AI Technical Summary
In the existing technology, the adhesive on the coating roller is not evenly distributed during the coating process of self-adhesive labels, resulting in uneven coating.
A rotating mechanism drives the first and second coating rollers to rotate synchronously. The distance between the coating rollers is adjusted by a scraper. Combined with a lifting mechanism and a translation mechanism, the coating rollers can be evenly coated and excess glue can be scraped off, ensuring that the label strip adheres to the coating rollers.
This resulted in a more uniform distribution of adhesive on the coating roller, improving coating quality.
