5. A control method applicable to a modular quick-change conveyor belt tabletop push-card mahjong machine as claimed in claim 1, characterized in that the control method is:

When shuffling the cards, first scatter the mahjong tiles onto the large plate (42) of the shuffling mechanism;

When shuffling begins, the motor of the large plate (42) in the shuffling mechanism drives the large plate (42) to rotate in a clockwise direction. During the rotation of the large plate (42), the card-moving strips on the large plate (42) move the mahjong tiles toward the edge of the large plate (42);

During the card-moving process of the card-moving bar, the flipping magnets on the edge of the large plate (42) will flip all the mahjong tiles so that the words on them face upwards;

When a mahjong tile with the face down approaches the card suction mechanism, the card suction wheel (6) on the card suction mechanism will attract the mahjong tile, and then the conveyor belt (5) on the card suction mechanism will send the mahjong tile to the card feeding mechanism;

When the mahjong tiles arrive at the card feeding mechanism, the bidirectional motor (20) rotates clockwise to drive the card sinking wheel (35), and the card sinking wheel (35) drives the card sinking seat (34) during the rotation process. The card sinking seat (34) stacks two mahjong tiles into a pile and lifts them up. Then, the stacked mahjong tiles are sent into the card storage slot (12) through the card feeding rod (37) and the pushing head (39);

When the required number of mahjong tiles in the card storage slot (12) is reached, the bidirectional motor (20) stops rotating, thereby preventing excess mahjong tiles from entering the card storage slot (12);

When the mahjong tiles need to be raised, the bidirectional motor (20) will rotate counterclockwise to drive the tile raising mechanism, and the tile raising rocker arm (18) in the tile raising mechanism will raise the tile storage slot (12);

When the card-lifting rocker arm (18) reaches the highest point, the bottom of the mahjong tiles in the card storage slot (12) is exactly parallel to the tabletop. At this time, the bidirectional motor (20) will continue to rotate counterclockwise to drive the card-pushing mechanism. The bevel gear (27) in the card-pushing mechanism drives the transmission rod (26) to rotate. The transmission rod (26) then drives the card-pushing rocker arm (25) to push the card-pushing rod (31). The card-pushing rod (31) pushes the mahjong tiles in the card storage slot (12) onto the tabletop.
