The four card outlets are arranged in a windmill shape, and each card outlet is inclined at an angle with the bottom edge of the table, namely the windmill shape is inclined, so that the table top can be made smaller, and the inclination of the card strips also accords with the habit of a player; secondly, when the card is played, the whole card pier is not built and then lifted up to the tabletop, but pushed up to the tabletop along the slope, so that the space inside the machine can be reduced, and the size of the whole machine can be reduced. However, in the card discharging device, the whole card storage groove is arranged in a slope shape, the resistance of the card feeding process is large, the load of a steel wire rope motor is large, steel wires are easy to shake and break, the card feeding process is not stable enough, the service life of the steel wire rope is low, the arrangement of the card storage groove, the stacking and pushing machine head and the conveying device (a mechanism for picking up mahjong cards from a large tray and conveying the mahjong cards to the stacking and pushing machine head) is unreasonable, the conventional square independent stacking and pushing machine head is difficult to push mahjong cards to a card inlet of a card storage groove track, and the height of a host machine is high.

The patent document with the publication number of CN201783185U discloses a chain-driven slope tile discharging device for a full-automatic mahjong machine, which is provided with four lifting tile lifting plates hinged with a tabletop, one end of each lifting tile lifting plate is a tile inlet, the outer side of each lifting tile plate is provided with a conveying belt, one side of the conveying belt is provided with a stacking mechanism, the outer sides of the four conveying belts are provided with arc-shaped tile storage grooves, an annular closed chain is arranged below each groove, and vertical chain rods are arranged on each chain at intervals of a set distance.

Patent document with publication number CN102133480A discloses a full-automatic mahjong machine, which comprises a mahjong feeding system, a mahjong lifting system and a mahjong shuffling large tray, wherein the mahjong feeding system comprises four mahjong pushing devices, four mahjong feeding tracks and a chain transmission device. The height of the tile feeding system is basically level with that of the tile lifting system, so that although the height of the host is reduced, the arrangement position of the tile lifting system can cause interference to the large-disc shuffling and the tile feeding system for sucking the mahjong tiles, and the tile lifting system is only suitable for small mahjong tiles. In addition, the arrangement of the tile outlet of the tile feeding system and the tile inlet of the tile feeding track is unreasonable, the tile pushing device does not have the tile stacking function, and the mahjong tiles are automatically stacked on the tile bearing table board, so that the mahjong tiles are not stacked neatly and are easy to move and misplaced, and the mahjong tiles cannot enter the tile feeding track, and generate faults such as confusion in the tile feeding track. In addition, after the horizontal card feeding rail is adopted, mahjong tiles close to the card outlet of the card feeding rail are very easy to fall from the card outlet back to the shuffling large tray; the adoption of the chain and the flag wheel structure has high noise.

The automatic mahjong machine disclosed in patent documents with publication numbers of CN201906453U and CN201949619U, wherein a mahjong storage plate in a mahjong storage track of the mahjong machine is obliquely arranged, one end of the mahjong storage plate is in butt joint with a mahjong bearing plate, a mahjong stacking pushing head pushes mahjong on the mahjong bearing plate onto the mahjong storage plate, and after mahjong pieces on the mahjong storage plate are arranged in a row, a mahjong feeding pushing head pushes the whole row of mahjong pieces to an upper mahjong piece assembly; because the pile card is pushed away and is provided with the groove of dodging, upward be provided with the push rod on the card is pushed away and is pushed away the head to make two push away and to push away and set up alternately from top to bottom, both can avoid each other through dodging the groove when pushing away the tablet respectively like this. However, since the card storage rail is passed over the conveying section of the card feeding device, the height of the main body of the mahjong machine is high (the height of the card feeding device and the height of the card feeding device are overlapped), and in addition, the L-shaped card storage rail is short, so that the universality is poor.

The automatic mahjong machine disclosed in patent documents with publication numbers CN103861280a and CN104645608A also has the problems of higher height of the main machine (height superposition of the card feeding device and the card feeding device), shorter L-shaped card storage track, and the like. In addition, after the horizontal card feeding rail is adopted, mahjong tiles close to the card outlet of the card feeding rail are very easy to fall from the card outlet back to the shuffling large tray; the steel wire rope is adopted to drive the card feeding pushing head to move, and the steel wire rope and the side wall of the track are severely rubbed, so that the service life is low.

The patent document with the publication number of CN204699375U discloses an automatic mahjong machine with an improved structure, which comprises a mahjong feeding system, a mahjong lifting system and a mahjong shuffling large tray, wherein the mahjong feeding system comprises four mahjong feeding mechanisms, each mahjong feeding mechanism comprises a transmission frame and a conveying belt fixed on the transmission frame, the four mahjong feeding mechanisms are sequentially connected to form a rectangular structure, and the mahjong shuffling large tray is arranged in the four mahjong feeding mechanisms. The mahjong tile feeding track adopts the whole large arc-shaped structure, so that the friction force between mahjong tiles and the mahjong tile feeding track is reduced, and the faster mahjong tile feeding speed and smaller mahjong tile feeding noise are ensured. And, the arrangement positions of the card feeding system and the card sending system are designed in an overlapping mode, so that the height of the host is reduced. However, because the mahjong tile feeding device adopts straight lines to feed and discharge mahjong tiles, the tile outlet of the mahjong tile feeding device and the tile inlet of the tile feeding track still cannot be reasonably arranged, the tile pushing resistance of the stacking pushing device is large and the tiles are easy to clamp, and the large arc-shaped tile feeding track causes the increase of the table surface size of the mahjong machine.

Patent document with publication number CN105413161a discloses a tile feeding driving mechanism, a tile feeding assembly and a mahjong machine, the tile feeding driving mechanism of the mahjong machine comprises a tile feeding bracket, a tile storage groove, a tile feeding guide rail, a tile feeding pushing head and a steel wire rope, rolling elements are arranged at positions, close to the tile feeding guide rail and/or the tile storage groove, of the steel wire rope, the rolling elements are rotatably arranged on the tile feeding guide rail or the tile feeding bracket, and the part of the steel wire rope in the tile storage groove is in rolling contact with a plurality of rolling elements and keeps a gap with the side wall of the tile feeding guide rail and/or the tile storage groove. According to the scheme, rolling friction of the steel wire rope is used for replacing sliding friction of the steel wire rope in the prior art, so that friction resistance of operation of the steel wire rope is greatly reduced, and the influence on the service life and operation stability of the steel wire rope due to sliding friction contact between the part of the steel wire rope in the card storage groove and the arc-shaped curved side wall of the card loading guide rail and/or the card storage groove is avoided.

In the prior art, most of the card feeding driving mechanisms adopt a steel wire rope driving structure or a chain driving structure. Because the length of the card storage groove is longer and the arc bending exists, the card feeding push head is in sliding friction contact with the card feeding guide rail, so that in actual use, the problems of large card feeding push head resistance, limited card feeding quantity, large motor load and the like exist. Therefore, the patent document with the publication number of CN106075897A discloses a mahjong machine, a mahjong feeding assembly and a mahjong feeding driving mechanism thereof, a way of pushing the mahjong by adopting the connection force of two mahjong feeding push rods is adopted, a reversing groove is arranged to realize the connection and pushing of two mahjong feeding push heads, and the mahjong in a mahjong storage groove is pushed by adopting the connection force of the two mahjong feeding push heads, so that a guide rail for guiding the movement of the mahjong feeding push heads is not required to be arranged, and the defects of large resistance between the mahjong feeding push heads and the guide rail, large working noise of a chain and the like in the prior art are completely avoided.

However, in the prior art, whether a steel wire rope driving structure, a chain driving structure or two card feeding push rod power pushing structures are adopted, the two card feeding push rod power pushing structures are directly connected with a driving motor or are connected through a plurality of gears and other simple transmission modes. In addition, in the card lifting assembly or the slope card discharging device disclosed in patent documents with publication numbers CN105363196A, CN105413160A, CN105413165A, CN105521601A, CN106075895A, CN106075897A, CN105536243a and CN105709413a, the card lifting structure is also directly connected with the driving motor. The slope tile-discharging device on one side needs two motors, namely a tile-feeding motor and a tile-lifting motor, so that the manufacturing cost is high, and the tile-lifting motor is directly arranged above the central turntable of the mahjong machine, so that the height of the main machine of the mahjong machine is increased, the thinning of the mahjong machine is limited, and the general motor with larger volume and more reasonable price is not suitable to be adopted, so that the manufacturing cost is further increased.

The matching working process of the card lifting assembly and the card lifting assembly is as follows:

when sufficient mahjong tiles are stored in the tile storage tank in the tile feeding assembly, the tile lifting support plate 601 descends. At this time, the driving motor 701 drives the driving wheel 703 to rotate, the rotation of the driving wheel 703 rotates the cam groove 7032 thereof, the cam groove 7032 rotates to drive the roller a607 (path bearing) fixed on the swing rod 606 to swing down along the cam track, and the card lifting support plate 601 falls to the card receiving position through the transmission of the transmission mechanism, as shown in fig. 9 and 10. Meanwhile, the bevel gear part of the driving wheel 703 is matched with the bevel gear part of the driven wheel 704 to drive the driven wheel 704 to move, but the baffle 708 prevents the transmission sleeve 705 from being combined with the driven wheel 704 to drive so as to separate the transmission shaft 706 from the driven wheel 704 and not transmit torque, so that the transmission shaft 706 does not rotate in the process, and the third gear 517 of the transmission shaft 706 does not drive the card feeding driving mechanism to move, and the card feeding pushing head does not push cards.

After the card lifting supporting plate 601 falls to the lowest point, the limiting position (clutch) of the clutch positioning block 7031 of the driving wheel 703 and the torsion spring baffle 708 is pulled from the low position to the high position, so that the torsion spring baffle 708 is partially jacked up. At this time, under the tension inertia of the torsion spring 711, the driving sleeve 705 rotates rapidly until the torsion spring is re-tensioned on the two tensioning sleeves (the speed is fast and the time is short), so that the driven wheel 704 and the transmission shaft 706 resume the linkage state again, and the card feeding driving mechanism starts to move. Meanwhile, the roller a607 is in a low position in the cam groove 7032 of the driving wheel 703, the swing rod 606 is not moved, and the card lifting support plate 601 is kept still.

The card feeding assembly starts card feeding: the first card feeding push rod 503 rotates towards the card inlet of the card storage groove 502, the first card feeding push head 5033 pushes the mahjong cards in the card storage groove to feed the cards, the second card feeding push rod 507 rotates towards the reversing groove 509, the card feeding swing rod 513 is in a contracted state, and the second card feeding push head 5131 moves along the retracting groove 511; the first card-feeding pusher 5033 moves to the vicinity of the reversing groove 509, the second card-feeding pusher 5131 enters the reversing groove 509, and the third link 510 (or the fourth link 512) touches the unfolding positioning member so that the card-feeding swing rod 513 rotates outwards to the unfolded state; the first tile-feeding pusher 5033 pushes the last pier of mahjong tile in the tile storage groove through the reversing groove 509, the second tile-feeding pusher 5131 enters the tile storage groove 502 from the reversing groove 509 and is connected with the first tile-feeding pusher 5033 in a receiving manner to start pushing the mahjong tile to feed the mahjong tile, and the first tile-feeding pusher 5033 moves outside a tile inlet of the tile storage groove 502; after the second tile-feeding push head 5131 pushes the mahjong tiles out of the tile storage groove and pushes the tile-lifting support plate, the third connecting rod 510 (or the fourth connecting rod 512) touches the shrinkage positioning piece so that the tile-feeding swing rod 513 rotates inwards to a shrinkage state; thus, the second card-feeding pusher 5131 is stopped outside the card-storing groove 502 and the card-lifting groove, and the first card-feeding pusher 5033 moves to one side of the card-holding table 402 and is arranged in a staggered manner with the card-feeding pusher in the card-feeding device, and waits for the next card feeding, as shown in fig. 11 and 12.

After the card feeding is completed, the transmission sleeve 705 is blocked from rotating by the baffle 708 after rotating for one circle, so that the transmission sleeve 705 is prevented from being combined with the driven wheel 704 to transmit torque, the transmission shaft 706 and the driven wheel 704 are separated, and the card feeding assembly stops card feeding.

When the roller a607 moves from the low position to the high position in the cam groove 7032 of the driving wheel 703, the card-raising support plate 601 is raised to the initial position to be flat with the table top, the motor stops rotating, and the movement is ended.
