Problems solved by technology

However, when the existing spraying equipment is spraying different colors of paint, the color changing process is complicated, and there are many powder residues in the pipeline, which are easy to mix colors and affect the spraying quality. Therefore, it is necessary to design an efficient and thorough color changing powder supply system

Abstract

The invention discloses a powder feeding center of spraying equipment, which comprises a powder recovery opening, a powder pump, a power recovery pipe, a powder feeding pipe, a reverse suction pump and a powder container, wherein the powder pump is communicated with the powder recovery opening and is used for feeding coating entering the powder recovery opening into the power recovery pipe; the powder feeding pipe is communicated with a spray gun; the powder recovery pipe and the powder feeding pipe are connected with the reverse suction pump and communicated with the powder container; and the reverse suction pump is used for sucking in airflow to suck powder in the powder recovery pipe and the powder feeding pipe into the powder container when color change is needed. The structure of the powder feeding center is optimized, a sensor is arranged to facilitate material depth measurement, a slidable bracket is arranged to enable the powder recovery pipe and the powder feeding pipe to suck in powder in real time, no manual adjustment is needed, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the field of metal sheet metal surface treatment, in particular to a powder supply center for spraying equipment. Background technique [0002] The electrostatic powder spraying process appeared in the 1960s and was mainly applied to metal surface coating. With the rapid development of my country's manufacturing industry, due to the unique advantages of powder spraying technology, such as good environmental performance, simple operation, no organic solvent, and excellent coating performance, the proportion of metal surface treatment continues to increase year by year. It has mostly replaced the original paint coating process. Similar to the painting process, the powder spraying process also places the workpiece in a semi-enclosed space (that is, the spray booth) to prevent the powder that is not on the workpiece from spreading around; but unlike the paint process, it can be effectively carried out in this spray room. Powder re...
