How to adjust the gap and angle of the blade or disc knife of the Paper Roll Slitting Rewinding Machine?

Adjusting the gap and angle of the blade or disc knife of the Paper Roll Slitting Rewinding Machine is a key step to ensure the quality of slitting and rewinding. Here are some detailed adjustment methods and precautions:

Ⅰ. Adjust the gap of the blade or disc knife

1. Shutdown and power off: First, make sure that the rewinder has completely stopped running and cut off the power supply to prevent accidents during the adjustment process.

2. Clean the work area: Clean up the debris and dust around the rewinder and near the blade or disc knife, and keep the work area clean for precise adjustment.

3. Loosen the fixing device: Use appropriate tools to loosen the fixing screws or devices of the blade or disc knife so that it can move freely.

4. Adjust the gap:

  Horizontal gap: Adjust the horizontal gap between the blade or disc knife and adjacent components (such as knife holder, track, etc.) to ensure that the gap is uniform and consistent, and avoid uneven slitting or damage to the material due to excessive or too small gap.

  Vertical gap: For situations where the vertical gap needs to be adjusted (such as the gap between the blade and the pressure roller), it can be achieved by adjusting the height of the relevant components. Use measuring tools (such as vernier calipers, micrometers, etc.) to make precise measurements to ensure that the gap reaches the preset value.

5. Tighten the fixing device: After adjusting in place, tighten the fixing screws or devices immediately to prevent the blade or disc knife from shifting during use.

6. Test the effect: Perform a trial cut to verify the adjustment effect. If there is still uneven slitting or poor cutting effect, continue to fine-tune until you are satisfied.

Ⅱ. Adjust the angle of the blade or disc knife

1. Find the angle adjustment device: First, find the angle adjustment device of the blade or disc knife (such as adjustment screws, adjustment handles, etc.). These devices are usually located on the fixed seat of the blade or disc knife.

2. Loosen the fixing device: Use appropriate tools to loosen the fixing screws or devices of the angle adjustment device so that it can rotate freely.

3. Fine-tune the angle: According to production requirements or cutting effects, gradually adjust the angle of the blade or disc knife. The adjustment amplitude should not be too large each time to avoid excessive deviation. Use measuring tools for precise measurement to ensure that the angle reaches the preset value.

4. Fix the angle adjustment device: After adjusting in place, tighten the fixing screws or devices of the angle adjustment device immediately to ensure that the blade or disc knife maintains a stable angle during the production process.

5. Test the cutting effect: Perform a trial cut to check the cutting effect. If there are still burrs, tears or uneven cutting, continue to fine-tune the angle until you are satisfied.

Precautions

1. Safety first: During the entire adjustment process, be sure to follow the safety operating procedures to ensure personal and equipment safety. Wear personal protective equipment (such as safety helmets, protective glasses, protective gloves, etc.).

2. Accurate measurement: Use accurate measuring tools to adjust the gap and angle to improve the adjustment accuracy.

3. Gradual adjustment: Avoid making large adjustments at one time to avoid irreversible damage to equipment and products.

4. Regular inspection: Establish a regular inspection system to regularly check and adjust the gap and angle of the blade or disc knife to ensure the continuous stability of the slitting and rewinding quality.

5. Professional operation: For complex adjustment work, it is recommended that professional technicians perform the operation to ensure the adjustment effect and the normal operation of the equipment.
