Operating a corrugated roofing roll forming machine primarily involves ensuring stable equipment operation and product quality. The following are the key steps and precautions:
1. Pre-startup Inspection
Glue Check: Confirm that the glue tank has sufficient glue, and check for blockages in the glue delivery pipes to prevent insufficient glue or leakage affecting the bonding effect.
Equipment Status: Check the wear of the synchronous belt, ensure proper lubrication of the drive shaft, and verify that the air compressor pressure is normal. Fill out the inspection checklist.
Steam System: Check for leaks in the steam pipes and ensure the pressure is within the set range to guarantee stable heating.
2. Machine Operation Test
Function Test: Start the main machine, pressure roller, corrugated roller, glue roller, and blower in sequence. Observe whether each component is operating normally and whether the instrument pointers are accurate.
Emergency Test: Test the emergency stop button to ensure the equipment can stop immediately for safety.
3. Equipment Gap Adjustment
Gap Calibration: Use 0.1mm thick double-sided adhesive backing paper to adjust the gap between the corrugated roller and the glue roller to the minimum, ensuring consistent tension on both sides to prevent uneven corrugated formation.
4. Raw Paper Inspection
Quality Control: Check the flatness and tension of the raw paper to ensure it can pass smoothly through the preheater and corrugated roller, avoiding production interruptions or product quality defects due to raw paper problems.
5. Production Monitoring
Parameter Observation: Closely monitor parameters such as pressure, temperature, and speed, ensuring they are within the process requirements, and adjust them promptly to cope with production fluctuations.
Quality Inspection: Regularly check the corrugated cardboard's flute type, bonding strength, thickness, and other indicators to ensure compliance with standards.
Safety Precautions
Always wear protective equipment during operation to avoid contact with high-temperature components and glue, preventing burns or chemical injuries.
If the equipment malfunctions or breaks down, immediately stop the machine and notify maintenance personnel for repair. Do not operate the machine with a fault.
