Description

Technical Field

[0001] The utility model relates to the technical field of sunshade net light-shielding rate detection, in particular to a rapid light-shielding rate detection device. Background Technique

[0002] A sunshade net is a net-shaped material made of plastic materials such as polyethylene and polypropylene through processing and weaving. Since different application scenarios have different requirements for the light-shielding degree of the sunshade net. For example, agricultural greenhouses may require sunshade nets with specific light-shielding rates to control light and temperature to meet the growth needs of different crops; in building sunshading, it is also necessary to select sunshade nets with appropriate light-shielding rates according to the requirements of indoor lighting and heat insulation. Therefore, it is necessary to detect the light-shielding rate of the sunshade net, and thus it is necessary to use detection equipment.

[0003] When the existing detection equipment detects the sunshade net, it usually directly places it in the detection area, uses the strong light of the irradiation lamp to irradiate the sunshade net, and then uses a light intensity meter to measure the light intensity. However, since the sunshade net is relatively soft in texture, during the detection process, it is extremely easy to produce wrinkles. The existence of wrinkles will cause local protrusions on the net surface, resulting in a decrease in the light-shielding ability of this part, allowing more light to pass through, and affecting the overall light-shielding effect. In view of this problem, we propose a rapid light-shielding rate detection device. Content of the Utility Model
