Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing equipment, in particular to a sheet metal electrostatic spraying device with a powder recovery function. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for metal sheets. It has the characteristics of light weight, high strength, low cost, and good mass production performance. Therefore, sheet metal is an indispensable component in the fields of machinery, electronic appliances, communications, and automobile industries. With the increasing application of sheet metal, the appearance quality and corrosion resistance of sheet metal parts are particularly important. Electrostatic spraying can provide sheet metal parts with a uniform, smooth, and beautiful coating, enhance their corrosion resistance, wear resistance, aging resistance, and other properties, and improve the service life and safety of the product. Its principle is to use the corona discharge phenomenon to adsorb powder coating on the workpiece. The process is that the powder coating is fed into the spray gun with the help of compressed air, and high-voltage static electricity is added to the front end of the spray gun. Due to corona discharge, dense charges are generated near it. When the powder is sprayed from the gun nozzle, charged coating particles are formed. Under the action of electrostatic force, it is sucked to the workpiece with the opposite polarity.

[0003] Nowadays, most spraying of workpieces is done manually by spraying the workpiece up and down with a spray gun, which is time-consuming and labor-intensive, and reduces work efficiency. At the same time, during the spraying process, some powder will always fail to be absorbed by the workpiece and fall to the ground, causing great harm to the health of the workers.
