Light guide film anti-warping production leveling device

Abstract

The invention provides a light guide film anti-warping production leveling device. The device comprises a fixed support mechanism, a sliding support mechanism and a tension detection mechanism, wherein the fixed support mechanism, the sliding support mechanism and the tension detection mechanism are oppositely arranged, the tension detection mechanism is arranged on the surface of a light guide film, and the fixed support mechanism is provided with a driving mechanism for driving the sliding support mechanism to slide. According to the device, the sliding support mechanism is driven to slide through the driving mechanism mounted on the fixed support mechanism, furthermore, the sliding support mechanism drives a guide shaft to move relative to a rolling shaft, in addition, tension detectionis carried out on the light guide film through the tension detection mechanism, so that the surface tension of the light guide film is in a reasonable range, the light guide film is horizontally detected precisely through cooperation of an infrared signal emitter and an infrared signal receiver, the height of the guide shaft is adjusted through a lifting assembly, so that the light guide film isguaranteed to be in a horizontal state, the phenomenon that the light guide film is damaged and warped is prevented, the quality of the light guide film is ensured, the structural design is reasonableand simple, and the use is convenient.

Description

technical field [0001] The invention relates to the field of light guide films, in particular to a production leveling device for preventing warping of light guide films. Background technique [0002] The dots of the light guide film are generally processed on the light guide plate by injection molding, hot pressing or printing. However, it is difficult to realize the thin film design of the light guide plate by traditional injection molding and injection molding. The current method of preparing the light guide film is gradually tending to integration Design, one-step molding, simplifies the production process of the light guide film and saves costs, so extrusion molding is the preferred way to prepare the light guide film. [0003] Chinese invention patent CN207224639U discloses a light guide film production equipment, including feed inlet, melting and stirring zone, stirring blade, punching head, first polygonal rolling shaft, controller, guide wheel, second polygonal roll...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a production leveling device for anti-warping of the light guide film, which solves the problem that the sliding grinding block is not stable due to the insufficient level of the light guide film when the light guide film is converted from a vertical state to a horizontal state during the transmission process. The light guide film is damaged and warped, or the surface tension of the light guide film changes, which can easily cause the light guide film to be damaged and warped, which greatly reduces the quality of the light guide film.
