Description

Technical Field

[0001] The utility model relates to the technical field of gold jewelry processing, in particular to a surface treatment device for gold jewelry. Background Art

[0002] Gold jewelry refers to jewelry made of gold as the main raw material. In order to overcome the shortcomings of gold, such as high price, low hardness, single color, easy wear and tear, and crude patterns, some other metal elements are usually added to pure gold to increase the hardness of the jewelry gold, change its color tone and lower its melting point. Sandblasting technology is also very important as one of the surface treatment processes for gold jewelry. After the jewelry is polished, the sandblasting process uses high pressure to spray quartz sand or river sand on all or part of the exposed surface of the jewelry to form a delicate frosted surface. The sandblasting process can make gold jewelry more textured and hazy and soft.

[0003] After searching, the Chinese patent publication number is CN217510024U, which discloses a surface treatment device for gold jewelry. When the gold jewelry needs to be sandblasted, the gold jewelry is first fixed with a clamping assembly, and then the spray can is installed on the moving assembly. After the preparation work is completed, the moving assembly moves up and down, left and right, driving the spray can to move, and sandblasting particles are sprayed from the nozzle to spray the gold jewelry. At the same time, the motor rotates to drive the clamping assembly to rotate, thereby expanding the sandblasting angle, which can reduce the uneven sandblasting of the gold jewelry caused by excessive spraying angle.

[0004] However, during the use of the above patent, when sandblasting gold jewelry, although the sandblasting angle can be expanded, the angle of the clamped gold jewelry cannot be adjusted. Some gold jewelry has decorative patterns, and when sandblasting, the edges and corners of the patterns cannot be completely covered, so there are blind spots for sandblasting. Utility Model Content
