Description

Technical Field

[0001] This utility model belongs to the field of sheet coating technology, specifically relating to a hot-pressing bonding structure and a sheet coating machine. Background Technology

[0002] In the field of sheet metal processing, sheet coating is an important process that can improve the appearance and protective properties of sheets. However, traditional sheet coating and processing equipment suffers from numerous problems during operation, affecting production efficiency, product quality, and the convenience and safety of operation.

[0003] In existing sheet lamination equipment, the film lamination process often requires extensive manual operation to adjust the lamination pressure and position. This is not only inefficient but also makes it difficult to ensure uniformity and accuracy, easily leading to film waste. For example, during hot-press lamination, it is difficult for manual operators to precisely control the pressure and relative position between the hot-press roller and the sheet, resulting in inconsistent film lamination effects. Some areas may not be firmly bonded, while others may have wrinkles, bubbles, or other problems, increasing the defect rate and causing material waste.

[0004] In view of this, we propose a hot-pressing bonding structure and a board laminating machine to solve the above problems. Utility Model Content
