I. Incorrect Tension Parameter Settings
Excessive Unwind Tension: Causes material stretching and deformation, affecting slitting accuracy.
Insufficient Rewind Tension: Leads to uneven rewinding and even material wrinkling.
Improper Tension Attenuation Setting: Causes large tension fluctuations during high-speed operation, affecting product quality.
II. Improper Operation
Failure to Adjust Tension According to Material: Different materials (e.g., BOPP, PE, aluminum foil) require different tension parameters; blindly setting them can easily lead to poor slitting.
Untimely Tension Adjustment: Failure to adjust tension in real time according to changes in roll diameter during operation leads to unstable tension.
III. Insufficient Equipment Maintenance
Tension Sensor Failure: Failure to calibrate or replace the sensor regularly leads to inaccurate tension detection.
Wear and Tear in the Transmission System: Wear and tear on belts, gears, and other components affects the stability of tension transmission.
IV. Common Problems and Solutions
Uneven Rewinding: Replace the paper core and use a rewinding pressure roller.
Material Wrinkling: Adjust the rewinding tension and use a pressure roller. Inaccurate meter reading: Adjust the meter wheel contact or replace the meter wheel.
