GJC-600 Side Seam Glue Detection System – RF Sensing for High-Speed Carton Side Seams

Keqi GJC-600 relies on radio frequency (RF water content sensing technology) to inspect cold glue on carton folding side seams, a core principle different from infrared glue detectors. Cold glue contains water molecules that change local RF signal absorption; the sensor accurately calculates glue length, width and thickness by capturing signal fluctuation, with ultra-high 1mm minimum detection resolution.

It adapts to cardboard thickness under 2mm and adhesive thickness within 1.5mm, running stably at an unprecedented maximum line speed of 600m/min, far exceeding conventional glue inspection equipment limits.

The prominent advantages of GJC-600 focus on ultra-fast detection and strong substrate adaptability for non-metallic coated cartons. The independent sensor head installs at the folder gluer folding section to monitor side seam glue before carton shaping, thoroughly preventing hidden defects like partial missing glue and edge overflow that cause finished box separation. The human-machine touch interface stores multiple product parameter presets; operators switch packaging styles with one click without repeated calibration. When glue defects appear, the system triggers linked rotary or piston ejectors to automatically separate unqualified products, achieving 100% full inline inspection without sampling.

Its core application scenarios cover straight folding cartons, medicine boxes, liquor packaging and food gift boxes that rely on side seam bonding. Many export printing factories adopt GJC-600 to meet strict foreign trade packaging quality standards, removing risks of batch returns due to degumming. The lightweight sensor structure occupies minimal conveyor space, compatible with all mainstream domestic and imported folder gluer brands. Compared with manual visual inspection, it eliminates human fatigue error and cuts inspection labor cost by over 70%, improving production line overall efficiency and finished product pass rate simultaneously.
