KQ‑PJ23 Cold Glue Dispensing Machine — Upgrade Gluing Performance for Corrugated Flexo Folder Gluer

Traditional disc‑type tank gluing widely used on corrugated flexo printers faces obvious bottlenecks. It is usually limited to production speed below 150 sheets per minute. Glue output fluctuates with adhesive viscosity, frequently triggering overflow glue or insufficient coating, bringing high reject risk for finished shipping cartons.KQ‑PJ23 is purpose‑built spray‑type cold glue dispensing solution for corrugated flexo production lines.

Equipped with LD3 three‑channel controller, HB6 glue pump and LD6 array nozzle assembly, it adopts air‑pressure‑controlled non‑contact spraying to deliver precise, adjustable glue volume without overflow. Compared with roller‑disc gluing, customers achieve 30‑50 % cold‑glue material savings directly, cutting long‑term raw‑material expenditure for corrugated plants.Its dedicated flexo‑machine mounting jig supports retrofitting onto most mainstream flexo printer brands, requiring minimal frame modification.

Operators adjust glue flow and spray parameters via touch‑screen HMI for different corrugated thickness and order specifications. Daily maintenance workload is greatly reduced; users only need to cap nozzles after shutdown instead of full‑tank daily cleaning work.This system serves express‑delivery corrugated boxes, fruit transport cartons and commodity outer packaging. It helps corrugated converters break old‑process speed limits, stabilize bonding quality and lower carton‑opening complaints from end‑customers, becoming a practical process‑upgrade choice for flexo printing facilities.
