Large‑Width Rubber Scraper Gun for Broad‑Area Hot‑Melt Application

Keqi large‑width rubber scraper gun features reverse‑suction structure for stable high‑speed wide‑format hot‑melt scraping, with maximum scraping width up to 700 mm. It solves broad‑area gluing pain‑points for corrugated cartons, large gift boxes and furniture panel bonding.The reverse‑suction design effectively reduces residual glue overflow and stringing when the gun stops dispensing. It supports adhesive viscosity up to 15 000 CPS and operates steadily above 3500 cycles per minute.

Temperature ranges 38‑230 °C, monitored by Ni120 / PT100 dual‑mode temperature sensors for reliable heat management.Working together with independent hot‑melt pump control systems, HEPA‑500 realizes uniform broad‑area hot‑melt layers. Universal mounting brackets enable installation on corrugated converting machines and automated assembly lines. Wear‑resistant scraper parts extend service life and cut spare‑part replacement frequency.

Main‑use scenarios cover large‑size corrugated shipping boxes, furniture board lamination and oversized gift‑box production. Manufacturers achieve even wide‑range hot‑melt coverage, improve bonding strength and reduce manual rework. It is an ideal upgrade for factories requiring high‑quality large‑format hot‑melt coating.
