Abstract
Description
Technical Field
[0001] This utility model relates to the field of stainless steel strip processing technology, specifically to a stainless steel strip coating equipment. Background Technology
[0002] Metal sheet coating technology is a processing technique that involves bonding a plastic film to a metal sheet through high-temperature hot pressing. Originating in Japan in 1977, this technology was initially used in can manufacturing, replacing internal and external coating techniques. Today, it has expanded to various fields such as building material interiors, appliance casings, and ship interiors. Because coating does not use adhesives or solvents, it is formaldehyde-free. Furthermore, the plastic film can undergo beautification, antibacterial, and anti-staining treatments, ensuring human safety and health while also contributing to environmental protection. Quality standards for coated products include: a clean, flat, and clear surface; good gloss; no wrinkles; and no bubbles. Proper drying is required, with no damage to the surface film. Accurate slitting dimensions after coating, smooth edges, and no film leakage are necessary. There should be no obvious curling or warping. During stainless steel strip processing, after the stainless steel strip is transferred or processed, a protective film needs to be applied to the surface to protect it and reduce the risk of scratches. Currently, the lamination process uses seamless tubes to support the protective film for manual lamination. However, due to the manual operation, the quality of each lamination is inconsistent, and air bubbles often appear inside the film, affecting the quality of the lamination. Manual lamination is also slow, with the steel strip speed limited to within 4m / min. There is a limit to the manual speed, and increasing the speed will not guarantee the quality of the lamination.
