Case Study: Full-Automatic PP Intermittent Gluing Production Line (2nd Generation)

1. Precision Gluing Technology
   • Dual 36-point spray glue assemblies with 52 solenoid valves, enabling independent control of each glue nozzle for intermittent gluing, single/double-sided application, and break-point gluing.
   • 50kg hot-melt glue machine ensures consistent adhesive flow, compatible with EU REACH-compliant materials.
2. Intelligent Synchronization
   • INOVANCE servo motors and reducers (New Standard) control folding and conveyor speeds, achieving ±0.5mm glue spacing accuracy and zero material waste from misalignment.
   • Touchscreen interface allows real-time adjustment of gluing patterns, folding heights, and line speed, with recipe storage for 20+ filter models.
3. Industrial-Grade Durability
   • Thickened aluminum profile frame and electroplated hard chrome shafts resist corrosion from glue residues, ensuring 80,000+ hours of service life.
   • Modular design with quick-release 胶枪 (glue guns) reduces maintenance time by 40%, supporting 24/7 production.
4. Environmental Compliance
   • Low-VOC adhesive application and energy-efficient 15kW power consumption meet EU Eco-Design Directive (ErP) standards.
   • Closed-loop glue circulation system minimizes waste, aligning with the client’s zero-landfill initiative.

Project Outcome

• Efficiency: Increased daily production from 8,000 to 15,000 filter elements, with glue consumption reduced by 20% through precise nozzle control.
• Quality: Achieved 99.7% gluing accuracy, eliminating manual rework and ensuring compliance with EN 779 air filter standards.
• Flexibility: Successfully adapted to produce HEPA filters, automotive cabin filters, and industrial dust collectors, supporting the client’s market diversification.
