Foreign particles and fiber detecting machine

详情

Brief Introduction: Before cotton fiber can be spun, the raw cotton must be sorted to remove any foreign particles and fibers. While foreign particles can be clearly distinguished from the raw cotton by color, contrast and structure, foreign fibers such as polypropylene or polyethylene films are often light and transparent, making them difficult to detect using conventional foreign particle separators. To detect these particles and separate them safely, the raw cotton is illuminated under polarized light, making the foreign fibers appear colored. In this way, they can be distinguished from the raw cotton and separated. Our machine equipped with color linear-scan camera CCD and trilinear sensor to get the cotton flow image and detect the foreign particles and fibers, then clear foreign and colour-contaminated fibers by use of detector and separator. For such applications, a trisensor camera system with a color beamsplitter is the only option to ensure the highest possible color registration. This can result in image artifacts appearing when such sensors are used in high-speed imaging application
