Description

Technical Field

[0001] The utility model belongs to the technical field of mahjong machine equipment, and particularly relates to a rotary card pushing structure of a mahjong machine. Background Art

[0002] In an automatic mahjong machine, the pusher mechanism is a crucial component. The machine first uses a card feeder to sequentially transport mahjong tiles into a storage channel, where the pusher lever rotates to push the tiles toward the card raising plate, completing the process of loading the tiles. Existing pushers use a pusher motor to control the pusher lever, allowing it to move within the storage channel. However, this rotational movement can cause friction and collision between the tiles and the inner wall of the storage channel, leading to jamming and a high rate of machine failure.

[0003] In order to solve the deficiencies in the existing technology, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a noise-reducing mahjong card-discharging mechanism [202020208016.2], which includes a base and an annular card storage slot, the card storage slot includes an inner ring of an inner ring pushing card barrel, an outer ring of an outer ring of a card storage slot and a card-receiving ring, the top of the base is provided with an annular track, the bottom of the inner ring pushing card barrel is provided with an annular step, the annular step matches the annular track, the inner ring of the card-receiving ring is connected to the outer wall of the bottom of the inner ring pushing card barrel; a driving motor is provided on the base, a driving gear is provided on the output shaft of the driving motor, an inner gear ring is provided at the bottom end of the inner ring pushing card barrel, the driving gear is meshed with the gear ring, the driving motor drives the gear to rotate and thereby drives the inner ring pushing card barrel and the base to rotate relative to each other; the outer wall of the inner ring pushing card barrel is provided with a card-receiving head.
