Modular & Retrofit‑Friendly Design of Cold Glue System

Many packaging converters want to upgrade gluing performance without purchasing brand‑new folder gluers. KQ KPM‑PJ‑V24 cold glue dispensing system adopts fully‑modular hardware layout, designed for inline retrofitting on most new and legacy folding‑carton production equipment.Users can select 4‑channel or 8‑channel HZ4 controller according to gun quantity requirements, and match HB6 glue pump plus PJ‑4000 dispensing valves for 1‑4 spraying heads.

The standard supporting roller frame enables simple mechanical mounting. No destructive frame cutting is required; installation mainly includes bracket fixing, hose routing and signal synchronization debugging. Production downtime for commissioning can be finished within one shift.All core gluing parameters are centrally managed on the HZ4 touchscreen.

Each dispensing valve can be independently configured for glue output and trigger timing, which brings great flexibility for mixed‑spec carton production. The system can also work cooperatively with Keqi glue‑detection sensors and automatic ejectors to build closed‑loop QC workflows.It serves small‑medium printing workshops and large packaging groups. Factories gain high‑precision non‑contact cold‑glue capability with moderate investment, solving common pain‑points such as uneven glue and overflow defects from old roller‑gluing stations.
