Description

Technical Field

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

[0002] Mahjong is widely enjoyed by the public as a recreational activity and has also been recognized as 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 announcement numbers CN205832565U, CN206577363U, and CN207627889U disclose a flat-push tile-loading device for a traditional four-player mahjong machine. The device includes a tile-receiving plate for receiving and arranging multiple stacks of mahjong tiles, a tile-supporting plate for delivering multiple stacks of mahjong tiles onto the table at once, and a tile-pushing plate for pushing the multiple stacks of mahjong tiles from the tile-receiving plate to the tile-supporting plate. The tile-receiving plate forms a tile storage channel for storing and arranging multiple stacks of mahjong tiles. The tile-supporting plate is located inside the tile-receiving plate and can be raised and lowered. The tile-pushing plate is located outside the tile-receiving plate and pushes the tiles from the outside to the inside. The flat-push card-feeding device also includes a card-feeding base and a flat-push card-feeding motor. The card-bearing plate is fixedly mounted on the card-feeding base, which is equipped with a card-feeding transmission mechanism. The flat-push card-feeding motor drives the card-pushing plate to move horizontally and the card-supporting plate to rise and fall through the card-feeding transmission mechanism. The card-feeding transmission mechanism includes a card-supporting plate transmission mechanism for driving the card-supporting plate to rise and fall and a card-pushing plate transmission mechanism for driving the card-pushing plate to move horizontally. However, in the existing structure, the card-supporting plate is slidably connected to the card-feeding base (grid plate) by two card-feeding guide shafts fixed to its bottom. When the card-supporting plate descends to the bottom, the lower end of the card-feeding guide shaft will extend downwards and press against the bottom plate. It may even be necessary to make holes in the bottom plate so that the card-feeding guide shaft can pass through the bottom plate. This not only results in a thicker mahjong machine core, making it impossible to make an ultra-thin machine, but also affects the strength of the bottom plate, increases manufacturing costs, makes the internal core of the machine susceptible to contamination, and poses safety risks. Summary of the Invention

[0004] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a mahjong machine and its flat-push card-feeding device, which fixes the card-feeding guide shaft on the card-feeding seat and the guide sleeve on the card-supporting plate. In this way, when the card-supporting plate descends to the bottom, the card-feeding guide shaft will not hit the bottom plate, which can make an ultra-thin mahjong machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] 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 on the receiving plate onto 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 to the inside. The receiving plate is fixedly mounted on the tile holder. The tile guide shaft of the supporting plate is fixedly connected to or integrally formed on the tile holder, the tile delivery holder, the shuffling tank, or the base plate. A tile guide sleeve is sleeved on the tile guide shaft. The tile guide sleeve is fixedly connected to the supporting plate and moves up and down synchronously with the supporting plate.

[0007] Preferably, the left and right sides of the plate holder are provided with plate guide shaft seats, and the plate guide shaft is fixedly mounted on the plate guide shaft seats.

[0008] Preferably, the device also includes a horizontal pushing card-adding motor, which drives the card-adding plate to move horizontally and the card-supporting plate to lift and lower the card-adding plate via a card-adding transmission mechanism; the card-adding transmission mechanism includes a card-supporting plate transmission mechanism for driving the card-supporting plate to lift and lower the card-supporting plate and a card-adding plate transmission mechanism for driving the card-adding plate to move horizontally.

[0009] Preferably, the plate-carrying transmission mechanism includes:

[0010] Two license plate feeding cams are installed on the left and right sides of the bottom of the license plate support plate, respectively.

[0011] Two card-loading rocker arms, each of which moves in coordination with two card-loading curved cams;

[0012] Two first gears are mounted on the card holder in a rotatable manner. The first gears are fixedly connected to the card holder rocker arm or integrally formed. The two first gears are driven to rotate synchronously by a flat-push card holder motor.

[0013] Preferably, it also includes two second gears, which mesh with each other and rotate synchronously. The two second gears mesh with two first gears respectively, and one of the second gears is driven to rotate by a flat-push motor.

[0014] Preferably, during the lifting and lowering of the license plate, the two license plate lifting arms rotate synchronously in opposite directions, and the two first gears rotate synchronously in opposite directions.

[0015] Preferably, the card-pushing plate transmission mechanism includes a card-pushing frame, a flat-push slider, a flat-push cam, and a flat-push swing rod. The flat-push slider slides back and forth on the card-pushing frame along the guide rod. The card-pushing plate is fixed on the flat-push slider. The upper end of the flat-push swing rod is movably connected to the flat-push slider. The lower end of the flat-push swing rod is hinged to the upper card holder through the flat-push swing rod 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. One second gear is driven to rotate by the flat-push card-feeding motor, and the other second gear is coaxially fixed and rotates synchronously with the flat-push cam. Thus, the flat-push card-feeding motor drives the flat-push slider to slide back and forth through the flat-push cam and the flat-push swing rod to push the card.

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

[0017] Preferably, four sets of tile-picking and transporting systems are arranged around the shuffling tray. Each tile-picking and transporting system includes a tile-feeding device for picking up and sending out mahjong tiles one by one from the shuffling tray, and a tile-pushing device for pushing the mahjong tiles sent out by the tile-feeding device into the flat-push tile-loading device. The flat-push tile-loading device is used to send multiple stacks of mahjong tiles onto the mahjong machine table at once. The mahjong machine table has four tile-loading openings, which are arranged parallel to the four side edges of the table. The four tile-supporting plates in the four sets of tile-picking and transporting systems cooperate with the four tile-loading openings. When the tile-supporting plates are raised, they fill the tile-loading openings.

[0018] Preferably, in the same group of card picking and handling system, one of the card-loading guide shafts of the card tray is located between its inner end and the card-feeding device, and the card-loading guide shaft is located on one side of the card outlet of the card-feeding device.

[0019] Because this utility model adopts the above technical solution, the card-raising guide shaft is fixed on the card-raising seat and the guide sleeve is fixed on the card-supporting plate. In this way, the length of the card-raising guide shaft only needs to be slightly greater than the lifting height of the card-supporting plate. When the card-supporting plate descends to the bottom, it will not extend downwards beyond the bottom surface of the card-raising seat, nor will it press against or pass through the bottom plate. This allows the mahjong machine mechanism to be made thinner, which is especially suitable for ultra-thin machines. Attached Figure Description

The specific structure of the horizontal plate-mounting device can be found in various embodiments disclosed in patent documents such as CN109381855A, CN109794059A, CN112023390A, CN114247127A, CN114146397A, and CN117982871A.

[0040] This utility model is preferably preferred, such as Figure 3 and Figure 4As shown, the two card-raising guide shafts 741 of the card-supporting plate 74 are fixedly connected or integrally formed on the card-raising base 70. A card-raising guide sleeve 740 is fitted on the card-raising guide shaft 741. The card-raising guide sleeve 740 is fixedly connected to the card-supporting plate 74 and rises and falls synchronously with the card-supporting plate 74. In this way, the length of the card-raising guide shaft 741 only needs to be slightly greater than the lifting height of the card-supporting plate 74. It will not extend downwards to the bottom surface of the card-raising base, nor will it press against or pass through the bottom plate. This allows the mahjong machine mechanism to be made thinner, which is especially suitable for ultra-thin machines.

[0041] In this preferred embodiment, card-raising guide shaft seats 704 are provided on the left and right sides of the card-raising seat 70, and the card-raising guide shaft 741 is fixedly mounted on the card-raising guide shaft seats 704. This makes the load-bearing structure of the card-supporting plate more balanced, and the lifting and guiding positioning references on both the inner and outer sides of the card-supporting plate are on the card-raising seat, making installation and debugging more convenient and the lifting action more stable and reliable. In other embodiments, the card-raising guide shaft seats 704 can also be directly fixed to the base plate 1 or the card-feeding seat, or integrally formed with the card-feeding seat, or fixedly connected to or integrally formed with the four-sided integrally formed shuffling bucket.

[0042] In this preferred embodiment, within the same group of card picking and handling systems, a card-loading guide shaft 741 of the card-supporting plate 74 is disposed between its inner end and the card-feeding device 5, and this card-loading guide shaft 741 is located on one side of the card outlet of the card-feeding device 5. This allows for full utilization of the gap between the card-supporting plate and the card-feeding device, resulting in a reasonable structure and stable and reliable lifting of the card-supporting plate.

[0043] In this preferred embodiment, the plate-carrying transmission mechanism includes:

[0044] Two plate-mounting curved cams 744 are respectively installed on the left and right sides of the bottom of the plate-holding plate 74;

[0045] Two license plate mounting rocker arms 743 are respectively coordinated with two license plate mounting curved cams 744 for movement;

[0046] Two first gears 748 are rotatably mounted on the card holder 70. The first gears 748 are fixedly connected to or integrally formed with the card holder rocker arm 743. The two first gears 748 are driven to rotate synchronously by the flat-push card holder motor 71.

[0047] In this preferred embodiment, two second gears 747 are also included. The two second gears 747 mesh with each other and rotate synchronously. The two second gears 747 respectively mesh with two first gears 748 for transmission. One of the second gears 747 is driven to rotate by a flat-push motor 71. Such a gear transmission mechanism has a reasonable structure, smooth movement, large torque transmission, and is more convenient for installation and maintenance.

[0048] 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 748 rotate synchronously in opposite directions. This results in a reasonable lifting and lowering structure for the plate holder 74 and smooth movement.

[0049] In this preferred embodiment, 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 second gear 747 is driven to rotate by the flat-push card-feeding motor 71, and the other second gear 747 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.

[0050] In other embodiments, the card-carrying plate transmission mechanism and the card-pushing plate transmission mechanism may also refer to various embodiments disclosed in patent documents such as CN109381855A, CN109794059A, CN112023390A, CN114247127A, CN114146397A, and CN117982871A.
