Product Details
Feeding Control Buttons
- Real-time detects the edge position of kraft paper rolls during running.
- Transmits deviation signals to the servo edge correction system to automatically adjust paper horizontal position.
- Keeps paper running straight without left-right offset, guarantees uniform window die-cutting and bag size precision.
- Adjustable mounting bracket, fits all paper widths within the machine’s processing range.
Window Die-Cutting Roller
- Equipped with customized square die-cut mold, punches precise window outline on kraft paper continuously at high speed.
- Synchronized with main servo motor, matches paper feeding speed to ensure window position consistency.
- Hardened alloy roller surface, wear-resistant for long-term mass production. Different mold sizes are replaceable for various window dimensions.
- Pre-cuts window holes before film lamination, preparing blank positions for transparent window film pasting.
Press Roller Unit
- Elastic orange silicone roller firmly presses transparent PP/PET window film onto pre-cut window holes of paper.
- Even pressure eliminates bubbles and warping between paper and film, realizing tight, leak-free window adhesion.
- Adjustable up-down pressure to adapt to different paper thickness (45–150g/m²) and film thickness.
- Stabilizes paper transportation after window patching, avoids paper jumping before bottom forming station.
Color Mark Tracking Positioning System
- High-precision color mark sensor scans printed register marks on pre-printed kraft paper.
- Feeds position signals to Mitsubishi servo controller to synchronize feeding, die-cutting and window patching speed.
