This HRP-01 pneumatic scraper hot melt gun is a dedicated slot scraping dispensing unit driven by a 24 VDC high-response solenoid valve, engineered for continuous uniform strip coating. It supports a maximum operating speed over 3500 cycles per minute to match medium and high-speed automatic folder gluers and composite laminating lines. Equipped with Ni120 precision temperature sensor, its maximum heating temperature reaches 200°C (392°F) to stabilize glue viscosity and avoid adhesive carbonization during long continuous shifts.

It adapts hot melt adhesives with viscosity up to 10,000 mPa.s, compatible with medium and high-viscosity EVA and PSA hot melts. The maximum effective scraping width is 35mm, delivering even flat glue layers without uneven thickness or missing coating areas. It runs stably under working air pressure of 3.1–5.5 bar (80–145 psi), with adjustable scraping thickness and width supportable in real time without complicated disassembly, drastically shortening mold change and production debugging time.

The integral metal modular body features compact installation dimensions, enabling flexible horizontal and vertical mounting on various automation equipment. It adopts universal 220VAC ±10%, 50/60Hz wide-frequency power supply suitable for global industrial power grids. Wear-resistant alloy internal valve cores guarantee stable mechanical performance, low clogging risk and extended service life under long-term high-frequency scraping operations.

The core advantage of this pneumatic scraper gun lies in its integrated slot scraping structure, which outputs continuous uniform flat glue strips, solving uneven coating defects caused by traditional dot or narrow line dispensing guns and cutting defective product rates significantly. Real-time parameter adjustment on the gun body eliminates tedious disassembly and calibration work, accelerating product switching efficiency for multi-variety production workshops.

With cycle speed exceeding 3500 times per minute, it fully keeps pace with medium-high speed packaging and composite assembly lines to lift overall factory throughput. It has broad adhesive compatibility, handling high-viscosity hot melt glue up to 10,000 mPa.s to cover multiple lamination and edge-sealing processes. Its compact modular design can be flexibly installed on folder gluers, roll laminators and automated jigs without occupying extra production space.

Hardened internal wear parts reduce long-term maintenance frequency and spare part costs. Precise constant temperature control stabilizes glue fluidity to prevent aging and nozzle blockage. Compared with deploying multiple single-line narrow nozzles, one HRP-01 scraper gun realizes complete 35mm full-width coating, simplifying pipeline layout and lowering customers’ overall equipment investment for surface lamination and edge bonding processes.

The HRP-01 pneumatic scraper gun is a professional dispensing accessory designed for continuous flat strip hot melt scraping coating, widely deployed across packaging printing, textile composite, furniture and light manufacturing industries. In the packaging sector, it performs full-edge uniform scraping bonding for wine boxes, cosmetic gift boxes and food cartons, forming neat consistent glue layers on coated paper and UV-laminated substrates without scratching printed patterns, perfectly matching medium-speed automatic folder gluer production lines.

It dominates fabric and non-woven composite processes including mattress edge lamination, shoe surface material fitting and filter element compounding, providing full-width even adhesive layers to strengthen composite firmness and surface flatness. It also fits thin wood veneer lamination, small electronic component surface bonding and disposable hygiene material edge sealing.

It can perfectly match Keqi gear-type heating pumps and pneumatic heating pump main machines to build multi-station synchronous coating systems. Its flexible mounting structure adapts to roll-to-roll laminating machines and automatic jigs, ideal for mass continuous lamination manufacturers.
