Description
Technical Field
The utility model relates to a mahjong machine technical field, especially a dual-purpose strip mechanism of dialling of positive and negative rotation.
Background
Mahjong has a wide range of players in China and the world, is a popular entertainment tool, mahjong machines capable of automatically shuffling and stacking mahjong are popular, and household mahjong machines gradually enter thousands of households along with improvement of living standard. For the household mahjong machine, the most important is to ensure silence. The prior mute mahjong machine mainly buffers the collision of mahjong tiles to the shuffling cylinder by sticking thicker lining materials in the shuffling cylinder and absorbs the noise in the shuffling cylinder; or reduce the speed of operation of the various components, such as the shuffling platter, so that the speed of impact of the mahjong with the components during shuffling is reduced, thereby reducing noise. However, the former addresses the symptoms and does not address the root cause, and the latter affects the shuffling rate.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide a dual-purpose card-strip shifting mechanism capable of rotating positively and negatively.
