Mixed carton batches and misprinted barcodes cause massive product recalls for pharmaceutical, food and cosmetic packaging factories. Manual sampling cannot achieve full 100% inspection on high-speed folding gluing lines.KQ-TM1 barcode detector is a dedicated inline code reading sensor designed for post-press carton production. It stably decodes standard 1D barcodes at line speeds up to 300m/min, verifying barcode existence, completeness and correctness for each passing carton. Once detecting missing, blurred or mismatched codes, the system sends instant rejection signals to the ejector to isolate defective goods automatically.Compact body structure allows quick retrofit on all mainstream folder gluers without major line modification. The sensor adapts to coated, laminated and matte paper surfaces, resisting interference from printing ink reflection and carton dust. Simple touchscreen calibration shortens product changeover time for multi-specification orders.This barcode detection unit eliminates cross-product mixing risks, fully complying with traceability standards for regulated packaging sectors.
