Description

Technical Field

[0001] This utility model belongs to the field of mahjong machine technology, specifically relating to a mahjong machine card-loading device. Background Technology

[0002] Mahjong, a recreational game originating in China, is loved by the masses. With the popularity of fully automatic mahjong tables, pioneered in Japan, the traditional manual shuffling and tile arrangement method has become outdated. Modern automatic mahjong tables require two sets of magnetic mahjong tiles. One set is used by the player on the table, while the other set is shuffled and stacked inside the table for later use. After a game, the player simply operates the automatic mahjong table's program to push the completed magnetic tiles from the table back into the table. The pre-arranged tiles inside the table are then lifted to the tabletop via a lifting mechanism, allowing the game to continue. This cycle is both fast and labor-saving.

[0003] Chinese patent document CN212522972U discloses a mahjong machine tile loading mechanism, comprising: a tile-bearing bracket for supporting mahjong tiles; a tile-lifting device located on one side of the tile-bearing bracket for lifting the mahjong tiles onto the mahjong machine tabletop; a tile-straightening plate provided on the tile-lifting device; the tile-straightening plate being adapted to straighten the mahjong tiles on the tile-bearing bracket as it descends with the tile-lifting device; a tile-pushing device located on the other side of the tile-bearing bracket for pushing the mahjong tiles on the tile-bearing bracket onto the tile-lifting device; and a movable baffle located on one side of the tile-bearing bracket and between the tile-lifting device and the tile-bearing bracket. This mahjong machine tile loading mechanism uses four tile-lifting plates fixed together to form a windmill shape, allowing the mahjong tiles to be drawn in the commonly used tile-drawing pattern when they are lifted onto the tabletop, eliminating the need for tidying and enabling immediate tile drawing. Simultaneously, the tile-straightening plate on the tile-lifting device straightens the mahjong tiles on the tile-bearing bracket as it descends with the tile-lifting device, solving the problem of tiles getting stuck during tile lifting.

[0004] In the mahjong machine card-feeding mechanism described in the aforementioned patent literature, the lifting plate and the card-feeding seat rely solely on the cooperation of guide pillars and guide sleeves to guide the lifting plate's upward and downward movement. However, the cooperation accuracy of the guide pillars and guide sleeves is affected by their machining accuracy. In particular, after the lifting plate carries the mahjong tiles, the pushing weight increases, and the coaxiality of the guide pillars and guide sleeves cannot be guaranteed during the card-feeding process. This leads to problems such as the lifting plate swaying left and right and unstable card-feeding, resulting in the inability to maintain a uniform gap between the lifting plate and the card-feeding opening, and even interference between the lifting plate and the tabletop.

[0026] like Figures 1-7 As shown, this embodiment provides a mahjong machine tile-loading device, including a tile-lifting plate 1, a guide plate 2, and a drive mechanism 3 for driving the lifting plate 1 to move up and down. Guide plates 2 are provided at both ends of the lifting plate 1 to facilitate its movement, allowing it to smoothly push the mahjong tiles onto the tabletop. Figure 2 As shown, the bottom of the tile-raising plate 1 is provided with a guide post 12, and the mahjong machine is provided with a guide sleeve 13 that slides with the guide post 12.

[0027] Both ends of the tile-raising plate 1 are equipped with sliders 4, and lifting gears 5 are rotatably mounted on the sliders 4; the guide plate 2 is installed on the mahjong machine, and a guide assembly is provided between the guide plate 2 and the sliders 4, allowing the sliders 4 to slide in cooperation with the guide plate 2 through the guide assembly, such as... Figure 6 As shown, the guide plate 2 is provided with a rack 6 that is adapted to the lifting gear 5. The lifting gear 5 and the rack 6 mesh with each other to improve the lifting stability of the lifting plate 1.

[0028] Mahjong machines typically have four tile-lifting plates 1, each equipped with two guide plates 2. Driven by the drive mechanism 3, the tile-lifting plates 1 utilize the guiding components between the guide plates 2 and the slider 4, as well as the cooperation between the lifting gear 5 and the rack 6, to achieve linear lifting and lowering motion, thus ensuring smooth lifting and lowering of the tile-lifting plates 1 and effectively solving the problem of left and right swaying during lifting and lowering. In addition, after the tile-lifting plates 1 have risen to their positions, they maintain good alignment accuracy with the tile-lifting opening of the tabletop, preventing interference between the tile-lifting plates 1 and the tile-lifting opening of the tabletop when they have risen to their positions.

[0029] like Figure 3 and Figure 6As shown, specifically, the guiding assembly includes a first guide strip 7 and a first guide groove 8 that are slidably connected.
