Description

Technical Field

[0001] The utility model relates to the technical field of plastic agricultural films, and specifically relates to a device for detecting the light transmittance of plastic agricultural films. Background Art

[0002] Agricultural films are products used in agricultural production to protect plants from water loss and other measures. With the progress of science and technology, the requirements for agricultural films are getting higher and higher, and various new types of films are constantly emerging. In the production of agricultural films, after the film is formed, it is wound into a roll through mechanical processing. Generally, when sampling and detecting the cost and quality, a light transmittance detector is held in hand to directly detect the light transmittance of the ground film.

[0003] For example, in the "Device for Detecting the Light Transmittance of Plastic Agricultural Films" with the Chinese patent publication number CN218157542U, this utility model relates to a device for detecting the light transmittance of plastic agricultural films, including a base. A lifting component is arranged on the top of the base, a frame structure is arranged on the lifting component, two roller wheels are rotatably connected inside the frame structure, and a photoelectric illuminometer is arranged on the frame structure. For this device for detecting the light transmittance of plastic agricultural films, the film is inserted between the lighting lamp and the roller wheels and attached to the two roller wheels. Then, the height of the frame structure is adjusted through the lifting component to stretch the film by the roller wheels, making the film flat on the two roller wheels, which is convenient for flat detection and improves the accuracy of light transmittance detection. By moving the base to the position of the film before winding, the film is directly inserted between them, the film is located on top of the two roller wheels, stretched and flattened, and then irradiated by the lighting lamp. The photoelectric illuminometer detects the light transmittance below the film, so as to perform real-time detection before winding. The operation is convenient and it is easy to be installed in the winding machine.

[0004] However, in actual use, when it is necessary to adjust the film to make it flat, it is necessary to adjust the height of the frame structure through the lifting component to stretch the film by the roller wheels, making the film flat on the two roller wheels. The operation is complex and it is not convenient to quickly stretch and flatten the film. Content of the Utility Model
