In the process of PET bottle recycling and reuse, PET bottle label remover machine is a key piece of equipment for removing labels from the surface of PET bottles to ensure the quality of the material. However, plastic label removing machine may have various faults in the process of use, which affects their normal operation.
Worn or damaged PET bottle label remover machine blades
Prolonged use or cutting intense labels may cause the plastic label removing machine blade to wear out. Improper maintenance, cleaning or operation can also damage the blades. When the de-labeling machine blade is worn or damaged, labels may not be completely removed, not cut cleanly, or not cut accurately.
Solutions
- Regularly check blade wear: Check the condition of the PET bottle label remover machine blade regularly according to the frequency of use and replace worn blades promptly.
- Proper operation and maintenance: Avoid applying excessive pressure to the blade during use, clean the blade regularly and use the proper lubricant.
- Choose high-quality blades: Use high-quality, wear-resistant blades to prolong service life.
De-labeling machine drive system failure
Extended use of belts, chains or gears in the driveline can cause wear and tear, leading to transmission failure. Additionally, improper lubrication and maintenance can also cause driveline failure. Transmission system failure may cause the PET bottle label remover machine to operate abnormally, with problems such as jamming, stopping, or slow speed.
Solutions
- Regular inspection of transmission parts: Check the wear level of transmission parts regularly and replace worn parts in time.
- Proper lubrication and maintenance: Lubricate with the proper lubricant and perform regular maintenance according to the manufacturer’s recommended maintenance schedule.
Label was not completely removed
Labels are not completely removed from PET bottles after processing in the PET bottle label remover machine due to worn blades, outdated remover, or incorrect operating parameters, leaving a residue.
Solutions
- Check the drive system of PET bottle label remover machine, replace worn belts or adjust belt tension.
- Ensure stable power supply and troubleshoot power supply problems.
- Set a suitable production cycle to avoid long periods of high-load operation, and attach a heat sink to the de-labeling machine if necessary.
Abnormal noise of the plastic label removing machine
When the PET bottle label remover machine is running, there is an abnormal noise, beyond the normal working sound level. The abnormal noise may be caused by worn or loose machine parts or improper lubrication. After prolonged use, PET label remover machine parts may be worn, and bearings or gears may be loose, or lack the necessary lubrication.
Solutions
- Check PET label remover machine parts for looseness or wear, and replace parts that need to be replaced.
- Perform regular lubrication maintenance to ensure normal friction between parts when the plastic label removing machine is running.
