The electrostatic spraying device includes a machine body, a storage barrel is fixed on the machine body, a discharging hole connected with a conveying pipe is formed in a portion close to the bottom of the side wall of the storage barrel, an elastic filter net is arranged in the discharging outlet, a connectingplate is fixed on a portion, close to the discharging hole, of the inner wall of the storage barrel, a connecting rod vertically extending downward is hinged to a portion close to the middle of the connecting plate, a magnetic column is fixed at the bottom of the connecting rod, a plurality of working needles are arranged on the outer surface of the magnetic column, and both ends of the connecting plate are fixedly provided with a first electromagnet and a second electromagnet used for sucking the magnetic column; according to the electrostatic spraying device, the blockage of coating in theconveying pipe is avoided, and the continuity of transportation work is ensured, thereby improving spraying efficiency.

Description

technical field [0001] The invention relates to the field of electrostatic spraying equipment, in particular to an electrostatic spraying equipment which facilitates spraying work. Background technique [0002] Electrostatic spraying is a spraying method that uses a high-voltage electrostatic electric field to make negatively charged paint particles move in the direction opposite to the electric field, and adsorb the paint particles on the surface of the workpiece. The electrostatic spraying equipment mainly includes an electrostatic spray gun and a machine body. The original paint is filled into the electrostatic spray gun, and then the paint is sprayed on the workpiece through the electrostatic spray gun. Due to the limited size of the nozzle of the electrostatic spray gun, there are great requirements for the quality of the paint. The powder coating that has been idle for a long time is easy to contact with the air for a long time Finally, it will condense into granules. ...

[0002] Electrostatic spraying is a spraying method that uses a high-voltage electrostatic electric field to make negatively charged paint particles move in the direction opposite to the electric field, and adsorb the paint particles on the surface of the workpiece. The electrostatic spraying equipment mainly includes an electrostatic spray gun and a machine body. The original paint is filled into the electrostatic spray gun, and then the paint is sprayed on the workpiece through the electrostatic spray gun. Due to the limited size of the nozzle of the electrostatic spray gun, there are great requirements for the quality of the paint. The powder coating that has been idle for a long time is easy to contact with the air for a long time Finally, it will condense into granules. During the process of conveying these powder particles to the electrostatic spray gun, it will easily cause blockage in the conveying pipeline, which will cause incoherent spraying work of the electrostatic spray gun, and even cause interruption of the working process, affecting work efficiency.
