When the tile lifting and pushing device of the mahjong machine is used, firstly, the contact rotating columns 21 of the driven tile lifting gear I15 and the driven tile lifting gear II 18 are respectively positioned at the first descending driving sections 26 of the driving bayonets 25 at the two sides of the lower part of the tile lifting driving frame 12, namely, the tile lifting driving frame 12 is positioned at the initial position for placing a first layer of mahjong tiles; then, a mahjong tile feeding mechanism corresponding to the tile lifting and pushing device in the mahjong machine core sequentially conveys mahjong tiles randomly sucked from the shuffling cavity to the tile supporting frame 3 at the upper part of the tile lifting driving frame 12. After the number of the mahjong tiles on the first layer on the tile supporting frame 3 meets the requirement, the driving motor 6 drives the driving motor gear 16 to rotate, drives the contact rotating columns 21 on the driven tile lifting gear I15 and the driven tile lifting gear II 18 to rotate towards the second descending driving section 27 of the driving bayonet 25, and further drives the tile supporting frame 3 on the upper portion of the tile lifting driving frame 12 to move downwards by the thickness of one mahjong tile; then, the mahjong tiles randomly sucked from the shuffling cavity are sequentially conveyed to the upper part of one layer of mahjong tiles arranged on the tile supporting frame 3 by the tile feeding mechanism, so that two layers of mahjong tile piles (shown in figure 1) arranged in a stacked mode are formed on the tile supporting frame 3.

Then, the driving motor 6 continues to drive the driving motor gear 16 to rotate, the contact rotating columns 21 on the driven tile lifting gear I15 and the driven tile lifting gear II 18 are driven to pass through the stable uncovering contact section 28 of the driving bayonet 25, and the position of the tile lifting driving frame 12 is kept motionless temporarily; meanwhile, the pushing plate rotating cam 8 rotating with the driven lifting gear ii 18 opens the inner groove section 44 of the cover plate of the annular inner groove, the cam linkage post 40 drives the pushing plate swinging arm 9 to swing upward around the swinging arm fulcrum 10, and further drives the pushing plate driving rack 11 to move upward along the rack guide sliding groove 49 of the rack guide connecting body 33, and the turning cover rotating gears 55 at the two ends of the driving transmission long shaft 34 rotate forward through the pushing plate driving gear 32 engaged with the pushing plate driving rack 11, so that the pushing plate turning cover plate 37 is opened (as shown in fig. 18 and 19), and the lifting opening at the upper edge position of the mahjong machine table surface is exposed.

After the tile pushing and turning cover plate 37 is opened, the driving motor gear 16 which rotates with the driving motor 6 drives the contact rotating columns 21 on the driven tile lifting gear I15 and the driven tile lifting gear II 18 to pass through the lifting driving section 29 of the driving bayonet 25, so as to drive the tile lifting driving frame 12 and the mahjong tile stack thereon to move upwards together, and push the mahjong tiles 5 to the upper part of the table top of the mahjong machine through the tile lifting opening at the upper edge of the table top (as shown in fig. 20 and 21). In the process, the high-position maintaining inner groove section 45 of the annular inner groove of the mahjong tile pushing rotating cam 8 rotating along with the driven mahjong tile lifting gear II 18 maintains the upward swing position of the mahjong tile pushing swing arm 9, namely, the mahjong tile pushing driving rack 11 is kept to be temporarily fixed at the high position (the mahjong tile pushing turnover cover plate 37 is in an open state, so that the mahjong tile stack can be smoothly pushed and lifted).

After the mahjong tiles rise above the table surface of the mahjong machine, the driven tile rising gear II 18 continues to drive the tile pushing rotating cam 8 to rotate, the cover plate of the annular inner groove of the tile pushing rotating cam 8 closes the inner groove section 46, the tile pushing swing arm 9 is driven to swing downwards around the swing arm fulcrum 10 through the cam linkage column 40 so as to drive the tile pushing driving rack 11 to move downwards, and the tile pushing driving gear 32 drives the flip rotating gears 55 at the two ends of the transmission long shaft 34 to rotate reversely, so that the tile pushing flip cover plate 37 is gradually closed (as shown in fig. 22 and 23). In the closing process of the tile pushing and turning cover plate 37, the contact rotating columns 21 on the driven tile lifting gear I15 and the driven tile lifting gear II 18 pass through the stable tile pushing contact section 30 of the driving bayonet 25, so that the rising state of the tile lifting driving frame 12 is maintained, and the tile pushing and turning cover plate 37 can push the rising mahjong tile stack conveniently. When the tile pushing and turning cover plate 37 is closed, the tile pushing and turning cover plate 37 is close to the edge of the cover plate on one side of the mahjong tiles 5, so that the mahjong tiles on the raised tile supporting frame 3 and above the table top of the mahjong machine can be pushed out to the middle of the table top for a certain distance. When the tile pushing and turning cover plate 37 is completely closed, the driven tile lifting gear I15 rotating along with the driving motor gear 16 and the contact rotating column 21 on the driven tile lifting gear II 18 pass through the first descending driving section 26 of the driving bayonet 25, so that the tile lifting driving frame 12 is driven to move downwards to the initial position for placing the first layer of mahjong tiles; and preparing for the next action cycle of 'card lifting and pushing forward'.
