Description

Technical Field

[0001] This utility model relates to the technical field of mahjong machines, and in particular to a tile blocking mechanism and a mahjong machine. Background Technology

[0002] The tile-pushing mechanism of a mahjong machine is a complex and precise mechanical system. It works in concert with motor drive, power transmission, tile lifting and pushing devices, and tile support to automatically push the mahjong tiles. In automatic mahjong tables, the tile-pushing mechanism typically works in conjunction with the shuffling mechanism and the tile-collecting mechanism to achieve automatic shuffling, tile collection, and tile pushing. These functions allow players to play mahjong more conveniently and quickly, enhancing the game's fun and ease of use. The tile-pushing mechanism is a crucial component of the mahjong machine, responsible for pushing the shuffled and stacked mahjong tiles from the stacking plate onto the tile-lifting plate. As the plate rises, the mahjong tiles are placed on the tabletop.

[0003] Chinese invention patent CN102133480A, published on July 27, 2011, discloses a fully automatic mahjong machine. This invention includes a card-feeding system, a card-adding system, a card-raising system, and a shuffling tray. The card-feeding system comprises four card-feeding mechanisms, each including a transmission frame and a card-feeding motor, a card-suction wheel, a conveyor belt, a conveyor table, a card-in guide plate, and a card-out guide plate fixed to the transmission frame. The upper end of the conveyor table is the card-feeding channel. The card-suction wheel is close to the lower end of the card-in port of the card-feeding channel. The card-in guide plate is located above the card-suction wheel, and the card-out guide plate is located at the card-out port of the card-feeding channel. The card-feeding motor drives the motor guide wheel, which is located below the conveyor table. The conveyor belt surrounds the motor guide wheel, the card-suction wheel, and the conveyor table. The patented tile-lifting plate lifts the tiles when it is tilted. When the tile-lifting plate is rotated to a horizontal position, the mahjong tiles are lifted off the table. However, because the tile-lifting plate is tilted, the mahjong tiles are also tilted, and they may slip off during the tile-lifting process.

[0004] Therefore, it is necessary to propose a tile-blocking mechanism and a mahjong machine to prevent the mahjong tiles from slipping off during the tile-raising process. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a card blocking mechanism and a mahjong machine, which aims to solve the technical problem that mahjong tiles may slip during the raising process in the prior art.

[0006] To achieve the above objectives, this utility model proposes a sign-blocking mechanism, including a tilting sign-raising plate with a rotating hole, the sign-raising plate rotating along the axis of the rotating hole; characterized in that: a rotating plate is provided on the side of the sign-raising plate away from the rotating hole, the rotating plate having an arc groove; further comprising a baffle plate with a slider disposed within the arc groove; and a stop bar provided on the baffle plate in the height direction.

[0007] Preferably, the device includes a housing, on which a mounting groove for mounting the baffle is provided.

[0008] Preferably, the housing is provided with an inclined seat on the side near the rotating hole, the inclined seat is provided with an inclined plate, and the inclined seat is provided with a moving groove distributed along the inclined plate.

[0009] Preferably, the side of the lifting plate away from the rotating hole is provided with a through groove for the raising and lowering of the stop bar.

[0010] Preferably, the device also includes a lifting baffle, which is provided with a push-pull groove and a lifting groove; the baffle is provided with a push-pull shaft, which is disposed in the push-pull groove; the housing is provided with a groove for the lifting baffle to move up and down, and the groove is provided with a lifting shaft that passes through the lifting groove.

[0011] Preferably, the lifting slots are inclined and there are two or more of them.

[0012] To achieve the above objectives, this utility model proposes a mahjong machine that uses the aforementioned tile-blocking mechanism.

[0013] Compared with the prior art, the beneficial effects of the card-blocking mechanism and mahjong machine provided by this utility model are as follows:

[0014] 1. Due to the presence of baffles and barriers, the mahjong tiles will not slip off the lifting plate during the tilting and lifting process.

[0015] 2. The lifting baffle prevents the mahjong tiles from falling into the bottom of the lifting plate and getting stuck during the stacking process. When the lifting plate descends, the lifting baffle also descends, allowing the mahjong tiles to be pushed smoothly onto the lifting plate.

[0016] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

[0028] See Figure 1 This utility model embodiment provides a mahjong machine. The lifting plate 1 of the mahjong machine tilts after the mahjong tiles are stacked on it before rising to a horizontal position on the table. During the tilting process, the mahjong tiles can easily slip off the lifting plate 1. To prevent this, a blocking mechanism is provided on the tilted side of the lifting plate 1, preventing the mahjong tiles from slipping off during the process of rising to the table.

[0029] The following is an introduction to the sign-blocking mechanism:

[0030] In this embodiment, the lifting plate 1 operates as follows during the lifting process: Figure 1 For example, initially, it is at its highest position, level with the mahjong table. When preparing to place a tile, the tile-raising plate 1 first rotates around one side and tilts. Then, the tile-raising plate 1 moves to the left, and the entire tile-raising plate 1 is in its lowest position, remaining horizontal.

[0031] See Figure 1-2In an optional embodiment, a sign-blocking mechanism includes a tilting sign-raising plate 1 with a rotating hole 11, the sign-raising plate 1 rotating along the axis of the rotating hole 11; a rotating plate 12 with an arc groove 121 on the side of the sign-raising plate 1 away from the rotating hole 11; a baffle 2 with a slider 21 disposed in the arc groove 121; and a stop bar 22 in the height direction of the baffle 2.

[0032] Specifically, when the lifting plate 1 descends, one side first rotates along the axis of the rotating hole 11, tilting to its lowest position. The rotating hole 11 is a cylindrical hole, and its axis is the central axis of the cylindrical hole. The arc groove 121 is an arc centered on the central axis of the rotating hole 11. During the rotation of the lifting plate 1, the slider 21 moves within the arc groove 121, and the baffle 2 does not change position. Due to the presence of the baffle 2, tiles cannot be placed from that side. In this design, the other side of the lifting plate 1 also descends to its lowest position to keep the lifting plate horizontal. Then, the tile-pushing mechanism pushes the mahjong tiles onto the lifting plate 1, with the tile placement position along the length of the lifting plate 1.

[0033] See Figure 4 and Figure 5 In an optional embodiment, the housing 3 is provided with an inclined seat 32 on the side near the rotating hole 11, the inclined seat 32 is provided with an inclined plate 321, and the inclined seat 32 is provided with a moving groove 322 distributed along the inclined plate 321.

[0034] Specifically, the lifting plate 1 first rotates around the axis of the rotating hole 11, with one side descending to its lowest point first. Then, the lifting plate 1 moves to the left and slowly descends along the inclined plate 321, with that side also descending to its lowest point. Bearings are provided on both sides of the rotating hole 11 of the lifting plate 1, and the bearings cooperate with the moving grooves 322 on both sides of the inclined plate 321, making descent easier and reducing resistance.

[0035] See Figure 4 In an optional embodiment, a housing 3 is included, on which a mounting groove 31 for mounting the baffle 2 is provided. The lifting plate 1 first rotates around the axis of the rotating hole 11. When one side descends to its lowest point, the slider 21 is positioned above the arc groove 121. As it moves along the inclined plate 321 on the other side, the baffle 2 also moves along with the inclined plate 321. For ease of movement, the baffle 2 moves within the mounting groove 31.

[0036] See Figure 2 In an optional embodiment, the lifting plate 1 has a through groove 13 on the side away from the rotating hole 11 for raising and lowering the stop bar 22. The through groove 13 can bring the mahjong tile and the stop bar 22 closer together, preventing the mahjong tile from slipping.

[0037] See Figure 2 , Figure 3 and Figure 4 In an optional embodiment, a lifting baffle 4 is further included, which is provided with a push-pull groove 41 and a lifting groove 42. A push-pull shaft 23 is provided on the baffle 2, which is disposed in the push-pull groove 41; a groove 33 is provided on the housing 3 for the lifting baffle 4 to move up and down, and a lifting shaft 34 is provided on the groove 33 that passes through the lifting groove 42.

[0038] Specifically, the lifting plate 1 first rotates around the axis of the rotating hole 11, with one side descending to its lowest point. As it moves along the inclined plate 321 on the other side, the baffle 2 also moves along with the inclined plate 321. At this time, the push-pull shaft 23 moves with the inclined plate 321 to its leftmost position (from...). Figure 3 (See) At this moment, the lifting plate 1 is not yet at a horizontal position. The lifting plate 1 continues to move along the inclined plate 321, and the push-pull shaft 23 will drive the lifting baffle 4 to move to the left. Since the lifting groove 42 and the lifting shaft 34 are engaged at the bottom, the lifting baffle 4 will move diagonally downward. When the lifting plate 1 is horizontal at the lowest point, the lifting baffle 4 will not be higher than the stacking plate. At this time, the stacking plate and the lifting plate are at the same height. The pushing mechanism pushes the mahjong tiles onto the lifting plate. Then, one side of the rotating hole of the lifting plate first rises along the inclined plate 321 to the highest position, and then the other side rotates to lift the mahjong tiles onto the table. The lifting baffle 4 also rises higher than the stacking plate again to prevent the mahjong tiles from falling into the bottom of the lifting plate 1 during the stacking process and to prevent them from getting stuck.

[0039] See Figure 3 In an optional embodiment, the lifting groove 42 is inclined and there are two or more. Preferably, there are two lifting grooves 42, which are respectively arranged on both sides of the lifting baffle 4, so that the force is more evenly distributed.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
