Problems solved by technology

[0015] First, when the operator fixes the reflective film on the above-mentioned frame, there will be problems such as fine wrinkles caused by uneven tension in the specific area of ​​the reflective film, which will lead to problems such as low image quality in the use of the rear head TV, especially Yes, when the operator manually adjusts the film, the tension in the overall area of ​​the reflective film will be uneven, which will inevitably lead to the appearance of wrinkles
[0016] Second, in order to adjust the tension of the reflective film according to a certain standard, the operator needs to invest a lot of energy

Abstract

The present invention relates to a heat treatment equipment of reflection film. Said heat treatment equipment is formed from several conveying rollers which are used for regulating tension of reflection film fixed on the defined frame and conveying the film placed on it, and are formed along conveying direction of the above-mentioned film and several heating components which are used for heating film in the course of conveying film by means of conveying rollers and are mutually spaced. The heat treatment method of the reflection film is characterized by that it includes the following systems: moving reflection mirror by means of conveying roller, in the conveying process repeatedly heating and cooling.

Description

technical field [0001] The present invention relates to a reflective film heat treatment device and method, further, in order to uniformly maintain the overall tension of the reflective film of a rear-projection TV mirror, the reflective film heat treatment device and method are heat-treated at an appropriate temperature. Background technique [0002] In order to reduce its size, the rear projection TV is equipped with a reflector between the projection light source and the screen. The projection light can display a larger image on the screen through the reflection of the reflector, so that users can watch it at a distance. to the portrait. [0003] Reflectors are divided into two types: reflectors made of glass, reflective film that can maintain flatness, and film reflectors that are fixed on the frame. [0004] Although mirrors made of glass are superior in flatness and durability, they are hardly used due to the unique disadvantages of glass, such as heavy, easy to break...
