Description

Technical Field

[0001] The utility model relates to the technical field of jewelry processing, and more specifically, to a gold bracelet sand rolling machine. Background Art

[0002] At present, after the gold bracelet is processed, in order to perform surface treatment on it, a sand rolling machine is mostly used. When performing surface treatment on the bracelet, the bracelet is fixed by the sand rolling machine and driven to roll, and the friction member held by the staff is in contact with the gold bracelet, so as to realize the surface treatment of the gold bracelet.

[0003] However, in the existing sand rolling machine applied to gold bracelets, during operation, different molds need to be equipped to install gold bracelets with different diameters. In actual operation, the mold that fits too closely to the inner circle of the gold bracelet, although it has a better fixing effect, is not convenient for the staff to perform surface treatment on the inner side of the gold bracelet. After the surface treatment on the outer side is completed, the mold needs to be replaced, which is inconvenient in actual operation, resulting in the problem that the surface treatment operation for gold bracelets is more laborious. In view of this, we propose a gold bracelet sand rolling machine. Summary of the Utility Model
