner card loading guide shaft of the card supporting plate is fixedly arranged on the extension arm. The card loading seat is provided with a card loading guide shaft seat on its outer section, and the outer card loading guide shaft of the card supporting plate is slidably installed in the card loading guide shaft seat.

[0016] Preferably, the inner card loading guide shaft of one card supporting plate is arranged between its inner end and the length edge of the other card supporting plate.

[0017] Preferably, the card-loading motor drives the card-pushing plate to move horizontally to push the cards through the card-pushing plate transmission mechanism; the card-pushing plate transmission mechanism includes a card-pushing frame, a horizontal-pushing slider, a horizontal-pushing cam and a horizontal-pushing rocker arm, the horizontal-pushing slider slides back and forth on the card-pushing frame, the card-pushing plate is fixed on the horizontal-pushing slider, the upper end of the horizontal-pushing rocker arm is movably connected to the horizontal-pushing slider, the lower end of the horizontal-pushing rocker arm is hinged to the card-loading seat through the horizontal-pushing rocker arm shaft, a horizontal-pushing rocker arm is fixed on the horizontal-pushing rocker arm shaft, the swinging end of the horizontal-pushing rocker arm movably cooperates with the horizontal-pushing cam, and the horizontal-pushing card-loading motor drives the horizontal-pushing slider to slide back and forth through the horizontal-pushing cam and the horizontal-pushing rocker arm to implement card pushing.

[0018] Preferably, the push card plate is fixed on the horizontal push slider in a manner that the front and rear positions can be adjusted. For example, the push card plate is fixed on the horizontal push slider through waist-shaped holes and fasteners. In this way, by adjusting the front and rear fixed positions of the push card plate on the horizontal push slider, mahjong tiles of different sizes can be used.

[0019] Preferably, the card loading motor drives the card loading plate to rise and fall through the card loading plate transmission mechanism; the card loading plate transmission mechanism includes two card loading curve cams, two card loading rocker arms, two card loading rocker arm shafts, a card loading rocker arm cam and two first gears, and the two card loading curve cams are respectively installed on the left and right sides of the bottom of the card loading plate; the two card loading rocker arms respectively cooperate with the two card loading curve cams for movement; the card loading rocker arm shaft is rotatably installed on the card loading seat, and the card loading rocker arm is fixedly arranged on the card loading rocker arm shaft; the card loading rocker arm cam is fixedly connected to the card loading rocker arm shaft, and a cam groove is provided on the card loading rocker arm cam; the first gear is rotatably installed on the card loading seat, and the first gear cooperates with the card loading rocker arm cam for transmission through a crank; the two first gears are driven by the push card loading motor to rotate synchronously.

[0020] A mahjong machine adopts the above-mentioned flat-push card loading device of the mahjong machine.

[0021] Since the present invention adopts the above technical scheme, the position of the card supporting plate can be further pushed inward without changing the overall layout of the mahjong machine, that is, without adjusting the placement position of the card feeding device, the position of the card receiving block in the card pushing device, and the position of the card receiving plate in the card pushing device, so that the distance between the card loading openings on the table of the mahjong machine (that is, the distance between the card supporting plates) is further reduced. In this way, the same mahjong machine only needs to replace or adjust individual parts to be suitable for a variety of mahjong tiles of different sizes, which greatly reduces the mold opening cost, manufacturing cost and warehousing cost of the mahjong machine manufacturer.

In other embodiments, the card bearing plate 72 can also be arranged on the card loading seat 70 in a manner that it can be lifted and lowered and driven to lift and lower by the horizontal push card loading motor 71. The specific structure of the horizontal push card loading device can refer to various embodiments disclosed in patent documents such as publication numbers CN109381855A, CN109794059A, CN112023390A, CN114247127A, CN114146397A, and CN117982871A.

[0071] In other embodiments of the present invention, two or three of the above-mentioned card feeding seat, card pushing seat and horizontal push card loading seat can also be integrally formed or fixedly connected as one, and two or three of the above-mentioned card feeding motor, card pushing motor and horizontal push card loading motor can also be the same motor, that is, two or three of the card feeding device, card pushing device and horizontal push card loading device share one motor.

[0072] The present invention is a windmill-shaped mahjong machine. Four card-loading openings are arranged on the table top of the mahjong machine. The four card-loading openings are inclined relative to the four side edges of the table top to form a windmill-shaped layout. Four card-supporting plates 74 in the four sets of card picking and transporting systems are respectively matched with the four card-loading openings. When the card-supporting plates 74 are raised, the card-supporting plates 74 are filled to the card-loading openings and are flush with the table top of the mahjong machine.

[0073] In this way, the horizontal push card loading device is tilted relative to the side edge of the table top board on the same side, and the card inlet end of the horizontal push card loading device is closer to the inside than the other end thereof, so that the four mahjong tiles are lifted onto the table top of the mahjong machine at once in the form of being tilted to the four edges of the table top board of the mahjong machine and close to the center of the table top board of the mahjong machine. By tilting the horizontal push card loading device, the corresponding card loading port and the side edge of the table top board on the same side of the supporting plate are also tilted, and when the mahjong tile wall rises to the table top board, it is already in a tilted state, which conforms to the player's playing habits, saves the player's manual card pushing process, and realizes the card-free pushing function. In addition, since the mahjong tile wall is pushed onto the supporting plate in a horizontal push manner, and then the supporting plate rises to the table top, there is no problem of falling cards.

[0074] like Figure 2 and Figure 8 As shown, in the present invention, the card holding block 62 of the card pushing device 6 is arranged outside the card outlet of the card feeding channel, one end of the card holding plate 72 extending along the length direction is the card inlet of the card storage channel, the card holding block 62 of the card pushing device 6 is arranged outside the card inlet, and the other end of the card holding plate 72 extending along the length direction is provided with a side baffle 721, the front and rear obstructions of the card storage channel are respectively a front baffle 742 and a card pushing plate 73, and the front baffle 742 is fixedly connected with the card supporting plate 74 or is integrally formed.

[0075] In the present invention, the height of the card outlet of the card delivery channel is lower than the height of the card support plate when it drops to the lowest position, which exceeds the thickness of a mahjong tile. In a preferred embodiment, the card receiving block 62 of the card pushing device has at least three height positions: the first card receiving position, the second card receiving position and the card pushing position. When stacking mahjong tiles: the card receiving block 62 first receives the first mahjong tile sent by the card delivery device at the first card receiving position; the card receiving block 62 then drops to the second card receiving position to receive the second mahjong tile sent by the card delivery device, and the second mahjong tile is stacked on the first mahjong tile; then, the card receiving block 62 rises to the card pushing position, and the card pushing head 63 pushes the two mahjong tiles stacked up and down out of the card receiving block 62 together; the card receiving block 62 drops and resets to the first card receiving position; the card pushing head 63 also resets, waiting for the next stacking. Among them, the card pushing position of the card receiving block 62 is higher than the second card receiving position by at least the thickness of two mahjong tiles.

[0076] In the present invention, the card receiving block 62 of the card pushing device 6 is arranged outside the shuffling frame, so the card outlet of the card feeding device 5 and the card inlet of the card pushing device 7 are also arranged outside the shuffling frame. This avoids the card receiving block from occupying the shuffling space when it descends, so that the shuffling frame and the shuffling plate can be maximized.

[0077] In one embodiment of the present invention, the setting of the card support plate can adopt the existing technology disclosed in patent documents such as publication number CN117982871A:

[0078] The card loading seat 70 of the push-on card loading device 7 will hollow out part or all of the inner wall near the shuffling plate, so that the edge of the shuffling plate 2 can expand to just below the card receiving plate 72, and the card feeding motor 51 of the card feeding device 5 can also extend to just below the card receiving plate 72. In this way, most of the card support plate 74 and a small part of the card receiving plate 72 are located above the shuffling frame, and the card delivery outlet of the card delivery device 5 and the card receiving block 62 of the card pushing device 6 are located directly below the card support plate 74, which can not only effectively increase the shuffling space while increasing the size of the shuffling plate, but also shorten the length of the card delivery channel of the card delivery device 5, thereby making the position settings of the card receiving block 62 of the card pushing device 6 and the card inlet of the horizontal push card loading device 7 more reasonable; reducing the interference restrictions of the horizontal push card loading device and the card delivery device on the shuffling plate and the shuffling space, so that the shuffling frame and the shuffling plate can be maximized. On the same size of the mahjong machine bottom plate, without increasing the thickness of the mahjong machine, the shuffling plate and the shuffling space are increased, for example, 108 pieces of 62 mahjong tiles can be shuffled on a 36-table mahjong machine. However, from Figure 1 It can be seen that the inner card-loading guide shaft 706 of the card-supporting plate 74 is still located on the outside of the shuffling plate 2. In the prior art, the inner and outer card-loading guide shafts of the card-supporting plate are fixed at the bottom of the card-supporting plate. When the card-supporting plate is lowered, the lower end of the inner card-loading guide shaft will be close to or even need to pass through the bottom plate, thus limiting the outward expansion of the shuffling plate and affecting the further increase of the shuffling space.

[0079] Therefore, in a preferred embodiment of the present invention, Figure 2 As shown, the inner card-loading guide shaft 706 of the card-supporting plate 74 is arranged above the inner side of the outer circumference of the shuffling plate 2, and the inner card-loading guide shaft 706 is fixedly connected or integrally formed on the card-loading seat 70, the integral shuffling barrel 4 or the card-delivering seat 53. The inner card-loading guide shaft 706 is sleeved with an inner card-loading guide sleeve 740, and the inner card-loading guide sleeve 740 is fixedly connected to the card-supporting plate 74. In this way, the length of the inner card-loading guide shaft 706 only needs to be slightly greater than the lifting height of the card-supporting plate 74, and it will not extend downward into the shuffling space to affect the shuffling. Therefore, the card-supporting plate can be further pushed inward and will not interfere with the shuffling space, so that the card-supporting plate is not limited by the shuffling frame (shuffling barrel), so that the same card-supporting plate can be shuffled with a larger shuffling plate, and a larger shuffling plate can shuffle larger cards with more piles, meeting the needs of more players. For example, on a 36-table mahjong machine, 120 pieces of 64-jong tiles can be shuffled and arranged, and the minimum edge distance of the card support plate can be 290 mm.

[0080] In this embodiment, an extension arm 705 is provided at the inner end of the card loading seat 70, and the inner card loading guide shaft 706 of the card holding plate 74 is fixedly provided on the extension arm 705. The card loading seat 70 is provided with a card loading guide shaft seat 704 on its outer section, and the outer card loading guide shaft 741 of the card holding plate 74 is slidably installed in the card loading guide shaft seat 704. In this way, the bearing structure of the card holding plate is more balanced, and the lifting guide positioning references on both sides of the card holding plate are on the card lifting seat, so the installation and debugging are more convenient, and the lifting action is more stable and reliable.

[0081] In this embodiment, the inner card loading guide shaft 706 of one card holding plate 74 is preferably arranged between its inner end and the length side of the other card holding plate 74. In this way, the gap between the two card holding plates can be fully utilized, which not only facilitates the arrangement of the extension arm and the card pushing and blocking structure, but also makes the structure reasonable, stable and reliable in movement, and also facilitates the formation of a good support for the narrow edge of the table top between the two card loading openings.

[0082] In other embodiments, the inner card loading guide shaft 706 of the card supporting plate 74 can also be arranged at the front side of its length side, that is, between the card supporting plate 74 and the central lifting device of the mahjong machine (between the card supporting plate and the card placing hole of the shuffling bucket). Such a structure is particularly suitable for the case where the inner card loading guide shaft of the card supporting plate is fixedly arranged on the shuffling bucket, and the overall structure is simpler and more reasonable.

[0083] In one embodiment of the present invention, the upper card holder can be provided by using the prior art disclosed in patent documents such as publication number CN117982871A:

[0084] The card loading seat no longer has a front side wall on the front side near the shuffling frame, so that the internal space of the card loading seat (the space below the card receiving plate) becomes an open space, allowing the shuffling plate / shuffling frame and the card feeding motor to extend into the open space, and the card loading seat becomes an open seat structure formed by the rear side wall, the top wall and the left and right side walls. Among them, the top wall of the card loading seat is used to form a fixed card receiving plate that does not rise or fall. Because the top wall is fixed, the thickness is relatively thin. The shuffling frame is arranged below it, and the height difference between the card outlet position of the card feeding device and the lowest position where the card supporting plate descends will not be further increased, nor will the thickness of the entire mahjong machine be increased. It is more reasonable than the bottom hollowing structure disclosed in the patent literature such as the publication number CN109794059A; the rear side wall of the card loading seat is used to install the flat push card loading motor 71 and the card loading transmission mechanism. In order to reduce the volume occupied by the card loading transmission mechanism in the open space (the lower space of the card receiving plate), it is preferred that the rear side wall is protruded backward so that it is recessed in front to form a number of grooves for accommodating some parts of the card loading transmission mechanism; the left and right side walls of the card loading seat are used to fix and connect the card loading guide shaft seat. In order to increase the overall strength of the card loading seat and facilitate injection molding, a bottom wall is also provided, but the bottom wall can be hollowed out at the interference with the shuffling plate and the card feeding motor to avoid affecting the two settings. However, the top wall of the card holder in this structure is thin-walled and long, resulting in poor structural strength and load-bearing capacity. In addition, the guide shaft seat inside the card holder and its connected side wall structure also limit the layout, maintenance and disassembly of the dish washing space and the card pushing device.

[0085] Therefore, in a preferred embodiment of the present invention, Figure 6 , Fig.16 and Fig.17As shown, the card loading seat 70 includes a card loading seat body 701 installed on the base plate 1, a card loading motor 71 and a card loading transmission mechanism for driving the card pushing plate 73 to translate and push cards and the card supporting plate 74 to lift and lower cards are all installed on the card loading seat body 701, the top wall of the card loading seat body 701 extending forward forms a part of the card bearing plate 72, and a cantilever portion 707 is extended forward from the inner side of the card loading seat body 701, the bottom of the cantilever portion 707 is hollow, and the top of the cantilever portion 707 forms a part of the card bearing plate 72, and the card pushing seat is arranged on the rear side of the cantilever portion 707 and is fixedly connected to the cantilever portion 707 and the card loading seat body 701 respectively. The inner end of the cantilever part 707 is connected to form a reinforced support, and an extension arm 705 is extended forward from the inner end of the cantilever part 707. The inner card loading guide shaft 706 of the card supporting plate 74 is fixedly set on the extension arm 705. The inner card loading guide shaft 706 is sleeved with an inner card loading guide sleeve 740. The inner card loading guide sleeve 740 is fixedly connected to the card supporting plate 74. The outer side of the card loading seat main body 701 is extended forward to be provided with a card loading guide shaft seat 704. The outer card loading guide shaft 741 of the card supporting plate 74 is installed in the card loading guide shaft seat 704. The outer card loading guide shaft 741 is fixed to the bottom of the card supporting plate 74 and rises and falls synchronously with the card supporting plate 74. In this way, the cantilever part and the extension arm are arranged in the hollow to avoid the card loading seat from occupying the shuffling space, the card loading seat body and the cantilever part are fixedly connected by the card pushing seat to enhance the structural strength and load-bearing capacity of the cantilever part, and the card loading motor and the card loading transmission mechanism are installed on the card loading seat body outside the shuffling barrel to avoid them from occupying the shuffling space. The structure is reasonable and does not affect each other, which is convenient for disassembly and maintenance.

[0086] In other embodiments, the outer card loading guide shaft 741 of the card supporting plate 74 can also be fixed on the card loading seat 70, and an outer card loading guide sleeve is sleeved on the outer card loading guide shaft 741, and the outer card loading guide sleeve is fixed to the bottom of the card supporting plate 74 and rises and falls synchronously with the card supporting plate 74.

[0087] In this embodiment, an extension part 703 is provided at the outer end of the card holder 70, and the extension part 703, the cantilever part 707 and the top wall extending forward from the main body 701 of the card holder together form a card bearing plate 72, and a side baffle 721 for blocking mahjong tiles is fixedly connected or integrally formed at the outer end of the extension part 703. This can prevent the top thin-walled structure of the card holder from being too long, which affects the structural strength and load-bearing capacity, and the provision of the extension part makes the flat-push card holder device have better versatility. According to the use requirements of mahjong machines of different specifications, it is sufficient to replace the appropriate extension part, without replacing the entire flat-push card holder device, thereby reducing the mold opening cost and stocking cost.

[0088] In this embodiment, the upper card holder body 701, the extension portion 703, the cantilever portion 707 and the extension arm 705 all adopt a grid-like reinforcement structure to increase their structural strength and load-bearing capacity.

[0089] In this embodiment, preferably, an opening extending from top to bottom is provided on the top wall of the card loading seat body 701 extending forward, and the card feeding motor 51 of the card feeding device 5 is located below the opening. A removable plate 702 is fixed in the opening, and the top of the removable plate 702 forms a part of the card bearing plate 72. In this way, when disassembling the card feeding device from the card shuffling barrel, the removable plate can be first removed to form an opening for the card feeding motor to pass from bottom to top, and then the card feeding device can be removed. The card feeding device can be taken out without disassembling the peripheral flat-push card loading device, and maintenance and disassembly are very convenient.

[0090] Further preferably, a card pushing rack 731 is installed on the card holder 70, and the opening position is located in front of the card pushing rack 731, so that the card feeding motor 51 can be installed close to the card suction wheel 52 or directly drive the card suction wheel 52, and the card feeding device is shorter and more convenient for maintenance and disassembly.

[0091] In this embodiment, the bottom of the card loading seat body 701 is preferably provided with a first card loading mounting foot 7011 for fixedly connecting to the integral card shuffling barrel and a second card loading mounting foot 7012 for fixedly connecting to the bottom plate 1. In this way, the card loading seat is positioned and fixed to the integral card shuffling barrel and the bottom plate, the overall positioning and installation of the movement of the mahjong machine is more convenient, and the overall connection structure is more reasonable and has higher strength.

[0092] In one embodiment of the present invention, the card support plate transmission mechanism can adopt the existing technology disclosed in patent documents such as publication numbers CN109381855A, CN112023390A, CN114247127A, CN114146397A, and CN117982871A. For example, the card support plate transmission mechanism includes: a card loading curve cam, two card loading curve cams are respectively installed on the left and right sides of the bottom of the card support plate, and the left and right ends of the bottom of the card support plate are connected to the upper and lower card loading seats through two guide shafts or sliding sleeves. Sliding connection; card-loading rocker arm, the two card-loading rocker arms respectively cooperate with the two card-loading curved cams for movement; the card-loading rocker arm shaft, the card-loading rocker arm shaft is rotatably mounted on the card-loading seat, and the two card-loading rocker arms are respectively fixed on the two card-loading rocker arm shafts; the card-loading driving cam, the card-loading driving cam is mounted on the card-loading seat and driven to rotate by the flat-push card-loading motor; the card-loading connecting rod, the card-loading connecting rod is driven to move by the card-loading driving cam; the card-loading connecting rod drives the two card-loading rocker arm shafts to rotate synchronously, thereby driving the card supporting plate to move up and down by driving the two card-loading rocker arms to rotate. In this way, the volume of the card loading curve cam is small, the installation position of the card loading rocker arm is high and intermittent swing is adopted, and then the card loading rocker arm is suspended by extending the card loading rocker arm shaft forward, so that the card loading connecting rod and the card loading driving cam can be set further back, so that the card supporting plate transmission mechanism occupies less shuffling space, and the diameter of the shuffling plate can be increased, and the shuffling space can be increased, which can not only improve the shuffling efficiency, but also reduce the probability of mahjong cards colliding with each other on the shuffling plate, so as to achieve the effect of reducing shuffling noise. However, the card loading rocker arm shaft and cam connecting rod driving mechanism set in the air lead to insufficient support strength and weak load-bearing capacity of the card supporting plate, and the movement of the connecting rod is easily blocked, the two card loading rocker arms are unevenly stressed, and the synchronization is poor, which makes installation, maintenance and debugging difficult.

[0093] Therefore, in a preferred embodiment of the present invention, Figures 9 to 15 As shown, the card support plate transmission mechanism includes:

[0094] Two card loading curve cams 744, which are respectively installed on the left and right sides of the bottom of the card supporting plate 71;

[0095] Two card loading rocker arms 743, the two card loading rocker arms 743 respectively cooperate with two card loading curve cams 744 for movement;

[0096] Two card loading rocker arm shafts 745, the card loading rocker arm shafts 745 are rotatably mounted on the card loading seat 70, and the card loading rocker arm 743 is fixedly arranged on the card loading rocker arm shafts 745;

[0097] Two card loading rocker arm cams 746, the card loading rocker arm cams 746 are fixedly connected to the card loading rocker arm shaft 745, and the card loading rocker arm cams 746 are provided with cam grooves 7461;

[0098] Two first gears 748 are rotatably mounted on the card loading seat 70 , and the first gears 748 cooperate with the card loading rocker arm cam 746 through the crank 747 for transmission; the two first gears 748 are driven by the push card loading motor 71 to rotate synchronously.

[0099] In this way, a gear transmission mechanism is adopted, the cam is installed on the upper rocker arm shaft and transmitted with the crank gear, which has a large torque transmission, better stability and synchronization, more convenient installation and debugging, and more convenient maintenance and disassembly.

[0100] This embodiment is preferred, and further includes two second gears 749, which mesh with each other and rotate synchronously, and the two second gears 749 are respectively meshed with the two first gears 748 for transmission, and one of the second gears 749 is driven to rotate by the horizontal push card motor 71. Such a gear transmission mechanism has a reasonable structure, smooth movement, large transmission torque, and is more convenient to install and maintain.

[0101] In this embodiment, the two card loading rocker arms 743 rotate synchronously in opposite directions during the lifting process of the card supporting plate 74, and the two first gears 748 rotate synchronously in opposite directions. In this way, the lifting structure of the card supporting plate 74 is reasonable and the movement is smooth.

[0102] In this embodiment, the crank 747 is preferably driven by the cam groove 7461 on the upper rocker cam 746 through a roller, and the crank 747 is fixedly connected or integrally formed with the first gear 748. In other embodiments, the crank gear may not highlight the shape of the crank, but a roller or column for cooperating with the cam groove is installed at the eccentric position of the first gear to form a de facto crank gear transmission structure.

[0103] In the preferred embodiment, the rocker arm 743, the rocker arm shaft seat 7451 and the rocker arm cam 746 are sequentially sleeved on the rocker arm shaft 745 from front to back. In this way, not only can the occupation and influence of the rocker arm cam and the gear transmission mechanism on the shuffling space be reduced, but also the transmission structure is more stable and reliable.

[0104] In this preferred embodiment, the front end of the card loading rocker arm shaft 745 is fixedly connected or integrally formed with the card loading rocker arm 743, the rear end of the card loading rocker arm shaft 745 is installed on the card loading seat body 701 through a bearing, and the card loading rocker arm cam 746 is fixedly connected or integrally formed with the card loading rocker arm shaft 745.

[0105] In this embodiment, the bottom of one card loading rocker shaft seat 7451 near the card storage channel entrance on the card loading seat 70 is supported by the shuffling barrel, and the bottom of the other card loading rocker shaft seat 7451 is supported by the support column 75, and the support column 75 is fixedly connected or integrally formed with the card loading seat 70. In this way, the supporting strength and load-bearing capacity of the card supporting plate can be improved to the greatest extent.

[0106] In this preferred embodiment, the licensing rocker arm shaft seat 7451 consists of two parts, the upper part of the licensing rocker arm shaft seat 7451 is fixed to the front side of the licensing seat 70 by a horizontally arranged fastener, and the upper and lower parts of the licensing rocker arm shaft seat 7451 are fixedly connected together by vertically arranged fasteners.

[0107] The preferred embodiment of the present invention is that the card pushing plate transmission mechanism includes a card pushing frame 731, a horizontal pushing slider 7311, a horizontal pushing cam 732 and a horizontal pushing swing rod 734. The horizontal pushing slider 7311 slides back and forth on the card pushing frame 731 along the guide rod. The card pushing plate 73 is fixed on the horizontal pushing slider 7311. The upper end of the horizontal pushing swing rod 734 is movably connected with the horizontal pushing slider 7311. The lower end of the horizontal pushing swing rod 734 is hinged to the card loading seat 70 through a horizontal pushing swing rod shaft 735. A horizontal pushing rocker arm 733 is fixed on the horizontal pushing swing rod shaft 735. The swinging end of the horizontal pushing rocker arm 733 is movably matched with the horizontal pushing cam 732 through a roller. A second gear 749 is driven to rotate by the horizontal pushing card loading motor 71, and another second gear 749 is coaxially fixed and synchronously rotated with the horizontal pushing cam 732, so that the horizontal pushing card loading motor 71 drives the horizontal pushing slider 7311 to slide back and forth through the horizontal pushing cam 732 and the horizontal pushing swing rod 734 to implement card pushing. More preferably, the horizontal push rocker arm 733 is arranged between the horizontal push card loading motor 71 and the horizontal push cam 732. More preferably, a card pushing cover plate 736 is fixedly arranged above the card pushing plate 73. In other embodiments, the card supporting plate transmission mechanism and the card pushing plate transmission mechanism can also refer to various implementation methods disclosed in patent documents such as publication numbers CN109381855A, CN109794059A, CN112023390A, CN114247127A, CN114146397A, and CN117982871A.

[0108] This embodiment is preferred, as Fig.21 As shown, there is a gap C between the card bearing plate 72 and the card supporting plate 74, and the width of the gap C is less than one-third of the length of the mahjong tiles. When the card supporting plate 74 is lowered to the bottom, the height of the top supporting plane of the card supporting plate 74 is not higher than the height of the card storage plane of the card supporting plate 72. In this way, the position of the card supporting plate can be further pushed inward without changing the overall layout of the mahjong machine (the placement position of the card feeding device, the position of the card bearing block in the card pushing device, and the position of the card bearing plate in the card pushing device are not adjusted), so that the distance between the card supporting plates can be further reduced. More preferably, the width of the gap C is 3 to 15 mm, and the height difference between the top supporting plane of the card supporting plate 74 and the card storage plane of the card supporting plate 72 is 0.5 to 1.5 mm.

[0109] In other embodiments, a transition plate may be provided between the card receiving plate and the card supporting plate, and when the card pushing plate pushes the cards, the multiple mahjong tiles on the card receiving plate are pushed to the card supporting plate via the transition plate. In this way, the position of the card supporting plate can be pushed further inward, thereby pushing the mahjong wall on all sides inward, and the distance between the card supporting plates is minimized. The specific arrangement of the transition plate can refer to various embodiments disclosed in patent documents such as publication numbers CN114146396A and CN114146398A.

[0110] In this embodiment, the action process of the push card loading device is as follows:

[0111] like Figures 9 to 12 As shown, the card support plate 74 is in a raised state, and the card loading motor 71 drives the crank gear 748 to rotate 75 degrees to 110 degrees, and the card support plate 74 moves from a high point to a low point to receive the cards. Fig.13 and Fig.14 As shown; the crank gear 748 continues to rotate 80 degrees to 125 degrees, the card pushing plate 73 pushes the mahjong tiles on the card receiving plate 72 onto the card supporting plate 74, the crank gear 748 continues to rotate 105 degrees to 160 degrees, the card supporting plate 74 rises to the tabletop for playing cards, and the whole process repeats itself.

[0112] When the pushing board pushes the mahjong tile wall on the card supporting board to the card supporting board, in order to prevent the mahjong tiles from being pushed out of the card pushing board and falling onto the shuffling plate or getting stuck on the card supporting board, a card blocking frame is preferably provided on the inner side of the square card supporting board to prevent the mahjong tile wall on the card supporting board from continuing to move inward.

[0113] The horizontal push card blocking structure can adopt the prior art disclosed in patent documents such as publication number CN112023390A, CN117982870A, CN114247127A, CN114146397A, CN117982871A, CN219149199U, etc.: the card blocking frame extends outward with an outer card blocking portion so as to match the length of each card supporting plate, and blocks the mahjong cards on the card supporting plate from moving inward from the inner side of the card supporting plate, thereby ensuring that the mahjong card wall horizontally pushed onto the card supporting plate is uniform. Because in the windmill-shaped mahjong machine structure with a fixed card supporting plate, the card pushing head of the card pushing device moves at a relatively high position, which is higher than the height of the card supporting plate of the horizontal push card loading device, which causes the card pushing head in the card pushing device to interfere with the outer card blocking portion of the adjacent card blocking frame. Therefore, in a preferred embodiment, the outer card-blocking part of the adjacent card-blocking frame will be provided with an opening above the card-bearing block of the own card-pushing device to avoid affecting the card-pushing head of the own card-pushing device, and when pushing the cards horizontally, the card-pushing head will stay in a suitable position so that it can realize the horizontal pushing and blocking function together with the card-blocking frame and its outer card-blocking part. However, because the card-pushing head is a movable part after all, its staying position is in a position where it is not close to the front and back, and it cannot be extremely accurate (otherwise the cost will be very high), it is difficult to ensure that the back side of the card-pushing head is flush with the card-blocking frame and its outer card-blocking part, and the card-pushing head also has inevitable looseness caused by the transmission gap. Therefore, in actual use, there is often a problem that the mahjong tile wall of the horizontal push card is not neat.

[0114] In order to solve the above problem, one implementation method is: a baffle is installed on the back side of the card pushing head, the baffle can move relative to the card pushing head (relatively small range of movement), the baffle moves horizontally with the card pushing head when the card pushing device pushes cards, and the baffle can be positioned and fixed with the card supporting plate when the card pushing device pushes cards horizontally, so that it is flush with the card blocking frame and its outer card blocking part, and blocks the mahjong cards on the card supporting plate from moving inward from the inner side of the card supporting plate, thereby ensuring that the mahjong wall of the horizontally pushed cards is uniform. In this way, by setting a baffle that is movable relative to the card pushing head, it is positioned and fixed by the card supporting plate when the cards are pushed horizontally, so as to ensure that it is flush with the card blocking frame and its outer card blocking part, thereby overcoming the defect that the card pushing head cannot be relatively positioned and is easy to loosen when the card blocking device is used. Another embodiment is: the horizontal push card blocking mechanism includes a card blocking frame for blocking the mahjong cards on the card supporting plate of the horizontal push card loading device from moving inward, the card blocking frame is located on the inner side of the card supporting plate, and the card blocking frame extends outward with an outer card blocking portion; the outer card blocking portion is provided with an opening above the card supporting block of the card pushing device for a card pushing head of the card pushing device to move horizontally through; and also includes a movable baffle, the movable baffle is installed on the outer card blocking portion in a manner that it can be flipped up and down and swung, the movable baffle is driven by the card pushing head or the card supporting plate to flip and swing up and down, and is reset by an elastic member.

[0115] The above-mentioned card retaining frame and the outer card retaining part can be two relatively independent parts or multiple parts, which are directly fixedly connected or indirectly fixedly connected through other intermediate parts. In other preferred embodiments, the card retaining frame and the outer card retaining part can be integrally formed.

[0116] This embodiment is preferably provided with a flat push plate blocking structure, such as Fig. 20 As shown, the four card baffle frames are connected as a whole to form a square card baffle cover 8, and the outer card baffle parts of the four sides include two inner and outer parts, namely the inner card baffle plate 54 and the outer card baffle plate 9, between which is an opening for the card pusher 63 to pass through, and a movable baffle plate 92 is provided in the opening, and the movable baffle plate 92 is installed on the table top of the mahjong machine in a way that it can be flipped up and down and is reset by an elastic member; wherein, the outer card baffle plate 9 is an independent component directly fixed on the bottom plate of the mahjong machine, and the inner card baffle plate 54 can be an independent component fixed on the card baffle cover 8, the integral shuffling barrel 4 or the card feeding seat 53, and can also be integrally formed with the card baffle cover 8, the integral shuffling barrel 4 or the card feeding seat 53.

[0117] In this embodiment, the inner card baffle plate 54 is fixedly connected or integrally formed with the card feeding seat 53. This facilitates the maintenance and disassembly of the card feeding device. Fig. 22 and Fig.23 As shown, the inner card baffle plate 54 is integrally formed with the inner shell 532 of the card feeding seat 53.

[0118] This embodiment is preferred, as Figure 5 and Fig. 20 As shown, a card block 64 is arranged outside the card outlet of the card delivery device 5, and a card delivery side block 5311 is arranged on the card delivery seat 53. When the card receiving block 62 receives the mahjong tiles delivered by the card delivery device 5, the card block 64 and the card outlet of the card delivery device are respectively located on two opposite sides of the card receiving block 62, and the card delivery side block 5311 and the card pusher seat 65 / card upper seat 70 (cantilever portion 707) are respectively located on the other two opposite sides of the card receiving block 62. In this way, not only can the mahjong tiles be prevented from falling into the space outside the card receiving block to cause malfunctions, but also the structure is more reasonable and reliable.

[0119] This embodiment is preferred, as Figure 2 and Figure 5As shown, in the same group of card picking and transporting system, the angle A between the length side of the card supporting plate 74 and the card discharging direction of the card feeding device 5 is 75°~85°, and the angle B between the card pushing direction of the card pushing device 6 and the card discharging direction of the card feeding device 5 is 75°~85°; the inner card blocking plate 54 is pressed above the card discharging port of the card feeding channel, and the maximum distance between the outer end of the inner card blocking plate 54 and the inner end of the card pushing head 63 is less than the width of a mahjong tile. In this way, not only the angle setting of the card suction wheel of the conveying device and the shuffling plate is more reasonable, the shuffling space is larger, and the shuffling and picking efficiency is higher, but also the mahjong tiles can be prevented from being strung to the top of the card feeding seat when the card receiving block receives the cards and the card pushing head pushes the cards, causing a malfunction.

[0120] In this embodiment, the blocking surface of the blocking block 64 facing the card outlet of the card delivery device 5 forms an angle of 85° to 89° with the card delivery direction of the card delivery device 5, and the blocking surface of the blocking block 64 forms an angle of 5° to 10° with the card feeding direction of the card storage channel. In this way, the angle position of the mahjong tiles on the card receiving block is closer to the card feeding direction of the card storage channel, avoiding the mahjong tiles from being pushed too far when the pusher pushes the tiles, causing a push block or a mahjong tile skipping.

[0121] This embodiment is preferably provided with a card pushing and guiding structure, such as Figure 5 and Fig. 20 As shown, the outer baffle plate 9 is provided with a card guide 91 on one side close to the opening, the card guide 91 is embedded in the outer baffle plate 91 and fixed by fasteners, the inner end of the card guide 91 extends into the opening and is provided with an outer card guide surface 911 for contacting mahjong tiles, the outer end of the inner baffle plate 54 is provided with an inner card guide surface 541 for contacting mahjong tiles, the card pushing path of the card pushing head 63 is located between the outer card guide surface 911 and the inner card guide surface 541, the outer card guide surface 911 and the inner card guide surface 541 are arranged relative to each other and the two form a trumpet shape from large to small along the card pushing direction of the card pushing head, so that the mahjong tiles are guided to the card entry port of the card storage channel when the card pushing head pushes the tiles. In this way, the angle direction of the mahjong tiles can be adjusted through the trumpet during the card pushing process of the card pushing head, so that the angle direction of the mahjong tiles entering the card storage channel of the flat push card loading device is consistent with the length side direction of the card supporting plate and is neatly arranged.

[0122] Preferably, in this embodiment, an angle of 5° to 10° is formed between the outer card guiding surface 911 of the card guiding member 91 and the card feeding direction of the card storage channel, and an angle of 5° to 10° is formed between the inner card guiding surface 541 of the inner card baffle plate 54 and the card feeding direction of the card storage channel.

[0123] In this embodiment, the top of the card block 64 extends into the opening and forms a card-pushing card-pushing surface that is flush with the outer card-pushing plate 9 and is used for pushing and guiding cards, and a card-pushing and card-guiding surface that cooperates with the card-guiding member 91 and is used for pushing and guiding cards; the gap between the card block 64 and the card-guiding member 91 above it and the gap between the card block 64 and the outer card-pushing plate 9 outside it can be used for the connecting arm 631 connecting the card-pushing head 63 to the card-pushing seat to pass through. In this way, the action structure is simple and reasonable.

[0124] In this embodiment, the card block 64 is preferably fixedly mounted on the card pusher seat in an adjustable manner, and the card guide 91 is fixedly mounted on the outer card block plate 9 in an adjustable manner. In this way, mahjong tiles of different sizes can be adapted by adjusting the mounting positions of the card block and the card guide. In other embodiments, the card block 64 can also be fixedly connected or integrally formed with the card pusher seat or the outer card block plate, and the card guide 91 can also be fixedly connected or integrally formed with the outer card block plate 9.

[0125] In one embodiment of the present invention, the shuffling barrel can adopt the prior art disclosed in patent documents such as publication number CN117982871A: two adjacent card feeding devices 5 are connected by a connecting wall, and the four card feeding devices 5 in the four groups of card picking and transporting systems are connected end to end by four connecting walls to form a shuffling frame (with a shuffling space inside), the shuffling frame is arranged around the shuffling plate 2, the card inlet of the card feeding device 5 is located on the inner wall of the shuffling frame, the card outlet of the card feeding device 5 is located on the outer side of the shuffling frame, and four card feeding motors 51 are installed on the outer side wall of the shuffling frame. However, the shuffling frame with such a spliced ​​structure has too many parts and components, which are complicated to install, the overall strength of the shuffling frame is poor, the installation positioning accuracy is low, and it takes up a lot of space, and it is also very inconvenient to disassemble and repair the card feeding device.

[0126] Therefore, in a preferred embodiment of the present invention, an integral shuffling barrel formed by one-piece injection molding is used, such as Figure 3 , Figure 6 , Fig.18 and Fig.19As shown, the card feeding devices 5 of the four sets of card picking and transporting systems are all installed on an integral shuffling barrel 4, and the integral shuffling barrel 4 covers the shuffling plate 2 and is fixed on the bottom plate 1. The top of the integral shuffling barrel is a square mounting platform 42, and the center of the square mounting platform 42 is a card placement hole 41. The bottom of the integral shuffling barrel is an annular mounting ring 46. The outer diameter of the mounting ring 46 is larger than the square mounting platform 42. The square mounting platform 42 is connected to the mounting ring 46 through four barrel walls. A card feeding mounting port 47 for installing a card feeding device is provided between two adjacent barrel walls. A card supporting plate step 43 and a card receiving plate step 44 are formed on each barrel wall. The card supporting plate step 43 is located above the inner side of the card receiving plate step 44, and the height difference between the two is greater than the thickness of a mahjong tile (that is, close to the height of the front baffle 742, generally 25 to 55 mm). The card supporting plate step 43 is located below the card supporting plate 74 in the horizontal push card loading device, and the card receiving plate step 44 is located below the card receiving plate 72 in the horizontal push card loading device.

[0127] In this way, the use of an integral shuffling barrel has fewer parts and fewer screws than a shuffling frame made of four-sided card feeding devices, which is more convenient to install. The card feeding device can be made shorter, and maintenance and disassembly are more convenient. The barrel wall is a thin-walled structure, which is easy to form hollowing and avoidance structures, occupies less space, and has a large internal shuffling space. The overall shuffling barrel has better force strength and is not easy to deform. It is easy to install, position and debug, and is convenient for positioning, installing and supporting the card loading seat, card pushing seat and card feeding seat.

[0128] This embodiment is preferred, as Fig.18 and Fig.19 As shown, each barrel wall is provided with a card guide step 45 on one side near the card feeding installation port 47, and the card guide step 45 is located between the card receiving plate step 44 and the installation ring 46 and on the card inlet side of each barrel wall near the card receiving channel. In this way, a card guide space can be formed between the shuffling plate and the card guide step in the shuffling barrel to prevent mahjong cards from piling up, thereby limiting the height of mahjong cards entering under the card suction wheel, preventing cards from getting stuck at the card suction wheel, and improving the shuffling efficiency.

[0129] In this embodiment, the square mounting platform 42 is provided with a vent 421, and a fan 422 is installed on the vent 421. This facilitates ventilation, dehumidification and deodorization of the shuffling space.
