Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing equipment, in particular to a painting device for sheet metal processing that avoids paint leakage. Background Technique

[0002] Sheet metal processing is a processing method that processes thin sheet metals through processes such as cutting, bending, stamping, and welding to produce various parts or products. These metal plates usually have a relatively thin thickness, typically between a few millimeters and dozens of millimeters, so they are called sheet metal. Sheet metal processing is very common in the manufacturing industry and is widely used, involving various fields such as automobiles, electronic devices, household appliances, and construction. During the sheet metal processing, it is necessary to paint it, which can effectively protect the surface of the sheet metal products, extend their service life, and reduce maintenance costs.

[0003] Currently, when using the painting device, the sheet metal is usually placed on the processing table, and then the operator manually uses a paint spray gun to spray on the surface of the sheet metal. This processing method makes it difficult to operate when turning the sheet metal over for painting. At the same time, paint leakage will occur during painting, polluting the working environment and requiring manual cleaning later, which is time-consuming and laborious, and the work efficiency is relatively low.
