1. Wrinkled Coil
Possible Causes:
Improper Tension Control.
The surface of the guide roller is not flat or has foreign matter.
The quality of the coil itself is poor.
Solution:
Adjust the tension control system to ensure that the tension of the coil is uniform during the rewinding process.
Clean the surface of the guide roller to ensure that it is flat and free of foreign matter.
Check the quality of the coil and replace the coil of poor quality.
2. Coil Breakage
Possible Causes:
Excessive Tension.
Uneven Coil Thickness.
The tool is worn or improperly set.
Solution:
Reduce the tension to ensure that the coil is not overstretched during the rewinding process.
Check the thickness of the coil to ensure that it is uniform.
Check the tool, replace the worn tool or adjust the tool setting.
3. Uneven Rewinding
Possible Causes:
The rewinding shaft is not parallel.
Unstable Tension Control.
The edge of the coil is not neat.
Solution:
Check the rewinding shaft to ensure that it is parallel and installed correctly.
Adjust the tension control system to ensure stability.
Check the edge of the coil to ensure it is neat.
4. The equipment is running too noisy
Possible reasons:
Bearings are worn or lubricated insufficiently.
Drive belts are loose or worn.
Gearbox failure.
Solution:
Check bearings, lubricate or replace.
Check drive belts, tighten or replace.
Check gearboxes, repair or replace.
5. The equipment cannot start or stops suddenly
Possible reasons:
Power failure or unstable voltage.
Control system failure (such as PLC or inverter failure).
Safety protection device is triggered (such as emergency stop button, overload protection).
Solution:
Check the power supply line to ensure stable voltage.
Check the control system, repair or replace faulty parts.
Check safety protection devices, reset or repair.
