Double-faced adhesive tape product anti-sticking waste discharge production process

Abstract

The invention provides a double-faced adhesive tape product anti-sticking waste discharge production process. The double-faced adhesive tape product anti-sticking waste discharge production process comprises the following steps of conducting die cutting on a weak adhesive film material belt to form a weak adhesive film inner hole material in the same shape as an inner hole of a product, discharging the weak adhesive film material belt, sequentially laminating a main material double-faced adhesive tape material belt and a first surface paper material belt, performing die cutting to obtain innerhole wastes of first surface paper, a main material double-sided adhesive tape and a weak adhesive film in sequence from top to bottom, laminating a waste discharge adhesive tape, discharging the waste discharge adhesive tape, the first surface paper material belt and inner hole waste, laminating a second surface paper material belt, performing die cutting to obtain the appearance of the product,discharging the second surface paper material belt and the main material double-sided adhesive tape, then performing die cutting to form the shape of a release film corresponding to the product, discharging the release film material belt, and obtaining a finished product on a bottom supporting film material belt. A weak adhesion die has an anti-adhesion effect, automatic production of product inner hole waste removal can be achieved, the production efficiency and the product quality and yield are improved, and the production cost is reduced.

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 for 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 a variety of double-sided tape products with excellent sealing, compression deformation resistance, flame retardancy, and wettability, such as solvents. 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 tape Products have been widely used in various fields such as electronic products, mechanical parts, various small household appliances, mobile phone accessories, industrial instruments, auto parts, toys, cosmet...

AI Technical Summary

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.
