AI Technical Summary

Technical Problem

Existing double-sided tape products are prone to material shortages during the die-cutting process, resulting in a high scrap rate for finished products, especially in the processing of small-sized parts.

Method used

The process employs multiple die-cutting and composite structural layers, with multiple feeding and receiving components working together to precisely control the cutting and waste disposal of the double-sided tape. This includes the design of the cutting edge of the multiple die-cutting components to ensure the precise formation of narrow adhesive strips.

Benefits of technology

It significantly reduced the defect rate of finished products to within 3%, reduced scrap due to material shortages, and improved processing accuracy and finished product quality.

Abstract

The application relates to the die cutting technical field, in particular to a processing method of double-sided adhesive product with narrow adhesive tape. In the direction of the material tape, a first feeding assembly sends out a handle release film, a second feeding assembly sends out double-sided adhesive and auxiliary material protective film, a first collecting assembly collects the raw paper in the double-sided adhesive, a third feeding assembly sends out the first auxiliary material release film, and a first die cutting assembly is used for carrying out first die cutting treatment; a second collecting assembly collects the first auxiliary release film and collects waste adhesive generated by the first die cutting treatment, a fourth feeding assembly sends out the second auxiliary material release film, and a second die cutting assembly is used for carrying out second die cutting treatment; a third collecting assembly collects the second auxiliary material release film, a fifth feeding mechanism sends out the first sealing box adhesive tape, a fourth collecting assembly collects the first sealing box adhesive tape and waste adhesive generated by the second die cutting treatment; a sixth feeding assembly sends out the third auxiliary material release film, and a third die cutting assembly is used for carrying out third die cutting treatment, and a post-processing completes the processing process.
