Patent document No. CN200966910Y discloses a slope tile-playing device for a full-automatic mahjong machine, which comprises a table top plate, wherein a tile-playing port is arranged at the center of the table top plate, four rectangular tile-playing ports in a windmill shape are arranged on the table top plate, and are inclined at an angle with the side line of the table top plate, four arc-shaped tile storage grooves which are also arranged in a windmill shape of windmill are arranged below the table top plate, a tile-sending pushing head is arranged at the tail end of each tile storage groove, the pushing head is connected with a pushing head motor through a tile-sending steel wire rope, a supporting plate door strip is arranged on each tile-playing port, one end of each supporting plate door strip is hinged with the tile-playing port, and the other end. 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 conforms to the habits of players; secondly, when the mahjong is played, the whole mahjong pier is not built and then is lifted on the table top, but is pushed on the table top along the slope, so that the space in the machine can be reduced, and the volume of the whole machine can be reduced. However, in the card-delivering device, the whole card storage groove is arranged in a slope shape, the resistance in the card-delivering process is large, the load of a steel wire rope motor is large, a steel wire is easy to shake and break, the card-delivering process is not stable enough, the service life of the steel wire rope is short, the arrangement of the card storage groove, the stacking and pushing machine head and the conveying device (a mechanism for picking up mahjong tiles from a large disk and conveying the mahjong tiles to the stacking and pushing machine head) is unreasonable, the conventional four-side independent stacking and pushing machine head is difficult to push the mahjong tiles to the card inlet of the card storage groove track, and the height of the main.

Patent document No. CN201783185U discloses a chain-driven slope tile discharging device for a full-automatic mahjong machine, which comprises four liftable tile lifting plates hinged with a tabletop, wherein one end of each tile lifting plate is a tile inlet, a conveying belt is arranged outside each tile lifting plate, a stacking and pushing mechanism is arranged on one side of each conveying belt, an arc-shaped tile storage groove is arranged outside each four-side conveying belt, an annular closed chain is arranged below each groove, and vertical chain rods are arranged on each chain at set intervals. Although the mahjong tile discharging device adopts the chain to push the mahjong tiles, the problem of short service life of a steel wire rope is solved, the working noise of the machine is high, the plane size of a main machine is increased, and other defects are not improved.

Patent document No. CN102133480A discloses a full-automatic mahjong machine, which comprises a tile feeding system, a tile lifting system and a tile shuffling large plate, wherein the tile feeding system comprises four tile pushing devices, four tile feeding rails and a chain transmission device. The height of the card sending system is basically equal to that of the card lifting system, so that although the height of the host computer is reduced, the arrangement position of the card lifting system can interfere with the large-disk shuffling and the card sending system to suck mahjong, and the card sending system is only suitable for small mahjong. Moreover, the arrangement of the mahjong outlet of the mahjong conveying system and the mahjong inlet of the mahjong loading track is unreasonable, the mahjong pushing device does not have the mahjong stacking function, mahjong tiles are automatically stacked on the mahjong bearing table surface, and therefore the mahjong tiles are not stacked neatly and are easy to move and misplace, and the mahjong tiles cannot enter the mahjong loading track, and are disordered in the mahjong loading track. In addition, after the horizontal mahjong tile feeding track is adopted, mahjong tiles close to the mahjong tile discharging port of the mahjong tile feeding track are very easy to fall out of the mahjong tile discharging port and fall back to the large shuffling tray; the chain and the mahjong-serving flag wheel are adopted, so that the noise is high.

In the automatic mahjong machine disclosed in patent documents with publication numbers CN201906453U and CN201949619U, the mahjong storage plate in the mahjong storage track of the mahjong machine is obliquely arranged, one end of the mahjong storage plate is butted with the mahjong bearing plate, the mahjong stacking and pushing head pushes the mahjong tiles on the mahjong bearing plate to the mahjong storage plate, and after the mahjong tiles on the mahjong storage plate are arranged in a row, the mahjong loading and pushing head pushes the whole row of mahjong tiles to the mahjong loading assembly; because the dodging groove is formed in the stacking pushing head, and the push rod is arranged on the upper pushing head, the two pushing heads can be arranged in a vertical crossing mode, and the two pushing heads can be completely avoided from each other through the dodging groove when pushing the cards respectively. However, since the card storage rail passes above the conveying part of the card feeding device, the height of the main machine of the mahjong machine is high (the heights of the card feeding device and the card loading device are overlapped), and the L-shaped card storage rail is short, so that the universality is poor.

The automatic mahjong machine disclosed in the patent documents CN103861280A and CN104645608A also has the problems of high height of the main machine (the height of the card feeding device and the height of the card loading device are overlapped), short L-shaped card storage track and the like. Moreover, after the horizontal mahjong tile feeding track is adopted, mahjong tiles close to the mahjong tile discharging port of the mahjong tile feeding track are very easy to fall out of the mahjong tile discharging port and fall back to the large shuffling tray; the wire rope is adopted to drive the mahjong tile pushing head to move, the wire rope and the side wall of the track are seriously rubbed, and the service life is short.

The patent document with publication number CN204699375U discloses an automatic mahjong machine with an improved structure, which comprises a mahjong conveying system, a mahjong loading system, a mahjong lifting system and a large shuffling tray, wherein the mahjong conveying system comprises four mahjong conveying mechanisms, each mahjong conveying mechanism comprises a transmission frame and a conveying belt fixed on the transmission frame, the four mahjong conveying mechanisms are sequentially connected to form a rectangular structure, and the large shuffling tray is arranged in the four mahjong conveying mechanisms. The mahjong tile feeding tracks are all of large arc structures, friction force between mahjong tiles and the mahjong tile feeding tracks is reduced, and high mahjong tile feeding speed and low mahjong tile feeding noise are guaranteed. And moreover, the arrangement positions of the card feeding system and the card delivering system are subjected to avoidance partial overlapping design, so that the height of the host is reduced. However, because the tile feeding device adopts a straight line to feed and discharge the mahjong tiles, the tile outlet of the tile feeding device and the tile inlet of the tile feeding track cannot be reasonably arranged, the tile pushing resistance of the stacking and pushing device is large, the tiles are easy to be clamped, and the size of the table top of the mahjong machine is increased due to the large arc-shaped tile feeding track.

Serial patent documents with publication numbers CN105381604, CN105381604 and the like disclose a mahjong machine, which comprises a central lifting component, a shuffling large disc and a mahjong scraping device which are positioned in the center of a bottom plate of a machine frame, wherein four groups of mahjong picking and carrying systems are arranged around the periphery of the shuffling large disc, each mahjong picking and carrying system comprises a mahjong conveying device used for picking and conveying mahjong tiles from the shuffling large disc one by one, a mahjong pushing device used for stacking the mahjong tiles into a pier and pushing out the pile, and a slope mahjong discharging device used for conveying the arranged multi-pier mahjong tiles to the table surface of the mahjong machine along a slope, and the slope mahjong discharging device comprises a mahjong loading component and a mahjong lifting component; the mahjong tile feeding assembly comprises a mahjong tile storage groove for storing multi-pier mahjong tiles, the mahjong tile storage groove is provided with at least one arc-shaped bend, a mahjong tile feeding guide rail is installed on the inner side wall of the mahjong tile storage groove, a mahjong tile feeding pushing head is arranged on the mahjong tile feeding guide rail in a sliding mode, and the mahjong tile feeding pushing head is driven by a steel wire rope mahjong tile feeding driving mechanism to slide along the mahjong tile feeding guide rail. This solution, as practiced by the applicant, still suffers from the following drawbacks:

1. the mahjong tile feeding push head slides along the mahjong tile feeding guide rail and is driven by a steel wire rope, and the problems of large friction resistance, small mahjong tile pushing force, large motor load, complex structure, poor reliability, high manufacturing cost, high use and maintenance cost and the like still exist.

2. The mahjong sending device and the mahjong lifting device are still overlapped to a certain degree, so that the height of the whole mahjong machine is increased, and the mahjong machine cannot be used for a light and thin mahjong machine.

3. The setting position of the tile lifting port of the adjacent tile picking and carrying system is greatly limited, and the use comfort of the mahjong machine is influenced. Taking a 48mm mahjong tile used by a mahjong machine with 85cm square as an example, four rows of mahjong tile walls which are directly lifted from a square tile lifting port to a table top are arranged in a windmill shape, the distance between two opposite rows of mahjong tile walls is more than 35cm (the distance between two opposite tile lifting ports is 35cm), so that the left hand area where a player is accustomed to placing bars and tiles is very small (namely the distance between the mahjong tile walls and the table top frame is too small), the player is required to move the mahjong tile walls to be free from the bar area, and the use comfort is influenced.
