Description

Technical Field

[0001] This utility model belongs to the technical field of mahjong machines, and in particular relates to a mahjong machine and its flat-push tile-loading device. Background Technology

[0002] Mahjong is widely enjoyed as a recreational activity and is also considered a competitive sport. Traditional mahjong machines place the tiles parallel to the edges of the table after they are raised, and the tiles are very close to the edge, resulting in an unreasonable arrangement. Before drawing a tile, players need to manually move the tiles forward and diagonally to a suitable position. During this process, the tiles are prone to tipping over, causing inconvenience to the players.

[0003] Patent documents with publication numbers CN117982870A, CN117982871A, and CN117982868A disclose a mahjong machine. The card-carrying plate transmission mechanism in its flat-push card-laying device includes: card-laying curved cams, two of which are respectively installed on the left and right sides of the bottom of the card-laying plate. The left and right ends of the bottom of the card-laying plate are slidably connected to the card-laying seat via two guide shafts or sliding sleeves; card-laying rocker arms, two of which cooperate with the two card-laying curved cams; card-laying rocker arm shafts, which are rotatably mounted on the card-laying seat, and the two card-laying rocker arms are respectively fixed on the two card-laying rocker arm shafts; a card-laying drive cam, which is installed on the card-laying seat and driven to rotate by a flat-push card-laying motor; and a card-laying connecting rod, which is driven to move by the card-laying drive cams. The card-laying connecting rod drives the two card-laying rocker arm shafts to rotate synchronously, thereby driving the card-laying plate to rise and fall by rotating the two card-laying rocker arms. In this design, the card-adding cam is relatively small, the card-adding rocker arm is mounted high and oscillates intermittently, and the rocker arm extends forward and is suspended in the air. This allows the card-adding linkage and the card-adding drive cam to be positioned further back, resulting in the card-supporting plate transmission mechanism encroaching less on the shuffling space. This allows for a larger diameter of the shuffling disc and increased shuffling space, improving shuffling efficiency and reducing the likelihood of mahjong tiles colliding with each other on the shuffling disc, thus reducing shuffling noise. However, the linkage movement is prone to obstruction, the two card-adding rocker arms are prone to uneven force distribution, resulting in poor stability and synchronization, and making installation, maintenance, and debugging more difficult. Furthermore, the suspended card-adding rocker arm shaft and cam linkage drive mechanism result in insufficient support strength and weak load-bearing capacity of the card-supporting plate.

[0004] Patent documents with publication numbers CN119656572A, CN119680179A, CN119701316A, and CN119524380A disclose a mahjong machine. The card-carrying plate transmission mechanism in its flat-push card-loading device includes: a card-loading base and a card-carrying plate for simultaneously loading multiple mahjong tiles onto the table; two card-loading curved cams, respectively mounted on the left and right sides of the bottom of the card-carrying plate; two card-loading rocker arms, each cooperating with one of the two card-loading curved cams; two card-loading rocker arm shafts, rotatably mounted on the card-loading base, with the card-loading rocker arms fixedly mounted on the shafts; two card-loading rocker arm cams, fixedly connected to the card-loading rocker arm shafts, each with a cam groove; and two first gears, rotatably mounted on the card-loading base, which are driven by cranks in cooperation with the card-loading rocker arm cams; the two first gears are driven synchronously by a flat-push card-loading motor. However, in this structure, during the transmission process between the first gear and the card-mounting rocker arm cam via the crank, the rollers (or rollers) on the crank move back and forth between the two ends of the card-mounting rocker arm cam. The rotation axis of the card-mounting rocker arm cam (the card-mounting rocker arm shaft) is located at one end, while the first gear rotates at a constant speed. This results in the card-mounting rocker arm cam oscillating at a non-uniform speed, and the lifting and lowering process of the card-mounting plate is also non-uniform. Some sections of the cam curve are too fast, causing unstable and unreliable lifting and lowering motion. Furthermore, the transmission fit between the rollers (or rollers) on the crank and the cam groove on the card-mounting rocker arm cam is a loose fit (single-sided limiting fit), which cannot achieve a double-sided limiting fit across the entire cam curve. This limits the transmission torque and also causes unstable operation. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides a mahjong machine and its flat-push card-feeding device. The card-feeding plate transmission mechanism adopts a full gear transmission, which enhances the torque transmission capacity and load-bearing capacity, improves the stability and reliability of the card-feeding plate lifting movement, and makes the transmission structure more reasonable and maintenance and installation more convenient.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mahjong machine's flat-push tile-loading device includes a tile-loading base, a tile-receiving plate for receiving and arranging multiple stacks of mahjong tiles, a tile-supporting plate for simultaneously loading multiple stacks of mahjong tiles onto the table, and a tile-pushing plate for flat-pushing the multiple stacks of mahjong tiles from the tile-receiving plate onto the tile-supporting plate. The tile-receiving plate forms a tile-storage channel for storing the multiple stacks of mahjong tiles. The tile-supporting plate is located inside the tile-receiving plate and can move up and down, while the tile-pushing plate is located outside the tile-receiving plate and pushes tiles from the outside in. The device also includes a tile-supporting plate transmission mechanism for driving the tile-supporting plate to move up and down. The tile-supporting plate transmission mechanism includes: two tile-loading curved cams, respectively installed on the left and right sides of the bottom of the tile-supporting plate, each with a tile-loading curved cam groove; two tile-loading rocker arms, each cooperating with one of the two tile-loading curved cams; and two... The system includes a card-mounting rocker arm shaft, which is rotatably mounted on the card-mounting base. The card-mounting rocker arm is fixedly connected to or integrally formed with the card-mounting rocker arm shaft. It also includes two card-mounting rotating gears, each rotatably mounted on the card-mounting base and fixedly connected to or integrally formed with the card-mounting rocker arm shaft. Finally, it comprises two first gears, each rotatably mounted on the card-mounting base. The first gears are incomplete gears, having both toothed and toothless portions. They engage with the card-mounting rotating gears for transmission: when the toothed portion of the first gear engages with the card-mounting rotating gear, the first gear drives the card-mounting rotating gear to rotate; when the toothless portion of the first gear engages with the card-mounting rotating gear, the card-mounting rotating gear does not rotate. The two first gears are driven synchronously by a flat-push card-mounting motor.

[0008] Preferably, the first gear is driven to reciprocate by a flat-push motor, and the maximum rotation range of the first gear is 120° to 280°.

[0009] Preferably, the card-loading rocker arm shaft is provided with a card-loading rocker arm, a card-loading rocker arm seat, and a card-loading rotating gear in sequence from front to back, and the card-loading rocker arm shaft and the card-loading rocker arm seat can rotate relative to each other.

[0010] Preferably, the gear for mounting the license plate is a sector gear.

[0011] Preferably, it also includes two second gears that mesh with each other and rotate synchronously. The first gear is a double gear, with the front gear of the double gear having a toothed part and a toothless part. The rear gear of the double gear meshes with the second gear for transmission, and one of the second gears is driven to rotate by a flat-push motor.

[0012] Preferably, the device also includes a card-pushing transmission mechanism for driving the card-pushing plate to move horizontally. The card-pushing transmission mechanism includes a horizontal pushing cam and a horizontal pushing swing rod. The upper end of the horizontal pushing swing rod is movably connected to the card-pushing plate, and the lower end of the horizontal pushing swing rod is hinged to the upper card holder. The card-pushing motor drives the horizontal pushing swing rod to swing back and forth through the horizontal pushing cam, thereby driving the card-pushing plate to move back and forth to push the card.

[0013] Preferably, the push cam is coaxially fixed and rotates synchronously with the first gear or the second gear; the cam curve of the push cam includes a non-driving segment and a driving segment: when the push cam is in the non-driving segment, it does not drive the push plate to move. At this time, the toothed part on the first gear meshes with the plate-raising rotating gear, and the first gear drives the plate-raising rotating gear to rotate, thereby driving the plate to move up and down; when the push cam is in the driving segment, it drives the push plate to push the plate or reset. At this time, the toothless part on the first gear engages with the plate-raising rotating gear, and the plate-raising rotating gear does not rotate.

[0014] Preferably, the card-pushing plate transmission mechanism also includes a card-pushing frame and a flat-push slider. The flat-push slider slides back and forth on the card-pushing frame, and the card-pushing plate is fixed on the flat-push slider. The upper end of the flat-push rocker arm is movably connected to the flat-push slider, and the lower end of the flat-push rocker arm is hinged to the upper card holder through the flat-push rocker arm shaft. A flat-push rocker arm is fixed on the flat-push rocker arm shaft. The swing end of the flat-push rocker arm is movably engaged with the flat-push cam through a roller. The flat-push card-pushing motor drives the flat-push rocker arm to swing back and forth through the flat-push cam, thereby driving the flat-push slider and the card-pushing plate to slide back and forth to push the card.

[0015] Preferably, the upper end of the horizontal push swing arm is hinged to the card pusher plate, and the lower end of the horizontal push swing arm is hinged to the card holder through the horizontal push swing arm shaft. A horizontal push rocker arm is fixed on the horizontal push swing arm shaft. The swing end of the horizontal push rocker arm is in movable cooperation with the horizontal push cam through a roller. The horizontal push card-adding motor drives the horizontal push swing arm and the card pusher plate to swing back and forth through the horizontal push cam to push the card.

[0016] A mahjong machine includes a flat-push tile-loading device as described above.

[0017] Because this utility model adopts the above technical solutions, it uses a full gear transmission plate transmission mechanism, which has a more reasonable transmission structure, smoother motion coordination, greater transmission torque, better load-bearing capacity of the plate, better stability and reliability of the plate lifting motion, more convenient installation and debugging, easier maintenance and disassembly, and lower manufacturing cost.

[0056] Example 1:

[0057] like Figure 1 and Figure 2 The illustrated mahjong machine's flat-push tile-loading device includes a tile-receiving plate 72 for receiving and arranging multiple stacks of mahjong tiles, a tile-supporting plate 74 for simultaneously loading multiple stacks of mahjong tiles onto the table, and a tile-pushing plate 73 for flat-pushing the multiple stacks of mahjong tiles from the tile-receiving plate 72 onto the tile-supporting plate 74. The tile-receiving plate 72 has a storage channel for storing the multiple stacks of mahjong tiles. The tile-supporting plate 74 is located inside the tile-receiving plate 72 and can move up and down. The tile-pushing plate 73 is located outside the tile-receiving plate 72 and pushes tiles from the outside in. It also includes a tile-loading base 70 and a flat-push tile-loading motor 71. The tile-receiving plate 72 is fixedly mounted on the tile-loading base 70, which has a tile-loading transmission mechanism. The flat-push tile-loading motor 71 drives the tile-pushing plate 73 to move horizontally and the tile-supporting plate 74 to move up and down to load tiles via the tile-loading transmission mechanism. The tile-loading transmission mechanism includes a tile-supporting plate transmission mechanism for driving the tile-supporting plate 74 to move up and down and a tile-pushing plate transmission mechanism for driving the tile-pushing plate 73 to move horizontally. In other embodiments, the plate holder 72 may also be mounted on the plate holder 70 in a way that allows it to be raised and lowered and is driven to rise and fall by the plate-raising motor 71.

[0058] In this embodiment, one end of the card-bearing plate 72 extending along the length direction is the card inlet of the card storage channel. A card-bearing block of the card-pushing device is provided outside the card inlet. The other end of the card-bearing plate 72 extending along the length direction is provided with a side baffle. The front and rear obstructions of the card storage channel are a front baffle 742 and a card-pushing plate 73, respectively. The front baffle 742 is fixedly connected to the card-supporting plate 74 or integrally formed.

[0059] In this embodiment, as Figure 1 As shown, the plate-carrying transmission mechanism includes:

[0060] Two plate-mounting curved cams 744 are respectively installed on the left and right sides of the bottom of the plate support plate 74, and the two plate-mounting curved cams 744 are provided with plate-mounting curved cam grooves 7441;

[0061] Two license plate mounting rocker arms 743 are respectively coordinated with two license plate mounting curved cams 744 for movement;

[0062] Two license plate mounting arm shafts 745 are rotatably mounted on the license plate mounting base 70;

[0063] Two rotating gears 746 are mounted on the plate holder 70 in a rotatable manner. The rotating gears 746 are fixedly connected to or integrally formed with the plate rocker arm shaft 745.

[0064] Two first gears 747 are rotatably mounted on the license plate holder 70. The first gears 747 are incomplete gears, with toothed portions 7471 and toothless portions 7472. The first gears 747 engage with the license plate rotating gear 746 for transmission: when the toothed portion 7471 of the first gear 747 meshes with the license plate rotating gear 746, the first gear 747 drives the license plate rotating gear 746 to rotate; when the toothless portion 7472 of the first gear 747 engages with the license plate rotating gear 746, the license plate rotating gear 746 does not rotate. The two first gears 747 are driven to rotate synchronously by a flat-push license plate motor 71.

[0065] In this way, the use of a full gear transmission mechanism results in a reasonable structure, smooth movement, large transmission torque, better stability and reliability of the lifting and lowering motion of the sign holder, easier installation and debugging, easier maintenance and disassembly, and lower manufacturing costs.

[0066] In this preferred embodiment, during the lifting and lowering of the plate holder 74, the two plate-loading rocker arms 743 rotate synchronously in opposite directions, and the two first gears 747 rotate synchronously in opposite directions. This results in a reasonable lifting and lowering structure for the plate holder and smooth movement.

[0067] In this preferred embodiment, the first gear 747 is driven to reciprocate by the flat-push card-adding motor 71, and the maximum rotation range of the first gear 747 is 120° to 280°. In this way, the first gear drives the card-adding rotating gear and the card-adding rocker arm to reciprocate (forward and reverse), which can further reduce the encroachment and impact of the card-adding rocker arm and the card-adding rotating gear on the shuffling space.

[0068] In this preferred embodiment, the card-adding rocker arm 743, the card-adding rocker arm seat, and the card-adding rotating gear 746 are sequentially mounted on the card-adding rocker arm shaft 745 from front to back. The card-adding rocker arm shaft 745 and the card-adding rocker arm seat can rotate relative to each other. This not only reduces the encroachment and impact of the card-adding rotating gear on the shuffling space, but also makes the transmission structure more stable and reliable.

[0069] In this preferred embodiment, the bottom of the card-loading rocker arm shaft seat is supported by a card-shuffling barrel or a card-feeding device, or by an independent support column, which is fixedly connected to or integrally formed with the card-loading seat. This maximizes the support strength and load-bearing capacity of the card-supporting plate.

[0070] In this preferred embodiment, the front end of the card-loading rocker arm shaft 745 is fixedly connected to or integrally formed with the card-loading rocker arm 743, and the rear end of the card-loading rocker arm shaft 745 is fixedly connected to or integrally formed with the card-loading rotating gear 746. The card-loading rocker arm shaft 745 is mounted on the card-loading seat 70 via bearings. This can minimize the encroachment of the card-loading rocker arm and the card-loading rotating gear on the shuffling space.

[0071] In this preferred embodiment, the two license plate rotating gears 746 are sector gears to reduce costs and save space. In other embodiments, the two license plate rotating gears 746 may also be integral gears.

[0072] In this preferred embodiment, two second gears 748 are also included. The two second gears 748 mesh with each other and rotate synchronously. The first gear 747 is a double gear. The front gear of the double gear has a toothed portion 7471 and a toothless portion 7472. The rear gear of the double gear meshes with the second gears 748 for transmission. One of the second gears 748 is driven to rotate by a flat-push mounting motor 71. In this way, the first gear adopts a double gear structure to mesh with the second gear and the mounting rotating gear respectively, resulting in low manufacturing cost, compact structure, small space occupation, stable and reliable transmission, and convenient installation and maintenance. The double gear can be integrally formed, or the front gear and the rear gear can be formed separately and then fixedly connected as one piece.

[0073] In this preferred embodiment, such as Figure 2 As shown, the card-pushing plate transmission mechanism includes a card-pushing frame 731, a flat-push slider 7311, a flat-push cam 732, and a flat-push swing rod 734. The flat-push slider 7311 slides back and forth on the card-pushing frame 731 along the guide rod. The card-pushing plate 73 is fixed on the flat-push slider 7311. The upper end of the flat-push swing rod 734 is movably connected to the flat-push slider 7311, and the lower end of the flat-push swing rod 734 is hinged to the upper card holder 70 through the flat-push swing rod shaft 735. A flat-push rocker arm 733 is fixed on the flat-push rocker arm shaft 735. The swing end of the flat-push rocker arm 733 is movably engaged with the flat-push cam 732 through a roller. One first gear 748 is driven to rotate by the flat-push card-feeding motor 71, and the other first gear 748 is coaxially fixed and rotates synchronously with the flat-push cam 732. Thus, the flat-push card-feeding motor 71 drives the flat-push slider 7311 to slide back and forth through the flat-push cam 732 and the flat-push swing rod 734 to push the card. Further preferably, the horizontal rocker arm 733 is positioned between the horizontal card-adding motor 71 and the horizontal cam 732. Further preferably, a card-pushing cover plate is fixedly mounted above the card-pushing plate 73.

[0074] In another embodiment of the card-pushing plate transmission mechanism, the upper end of the horizontal pusher 734 is hinged to the card-pushing plate 73, and the lower end of the horizontal pusher 734 is hinged to the upper card holder 70 via the horizontal pusher shaft 735. A horizontal pusher rocker arm 733 is fixed on the horizontal pusher shaft 735, and the swing end of the horizontal pusher rocker arm 733 is movably engaged with the horizontal pusher cam 732 via a roller. The horizontal pusher card-feeding motor 71 drives the horizontal pusher 734 and the card-pushing plate 73 to swing back and forth through the horizontal pusher cam 732 to push the cards. In other embodiments, the card-pushing plate transmission mechanism can also refer to the various embodiments disclosed in patent documents such as CN109381855A, CN109794059A, CN112023390A, CN114247127A, CN114146397A, and CN117982871A.

[0075] In this preferred embodiment, the horizontal push cam 732 is coaxially fixed and rotates synchronously with a second gear 748. In other embodiments, the horizontal push cam 732 can also be coaxially fixed and rotate synchronously with a first gear 747, or be independently driven by a horizontal push motor. Figure 3 and Figure 4 As shown, the cam curve of the push cam 732 includes a non-drive segment 7321 and a drive segment 7322: When the push cam 732 is in the non-drive segment 7321, it does not drive the push plate 73 to move. At this time, the toothed part 7471 on the first gear 747 meshes with the plate-raising rotating gear 746, and the first gear 747 drives the plate-raising rotating gear 746 to rotate, thereby driving the plate support 74 to move up and down. When the push cam 732 is in the drive segment 7322, it drives the push plate 73 to push the card or reset. At this time, the toothless part 7472 on the first gear 747 engages with the plate-raising rotating gear 746. The plate-raising rotating gear 746 does not rotate, and the plate support 74 does not move up and down.

[0076] In this preferred embodiment, such as Figure 3 and Figure 4 As shown, the angle range a of the non-driving section 7321 of the push cam 732 is 70° to 130°, and the angle range b of the driving section 7322 is 70° to 130°; Figure 5 and Figure 6 As shown, the angular range of the toothed portion 7471 on the first gear 747 is greater than the angular range a of the non-driving section 7321 on the push cam 732, and the angular range of the toothless portion 7472 is greater than the angular range b of the driving section 7322 on the push cam 732. This results in a reasonable pushing speed and stable and reliable operation.

[0077] In other implementations of the pusher cam, such as Figure 20 As shown, after the drive section 7322 reaches its highest point, a push-card positioning and holding section 7323 is extended. This setting ensures the push-card positioning and the stability and reliability of the push-card, reducing the difficulty of assembly and debugging.

[0078] In this preferred embodiment, the push cam 732 is equipped with a signal source magnet, and the upper card holder 70 is equipped with a control circuit board 737 for detecting the motion state of the push cam. The control circuit board 737 is equipped with two control elements for sensing the signal source magnet. The two control elements correspond to the highest position stop signal of the card holder and the motor reverse start signal, respectively. In other embodiments, the control circuit board 737 can also be fixedly mounted on the cam cover 736, such as... Figure 21 As shown, the control circuit board 737 is fixed behind the cam cover 736, making disassembly and maintenance more convenient. In other embodiments, the signal source magnet can also be set on the upper rotating gear 746, the first gear 747, or the second gear 748.

[0079] The operation process of the flat-push card-applying device in this embodiment is as follows:

[0080] When the mahjong tiles are stored on the tile holder 72, if Figures 7 to 9 As shown, the card-supporting plate 74 is in the raised state. During the horizontal card-loading operation, the horizontal card-loading motor 71 drives the second gear 748 to rotate clockwise by 70° to 130°. The second gear 748 drives the first gear 747 to rotate counterclockwise by 70° to 130°. The toothed part 7471 of the first gear 747 meshes with the card-loading rotating gear 746, thereby driving the card-loading rotating gear 746 to rotate clockwise by 60° to 90°. The card-loading rotating gear 746 drives the card-loading rocker arm 743 to rotate clockwise by 60° to 90°, and the card-supporting plate 74 descends. At the same time, the horizontal cam 732 is driven by the horizontal card-loading motor 71 to rotate clockwise by 70° to 130°. The roller at the swing end of the horizontal rocker arm 733 moves on the non-drive section 7321 of the horizontal cam 732, and the card-loading plate 73 remains stationary.

[0081] The plate 74 moves from the highest point to the lowest point, as... Figures 10 to 12 As shown, at this time, the toothed part 7471 on the first gear 747 has just disengaged from the card-raising rotating gear 746, and the toothless part 7472 begins to engage with the card-raising rotating gear 746, and the card-supporting plate 74 stops moving; the swing end roller of the horizontal push rocker arm 733 moves to the junction position of the non-drive section 7321 and the drive section 7322 of the horizontal push cam 732, and the card-pushing plate 73 is ready to start pushing the card.

[0082] like Figures 13 to 15As shown, the flat-push tile-feeding motor 71 drives the second gear 748 to continue rotating forward 70° to 130°. The second gear 748 continues to drive the first gear 747 to rotate backward 70° to 130°. The toothless part 7472 of the first gear 747 does not drive the tile-feeding rotating gear 746 to rotate. The tile-feeding rotating gear 746 and the tile-feeding rocker arm 743 do not rotate, and the tile-holding plate 74 remains stationary at the lowest point to receive tiles. At the same time, the flat-push cam 732, driven by the flat-push tile-feeding motor 71, continues to rotate forward 70° to 130°. The roller at the swing end of the flat-push rocker arm 733 moves on the drive section 7322 of the flat-push cam 732, moving from the lowest point to the highest point, thereby driving the tile-pushing plate 73 to push the mahjong tiles on the tile-bearing plate 72 onto the tile-holding plate 74.

[0083] Then, the horizontal push cam 732 is driven by the horizontal push card-adding motor 71 to rotate 70° to 130° in reverse. The roller at the swing end of the horizontal push rocker arm 733 moves on the drive section 7322 of the horizontal push cam 732, returning from the highest point to the lowest point along the same path. The card-adding plate 73 resets. Figure 16 and Figure 17 As shown, simultaneously, the flat-push card-attaching motor 71 drives the second gear 748 to rotate in reverse by 70° to 130°, and the second gear 748 drives the first gear 747 to rotate in the forward direction by 70° to 130°. The toothless part 7472 of the first gear 747 does not drive the card-attaching rotating gear 746 to rotate. The card-attaching rotating gear 746 and the card-attaching rocker arm 743 do not rotate, and the card-holding plate 74 remains stationary at the lowest point. As the first gear 747 rotates back to its original position, the toothed part 7471 of the first gear 747 is ready to begin meshing with the card-attaching rotating gear 746.

[0084] The push-pushing motor 71 drives the second gear 748 to continue rotating in reverse by 70° to 130°. The second gear 748 then drives the first gear 747 to rotate clockwise by 70° to 130°. The toothed part 7471 of the first gear 747 meshes with the card-raising rotating gear 746, which in turn drives the card-raising rotating gear 746 to rotate counterclockwise by 60° to 90°. The card-raising rotating gear 746 then drives the card-raising rocker arm 743 to rotate counterclockwise by 60° to 90°, raising the card-supporting plate 74 to its highest point and thus lifting the mahjong tiles onto the table. Figure 18 and Figure 19 As shown, at the same time, the flat push cam 732 is driven by the flat push card-adding motor 71 to continue to rotate 70° to 130° in reverse. The roller at the swing end of the flat push rocker arm 733 moves on the non-drive section 7321 of the flat push cam 732, away from the junction of the non-drive section 7321 and the drive section 7322, while the card-adding plate 73 remains stationary.
