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.
