Daily startup cleaning for the 90 butyl sealant production line: pre-startup inspection, mid‑production patrol checks, and shutdown cleaning and maintenance.

Daily Startup/Shutdown Maintenance

Pre-Startup Inspection

  1. Check the water level and quality of the circulating cooling water tank, ensure that the cooling water lines are free of blockages and leaks, and verify that the barrel and die head are adequately cooled to prevent high‑temperature carbonization of the butyl rubber.
  2. Check the vacuum pump oil level and oil condition; ensure there is no oil shortage or emulsification/cloudiness, and that the vacuum piping is airtight to prevent bubbles and pinholes in the finished product.
  3. Inspect the reducer and the servo winding motor for unusual noises and oil leaks, and verify that the emergency stop button, temperature control instrument, and touch screen are functioning properly.
  4. Clean debris and any residual hardened butyl rubber from the feed inlet to prevent material blockage and slippage; verify that the safety guard is in good condition.
  5. Inspect the winding ribbon guide rails and tension roller surfaces for residual adhesive, and wipe them clean to prevent adhesive‑induced scratches on the roll material.

In-process inspection

  1. Check the temperature of each zone every 30 minutes to prevent localized overheating, which can cause the rubber compound to yellow and age.
  2. Inspect the discharge condition for broken strands,胶溢出, and impurities, and replace the filter screen promptly.
  3. Servo-driven winding tension and cable‑laying operation are stable, with no edge collapse or stretching of the wound material.
  4. Check for any abnormal noises or vibrations during equipment operation, and ensure that the motor and gearbox do not exhibit excessive temperature rise.

Shutdown for Cleaning and Maintenance

  1. Short-term shutdown: Run the machine at low speed with no load for 3–5 minutes to completely purge any residual butyl rubber from the barrel, thereby preventing mold blockage and vulcanization.
  2. Long-term shutdown for the day: Cool down to below 60°C, disassemble the feed hopper and clean residual adhesive from the inner walls; thoroughly wipe the die head and mold head, then apply a release coating for protection.
  3. Wipe away any excess adhesive and oil stains from the entire machine surface to keep the equipment clean; clear away any waste adhesive that has fallen on the floor.
  4. Shut down the water pump, vacuum pump, and heating power supply, and maintain accurate equipment operation records (including temperature, production output, and any malfunctions).
