Technical Field

[0002] Automatic mahjong machines usually have functions such as shuffling, stacking, pushing, and raising cards, which are convenient and labor-saving to use. Among them, stacking, pushing, and raising are the most important steps. Therefore, in order to ensure the normal operation of these functions, most of them are controlled by independent motors. However, due to the excessive number of motors, the assembly is cumbersome, the structure is complex, the production efficiency is low, and the cost is high. At the same time, when pushing and raising cards are linked, there are many linkage parts, which occupy a large area. Moreover, they may become loose after long-term use, affecting the normal operation of the mahjong machine.

[0003] In order to address the shortcomings of the existing technology, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses an integrated structure for stacking, pushing and raising cards and a mahjong machine [202010463907.7], which includes a drive motor, a stacking structure, a pushing structure and a raising structure. The output shaft of the drive motor is provided with two one-way bearings arranged side by side, and the free rotation directions of the two one-way bearings are opposite; the stacking structure is connected to the drive motor through a first transmission mechanism, the pushing structure is connected to the drive motor through a second transmission mechanism, and the raising structure is connected to the drive motor through a third transmission mechanism.

[0004] The above solution has solved the problem of complicated assembly and low production efficiency caused by the excessive number of existing motors to a certain extent. However, the solution still has many shortcomings, such as a large number of linkage components, a large occupied area, and loosening after long-term use. Summary of the Invention
