Electrostatic spraying device for cabinet cold-rolled steel plate and working method thereof

Abstract

The invention discloses an electrostatic spraying device for a cabinet cold-rolled steel plate and a working method. The electrostatic spraying device comprises a steel plate conveying unit, a steel plate cleaning unit, a four-station automatic spraying unit, an automatic reciprocating spraying unit, a first manual checking and supplementary spraying unit, a second double-station manual supplementary spraying unit, a heat preservation oven unit and a dust removal unit. According to the electrostatic spraying device for the cabinet cold-rolled steel plate, through continuous spraying, an electrostatic field is formed between a spraying gun and a workpiece, an air ionization area is formed by the electric field force borne by coating particles and the electrostatic field, corona discharge is generated, and the coating particles move towards the surface of the workpiece with the polarity and are deposited on the surface of the workpiece to form a uniform coating film. According to the working method of the electrostatic spraying device for the cabinet cold-rolled steel plate, the working principle is simple and easy to implement, the automation degree in the working process is high, less manpower is required, the production efficiency is improved, and the working method is suitable for industrial large-scale application.
