Applicable equipment: All production line equipment (extruders, stretching machines, glue sprayers, hot presses, cutting machines, etc.).

Maintenance content:

Cleaning:

Remove aluminum shavings, adhesive stains, plastic particles, and other debris from the surface of the equipment and workbench (such as using a brush or compressed air for cleaning).

Focus on cleaning areas that are prone to material accumulation, such as the feed inlet of the extruder, the pin mechanism of the honeycomb core stretching machine, and the area around the glue nozzle of the glue spraying machine.

Lubrication:

Add lubricating oil (such as guide oil) to moving parts such as linear guides and ball screws to ensure smooth operation (according to the oil type and dosage specified in the equipment manual).

Apply a small amount of lubricating grease to pneumatic components (such as cylinder guides) to prevent rusting.

Check:

Before starting up, check if all instruments (temperature, pressure, speed) are normal, and test run the equipment to observe for any abnormal noise, vibration, or jamming.

Check if the pneumatic system pressure is stable (such as the pressure gauge showing 0.4-0.6MPa), and if there are any signs of oil leakage in the hydraulic system.

The cutting equipment needs to check whether the tool installation is firm and whether the saw blade has cracks or excessive wear.

2、 Weekly maintenance (every 50-60 hours of operation time)

Applicable equipment: core equipment such as extruders, stretching machines, hot presses, hydraulic systems, etc.

Maintenance content:

Deep cleaning:

Extruder: Rinse the screw and barrel with cleaning material to remove residual materials (to avoid carbonization of materials after shutdown).

Glue spraying machine: Disassemble the glue nozzle and pipeline, thoroughly clean with specialized solvents (such as alcohol, acetone) to prevent glue from solidifying and blocking.

Hot press machine: Wipe the surface of the hot press plate, remove glue stains and debris, and avoid affecting the bonding accuracy of the board.

Lubrication and fastening:

Add lubricating grease to the gearbox and motor bearings (according to the equipment manual cycle, the lubricating oil is usually replaced every 2000 hours of operation, but the oil level needs to be checked weekly).

Check whether the bolts and nuts in various parts of the equipment are loose (such as the fixing bolts of the stretching machine guide rail and the screws of the cutting machine transmission mechanism).

Functional testing:

Calibrate the glue measuring system of the glue machine to ensure accurate AB glue mixing ratio (error ≤± 1%).

Test the temperature uniformity of the temperature control system of the hot press machine (temperature difference should be ≤± 5 ℃), and if there is any abnormality, check the heating tube or temperature control module.

3、 Monthly maintenance (every 200-250 hours of operation time)

Applicable equipment: extruders, stretching machines, hydraulic systems, electrical control systems, etc.

Maintenance content:

Mechanical component inspection:

Extruder: Disassemble the screw, check for wear (such as surface roughness of threads, scratches), and grind or replace if necessary.

Honeycomb core stretching machine: Check the positioning accuracy and wear degree of the stretching mold, adjust the mold gap to ensure consistent honeycomb core size.

Cutting machine: Check the wear of the cutting tool (if the thickness wear of the saw blade exceeds 2mm, it needs to be replaced), calibrate the cutting size accuracy (error ≤± 0.5mm).

System maintenance:

Hydraulic system: Replace the hydraulic oil filter element, check the oil contamination level (should be controlled within NAS8 level), and replace all if the oil is emulsified or contains too many impurities.

Pneumatic system: Clean the air cylinder and oil-water separator of the air compressor, check whether the solenoid valve is sensitive, and replace the aging air pipe or sealing ring.

Electrical system:

Clean the dust inside the electrical cabinet, check if the wiring terminals are loose, and test the insulation resistance of the motor (which should be ≥ 0.5M Ω).

Backup PLC programs and touch screen parameters to prevent data loss.

4、 Quarterly maintenance (every 600-750 hours of operation)

Applicable equipment: transmission system, heating/cooling system, complex pneumatic/hydraulic equipment.

Maintenance content:

Maintenance of transmission system:

Gearbox: Replace the gear oil (usually every 2000 hours of operation, and during quarterly maintenance, it can be decided whether to replace it in advance based on the oil quality test results).

Chain/belt drive: Check the tension and wear of the chain, clean the oil stains on the chain, and apply lubricating grease; If the belt cracks or slips, adjust the tension or replace it.

Heating/cooling system:

Hot press machine: Check the aging condition of heating tubes (such as electric heating tubes and thermal oil pipelines), and test whether the heating rate in each temperature zone meets the standard.

Cooling system: Clean the cooler (such as water-cooled radiator, oil cooler), remove scale or impurities, and ensure heat dissipation efficiency.

Precision component calibration:

Honeycomb core stretching machine: Calibrate the stretching speed and stroke accuracy, and detect the edge length error of the stretched honeycomb core through sensors (should be ≤± 0.2mm).

Automatic glue spraying machine: Verify the sensitivity of the glue sensor, adjust the glue pressure to ensure the uniformity of glue application.

5、 Annual maintenance (every 2000-3000 operating hours)

Applicable equipment: Full production line equipment, focusing on large units and precision components.

Maintenance content:

Comprehensive disassembly inspection:

Extruder: Thoroughly disassemble the screw and barrel, perform non-destructive testing (such as ultrasonic testing), repair or replace severely worn components.

Hot press machine: Check the hydraulic cylinder seals (such as O-rings and piston rod oil seals). If they are aging or damaged, replace them all and recalibrate the pressure parameters.

Honeycomb core stretching machine: detects the straightness and perpendicularity of the guide rail (error ≤ 0.1mm/m), and if necessary, grinds or replaces the guide rail.

System performance upgrade:

Electrical control system: Update PLC program or touch screen software to optimize equipment operating parameters (such as extruder screw speed, hot press holding time).

Pneumatic/Hydraulic System: Conduct overall inspection of pipeline sealing, replace air pipes and hydraulic hoses that have been in use for more than 3 years to avoid aging and bursting.

The honeycomb core material is the core part of the honeycomb panel, and its molding process directly affects the performance of the honeycomb panel. The main equipment includes: honeycomb core material forming machine: raw materials (such as aluminum foil, paper, etc.) are made into honeycomb structures through continuous folding, bonding, cutting and other processes. Forming machines typically include feeding devices, folding devices, bonding devices, and cutting devices. Hot press machine: used for hot pressing composite of honeycomb core material and panel. A hot press machine uses heating and pressure to quickly cure the adhesive, ensuring a strong bond between the core material and the panel. The temperature and pressure of the hot press machine need to be precisely controlled according to material and process requirements.

After the formation of honeycomb panels, a series of post-processing is required, including cutting machines that cut the honeycomb panels into the required size and shape. Grinding machine: Polish the edges of the honeycomb board to ensure it is smooth and even. Surface treatment equipment: such as spraying machines, laminating machines, etc., for decorating or protecting the surface of honeycomb panels. Modern honeycomb panel production lines are usually equipped with automation control systems, including PLC (Programmable Logic Controller), sensors, human-machine interfaces, etc., to achieve automation and intelligent control of the production process, improve production efficiency and product quality.
