A protective device for pretreatment of acid-resistant substance coating on single-sided galvanized steel sheet

Abstract

The invention relates to an acid-proof substance coating protection device used for pretreatment of a single-sided galvanized steel sheet. The acid-proof substance coating protection device used for pretreatment of the single-sided galvanized steel sheet comprises a mounting frame of a U-shaped structure. Conveying support rollers are evenly arranged on the inner wall of the mounting frame from front to back. Adjustment executing grooves are symmetrically formed in the left side and the right side of the mounting frame. Adjustment executing mechanisms are arranged in the adjustment executing grooves. Two fixing grooves are formed in the mounting frame. By adoption of the acid-proof substance coating protection device used for pretreatment of the single-sided galvanized steel sheet, the problems that in the prior art, the to-be-galvanized end face of a single-sided galvanized steel sheet needs to be manually protected in the pretreatment process for galvanization of the steel sheet, manual protection of the steel sheet is inaccurate, the probability that the to-be-galvanized end face of the steel sheet is affected by acid-proof substances due to misoperation on the to-be-galvanizedend face of the steel sheet cannot be avoided, normal galvanization cannot be conducted, and redundant acid-proof substances on the surface of the steel sheet need to be manually recycled are solved.

Description

technical field [0001] The invention relates to the technical field of galvanized steel sheets, in particular to a protection device for pretreatment of single-sided galvanized steel sheets coated with acid-resistant substances. Background technique [0002] Single-sided galvanized steel sheet is galvanized on only one side of the steel sheet. The single-sided galvanized steel sheet needs to be pre-treated before galvanizing. The surface of the steel sheet that does not need to be galvanized is coated with an acid-resistant substance. However, the existing single-sided galvanized In the pre-galvanizing process of the steel plate, it is necessary to manually protect the end face of the steel plate that needs to be galvanized. The manual protection of the steel plate is not accurate, and it is impossible to ensure that the end face of the steel plate that needs to be galvanized will not cause acid-resistant substances to the steel plate that need to be galvanized due to operati...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a single-sided galvanized steel sheet pretreatment acid-resistant material coating protection device, which can solve the existing single-sided galvanized steel sheet in the pre-galvanizing process that requires manual galvanizing of the steel sheet The end face of the operation is protected, and the manual protection of the steel plate is not accurate, and it is impossible to ensure that the end face of the steel plate that needs to be galvanized will not cause the acid-resistant substance to affect the end face of the steel plate that needs to be galvanized due to operational errors, and the normal galvanizing operation cannot be performed. Recycling of excess acid-resistant substances on the surface requires complicated operations, high labor intensity and low work efficiency. It can realize the precise protection function of acid-resistant substances coated on one-sided galvanized steel sheets, and will not affect the single-sided galvanized operation of steel sheets. Steel plate for precise protection, and has the advantages of simple operation, low labor intensity and high work efficiency
