AI Technical Summary
In traditional composite film production equipment, the glue coating roller contacts the upper surface of the TPU film to apply glue, which makes it difficult to recycle excess glue, resulting in poor coating effect. Furthermore, it is difficult to ensure the tightness between the coating roller and the TPU film, causing glue to overflow and contaminate the film surface during the mold closing process.
The system employs an adhesive application assembly and an adhesive scraper assembly. The adhesive application assembly applies adhesive to the fabric adhesive cover using an arc-shaped spray plate and an adhesive roller, while the adhesive scraper assembly removes excess adhesive using a guide plate and a scraper. Combined with an adhesive pump, the adhesive can be recycled.
Ensure that the adhesive is applied sufficiently to avoid waste, achieve accurate dosage and reuse of adhesive, and prevent adhesive from contaminating the surface of the composite film.
