The Application of Portable Devices on Yarn Quality Inspection

In recent years, with the development of the yarn quality testing technology, it can not only save a lot of work force, but also can improve the quality of products. Because the traditional detection device has many limitations, this project uses optical detection technology and intelligent laser sensors. We develop a portable online testing and self-leveling device that can detect the quality of fibers in the workshop at any time and show a variety of curves and data. It can also be printed at all times. Based on detection, the project realizes the cotton carding, and comb since adjusted motion, and through the PLC program achieves more line approximation polynomial curve.
