AI Technical Summary
Existing cold laminating film coating devices tend to accumulate glue at the scraper, causing production delays, poor coating effect, inconsistent glue layer thickness, and easy glue overflow. Furthermore, they are not suitable for pressing down from both sides, which affects the quality of the cold laminating film.
By adjusting the dimensions of the scraper and roller, the cylinder drives the rotating section and the annular airbag to expand and form a suitable frustum-shaped roller. Combined with the motor-driven wiping pad to clean the solidified adhesive on the scraper surface, the use of an elastic ring to enhance the extrusion effect, and the cleaning plate to clean the roller surface, uniform coating of adhesive and prevention of adhesive overflow are achieved.
It effectively prevents adhesive overflow, ensures consistent adhesive layer thickness, avoids adhesive layers sticking together due to temperature changes, and improves the production quality and efficiency of cold lamination film.
