Device allowing roller press to be coated with pressed film

Abstract

The invention discloses a device allowing a roller press to be coated with a pressed film. The device comprises a roller press, a first fixing part, a second fixing part and a pressed film, wherein the external surface of the roller press is coated with the pressed film; a first groove and a second groove which are adjacent are formed in the external surface of the roller press; the first fixing part is mounted in the first groove; the second fixing part is mounted in the second groove; one end of the pressed film is connected with the first fixing part; the second fixing part comprises a second clamping device and a second fixing device; the second clamping device is connected with the other end of the pressed film; the second fixing device is a second hook; the second hook is mounted in the second groove; and a first hook is arranged on the second clamping device, and connected with the second hook. With the adoption of the device, the pressed film can be taken out conveniently after the roller press is heated, and bolt or roller press damage due to the fact that the pressed film is directly fixed on the roller press is avoided.

Description

technical field [0001] The present invention relates to a rolling film, and more specifically to a device for better covering the pressing film on the outer surface of the rolling roll. Background technique [0002] The concave-convex shape on the light guide plate can be engraved on the light guide plate by rolling the concave-convex shape on the pressure film. [0003] This method of processing the light guide plate can enable the light guide plate to be processed continuously. Since the laminate is subject to wear, the laminate needs to be easily replaceable. [0004] However, this processing method is generally carried out at a high temperature after the roller is heated, and a certain pressure is applied to the roller, which will change the tension of the pressure film covering the outer surface of the roller. , to cause shrinkage or elongation of the pressure film. In order to reduce this change, it is necessary to increase the tension of the pressing film. [0005...

AI Technical Summary

Problems solved by technology

[0006] Due to the small size of the bolts fixing the film and the high tension of the film, the bolts are easy to bend and break, and even the roller is damaged due to the damage of the bolts.

[0007] Whether it is the damage of bolts or rollers, it will affect the smooth progress of production

[0008] In addition, the tension is generally adjusted when the roller is in a cooling state, but because the roller must be heated, and the tension of the laminated film will change after heating, the existing technology cannot adjust the tension of the laminated film at high temperature. In this way, it is easy to reduce the quality of the light guide plate being printed
