Paint charging and discharging system used for vamp painting

Abstract

The invention discloses a paint charging and discharging system used for vamp painting. The paint charging and discharging system comprises a paint spraying container, a paint supplying container, a paint receiving container and a paint injecting container, wherein a paint inlet pipeline and a paint returning pipeline are arranged between the paint spraying container and the paint supplying container; a pump is arranged in the paint supplying container; the paint inlet pipeline is connected with the pump through a pipeline; a paint discharging pipeline is arranged between the paint receiving container and the paint supplying container; the highest spot of the pipeline of the paint discharging pipeline is higher than the topmost end of the pump in the paint supplying container; a paint injecting pipeline is arranged between the paint injecting container and the paint supplying container; and the pipelines of the paint inlet pipeline, the paint returning pipeline, the paint injecting pipeline and the paint discharging pipeline are separately provided with a stop valve. According to the paint charging and discharging system, by reasonably arranging the paint discharging pipeline, dryoperation of the pump caused by the fact that paint discharging speed is higher than paint injecting speed can be avoided; and meanwhile, vamp painting disqualification caused by the fact that the paint spraying container cannot get enough paint is also avoided.

Description

technical field [0001] The invention relates to shoe upper processing technology, in particular to a paint adding and discharging system for shoe upper painting. Background technique [0002] In the painting process of shoe uppers, the painting container and paint are indispensable. The painting process of shoe uppers is completed in the painting container, and in the whole process, it is necessary to continuously replenish the paint to the painting container through the paint supply container, and the power device for replenishing the paint For the pump in the paint supply container, in the prior art, it often occurs that the pump runs dry due to the unreasonable paint discharge structure of the paint supply container when replenishing paint. On the one hand, it is easy to cause damage to the pump, on the other hand, it will cause the paint spray container Insufficient paint can affect the quality of shoe upper painting, resulting in unqualified shoe upper painting and rewo...

AI Technical Summary

Problems solved by technology

[0003] The problem to be solved by the present invention is to overcome the problem in the prior art that the pump is empty and dry due to excessive paint discharge caused by the unreasonable paint discharge pipeline of the paint supply container, and at the same time the problem that the paint spray container cannot get enough paint. Use the additional paint discharge system, which can avoid excessive discharge of paint from the paint supply container during the shoe upper painting process by setting a reasonable pipeline structure
