Description
Technical Field
[0001] The utility model relates to the technical field of plastic film stretching, in particular to a plastic film stretching device. Background Art
[0002] Plastic film stretching device is a device used to stretch plastic film to a certain length and width. There are several methods for stretching plastic film, the most common of which is mechanical stretching. Mechanical stretching is to introduce the plastic film into the device through a set of rollers or rolls, and control the degree of film extension by adjusting the speed and arrangement of the rollers. Other stretching methods include air flow stretching, electric field stretching, etc. Plastic film stretching devices usually require a precise control system to ensure that the film maintains stable tension and good dimensional control during the stretching process. The control system usually involves electronic sensors, computer control and feedback loops to achieve automated operation and precise control. Plastic film needs to be heat treated during the stretching process to reduce its internal stress and improve its physical properties. Heat treatment can include heat expansion, hot roller preheating, etc. Heat treatment can improve the tensile properties, transparency and flatness of the film.
[0003] The thickness of existing plastic films is mostly strictly limited during film production, so most plastic film stretching devices perform secondary processing on the curled plastic film to stretch it to the required thickness. However, since the curled film roll is stretched, the thickness stretched during stretching is fixed, making it difficult to adjust the stretched thickness. In order to solve the above problems, the inventor proposes a plastic film stretching device to solve the above problems. Utility Model Content
