Background

The existing mahjong machine is generally a four-side four-row mahjong machine, and after mahjong pieces are distributed, the mahjong pieces are lifted to a tabletop vertically by being pushed horizontally by a horizontally arranged mahjong lifting plate. By adopting the tile pushing mode, the length of the tile lifting plate is at least equal to the length of the mahjong tile queue, and the tile clamping phenomenon is easy to occur in the rising process of the mahjong tile due to the overlong tile lifting plate; in addition, the horizontal debugging process is complicated and the cost is high when the vertically lifting tile lifting board is assembled with the panel of the mahjong machine.

In addition, the existing four-way four-outlet mahjong machine only has four outlets, and the internal mahjong distributing device can only divide mahjong tiles into four rows of mahjong queues stacked in two layers, and the four rows of mahjong queues are respectively lifted to a table top from the four outlets through the tile lifting plate. When the mahjong game is played, the player also needs to manually grasp the mahjong game (at least 13 mahjong games are usually manually grasped when the mahjong game is played), the automation degree of the machine is low, and the labor intensity of the arms of the player in the mahjong game process is high.

If a set of tile dividing device is directly added in the existing four-outlet mahjong machine to realize no-holding, the tile dividing device occupies too large space in the mahjong machine, and mahjong tiles of larger sizes cannot be used.

Wherein one end of the tile feeding track unit 10 is communicated with a mahjong conveying groove 11, and the mahjong conveying groove 11 is used for conveying shuffled mahjong tiles 200 from the shuffling tray 130 into the tile feeding track unit 10; the stacking mechanism 20 is arranged on the mahjong tile feeding track unit 10, and the stacking mechanism 20 is used for stacking mahjong tiles 200 in the mahjong tile feeding track unit 10 into a plurality of mahjong stacks; the feeding end of the tile distributing rail 30 is communicated with the tile delivering rail unit 10, and the tile distributing rail 30 is used for dividing the mahjong pile into a single-layer mahjong queue positioned in the tile delivering rail unit 10 and a multi-layer mahjong queue positioned in the tile distributing rail 30; the multi-layer mahjong lifting mechanism 40 is respectively in butt joint with the discharging end of the mahjong distributing rail 30, and the multi-layer mahjong lifting mechanism 40 is used for lifting the multi-layer mahjong queues to the tabletop of the mahjong machine through the multi-layer mahjong outlet 110; the single-layer mahjong tile lifting mechanism 50 is arranged on the mahjong tile feeding track unit 10, and the single-layer mahjong tile lifting mechanism 50 is used for lifting a single-layer mahjong tile queue to the tabletop of the mahjong machine through the single-layer mahjong tile outlet 120; the card feeding mechanism 60 is installed in the card feeding rail unit 10 for driving the mahjong tiles 200 to move in the card feeding rail unit 10.

When the mahjong pieces are distributed in the mahjong machine, the shuffled mahjong pieces 200 enter the mahjong piece delivering track unit 10 through the mahjong piece delivering groove 11, the mahjong pieces 200 are stacked into a plurality of three-layer mahjong pieces in the mahjong piece delivering track unit 10 through the stacking mechanism 20, the mahjong piece delivering mechanism 60 pushes the piled mahjong pieces to move along the mahjong piece delivering track unit 10, when the mahjong pieces move to the mahjong piece distributing track 30, the mahjong pieces are separated by the mahjong piece distributing track 30, the mahjong pieces 200 on the two layers above the mahjong pieces form a multi-layer mahjong piece queue, the mahjong pieces 200 on the lower layer below the mahjong pieces form a mahjong piece monolayer queue, and the mahjong pieces are positioned in the mahjong piece delivering track unit 10, so that scientific distribution is realized, and the mahjong piece distributing structure unit is applied to the mahjong machine, so that the multi-layer mahjong piece queue and the single-layer mahjong piece queue are pushed out from the multi-layer mahjong piece outlet 110 and the single-layer mahjong piece outlet 120 of the mahjong machine respectively, and no holding of the mahjong pieces can be realized when the machine is opened.

Referring to fig. 11 to 16, in the present embodiment, the distribution rail 30 is disposed above the card-feeding rail unit 10, and the distribution rail 30 is positioned at the inner side of the card-feeding rail unit 10, so that the internal structure of the mahjong machine can be made more compact without occupying excessive internal space after the distribution structural unit is applied to the mahjong machine, and the mahjong machine can use a larger-sized mahjong tile.

Further, referring to fig. 11 to 16, the outer side wall of the tile distributing rail 30 is connected with the outer side wall of the tile delivering rail unit 10 by a tile distributing plate 31, and the distance between the bottom surface of the tile delivering rail unit 10 and the lower edge of the tile distributing plate 31 is greater than the thickness of a single tile 200 and less than the thickness of two tiles 200 when stacked. Thus, when the stack of three mahjong pieces passes the tile distributing rail 30, the upper two mahjong pieces 200 are blocked by the tile distributing plate 31 and guided into the tile distributing rail 30, and the lowermost mahjong piece 200 moves from the lower edge of the tile distributing plate 31 along the tile distributing rail unit 10.

The output end of the multi-layer card lifting driving mechanism 42 is connected with the multi-layer card lifting plate 41 and is used for driving the multi-layer card lifting plate 41 to rotate so that the free end of the multi-layer card lifting plate 41 is in butt joint with the card distributing rail 30. The shape and the size of the multi-layer card lifting plate 41 are matched with those of the multi-layer card outlet 110, when the multi-layer card lifting driving mechanism 42 drives the multi-layer card lifting plate 41 to lift to a horizontal state, the multi-layer card lifting plate 41 just seals the multi-layer card outlet 110 to form a complete tabletop, and when the multi-layer card lifting driving mechanism 42 drives the multi-layer card lifting plate 41 to rotate downwards, the free end of the multi-layer card lifting plate 41 can be butted with the card distributing rail 30, so that the multi-layer mahjong queues can be conveniently pushed onto the tabletop.

After the multi-layer mahjong queues enter the mahjong distribution track 30, the driving force of the mahjong feeding mechanism 60 does not act on the multi-layer mahjong queues any more, and if the multi-layer mahjong queues are pushed from the inside of the mahjong distribution track 30 to the multi-layer mahjong lifting plate 41 and the tabletop, additional power is needed to be provided. In this embodiment, the multi-deck card lift mechanism 40 further includes a multi-deck card pushing mechanism 43, and the multi-deck card pushing mechanism 43 is used to push the multi-deck mahjong queue from within the distribution track 30 onto the multi-deck card lift plate 41.
