Description
Technical Field
[0001] The utility model relates to the technical field of electrostatic powder spraying equipment, in particular to a lifting type electrostatic powder spraying machine. Background Art
[0002] In order to facilitate the electrostatic spraying of powder coatings, it is often necessary to use electrostatic powder spraying equipment. The utility model patent with patent application number CN201920951402.8 discloses a high-voltage electrostatic powder spraying mechanism. A butterfly valve made of ordinary metal is fixed to the fixed shaft of the butterfly plate. The high-voltage electrostatic powder spraying gun is started. The position of the high-voltage electrostatic powder spraying gun is adjusted by the horizontal drive mechanism and the vertical drive mechanism. The angle of the butterfly valve is adjusted by the first stepper motor to evenly spray the anti-corrosion material onto the butterfly plate. After the mechanism is used for spraying, the surface of the butterfly plate has anti-corrosion material, which makes the ordinary metal made butterfly plate The corrosion resistance of the butterfly plate can also meet the requirements of seawater butterfly valves, thereby greatly reducing the manufacturing cost. According to the technical solution disclosed therein, the existing electrostatic powder spraying equipment cannot effectively ensure the uniformity and stability of the electrostatic powder feeding when in use. It is easy for the powder to block the feeding and cause uneven feeding, which is not conducive to ensuring the stability of the spraying operation. On the other hand, when performing electrostatic spraying, a small amount of electrostatic powder is likely to fail to contact the electrostatic ring, resulting in no static electricity or very weak static electricity carried, which is not conducive to ensuring the adhesion of the electrostatic powder and is not conducive to ensuring the spraying quality.
