Description

Technical Field

[0001] The utility model relates to the field of electrostatic plastic spraying machines, in particular to an electrostatic plastic spraying machine with an anti-blocking structure. Background Art

[0002] Electrostatic spraying machine is an industrial equipment. Through the design of electrostatic control, spray gun and powder supply device, the surface of the object is coated. The electrostatic spraying machine consists of high-voltage power supply, spray gun, nozzle, atomizer, powder barrel, controller and output pipe. When in use, first put the powder coating (spraying raw material, commonly known as plastic powder) into the powder barrel, and suck the coating into the atomizer through the output pipe during the liquefaction process. After atomization, it is sprayed from the spray gun and nozzle to the surface of the workpiece. The powder coating will clump. One is that it is under pressure during storage, and the other is that the heat generated by the electrostatic spraying machine will cause the temperature inside the powder barrel to be different from the outside temperature.
