Description

TECHNICAL FIELD

[0001] The utility model belongs to mahjong machine manufacturing field, especially relate to a mahjong machine and flat push up card device. BACKGROUND

[0002] Mahjong is a kind of leisure and entertainment tool and is loved by the masses, and is listed as a sports competition. The traditional mahjong machine four mahjong tiles are parallel to the four edges of the tabletop after being lifted to the tabletop, and the mahjong tiles are very close to the table edge, which is unreasonable, and the player needs to manually move the mahjong tiles to the appropriate position before picking up the tiles. In the process of moving the mahjong tiles, the mahjong tiles are easy to fall, which brings inconvenience to the player.

[0003] Patent documents with publication numbers CN109381855A, CN109794059A and CN112023390A disclose a large windmill-shaped mahjong machine. The flat push up card device is inclinedly arranged relative to the side edge of the tabletop panel on the same side. The card inlet end of the flat push up card device is closer to the other end. The four mahjong tiles of the mahjong machine are lifted to the tabletop of the mahjong machine in a form of being inclined to the four edges of the tabletop panel of the mahjong machine and being close to the center of the tabletop panel of the mahjong machine. By incliningly arranging the flat push up card device, the card inlet and the card supporting plate corresponding to the flat push up card device are also in an inclined state relative to the side edge of the tabletop panel on the same side. When the mahjong tile wall is lifted to the tabletop panel, it is already in an inclined state, which saves the process of manually pushing the tiles by the player, conforms to the playing habit of the player, and there is no problem of turning over the tiles because the mahjong tile wall is pushed to the card supporting plate in a flat push manner and is lifted to the tabletop panel from the card supporting plate. However, compared with the common four-port mahjong machine (the flat push up card device is parallelly arranged relative to the side edge of the tabletop panel on the same side), the inclined arrangement of the flat push up card device makes the card inlet end closer to the center of the tabletop panel of the mahjong machine, which affects the arrangement of the shuffling large disc and occupies the shuffling space. In order to increase the size of the shuffling large disc to play larger mahjong tiles, generally, a part of the card supporting plate of the flat push up card device is arranged above the tile feeding device. This results in a large height difference between the tile outlet of the tile feeding device and the lowest position of the card supporting plate, which causes the lifting span of the tile supporting block in the tile pushing device to be too large, the tile pushing efficiency is low, the operation is unstable, and the mahjong tiles are easy to be mixed and jammed.

[0004] Patent literature with publication number CN109381855A and the like disclose a mahjong machine. In order to avoid the guiding sliding shaft at the inner side end of the card lifting plate (card supporting plate) from occupying the shuffling space, the sliding shaft at the inner side end of the card lifting plate is cancelled, and the inner side end of the card lifting plate is fixedly connected with the adjacent another card lifting plate through a fixing sheet, so that the four card lifting plates are connected as a whole and synchronously lifted. However, because the four card lifting plates are connected as a whole and have a large volume, it is difficult to synchronously lift the card lifting plates driven by the four card feeding motors, and the action stability of the card feeding mechanism is poor and the card feeding mechanism is prone to be stuck and damaged. In addition, the size of the shuffling disc is also limited by the blocking of the card supporting device (card supporting plate and the flower grid plate below the card supporting plate) and cannot be increased.

[0005] Patent literature with publication number CN109794059A and the like disclose an automatic mahjong machine. A gap for letting the shuffling disc is arranged between the bottom of the flat pushing and lifting card device and the bottom plate, so that the shuffling disc can extend into the gap, and the diameter size of the shuffling disc is no longer limited by the interference of the flat pushing and lifting card device. The end of the flat pushing and lifting card device away from the center of the shuffling disc is fixed on the bottom plate, and the rest of the flat pushing and lifting card device is suspended relative to the shuffling disc. 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 flat pushing and lifting card device and increase the shuffling gap. However, the bottom is partially hollowed out, and the connecting rod mechanism and the hinge point are all arranged directly below the card lifting plate. Therefore, the hollow height of the bottom of the flat pushing and lifting card device is limited, the shuffling space is not actually increased much, and the flat pushing and lifting card device arranged above the card feeding device not only increases the thickness of the mahjong machine, but also causes a large height difference between the card outlet height of the card feeding device and the lowest position of the card lifting plate, resulting in a large lifting span (at least the thickness of three mahjong tiles) of the card supporting block in the pushing card device, low tile pushing efficiency, unstable operation, and easy tile disorder and jamming. In addition, arranging the tile pushing device in the shuffling disc or above the edge of the shuffling disc also increases the thickness of the mahjong machine and occupies the shuffling space, and the different transmission stages and lengths of the two card lifting rocker arms also easily cause asynchronization or unstable operation.

[0006] Patent literature with publication numbers CN112023387A and CN112023390A and the like disclose a mahjong machine and a flat pushing and lifting card device thereof. The card supporting plate is also lifted and lowered by the flat pushing and lifting motor. Therefore, the size of the shuffling disc is also limited by the blocking of the card supporting plate, the flower grid plate below the card supporting plate and the lifting mechanism.

[0007] Therefore, the flat push-up tile type windmill-shaped mahjong machine disclosed in the above patent document has the four-wall mahjong tiles placed in a windmill shape and inclined, which is more outward relative to the four-wall mahjong tiles of the slope-up tile type windmill-shaped mahjong machine. Generally, the player still needs to manually push the mahjong tile wall a little bit to make it suitable for the player to play mahjong, which still causes inconvenience to the player. The main reason is that the flat push-up tile device interferes with the shuffling large disc and the tile feeding device at the edge of the shuffling large disc, which causes the flat push-up tile device and the tile supporting plate for lifting tiles to be unable to be pushed further inward, otherwise, it will excessively occupy the shuffling space, and the maximum size of the mahjong tiles used by the mahjong machine will be greatly reduced.

[0008] Therefore, the patent documents with publication numbers CN117982870A, CN117982871A, CN117982868A, etc. disclose a mahjong machine and a flat push-up tile device thereof, as shown in the drawings. Figure 1 As shown, the dashed line schematically shows the flat push-up tile device. The mahjong machine includes a shuffling large disc 2 located at the center of the machine frame bottom plate. Four groups of tile picking and carrying systems are arranged around the shuffling large disc 2. The tile picking and carrying system includes a tile feeding device 5, a flat push-up tile device, and a tile pushing device. The flat push-up tile device includes a tile supporting plate 72, a tile supporting plate 74, and a tile pushing plate 73. The tile supporting plate 74 is located at the inner side of the tile supporting plate 72. The tile pushing plate 73 is located at the outer side of the tile supporting plate 72 and pushes the tiles from the outside to the inside. One end of the tile supporting plate 72 extending along the length direction is an tile inlet. The tile inlet is provided with a tile supporting block 62 of the tile pushing device. A tile pushing motor 71 drives the tile pushing plate 73 to translate to push the tiles and drives the tile supporting plate 74 to lift to push up the tiles. The tile supporting plate 74 is respectively arranged to be inclined relative to the side edges of the table plate. Four walls are independently flat pushed up. By partially or completely hollowing the tile pushing-up seat of the flat push-up tile device close to the inner side wall of the shuffling large disc, the edge of the shuffling large disc can be expanded to the directly below the tile supporting plate, and the tile feeding motor of the tile feeding device can also be extended to the directly below the tile supporting plate. In this way, most of the tile supporting plate and part of the tile supporting plate are located above the shuffling frame. Not only can the size of the shuffling large disc be increased while effectively increasing the shuffling space, but also the length of the tile feeding channel of the tile feeding device can be shortened, so that the positions of the tile supporting block of the tile pushing device and the tile inlet of the flat push-up tile device are more reasonable. The interference and limitation of the flat push-up tile device and the tile feeding device on the shuffling large disc and the shuffling space are reduced, so that the shuffling frame and the shuffling large disc can be maximized. On the same size of the mahjong machine bottom plate, without increasing the thickness of the mahjong machine, the size of the shuffling large disc and the shuffling space are increased, for example, 108 pieces of 62 mahjong tiles are arranged and shuffled on a 36 table mahjong machine. However, from the perspective of the player, the mahjong tiles are still not pushed far enough, and the player still needs to manually push the mahjong tiles a little bit to make it suitable for the player to play mahjong, which still causes inconvenience to the player. Figure 1 It can be seen that the inner side tile feeding guide shaft 706 of the tile supporting plate 74 is still located on the outer side of the shuffling large disc 2. In the prior art, the inner and outer tile feeding guide shafts of the tile supporting plate are fixed at the bottom of the tile supporting plate. When the tile supporting plate is lowered, the lower end of the inner side tile feeding guide shaft will approach or even need to pass through the bottom plate, thereby limiting the expansion of the shuffling large disc and affecting the further increase of the shuffling space.

[0064] The flat pushing-up tile device 7 comprises a tile receiving plate 72 for receiving and arranging multiple piles of mahjong tiles, a tile supporting plate 74 for one-time feeding of the multiple piles of mahjong tiles onto the table top, and a tile pushing plate 73 for pushing the multiple piles of mahjong tiles on the tile receiving plate 72 onto the tile supporting plate 74. The tile receiving plate 72 is provided with a tile storage channel for storing the arranged multiple piles of mahjong tiles. The tile supporting plate 74 is located on the inner side of the tile receiving plate 72 and can be lifted up and down. The tile pushing plate 73 is located on the outer side of the tile receiving plate 72 and pushes the tiles from outside to inside. In a preferred embodiment, the flat pushing-up tile device further comprises a tile feeding seat 70 and a flat pushing-up tile motor 71. The tile receiving plate 72 is fixedly arranged on the tile feeding seat 70. The tile feeding seat 70 is provided with a tile feeding transmission mechanism. The flat pushing-up tile motor 71 drives the tile pushing plate 73 to horizontally push the tiles and drives the tile supporting plate 74 to lift up and down to feed the tiles. The tile feeding transmission mechanism comprises a tile supporting plate transmission mechanism for driving the tile supporting plate 74 to lift up and down, and a tile pushing plate transmission mechanism for driving the tile pushing plate 73 to horizontally push the tiles. In other embodiments, the tile receiving plate 72 can also be arranged on the tile feeding seat 70 in a manner capable of being lifted up and down and driven to lift up and down by the flat pushing-up tile motor 71. The specific structure of the flat pushing-up tile device can refer to various embodiments disclosed in patent documents with publication numbers CN109381855A, CN109794059A, CN112023390A, CN114247127A, CN114146397A, CN117982871A, etc.

[0065] In other embodiments of the present application, two or three of the tile feeding seat, the tile pushing seat and the flat pushing-up tile seat can be integrally formed or fixedly connected as a whole. Two or three of the tile feeding motor, the tile pushing motor and the flat pushing-up tile motor can be the same motor, i.e., two or three of the tile feeding device, the tile pushing device and the flat pushing-up tile device share one motor.

[0066] The present application is a windmill-shaped mahjong machine. Four tile feeding ports are arranged on the mahjong machine table top plate. The four tile feeding ports are arranged along the four side edges of the table top plate in a tilted manner to form a windmill-shaped layout. Four tile supporting plates 74 in four tile picking and carrying systems are matched with the four tile feeding ports respectively. When the tile supporting plates 74 are lifted up, the tile supporting plates 74 are filled into the tile feeding ports and are flush with the mahjong machine table top plate.

[0067] In this way, the flat pushing and feeding device is arranged obliquely relative to the side edge of the same side of the table panel, the feeding opening end of the flat pushing and feeding device is closer to the other end, and the quadrilateral mahjong tiles are lifted onto the mahjong machine table panel in a one-time manner and obliquely relative to the four edges of the mahjong machine table panel and close to the center of the mahjong machine table panel. By arranging the flat pushing and feeding device obliquely, the feeding opening and the tile supporting plate corresponding to the flat pushing and feeding device are also arranged obliquely relative to the side edge of the same side of the table panel. When the mahjong tile wall is lifted to the table panel, the mahjong tile wall is already in an oblique state, which conforms to the playing habit of the player, saves the process of manually pushing the mahjong tiles by the player, realizes the function of free pushing, and since the mahjong tile wall is pushed to the tile supporting plate in a flat pushing manner and then lifted to the table panel from the tile supporting plate, the problem of reversed tiles does not exist.

[0068] As shown in Figure 2 and Figure 8 In the utility model, the tile supporting block 62 of the pushing device 6 is arranged outside the feeding opening of the feeding channel, one end of the tile supporting plate 72 extending along the length direction is the feeding opening of the tile storage channel, the tile supporting block 62 of the pushing device 6 is arranged outside the feeding opening, the other end of the tile supporting plate 72 extending along the length direction is provided with a side baffle 721, the front and back blocks of the tile storage channel are respectively a front baffle 742 and a pushing plate 73, and the front baffle 742 is fixedly connected or integrally formed with the tile supporting plate 74.

[0069] In the utility model, the height of the feeding opening of the feeding channel is lower than the height of the tile supporting plate descending to the lowest position and exceeds the thickness of one mahjong tile. In the preferred embodiment, the tile supporting block 62 of the pushing device has at least three height positions: a first tile supporting position, a second tile supporting position and a pushing position. When the mahjong tiles are pushed in stacks: the tile supporting block 62 first supports the first mahjong tile sent out by the feeding device at the first tile supporting position; the tile supporting block 62 is lowered to the second tile supporting position to support the second mahjong tile sent out by the feeding device, and the second mahjong tile is stacked on the first mahjong tile; then, the tile supporting block 62 is raised to the pushing position, and the pushing head 63 pushes the two mahjong tiles stacked on each other out of the tile supporting block 62; the tile supporting block 62 is lowered to reset to the first tile supporting position; and the pushing head 63 is also reset and waits for the next time of stacking and pushing. The pushing position of the tile supporting block 62 is at least two mahjong tile thicknesses higher than the second tile supporting position.

[0070] In the utility model, the tile supporting block 62 of the pushing device 6 is arranged outside the shuffling frame, therefore, the feeding opening of the feeding device 5 and the feeding opening of the flat pushing and feeding device 7 are also arranged outside the shuffling frame. In this way, the shuffling space is not occupied when the tile supporting block is lowered, so that the shuffling frame and the shuffling large disc can be maximized.

[0071] In an embodiment of the utility model, the tile supporting plate can adopt the prior art disclosed in the patent documents with the publication number CN117982871A and the like:

[0072] The upper card seat 70 of the flat pushing upper card device 7 is hollowed out close to the inner side wall part of the shuffling large disc, or is hollowed out entirely, so that the edge of the shuffling large disc 2 can expand to be directly below the card receiving plate 72, and the card feeding motor 51 of the card feeding device 5 can also extend to be directly below the card receiving plate 72. In this way, most of the card receiving plate 74 and a small part of the card receiving plate 72 are located above the shuffling frame, and the card feeding outlet of the card feeding device 5 and the card receiving block 62 of the pushing card device 6 are located directly below the card receiving plate 74, which not only effectively increases the shuffling space while increasing the size of the shuffling large disc, but also shortens the length of the card feeding channel of the card feeding device 5, so that the position of the card receiving block 62 of the pushing card device 6 and the card feeding inlet of the flat pushing upper card device 7 is more reasonable; the interference and limitation of the flat pushing upper card device and the card feeding device on the shuffling large disc and the shuffling space are reduced, so that the shuffling frame and the shuffling large disc can be maximized, and the shuffling large disc and the shuffling space are increased without increasing the thickness of the mahjong machine on the same size mahjong machine bottom plate, for example, 108 pieces of 62 mahjong shuffling arrangement is realized on a 36 table mahjong machine. However, from Figure 1 It can be seen that the inner side upper card guide shaft 706 of the card receiving plate 74 is still located outside the shuffling large disc 2. In the prior art, the inner and outer upper card guide shafts of the card receiving plate are fixed on the bottom of the card receiving plate, and when the card receiving plate is lowered, the lower end of the inner side upper card guide shaft approaches or even needs to pass through the bottom plate, thereby limiting the outward expansion of the shuffling large disc and affecting the further increase of the shuffling space.

[0073] Therefore, in the preferred embodiment of the utility model, as shown in Figure 2 The inner side upper card guide shaft 706 of the card receiving plate 74 is arranged above the inner side of the outer circumference of the shuffling large disc 2, and is fixedly connected or integrally formed on the upper card seat 70, the integral shuffling barrel 4 or the card feeding seat 53. The inner side upper card guide sleeve 740 is sleeved on the inner side upper card guide shaft 706, and the inner side upper card guide sleeve 740 is fixedly connected with the card receiving plate 74. In this way, the length of the inner side upper card guide shaft 706 only needs to be slightly greater than the lifting height of the card receiving plate 74, and will not extend downward into the shuffling space to affect shuffling. Therefore, the card receiving plate can be further pushed inward and does not interfere with the shuffling space, so that the card receiving plate is not limited by the shuffling frame (shuffling barrel) in terms of the edge distance, thereby realizing that a larger shuffling large disc can be selected for the same card receiving plate edge distance, a larger shuffling large disc can shuffle more cards, and more players can be satisfied. For example, 120 pieces of 64 mahjong shuffling arrangement can be realized on a 36 table mahjong machine, and the minimum card receiving plate edge distance can be 290 mm.

[0074] In the embodiment, the inner end of the upper tile seat 70 is provided with an extension arm 705, and the inner tile guide shaft 706 of the tile supporting plate 74 is fixedly arranged on the extension arm 705. The upper tile seat 70 is provided with a tile guide shaft seat 704 on the outer side of the upper tile seat 70, and the outer tile guide shaft 741 of the tile supporting plate 74 is slidingly arranged in the tile guide shaft seat 704. In this way, the load-bearing structure of the tile supporting plate is more balanced, the inner and outer sides of the tile supporting plate are both positioned on the upper tile seat, the installation and debugging are more convenient, and the lifting movement is more stable and reliable.

[0075] In the embodiment, the inner end of the upper tile seat 70 is provided with an extension arm 705, and the inner tile guide shaft 706 of the tile supporting plate 74 is fixedly arranged on the extension arm 705. The upper tile seat 70 is provided with a tile guide shaft seat 704 on the outer side of the upper tile seat 70, and the outer tile guide shaft 741 of the tile supporting plate 74 is slidingly arranged in the tile guide shaft seat 704. In this way, the load-bearing structure of the tile supporting plate is more balanced, the inner and outer sides of the tile supporting plate are both positioned on the upper tile seat, the installation and debugging are more convenient, and the lifting movement is more stable and reliable.

[0076] In other embodiments, the inner tile guide shaft 706 of the tile supporting plate 74 can also be arranged on the front side of the length side of the tile supporting plate 74, that is, between the tile supporting plate 74 and the central lifting device of the mahjong machine (between the tile supporting plate and the tile feeding hole of the tile shuffler). Such a structure is particularly suitable for the case where the inner tile guide shaft of the tile supporting plate is fixedly arranged on the tile shuffler, and the overall structure is more simple and reasonable.

[0077] In an embodiment of the present application, the upper tile seat can adopt the prior art disclosed in the patent document with the publication number CN117982871A:

[0078] The upper card seat is no longer provided with a front side wall on the front side close to the shuffling frame, so that the internal space (the space below the card receiving plate) of the upper card seat becomes an open space, so that the mahjong shuffling tray / shuffling frame and the card feeding motor can extend into the open space, and the upper card seat becomes an open seat structure formed by the rear side wall, the top wall and the left and right side walls. The top wall of the upper card seat is used to form a fixed and non-lifting card receiving plate. Because the top wall is fixed, the thickness is relatively thin, the shuffling frame is arranged below the top wall, and the height difference between the card outlet position of the card feeding device and the lowest position of the card receiving plate is not increased, and the thickness of the mahjong machine is not increased. Compared with the bottom hollow structure disclosed in the patent documents with publication numbers CN109794059A and the like, it is more reasonable. The rear side wall of the upper card seat is used to mount the flat push card feeding motor 71 and the card feeding transmission mechanism. In order to reduce the volume occupied by the card feeding transmission mechanism in the open space (the space below the card receiving plate), the rear side wall is preferably provided in a rear protruding manner, so that a plurality of recesses for accommodating part of the components in the card feeding transmission mechanism are formed in front of the rear side wall. The left and right side walls of the upper card seat are used to fixedly connect the card guiding shaft seats. In order to increase the overall strength of the upper card seat and facilitate injection molding, a bottom wall is further provided. However, the bottom wall can be hollowed out at the interference position of the mahjong shuffling tray and the card feeding motor to avoid affecting the arrangement of the two. However, in the structure, the top wall of the upper card seat is a thin-walled structure with a relatively long length, so that the structural strength and bearing capacity are poor, and the guide shaft seat inside the upper card seat and the side wall structure connected thereto also limit the arrangement and maintenance and disassembly of the washing space and the card feeding device.

[0079] Therefore, in the preferred embodiment of the utility model, as Figure 6 、 Figure 16 and Figure 17As shown, the upper tile seat 70 includes an upper tile seat body 701 mounted on the bottom plate 1, the upper tile motor 71 and the upper tile driving mechanism for driving the tile pushing plate 73 to translate and the tile supporting plate 74 to lift the upper tile are all mounted on the upper tile seat body 701, the top wall of the forward extension of the upper tile seat body 701 forms part of the tile supporting plate 72, the inner side of the upper tile seat body 701 is provided with a cantilever part 707 extending forward, the cantilever part 707 is hollowed out below, the top of the cantilever part 707 forms part of the tile supporting plate 72, the tile pushing seat is arranged at the rear side of the cantilever part 707 and is fixedly connected with the cantilever part 707 and the upper tile seat body 701 respectively, so as to form a reinforced support for the cantilever part 707, the inner side end of the cantilever part 707 is provided with an extension arm 705 extending forward, the inner side tile guide shaft 706 of the tile supporting plate 74 is fixedly arranged on the extension arm 705, the inner side tile guide sleeve 740 is sleeved on the inner side tile guide shaft 706, and the inner side tile guide sleeve 740 is fixedly connected with the tile supporting plate 74. The outer side of the upper tile seat body 701 is provided with an upper tile guide shaft seat 704 extending forward, the outer side tile guide shaft 741 of the tile supporting plate 74 is arranged in the upper tile guide shaft seat 704, and the outer side tile guide shaft 741 is fixed on the bottom of the tile supporting plate 74 and synchronously lifts and lowers with the tile supporting plate 74. In this way, the cantilever part and the extension arm are hollowed out to avoid the upper tile seat from occupying the shuffling space, the tile pushing seat is fixedly connected with the upper tile seat body and the cantilever part to strengthen the structural strength and bearing capacity of the cantilever part, the upper tile motor and the upper tile driving mechanism are all mounted on the upper tile seat body at the periphery of the shuffling barrel to avoid them from occupying the shuffling space, the structure is reasonable and does not affect each other, and the disassembly, assembly and maintenance are convenient.

[0080] In other embodiments, the outer side tile guide shaft 741 of the tile supporting plate 74 can also be fixed on the upper tile seat 70, an outer side tile guide sleeve is sleeved on the outer side tile guide shaft 741, and the outer side tile guide sleeve is fixed on the bottom of the tile supporting plate 74 and synchronously lifts and lowers with the tile supporting plate 74.

[0081] In this embodiment, the outer side end of the upper tile seat 70 is provided with an extension part 703, the extension part 703, the cantilever part 707 and the top wall of the forward extension of the upper tile seat body 701 jointly form the tile supporting plate 72, and the outer side end of the extension part 703 is fixedly connected or integrally formed with a side baffle 721 for blocking mahjong tiles. In this way, the length of the top thin wall structure of the upper tile seat can be avoided from being too long to affect the structural strength and bearing capacity, and the extension part is arranged to make the tile pushing and lifting device have better universality, and suitable extension parts can be replaced according to the use requirements of mahjong machines of different specifications, without the need to replace the entire tile pushing and lifting device, thereby reducing the mold opening cost and the inventory cost.

[0082] In this embodiment, the upper tile seat body 701, the extension part 703, the cantilever part 707 and the extension arm 705 all adopt a grid-shaped reinforcing structure to increase the structural strength and bearing capacity thereof.

[0083] Preferably, the top wall of the upper card seat body 701 extends forward and is provided with an upper and lower through opening. The lower part of the opening is provided with a card feeding motor 51 of the card feeding device 5. A detachable plate 702 is fixed in the opening. The top part of the detachable plate 702 forms part of the card receiving plate 72. In this way, when the card feeding device is disassembled from the mahjong tile shuffling barrel, the detachable plate can be disassembled first to form an opening through which the card feeding motor can pass from bottom to top. Then the card feeding device is disassembled. The card feeding device can be taken out without disassembling the surrounding flat push card feeding device. The maintenance and disassembly are very convenient.

[0084] Further preferably, the upper card seat 70 is provided with a card pushing frame 731. The opening is located in front of the card pushing frame 731. In this way, the card feeding motor 51 can be installed close to the tile suction wheel 52 or directly drive the tile suction wheel 52. The card feeding device is shorter and more convenient to maintain and disassemble.

[0085] Preferably, the bottom of the upper card seat body 701 is provided with a first upper card mounting foot 7011 for fixedly connecting to the whole mahjong tile shuffling barrel and a second upper card mounting foot 7012 for fixedly connecting to the bottom plate 1. In this way, the upper card seat is positioned and fixed on the whole mahjong tile shuffling barrel and the bottom plate. The whole mahjong machine core is more convenient to position and install. The whole connection structure is more reasonable and has higher strength.

[0086] In an embodiment of the utility model, the setting of the card supporting plate transmission mechanism can adopt the prior art disclosed in patent documents such as CN109381855A, CN112023390A, CN114247127A, CN114146397A and CN117982871A, and the card supporting plate transmission mechanism comprises: card feeding curve cams, two card feeding curve cams are respectively installed on the left and right sides of the bottom of the card supporting plate, the left and right ends of the bottom of the card supporting plate are slidably connected with the upper card seat through two guide shafts or sliding sleeves; card feeding rocker arms, two card feeding rocker arms are respectively movably connected with the two card feeding curve cams; card feeding rocker shafts, the card feeding rocker shafts are rotatably installed on the upper card seat, and the two card feeding rocker arms are respectively fixed on the two card feeding rocker shafts; a card feeding driving cam, the card feeding driving cam is installed on the upper card seat and is driven to rotate by a card feeding motor; a card feeding connecting rod, the card feeding connecting rod is driven to move by the card feeding driving cam; the card feeding connecting rod drives the two card feeding rocker shafts to synchronously rotate, so that the card supporting plate is driven to move up and down by driving the two card feeding rocker arms to rotate. In this way, the volume of the card feeding curve cam is small, the installation position of the card feeding rocker arm is high, and the card feeding rocker arm is intermittently swung, the card feeding rocker shaft is extended forward to suspend and set the card feeding rocker arm, the card feeding connecting rod and the card feeding driving cam are arranged more rearward, the card supporting plate transmission mechanism occupies less shuffling space, the diameter of the shuffling disc can be increased, the shuffling space is increased, the shuffling efficiency is improved, and the probability of mutual impact of mahjong tiles on the shuffling disc is reduced, so that the shuffling noise is reduced. However, the suspension of the card feeding rocker shaft and the cam connecting rod driving mechanism leads to insufficient support strength and weak bearing capacity of the card supporting plate, the connecting rod is prone to blockage, the two card feeding rocker arms are unevenly stressed, the synchronization is poor, and the installation and maintenance and debugging are difficult.

[0087] Therefore, in the preferred embodiment of the utility model, as shown in Figures 9 to 15 The card supporting plate transmission mechanism comprises:

[0088] Two card feeding curve cams 744, the two card feeding curve cams 744 are respectively installed on the left and right sides of the bottom of the card supporting plate 74;

[0092] Two first gears 748 are rotatably installed on the upper card seat 70, and the first gears 748 are driven synchronously by the flat pushing upper card motor 71 through the cooperation of the cranks 747 and the upper card arm cam 746.

[0093] In this way, the cam is installed on the upper card arm shaft and is driven by the cooperation of the crank gear, the transmission torque is large, the stability and synchronism are better, the installation and debugging are more convenient, and the maintenance and disassembly are also more convenient.

Such a gear transmission mechanism has a reasonable structure, smooth movement, large transmission torque, and is also more convenient to install and maintain.

[0095] The preferred embodiment of the present application is that during the lifting of the card supporting plate 74, the two upper card arms 743 are synchronously rotated in opposite directions, and the two first gears 748 are synchronously rotated in opposite directions. In this way, the lifting structure of the card supporting plate 74 is reasonable and the movement is smooth.

[0096] The preferred embodiment of the present application is that the crank 747 is driven by the cooperation of the roller and the cam groove 7461 on the upper card arm cam 746, and the crank 747 is fixedly connected or integrally formed with the first gear 748. In other embodiments, the crank gear can also not highlight the shape of the crank, but a roller or a column for cooperating with the cam groove is installed at the eccentric position of the first gear to form a virtual crank gear transmission structure.

[0097] The preferred embodiment of the present application is that the upper card arm 743, the upper card arm shaft seat 7451 and the upper card arm cam 746 are sequentially sleeved on the upper card arm shaft 745 from front to back. In this way, not only can the space for shuffling cards be reduced, but also the transmission structure is more stable and reliable.

[0098] The preferred embodiment of the present application is that the front end of the upper card arm shaft 745 is fixedly connected or integrally formed with the upper card arm 743, the rear end of the upper card arm shaft 745 is installed on the upper card seat main body 701 through a bearing, and the upper card arm cam 746 is fixedly connected or integrally formed with the upper card arm shaft 745.

[0099] The preferred embodiment of the present application is that the bottom of one of the upper card arm shaft seats 7451 on the upper card seat 70 near the card storage channel card inlet is supported by the shuffling barrel, and the bottom of the other upper card arm shaft seat 7451 is supported by the support column 75, and the support column 75 is fixedly connected or integrally formed with the upper card seat 70. In this way, the support strength and bearing capacity of the card supporting plate can be maximized.

[0100] In this embodiment, the upper card shaking arm shaft seat 7451 is preferably composed of two parts, the upper half of the upper card shaking arm shaft seat 7451 is fixed to the front side of the upper card seat 70 by horizontal fasteners, and the upper and lower parts of the upper card shaking arm shaft seat 7451 are fixed and connected together by vertical fasteners.

[0101] In this embodiment, the pushing plate transmission mechanism preferably includes a pushing frame 731, a pushing sliding block 7311, a pushing cam 732, and a pushing swing lever 734, the pushing sliding block 7311 slides back and forth on the pushing frame 731 along a guide rod, the pushing plate 73 is fixed to the pushing sliding block 7311, the upper end of the pushing swing lever 734 is movably connected to the pushing sliding block 7311, the lower end of the pushing swing lever 734 is hinged to the upper card seat 70 through a pushing swing lever shaft 735, the pushing swing lever shaft 735 is fixed with a pushing swing arm 733, the swinging end of the pushing swing arm 733 is movably connected to the pushing cam 732 through a roller, one second gear 749 is driven to rotate by the pushing upper card motor 71, and the other second gear 749 is coaxially fixed and synchronously rotates with the pushing cam 732, so that the pushing upper card motor 71 drives the pushing sliding block 7311 to slide back and forth through the pushing cam 732 and the pushing swing lever 734 to implement pushing of the card. Further preferably, the pushing swing arm 733 is arranged between the pushing upper card motor 71 and the pushing cam 732. Further preferably, a pushing cover plate 736 is fixedly arranged above the pushing plate 73. In other embodiments, the card supporting plate transmission mechanism and the pushing plate transmission mechanism can also refer to various embodiments disclosed in patent documents with publication numbers CN109381855A, CN109794059A, CN112023390A, CN114247127A, CN114146397A, CN117982871A, etc.

[0102] In this embodiment, as shown in Figure 21 There is a gap C between the card supporting plate 72 and the card supporting plate 74, the width of the gap C is less than one third of the length of the mahjong tile, and when the card supporting plate 74 is lowered to the bottom, the top supporting plane of the card supporting plate 74 is not higher than the tile 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 positions of the card supporting block in the pushing device and the card supporting plate in the pushing upper card device are not adjusted), so that the distance between the card supporting plates can be further reduced. Further 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 tile storage plane of the card supporting plate 72 is 0.5 to 1.5 mm.

[0103] In other embodiments, a transition plate can also be provided between the supporting plate and the supporting plate, and the mahjong tiles on the supporting plate are pushed to the supporting plate through the transition plate when the pushing plate pushes the mahjong tiles. In this way, the position of the supporting plate can be pushed more inwardly so as to push the four mahjong tile walls inwardly, and the distance between the supporting plates is minimized. The specific setting of the transition plate can refer to various embodiments disclosed in patent documents with publication numbers CN114146396A, CN114146398A and the like.

[0104] The action process of the flat pushing mahjong device is preferably as follows:

[0105] As shown in Figures 9 to 12 , the supporting plate 74 is in the raised state, the flat pushing mahjong motor 71 drives the crank gear 748 to rotate by 75-110 degrees, and the supporting plate 74 moves from the high point to the low point to receive the mahjong, as shown in Figure 13 and Figure 14 , the crank gear 748 continues to rotate by 80-125 degrees, the pushing plate 73 pushes the mahjong tiles on the supporting plate 72 onto the supporting plate 74, the crank gear 748 continues to rotate by 105-160 degrees, and the supporting plate 74 is raised to the tabletop to play mahjong. The whole process is repeated.

[0106] When the pushing plate pushes the mahjong tile wall on the supporting plate to the supporting plate, in order to avoid the mahjong tiles being pushed out of the supporting plate by the pushing plate and falling into the mahjong tray or being stuck, a tile blocking frame is preferably provided on the inner side of the four supporting plates, which is used to prevent the mahjong tile wall on the supporting plate from moving inwardly.

[0107] The flat push blocking structure can adopt the existing technology disclosed in patent documents CN112023390A, CN117982870A, CN114247127A, CN114146397A, CN117982871A, CN219149199U, etc. The blocking frame extends outwardly with an outer blocking part to match the length of each side tile plate, and blocks the mahjong tiles on the tile plate from moving inward from the inner side of the tile plate, thereby ensuring the uniformity of the mahjong tile wall pushed onto the tile plate. Because in the fixed tile plate windmill-shaped mahjong machine structure, the tile pushing head of the tile pushing device moves at a relatively high position, which is higher than the height of the tile plate of the flat push tile device, which causes the tile pushing head of the tile pushing device to interfere with the outer blocking part of the adjacent side blocking frame. Therefore, in a preferred embodiment, the outer blocking part of the adjacent side blocking frame is provided with an opening above the tile block of the tile pushing device to avoid affecting the tile pushing head of the tile pushing device, and the tile pushing head is stopped at a suitable position to realize the flat push blocking function together with the blocking frame and its outer blocking part. However, because the tile pushing head is an active component, its stopping position is not extremely accurate (otherwise the cost will be high), it is difficult to ensure that the back side of the tile pushing head is flush with the blocking frame and its outer blocking part, and the tile pushing head also has unavoidable looseness caused by transmission gap, so in actual use, there is often a problem that the mahjong tile wall pushed onto the tile plate is not uniform.

[0108] To solve the above problems, one embodiment is to install a blocking plate on the back side of the tile pushing head, which can move relative to the tile pushing head (relatively small movement range), and the blocking plate moves together with the tile pushing head during tile pushing by the tile pushing device. The blocking plate can be positioned and fixed with the tile plate during flat push tile by the flat push tile device, so that it is flush with the blocking frame and its outer blocking part, blocks the mahjong tiles on the tile plate from moving inward from the inner side of the tile plate, and realizes the flat push blocking function, thereby ensuring the uniformity of the mahjong tile wall pushed onto the tile plate. In this way, by setting a blocking plate movable relative to the tile pushing head, the blocking plate is positioned and fixed by the tile plate during flat push tile to ensure that it is flush with the blocking frame and its outer blocking part, thereby overcoming the defect that the tile pushing head cannot be relatively positioned and easily loosened during flat push blocking. Another embodiment is that the flat push blocking mechanism includes a blocking frame for blocking the mahjong tiles on the tile plate of the flat push tile device from moving inward, the blocking frame is located on the inner side of the tile plate, and the blocking frame extends outwardly with an outer blocking part; the outer blocking part is provided with an opening above the tile block of the tile pushing device for the tile pushing head of the tile pushing device to move through; and further includes a movable blocking plate, which is installed on the outer blocking part in a way that it can be flipped and swung up and down, and is driven by the tile pushing head or the tile plate to flip and swing up and down, and is reset by a elastic member.

[0109] The above-mentioned signboard frame and the outer signboard part can be two or more components which are directly fixedly connected or indirectly fixedly connected through other intermediate components. In other preferred embodiments, the signboard frame and the outer signboard part thereof can be integrally formed.

[0110] In this embodiment, a flat push signboard structure is preferably provided, as shown in Figure 20 The four signboard frames are integrally connected to form a square signboard cover 8. Each of the four outer signboard parts includes an inner part, i.e., an inner signboard plate 54, and an outer part, i.e., an outer signboard plate 9. An opening is provided between the inner signboard plate 54 and the outer signboard plate 9 for the pusher head 63 to pass through. An active baffle 92 is provided in the opening. The active baffle 92 is installed on the mahjong machine tabletop in a manner that it can be flipped up and down and is reset by a resilient member. The outer signboard plate 9 is a separate component which is directly fixed on the mahjong machine bottom plate. The inner signboard plate 54 can be a separate component which is fixed on the signboard cover 8, the integral mahjong shuffling barrel 4, or the tile feeding seat 53, or can be integrally formed with the signboard cover 8, the integral mahjong shuffling barrel 4, or the tile feeding seat 53.

[0111] In this embodiment, the inner signboard plate 54 is fixedly connected to or integrally formed with the tile feeding seat 53. This facilitates the maintenance and disassembly of the tile feeding device. As shown in Figure 22 and Figure 23 The inner signboard plate 54 is integrally formed with the inner housing 532 of the tile feeding seat 53.

[0112] In this embodiment, as shown in Figure 5 and Figure 20 A signboard block 64 is provided outside the tile outlet of the tile feeding device 5, and a tile feeding side blocking part 5311 is provided on the tile feeding seat 53. When the tile receiving block 62 receives the mahjong tiles fed by the tile feeding device 5, the signboard block 64 and the tile outlet of the tile feeding device are located on opposite sides of the tile receiving block 62, and the tile feeding side blocking part 5311 and the pusher seat 65 / upper tile seat 70 (cantilever part 707) are located on the other opposite sides of the tile receiving block 62. This not only avoids the mahjong tiles from falling into the space outside the tile receiving block and causing failure, but also makes the structure more reasonable and reliable.

[0113] In this embodiment, as shown in Figure 2 and Figure 5As shown, in the same group of card picking and carrying system, the angle A between the length side of the card supporting plate 74 and the card feeding 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 feeding direction of the card feeding device 5 is 75°-85°; the inner side card blocking plate 54 is pressed above the card feeding opening of the card feeding channel, and the maximum distance between the outer side end of the inner side card blocking plate 54 and the inner side end of the card pushing head 63 is less than the width of a mahjong tile. In this way, not only the angle between the tile suction wheel of the conveying device and the large mahjong tile washing disc is more reasonable, the mahjong tile washing space is larger, and the mahjong tile picking efficiency is higher, but also the mahjong tiles can be prevented from being pushed to the upper side of the card feeding seat when the tile receiving block receives the tiles and the card pushing head pushes the tiles, thereby avoiding the failure caused by the adjustment of the angle of the mahjong tiles.

[0114] Preferably, in the embodiment, the angle between the card blocking surface of the tile receiving block 64 facing the card feeding opening of the card feeding device 5 and the card feeding direction of the card feeding device 5 is 85°-89°, and the angle between the card blocking surface of the tile receiving block 64 and the tile feeding direction of the tile storage channel is 5°-10°. In this way, the angle position of the mahjong tile on the tile receiving block is closer to the tile feeding direction of the tile storage channel, and the adjustment of the angle of the mahjong tile when the card pushing head pushes the tiles is avoided, thereby preventing the pushing of the tiles from being blocked or the mahjong tiles from being pushed to jump.

[0115] Preferably, in the embodiment, a card pushing and guiding structure is arranged, as shown in Figure 5 and Figure 20 As shown, the outer side card blocking plate 9 is provided with a card guiding piece 91 near the opening, the card guiding piece 91 is embedded in the outer side card blocking plate 91 and is fixed by fasteners, the inner side end of the card guiding piece 91 extends into the opening and is provided with an outer side card guiding surface 911 for contacting the mahjong tile, the outer side end of the inner side card blocking plate 54 is provided with an inner side card guiding surface 541 for contacting the mahjong tile, the pushing path of the card pushing head 63 is located between the outer side card guiding surface 911 and the inner side card guiding surface 541, the outer side card guiding surface 911 and the inner side card guiding surface 541 are oppositely arranged and form a horn shape from large to small along the pushing direction of the card pushing head, thereby guiding the mahjong tile to the tile feeding opening of the tile storage channel when the card pushing head pushes the tiles. In this way, the angle and direction of the mahjong tile can be adjusted by the horn during the pushing process of the card pushing head, so that the angle and direction of the mahjong tile entering the tile storage channel of the flat pushing and carrying device are consistent with the direction of the length side of the card supporting plate, and the mahjong tiles are arranged in order.

[0116] Preferably, in the embodiment, the angle between the outer side card guiding surface 911 of the card guiding piece 91 and the tile feeding direction of the tile storage channel is 5°-10°, and the angle between the inner side card guiding surface 541 of the inner side card blocking plate 54 and the tile feeding direction of the tile storage channel is 5°-10°.

[0117] The top of the stopper block 64 preferably extends into the opening and is formed with a flat push stopper surface flush with the outer stopper plate 9 for flat pushing of the stopper and a push stopper guide surface cooperating with the stopper guide 91 for guiding the stopper. The gap between the stopper block 64 and the stopper guide 91 above it and the gap between the stopper block 64 and the outer stopper plate 9 outside it can allow the connecting arm 631 of the push head 63 to pass through. Thus, the action structure is simple and reasonable.

[0118] The stopper block 64 is preferably adjustably fixed on the push seat, and the stopper guide 91 is adjustably fixed on the outer stopper plate 9. Thus, by adjusting the installation positions of the stopper block and the stopper guide, different sizes of mahjong tiles can be adapted. In other embodiments, the stopper block 64 can be fixedly connected or integrally formed with the push seat or the outer stopper plate, and the stopper guide 91 can be fixedly connected or integrally formed with the outer stopper plate 9.

[0119] In an embodiment of the utility model, the shuffling barrel can adopt the prior art disclosed in patent documents with publication number CN117982871A and the like: two adjacent tile feeding devices 5 are connected and transitioned through a connecting wall, four tile feeding devices 5 in four tile picking and carrying systems are connected head to tail through four connecting walls to form a shuffling frame (a shuffling space is inside the shuffling frame), the shuffling frame is arranged around the shuffling tray 2, the tile feeding port of the tile feeding device 5 is located on the inner side wall of the shuffling frame, the tile feeding port of the tile feeding device 5 is located on the outer side of the shuffling frame, and four tile 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, the splicing and installation are complicated, the overall strength of the shuffling frame is poor, the installation and positioning accuracy is low, a lot of space is occupied, and the tile feeding device is also very inconvenient to disassemble, maintain and repair.

[0120] Therefore, in the preferred embodiment of the utility model, a whole shuffling barrel integrally injection molded is adopted, such as Figure 3 、 Figure 6 、 Figure 18 and Figure 19As shown, the four sets of card feeding devices 5 of the card picking and carrying system are all installed on a whole shuffling barrel 4, which covers the shuffling tray 2 and is fixed on the bottom plate 1. The top of the whole shuffling barrel is a square mounting table 42, the center of which is a card placing hole 41. The bottom of the whole shuffling barrel is a mounting ring 46 in the shape of a circle, the outer diameter of which is larger than that of the square mounting table 42. The square mounting table 42 is connected with the mounting ring 46 through four barrel walls. Adjacent two barrel walls are provided with a card feeding mounting opening 47 for installing the card feeding device. Each barrel wall is formed with a card supporting plate step 43 and a card receiving plate step 44. 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 (i.e. similar to the height of the front baffle 742, generally 25-55 mm). The card supporting plate step 43 is located below the card supporting plate 74 in the flat pushing card feeding device, and the card receiving plate step 44 is located below the card receiving plate 72 in the flat pushing card feeding device.

[0121] In this way, the whole shuffling barrel has fewer parts and is easier to install than the shuffling frame assembled by four square card feeding devices. The card feeding device can be made shorter, and the barrel wall is thin-walled, which is easy to form, avoid structure and occupy less space. The internal shuffling space is large, and the whole shuffling barrel has better stress strength and is not easy to deform. It is convenient to install, position and debug, and the card feeding seat, the pushing card seat and the card feeding seat are easy to position, install and support.

[0122] As shown in Figure 18 and Figure 19 Each barrel wall is provided with a card guiding step 45 on the side close to the card feeding mounting opening 47. The card guiding step 45 is located between the card receiving plate step 44 and the mounting ring 46 and on the side of each barrel wall close to the card feeding opening of the card receiving channel. In this way, the shuffling space in the shuffling barrel can form a card guiding space between the shuffling tray and the card guiding step to limit the height of the mahjong tiles entering the lower part of the card suction wheel, avoid the card suction wheel from being blocked and improve the shuffling efficiency.

[0123] The square mounting table 42 is provided with a ventilation opening 421, and a fan 422 is installed on the ventilation opening 421. In this way, it is convenient to ventilate, dehumidify and deodorize the shuffling space.

[0124] The square mounting table 42 is provided with a card blocking cover 8, which is fixedly connected with or integrally formed with the square mounting table 42 and located on the inner side of the card supporting plate step 43. In this way, the card blocking cover not only prevents the mahjong tiles from falling, but also effectively supports the table top. The shuffling barrel and the card blocking cover 8 are separately formed and then fixedly connected, which is also convenient for the installation and maintenance of the fan, the circuit board and the like on the square mounting table 42.

[0125] The upper card feeding arm avoiding groove 431 is arranged on the card supporting plate step 43 to accommodate the upper card feeding arm 743 and the upper card feeding cam 744 in the flat pushing card feeding device. When the card supporting plate 74 is lowered, the upper card feeding arm avoiding groove 431 can accommodate the upper card feeding arm 743 and the upper card feeding cam 744, so that the card supporting plate step 43 can provide good support for the card supporting plate 74, and the card supporting plate step 43 is easy to be formed and occupies less space.

[0126] The avoiding groove 432 or the avoiding hole is arranged at one end of the card supporting plate step 43 to accommodate the extension arm 705 in the flat pushing card feeding device. Thus, the extension arm 705 on the upper card seat 70 can be inserted into the avoiding groove 432 or the avoiding hole, so that the extension arm 705 can avoid interference with each other, and positioning cooperation and reliable support can be formed.

[0127] In other embodiments, the inner side upper card guide shaft 706 of the card supporting plate 74 can be fixed on the card supporting plate step 43 of the shuffler. Thus, the extension arm 705 on the upper card seat 70 can not be arranged, so that the structure is simplified and easy to be formed.

[0128] The upper card feeding arm shaft seat support 441 for supporting the upper card feeding arm shaft 745 in the flat pushing card feeding device and the cantilever part support 442 for supporting the cantilever part 707 in the flat pushing card feeding device are arranged on the card receiving plate step 44. Thus, the shuffler can provide reliable support for the upper card feeding arm shaft 745 and the cantilever part 707 on the upper card seat 70, so that the supporting strength of the card receiving plate and the card supporting plate and the weight that can be supported are increased.

[0129] The pushing seat support 461 for supporting the pushing seat 65 in the pushing card device 6 and the upper card seat support 462 for supporting the upper card seat 70 in the flat pushing card feeding device 7 are arranged on the mounting ring 46. Thus, the pushing seat 65 in the pushing card device 6 is supported by the pushing seat support 461 and fixed on the shuffler and the bottom plate by fasteners, the upper card seat 70 in the flat pushing card feeding device 7 is supported by the upper card seat support 462 and fixed on the shuffler and the bottom plate by fasteners, and the inner and outer sides of the pushing seat 65 and the upper card seat 70 are leveled by the support pads, so that positioning, installation and debugging are facilitated.

[0130] The pushing seat support 461 for supporting the pushing seat 65 in the pushing card device 6 and the upper card seat support 462 for supporting the upper card seat 70 in the flat pushing card feeding device 7 are arranged on the mounting ring 46. Thus, the pushing seat 65 in the pushing card device 6 is supported by the pushing seat support 461 and fixed on the shuffler and the bottom plate by fasteners, the upper card seat 70 in the flat pushing card feeding device 7 is supported by the upper card seat support 462 and fixed on the shuffler and the bottom plate by fasteners, and the inner and outer sides of the pushing seat 65 and the upper card seat 70 are leveled by the support pads, so that positioning, installation and debugging are facilitated. Figure 3 Figure 18 As shown in FIGS. 1, 2 and 3, the card feeding installation opening 47 penetrates downward from the card supporting plate step 43 to the mounting ring 46, the inner side end of the card feeding seat 53 is fixedly installed at the card supporting plate step 43, the outer side of the card feeding seat 53 is rested on the mounting ring 46 and the card guide step 45 and fixed by fasteners, the card sucking wheel 52 is located above the card feeding installation opening 47, and the card feeding motor 51 is located outside the card supporting plate step 43. Thus, the installation screws of the card feeding device 5 are all vertical, and the card feeding device 5 is very convenient to disassemble and assemble.

[0131] The card feeding installation opening 47 penetrates downward from the card supporting plate step 43 to the mounting ring 46, the inner side end of the card feeding seat 53 is fixedly installed at the card supporting plate step 43, the outer side of the card feeding seat 53 is rested on the mounting ring 46 and the card guide step 45 and fixed by fasteners, the card sucking wheel 52 is located above the card feeding installation opening 47, and the card feeding motor 51 is located outside the card supporting plate step 43. Thus, the installation screws of the card feeding device 5 are all vertical, and the card feeding device 5 is very convenient to disassemble and assemble. Figure 22 ​and Figure 23 As shown, the card delivery holder 53 includes an outer shell 531 and an inner shell 532 that are fixedly connected as one unit. A card delivery channel is provided between the two. The outer shell 531 extends beyond the card outlet of the card delivery channel to form a card delivery side stop 5311. The outer shell 531 rests on the mounting ring 46 and is fixedly connected. The inner shell 532 rests on the card guide step 45 and is fixedly connected to the overall shuffling barrel.

[0132] Example 2:

[0133] This embodiment discloses a mahjong machine, which differs from Embodiment 1 only in the transmission mechanism of the card-supporting plate of the flat-push card-feeding device. The specific details are as follows:

[0134] like Figure 25 and Figure 26 The card-holding plate transmission mechanism shown includes two card-holding curved cams 744, two card-holding rocker arms 743, two card-holding rocker arm shafts 745, two card-holding connecting rods 762, two card-holding swing arms 764, and a card-holding drive cam 761. The two card-holding curved cams 744 are respectively installed on the left and right sides of the bottom of the card-holding plate 74, and the card-holding plate 74 is slidably connected to the card-holding seat 70. The two card-holding rocker arms 743 move in coordination with the two card-holding curved cams 744. The card-holding rocker arm shafts 745 and 762 are connected in a sliding manner with the card-holding plate 744. 5 is rotatably mounted on the card holder 70, and two card-mounting rocker arms 743 are respectively fixed on two card-mounting rocker arm shafts 745; the card-mounting drive cam 761 is mounted on the card holder 70 and driven to rotate by the flat-push card-mounting motor 71; the card-mounting connecting rod 762 is driven to move by the card-mounting drive cam 761; the card-mounting connecting rod 762 drives the card-mounting rocker arm shaft 745 to rotate through the card-mounting swing arm 764, thereby driving the two card-mounting rocker arms 743 to rotate and drive the card-supporting plate 74 to rise and fall.

[0135] In this way, the volume of the card-laying curve cam 744 is relatively small, the card-laying rocker arm 743 is installed at a higher position and adopts intermittent swinging, and the card-laying rocker arm 743 is suspended and supported by the card-laying rocker arm shaft 745 extending forward, so that the card-laying connecting rod 762 and the card-laying drive cam 761 can be set further back. Compared with the prior art, the card-laying plate transmission mechanism of this embodiment occupies less shuffling space, can increase the diameter of the shuffling plate, and increase the shuffling space. This not only improves the shuffling efficiency, but also reduces the probability of mahjong tiles colliding with each other on the shuffling plate, thereby reducing shuffling noise.

[0136] In this preferred embodiment, the license plate drive cam 761 has cam grooves on both its front and rear sides, and the two cam grooves respectively cooperate with the two license plate connecting rods 762. This double-sided cam drives the two license plate connecting rods, resulting in better synchronization. The license plate transmission mechanism has a simple structure, compact size, and is easy to adjust. The two ends of the license plate drive camshaft are respectively supported and mounted on the license plate holder 70 and the support plate 760, with the support plate 760 fixed to the license plate holder 70.

[0137] The front end of the upper card rocker shaft 745 is fixedly connected with or integrally formed with the upper card rocker 743, the rear end of the upper card rocker shaft 745 is fixedly connected with or integrally formed with the upper card swing arm 764, and the upper card swing arm 764 is movably connected with one end of the upper card connecting rod 762. A waist-shaped hole is arranged on the upper card swing arm 764, and a roller is arranged on one end of the upper card connecting rod 762 to move in the waist-shaped hole, so as to drive the upper card swing arm 764 and the upper card rocker 743 to swing.

[0138] The upper card connecting rod 762 is sleeved with a plurality of upper card connecting rod sleeves 763, and the upper card connecting rod sleeves 763 are fixed on the upper card seat 70, so that the upper card connecting rod 762 can move linearly. The two upper card rockers 743 can rotate in the same direction, but preferably, the two upper card rockers 743 rotate in opposite directions to support the lifting of the card supporting plate 74. The upper card rocker shaft 745 is sleeved with an upper card rocker shaft seat 7451, and the upper card rocker shaft seat 7451 is fixed on the rear side wall of the upper card seat 70. The upper card connecting rod 762 moves in cooperation with the cam groove of the upper card driving cam 761 through the roller. The two upper card connecting rods 762 and the two upper card swing arms 764 are arranged opposite to each other, and the upper card driving cam 761 is arranged between them.

[0139] As shown in Figure 24 and Figure 26 The flat-pushing upper card motor 71 is in transmission connection with the second gear 749, the second gear 749 is coaxially fixed and synchronously rotated with the upper card driving cam 761 and the flat-pushing cam 732, the card pushing plate transmission mechanism is the same as that in Embodiment 1, and the other structures of the mahjong machine are the same as those in Embodiment 1.

[0140] The mahjong tile arrangement method of the mahjong machine adopts the following steps:

[0141] 1) Sending tiles; the tile sending device 5 picks up the mahjong tiles from the tile washing tray 2 and sends them to the tile pushing device 6;

[0142] 2) Stacking and pushing tiles; the tile receiving block 62 of the tile pushing device 6 receives one mahjong tile sent out by the tile sending device 5 at the first tile receiving position; the tile receiving block 62 descends to the second tile receiving position to receive another mahjong tile sent out by the tile sending device 5; the tile receiving block 62 rises to the tile pushing position, and the two stacked mahjong tiles are pushed by the tile pushing head 63 to the tile receiving plate 72 of the flat-pushing upper card device 7, and then the tile receiving block 62 and the tile pushing head 63 are reset, respectively;

[0143] 3) Repeating the above step 2) until the tile receiving plate 72 of the flat-pushing upper card device 7 stores the required multiple stacks of mahjong tiles;

[0144] 4) flat push up card; after receiving the up card instruction, the card receiving plate 74 of the flat push up card device 7 is lowered to the bottom from the table top; the pushing plate 73 pushes the multiple stacks of mahjong tiles on the receiving plate 72 to the card receiving plate 74; the card receiving plate 74 is raised to the table top.

[0145] As shown in Figure 1 The existing windmill-shaped mahjong machine (36 table top 81.5*81.5cm square) has a maximum diameter of 600mm for the tile washing large plate and effective washing space, and can only wash 108 pieces of 62 mahjong tiles. As shown in Figure 2 The same size mahjong machine core uses the structure of the present application, and the maximum diameter of the tile washing large plate and effective washing space can be 650mm, and 120 pieces of 64 mahjong tiles can be washed and arranged on the 36 table mahjong machine, and the minimum distance between the receiving plates can be 290mm.
