Powder recovery structure of electrostatic spraying chamber

Abstract

The invention discloses a powder recovery structure of an electrostatic spraying chamber. The powder recovery structure comprises a spraying box and a spraying gun, and further comprises a workbench, an enclosure bulkhead, a powder collecting assembly and a vibration assembly; the workbench is arranged on the bottom wall in the spraying box, and sliding grooves are formed in the side faces of the left side and the right side of the workbench; the powder collecting assembly comprises a cleaning roller, a driving screw rod, a motor and collecting boxes; the cleaning roller is in sliding fit on the workbench in the left-right direction of the workbench; the motor is mounted on the outer side wall of the spraying box and connected with the end of the cleaning roller through the driving screw rod; the two collecting boxes are in sliding fit in the sliding grooves in the left side and the right side of the workbench correspondingly; the enclosure bulkhead is provided with an upper opening and a lower opening, and the caliber of the upper opening is larger than that of the lower opening; and the vibration assembly is mounted on the side wall of the spraying box and can knock the enclosure bulkhead. According to the powder recovery structure, most of powder which is not coated on a product can be collected, and collecting is convenient.

Description

technical field [0001] The invention relates to the field of electrostatic spraying, in particular to a powder recovery structure of an electrostatic spraying room. Background technique [0002] The working principle of the electrostatic powder spraying method is almost the same as that of the general liquid paint electrostatic spraying method, the difference is that the powder spraying is dispersed rather than atomized. It is a coating sprayed by an electrostatic powder spray gun. While dispersing, the powder particles are negatively charged. The charged powder particles are subjected to other forces such as airflow or centrifugal force and electrostatic attraction, and are applied to the grounded object to be coated. , and then heated to melt and solidify into a film. Electrostatic powder spraying method is the dominant powder coating method in the field of industrial coating. [0003] During the electrostatic spraying process, there will be a lot of powder that is not s...

Problems solved by technology

However, it is extremely inconvenient to recover the powder falling on the bottom wall or side wall of the spray booth, which leads to a large amount of powder that cannot be recycled, and the powder remaining in the spray booth will also pollute the inner space of the spray booth

Therefore, there is room for improvement in the powder recovery structure of the spray booth in the prior art
