Problems solved by technology

The existing electrostatic spraying equipment only sprays the parts through a single rotating part or rotating spray head, the spraying time is long and the efficiency is low; the existing electrostatic spraying equipment only grinds the parts once, and the grinding effect is not good; Some electrostatic spraying equipment controls the coating by standing and falling off the coating 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.

Abstract

The invention discloses electrostatic spraying equipment for the inner wall of a tubular electromechanical part. A powder supply device communicates with a feeding opening of a first air pipe, air supply equipment communicates with an air inlet of a second air pipe, a discharging opening of the first air pipe, an air outlet of the second air pipe and an inlet of a third air pipe communicate with one another, the third air pipe communicates with a spraying unit, a first valve is arranged on the first air pipe, a second valve is arranged on the second air pipe, a clamping unit is rotatably arranged below an L-shaped supporting frame, a control unit is arranged between the first valve and the second valve, the spraying unit is arranged below the L-shaped supporting frame in a rotatable lifting mode, and the lifting path of a spraying gun of the spraying unit can be located in the tubular part. According to the electrostatic spraying equipment for the inner wall of the tubular electromechanical part, spraying can be carried out on the inner wall of the part through the arrangement of the lifting spraying unit, the first valve and the second valve can be controlled to be opened in sequence through the arrangement of the control unit, the effects that preheating of the inner wall of the part through air spraying is carried out and then electrostatic spraying is carried out are achieved, and therefore the electrostatic spraying quality is guaranteed.

Description

technical field [0001] The invention relates to the field of electromechanical plastic spraying, in particular to an electrostatic spraying equipment for the inner wall of tubular electromechanical parts. Background technique [0002] Electrostatic spraying refers to the coating method that uses the principle of corona discharge to make the atomized paint negatively charged under the action of a high-voltage direct current electric field, and adsorbed on the surface of the positively charged substrate to discharge. Electrostatic spraying equipment consists of a spray gun, a spray cup, and a high-voltage power supply for electrostatic spraying. With the increase in demand and the increasing emphasis on environmental protection, the application range of electrostatic spraying is expanding day by day. From large railway passenger cars, automobiles, tractors, to small workpieces, toys and household appliances, etc., electrostatic spraying technology can be used. The existing el...
