Description

Technical Field

[0001] This utility model relates to the technical field of equipment for the production of lacquer handicrafts, and in particular to a fully automatic polishing equipment for lacquer beads. 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, with round beads being a relatively common type of lacquerware.

[0003] Due to the unique properties of natural lacquer, water needs to be continuously added during polishing to ensure that the texture and luster of the lacquerware are visible after polishing. Furthermore, the amount of material removed during each polishing session must be carefully controlled to avoid damaging the surface. This makes traditional round bead-type polishing devices unsuitable for mass production of lacquerware. Currently, simpler polishing devices are typically used for manual processing one piece at a time, resulting in low efficiency and difficulty in meeting the production capacity requirements of large-scale production while preserving the characteristics of the lacquer. Therefore, there is a need to develop specialized polishing equipment for lacquerware. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide a fully automatic polishing equipment for lacquer beads, which can precisely adjust the polishing feed and polishing pressure, and can process multiple round beads at once, thereby greatly improving polishing production efficiency while ensuring the characteristics of lacquer handicrafts.
