Slitter troubleshooting and solutions

Slitter troubleshooting and solutions are the key to ensuring the normal operation and productivity of the equipment. The following are some common faults and how to troubleshoot and resolve them:

1. The slitting size is not accurate

• Possible causes:

。 Worn or loose knives.

。 The material tension is uneven.

。 The correction device is out of order.

。 Encoder or sensor failure.

•Solution:

。 Inspect and replace worn tools and tighten loose parts.

。 Adjust the tension control system to ensure uniform material tension.

。 Calibrate the guiding device to ensure that the material is in the correct position.

。 Check the encoder and sensor and replace it if necessary.

2. The edge of the material is burred or the cut edge is not neat

• Possible causes:

。 The cutter is blunted or damaged.

。 Improper adjustment of the tool clearance.

。 The thickness of the material is uneven.

。 The slitting speed is too fast.

•Solution:

。 Changing or grinding tools.

。 Readjust the tool clearance to match the thickness of the material.

。 Inspect the upstream equipment to ensure that the material thickness is uniform.

。 Reduce the slitting speed to ensure the cutting quality.

3. Broken or wrinkled material

• Possible causes:

。 The tension is too high or too small.

。 The guide rollers are not parallel or the surface is damaged.

。 The material itself is defective.

。 The slitting speed does not match the upstream and downstream equipment.

•Solution:

。 Adjust the tension control system to ensure that the tension is appropriate.

。 Inspect the guide rollers to make sure they are parallel and have a smooth surface.

。 Check the quality of the material and replace the defective material.

。 Adjust the slitting speed to ensure synchronization with upstream and downstream equipment.

4. Untidy or uneven winding

• Possible causes:

。 Improper control of winding tension.

。 The winding shaft is deformed or eccentric.

。 Material slitting widths are inconsistent.

。 The winding speed does not match the slitting speed.

•Solution:

。 Adjust the winding tension to ensure uniformity.

。 Check the reels and replace them if necessary.

。 Check the slitting width to make sure it's consistent.

。 Adjust the winding speed to ensure synchronization with the slitting speed.

5. The equipment is running too noisy

• Possible causes:

。 Bearings are worn or inadequately lubricated.

。 The transmission belt is loose or worn.

。 Gearbox failure.

。 The base of the device is unstable.

•Solution:

。 Check the bearings, lubricate or replace.

。 Check the transmission belt, tighten or replace.

。 Inspect the gearbox, repair or replace.

。 Reinforced base of the device to ensure stability.

6. The slitter machine cannot be started or stops suddenly

• Possible causes:

。 Power failure or voltage instability.

。 Control system failures (e.g. PLC or drive failures).

。 Triggered by safety protection devices (e.g. emergency stop button, overload protection).

。 Sensor or encoder failure.

•Solution:

。 Check the power supply line to make sure the voltage is stable.

。 Inspect the control system and repair or replace faulty parts.

。 Check the safety guard, reset or repair.

。 Inspect sensors and encoders and replace them if necessary.

7. The accuracy of the slitting machine decreases

• Possible causes:

。 Wear and tear of mechanical parts (e.g. rails, lead screws).

。 The control system parameter settings are incorrect.

。 Material tension fluctuations.

。 Changes in ambient temperature or humidity.

•Solution:

。 Inspect mechanical parts and replace worn parts.

。 Recalibrate control system parameters.

。 Adjust the tension control system to ensure stability.

。 Control the temperature and humidity of the environment to reduce the impact on the equipment.

8. Oil leakage or abnormal oil pressure of the slitting machine

• Possible causes:

。 Hydraulic system seals are damaged.

。 The oil circuit is blocked or the oil pump is faulty.

。 Insufficient or contaminated oil.

•Solution:

。 Inspect seals and replace damaged parts.

。 Clean the oil circuit or replace the oil pump.

。 Replenish or replace fluids.

summary

The troubleshooting of the slitting machine needs to start from mechanical, electrical, control system and other aspects. Regular maintenance, timely replacement of wearing parts, and keeping equipment clean are the keys to reducing breakdowns. For complex faults, it is recommended to contact the equipment manufacturer or professional maintenance personnel to deal with it.
