Cooked Food Vacuum Packing Machine is a packaging equipment used for food preservation. It extends the shelf life of food by extracting the air from the packaging bag and sealing it. To ensure the normal operation of the equipment and extend its service life, regular maintenance is required, and common faults need to be troubleshooted in a timely manner.

1. Maintenance Guide for Cooked Food Vacuum Packing Machine:
   • Cleaning: After each use, clean the workbench and seal strips to prevent food residue adhesion. Regularly clean the oil window of the vacuum pump to ensure that the oil level is within the normal range. Check and clean the filter to prevent dust and impurities from affecting the air extraction effect.
   • Lubrication and Maintenance: Timely add lubricating oil to the transmission components to ensure the smooth operation of the machinery. For machines with heating devices, ensure the cleanliness of the heating elements to ensure good heat conduction effect.
   • Electrical Inspection: Regularly check the electrical circuits and switches to ensure there is no wear or loosening. Check if the grounding is good to prevent the occurrence of leakage accidents.
   • Seal Inspection: Check the wear of the seal strip. If damaged, replace it in time to maintain a good sealing effect.
   • Vacuum Degree Inspection: Regularly test the vacuum degree. If it does not meet the standard, it may be necessary to check the vacuum pump or other related components.
2. Troubleshooting of Common Faults of Cooked Food Vacuum Packing Machine:
   • Insufficient vacuum degree: Check if the vacuum pump is working properly and whether the pump oil needs to be replaced. Check for leaks in the vacuum pipeline. Check if the packaging bag is damaged, causing air leakage.
   • Unsecured sealing: Adjust the sealing time or temperature to ensure that the sealing material can be fully melted and bonded. Check if there is any dirt on the sealing area, which affects the sealing quality.
   • Machine fails to start: Check the power socket and cable for any issues. Check if the settings on the control panel are correct. Check if the emergency stop switch and other safety devices have been triggered.
   • Excessive noise: Check for loose parts or foreign objects interfering with the operation. Check if the vacuum pump is normal and whether it needs maintenance or replacement.
   • Abnormal temperature: If the heating is not normal, check the heating element and thermostat for proper functioning. If the temperature is too high, it may be a problem with the cooling system, and the fan or radiator needs to be cleaned.
