[0002] Through its complex internal mechanical structure and intelligent control system, the mahjong machine realizes the full-automatic process from shuffling, stacking, dealing to recycling cards, greatly improving the convenience and fairness of the game. Analysis of the working process of the mahjong machine: Initial shuffling: When the mahjong cards are neatly placed in the card bin of the mahjong machine, the machine is started, and the built-in shuffling system is immediately activated. Through a series of complex mechanical movements, such as stirring, flipping, etc., the mahjong cards are thoroughly shuffled to ensure that each card has an equal chance to appear in any position, thus maintaining the fairness and randomness of the game. Intelligent stacking: After the shuffling process is completed, the stacking mechanism in the mahjong machine will automatically arrange the shuffled cards neatly according to the preset arrangement rules or programs. This process not only improves the preparation efficiency of the game but also ensures the cleanliness and orderliness of the card faces, laying a good foundation for the next game. Precise dealing: After the stacking is completed, the mahjong machine will, according to the game rules and the number of participants, through a precise dealing mechanism, deal the cards one by one and accurately to each player. This step ensures that each player can obtain the same number of cards at the same time, further guaranteeing the fairness and smooth progress of the game. Automatic recycling and preparation: As a round of the game ends, players can put the cards in their hands back into the recycling slot of the mahjong machine. The internal recycling system of the machine is immediately activated, quickly and orderly collecting the cards back into the card bin and automatically preparing for the next round of shuffling and stacking. This process realizes the continuity and seamless connection of the game, allowing players to continuously enjoy the fun of mahjong.

[0041] Specifically, in the initial position, the card-lifting plate 2 is at the highest position, such asFigure 1 As shown, the connection structure of the three gears and the rack at this time is as Figure 4 shown. The motor drives the third gear 8 to rotate counterclockwise, the rack 7 moves to the left, and the card-lifting plate 2 descends to Figure 3 the state, and the connection structure of the three gears and the rack at this time is as Figure 6 shown. The mahjong enters onto the card-lifting plate 2, and the third gear 8 rotates clockwise to the initial position. Starting from the initial position, the motor drives the third gear 8 to rotate clockwise, the rack 7 moves to the right, and the card-lifting plate 2 rotates to Figure 2 the state, and the connection structure of the three gears and the rack at this time is as Figure 5 shown. Since the second gear enters the toothless section 71, the right end of the card-lifting plate does not move, and the left end rotates. Embodiment 2

[0042] A mahjong machine uses the above-mentioned card-lifting mechanism. There are four sets of linkage mechanisms in the card-lifting mechanism, and the card-lifting mechanism is controlled by one motor. Specifically, the card-lifting mechanisms are respectively located at the four corners of the mahjong table. There is a motor at the center of the mahjong table. The motor drives a large gear disk to rotate, and the gear disk meshes with the third gears in the four card-lifting mechanisms respectively or directly drives the rack 7 to move. The situation of the linkage between one rack and the gears is as follows: At the initial position, the card-lifting plate 2 is at the highest position, as Figure 1 shown, and the connection structure of the three gears and the rack at this time is as Figure 4 shown. The motor drives the third gear 8 to rotate counterclockwise, the rack 7 moves to the left, and the card-lifting plate 2 descends to Figure 3 the state, and the connection structure of the three gears and the rack at this time is as Figure 6 shown. The mahjong enters onto the card-lifting plate 2, and the third gear 8 rotates clockwise to the initial position. Starting from the initial position, the motor drives the third gear 8 to rotate clockwise, the rack 7 moves to the right, and the card-lifting plate 2 rotates to Figure 2 the state, and the connection structure of the three gears and the rack at this time is as Figure 5 shown. Since the second gear enters the toothless section 71, the right end of the card-lifting plate does not move, and the left end rotates. The functions of lifting and lowering cards are realized through the linkage structure, and the structure is more diverse and the interest is stronger.

[0043] The mahjong table has multiple card-lifting modes:

[0044] The first card-lifting mode is to lift cards together. The card-lifting plate first tilts and then becomes horizontal ( Figures 1 - 2 - Figure 1 state); The second mode is 6 stacks of cards lifted + the remaining cards lifted: For lifting 6 stacks of cards, it first tilts and then becomes horizontal, and for lifting the remaining cards, it first tilts and then becomes horizontal ( Figures 1 - 2 - Figures 1 - 2 - Figure 1mode); The third card-putting mode: 6 piles of card-putting + the remaining card-putting. The 6 piles of card-putting are horizontal up-and-down card-putting, and the remaining card-putting is first inclined and then horizontal ( Figures 1 - 3 - Figures 1 - 2 - Figure 3 ). Or, the appropriate card-putting mode can also be selected according to the actual situation.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, or improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
