Daily maintenance and care procedures for rubber hose extruders: cleaning and debris removal are essential; maintain the lubrication system; inspect critical components; adjust process parameters; and document maintenance activities.
I. Cleaning and Accumulation Management
Clean up promptly after production.
- After each production run, promptly clean residual rubber from the screw, barrel, molds, and other components to prevent it from hardening upon cooling and becoming difficult to remove.
- Use specialized tools, such as scrapers and soft-bristle brushes, in conjunction with solvents like rubber‑specific cleaners to assist with cleaning, thereby preventing damage to the equipment’s surface.
Regular deep cleaning
- Conduct a thorough disassembly and inspection of molds, filter screens, and other components prone to material buildup at least once a week to ensure no residues remain that could affect subsequent production.
II. Lubrication System Maintenance
Lubrication of transmission components
- Daily check the lubricant level in transmission components such as gearboxes and bearings, and replenish it promptly to the specified mark.
- Change the lubricating oil once a month, giving priority to the manufacturer‑recommended grade and avoiding mixing oils from different brands.
Sealing Inspection
- Inspect the lubrication system’s sealing rings for aging or damage to prevent dust and contaminants from entering and causing component wear.
III. Inspection of Critical Components
Screw and Barrel Wear Monitoring
- Conduct a monthly visual inspection to check the screw surface for scratches and the inner wall of the barrel for uniform wear; any abnormalities must be promptly repaired or replaced.
Mold temperature control
- Before production, verify that the mold heaters and cooling water circuits are functioning properly to prevent temperature fluctuations that could cause rubber scorching or defective molding.
IV. Process Parameter Adjustment
- Temperature and Pressure Optimization
- Adjust the barrel temperature according to the rubber type (typically maintained between 140 and 180°C) to prevent overheating, which can lead to material degradation.
- Regularly calibrate the pressure sensor to ensure stable extrusion pressure and prevent overload that could damage the motor or screw.
V. Maintenance Records and Preventive Maintenance
Establish a maintenance log
- Record each cleaning, lubrication, component replacement, and any abnormal occurrences to facilitate tracking equipment status and predicting potential failures.
Regular comprehensive maintenance
- Once per quarter, professional technicians perform a comprehensive maintenance service, which includes replacing worn components and calibrating the control system, among other tasks.
