The invention relates to the technical field of mahjong machine manufacturing, in particular to an eight-mouth mahjong machine and a slope tile feeding mechanism thereof.

Background

The existing full-automatic mahjong machine integrates the functions of shuffling, dice throwing and the like, and provides great convenience for people to deal with the cards. However, the existing full-automatic mahjong machine is basically provided with only four outlets, mahjong is conveyed to a mahjong table top from the four outlets, and manual tile pushing, tile cutting and tile stacking are still needed when the mahjong is played, so that the operation is troublesome, the situation of wrong tile cutting can occur, and the mahjong can only be reshuffled.

In order to solve the problem, the Chinese invention patent with the patent number of CN200920118048.7 discloses an automatic mahjong machine, which comprises a mahjong machine tabletop and a host machine arranged below the mahjong machine tabletop, wherein an inner lattice plate is arranged in the host machine, outer lattice plates are arranged on the outer sides of the inner lattice plates, the 4 outer lattice plates are connected into an annular track for bearing mahjong tiles through 4 arc transition sections, an annular pushing device for pushing the mahjong tiles is arranged above the annular track, a sliding rail is arranged below the mahjong pushing machine head, the mahjong pushing machine head is arranged between an inner pushing opening and an outer pushing opening in a sliding mode through motor driving, and a rocker device for guiding the mahjong tiles on the annular track to the mahjong machine tabletop is arranged on the mahjong machine tabletop right above the 4 outer lattice plates. According to the automatic mahjong machine, thirteen game participants on the four sides of the outer side can grasp the cards, so that the game participants can obtain more convenient, quicker and more comfortable game experience.

The tile lifting principle of the automatic mahjong machine is as follows: when 13 cards are pushed fully, the control system gives out instructions, and the card pushing head drives the card pushing head to move to the inner card pushing port, so that the card pushing head starts to push cards. When the card pushing head is pushed by a certain number of piers (different according to the total number of piers for playing cards), the motor of the flat pushing assembly rotates to drive the guide plate to fall down, and then the second layer of cards are pushed. When the 4 outer grid plates are fully pushed by 13 cards and the card pushing heads are all moved to the inner card pushing ports, the control system sends out signals, and the steel wire rope motor starts to rotate to drive the cards to walk on the annular track and to a position waiting for card feeding. When 1 inner lattice plate is folded, the conveying motor is turned upside down, the residual cards in the conveying device are returned to the large tray and sent to the card feeding ports of other conveying devices until the last 4 inner lattice plates are folded.

The automatic mahjong machine has the following defects:

1) The mahjong machine is blocked because the mahjong head can miss the tile pushing opening when the tile pushing head is arranged at the inner tile pushing opening;

2) The movement of the card pushing head from the outer card pushing port to the inner card pushing port and from the inner card pushing port to the outer card pushing port requires another driving device such as a motor drive, which is costly.

The mahjong machine can realize a method of arranging mahjong tiles in stages, and when the mahjong tiles are stored, the mahjong tiles are picked up by the tile feeding device and pushed into the tile storage groove by the tile pushing device; when the mahjong machine receives a first tile-feeding signal, the tile-feeding supporting plate of the tile-feeding device descends, the tile-feeding pushing head firstly pushes part of mahjong tiles (generally six piers and half or thirteen mahjong tiles) in the tile-storing groove to the tile-feeding supporting plate, the tile-feeding supporting plate lifts the mahjong tiles to the tabletop, and a player takes the mahjong tiles on the tabletop; after receiving the second tile-feeding signal, the tile-feeding supporting board descends, the tile-feeding pushing head pushes the remaining mahjong tiles in the tile-storing groove to the tile-feeding supporting board, and the tile-feeding supporting board is lifted to feed the mahjong tiles to the table top. By adopting the scheme of pushing the mahjong pieces twice in stages, the functions of the eight mahjong pieces can be realized by using the structure of the existing four mahjong pieces, but because the tile pushing head occupies a trick position in the tile storage groove in the tile lifting device from tile feeding to tile lifting, the tile storage groove length of 18-19 trick is required at 17 trick, when the mahjong pieces with the mode are used for playing larger tiles, the track length of the required mahjong pieces is longer, and the mahjong pieces with the size of the existing mahjong pieces can not be realized, so that the length of the tile storage groove of the mahjong pieces needs to be reduced as much as possible.

The utility model patent with the publication number of CN108635827A discloses a tile feeding structure of a three-layer mahjong machine, which comprises a circular single-layer tile channel and a circular double-layer tile channel which are arranged in an up-down overlapping manner, wherein a motor seat is arranged on the single-layer tile channel, a second motor is arranged on the motor seat through a gear, a first motor is arranged on the motor seat through a rotating shaft, a single-layer tile turntable is connected with a driven shaft on the motor seat through a bearing, teeth of the single-layer tile turntable are meshed with the gear, a single-layer tile deflector rod is arranged on the single-layer tile turntable, and a tile adjusting ring and a double-layer tile deflector rod arranged in the tile adjusting ring are arranged on the double-layer tile channel; after the three-layer cards enter the card channel, the second motor drives the gear to drive the single-layer card rotating disc to rotate, and the single-layer card shifting rod of the single-layer card rotating disc pushes the cards of the single-layer card channel to the table top of the mahjong machine; after the three-layer cards enter the mahjong machine, the first motor drives the rotating shaft to drive the double-layer card shifting rod to rotate, and the cards of the double-layer card machine are pushed to the table top of the mahjong machine. The mahjong machine with the structure is characterized in that three mahjong pieces are piled up to form a pier, one pier of mahjong pieces is divided into a single-layer (one piece of mahjong piece) and a double-layer (two piece of mahjong piece) and then sent to the table top of the mahjong machine after being respectively sent to the single-layer mahjong piece passage and the double-layer mahjong piece passage, the required track length of the mahjong machine can be effectively shortened by the arrangement, but the occupied height of the mahjong machine is larger, the whole height of the mahjong machine with the structure is larger, particularly when playing larger mahjong pieces, the mahjong machine with the existing machine type size cannot be realized, and when one pier of mahjong pieces is divided into a single-layer (one piece of mahjong piece) and a double-layer (two piece of mahjong piece) and sent to the single-layer mahjong piece passage and the double-layer mahjong piece passage respectively, the precision required for the track division is extremely high, and the mahjong machine is blocked due to slight deviation; on the other hand, two motors are respectively used for directly or indirectly driving two tile pushing heads to push mahjong tiles in the single-layer tile channel and the double-layer tile channel, so that the structural complexity and the control complexity of the mahjong machine are increased, and the production cost of the mahjong machine is increased.

Specifically, the card pushing surface on the card pushing head 612 includes a vertical surface and an inclined surface 61232. Further preferably, the vertical surface and the inclined surface 61232 are in smooth transition; when the card-feeding pusher head 612 pushes a card in the first card-feeding guide rail 63, the card-pushing surface thereof is a vertical surface in the horizontal first linear guide rail 6311 and the second linear guide rail 6321, and the card-pushing surface thereof is an inclined surface 61232 in the first arc guide rail 6312 and the second arc guide rail 6322 which are inclined upward.

The hinge type and torsion spring reset are adopted, the structure is simple and reliable, the volume is small and exquisite, and the cost is low.

And for four slope tile feeding mechanisms 6 which are distributed in a rectangular shape in the mahjong machine:

The four first card feeding guide rails 63 in the four slope card feeding mechanisms 6 shown in fig. 20 are connected end to enclose a quadrangle, and the head-to-end connection positions of two adjacent first card feeding guide rails 63 are arranged in a staggered manner up and down; to maximize space utilization and to make room for the second pusher head 74, facilitating the pushing of cards by the second pusher head 74.

The arrangement is that the four first card-pushing rails 63 enclose a rounded rectangle and are arranged in a staggered manner, so that the card-pushing tracks of the four card-pushing heads are overlapped in the process of pushing cards on a slope, that is, the movement track of the initial section of one card-pushing head 612 is overlapped with the movement track of the final section of the card-pushing head 612 on the subsequent card-pushing head in the horizontal direction, but one card-pushing head 612 needs to be pushed horizontally in the initial section and needs to be lifted in the final section, and therefore, the adjacent first rails 64 should be positioned below the first arc rail 6312 and the second arc rail 6322 respectively, so as to avoid overlapping card-pushing tracks.

Specifically, a second card feeding motor 68 is further provided, and the second card feeding motor 68 is located at the outer side of any one slope card feeding mechanism 6 and is in transmission fit with the card feeding chain 611.

Specifically, the slope card feeding mechanism 6 further comprises a card feeding chain, the second card feeding guide rail comprises an inner guide rail and an outer guide rail which are distributed on the inner side and the outer side of the bottom groove, the inner guide rail comprises a third linear guide rail and a third arc guide rail which are horizontally arranged, and the outer guide rail comprises a fourth linear guide rail and a fourth arc guide rail which are horizontally arranged; the tile feeding chain is positioned in the bottom groove between the inner guide rail and the outer guide rail and is matched with the tile feeding track of the mahjong tile.
