Tiles-lifting system of fully-automatic mah-jong machine

Abstract

The invention relates to a tiles-lifting system of a fully-automatic mah-jong machine. The system comprises a tiles-lifting bracket, a tiles-lifting motor, a tiles-lifting rocker arm and a tiles-lifting plate, wherein the tiles-lifting bracket is grooved; one end of the tiles-lifting bracket is used for lifting tiles, and an upper edge of the other end of the tiles-lifting bracket is hinged with one end of the tiles-lifting plate; a wheel groove is formed at a tiles-lifting end at the bottom of the tiles-lifting bracket; a notch is formed at the other end of the tiles-lifting plate; the tiles-lifting motor is fixed on an outer wall of the middle of the tiles-lifting bracket; a motor shaft of the tiles-lifting motor passes through the outer wall of the bracket and is connected with one end of the tiles-lifting rocker arm fixedly; and the other end of the tiles-lifting rocker arm is connected with the bottom of the tiles-lifting plate slidably. In the tiles-lifting system of the fully-automatic mah-jong machine, the motor shaft of the tiles-lifting motor passes through the outer wall of the bracket and is connected with the one end of the tiles-lifting rocker arm fixedly, so that the tiles-lifting motor can drive the tiles-lifting rocker arm directly with no need of any other transmission systems by adopting a structure. The system provided by the invention is simple in structure, safe and reliable, and cannot shorten the service life of the mah-jong machine due to abrasion of accessories.

Description

technical field [0001] The new type relates to a card raising system of a fully automatic mahjong machine, in particular to a card raising system of a fully automatic four-socket mahjong machine. Background technique [0002] The card raising system of the traditional automatic mahjong machine is to install a card raising rocker arm at the two ends of the card raising board respectively, a card raising motor is arranged between the two card raising rocker arms, and a gear is arranged between the motor and the card raising rocker arm. The transmission mechanism, the motor drives the gear to rotate, and the gear transmits the kinetic energy to the card-raising rocker arm. Through the rotation of the card-raising rocker arm, the card-rising board with mahjong tiles is lifted up to complete the card-raising. Under this structure, the force of the weight of the mahjong tiles on the lifting board will be completely applied to the gear between the motor and the lifting arm. Long-te...

AI Technical Summary

Problems solved by technology

Under this structure, the force of the weight of the mahjong tiles on the lifting board will be fully applied to the gear between the motor and the lifting arm. Long-term work is likely to cause deformation or broken teeth of the gear, especially when there is an external force. When acting on the ascending board, the possibility of gear deformation or tooth breakage increases, and people usually spend a long time playing mahjong, and they may accidentally apply external force to the ascending board, resulting in a mahjong machine. The function of raising cards fails, shortens the service life of the mahjong machine, and brings great inconvenience and economic losses to users
