I. Manual Adjustment Techniques
Adhesive Tape: Control tension by adjusting the nut; tighten clockwise and loosen counterclockwise.
Aluminum Foil: First set the initial tension, then adjust the attenuation value according to changes in roll diameter to avoid over-winding or over-winding.
II. Automatic Tension Control
Principle: The frequency converter adjusts the motor torque in real time according to changes in roll diameter to maintain constant tension.
Operation: Set the initial tension and attenuation value; the equipment runs automatically, suitable for high-speed production.
III. Parameter Setting Examples
BOPP/PE Material: Winding tension 3, taper 20%, contact pressure 0.2MPa.
Single-Layer PE Film: Winding tension 1.5, taper 30%, contact pressure 0.24MPa.
IV. Key Operating Points
Gradual Speed Increase: Start at a low speed to avoid sudden tension changes.
Regular Inspection: Ensure stable tension to prevent material wrinkling or breakage.
