I. Incorrect Tension Parameter Settings
Excessive unwinding tension: Causes material stretching and deformation, affecting slitting accuracy.
Insufficient winding tension: Leads to uneven winding 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 malfunction: Failure to calibrate or replace regularly leads to inaccurate tension detection.
Wear of transmission system components: Wear of belts, gears, etc., affects the stability of tension transmission.
IV. Common Problems and Solutions
Uneven winding: Replace the paper core and use a winding pressure roller.
Material wrinkling: Adjust the winding tension and use a pressure roller. Inaccurate meter reading: Adjust the meter wheel contact or replace the meter wheel.
Operating points:
Gradually increase speed: Start at a low speed to avoid sudden tension changes.
Regular inspection: Ensure stable tension to prevent material wrinkling or breakage.
