Retrofit‑Friendly Design of KQ‑PJ23 for Existing Corrugated Flexo Production Lines

Many corrugated packaging factories want to improve gluing quality but refuse to replace complete flexo printing machines due to high procurement cost and long production‑stop losses. KQ‑PJ23 cold glue dispensing machine is engineered for convenient inline retrofitting rather than full‑machine replacement of existing equipment.

The complete set includes supporting roller frame, HB6 glue feeding pump, LD6 array nozzle group and LD3 touch‑screen controller. Universal dedicated mounting bracket fits most flexo printer models on market without destructive mechanical reconstruction. After simple positioning fixing, hose connection and signal synchronization debugging, the unit can go online quickly with short downtime.All key parameters such as glue volume, spray timing and trigger logic can be adjusted on the intuitive touch panel.

Operators store parameter presets for repeated box styles, shortening product change‑over time for mixed‑spec corrugated orders. The durable industrial‑grade structure adapts dusty, high‑vibration corrugated‑workshop environment for long‑shift continuous running.It is widely retrofitted on flexo folder‑gluer lines for e‑commerce shipping cartons and agricultural‑product packaging. Small‑to‑mid‑size corrugated plants gain precise non‑contact spray‑gluing capacity with moderate investment, solving old‑equipment gluing defects without discarding current production hardware.
