CORRUGATOR BELT
also known as drying belt / conveyor belt for corrugated board) is a critical component in the corrugated board manufacturing process. It directly influences board quality, drying efficiency, and line stability.
Key positioning:
- Designed for paperboard conveying + optimized drying process
- Suitable for all major corrugator machine brands worldwide
- Especially effective in high-speed corrugated production lines
The belt ensures:
- Smooth and continuous paperboard conveying
- Straight-line running stability
- Even pressure transfer onto hot plates
- Supporting uniform drying of corrugated board
These functions ensure consistent board quality and reduced production defects.
Technical Performance and Advantages
Moving beyond standard specifications, our drying belt technology focuses on three critical operational pillars: moisture management, board surface integrity, and mechanical longevity.
- Extended Operational Life: Engineered for high-volume production, these belts consistently reach service lives of 750 working days or 45 million meters of corrugated board.
- Precision Drying Dynamics: The proprietary weave structure facilitates rapid moisture release, allowing the belt to quickly absorb and dissipate steam from the board during the drying phase.
- Surface Protection & Print Quality: Incorporates advanced flocked joint technology, preventing common issues like board indentation, crushing, or surface marking during heat-pressure application.
- Mechanical Stability: High-tensile strength construction (up to 70Mpa) ensures consistent geometric stability and straight-line running, even at high line speeds.
- Energy and Noise Efficiency: Optimized for low-noise operation at high speeds, improving the acoustic environment while maintaining high friction coefficients for stable transport.
Technical Specifications & Belt Selection
Our Corrugator drying belts are built with specific fiber compositions—blending cotton yarn, synthetic fibers, and IFDY—to balance heat resistance with durability.
| Specification | WSD-9G (High-Speed) | KWSD-95 (Armored) | QYD/MDD (Traction) |
|---|---|---|---|
| Primary Use | High-speed production | Variable width production | Bridge & palletizing |
| Heat Resistance | 200℃ | >350℃ (Edges) | 200℃ |
| Tensile Strength | 65 Mpa | 70 Mpa | 40 Mpa |
| Air Permeability | 300 m3/m2h | 400 m3/m2h | 2.5 m3/m2min |
Engineering Design & Integration
The design focuses on the belt's function as a heat and pressure transfer medium. The belt applies controlled pressure to bond the board to the heating plate, ensuring moisture is effectively pulled away from the fiber matrix through the belt's porous structure.
- Customized Engineering: KCB provides tailored belt dimensions (widths ranging from 600mm to 2800mm) and specifications to match the unique mechanical stress of your specific machine line.
- Maintenance & Repair: Our design features robust, repairable stainless steel fasteners and durable joint technology, simplifying maintenance without requiring the fabric to be thinned or re-cut.
