Description

TECHNICAL FIELD

[0001] The utility model belongs to mahjong machine manufacturing field, especially relate to a mahjong machine. 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 desktop after being lifted to the desktop, and the mahjong tiles are very close to the table edge, and the position is unreasonable, and the player needs to manually move the mahjong tiles to the appropriate position before picking up the tiles, and 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, and the flat pushing tile feeding device is inclinedly arranged relative to the side edge of the same side of the desktop panel, and the tile feeding port end of the flat pushing tile feeding device is closer to the other end, and the four mahjong tiles of the mahjong machine are lifted to the mahjong machine desktop in the form of being respectively inclined to the four edges of the mahjong machine desktop panel and being close to the center of the mahjong machine desktop panel. By inclining the flat pushing tile feeding device, the tile feeding port and the tile supporting plate corresponding to the flat pushing tile feeding device are also in an inclined state relative to the side edge of the same side of the desktop panel, and when the mahjong tile wall is lifted to the desktop 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 since the mahjong tile wall is pushed in a flat manner to the tile supporting plate and is lifted to the desktop panel from the tile supporting plate, there is no problem of tile falling. However, compared with the common four-port mahjong machine (the flat pushing tile feeding device is parallelly arranged relative to the side edge of the same side of the desktop panel), the inclined arrangement of the flat pushing tile feeding device makes the tile feeding port end closer to the center of the mahjong machine desktop panel, which affects the arrangement of the tile shuffling disc and occupies the tile shuffling space. In order to increase the size of the tile shuffling disc to play larger mahjong tiles, generally, a part of the tile supporting plate of the flat pushing tile feeding device is arranged above the tile feeding device. This results in a large height difference between the tile feeding port height of the tile feeding device and the lowest position of the tile supporting plate, which leads to too large lifting span of the tile supporting block in the tile pushing device, low tile pushing efficiency, unstable operation and easy mahjong tile disorder and card jamming.

[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, windmill-shaped mahjong machine disclosed in the aforementioned patent documents has a square tile wall that is tilted in a windmill shape, which is further outward than the square tile wall of the inclined-slope windmill-shaped mahjong machine. Generally, players still need to manually push the mahjong tile wall in a little to make it suitable for playing, which still causes inconvenience. The main reason for this is that there is interference between the flat-push tile-loading device and the shuffling tray and the tile-feeding device at the edge of the shuffling tray. This prevents the flat-push tile-loading device and its tile-supporting plate used for raising tiles from pushing further inward, otherwise it would excessively encroach on the shuffling space, significantly reducing the maximum size of the mahjong tiles that the machine can use.

[0008] To this end, patent documents with publication numbers CN117982870A, CN117982871A, and CN117982868A disclose a mahjong machine, such as... Figure 1 As shown, the dotted line indicates the flat-push card-loading device. The mahjong machine includes a large shuffling tray 2 located in the center of the machine frame base plate. Four sets of card-picking and transporting systems are arranged around the large shuffling tray 2. The card-picking and transporting system includes a card-feeding device 5, a flat-push card-loading device, and a card-pushing device. The flat-push card-loading device includes a card-bearing plate 72, a card-supporting plate 74, and a card-pushing plate 73. The card-supporting plate 74 is located inside the card-bearing plate 72, and the card-pushing plate 73 is located outside the card-bearing plate 72 and pushes the cards from the outside to the inside. One end of the card-bearing plate 72 extending along the length direction is the card inlet. A card-bearing block 62 of the card-pushing device is set outside the card inlet. The flat-push card-loading motor 71 drives the card-pushing plate 73 to move horizontally to push the cards and the card-supporting plate 74 to lift and lower to load the cards. The card-supporting plates 74 are respectively inclined relative to the side of the tabletop, and the four sides adopt independent flat-push card loading. By hollowing out part or all of the inner wall of the shuffling tray near the card-feeding device's upper card holder, the edge of the shuffling tray can be expanded to directly below the card-receiving plate, allowing the card-feeding motor of the card-feeding device to also extend directly below the card-receiving plate. This way, most of the card-supporting plate and a small portion of the card-receiving plate are located above the shuffling frame. This not only effectively increases the shuffling space while increasing the size of the shuffling tray but also shortens the card-feeding channel length of the card-feeding device. This allows for a more rational placement of the card-receiving block of the pushing device and the card-feeding device's inlet, reducing interference and limitations on the shuffling tray and shuffling space from the pushing and feeding devices, thus maximizing the size of the shuffling frame and the shuffling tray. On the same size mahjong machine base plate, without increasing the overall thickness of the mahjong machine, the shuffling tray and shuffling space are increased; for example, shuffling 108 tiles (62 mahjong tiles) can be achieved on a 36-table mahjong machine. However, in the above-mentioned mahjong machine structure, when dismantling and repairing the card feeding device, it is necessary to first dismantle the flat-push card feeding device. When installing the card feeding device, professional personnel are required to install, adjust and debug the flat-push card feeding device. The dismantling and assembly work is large and the maintenance cost is high. Summary of the Invention

By arranging the flat pushing card device in a tilted manner, the corresponding card feeding port and the supporting plate are also arranged along the side edge of the tabletop in a tilted manner, and the mahjong tile wall is in a tilted state when being lifted to the tabletop, which meets 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 the mahjong tile wall is pushed to the supporting plate in a flat pushing manner, and then is lifted to the tabletop, so that the problem of card reversal does not exist.

[0065] As shown in Figure 2 and Figure 8 In the utility model, the card receiving block 62 of the card pushing device 6 is arranged outside the card feeding port of the card feeding channel, one end of the card receiving plate 72 extending along the length direction is the card feeding port of the card storage channel, the other end of the card receiving plate 72 extending along the length direction is provided with a side baffle 721, the front and rear blocks 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 or integrally formed with the supporting plate 74.

[0066] In the utility model, the height of the card outlet of the card feeding channel is lower than the lowest position of the card supporting plate, and the thickness of one mahjong card is exceeded. In the preferred embodiment, the card supporting block 62 of the card pushing device has at least three height positions: the first card supporting position, the second card supporting position and the card pushing position. When the mahjong cards are stacked and pushed: the card supporting block 62 first supports the first mahjong card sent by the card feeding device at the first card supporting position; the card supporting block 62 is lowered to the second card supporting position to support the second mahjong card sent by the card feeding device, and the second mahjong card is stacked on the first mahjong card; then, the card supporting block 62 is raised to the card pushing position, and the pushing head 63 pushes the two mahjong cards stacked above and below out of the card supporting block 62; the card supporting block 62 is lowered to reset to the first card supporting position; the pushing head 63 is also reset and waits for the next time of stacking and pushing. The card pushing position of the card supporting block 62 is at least two mahjong card thicknesses higher than the second card supporting position.

[0067] In the utility model, the card supporting block 62 of the card pushing device 6 is arranged outside the shuffling frame, therefore, the card outlet of the card feeding device 5 and the card inlet of the flat pushing card feeding device 7 are also arranged outside the shuffling frame. In this way, the shuffling space is not occupied when the card supporting block is lowered, so that the shuffling frame and the shuffling large disc can be maximized.

[0068] In an embodiment of the utility model, the card supporting plate can adopt the prior art disclosed in the patent document with the publication number CN117982871A and the like:

[0069] The card feeding seat 70 of the flat pushing card feeding device 7 is hollowed out close to the inner side wall part of the shuffling large disc or is completely hollowed out, so that the edge of the shuffling large disc 2 can be expanded to be directly below the card supporting plate 72, and the card feeding motor 51 of the card feeding device 5 can also be extended to be directly below the card supporting plate 72. In this way, most of the card supporting plate 74 and part of the card supporting plate 72 are located above the shuffling frame, and the card feeding outlet of the card feeding device 5 and the card supporting block 62 of the card pushing device 6 are located directly below the card supporting 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 positions of the card supporting block 62 of the card pushing device 6 and the card inlet of the flat pushing card feeding device 7 are more reasonable; the interference and limitation of the flat pushing card feeding 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 in the same size of the mahjong machine bottom plate, for example, 108 mahjong cards of 62 mahjong cards are realized on a 36 table mahjong machine. However, from the perspective of the shuffling process, the card feeding channel of the card feeding device 5 is located above the shuffling frame, and the card supporting block 62 of the card pushing device 6 is located below the shuffling frame, so that the card feeding channel of the card feeding device 5 and the card supporting block 62 of the card pushing device 6 are not in the same plane, and the shuffling process is not smooth. Figure 1It can be seen that the inner side card guiding shaft 706 of the card receiving plate 74 is still located on the outer side of the card shuffling tray 2. In the prior art, the inner and outer card guiding shafts of the card receiving plate are fixed on the bottom of the card receiving plate. When the card receiving plate is lowered, the lower end of the inner side card guiding shaft approaches or even penetrates through the bottom plate, thereby limiting the expansion of the card shuffling tray and affecting the further increase of the card shuffling space.

[0070] Therefore, in the preferred embodiment of the utility model, as shown in the figure, Figure 2 the inner side card guiding shaft 706 of the card receiving plate 74 is arranged above the inner side of the outer circumference of the card shuffling tray 2. The inner side card guiding shaft 706 is fixedly connected or integrally formed on the card receiving seat 70, the whole card shuffling barrel 4 or the card feeding seat 53. An inner side card guiding sleeve 740 is sleeved on the inner side card guiding shaft 706, and the inner side card guiding sleeve 740 is fixedly connected with the card receiving plate 74. In this way, the length of the inner side card guiding 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 card shuffling space to affect card shuffling. Therefore, the card receiving plate can be further pushed inward and does not interfere with the card shuffling space, so that the card receiving plate is not limited by the card shuffling frame (card shuffling barrel) in terms of the side distance, thereby realizing that a larger card shuffling tray can be selected for the same card receiving plate side distance, a larger card shuffling tray can be used to shuffle more cards and more tiles, and the needs of more players can be met. For example, 120 pieces of 64 mahjong can be realized on a 36-table mahjong machine, and the minimum side distance of the card receiving plate can be 290 mm.

[0071] In the preferred embodiment, the inner side end of the card receiving seat 70 is provided with an extension arm 705, and the inner side card guiding shaft 706 of the card receiving plate 74 is fixedly arranged on the extension arm 705. The card receiving seat 70 is provided with a card guiding shaft seat 704 on the outer side section, and the outer side card guiding shaft 741 of the card receiving plate 74 is slidingly installed in the card guiding shaft seat 704. In this way, the bearing structure of the card receiving plate is more balanced, and the lifting guiding and positioning reference of the inner and outer sides of the card receiving plate are all on the card receiving seat, so that installation and debugging are more convenient, and the lifting action is more stable and reliable.

[0072] In the preferred embodiment, the inner side card guiding shaft 706 of one card receiving plate 74 is arranged between the inner side end and the length side of another card receiving plate 74. In this way, the gap between the two card receiving plates can be fully utilized, which not only facilitates the arrangement of the extension arm and the flat pushing and tile blocking structure, and is structurally reasonable, stable and reliable, but also facilitates the formation of good support on the narrow side between the two card receiving seats on the table panel.

[0073] In other embodiments, the inner side card guiding shaft 706 of the card receiving plate 74 can also be arranged on the front side of the length side, i.e. between the card receiving plate 74 and the central lifting device of the mahjong machine (between the card receiving plate and the tile feeding hole of the card shuffling barrel). Such a structure is particularly suitable for the case where the inner side card guiding shaft of the card receiving plate is fixedly arranged on the card shuffling barrel, and the overall structure is more simple and reasonable.

[0074] In an embodiment of the present application, the upper card seat can be configured using the prior art disclosed in patent documents with publication number CN117982871A and the like.

[0075] The upper card seat no longer has a front side wall on the front side near the shuffling frame, so that the internal space of the upper card seat (the space below the card receiving plate) becomes an open space, allowing the shuffling tray / shuffling frame and the card feeding motor to 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 card receiving plate that does not rise and fall. Since the top wall is fixed, it is relatively thin, and the shuffling frame is arranged below it, which does not continue to increase the height difference between the card outlet position of the card feeding device and the lowest position of the card receiving plate, nor does it increase the overall thickness of the mahjong machine. It is more reasonable than the bottom hollow structure disclosed in patent documents with publication number CN109794059A and the like. 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 convexly arranged towards the rear, thereby forming a plurality of grooves in front of it for accommodating part of the components of the card feeding transmission mechanism. The left and right side walls of the upper card seat are used to fixedly connect the card guiding shaft seat. In order to increase the overall strength of the upper card seat and facilitate injection molding, a bottom wall is also provided, but the bottom wall can be hollowed out at the interference position with the shuffling tray and the card feeding motor to avoid affecting the arrangement of the two. However, in this structure, the top wall of the upper card seat is a thin-walled structure with a relatively long length, which results in poor structural strength and load-bearing capacity, and the guide shaft seat inside the upper card seat and its connected side wall structure also limit the arrangement and maintenance and disassembly of the washing space and the card feeding device.

[0076] Therefore, in the preferred embodiment of the present application, 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] Therefore, in the preferred embodiment of the utility model, as shown in Figures 9 to 15 The card supporting plate transmission mechanism comprises:

[0085] 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 71;

[0090] In this way, the gear transmission mechanism is adopted, the cam is installed on the upper card arm shaft and is driven in cooperation with the crank gear, the torque transmission 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 torque transmission, and is also more convenient to install and maintain.

[0092] The embodiment preferably, 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.

[0093] The embodiment preferably, the crank 747 is driven in cooperation with the cam groove 7461 on the upper card arm 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 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.

[0094] The embodiment preferably, 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 occupation and influence of the upper card arm cam and the gear transmission mechanism on the shuffling space be reduced, but also the transmission structure is more stable and reliable.

[0095] The embodiment preferably, 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.

[0096] The embodiment preferably, the bottom of one of the upper card arm shaft seats 7451 on the upper card seat 70 close to 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] The action process of the flat pushing mahjong device is preferably as follows:

[0102] 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.

[0103] 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, and the tile blocking frame is used to prevent the mahjong tile wall on the supporting plate from moving inwardly.

[0104] 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.

[0105] 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 that can move relative to the tile pushing head, and positioning and fixing it by the tile plate during flat push tile to ensure that it is flush with the blocking frame and its outer blocking part, the defect of easy looseness during flat push blocking by the tile pushing head is overcome. 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 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.

[0106] 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.

[0107] In this embodiment, a flat push signboard structure is preferably provided, as shown in Figure 20 As shown, the four signboard frames are integrally connected to form a square signboard cover 8, and 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, and an opening is provided between the inner signboard plate 54 and the outer signboard plate 9 for the pusher head 63 to pass through, and a movable flap 92 is provided in the opening, which is installed on the mahjong machine tabletop in a manner that can be flipped up and down and is reset by a resilient member; wherein the outer signboard plate 9 is a separate component which is directly fixed on the mahjong machine bottom plate, and 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.

[0108] 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 As shown, the inner signboard plate 54 is integrally formed with the inner housing 532 of the tile feeding seat 53.

[0109] In this embodiment, as shown in Figure 5 and Figure 20 As shown, a tile blocking 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, and when the tile receiving block 62 receives the mahjong tiles fed by the tile feeding device 5, the tile blocking block 64 and the tile outlet of the tile feeding device are respectively located on the 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(suspension arm part 707) are respectively located on the other opposite sides of the tile receiving block 62. In this way, not only can the mahjong tiles be prevented from falling into the space outside the tile receiving block and causing failure, but also the structure is more reasonable and reliable.

[0110] 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.

[0111] 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 tiles 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 tiles 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.

[0112] Preferably, in the embodiment, a card pushing and guiding structure is arranged, such as 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 tiles, 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 tiles, 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 tiles 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 tiles can be adjusted by the horn during the pushing process of the card pushing head, so that the angle and direction of the mahjong tiles entering the tile storage channel of the flat pushing and carrying device are consistent with the length direction of the card supporting plate and are arranged in order.

[0113] 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°.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] Preferably, 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 and dehumidify and deodorize the shuffling space.

[0121] Preferably, 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.

[0122] In this preferred embodiment, the plate support step 43 is provided with a plate-raising rocker arm clearance groove 431 for accommodating the plate-raising rocker arm 743 and the plate-raising curved cam 744 in the flat-push plate-raising device. Thus, when the plate support 74 descends, the plate-raising rocker arm clearance groove 431 can accommodate the plate-raising rocker arm 743 and the plate-raising curved cam 744, allowing the plate support step 43 to provide good support for the plate support 74, and is easy to form and occupies little space.

[0123] In this preferred embodiment, one end of the plate step 43 is provided with a clearance groove 432 or clearance hole for accommodating the extension arm 705 in the flat-push plate-feeding device. In this way, the extension arm 705 on the plate-feeding seat 70 can be inserted into the clearance groove 432 or clearance hole, which not only avoids mutual interference, but also forms a positioning fit and reliable support.

[0124] In other embodiments, the inner card-laying guide shaft 706 of the card-laying plate 74 can also be fixed to the card-laying plate step 43 of the shuffling tank. In this way, the extension arm 705 does not need to be provided on the card-laying seat 70, which simplifies the structure and makes it easier to form.

[0125] In this preferred embodiment, the plate support step 44 is provided with a plate-raising rocker arm support 441 for supporting the plate-raising rocker arm shaft 745 in the flat-push plate-raising device, and a cantilever support 442 for supporting the cantilever part 707 in the flat-push plate-raising device. In this way, the shuffling drum can provide reliable support for the plate-raising rocker arm shaft 745 and the cantilever part 707 on the plate-raising seat 70, thereby increasing the support strength and weight that the plate support plate and the plate holder can bear.

[0126] In this preferred embodiment, the mounting ring 46 is provided with a pusher seat support 461 for supporting the pusher seat 65 in the pusher device 6 and an upper seat support 462 for supporting the upper seat 70 in the flat-push card-loading device 7. Thus, the pusher seat 65 in the pusher device 6 is supported by the pusher seat support 461 and fixed to the shuffling tank and the base plate by fasteners, and the upper seat 70 in the flat-push card-loading device 7 is fixed to the shuffling tank and the base plate by the upper seat support 462 and fasteners. The inner and outer sides of the pusher seat 65 and the upper seat 70 are leveled by supports, facilitating positioning, installation, and adjustment.

[0127] In this preferred embodiment, such as Figure 3 and Figure 18 As shown, the card feeding mounting port 47 extends downwards from the card support plate step 43 to the mounting ring 46. The inner end of the card feeding seat 53 is fixedly installed at the card support plate step 43, and the outer side of the card feeding seat 53 rests on the mounting ring 46 and the guide plate step 45 and is fixed by fasteners. The card suction wheel 52 is located above the card feeding mounting port 47, and the card feeding motor 51 is located outside the card support plate step 43. In this way, the mounting screws of the card feeding device 5 are all vertical, making disassembly and assembly very convenient.

[0128] In this preferred embodiment, such as Figure 22and Figure 23 As shown in the figure, the card feeding seat 53 includes an outer shell 531 and an inner shell 532 fixedly connected as a whole, a card feeding passage is arranged between the two, the outer shell 531 extends beyond the card feeding passage to form a card feeding side stop portion 5311; the outer shell 531 is placed on the mounting ring 46 and fixedly connected, and the inner shell 532 is placed on the card guiding step 45 and fixedly connected with the whole shuffling barrel.

[0129] The mahjong tile arrangement method of the mahjong machine adopts the following steps:

[0130] 1) Card feeding; the card feeding device 5 picks up mahjong tiles from the shuffling tray 2 and feeds them to the tile pushing device 6;

[0131] 2) Tile stacking and pushing; the tile receiving block 62 of the tile pushing device 6 receives a mahjong tile fed by the card feeding 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 fed by the card feeding device 5; the tile receiving block 62 ascends to the tile pushing position and the tile pushing head 63 pushes the two mahjong tiles stacked into a stack to the tile receiving plate 72 of the flat tile pushing device 7, and then the tile receiving block 62 and the tile pushing head 63 are reset respectively;

[0132] 3) Repeat the above step 2) until the tile receiving plate 72 of the flat tile pushing device 7 stores the required multiple stacks of mahjong tiles;

[0133] 4) Flat tile pushing; after receiving the tile feeding instruction, the tile receiving plate 74 of the flat tile pushing device 7 descends to the bottom from the tabletop; the tile pushing plate 73 pushes the multiple stacks of mahjong tiles on the tile receiving plate 72 to the tile receiving plate 74; the tile receiving plate 74 ascends to the tabletop.

[0134] As Figure 1 shown, the existing windmill-shaped mahjong machine (36 tabletop 81.5*81.5cm square) has a shuffling tray and an effective shuffling space with a maximum diameter of 600mm, and can only shuffle 108 62 mahjong tiles. As Figure 2 shown, the same size mahjong machine core adopts the structure of the embodiment, the shuffling tray and the effective shuffling space can have a maximum diameter of 650mm, and 120 64 mahjong tiles can be shuffled on the 36 tabletop mahjong machine, and the minimum distance between the tile receiving plates can be 290mm.
