Description

Technical Field

[0001] The utility model relates to the technical field of color-changing film processing, in particular to a slitting device for producing automobile color-changing films. Background Art

[0002] As people's living standards continue to improve, more and more people buy cars. In order to maintain the car, they usually maintain it by spraying paint, which increases the price of car maintenance for paint surface care. At this time, most people choose a color-changing film with optional colors attached to the original paint; since a car has a long service life, the weather resistance of the color-changing film is also a very important parameter. Color-changing films with long-lasting weather resistance are also a more popular type in the industry. At present, the production process of long-weather-resistant car color-changing films is generally mixing, pressing, cooling and curing, slitting and quality inspection. Among them, the slitting process is to divide the color-changing film into a certain size of color-changing film to facilitate the fitting of the car. Since the width of the color-changing film has been determined according to demand during the cooling and curing process, only the length of the color-changing film is cut during the slitting.

[0003] Currently, the common slitting device generally uses a clamping roller to transport the color-changing film to the inside of the cutting box for cutting. For example, the comparative document with the authorization announcement number of "CN222115268U" mainly relies on the rotation speed of the clamping roller. Since the rotation speed of the clamping roller is limited, the conveying speed of the color-changing film has certain limitations, which affects the slitting efficiency of the color-changing film.
