The YJP Series Sheet-fed Inspection Folder Gluer Machine is an innovative all-in-one post-press equipment specially developed for the sheet-fed packaging industry. It integrates high-speed folder gluing with a high-precision online inspection system, adopting an advanced dual alignment units structure with the inspection module installed between the two units to ensure stable and reliable inspection quality. This machine effectively replaces manual visual inspection, drastically reduces labor costs, improves production efficiency, and stops defective products from flowing into the market, making it the ideal choice for high-standard packaging production enterprises.
Unlike traditional folder gluers, this online inspection folder gluer features a dual alignment design, with the inspection system embedded between two positioning units to ensure sheets are fully fixed before inspection. This eliminates detection deviation from sheet shifting, reduces false and missed detection rates, and guarantees 100% full inspection of every product without slowing down production.
The machine delivers a max belt speed of 350 M/min and max inspection speed of 300 M/min, achieving synchronous high-speed folder gluing and full inspection. It helps industrial manufacturers double production efficiency compared with manual inspection lines, shorten order delivery cycles, and meet large-scale mass production demands.
Equipped with a high-resolution visual system, this packaging inspection folder gluer equipment covers full-item defect detection: printing defects, surface process defects, barcode variable information, and reverse side defects, with a minimum detection accuracy of 0.05mm×0.05mm. It fully meets the strict quality compliance requirements of pharmaceutical, tobacco and food packaging industries, helping enterprises avoid quality risks and brand reputation loss.
Available in YJP-700 and YJP-900 models, it supports sheet sizes from 126×100 mm (min) to 850×600 mm (max), adapting to 200-800g/m² paperboard, catering to diverse needs from small-size tags to large-size packaging boxes.
