HRP‑01 Pneumatic Scraper Gun – Reliable Medium‑Width Strip Hot‑Melt Application

Keqi HRP‑01 pneumatic scraper gun provides high‑speed, precise medium‑width hot‑melt scraping for general‑purpose packaging production lines, with max scraping width 35 mm.It runs above 3500 cycles per minute and handles adhesive viscosity up to 10 000 CPS.

Working temperature max 200 °C, monitored by Ni120 temperature sensor. The 24 VDC solenoid valve ensures fast response for stable strip‑glue formation.Thanks to universal mounting structure, HRP‑01 can be added to almost all existing converting machines.

Operators perform real‑time adjustments for glue thickness and position during production without complex shutdown debugging. Reinforced alloy scraper components offer long service life under continuous workshop operation.Main applications include gift‑box flap sealing, e‑commerce carton edge bonding and craft‑packaging processing. Printing workshops replace unstable manual strip‑gluing workstations. By pairing HRP‑01 with Keqi hot‑melt pump units, factories obtain consistent hot‑melt strip quality, reduce reject rates and improve overall post‑press automation level with moderate investment.
