Abstract

This invention relates to the field of textile inspection technology, specifically to a defect detection device and method for chemical fiber fabrics. The device includes a detection body, a cutting body, a fixed mounting frame, a baffle adjusting roller, a first electric push rod, a lifting adjusting frame, a conveying detection frame, a flat adjustment body, and support legs. The support legs are fixedly installed at the bottom of both ends of the conveying detection frame, and the flat adjustment body is located in the middle of both sides of the conveying detection frame. This invention achieves efficient, accurate, and adaptive detection of defects in chemical fiber fabrics. The device features a bidirectional tensioning and flat adjustment body, effectively eliminating fabric wrinkles. It is equipped with a multi-detection head array (support and adjustment section and detection section) with adjustable spacing, angle, and height, and incorporates visible light, infrared, and ultraviolet multispectral light sources. This allows it to adapt to fabrics of different widths and materials, improving the capture and detection coverage of various defects, especially minute defects, resulting in efficient and accurate detection.
