the distance between the lower fin plate and the fixed end of the card lifting and bearing plate is smaller than the distance between the lower fin plate and the free end of the card lifting and bearing plate.

The additionally arranged lower fin plate is used as the extension of the second rocker arm, so that the card lifting and carrying plate can still turn over a larger angle on the premise of adopting the second rocker arm with a smaller action range, thereby improving the transmission efficiency. The lower fin plate is arranged closer to the fixed end of the card lifting and supporting plate, and the second rocker arm with a smaller action range is adopted to drive the card lifting and supporting plate to turn over by a larger angle. The distance between the second rocker and the two end faces of the lower fin plate is set to be equal to or larger than the action radius of the second rocker, so that the second rocker is always abutted against the bottom face of the lower fin plate no matter how the second rocker acts, the turnover of the card lifting and bearing plate is stable, and the card lifting and bearing plate cannot be rapidly lifted.

The card pushing head 132 of the present embodiment includes a card pushing head body 132a, the card pushing head body 132a has a first sliding rod 132b slidably engaged with the sliding groove 131a and a card pushing slider 132c extending into the card storing track 131, and the card pushing slider 132c has a card blocking portion 132d facing one side of the conveying channel 415. The card pushing start point of the card pushing slider 132c is close to the second card blocking plate 55, and at the same time, the card pushing slider 132c has a repeated card pushing position (the card blocking part 132d does not leave the card stacking space during the card pushing process) for pushing the card piers on the card holding table 51 into the card storage rail 131 one by one while preventing the mahjong pieces from falling onto the card holding table 51 from the conveying channel 415, and a card feeding position for pushing all the card piers in the card storage rail 131 onto the card lifting card holding plate 61.

It should be noted that, the blocking portion 132d is not necessary in the present invention, and in the case where the conveyer 45 is continuously running (the stacking operation is not finished, and the large-disc driving motor 111 is continuously rotating), the blocking portion 132d is provided to prevent the returning of the pusher head 132 to the pusher start point due to the fact that the conveyer 45 continuously conveys the mahjong pieces into the stacking space when the pusher head 132 leaves the stacking space; of course, the rotation frequency of the large-disc driving motor 111 can also be controlled to prevent mahjong tiles from falling into the stacking space when the tile pushing head 132 leaves the stacking space, for example, when two mahjong tiles are conveyed into the stacking space, the large-disc driving motor 111 is stopped, and after the tile pushing head 132 pushes tiles and returns to the tile pushing initial point, the large-disc driving motor 111 is started again.

As shown in fig. 3 and 4, the output shaft of the turntable driving motor 122 of the present embodiment is mounted with a second driving gear 123 and a third driving gear 124 coaxially provided, and the turntable 121 includes a main disk 121a and a sub disk 121b coaxially provided with the main disk 121 a.

Wherein the main disc 121a is in a circular ring shape, the transmission structure 125 comprises a first annular folded edge 125a at the outer ring of the bottom surface of the main disc 121a, a second annular folded edge 125b at the inner ring of the bottom surface of the main disc 121a, and a second sliding rod 125c fixedly installed between the first annular folded edge 125a and the second annular folded edge 125 b; the second slide bars 125c are arranged on the four directions of the bottom surface of the main disc 121a and are in one-to-one correspondence with the card pushing heads 132, and the card pushing head body 132a is slidably arranged on the second slide bars 125c; at least two second slide bars 125c are provided on each side of the main disk 121a, and all the second slide bars 125c on the same side are disposed in parallel. The auxiliary disc 121b is disposed on the top surface of the main disc 121a and has a ring shape, and a plurality of stays 121c protruding from the top surface of the main disc 121a are formed on the main disc 121a, and all the stays 121c extend radially along the top surface of the main disc 121a and abut against the inner peripheral edge of the ring-shaped auxiliary disc 121b.

As can be seen from fig. 2, 3 and 4, in this embodiment, the periphery of the main disk 121a is provided with a card pushing tooth 121d, and the second driving gear 123 is meshed with the card pushing tooth 121d to drive the card pushing slider 132c to switch between a card pushing start position and a repeated card pushing position; the peripheral edge of the auxiliary disc 121b is provided with a card feeding tooth portion 121e, and the third driving gear 124 is meshed with the card feeding tooth portion 121e to drive the card pushing slider 132c to switch between the repeated card pushing position and the card feeding position, the peripheral edge of the main disc 121a is provided with a fourth magnetic control sensor 126 for monitoring the rotation angle of the main disc 121a, the fourth magnetic control sensor 126 is connected with a main control board, and the main control board is used for receiving the output signal of the fourth magnetic control sensor 126 and controlling the start, stop and steering of the turntable driving motor 122 according to the output signal.

Since the outer diameter of the main disc 121a is larger than that of the sub disc 121b, the outer diameter of the second driving gear 123 is smaller than that of the third driving gear 124; therefore, the rotation speed of the turntable 121 when the second driving gear 123 is meshed with the card pushing tooth portion 121d is slower than that of the turntable 121 when the third driving gear 124 is meshed with the card feeding tooth portion 121e, because the card pushing head 132 only pushes one card pier at a time when pushing cards, and if the card pushing speed is too fast, the card pier can easily tip over; when the card is sent, the card pushing head 132 pushes all the card piers together, the speed is slightly increased, the phenomenon that the card piers turn over can not occur, and the card sending speed can be increased.

As shown in fig. 3 and 4, the rotation mounting manner between the turntable 121 and the integrated part 102 is: at least two pressing strips 127 (four pressing strips 127 are uniformly distributed at four positions of the main disc 121a in the embodiment) are fixed on the top surface of the integral forming part 102 through threads, a hollow shaft 128 is rotatably arranged on bolts (at least two bolts are arranged on one pressing strip 127) for fixing the pressing strips 127 on the integral forming part 102, a second roller 129 (also can be a bearing) is arranged on the hollow shaft 128, an annular groove 125d for accommodating each second roller 129 is formed on the second annular flange 125b, and when the turntable driving motor 122 drives the turntable 121 to rotate, the second roller 129 rolls along the annular groove 125 d.

In order to ensure that the same number of mahjong tiles are conveyed by each tile-fetching and conveying unit 4 and avoid that each tile-fetching and conveying unit 4 carries out repeated tile-returning operation, the length of the conveying channel 415 is set to be less than or equal to one fourth of the total length of the mahjong tiles, and the maximum capacity of the conveying channel 415 cannot exceed the number of the mahjong tiles on each side of the mahjong machine; meanwhile, at the tile taking port of the conveying channel 415, a second magnetic control sensor 46 connected with a main control board is arranged on the tile taking conveying box cover 412, the second magnetic control sensor 46 is used for detecting whether magnetic mahjong tiles remain at the tile taking port of the conveying channel 415 or counting mahjong tiles entering the conveying channel 415, and the main control board is used for receiving an output signal of the second magnetic control sensor 46 and controlling the start and stop of the large-disc driving motor 111 according to the output signal. And, a third magnetic control sensor 57 connected with the main control board is also installed on the second tile blocking board 55, the height of the third magnetic control sensor 57 is equal to the height of the mahjong tiles stacked on the uppermost part of the conveying belt 45, and the third magnetic control sensor is used for detecting whether the mahjong tiles on the tile bearing table 51 are stacked, counting the number of the stacked mahjong tiles, and the main control board is used for receiving the output signal of the third magnetic control sensor 57 and controlling the turntable driving motor 122 (or the turntable driving motor 122 and the large-disc driving motor 111) according to the output signal, and on the premise that the tile blocking part 132d is not provided, the turntable driving motor 122 and the large-disc driving motor 111 are required to be controlled to start and stop simultaneously.

Taking the length of the conveying channel 415 as the length of six mahjong tiles and 136 total mahjong tiles as an example, when one third magnetic control sensor 57 detects that 14 mahjong tiles are stacked, the main control board pauses the turntable driving motor 122, and meanwhile the blocking part 132d of the tile pushing sliding block 132c is abutted against the tile outlet of the conveying channel 415 to prevent the mahjong tiles from falling to the tile bearing table 51; at this time, the large-disc driving motor 111 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 111 continuously works, and the shuffling big disc 21 and the magnetic card feeding wheel 42 continuously rotate; if the mahjong tiles are adsorbed by the magnetic tile loading wheels at the positions of the conveying channels 415 where the mahjong tiles are fully stored, as the conveying belt 45 continuously runs, redundant mahjong tiles can fall into the large shuffling tray 21 again until the second magnetic control sensor 46 detects that all the mahjong tiles are fully stored in the conveying channels 415, at the moment, the main control board pauses the large tray driving motor 111, and starts the turntable driving motor 122 to engage the second driving gear 123 with the tile pushing tooth parts 121d at the moment, so that the rest six mahjong tiles are stacked and pushed. After all 17 piers are stacked and pushed into the card storing rail 131, the turntable driving motor 122 continues to operate, and at this time, the third driving gear 124 is meshed with the card feeding tooth 121e, so that all piers are pushed to the card feeding end of the card storing rail 131.

after the game on the panel is finished, the user operates the operation panel, the main control board starts the large-disc driving motor 111, the large-disc driving motor 111 reversely rotates, the central lifting mechanism 14 is driven by the first unidirectional transmission mechanism 15 to drive the operation panel to ascend, and at the moment, the user enters mahjong tiles on the panel into the shuffling large disc 21 through the tile return holes;

after the card returning is completed, the user operates the operation panel, the main control panel starts the large-disc driving motor 111 again, and the large-disc driving motor 111 continues to reversely rotate to drive the operation panel to return to the card returning hole;

while the lifting rod 32 is lifted, the first driving gear 112 drives the shuffling large disc 21 and the fluted disc 81 to reversely rotate, the rotating fluted disc 81 is driven by the first reversing transmission gear 84 and the second reversing transmission gear 85 to reversely rotate the magnetic card feeding wheel 42 along with the first driven gear 82, and the second rocker 63 reversely rotates along with the second driven gear 91, at the moment, the conveying belt 45 reversely runs from the card outlet to the card taking outlet of the conveying channel 415, no cards are taken, and the free end of the card lifting and carrying plate 61 descends; the main control board starts the large disc driving motor 111 to enable the third driving gear 124 to be meshed with the mahjong feeding tooth part 121e, all mahjong piers reserved in the mahjong storage track 131 are pushed onto the mahjong lifting and carrying board 61, the second rocker 63 continues to rotate to drive the free end of the mahjong lifting and carrying board 61 to lift, and mahjong tiles are fed onto the panel; when the operation panel returns to the card returning hole, the card lifting and carrying plate 61 completes the card lifting action;

The main control board immediately starts the big disc driving motor 111, at the moment, the big disc driving motor 111 rotates forward, the first driving gear 112 drives the big shuffling disc 21 and the fluted disc 81 to rotate forward (at the moment, the first unidirectional transmission mechanism 15 does not transmit), the big shuffling disc 21 breaks up the mahjong tiles, and meanwhile, the mahjong tiles slide down to the periphery of the big shuffling disc 21 along the conical surface 211; the fluted disc 81 drives the conveyer belt 45 to move from the card taking port of the conveyer passage 415 to the card outlet direction, and the magnetic card feeding wheel 42 magnetically sucks the mahjong tiles scattered on the periphery of the large shuffling tray 21 onto the conveyer belt 45 and enters the conveyer passage 415;

at this time, the blocking part 132d of the tile pushing head 132 abuts against the tile outlet of the conveying channel 415, when the conveying channel 415 is full of tiles, the turntable driving motor 122 is started, the tile pushing head 132 moves to the tile pushing starting position, the tiles fall onto the tile bearing table 51 from the tile outlet of the conveying channel 415 under the conveying of the conveying belt 45, the tiles can stably fall onto the tile bearing table 51 under the action of the conveying belt 45 and the guide and drop rollers 56 on the surface of the tile bearing table 51, the tiles are stacked on the tile bearing table 51, when the stacking of the first tile pier is completed (monitored by the third magnetic control sensor 57), the main control board starts the turntable driving motor 122, the second driving gear 123 is meshed with the tile pushing tooth part 121d, the turntable 121 is driven to rotate, the tile pushing head 132 is driven to push tiles into the tile storage track 131 (the fourth magnetic control sensor 126 monitors the rotation angle of the main disc 121a, and returns to the original path) until all the first tile piers are pushed, the turntable driving motor 122 stops, the tile pushing head 132 stops on the tile bearing table 51, the tile receiving table is stopped, the tile receiving channel is completely moved up again, and the tile receiving channel is completely moved up by the second magnetic control sensor 122, and the tile receiving channel is completely stacked in the conveying channel is started (when the tile receiving channel is completely moved up, and the tile receiving channel is completely and completely moved by the tile receiving the tile, and is completely and completely stored by the tile receiving the tile, and the tile receiving motor is completely, and the tile is completely suspended, and the tile is completely and finally transported by the tile.

Under the condition that the blocking part 132d is not arranged, when mahjong tiles are conveyed in the conveying channel 415, whenever the third magnetic control sensor 57 detects that one tile pier is overlapped in the tile overlapping space, the main control board pauses the large-disc driving motor 111, when one tile pier is overlapped in the four tile overlapping spaces, the turntable main control board starts the turntable driving motor 122, and the tile pushing head 132 pushes four tile piers into the tile storage rail 131 at the same time until the first tile pier is overlapped (the third magnetic control sensor 57 counts the tile piers); the last tile pier of the first batch of tile piers is temporarily left in the tile stacking space and used for blocking the tile outlet of the conveying channel, at the moment, the large disc driving motor 111 continuously rotates, and the conveying belt 45 continuously runs until the conveying channel 415 is full of mahjong tiles; after all the conveying channels 415 are full of mahjong tiles (monitored by the second magnetic control sensor 46), the main control board starts the turntable driving motor 122 again, and pushes the second stacked tile piers into the tile storage track 131 to wait for next tile lifting.

The working principle is suitable for the situation that the length of the conveying channel 415 is smaller than one fourth of the total length of the mahjong tiles, and for the situation that the length of the conveying channel 415 is equal to one fourth of the total length of the mahjong tiles, the mahjong tiles are required to be stacked after all the conveying channels 415 are fully stored in advance, so that the tile outlet of the conveying channel 415 is blocked by the tile pushing sliding block 132c or the tile blocking part 132d in the process of shuffling and conveying the tiles by the tile fetching and conveying unit 4; after each conveying channel 415 is full of mahjong tiles, the main control board starts the turntable driving motor 122, and the mahjong tiles are stacked in the same tile stacking mode.

When a card is required to be lifted, the turntable driving motor 122 is started, the third driving gear 124 is meshed with the card feeding tooth part 121e, the card pushing head 132 pushes the mahjong cards in the card storage rail 131 to the direction of the card lifting and carrying plate 61, at the moment, the large-disc driving motor 111 is reversed, the reversed shuffling large disc 21 and the fluted disc 81 are driven to the magnetic card feeding wheel 42 through the first reversing driving gear 84 and the second reversing driving gear 85, so that the magnetic card feeding wheel 42 reversely rotates along with the first driven gear 82, the second rocker arm 63 reversely rotates along with the second driven gear 91, and the free end of the card lifting and carrying plate 61 is lowered; after the mahjong tiles are pushed onto the mahjong tile lifting and supporting plate 61 by the mahjong tile sending mechanism, the second rocker arm 63 continues to rotate to drive the free end of the mahjong tile lifting and supporting plate 61 to lift, and the mahjong tiles are sent onto the panel.
