Synchronous belt assembly, tile supply device and mahjong machine

Abstract

The utility model provides a synchronous belt assembly, a tile supply device and a mahjong machine, because the synchronous belt assembly is arranged between a tile suction wheel and a tile stacking device, a synchronous belt is not sleeved on the tile suction wheel any more, but is only used for conveying mahjong tiles at a certain distance between the tile suction wheel and the tile stacking device; therefore, the problem that the mahjong tiles frequently collide with the synchronous belt when the mahjong tile sucking wheel sucks the mahjong tiles can be avoided, the problems that the synchronous belt accelerates aging and even is broken and the synchronous belt deviates due to collision are avoided, and the problems that the synchronous belt rubs other parts around and makes noise when deviating can be further avoided. Moreover, the middle parts of the two synchronous belt driven wheels are provided with guide bulges, and the inner surface of the synchronous belt is provided with a circle of guide groove matched with the guide bulges, so that the synchronous belt driven wheels can be guided and limited upwards through the matching of the guide bulges and the guide groove, and the deviation of the synchronous belt is further avoided; therefore, the service life of the synchronous belt can be prolonged, and long-term stable work of the card supply device is guaranteed.
