Under normal circumstances, the regular maintenance of the blow molding machine equipment is once a year, and the time is often arranged during the first few days of the holiday break or during the holidays. The equipment management personnel participate in the guidance work, and the equipment maintenance workers and operators cooperate. jobs. The main contents of the regular maintenance work on the equipment are as follows:

1. Clean and scrub the oil on all parts of the blow molding machine and the dust inside the electric control box;
2. Disassemble the reduction gear box and bearing gland, check the quality of the lubricating oil and the amount of metal powder in the oil, and clean and change the oil if necessary;
3. Check the wear of various transmission parts. The gears with more serious wear should be surveyed and prepared, and be replaced when preparing for next maintenance;
4. Check the wear of the belt in the V-belt drive, and adjust the tightness of the V-belt installation. The V-belt with serious wear should be replaced;
5. Check the wear of the barrel and the screw. For mild scratches and worn rough surfaces, use oil stone or fine sand cloth to smooth and smooth, and record the measured dimensions of the barrel and screw working surface;
6. Record the V-belt model specifications and bearing model specifications with more serious wear. After the maintenance work, propose the damaged parts ordering plan and prepare for the next maintenance;
7. Check and correct the heating temperature of the barrel of the blow molding machine (measured by the mercury thermometer) and the temperature difference between the meter display to ensure the correct operation of the extrusion process temperature;
8. Adjust and test each safety reporting device to verify its reliability and accuracy;
9. Test and inspect whether the various pipelines (water, gas and lubricating oil) are unobstructed, and repair the leaks and blocked parts.
10. Check and adjust the position of the electric heating device, cooling fan and safety cover; ensure that they can work normally and effectively.
