How long is the replacement cycle of wearing parts of the slitting machine

The replacement cycle of wearing parts of the slitter varies depending on various factors such as equipment model, frequency of use, working environment and maintenance. The following are approximate replacement cycles for some common wear parts, but please note that these cycles are for reference only and may need to be adjusted on a case-by-case basis:

1. Blades:

• Typically, the blade may need to be replaced after about 200 hours of use.

• If you notice a significant decrease in cutting effect or abnormal noise from the cutting machine during use, it may be a sign that the blade is severely worn, indicating that it needs to be replaced in time.

• For the round knife of the slitting machine, it is generally recommended to replace it after 200~300 hours of use.

2. Transmission Belt/Chain:

• Under normal conditions, it is recommended that the transmission belt or chain be fully inspected and maintained every 6 months to 1 year.

• If the drive train is used frequently or in a harsh working environment (e.g. moisture, corrosion, high temperature, high pressure, etc.), it may be necessary to shorten the maintenance interval, or even need to be inspected and maintained every 3 months or less.

3. Bearings:

• The life of industrial-grade rolling bearings varies from thousands to hundreds of thousands of hours, depending on a variety of factors such as load size, operating temperature, lubrication status, etc.

• For bearings for critical equipment or critical components, it is recommended to perform a maintenance check every 5,000 to 10,000 hours.

• If there are obvious problems such as wear, increased noise, abnormal temperature, poor rotation or reduced performance, the bearing should be inspected and replaced in time.

4. Guide rollers and pressure rollers:

• The replacement cycle of guide and pressure rollers is usually determined by their material, hardness, and the nature of the material they come into contact with.

• After long-term use, if its surface is severely worn or deformed, it should be replaced in time to ensure the cutting quality.

5. Other wearing parts (such as cork belts, belts, rewinding and unwinding clamps, etc.):

• The replacement cycle for these consumables also usually depends on the frequency of use and the working environment.

• It is advisable to regularly check the wear and tear of these parts and replace them according to the actual situation.

In addition, there are a few things to keep in mind:

• Manufacturers often provide recommendations on wear parts replacement cycles, which are based on equipment design and experience and are of important reference value.

• In actual operation, we should pay close attention to the operation status and cutting quality of the equipment, and stop the machine for inspection and consider replacing the relevant wearing parts once abnormalities are found.

• Regular maintenance of the equipment, such as cleaning, lubrication, etc., can extend the service life of wearing parts and reduce the failure rate.

To sum up, the replacement cycle of wearing parts of the slitting machine is a relatively complex issue, which needs to be judged and adjusted according to the specific situation. It is recommended that users refer to the manufacturer's recommendations and combine with actual usage to make a reasonable replacement plan.
