The invention relates to a web quality detection system for a carding machine. The system comprises a web output device, a camera device, a light source and a detection device, wherein the camera device and the light source are both arranged above an outlet of the web output device, and a certain angle is formed between the light source and the camera device; the camera device is electrically connected with the detection device. The system also comprises a detection box body; a first channel and a second channel are arranged on the left side wall and the right side wall of the detection box respectively, and a web passes through the first channel and the second channel; a dust suction pipe is arranged at the top end of the detection box body and is connected with filter cotton through a fan; and the camera device and the light source are arranged in the detection box. A computer vision detection device is used for detecting a carding machine web and calculating the web uniformity, andthe detection result is accurate and objective. The camera device and the light source are arranged in the detection box body, so that flying and pollution of fiber dust and pollution of an external environment to the web are effectively avoided, and the final detection precision is improved.
Description
Technical field [0001] The invention belongs to the technical field of textile devices, and specifically relates to a cotton web quality detection system for a carding machine. Background technique [0002] The carding process is the main process to control and reduce neps and impurities. In the spinning process, reducing card sliver jumbles plays a decisive role in improving the uniformity of yarn evenness. Improving the working quality of carding machines and improving the quality inspection and control methods of carded semi-finished products have always been one of the focuses of people's attention. [0003] For the quality inspection of carded semi-finished products (card sliver) in the prior art, most manufacturers use traditional visual inspection methods to detect the neps content of semi-finished products and finished products in various textile processes; in recent years, with the development of computer vision technology, there are also Computer vision is applied to the...
