Double-sided adhesive product anti-adhesive waste discharge production process

Abstract

The disclosure provides a double-sided adhesive product anti-adhesive waste discharge production process, including the following steps: Die-cut the weak mucous membrane inner hole material consistent with the inner hole shape of the product on the weak mucous membrane material belt, and then put the weak mucous membrane material belt Drain, and then attach the main material double-sided adhesive tape and the first paper material tape in sequence, and then die-cut out the inner hole waste of the first face paper, main material double-sided adhesive tape and weak mucous membrane from top to bottom, Then paste the waste tape, then discharge the waste tape, the first paper material tape and the inner hole waste, then paste the second paper material tape, die-cut out the shape of the product, and then put the second paper The material tape and the double-sided adhesive tape of the main material are discharged, and then the shape of the release film corresponding to the product is die-cut, and then the release film material tape is discharged, so that the finished product is obtained on the bottom film material tape. The weak sticky mold of the present disclosure plays the role of anti-sticking, can realize automatic production of product inner hole waste removal, improves production efficiency, product quality and yield rate, and reduces production cost.

Description

technical field [0001] The present disclosure relates to a production process of double-sided adhesive products, in particular to a production process of anti-sticking and waste discharge of double-sided adhesive products. Background technique [0002] With the rapid development of science and technology and the continuous progress of society, mechanical automation is an inevitable development trend. There are many kinds of double-sided adhesive products with excellent sealing performance, compression deformation resistance, flame retardancy and wettability, such as solvent Type adhesive tape (oil-based double-sided tape), emulsion type adhesive tape (water-based double-sided tape), hot-melt adhesive tape, calendered adhesive tape, reactive adhesive tape, foam tape, etc., double-sided adhesive The products have been widely used in electronic products, mechanical parts, various small household appliances, mobile phone accessories, industrial instruments, auto parts, toys, cos...

Problems solved by technology

[0003] At present, double-sided adhesive products are usually processed by die-cutting. The double-sided adhesive tape is attached to the release film tape, and the corresponding products are die-cut from the double-sided adhesive tape through die-cutting equipment. For double-sided adhesive products, due to the strong viscosity, strong fluidity, and easy overflow of double-sided adhesive, the double-sided adhesive waste in the inner hole and the double-sided adhesive tape have been disconnected after die-cutting, and the double-sided adhesive waste in the inner hole is It is a separate part, and the double-sided adhesive waste in the inner hole is still bonded too strongly to the release film, so it is very difficult to discharge the waste. The existing equipment cannot automatically discharge the waste, and the waste is manually discharged.

However, the manual waste discharge method is inconvenient to operate, extremely low in efficiency, consumes more manpower, has high labor intensity, and is easy to cause damage to the product, etc. The yield rate of the product is low and the production cost is high, which affects the application and development of the product.
