AI Technical Summary

Technical Problem

Traditional metal sheet spraying equipment is inefficient, produces uneven spraying quality, has long drying time and inconsistent results, and cannot meet the needs of diverse products.

Method used

The system employs an adjustable cylinder linked to a buffer spring to achieve precise centering of the thin sheet, a hydraulic rod in conjunction with a positioning plate for stable clamping, and a spray head that moves in three dimensions via vertical and horizontal slide rails. Combined with a warm air accelerator fan and a convection heating layer, it forms a hot air circulation, and a lifting baffle enables independent drying of each thin sheet.

Benefits of technology

It improves the quality and efficiency of spraying, ensures coating uniformity and adhesion, shortens drying time, reduces energy consumption, and enhances the protective and decorative properties of thin metal sheets.

Abstract

This utility model relates to the field of metal sheet processing technology and discloses a rapid spray coating and drying device for metal sheet surfaces. It includes a spray mounting base, with two sets of protective railings fixedly installed on the outer wall of the base in a symmetrical arrangement. The base is U-shaped, and a control display box is fixedly installed on the outer wall of the protective railings. By incorporating a warm air accelerator fan and a convection heating layer to form a hot air circulation system, the thin sheet is heated evenly on both sides, shortening the drying time and improving efficiency compared to traditional static drying. Simultaneously, a lifting baffle allows for independent drying of individual sheets, preventing heat loss. Combined with precise temperature control using heating resistance wires, energy consumption is reduced. A breathable plate and ventilation holes accelerate moisture removal, ensuring drying quality. The adhesion of the cured coating is improved, effectively enhancing the protective and decorative properties of the metal sheet and achieving the effect of improved drying efficiency.
