The automatic high‑speed rewinding‑inspection machine runs with coordinated operation of a PLC main‑control unit, vision‑detection assembly, closed‑loop tension module and automatic deviation‑correction mechanism. Raw roll‑shaped materials are unwound from an air‑expansion shaft and conveyed steadily via guide rollers. Tension sensors feed real‑time tension data, and servo motors dynamically adjust tightness to avoid stretching and wrinkles on films and non‑woven fabrics. When materials pass through the inspection station, linear‑array industrial cameras with dedicated light sources scan the web at high speed. The system compares captured pictures with standard samples to automatically spot pinholes, scratches, dark spots, folds and printing flaws while recording defect locations. It triggers marking and accurate low‑speed halt for manual defect disposal. Integrated functions including length‑counting, slitting and web‑guiding prevent material offset. Qualified materials are neatly rewound. All procedures operate synchronously under closed‑loop speed control, combining roll‑rechecking, flaw screening and finished‑product rewinding in one‑step operation.
