Maintenance and management of general equipment production line for rubber product suppliers

1. Maintenance plan and cycle management
Before starting the machine every day, check the transmission belt tension, mold closing accuracy and temperature control stability of the heating system of the rubber product production line, and record the air pressure and hydraulic oil level. Focus on the rotor gap of the internal mixer and the wear of the extruder screw, and use an infrared thermometer to monitor the bearing temperature. Complete the flatness correction of the hot plate of the vulcanizer and clean the cooling water circuit. Regularly replace aging seals and perform oil spectrum analysis on the internal mixer reducer.

2. Core equipment maintenance technology
Check the wear of the rotor peak every 500 hours. When the wear exceeds the standard, it needs to be repaired by surfacing. Use double-lip skeleton oil seals and pneumatic sealing systems to prevent rubber leakage. The rotor bearing uses NLGI 2-grade high-temperature lithium-based grease, and the grease injection cycle is 72 hours/time. The amount of grease injection is based on the extruded sealing grease. Use hydrocarbon cleaning agent to remove residual release agent every month, and calibrate the parallelism of the hot plate by laser every quarter.

3. Temperature and humidity control
The workshop temperature is recommended to be controlled at 25±5℃ and humidity ≤60%RH to avoid abnormal fluctuations in the scorch time of rubber compound. The mixing area needs to be equipped with a local cooling system to prevent the Mooney viscosity of the rubber from rising by more than 5%.
The conveyor belt is equipped with an ionizing rod to eliminate static electricity, and the surface resistance must be ≤1×10^9Ω.
