KQ-PJ23 Cold Glue Dispenser for Corrugated Flexo Printing Lines

KQ-PJ23 is a dedicated cold glue dispensing machine customized for corrugated flexo printer slotter machines, replacing traditional tank roller gluing with efficient non-contact spray gluing to solve core corrugated packaging production pain points. Conventional roller gluing limits machine speed below 150 sheets per minute and generates massive glue waste from overflow; PJ23 boosts line speed while cutting glue consumption by 30%–50%.Equipped with exclusive flexo machine fixed mounting jig, the unit installs directly on flexo printer conveying frames without extra auxiliary brackets. Air pressure controlled spray technology delivers precise glue placement only on required bonding areas, avoiding glue smudge on printed patterns of color corrugated boxes.

The closed spray structure requires minimal daily maintenance; operators only cap nozzles after shutdown without full tank cleaning.Adjustable spray width and glue flow adapt single-wall, double-wall and triple-wall corrugated boards of different thicknesses. Synchronous signal linkage with flexo printer conveying speed ensures glue tracks align perfectly with carton flap positions, eliminating offset gluing during high-speed sheet feeding.Main applications cover express logistics corrugated boxes, fruit transport cartons, home appliance outer packaging and agricultural product shipping boxes. Corrugated manufacturers installing KQ-PJ23 raise overall line throughput, reduce glue raw material expenditure and eliminate finished box degumming caused by uneven roller gluing.
