High‑Frequency Pneumatic Hot Melt Glue Gun for High‑Speed Folder‑Gluer Production

Keqi high‑frequency pneumatic hot melt glue gun delivers precise dot and bead‑line hot‑melt dispensing for printing‑packaging production lines. Supporting over 7000 cycles per minute, it keeps stable performance under ultra‑high‑speed continuous operation, matching modern high‑capacity folder gluers.With a compact installation footprint, this pneumatic glue gun can be retrofitted onto new or existing converting equipment without large‑scale mechanical reconstruction.

It handles mainstream hot‑melt adhesives including EVA, PSA and TPR, for adhesive viscosity ranging from 500‑5000 mPa.s. Max working temperature reaches 230 °C, controlled by reliable Ni120 temperature sensor to avoid glue carbonization and nozzle clogging.24 VDC high‑speed solenoid valve realizes instant on‑off control for clean glue cutoff without stringing or tailing. Operators adjust air pressure and adhesive pressure flexibly according to carton material and production requirements.

Its robust metal structure resists paper dust and ink contamination inside printing workshops and extends service life with low maintenance workload.It is widely deployed for cosmetic cartons, wine gift boxes, e‑commerce folding boxes and composite packaging. Factories adopting this gun achieve consistent hot‑melt bonding quality, reduce glue waste and lower reject rates caused by insufficient or uneven adhesive. As a modular component, it pairs perfectly with Keqi hot‑melt pump systems to build a complete inline hot‑melt gluing solution for post‑press converting.
