Plastic spraying equipment capable of preventing paint from caking for tubular electromechanical parts

Abstract

The invention discloses plastic spraying equipment capable of preventing paint from caking for tubular electromechanical parts. The plastic spraying equipment comprises a powder supply device communicating with a feed port of a first air pipe and air supply equipment communicating with an air inlet of a second air pipe, a discharge port of the first air pipe, an air outlet of the second air pipe and an inlet of a third air pipe are in communication through a three-way joint, and an outlet of the third air pipe is in communication with a feed port of a spraying unit; a rotatable crushing unit is arranged on the third air pipe, a clamping unit for clamping the tubular part is rotatably arranged below an L-shaped supporting frame, and the clamping unit can drive the crushing unit capable of crushing the caked coating to rotate through rotation; and the spraying unit is arranged below the L-shaped supporting frame in rotating and lifting modes, and a lifting path of a spraying gun of the spraying unit can be located in the tubular parts. The inner walls of the parts are sprayed by arranging the lifting spraying unit, the caked coating is crushed by arranging the crushing unit, powder supply and plastic spraying are conducted, and the plastic spraying quality is guaranteed.

Description

technical field [0001] The invention relates to the field of electromechanical plastic spraying, in particular to a plastic spraying equipment for preventing coating agglomeration of tubular electromechanical parts. Background technique [0002] Plastic spraying is a surface treatment method that sprays plastic powder on parts. Plastic spraying is also what we often call electrostatic powder spraying coating, and its treatment process is a kind of metal surface treatment decoration technology that has been widely used in the world since the 1980s. Compared with ordinary painting surface treatment, this technology has the advantages of advanced technology, energy saving and high efficiency, safety and reliability, and bright color. Therefore, it is often used in the fields of light industry and home decoration. Its working principle is to charge the plastic powder through high-voltage electrostatic equipment, and under the action of the electric field, spray the paint onto ...

AI Technical Summary

Problems solved by technology

[0003] Existing plastic spraying equipment can't achieve anti-caking after powder gas mixing by setting an anti-caking structure in the powder supply device, and can't guarantee the quality of spraying; existing plastic spraying equipment only uses a single rotating part or rotating nozzle Spraying the parts takes a long time and the efficiency is low; the existing plastic spraying equipment only grinds the parts once, and the grinding effect is not good; the existing plastic spraying equipment is coated by standing and falling off the paint particles The coating particles on the surface will have insufficient adsorption force, which will lead to uneven coating thickness and affect the quality of spraying.
