Description

Tile pushing and pulling mechanism and mahjong machine

Technical Field

The invention relates to the field of mahjong machines, in particular to a tile pushing and pulling mechanism and a mahjong machine.

Background

The mahjong is a traditional entertainment and leisure activity for the public, and the existing automatic mahjong machine needs to pick up and stack the magnetic mahjong tiles in the shuffling tray, then arrange the tiles well and finally send the tiles to a mahjong table for players to entertain.

When the existing automatic mahjong machine realizes pushing and pulling mahjong pieces, the automatic mahjong machine is usually realized by two independent mechanisms, and the working principle is as follows: after the double-layer mahjong pieces are stacked in the mahjong piece stacking groove, the motor controls the push plate to push out the mahjong pieces, then the mahjong pieces are reset, and the actions are repeated. After all mahjong tiles are stacked, the whole mahjong tiles are pulled to the tile lifting mechanism through the tile pulling mechanism, and the tile pulling mechanism is reset through the resetting mechanism after the tile pulling operation is completed. The number of the driving motors which need to be adopted is too large, so that the manufacturing cost cannot be reduced, the failure probability is relatively high, the stroke of the tile pulling mechanism is long, a corresponding reset mechanism is needed, the reset mechanism cannot influence the normal operation of other mechanisms, and the requirement on the design of the inner space of the automatic mahjong machine is high. Moreover, each action of each side of the existing mahjong machine is generally driven by an independent driving mechanism (more than ten motors or cylinders are needed in the traditional multi-opening automatic mahjong machine), so that the manufacturing cost is increased, the installation and production efficiency is low, and the difficulty of daily maintenance is increased. Meanwhile, the large number of the driving mechanisms also enables the equipment to be large in size and heavy in weight, and the storage and transportation cost is increased.

Patent zl201210537155.x discloses a mahjong machine tile feeding mechanism, which adopts a motor to drive a tensioned steel wire to drive a tile pushing head to pull tiles or reset, and does not need an additional reset mechanism. But because it adopts the structure of the guide piece of the card pushing head, and the card pushing head is positioned on the upper part of the inner side surface of the track in the drawing, the friction force between the card pushing head and the guide piece of the card pushing head is larger in the using process, the stability is poorer, and the phenomenon of deadlocking is very easy to occur when the card pushing head turns round, so the track patch with smooth surface, which is made of wear-resistant material, is arranged on the track. And the mechanism can not be simply combined with the mahjong stacking groove to realize multifunctional operation, and the mechanism can only realize the mahjong pulling function but can not realize the mahjong pushing function. Meanwhile, the tile lifting mechanism on each side of the existing mahjong machine needs an independent motor to drive, so that the production cost is greatly increased.

The applicant has filed an improved full-automatic mahjong machine 201910673023.1 which describes a tile pulling assembly, wherein the tile pulling assembly is driven by a gear at the top of a tile channel to move back and forth. Because the card pulling mechanism moves along the rack, the motor needs to move along with the card pulling assembly, the load of the motor is large, and the resistance is large when the card pulling mechanism is bent. And because the motor needs to move, more activity spaces need to be reserved in the mahjong machine for the motor to move, and the difficulty of space design is increased.

when the mahjong tiles are pulled, the push plate 101 is driven by the slide block 1 to pull all the mahjong tiles forward along the track 3 until all the mahjong tiles are pulled into the designated area.

The traditional mahjong stacking and pushing actions use a driving mechanism to be matched with a sensor for linkage, and then are matched with an independent mahjong pulling mechanism to pull the stacked mahjong into a bridge plate. This application will push away the tablet and draw tablet mechanism and magnetic fold tablet groove and carry out organic combination, and space design is more optimized, and interference is littleer between each mechanism, and the position is laid also more nimble.

POM is polyformaldehyde, commonly known as Saikang, and has high strength, high rigidity, high elasticity and high wear resistance. The mechanical property is excellent, the specific strength can reach 50.5MPa, the specific rigidity can reach 2650MPa, and the specific rigidity is very close to that of metal. The POM has small friction factor, good wear resistance, large limit PV value and good self-lubricating property.

In order to ensure the smoothness in the card pushing process, a side plate 102 is further arranged on one side of the pushing plate 101. In the tile pushing process, the side plates can effectively prevent the tile sucking mechanism from sending the mahjong tiles into the tile stacking groove from the side surface, and the continuity and smoothness of the tile pushing process are guaranteed.
