Working Principle of Spiral Paper Tube Machine – Training Operation Points
1. Core Working Principle (Key for Operation)
Automatically form paper tubes by spirally winding glued paper strips around a rotating mandrel, then drying and cutting to preset length.

2. Key Operation Steps (Sequence & Focus)
- Paper Unwinding & Slitting: Mount parent paper rolls on unwinding unit (keep stable tension); slit paper web into required-width strips with one set of paper slitting rewinding machine.
- Gluing: Apply uniform glue to one/both edges of strips (ensure strong layer bonding).
- Spiral Winding (Core Step): Feed glued strips at precise spiral angle to rotating mandrel; control tension/angle via CNC to ensure even overlap and consistent diameter (multiple strips for thicker walls).
- Precision Cutting: Cut long tube into preset length with rotary cutter.
3. Key Components & Their Functions
- Unwinding Unit: Stable tension feeding of paper strips.
- Gluing System: Even adhesive application.
- Winding Mandrel: Determines tube inner diameter and shape.
- CNC Control Panel: Adjust winding angle, tension, speed, cutting length (real-time).
- Drying/Cutting Units: Harden tube and trim to size.
4. Critical Notes (Avoid Faults)
- Keep tension stable during unwinding to prevent paper jams.
- Ensure uniform gluing to avoid layer separation.
- Monitor CNC parameters (spiral angle, speed) for consistent tube quality.
