The Fully Automatic Non-Partitioned Folding and Gluing Production Line is a high-precision, fully automated system designed for continuous folding and gluing of filter materials without partition dividers.
It integrates pre-slitting, folding, hot-melt gluing, cooling, and synchronized conveying into one efficient workflow, ensuring consistent product quality and high production efficiency.
Developed for industrial air filters, automotive filters, and other pleated filtration products, this production line features intelligent control systems, servo-driven mechanisms, and adjustable folding parameters, making it suitable for diverse filter specifications.

1. High-Speed Production – Production speed adjustable between 2–15 m/min for optimized output.
2. Adjustable Folding Height – Folding height from 12 to 100 mm, controlled via touch screen.
3. Precision Corrugation – Uniform corrugation spacing ensures high flatness and consistent product quality.
4. Advanced Gluing System – 50L hot-melt glue machine with dual 26-point independent glue guns, each nozzle individually controlled.
5. Flexible Glue Application – Supports continuous, single-sided, double-sided, surface-cutting, offset, and fold-count-controlled glue injection.
6. Synchronized Conveying – Servo-controlled conveyor belt ensures consistent spacing between filter materials.
7. Durable Mechanical Structure – Thickened aluminum profiles, chromium-plated shafts, and robust aluminum alloy frame provide long-term stability.
8. Intelligent Touchscreen Control – 10-inch touch screen for adjusting folding speed, glue volume, and process parameters.

The production line begins by feeding filter material and performing pre-slitting using the dual knives. The material then enters the folding mechanism, where the folding height and corrugation spacing are precisely controlled by servo motors and high-precision reducers.
The hot-melt glue system applies adhesive to the pleated materials through dual 26-point glue guns, with each nozzle individually controlled via a touchscreen interface. The glue is then cooled naturally and by fans to stabilize the material.
The conveyor belt system is servo-controlled, ensuring synchronized movement of folded and glued materials while allowing precise control of spacing between each filter. All parameters, including folding speed, glue application, and conveyor synchronization, are programmable through the PLC controller, ensuring high consistency and minimal manual intervention.
