Drying system for drying color changing film through hot air

Abstract

The invention provides a drying system for drying color changing film through hot air. The drying system comprises a workbench, a drying box is fixedly installed at the top of the workbench, a film inlet and a film outlet are formed in the side walls of the two sides of the drying box respectively, supports are fixedly installed on the two sides of the bottom in the drying box respectively, a guide roller is rotationally connected to each support, the guide rollers are arranged on one side of the film inlet and one side of the film outlet correspondingly, and a temperature and humidity sensor is fixedly installed on the inner side wall of the drying box. By arranging a leveling and water absorbing assembly, after the color changing film enters the drying box, two sets of leveling rollers of the leveling and water absorbing assembly rotate to roll and level the color changing film, the quality of the color changing film is improved, bulging and folding of the color changing film are avoided, and the flatness of the color changing film is guaranteed; and meanwhile, when the two groups of leveling rollers are used for rolling and leveling the color changing film, water absorption sponge is used for adsorbing water generated by evaporation of the color changing film, so that the color changing film can be dried more quickly.

Description

[0001] The invention relates to the technical field of color-changing film processing, in particular to a drying system for drying the color-changing film with hot air. Background technique [0002] With the continuous improvement of people's living standards, more and more people are buying cars. In order to maintain the car, it is generally maintained by spraying paint, which increases the price of car maintenance for a lot of paint care. At this time, most of them choose a car in the original A color-changing film of optional color is attached to the paint. During the production process of the color-changing film, the non-silicon release film needs to be scraped or sprayed on the surface of the non-silicon release film through a scraper or a gap coating head, and then Then go through oven drying. [0003] However, there are certain defects in the existing drying system used in the production process of the color changing film. The existing drying system mostly adopts electr...

Problems solved by technology

[0003] However, there are certain defects in the drying system used in the production process of the existing color-changing film. The existing drying system mostly uses electric heating to dry. Drying makes the moisture in the color-changing film material evaporate, but when the evaporated water vapor permeates the entire oven of the dryer, it may cause the oven to be damp, and cause short-circuit damage to electrical components, resulting in additional maintenance costs; and When there is a large amount of water vapor in the oven, the drying effect of the color changing film is reduced due to the increase of the humidity in the oven, resulting in a decrease in the quality of the color changing film. The hot air blowing out of the traditional drying system is not uniform enough, and the drying efficiency of the color changing film is low.
