High-voltage electrostatic oiling system

Abstract

A high-voltage electrostatic oiling system relates to spray coating devices used on production lines, and aims to solve the problems in the prior art that outer surfaces of steel belts, steel tubes and steel wires are not coated with paint uniformly, and the paint loss is large. The high-voltage electrostatic oiling system includes a high-voltage electrostatic generation device, an oiling box, an oil supply device, a workpiece conveying device, a rotary cup driving device, a control unit and a recovery device; the oiling box is provided with a box body, a through hole is formed at the center of the top of the box body, the rotary cup driving device is arranged above the through hole, a rotary cup is arranged in the through hole, a driving output end of the rotary cup driving device is communicated with a driving input end of the rotary cup, and a cup mouth of the rotary cup faces downward to an inner cavity of the oiling box; the oiling device comprises an oil barrel, an air compressor, a pressure gauge, an electromagnetic valve, two oil output valves and two oil nozzles; the control unit includes a controller and a display screen; and an input port of the recovery device is communicated with the inner cavity of the oiling box. The high-voltage electrostatic oiling system is suitable for oiling various production lines continuously.

Description

Problems solved by technology

The purpose of the present invention is to provide a high-voltage electrostatic oiling system to solve the problems of uneven paint coating and large paint loss on the outer surface of existing steel strips, steel pipes, and steel wires.

The present invention uses one paint spraying device to replace multiple paint spraying devices in the existing production line, and solves the problem of uneven paint spraying in overlapping areas caused by multiple paint spraying devices working at the same time; the present invention utilizes the principle of electrostatic adsorption , the negative high voltage is connected to the rotary cup, and the oil, paint or anti-corrosion material is sprayed and charged; through the adsorption of the sprayed paint by the workpiece after charging, the paint is evenly coated on the outer surface of the workpiece The purpose of the invention; the present invention reclaims the residual paint in the paint spraying process by the recovery device of the paint, and recycles it, so that the utilization rate of the paint is increased to 95% from 65% of the prior art
