Closed-type powder spraying coating system

Abstract

The invention discloses a closed-type powder spraying coating system. The closed-type powder spraying coating system comprises a powder supplying system, a spraying room, a recovery device and a micropowder collecting device, wherein the powder supplying system is used for supplying coating powder; the spraying room is in butting joint with the powder supplying system; the recovery device is in butting joint with the spraying room and the powder supplying system and used for collecting redundant powder in the spraying room, separating the powder capable of being reused and conveying the powder to the powder supplying system; and the micro powder collecting device is in butting joint with the recovery device. The powder supplying system is provided with a first powder box, the first powderbox is of a closed-type box body structure, and the first powder box is internally provided with a powder feeding pipe, a powder supplying pipe and a powder return pipe, wherein the powder feeding pipe extends to the exterior of the first powder box and is connected with a powder pump and used for supplementing the powder to the interior of the first powder box; the powder supplying pipe communicates with the spraying room and used for providing the coating powder; and the powder return pipe is connected with the recovery device. According to the closed-type powder spraying coating system, the powder is supplied by adopting a closed mode, pollution of the powder to a spraying and coating workshop is reduced, and the waste powder rate is decreased.

Description

technical field [0001] The invention relates to powder spraying coating equipment, in particular to a closed powder spraying coating system. Background technique [0002] Powder spraying refers to a coating process that uses corona discharge to make powder coatings adhere to workpieces. After spraying the powder, it will form a coating film on the surface of the workpiece through steps such as hot melting and curing. [0003] The powder spraying system generally consists of a powder supply system, a spray booth, and a powder recovery system. In the existing powder spraying system, when spraying powders of different colors, it is necessary to manually use an air gun to clean up the powder left over from the previous spraying process, and then re- Add new powder. At the same time, the powder supply system in the existing powder spraying system directly pours the bagged powder into a powder box with an upper opening, and then extracts the powder from the powder box through a ...

AI Technical Summary

Problems solved by technology

[0004] 1. During the process of spraying or color changing, the powder spills into the workshop and pollutes the environment;

[0005] 2. There is a lot of powder waste during the color change process;

[0006] 3. The color change requires manual cleaning, the steps are cumbersome, and the color change takes a long time to reduce the production efficiency of the factory
