In the stacking and pushing mechanism, the card pushing head has an arc-shaped card pushing track from the card pushing starting point, so that the card storage track can extend from the card bearing table to the card lifting and bearing mechanism as soon as possible, the part of the card storage track extending forwards from the card bearing table is omitted, the occupied area of the mahjong machine is effectively reduced, the length of the card storage track is shortened, the time for feeding and lifting the cards is saved, and the card feeding operation and the card lifting operation are more efficient.

In the mahjong machine stacking and pushing mechanism for pushing the mahjong pieces in the arc shape, the mahjong piece storage track is in an arc shape, and the mahjong piece inlet end of the mahjong piece storage track and the mahjong piece bearing table are arranged in an included angle. Obviously, the included angle between the card inlet end of the card storage track and the card bearing table is an obtuse angle which is more than 90 degrees and less than 180 degrees, so that the card pier can smoothly slide into the card storage track from the card bearing table.

In the mahjong machine stacking and pushing mechanism for pushing the mahjong pieces in the arc shape, at the mahjong piece feeding end of the mahjong piece storage track, two side walls of the mahjong piece storage track are provided with guide cambered surfaces extending to one side of the mahjong piece bearing table. When the included angle between the card inlet end of the card storage track and the card bearing table is relatively smaller, the guide cambered surface is arranged to assist the card pier to slide into the card storage track from the card bearing table.

In the mahjong machine stacking and pushing mechanism for pushing the mahjong pieces in the arc shape, the top surface of the outer side wall of the mahjong piece storage track is provided with a sliding rail, and the sliding rail extends to a mahjong piece pushing starting point of the mahjong piece pushing head;

the tile pushing head comprises a tile pushing head body, wherein the tile pushing head body is provided with a first sliding rod which is in sliding fit with the sliding rail, and a tile pushing sliding block which extends into the tile storage track and is used for pushing the mahjong tile pier.

After the natural radian of the card storage track is utilized to set the sliding rail, the card pushing track of the card pushing head can be perfectly attached to the radian of the card storage track in the process of moving along the sliding rail, and the card pushing process is ensured to be carried out smoothly.

In the mahjong machine stacking and pushing mechanism for pushing the mahjong tiles in the arc shape, the tile bearing table is fixedly arranged at a tile outlet of the tile taking and conveying mechanism, a first conveying belt section for conveying the mahjong tiles is arranged in the tile taking and conveying mechanism, a second conveying belt section lower than the first conveying belt section is arranged on the surface of the tile bearing table, and the second conveying belt section and the first conveying belt section synchronously run;

the side of the carrying table is provided with a first blocking plate opposite to the tile outlet of the tile taking and conveying mechanism, the first blocking plate is rotatably provided with a guide roller opposite to the tile outlet of the tile taking and conveying mechanism, and the height of the guide roller is higher than the surface of the first conveying belt section and lower than the top surface of the mahjong tile on the first conveying belt section.

The invention sets the tile-bearing table at the lower part of the tile outlet of the tile-taking and conveying mechanism and sets the second conveying belt section on the surface, which is convenient for receiving the mahjong tiles falling from the tile outlet of the conveying channel of the tile-taking and conveying mechanism and stacking the mahjong tiles. Obviously, the height difference between the holding table and the conveying path may be set to be equivalent to the thickness of one mahjong tile (the thickness of one mahjong tile is equal to or greater than the thickness of two mahjong tiles and is smaller than the thickness of two mahjong tiles for stacking two mahjong tiles) or equivalent to the thickness of two mahjong tiles (the thickness of two mahjong tiles and is smaller than the thickness of three mahjong tiles for stacking three mahjong tiles).

The invention adopts the mahjong tile carrying table with fixed position, and not only the first conveying belt section is operated in the mahjong tile taking and conveying mechanism, but also the second conveying belt section is operated on the surface of the mahjong tile carrying table, and the synchronously operated second conveying belt section and the first conveying belt section are beneficial to relieving the inertial impact between mahjong tiles falling from the conveying channel and the surface of the mahjong tile carrying table, so that the mahjong tile is prevented from being planted. Meanwhile, the card stacking operation can be completed by driving the second conveying belt section to run without changing the position of the card bearing table, and the driving mode is simpler and more convenient.

In order to further simplify the driving mode, the first conveying belt section and the second conveying belt section belong to the same conveying belt, and the conveying belt stretches out from the card taking conveying mechanism and returns to the card taking conveying mechanism after bypassing the surface of the card bearing table. Therefore, the corresponding driving mechanism can drive the card taking and conveying operation in the card taking and conveying mechanism and the card stacking operation in the card stacking and pushing mechanism at the same time, and the driving mechanism is further saved.

When the speed of the conveyer belt is too high, the mahjong tiles are easily extruded on the first tile baffle plate in rows without falling, so that the invention arranges the guide-falling roller on the first tile baffle plate. 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.

The invention relates to a mahjong machine capable of pushing mahjong in an arc shape, which comprises a base, wherein at least three stacking and pushing mechanisms are arranged in the base, the stacking and pushing mechanisms are the stacking and pushing mechanisms of the mahjong machine capable of pushing mahjong in the arc shape, and a second driving mechanism for driving each stacking and pushing mechanism to work is further arranged on the base.

In the above mahjong machine with arc tile pushing, the second driving mechanism comprises a rotary table arranged above each stacking pushing mechanism and a rotary table driving motor for driving the rotary table to perform circumferential reciprocating motion, and a transmission structure for driving each tile pushing head to work is arranged on the bottom surface of the rotary table.

The invention utilizes the turntable driving motor to drive the turntable to rotate, and each transmission structure transmits the rotation of the turntable to the card pushing heads, thereby realizing the purpose of driving all the card pushing heads to work by utilizing one turntable driving motor and greatly saving the manufacturing cost and the operation cost.

Preferably, the turntable is in a circular ring shape, the transmission structure comprises a first annular folded edge fixed at the outer ring of the turntable, a second annular folded edge fixed at the inner ring of the turntable, and a second sliding rod fixed between the first annular folded edge and the second annular folded edge, and the card pushing head is in sliding fit with the second sliding rod.

Further preferably, for the same card pushing head, at least two second sliding rods are provided, and all the second sliding rods are arranged in parallel.

In the mahjong machine capable of pushing the mahjong in the arc shape, the mahjong pushing head is also provided with a card feeding position for pushing all the mahjong piers from the card feeding port to the card discharging port of the mahjong storage track. The card pushing head can push the card piers stacked on the card bearing table into the card storage track one by one, and can send all the card piers to the card lifting and bearing plate along the card storage track after all the card piers are stacked, so that the stacking pushing action and the card sending action are completed at one time, a driving mechanism is not required to be replaced, an additional card sending mechanism is not required to be arranged, and the consistency between the stacking pushing and the card sending operation is better.

In the mahjong machine for pushing the mahjong tiles in the arc shape, the output shaft of the turntable driving motor is provided with a second driving gear and a third driving gear which are coaxially arranged, and the outer diameter of the third driving gear is larger than that of the second driving gear; the turntable comprises a main disc and an auxiliary disc coaxially arranged with the main disc, and the outer diameter of the main disc is larger than that of the auxiliary disc;

the periphery of the main disc is provided with a card pushing tooth part, and the second driving gear is meshed with the card pushing tooth part to drive the card pushing head to switch between a card pushing starting point and a card pushing position; the periphery edge of the auxiliary disc is provided with a card feeding tooth part, and the third driving gear is meshed with the card feeding tooth part to drive the card pushing head to switch between a card pushing position and a card feeding position.

Since the outer diameter of the main disc is larger than that of the auxiliary disc, and the outer diameter of the second driving gear is smaller than that of the third driving gear; therefore, the rotating speed of the rotating disc when the second driving gear is meshed with the card pushing tooth part is slower than that of the rotating disc when the third driving gear is meshed with the card feeding tooth part, because the card pushing head 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 pusher 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 accelerated.

And the card pushing tooth part and the card feeding tooth part are arranged on part of the circumference of the turntable, and because the distance between the card pushing head at the card pushing starting point and the repeated card pushing position is smaller, the outer diameter of the main disk is set larger than that of the auxiliary disk, so that the card pushing tooth part is arranged on the circumference of the longer main disk, the card pushing tooth part and the second driving gear are ensured to have relatively longer meshing length, and the control precision of the turntable driving motor is improved.

Preferably, the auxiliary disc is arranged on the top surface of the main disc and is annular, a plurality of supporting bars protruding out of the top surface of the main disc are formed on the main disc, and all the supporting bars extend along the radial direction of the top surface of the main disc and are abutted against the inner peripheral edge of the annular auxiliary disc.

In the above-mentioned arc tile pushing mahjong machine, a third magnetic control sensor connected with a main control board is arranged at the tile pushing start point of the tile pushing head, the third magnetic control sensor is used for detecting whether the stacking of the mahjong tiles on the tile bearing table is completed and 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 and controlling the start and stop of the turntable driving motor according to the output signal;

the outer periphery of the main disk is provided with a fourth magnetic control sensor for monitoring the rotation angle of the main disk, the fourth magnetic control sensor is connected with a main control board, and the main control board is used for receiving an output signal of the fourth magnetic control sensor and controlling the start, stop and steering of a turntable driving motor according to the output signal.

The third magnetic control sensor detects whether the mahjong pieces are overlapped or not, so that the mahjong piece pushing head is convenient to control to switch between the mahjong piece pushing initial position and the repeated mahjong piece pushing position, and the number of the overlapped mahjong pieces is counted to control the mahjong piece pushing head to switch from the repeated mahjong piece pushing position to the mahjong piece feeding position. And the fourth magnetic control sensor is used for monitoring the rotation angle of the turntable, and after the turntable rotates by a preset angle, the fourth magnetic control sensor sends a signal to the main control board, and the main control board pauses the turntable driving motor and changes the steering direction of the turntable driving motor.

Compared with the prior art, the invention has the beneficial effects that:

in the stacking and pushing mechanism, the card pushing head has an arc-shaped card pushing track from the card pushing starting point, so that the card storage track can extend from the card bearing table to the card lifting and bearing mechanism as soon as possible, the part of the card storage track extending forwards from the card bearing table is omitted, the occupied area of the mahjong machine is effectively reduced, the length of the card storage track is shortened, the time for feeding and lifting the cards is saved, and the card feeding operation and the card lifting operation are more efficient.

As shown in fig. 7 and 8, in conjunction with fig. 6, a stacking mechanism 5 is provided at the card outlet of the feed path 415. The stacking mechanism 5 comprises a card bearing table 51 formed by a part of the top wall of the card taking and conveying box rack 411, and a lower cavity 414 in the card taking and conveying box 41 extends to the lower part of the card bearing table 51; the card table 51 is located at a lower level than the conveying path 415, and a reversing wheel 52 and a second conveying wheel 53 are respectively arranged on opposite sides of the card table 51, wherein the reversing wheel 52 is located right below the first conveying wheel 43. The conveyer belt 45 extends out from the card outlet of the conveyer channel 415 and descends, and after being diverted by the reversing wheel 52, the conveyer belt firstly moves to the surface of the card bearing table 51, then bypasses the second conveyer wheel 53 and returns to the lower cavity 414; the common conveying belt 45 of the tray table 413 and the card bearing table 51 is realized, and the card feeding and stacking are driven by the same large disc driving motor 61, so that the consistency of the card feeding action and the card stacking action is better.

Obviously, the height difference between the holding table 51 and the delivery path 415 should be equivalent to the thickness of one mahjong tile (for stacking two mahjong tiles) or to the thickness of two mahjong tiles (for stacking three mahjong tiles). The conveyer 45 slides from the surface of the tile-supporting table 51 to be beneficial to relieving the inertial impact between the mahjong tiles falling from the conveying channel 415 and the surface of the tile-supporting table 51, and avoiding tile placement.

However, when the height difference between the deck 51 and the delivery path 415 is large, the falling mahjong pieces may possibly turn; and when the feed speed is too high, the continuously fed mahjong tiles may become crowded and abut against the first tile stop 54. Thus, in this embodiment, the first card guard 54 is rotatably mounted with the guide roller 56 opposite the feed path 415, and the guide roller 56 is located at a height above the surface of the feed belt 45 and below the top surface of the mahjong tiles on the feed belt 45.

Wherein, can install the paster on storing up the inside wall of tablet track 57 in order to adjust the size of the interior track space of tablet track 57 to the mahjong pieces of adaptation equidimension. As shown in fig. 6, the top surface of the outer side wall of the card storing rail 57 is provided with a sliding rail 571, the sliding rail 571 extends above the second card baffle 55, and the card pushing head 58 is slidably mounted in the sliding rail 571; a second driving mechanism 12 for driving each card pushing head 58 to move along the card storing track 57 is arranged on the top surface of the integrated part 102.

The card pusher 58 of this embodiment includes a card pusher body 581, the card pusher body 581 has a first slide rod 582 slidably engaged with a slide rail 571 and a card pusher block 583 extending into the card storage rail 57, and the card pusher block 583 has a card blocking portion 584 on a side facing the conveying path 415. The start point of the tile pushing block 583 is close to the second tile blocking plate 55, and at the same time, the tile pushing block 583 has a repeated tile pushing position (the tile blocking portion 584 does not leave the tile stacking space during tile pushing) for pushing the tile piers on the tile holding table 51 into the tile storage rail 57 one by one while preventing the tile from falling onto the tile holding table 51 from the conveying channel 415, and a tile feeding position for pushing all the tile piers in the tile storage rail 57 onto the tile lifting tile holding plate 61.

It should be noted that, the blocking portion 584 is not necessary in the present invention, and in the case where the conveyer 45 is continuously running (the stacking operation is not completed, and the large-disc drive motor 111 is continuously rotated), the blocking portion 584 is provided to prevent the conveyer 45 from continuously conveying the mahjong pieces into the stacking space when the pusher 58 is away from the stacking space, so that the pusher 58 cannot return to the pusher starting point; 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 58 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 58 finishes pushing tiles and returns to the tile pushing start point, the large-disc driving motor 111 is started again.

As shown in fig. 4 and 5, 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 corresponding to the card pushing heads 58 one by one are arranged on the four directions of the bottom surface of the main disc 121a, and the card pushing head body 581 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. 3, 4 and 5, 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 583 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 583 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 58 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; the card pusher 58 pushes all the card piers together when feeding cards, and the speed is slightly increased, so that the phenomenon that the card piers turn over can not occur, and the card feeding speed can be increased.

As shown in fig. 4 and 5, 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 mahjong pieces with the same quantity are conveyed by each mahjong piece taking and conveying mechanism 4 and avoid that each mahjong piece taking and conveying mechanism 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 pieces, and the maximum capacity of the conveying channel 415 cannot exceed the quantity of the mahjong pieces of each party 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 59 connected with the main control board is also installed on the second card baffle 55, the height of the third magnetic control sensor 59 is equal to the height of the mahjong tiles stacked on the uppermost part of the conveyer 45, and the third magnetic control sensor is used for detecting whether the mahjong tiles on the card bearing table 51 are stacked, counting the number of the stacked mahjong piers, and the main control board is used for receiving the output signal of the third magnetic control sensor 59 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 card baffle 584 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 59 detects that 14 mahjong tiles are stacked, the main control board pauses the turntable driving motor 122, and meanwhile the blocking part 584 of the tile pushing slider 583 abuts 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 absorbed by the magnetic tile feeding wheels 42 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 all the conveying channels 415, at the moment, the main control board pauses the large tray driving motor 111, the turntable driving motor 122 is started, at the moment, the second driving gear 123 is meshed with the tile pushing tooth parts 121d, and the rest six mahjong tiles are stacked and pushed. After all 17 piers are stacked and pushed into the card storing rail 57, the turntable driving motor 122 continues to operate, and at this time, the third driving gear 124 is meshed with the card feeding tooth portion 121e, so that all the piers are pushed to the card lifting and carrying mechanism 7 located in the card storing rail 57.

The working principle of the mahjong machine for pushing the mahjong in the arc shape of the embodiment is as follows:

when shuffling is needed, the large-disc driving motor 61 is started and rotates positively to drive the shuffling large disc 21 and the fluted disc 81 to rotate, the rotation of the fluted disc 81 is transmitted to the magnetic card feeding wheel 42 through the first reversing transmission gear 84 and the second reversing transmission gear 85, and mahjong tiles are sucked and brought into the conveying channel 415 in the rotating process of the magnetic card feeding wheel 42; at this time, the blocking portion 584 of the tile pushing head 58 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 58 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 smoothly fall onto the tile bearing table 51 under the action of the conveying belt 45 and the guide roller 56 on the surface of the tile bearing table 51, and are stacked, and each time stacking of one tile pier is completed, the tile pushing head 58 moves to the repeated tile pushing position from the tile pushing starting position, and the tile piers are pushed into the tile storage track 57 one by one; when the third magnetic control sensor 59 detects that the first block of tiles is already stacked (because of stacking tiles simultaneously, each side is stacked substantially simultaneously to complete the first block of tiles), the main control board pauses the turntable driving motor 122, and simultaneously the blocking portion 584 of the tile pushing slider 583 abuts 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 61 works normally, and the magnetic card feeding wheel 42 continuously takes cards until the conveying channel 415 is full of mahjong tiles; 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 feeding 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 the conveying channels 415, at the moment, the main control board pauses the large tray driving motor 61, starts the turntable driving motor 122, the second driving gear 123 is meshed with the tile pushing tooth parts 121d, and the rest six mahjong pieces are stacked and pushed until all 17 tile piers are stacked and pushed into the tile storage track 57.

Under the condition that no blocking part 584 is arranged, when mahjong tiles are conveyed in the conveying channel 415, whenever the third magnetic control sensor 59 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 main control board starts the turntable driving motor 122, and the tile pushing head 58 pushes the four tile piers into the tile storage track 57 at the same time until the first tile pier is overlapped (the third magnetic control sensor 59 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 415, 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 at the moment, the third driving gear 124 is meshed with the tile feeding tooth part 121e to drive the tile pushing head 58 to push the second batch of stacked tile piers into the tile storage track 131, and 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 slide block 583 or the tile blocking portion 584 in the tile fetching and conveying process of the tile fetching and conveying mechanism 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 58 pushes the mahjong cards in the card storage rail 57 towards 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.
