Four Independent Air Knives for Effective Water Removal Before Winding PP Strap Production Line
Thorough removal of residual moisture from PP strap surfaces after secondary cooling/setting and before winding is critical. This production line features four independent high-pressure air knife units positioned at the secondary setting water tank outlet. Each unit corresponds to one product strand, delivering uniform, powerful airflow that acts as a precision "knife" to efficiently scrape water film from both top and bottom strap surfaces. This ensures completely dry product entry into the winding process, preventing issues such as unclear embossing, winding adhesion, roll mildew, or product corrosion caused by trapped moisture, thereby guaranteeing final product quality and storage stability.
- Configuration: 4 independent air knife sets, one-to-one对应 with the 4 product strands
- Working Principle: Utilizes compressed air to generate high-speed laminar airflow for surface blow-off
- Core Function: Thoroughly dries residual surface moisture on the product before winding
- Direct Benefit: Improves embossing and winding quality, prevents moisture-related defects
