Description

Technical Field

[0001] The utility model relates to the technical field of bracelet grinding and polishing, in particular to a bracelet grinding and polishing device. Background Art

[0002] Bracelets are ring-shaped ornaments worn on the wrist made of gold, silver, jade, etc. According to the structure, they can generally be divided into two types: one is a closed ring, mostly made of jade; the other is a bracelet with ports or several chain pieces, mostly made of metal. According to the production materials, they can be divided into gold bracelets, silver bracelets, jade bracelets, gemstone bracelets, etc. Among them, jade bracelets need to be polished during the production process and after long-term wearing to make the surface smoother and more delicate.

[0003] Some bracelet grinding and polishing devices currently on the market: for example, the utility model patent with authorization announcement number CN219485310U discloses a bracelet polishing device, which rotates a transmission rod No. 1 through a No. 1 motor, and then rotates the transmission gear through the No. 1 transmission rod. The rotation of the transmission gear drives the meshing gear plate to rotate, and then the three sliding columns move and shrink simultaneously through the No. 1 slide groove and the No. 2 slide groove, and the roller moves and shrinks to fix the bracelet. The operation is simple, and the fixing and clamping are very convenient, which increases the labor efficiency of the polishing personnel. Turn on the No. 2 motor to rotate one of the rollers through the sliding column, and the rotation of the sliding column drives the bracelet to rotate, so that the bracelet automatically rotates during the polishing process. While the operation is convenient, the uniform rotation can better polish the bracelet, making the polishing of the bracelet more uniform, which greatly improves the work quality and use efficiency compared with the traditional device. However, since the single polishing wheel of the device can only grind and polish part of the ring body of the bracelet during one processing, the other parts of the bracelet are not processed. The bracelet needs to be removed, the position of the polishing wheel is adjusted, and the bracelet is installed for multiple polishing, which is more troublesome and needs to be improved.
