Description

Technical Field

[0001] The utility model relates to the technical field of cover film processing equipment, in particular to a calendering mechanism for an easy-tear cover film. Background Art

[0002] Easy-opening film is mainly used for packaging snacks and other related leisure foods. It is a type of functional packaging material developed in response to the requirement of convenient use. According to people's traditional concept, the requirement for packaging is to be as strong as possible. It is believed that the stronger the packaging is, the better the protection effect on the goods is, so it is more desirable. However, with the development of society, especially in recent years, due to the arrival of an aging society, there has been a strong demand for easy opening. The previous concept of one-sidedly emphasizing the protection of packaging on goods and sacrificing the opening of the packaging has been greatly impacted.

[0003] The utility model with the prior art publication number CN205311011U relates to a calendering mechanism for graphite film, including an upper roller, a lower roller and a carrier film, the carrier film to be delivered is located between the upper roller and the lower roller, and a double-sided adhesive layer area is adhered to the upper surface of the carrier film; a graphite film is located on the upper surface of the carrier film and the front end of the graphite film covers the double-sided adhesive layer area, a covering film is placed on the surface opposite to the carrier film, and the covering film is located between the upper roller and the graphite film. The utility model is used for the calendering mechanism of the graphite film to effectively prevent the graphite film from wrinkling due to the relative sliding of the graphite film and the carrier film, so that it can be completely and tightly adhered to the heat-generating electronic components when it is put into use later, with better heat conduction effect and easy operation.

[0004] However, the above-mentioned calendering mechanism still has the following problems when in use: first, the calendering mechanism adopts a single-stage calendering structure design. When the easy-tear type cover film is pressed, the single calendering of the easy-tear type cover film is very likely to cause excessive stretching and damage to the film body. At the same time, when the overall calendering mechanism is assembled, installed and disassembled, its coordinated installation method is relatively simple. Utility Model Content
