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] Patent document CN119524380A discloses a horizontal pushing tile-loading device for a mahjong machine, comprising 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 pushing the multiple stacks of mahjong tiles from the tile-receiving plate onto the tile-supporting plate. The tile-receiving plate forms a 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 the tiles from the outside in. It also includes a tile-loading base and a horizontal pushing tile-loading motor. The tile-receiving plate is fixedly mounted on the tile-loading base, which is equipped with a tile-loading transmission mechanism. The horizontal pushing tile-loading motor drives the tile-pushing plate to move horizontally and the tile-supporting plate 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 to move up and down and a tile-pushing plate transmission mechanism for driving the tile-pushing plate to move horizontally. During the process of pushing the tiles onto the rack, the lower layer of mahjong tiles rubs against the felt of the tile support plate, resulting in significant frictional resistance. However, due to the smooth surface of the mahjong tiles, the upper layer experiences less frictional resistance when in contact with the lower layer. Consequently, when the rack reaches its designated position, the lower layer stops moving immediately, but the upper layer continues to move forward after the lower layer stops, leading to unevenness between the two layers. Therefore, players still need to manually arrange the tiles after they are placed on the rack, significantly impacting the playing experience. On mahjong machines without a protective cover on the inside of the tile support plate, there is even a risk of tiles falling back into the shuffling tray, causing machine malfunction. Summary of the Invention

[0003] To solve the above problems, this utility model provides a mahjong machine and its flat-push tile-loading device. The tile-loading plate has a reasonable structural design, which ensures that the mahjong tile wall is neat after the flat-push tile loading, without the need for manual arrangement.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A horizontal pushing device for a mahjong machine includes a receiving plate for receiving and arranging multiple stacks of mahjong tiles, a supporting plate for feeding multiple stacks of mahjong tiles onto the table at once, and a pushing plate for pushing the multiple stacks of mahjong tiles from the receiving plate to the supporting plate. The receiving plate forms a storage channel for storing the multiple stacks of mahjong tiles. The supporting plate is located inside the receiving plate and can move up and down. The pushing plate is located outside the receiving plate and pushes the tiles from the outside in. The device also includes a supporting plate transmission mechanism for driving the supporting plate to move up and down, and a pushing plate transmission mechanism for driving the pushing plate to move horizontally. The pushing surface of the pushing plate includes a first pushing surface and a second pushing surface. The first pushing surface contacts the upper layer of mahjong tiles, and the second pushing surface contacts the lower layer of mahjong tiles. The second pushing surface protrudes from the first pushing surface.

[0006] Preferably, the second pusher surface protrudes 0.5 to 5 millimeters beyond the first pusher surface.

[0007] Preferably, the first push card face and the second push card face are smoothly connected.

[0008] Preferably, the top of the push plate is bent to form the top surface, and the bottom of the push plate is bent to form the bottom surface.

[0009] Preferably, the push plate is fixed on the flat push frame, which is driven to move back and forth by the push plate transmission mechanism.

[0010] Preferably, the card-pushing transmission mechanism includes a horizontal push cam, a horizontal push rocker arm, a horizontal push swing rod, and a horizontal push swing rod shaft. The upper end of the horizontal push swing rod is hinged to the horizontal push frame, and the lower end of the horizontal push swing rod is fixedly connected to the horizontal push swing rod shaft. The horizontal push swing rod shaft is rotatably mounted on the upper card holder. A horizontal push rocker arm is fixed on the horizontal push swing rod shaft. The swing end of the horizontal push rocker arm is movably engaged with the horizontal push cam through a roller. The horizontal push cam is driven to rotate by a horizontal push card-feeding motor.

[0011] Preferably, the top surface of the push plate is provided with multiple oblong holes, and the push plate is fixedly connected to the flat push frame by fasteners passing through the oblong holes; the bottom surface of the push plate is provided with a clearance groove at a position corresponding to the flat push swing arm to avoid the range of motion of the flat push swing arm.

[0012] Preferably, the card-pushing plate transmission mechanism includes a card-pushing frame, a horizontal sliding block, a horizontal sliding cam, a horizontal sliding rocker arm, a horizontal sliding arm, and a horizontal sliding arm shaft. The card-pushing plate is fixed on the horizontal sliding block, which slides back and forth on the card-pushing frame. The upper end of the horizontal sliding arm is movably connected to the horizontal sliding block, and the lower end of the horizontal sliding arm is fixedly connected to the horizontal sliding arm shaft. The horizontal sliding arm shaft is rotatably mounted on the upper card holder, and a horizontal sliding rocker arm is fixed on the horizontal sliding arm shaft. The swing end of the horizontal sliding rocker arm is movably engaged with the horizontal sliding cam through a roller, and the horizontal sliding cam is driven to rotate by a horizontal card-pushing motor.

[0013] Preferably, the card-holding plate transmission mechanism includes a card-holding curved cam, a lifting crank, a first gear, and a second gear. The card-holding curved cam is installed at the bottom of the card-holding plate. The lifting crank is fixedly connected to or integrally formed with the first gear. One end of the lifting crank moves in conjunction with the card-holding curved cam through a roller. The two first gears are rotatably mounted on the card-holding seat. The two second gears mesh and rotate and are driven to rotate by a flat-push card-holding motor. The two first gears mesh and transmit power to each other.

[0014] A mahjong machine includes a flat-push tile-loading device as described above.

[0015] This invention, by adopting the above technical solution, improves the inner structure of the pusher plate from a single plane to two pusher surfaces, so that when the pusher plate pushes the tiles, the upper layer of mahjong tiles will lag slightly behind the lower layer. When the pusher plate stops at the support plate, the upper layer of mahjong tiles will move forward slightly due to inertia and then be basically flush with the lower layer. This reasonable structural design can keep the mahjong tiles stable when they are pushed flat, avoiding the problem of the upper layer of mahjong tiles moving forward or even flipping and falling off. This ensures that the mahjong tile wall is neat and uniform when pushed flat, without the need for manual arrangement. Attached Figure Description

[0037] Example 1:

[0038] like Figures 1 to 5The 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 delivering multiple stacks of mahjong tiles onto the table at once, and a tile-pushing plate 73 for pushing the multiple stacks of mahjong tiles from the tile-receiving plate to the tile-supporting plate. The tile-receiving plate 72 has a tile-storing channel for storing and arranging 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 to the inside. The inner side of the tile-pushing plate 73 is a tile-pushing surface, which includes a first tile-pushing surface 7301 and a second tile-pushing surface 7302. The first tile-pushing surface 7301 contacts the upper layer of mahjong tiles, and the second tile-pushing surface 7302 contacts the lower layer of mahjong tiles. The second tile-pushing surface 7302 protrudes from the first tile-pushing surface 7301.

[0039] In this embodiment, the flat-push card-adding device also includes a card-adding seat 70 and a flat-push card-adding motor 71. The card-bearing plate 72 is fixedly mounted on the card-adding seat 70. The card-adding seat 70 is provided with a card-adding transmission mechanism. The flat-push card-adding motor 71 drives the pusher plate 73 to move horizontally and the support plate 74 to lift and lower the card-adding plate through the card-adding transmission mechanism. The card-adding transmission mechanism includes a support plate transmission mechanism for driving the support plate 74 to lift and lower and a pusher plate transmission mechanism for driving the pusher plate 73 to push horizontally.

[0040] 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.

[0041] In this preferred embodiment, the second pushing surface 7302 protrudes from the first pushing surface 7301 by approximately 0.5 to 5 millimeters. This ensures that when the upper and lower layers of mahjong tiles stop pushing onto the support plate, the upper layer of tiles, after a slight forward inertia, is essentially flush with the lower layer.

[0042] In this preferred embodiment, the first pushing surface 7301 and the second pushing surface 7302 are smoothly connected, and the stability of the mahjong tiles is ensured when pushing the tiles through the first pushing surface 7301 and the second pushing surface 7302.

[0043] In this embodiment, the top of the push plate 73 is bent to form a top surface 7304, and the bottom of the push plate 73 is bent to form a bottom surface 7303. More preferably, the top surface 703 of the push plate 73 has three oblong holes, and the push plate 73 is fixedly connected to the flat push frame 703 by fasteners passing through the oblong holes; the bottom surface 7303 of the push plate 73 has an avoidance groove at a position corresponding to the flat push lever 734 to avoid the range of motion of the flat push lever 734. The width of the avoidance groove is wider than the width of the flat push lever to accommodate mahjong tiles of different sizes, ensuring the pushing effect and the universality of the mahjong machine.

[0044] In this preferred embodiment, the push plate 73 is fixed on the flat push frame 703, and the flat push frame 703 is driven to move back and forth by the push plate transmission mechanism.

[0045] In this preferred embodiment, the card-pushing plate transmission mechanism includes a horizontal push cam 732, a horizontal push rocker arm 733, a horizontal push swing rod 734, and a horizontal push swing rod shaft 735. The upper end of the horizontal push swing rod 734 is hinged to the horizontal push frame 703, and the lower end of the horizontal push swing rod 734 is fixedly connected to the horizontal push swing rod shaft 735. The horizontal push swing rod shaft 735 is rotatably mounted on the upper card holder 70. The horizontal push rocker arm 733 is fixed on the horizontal push swing rod shaft 735. The swinging end of the horizontal push rocker arm 733 is movably engaged with the horizontal push cam 732 through a roller. The horizontal push cam 732 is driven to rotate by the horizontal push card-feeding motor 71. In this way, the horizontal push card-feeding motor 71 drives the card-pushing plate 73 to slide back and forth to push the cards through the horizontal push cam 732 and the horizontal push swing rod 734.

[0046] In this embodiment, the card holder 70 is provided with two card-mounting guide shaft seats 701, and the bottom of the card support plate 74 is equipped with two card-mounting guide shafts 702. The card support plate 74 achieves vertical lifting and guiding through the card-mounting guide shaft seats 701 and the card-mounting guide shafts 702. In other embodiments, one or more card-mounting guide shafts 702 can be installed on the card holder 70, and correspondingly, the guide sleeves slidably sleeved on the card-mounting guide shafts 702 are fixed on the card support plate 74.

[0047] In this preferred embodiment, the card-holding plate transmission mechanism includes a card-attaching curved cam 741, a lifting crank 742, a first gear 743, and a second gear 744. The card-attaching curved cam 741 is mounted on the bottom of the card-holding plate 71. The lifting crank 742 is fixedly connected to or integrally formed with the first gear 743. One end of the lifting crank 742 moves in conjunction with the card-attaching curved cam 741 via a roller. The two first gears 743 are rotatably mounted on the card-attaching seat 70. The two second gears 744 mesh and rotate, driven by a flat-push card-attaching motor 71. The two first gears 743 mesh with the two first gears 744 respectively. In this way, the flat-push card-attaching motor 71 drives the card-holding plate 74 to move up and down to attach the card via the first gears 743, the second gears 744, and the lifting crank 742.

[0048] In this preferred embodiment, the horizontal push cam 732 and the second gear 744 are coaxially fixed, so that the two are driven to rotate synchronously by the horizontal push motor 71.

[0049] In other embodiments of this utility model, the card-pushing plate transmission mechanism includes a card-pushing frame, a flat-push slider, a flat-push cam 732, a flat-push rocker arm 733, a flat-push swing rod 734, and a flat-push swing rod shaft 735. The card-pushing plate 73 is fixed on the flat-push slider, which slides back and forth on the card-pushing frame. The upper end of the flat-push swing rod 734 is movably connected to the flat-push slider, and the lower end of the flat-push swing rod 734 is fixedly connected to the flat-push swing rod shaft 735. The flat-push swing rod shaft 735 is rotatably mounted on the upper card holder 70. The flat-push rocker arm 733 is fixed on the flat-push swing rod shaft 735. The swing end of the flat-push rocker arm 733 is movably engaged with the flat-push cam 732 through a roller. The flat-push cam 732 is driven to rotate by the flat-push card-feeding motor 71.

[0050] The operation process of the flat-push card-adding device in this embodiment is as follows:

[0051] The flat-push motor 71 drives the second gear 744 to rotate, and the flat-push cam 732, which is coaxially fixed with the second gear 744, rotates synchronously. A roller is installed on the flat-push rocker arm 733. The roller contacts the rotating flat-push cam 732. When the roller rolls on the cam surface of the flat-push cam 732, it causes the flat-push rocker arm 733 to swing. The flat-push rocker arm 733 is fixed on the flat-push swing rod shaft 735. The swing of the flat-push rocker arm 733 is transmitted to the flat-push swing rod shaft 735, causing the flat-push swing rod shaft 735 to rotate. The flat-push swing rod 734 is fixed on the flat-push swing rod shaft 735. When the flat-push swing rod shaft 735 rotates, it converts the rotational motion into the forward and backward linear movement of the flat-push swing rod 734. The upper swing end of the flat-push swing rod 734 transmits the forward and backward movement of the push plate through the flat-push frame, causing the push plate to also move forward and backward, thereby realizing the push plate function.

[0052] Correspondingly, the flat-push plate-loading motor 71 drives the second gear 744 to rotate. The second gear 744 meshes with the first gear 743 for transmission. The two first gears 743 and the two second gears 744 are respectively mounted on the plate-loading seat in a rotatable manner. The first gear 743 abuts against the plate-loading curved cam 741 at the bottom of the plate-supporting plate 74 through the lifting crank 742 fixed on it. In this way, the flat-push plate-loading motor 71 drives the plate-supporting plate to lift and lower to realize the plate-loading function.

[0053] like Figure 6 As shown, after the mahjong machine completes the card storage, the upper and lower layers of mahjong tiles 75 are arranged on the tile receiving plate 72; when the tiles are pushed on, as... Figure 7 As shown, the tile-holding plate 74 descends to the same height as or slightly lower than the tile-receiving plate 72, in preparation for receiving the mahjong tiles on the tile-receiving plate 72; as Figure 8As shown, the pusher plate 73 pushes forward, pushing the upper and lower layers of mahjong tiles 75 on the receiving plate 72 onto the supporting plate 74. The pusher plate 73 has a stepped surface, which ensures that the upper and lower layers of mahjong tiles are neatly arranged when the push stops, effectively avoiding the uneven arrangement of the mahjong tiles caused by the upper layer's inertia due to low friction. Figure 9 As shown, after the card-pushing board 73 completes the card-pushing action, it returns to its initial position, as... Figure 10 As shown, the tile-carrying plate 74 rises and lifts the neatly arranged upper and lower layers of mahjong tiles onto the mahjong machine table, thus completing the entire flat-push tile-loading process.
