Description

Technical Field

[0001] The utility model relates to the technical field of mahjong milling machines, in particular to a material delivery mechanism for mahjong milling machines. Background Art

[0002] Mahjong is usually made of small rectangular blocks of bamboo, bone or plastic, with patterns or words engraved on them. Common materials for mahjong blocks include ABS plastic, PVC plastic, PP plastic and PC plastic. During the production process of mahjong blocks, milling devices are required to polish the blocks to make the outer surface of the blocks round and shiny.

[0003] In the existing milling process for mahjong tiles, a positioning device is typically used to hold the tiles, while a milling device is used to mill the outer surface of the tiles. However, this method still has the following disadvantages: During use, the tiles are manually placed inside the positioning device, which not only increases the risk of hand injuries but also reduces processing efficiency. Therefore, we propose a material delivery mechanism for a mahjong milling machine to address this problem. Utility Model Content
