Description

Technical Field

[0001] This utility model relates to the field of equipment technology for the production of lacquerware, and in particular to a fully automatic polishing equipment for lacquer cups. Background Technology

[0002] Lacquerware is a traditional craft made from natural lacquer through dozens of complex processes. Combining practicality and artistry, it is an important representative of China's intangible cultural heritage. The processing of lacquerware requires repeated polishing. Due to the special properties of natural lacquer, water must be continuously added during polishing to ensure the finished product retains its texture and luster. Furthermore, the amount of lacquer removed during each polishing step must be carefully controlled to avoid damaging the surface.

[0003] Cups are a common type of lacquerware, but current technology lacks suitable automatic polishing devices. Most polishing is done manually, with only a single rotating polishing head holding the part to be polished. This process is inefficient and fails to meet the demands of mass production while preserving the properties of lacquer. Therefore, there is a need to develop specialized polishing equipment for cups made of lacquerware. Utility Model Content
