Powder-spraying chamber for electrostatic powder spray coated

Abstract

The invention is concerned with the spray powder chamber of static powder spray coating equipment, consists of the top wall, the sidewall and the bottom wall, the top wall and the side wall is made of insulating material, the bottom wall is made of the metal material. The invention can: reduce the powder sediment, not be easy to be damaged, be easy to clean, the top wall and the sidewall is made of hollow interlayer plastic that can reduce the cost and the weight, uses round angle between the top wall and the sidewall that the powder is not easy to sediment at the corner.

Description

1. Technical field: [0001] The invention relates to a powder spraying chamber of an electrostatic powder spraying equipment 2. Background technology: [0002] The inner cavity of the powder spraying chamber of the electrostatic powder spraying equipment is generally composed of the upper top wall and side wall and the lower bottom wall. By letting the workpiece to be sprayed pass through the cavity of the spraying chamber along a predetermined path, the spray gun is used for spraying. In order to be able to effectively bond the powder to the workpiece, a high voltage electrostatic field can be generated around the spray gun by means of suitable electrodes powered by a high voltage electrostatic generator. In this way, the sprayed particles sprayed by the spray gun carry high-voltage static electricity, and the charged powder flies to the workpiece along the direction of the electric force line under the action of the electrostatic electric field force and is adsorbed on the...

AI Technical Summary

Problems solved by technology

[0003] The existing powder spraying booths are all made of metal materials. The advantage is that they are relatively strong. Even if the workpiece falls on the bottom wall of the powder spraying booth, the bottom wall will not be damaged. The disadvantages are: heavy weight, difficult handling, and high cost. High, and because the metal powder spraying room will absorb more electrostatic powder, resulting in a decrease in the powder coating rate of the workpiece, and at the same time making the cleaning work time-consuming and laborious

The disadvantage is that the strength of the plastic is poor. When the workpiece falls due to accident, it is very easy to damage the spray booth, and it is not resistant to the wear caused by trampling during manual cleaning.
