1. Check that the automatic temperature control and heating elements are functioning properly. Adjust the heating temperature at each point to ensure it is within the specified range.
2. Check the traction speed and control the film thickness.
3. Observe and adjust the film thickness uniformity, ensuring the folded diameter meets standards.
4. Check the air reservoir pressure; it should not be too high, but there should be backup pressure.
5. Check and control the raw material ratio and ensure it is mixed evenly.
6. Check the raw materials for impurities, especially using a magnet to check for any iron particles mixed in.
7. Check the lubrication of the gearbox and air compressor cylinders.
8. Regularly check the temperature rise of each operating motor and the mechanical transmission.
