The reversing wheel and the second conveying wheel are matched to enable the conveying belt running on the surface of the supporting table to descend to the surface of the card bearing table. However, when the feeding speed is too high, the continuously fed mahjong tiles may become crowded and abut against the first tile blocking plate, which requires the provision of a guide roller. After the guide roller is arranged, when the mahjong pieces on the conveying channel fall, the head ends of the mahjong pieces are firstly contacted with the guide roller, the guide roller rotates under the pressure of the mahjong pieces, the head ends of the mahjong pieces are driven to tilt upwards, and the mahjong pieces are prevented from diving and are driven to fall onto the conveying belt on the surface of the mahjong piece bearing table.

Besides controlling the start and stop of the conveyer belt to realize one-by-one card stacking by controlling the start frequency of the driving mechanism, a card blocking part can be arranged on one side of the card pushing head facing the conveying channel, and the card blocking part always props against a card outlet of the conveying channel in the card pushing process; however, when the length of the conveying channel is equal to one fourth of the total length of the mahjong tiles, the first stage of the tile stacking action does not exist, and the tile blocking part is arranged to prop against the tile outlet of the conveying channel conveniently.

As shown in fig. 5, and in combination with fig. 2 and 3, a card pushing and feeding mechanism 8 is provided at the card pushing port, and the card pushing and feeding mechanism 8 includes a card pushing head 81, where the card pushing head 81 is used to push the stacked card piers in the card stacking space into the card storing track 82 and further into the card lifting and carrying mechanism 9.
In order to ensure that the same number of mahjong tiles are conveyed by each tile taking and conveying unit 4, and avoid that the tile taking and conveying unit 4 performs complicated tile returning operation (the number of the sucked mahjong tiles exceeds the number of tiles required to be loaded on one side of the mahjong machine), in this embodiment, the length of the conveying channel 415 should be less than or equal to one fourth of the total length of the mahjong tiles, so as to ensure that the maximum capacity of the conveying channel 415 cannot exceed the number of the mahjong tiles on each side of the mahjong machine, and at the tile taking opening of the conveying channel 415, a second magnetic control sensor 46 connected with a main control board (the main control board can be arranged in an operation panel of a central lifting mechanism 10 of the mahjong machine) is arranged on the tile taking and conveying box cover 412, and the second magnetic control sensor 46 is used for detecting whether the mahjong tiles stay at the tile taking opening of the conveying channel 415 or counting the mahjong tiles entering the conveying channel 415, and the main control board is used for receiving output signals of the second magnetic control sensor 46 and controlling starting and stopping of a large-disc driving motor 61 according to the output signals. Meanwhile, a third magnetic control sensor 57 connected with the main control board is also installed on the second card baffle 55, the height of the third magnetic control sensor 57 is equal to that of the mahjong stacked on the uppermost part of the conveying belt 45, the third magnetic control sensor is used for detecting whether the mahjong stacked on the card bearing table 51 is completed or not and counting the number of the stacked mahjong piers, and the main control board is used for receiving output signals of the second magnetic control sensors 46 and controlling the large-disc driving motor 61 and the start and stop of the card pushing mechanism 8 according to the output signals.
Taking the length of the conveying channel 415 as the length of six mahjong tiles and 136 total mahjong tiles as an example, the working principle of the shuffling and taking stacking device of the full-automatic mahjong machine in the embodiment is described as follows:
when shuffling is needed, the large-disc driving motor 61 is started to drive the large shuffling disc 21 and the fluted disc 71 to rotate, the large shuffling disc 21 starts shuffling, meanwhile, the rotation of the fluted disc 71 is transmitted to the magnetic mahjong feeding wheel 42 through the first reversing transmission gear 74 and the second reversing transmission gear 75, and the magnetic mahjong feeding wheel 42 sucks mahjong tiles in the rotation process and brings the mahjong tiles into the conveying channel 415; under the conveying of the conveying belt 45, mahjong pieces fall onto the tile bearing table 51 from the tile outlet of the conveying channel 415, and under the action of the conveying belt 45 and the guide-falling rollers 56 on the surface of the tile bearing table 51, the mahjong pieces can stably fall onto the tile bearing table 51 and are overlapped; when the third magnetic control sensor 57 detects that the stacking of one tile pier is finished, the main control board pauses the large disc driving motor 61, the conveying belt 45 stops conveying the mahjong tiles, and after the tile pushing head 81 pushes the tile pier into the tile storage channel 82 and returns to the original position, the large disc driving motor 61 is started again, so that the tile pushing head 81 is prevented from returning to the original position because the mahjong tiles are continuously conveyed by the conveying belt 45 in the tile pushing process of the tile pushing head 81 (besides controlling the rotation frequency of the large disc driving motor 61, the tile blocking part 83 can be arranged on the tile pushing head 81, and the tile blocking part 83 is used for preventing the tile pushing head 81 from returning to the original position because the mahjong tiles are continuously conveyed by the conveying belt 45 in the tile pushing process of the tile pushing head 81).
When the third magnetic control sensor 57 detects that 14 piers are already stacked (because of stacking the piers simultaneously, all parties are stacked to complete 14 piers basically simultaneously), the main control board pauses the card pushing and feeding mechanism 8, and the 14 th pier temporarily exists in the card stacking space (used for blocking mahjong tiles on the conveying channel 415 from falling into the card storing channel; when the card blocking part 83 is arranged, the 14 th pier can be pushed into the card storing channel firstly, and the card blocking part 83 is abutted against a card outlet of the conveying channel 415 to prevent mahjong tiles from falling onto the card bearing platform 51); at this time, the large-disc driving motor 61 works normally, and the magnetic card feeding wheel 42 continuously takes cards until the conveying channel 415 is full of six mahjong pieces; as long as the other conveying channel 415 is not full, the big disc driving motor 61 continuously works, and the shuffling big disc 21 and the magnetic card feeding wheel 42 continuously rotate; if the mahjong pieces are absorbed by the magnetic tile loading wheels 42 at the positions of the conveying channels 415 where the mahjong pieces are fully stored, as the conveying belt 45 continuously runs, redundant mahjong pieces can fall into the large shuffling tray 21 again until the second magnetic control sensor 46 detects that all the mahjong pieces are fully stored in all the conveying channels 415, at the moment, the main control board pauses the large tray driving motor 61, the tile pushing mechanism 8 is started again, the rest six mahjong pieces are sequentially stacked in the tile stacking space according to the original operation, and the tile pushing mechanism 8 sequentially pushes the stacked tile piers into the tile storage rail 82 until all 17 tile piers are completely stacked.
