Daily Maintenance Guidelines for Honeycomb Panel Production Line

The honeycomb panel production line integrates uncoiling, gluing, laminating, hot pressing, cutting and stacking. Stable equipment operation ensures product quality, efficiency and cost control. Daily maintenance shall follow the principles of prevention-first, precise maintenance and safety priority.

1. Daily Maintenance of Core Equipment

1.1 Uncoiling & Leveling Unit

Pre-shift check: Verify stable reel shaft pressure (0.4-0.6MPa), sheet alignment, scratch-free leveling rollers and proper feeding belt tension without deviation.

In-shift inspection: Monitor abnormal noises and flat sheet surface; adjust tension or clean roller surface if slipping occurs.

Post-shift maintenance: Clean rollers with neutral detergent; lubricate bearings and drive chains with lithium grease weekly; regularly inspect shaft seals against air leakage.

1.2 Gluing & Laminating Unit

Pre-shift preparation: Adjust glue viscosity (200-300mPa·s) and pump pressure (0.3-0.5MPa); set glue roller gap per sheet thickness, keep rollers free from glue buildup and wear.

In-shift monitoring: Ensure even gluing and proper laminating pressure; shut down and flush blocked pipes timely.

Post-shift cleaning: Thoroughly clean glue rollers, pipes and tanks to avoid glue solidification; replace tank filters weekly and check pump seals for leakage.

1.3 Hot Press Forming Unit

Pre-shift check: Confirm heating plate temperature (120-150℃, tolerance ±5℃) and normal hydraulic pressure (1.5-2.0MPa) without oil leakage; inspect seal pads.

In-shift inspection: Check abnormal vibration and uniform temperature distribution; adjust parameters once sheet blistering occurs.

Regular upkeep: Remove residual glue on heating plates weekly; replenish hydraulic oil and replace filters monthly; test and renew aging heating tubes quarterly.

1.4 Cutting & Stacking Unit

Pre-shift check: Ensure sharp cutting blades with dimensional error ≤±1mm; confirm suction cup vacuum degree ≥-0.08MPa and smooth manipulator movement.

In-shift monitoring: Check neat cutting edges and tidy stacking; clean suction cups or inspect vacuum system for poor adsorption.

Regular maintenance: Lubricate cutting machine guide rails monthly and adjust belt tightness; replace suction cups and calibrate sensors quarterly.

2. General Maintenance Rules

Daily Inspection: Operators conduct 15-minute pre-shift check on power supply, safety devices and lubrication points with records kept.

Cleaning Management: Remove scraps and dust after shift; perform deep cleaning weekly for heat dissipation.

Lubrication Management: Establish lubrication records and refill specified oil regularly to reduce component wear.

Troubleshooting: Stop operation immediately upon abnormalities and report faults; record relevant data for preventive maintenance.

3. Safety Maintenance Notes

Standard Operation: Forbid irregular operations and crossing safety fences during operation.

Maintenance Safety: Cut off power and hang warning signs before repair; wear protective gear during work.

Emergency Handling: Conduct regular safety training; equip fire-fighting and first-aid supplies for rapid emergency response.

Conclusion

Closed-loop management including pre-shift inspection, in-shift monitoring and post-shift maintenance can lower failure rate and extend equipment service life. Standardized operation and strict safety management guarantee steady production and economic benefits.
