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 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 CN109381855A, CN109794059A, and CN112023390A disclose a large windmill-shaped mahjong machine. The flat-push tile-loading device is tilted relative to the side of the tabletop, and the tilted, windmill-shaped tile wall is further outwards than that of a slope-loaded windmill-shaped mahjong machine. Generally, players still need to manually push the tile wall in a little to make it suitable for playing, which is inconvenient. The main reason for this 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-raising plate from pushing further inwards, otherwise it would excessively encroach on the shuffling space, significantly reducing the maximum size of the mahjong tiles that can be used in the machine.

[0004] To address this, patent documents CN117982870A, CN117982871A, and CN117982868A disclose a mahjong machine and its flat-push card-feeding device. By hollowing out part or all of the inner wall of the card-feeding device's card-feeding base near the shuffling tray, the edge of the shuffling tray can be extended 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. In this way, most of the card-receiving plate and a small portion of the card-receiving plate are located above the shuffling frame. This not only increases the size of the shuffling tray but also effectively increases the shuffling space and 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 card-pushing device and the card-feeding inlet of the flat-push card-feeding device, reducing interference and restrictions on the shuffling tray and shuffling space by the flat-push card-feeding device and the card-feeding device, thus maximizing the size of the shuffling frame and the shuffling tray. In the aforementioned prior art, the card-holding plate transmission mechanism includes: a card-holding curved cam, two card-holding curved cams are respectively installed on the left and right sides of the bottom of the card-holding plate, and the left and right ends of the bottom of the card-holding plate are slidably connected to the card-holding seat through two guide shafts or sliding sleeves; a card-holding rocker arm, two card-holding rocker arms are respectively engaged with two card-holding curved cams for movement; a card-holding rocker arm shaft, the card-holding rocker arm shaft is rotatably installed on the card-holding seat, and the two card-holding rocker arms are respectively fixed on the two card-holding rocker arm shafts; a card-holding drive cam, the card-holding drive cam is installed on the card-holding seat and driven to rotate by a flat-push card-holding motor; a card-holding connecting rod, the card-holding connecting rod is driven to move by the card-holding drive cam; the card-holding connecting rod drives the two card-holding rocker arm shafts to rotate synchronously, thereby driving the card-holding plate to move up and down by driving the two card-holding rocker arms to rotate. 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, reducing the encroachment of the card-supporting plate transmission mechanism on the shuffling space. This allows for a larger diameter of the shuffling plate and increased shuffling space, improving shuffling efficiency and reducing the likelihood of mahjong tiles colliding with each other on the shuffling plate, thus reducing shuffling noise. However, the suspended placement of the card-adding rocker arm shaft and cam linkage drive mechanism results in insufficient support strength and weak load-bearing capacity of the card-supporting plate. Furthermore, the linkage movement is prone to obstruction, the two card-adding rocker arms experience uneven force distribution, and the stability and synchronization of their movements are poor, making installation, maintenance, and debugging more difficult. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides a mahjong machine and its flat-push card-loading device, which increases the torque transmission capacity and load-bearing capacity, improves the support strength of the card-supporting plate, has a more reasonable transmission structure, more reliable lifting action, and is more convenient for maintenance and installation.

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

[0007] A mahjong machine's flat-push tile-feeding device includes a tile-feeding base, a tile-receiving plate for receiving multiple stacks of mahjong tiles, a tile-supporting plate for simultaneously feeding 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 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-feeding curved cams, which are respectively installed on the left and right sides of the bottom of the tile-supporting plate, and each cam has a tile-feeding curved cam groove; and two tile-feeding rocker arms, which are respectively...

[0008] Preferably, during the lifting and lowering of the license plate, the two license plate lifting arms rotate synchronously in opposite directions, and the first gear rotates synchronously in opposite directions.

[0009] Preferably, a first roller is mounted on the first gear, and a cam groove is provided on the license plate drive component. The first gear moves in conjunction with the license plate drive component through the first roller and the cam groove, thereby driving the license plate drive component to move back and forth.

[0010] Preferably, the two first gears mesh with each other and rotate synchronously, with one of the first gears being driven to rotate by a flat-push motor.

[0011] Preferably, the license plate drive is equipped with a second roller, and the license plate swing arm is provided with a sliding groove. The license plate drive works with the license plate swing arm through the second roller and the sliding groove to drive the license plate swing arm to rotate.

The upper end of the flat-push swing rod is movably connected to the flat-push slider, and 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, and the swing end of the flat-push rocker arm is movably engaged with the flat-push cam through a roller. Thus, the card-pushing 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] As a preferred embodiment, a mahjong machine employing the aforementioned flat-push tile-adding device is included.

[0017] Because the present invention adopts the above technical solution, it uses a gear transmission mechanism, installs the plate-raising pulley groove on the plate-raising rocker arm shaft and transmits it through the plate-raising connecting rod, which improves stability and synchronization, increases transmission capacity and load-bearing capacity, enhances the support strength of the plate-raising plate, makes the transmission structure more reasonable, makes the lifting and lowering of the plate-raising plate smoother and more reliable, makes installation and debugging more convenient, and makes maintenance and disassembly more convenient.

[0041] Example 1:

[0042] like Figure 1 and Figure 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 on the tile-receiving plate 72 onto the tile-supporting plate 74. 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 be raised and lowered. The tile-pushing plate 73 is located outside the tile-receiving plate 72 and pushes the tiles from the outside to the inside. In a preferred embodiment, the flat-push card-adding device further includes a card-adding seat 70 and a flat-push card-adding motor 71. A card-receiving plate 72 is fixedly mounted on the card-adding seat 70, and a card-adding transmission mechanism is provided on the card-adding seat 70. The flat-push card-adding motor 71 drives the card-pushing plate 73 to move horizontally and the card-supporting plate 74 to move vertically through the card-adding transmission mechanism. The card-adding transmission mechanism includes a card-supporting plate transmission mechanism for driving the card-supporting plate 74 to move vertically and a card-pushing plate transmission mechanism for driving the card-pushing plate 73 to move horizontally. In other embodiments, the card-receiving plate 72 may also be mounted on the card-adding seat 70 in a way that allows it to move vertically and is driven to move vertically by the flat-push card-adding motor 71.

[0043] In this example, one end of the card-holding plate 72 extending along the length direction is the card inlet of the card storage channel. A card-holding block of the card-pushing device is provided outside the card inlet. The other end of the card-holding 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.

[0044] In this preferred embodiment, such as Figures 1 to 3 As shown, the plate-carrying transmission mechanism includes:

[0045] 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;

[0046] Two license plate mounting rocker arms 743 are respectively coordinated with two license plate mounting curved cams 744 for movement;

[0047] Two card-mounting rocker arm shafts 745 are rotatably mounted on the card-mounting base 70. The card-mounting rocker arm 743 is fixedly connected to the card-mounting rocker arm shaft 745 or integrally formed.

[0048] Two license plate mounting arms 746 are fixedly connected to or integrally formed with the license plate rocker arm shaft 745;

[0049] Two license plate drive components 747 are mounted on the license plate holder 70 in a reciprocating manner. The two license plate drive components 747 are respectively movably connected to two license plate swing arms 746, thereby driving the license plate swing arms 746 to rotate.

[0050] Two first gears 748 are rotatably mounted on the license plate holder 70. The two first gears 748 are movably connected to two license plate drive components 747 through cam grooves 7482, thereby driving the license plate drive components 747 to reciprocate. The two first gears 748 are driven to rotate synchronously by a flat-push license plate motor 71.

[0051] In this way, by adopting a gear transmission mechanism, the plate-loading pulley groove is installed on the plate-loading rocker arm shaft and transmitted through the plate-loading connecting rod, resulting in better stability and synchronization, easier installation and debugging, and easier maintenance and disassembly.

[0052] 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.

[0053] In this preferred embodiment, a first roller 7481 is mounted on the first gear 748, and a cam groove 7482 is provided on the license plate drive component 747. The first gear 748 moves in conjunction with the license plate drive component 747 through the first roller 7481 and the cam groove 7482, thereby driving the license plate drive component 747 to move back and forth.

[0054] In this preferred embodiment, the two first gears 748 mesh with each other and rotate synchronously, and one of the first gears 748 is driven to rotate by a flat-push motor 71.

[0055] In this preferred embodiment, a second roller 7462 is mounted on the card-adding drive component 747, and a sliding groove 7461 is provided on the card-adding swing arm 746. The card-adding drive component 747 drives the card-adding swing arm 746 to rotate through the cooperation of the second roller 7462 and the sliding groove 7461. This not only reduces the encroachment and impact of the card-adding swing arm and gear transmission mechanism on the shuffling space, but also makes the transmission structure more stable and reliable.

[0056] In this preferred embodiment, the card-loading rocker arm 743, the card-loading rocker arm seat 7451, and the card-loading swing arm 746 are sequentially fixed on the card-loading rocker arm shaft 745 from front to back, and the card-loading rocker arm seat 7451 is fixed on the card-loading seat 70.

[0057] In this preferred embodiment, a translational pulley 7472 is installed on the license plate holder 70, and a translational pulley groove 7471 is provided on the license plate drive component 747. The license plate drive component 747 achieves reciprocating movement through the sliding cooperation between the translational pulley groove 7471 and the translational pulley 7472.

[0058] In this preferred embodiment, a sliding seat 7473 is installed on the license plate holder 70, and the license plate driving component 747 slides through the sliding seat 7473 to achieve reciprocating movement. This ensures the stability of the license plate driving component 747 during movement.

[0059] 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 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.

[0060] In this preferred embodiment, the operation process of the flat-push plate-applying device is as follows:

[0061] Since the two license plate issuing rocker arms 743 have the same structure and swing principle, only the installation position is different, this embodiment will take the right license plate issuing rocker arm 743 as an example for detailed description, and the left license plate issuing rocker arm 743 will not be described in detail.

[0062] like Figure 3 As shown, the plate holder 74 is at its highest position at this time. When the first gear 748 rotates, the first roller 7481 rotates along with the first gear 748. When the first roller 7481 rotates from section a of the cam groove 7482 to section b, the translation pulley 7472 translates from section c of the translation pulley groove 7471 to section d. In this way, the plate-mounting drive component 747 translates and drives the plate-mounting swing arm 746 to swing from the left to the right. At this time, the plate-mounting rocker arm shaft 745 and the plate-mounting rocker arm 743 rotate synchronously. The roller at the end of the plate-mounting rocker arm 743 moves from section e of the plate-mounting curved cam groove 7441 to section f, until it moves to the position shown in the image. Figure 4 In the state shown, the tile-supporting plate 74 is at its lowest position. Then, the tile-pushing plate 73 pushes the mahjong tile wall on the tile-receiving plate 72 from the outside to the inside onto the tile-supporting plate 74. After pushing the tiles, the first gear 748 continues to rotate, and the first roller 7481 rotates with the first gear 748. When the first roller 7481 rotates from section b of the cam groove 7482 back to section a, the translation pulley 7472 translates from section d of the translation pulley groove 7471 back to section c. In this way, the tile-loading drive component 747 drives the tile-loading swing arm 746 to swing from the right side back to the left side, and the roller at the end of the tile-loading swing arm 743 moves from section f of the tile-loading curved cam groove 7441 back to section e, until it moves to the position shown. Figure 2As shown, the tile support plate 74 is at its highest position, thus completing one raising and lowering process of the tile support plate 74 to load tiles. The mahjong tile wall is raised to the tabletop, where the tiles can be played.

[0063] This embodiment also discloses a mahjong machine using the above-mentioned flat-push tile-adding device.
