A jewelry automatic sorting device

Abstract

The invention provides an automatic sorting device for jewelry, which is used for separating jewelry and abrasives after grinding and polishing, and includes a frame, a sorting mechanism and a leveling drum. Chain; sorting chain is used to undertake the mixture of jewelry and abrasives. The sorting chain includes a chain conveyor belt sleeved on the sprocket and a number of support pins evenly arranged on the side of the chain conveyor belt facing away from the sprocket. The wheel can rotate relative to the frame under force to transfer the mixture through the sorting chain; the leveling drum is installed on the rack, and the vertical distance between the leveling drum and the support pin is only for a layer of abrasive to pass; leveling The drum can rotate relative to the frame under force to spread the mixture of jewelry and abrasives on the sorting chain. Through a number of support pins, the jewelry can be dropped to the chain conveyor under the action of its own gravity, and the abrasives can be removed. Support on top of support pins for separation. It can replace manual automatic sorting of jewelry and abrasives.

Description

technical field [0001] The invention relates to jewelry processing equipment, in particular to a jewelry automatic sorting device. Background technique [0002] During the processing of jewelry such as rings, it is usually necessary to polish the jewelry to improve the smoothness of the metal jewelry surface. Vortex polishing machine is a common polishing equipment for rings and other jewelry polishing. It makes jewelry and abrasives grind each other, so as to achieve multiple effects such as removing burrs, grinding marks, scale, chamfering and polishing, and cleaning. The water flow will not collide with each other and will not damage the surface. After the jewelry grinding and polishing process, it is necessary to separate the jewelry and abrasives. After polishing jewelry such as rings, it is necessary to avoid excessive collision and extrusion to prevent damage to the surface of the jewelry during screening. Therefore, vibration cannot be used. The sieve and other dev...

AI Technical Summary

Problems solved by technology

After the jewelry grinding and polishing process, it is necessary to separate the jewelry and abrasives. After polishing jewelry such as rings, it is necessary to avoid excessive collision and extrusion to prevent damage to the surface of the jewelry during screening. Therefore, vibration cannot be used. The sieve and other devices automatically sort jewelry and abrasives; and the vibrating screen is screened by reciprocating vibration, which has a large equipment loss and a short service life.

In the jewelry processing industry, most factories still use manual sorting of polished jewelry from abrasives. The workload is large, the sorting efficiency is low, the labor intensity of workers is high, and it takes more labor and the production cost is higher.
