Automatic powder spraying device high in spraying efficiency

Abstract

The invention discloses an automatic powder spraying device high in spraying efficiency. The automatic powder spraying device comprises a powder spraying box, a first powder box, a second powder box,a plurality of static powder spraying guns, powder spraying gun swing devices, a conveying rail, a plurality of spraying part hooks, a conveying rail protection shell and a powder conveying hose. A spraying cavity is formed in the powder spraying box. According to the automatic powder spraying device high in spraying efficiency, the powder spraying gun swing devices are arranged, the powder spraying guns are arranged on the powder spraying gun swing devices, the powder spraying gun swing devices can drive the powder spraying guns to do reciprocating rotating spraying around the surface of a workpiece, and the workpiece powder spraying efficiency and the spraying quality can be improved; and spraying is more even, even spraying can be carried out on the upper face and the lower face of theworkpiece, and powder waste is reduced; two lines are arranged back to back through a powder spraying room, part of drying ovens are public, and by means of the multi-layer layout design that the workpiece is hung on the bottom floor for spraying and pretreatment and drying are carried out on the second floor, the space is saved to the maximum extent, and the requirement of the production capacityis met; and the two lines share part of facilities, and energy consumption and the labor cost are reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of spraying equipment, in particular to the technical field of powder automatic spraying equipment. 【Background technique】 [0002] Powder spraying is to use powder spraying equipment to spray powder coating on the surface of the workpiece. Under the action of static electricity, the powder will be evenly adsorbed on the surface of the workpiece to form a powdery coating; The final coating with different effects; the spraying effect of powder spraying is superior to the spraying process in terms of mechanical strength, adhesion, corrosion resistance, aging resistance, etc., and the cost is also lower than that of spraying with the same effect, but the existing spraying methods are mostly Manual spraying, the efficiency of manual spraying is low, the spraying is uneven, the workers are easy to inhale the paint during the spraying process, and many people are injured. There are some automatic powder spraying...

Problems solved by technology

[0002] Powder spraying is to use powder spraying equipment to spray powder coating on the surface of the workpiece. Under the action of static electricity, the powder will be evenly adsorbed on the surface of the workpiece to form a powdery coating; The final coating with different effects; the spraying effect of powder spraying is superior to the spraying process in terms of mechanical strength, adhesion, corrosion resistance, aging resistance, etc., and the cost is also lower than that of spraying with the same effect, but the existing spraying methods are mostly Manual spraying, the efficiency of manual spraying is low, the spraying is uneven, the workers are easy to inhale the paint during the spraying process, and many people are injured. There are some automatic powder spraying equipment in the existing technology, but the spray guns of the existing automatic powder spraying equipment are mostly installed in the powder room Both sides can only move up and down, and the upper and lower end surfaces of the workpiece may not be sprayed, resulting in uneven spraying and affecting the quality of the finished product
