Description

Technical Field

[0001] This utility model relates to, but is not limited to, the field of powder coating processing equipment, and particularly to a powder coating processing sieving device. Background Technology

[0002] In the production process of powder coatings, sieving equipment is needed to separate coarse and fine particles after crushing. The coatings that have been sieved are of better quality and have better adhesion to the surface treatment of workpieces. Therefore, sieving is a key process in powder production.

[0003] In existing technologies, the sieving of powder coatings generally uses a vibrating motor in conjunction with a screen to classify particles of different sizes by vibration. During the sieving process, coarse particles move towards the edge of the screen under the action of the vibrating motor, and the moving speed is closely related to the vibration frequency of the vibrating motor. After the fine particles are sieved, the coarse particles still need to be sieving for a certain period of time under the action of the vibrating motor before they can be discharged from the coarse material outlet of the screen. This reduces the efficiency of sieving to a certain extent and leads to a longer production cycle. Utility Model Content
