1. Slitting system faults: Burrs on the cut edge and uneven cuts (associated with error code 7011), caused by blade wear or malfunctions in the cutter positioning sensor.
2. Conveying drive faults: Conveyor belt misalignment and abnormal speeds (associated with error code 32), leading to loss of tension control and uneven winding tightness.
3. Electrical control faults: Photoelectric tracking deviations and false sensor readings, resulting in slitting position errors and compromised dimensional accuracy.
4. Surface quality faults: Scratches on the aluminum foil surface and indentations caused by aluminum dust, typically resulting from jammed guide rollers or aluminum debris adhering to the blade surface.
