The human-machine interface usually uses touch screens or industrial computers.

What maintenance is required for honeycomb panel production line equipment?

1、 Key points for maintenance of core equipment

1. Extruder (plastic honeycomb board production line)

Screw and barrel:

Regularly clean the residual materials in the screw and barrel to avoid carbonization or degradation of the materials (especially before shutdown, rinse with cleaning materials).

Check the wear of the screw. If there are scratches or thread deformations, they should be repaired or replaced in a timely manner to ensure even plasticization.

Transmission system:

The oil level and temperature of the gearbox need to be checked regularly, and the lubricating oil should be replaced periodically (usually every 2000 hours of operation) to avoid gear wear or overheating.

Regularly add lubricating grease to the motor bearings to prevent abnormal noise or jamming caused by insufficient lubrication.

2. Honeycomb core stretching machine (aluminum honeycomb panel production line)

Stretch mold and guide rail:

Clean the aluminum shavings and adhesive stains on the surface of the mold every day to avoid impurities affecting the dimensional accuracy of the honeycomb core.

The guide rail and slider need to be regularly coated with lubricating oil (such as lithium grease) to ensure smooth movement of moving parts and reduce wear.

Pneumatic system:

Check the sealing of the cylinder. If air leakage or slow movement is found, replace the sealing ring or repair the cylinder.

Air filters should be regularly drained and cleaned to prevent moisture and impurities from entering the air path and affecting equipment operation.

3. Automatic glue spraying machine

Rubber pump and pipeline:

Clean the glue pump and pipeline promptly after each use (especially when changing the glue type) to prevent the glue from solidifying and blocking the channel.

Regularly check the wear of the sealing components of the glue pump, and replace the sealing ring immediately if there is glue leakage.

Measurement system:

Calibrate the adhesive ratio sensor to ensure the accuracy of AB adhesive mixing (recommended once a week), and avoid poor adhesion caused by ratio deviation.

4. Hot press/cold press machine

Heating system:

Regularly check the temperature uniformity of the hot press plate (using a thermometer), and if the temperature difference exceeds ± 5 ℃, check the heating tube or temperature control module.

Heating elements (such as electric heating tubes and thermal oil pipelines) should be regularly inspected for aging or leakage risks, and damaged parts should be replaced in a timely manner.

Hydraulic system:

Hydraulic oil should be filtered and replaced regularly (usually every six months), and the oil contamination level should be controlled within NAS8 level.

Check the sealing components of the hydraulic cylinder to avoid oil leakage that may cause unstable pressure or insufficient plate pressing.

5. Cutting equipment (trimming saw, CNC cutting machine)

Cutting tools and saw blades:

Clean the adhesive stains and aluminum shavings on the cutting tool after each use, and grind it regularly (usually every 5000 meters according to the cutting amount) to ensure a smooth and burr free cut.

Check the installation accuracy of the saw blade. If there is vibration or cutting deviation, recalibrate or replace the saw blade.

Transmission mechanism:

Lubricate the ball screw and linear guide rail daily, remove debris from the guide rail, and prevent jamming from affecting cutting accuracy.

6. Pneumatic/Hydraulic Equipment

Pneumatic components:

Regularly check the sensitivity of the pressure reducing valve and solenoid valve, remove impurities from the valve core, and avoid equipment shutdown caused by gas path failures.

Hydraulic components:

Regularly check the pressure setting of overflow valves and directional valves to ensure stable system pressure and prevent damage to plates or equipment due to abnormal pressure.

2、 General maintenance principles

1. Cleaning management

After daily production, clean the surface of the equipment and workbench of aluminum shavings, glue stains, plastic particles, and other debris to avoid entering the transmission components or affecting sensor accuracy.

Regularly (weekly) conduct deep cleaning of the internal parts of the equipment, such as the pin mechanism of the honeycomb core stretching machine and the feed inlet of the extruder, which are prone to material accumulation.

2. Lubrication management

Establish a lubrication ledger for equipment, specifying the refueling cycle, oil type, and dosage for each lubrication point (such as using 32 # rail oil for guide rails and 150 # industrial gear oil for gearboxes).

Adopting the "five fixed" principle: fixed point, fixed time, fixed quality, fixed quantity, and fixed personnel, to avoid leakage or excessive lubrication.

3. Electrical and Control Systems

Check the wiring terminals inside the electrical cabinet weekly for looseness, clean the dust to prevent short circuits (compressed air can be used for blowing).

Regularly backup programs for control systems (such as PLC, touch screen) to prevent data loss; Check the sensitivity of sensors (such as photoelectric switches and pressure sensors) to ensure accurate signal transmission.

4. Replacement of vulnerable parts

Establish a vulnerable parts inventory (such as seals, bearings, heating tubes, cutting tools, etc.), replace them in advance according to their usage cycle, and avoid sudden shutdowns.

Record the replacement time of vulnerable parts, such as checking the wear of the pins of the honeycomb core stretching machine every 10000 uses, and replacing the sealing ring every 3000 hours of operation.

5. Regular inspections and fault prediction

Before starting up daily, conduct a trial operation check to listen for any abnormal sounds (such as noise or vibration) from the equipment, and observe if the instrument parameters (pressure, temperature, speed) are within the normal range.

Conduct a comprehensive inspection once a month to test the accuracy of the equipment (such as the thickness tolerance of the honeycomb board and the edge length error of the honeycomb core), and predict potential faults through trend analysis (such as the gradual increase in cutting deviation caused by rail wear).

3、 Seasonal maintenance points

Summer high temperature:

Strengthen the cooling of the hydraulic system and motor, regularly clean the cooler, ensure that the oil temperature does not exceed 55 ℃, and prevent oil deterioration.

Increase the drainage frequency of the pneumatic system to avoid excessive condensation affecting component performance.

Winter low temperature:

Drain the accumulated water in the cooling water circuit before shutdown to prevent pipeline freezing and cracking; Replace the hydraulic oil with a low viscosity model (such as using 46 # anti-wear hydraulic oil in winter).

After a long shutdown, it is necessary to preheat the equipment (such as running the hot press for 15 minutes) before loading it for production.

Honeycomb board is a lightweight, high-strength composite material widely used in fields such as construction, transportation, aerospace, etc. Its core structure is a honeycomb core material, usually made of materials such as aluminum, paper, plastic, etc., covered with panels on both sides (such as aluminum plates, steel plates, fiberglass, etc.), and composite by adhesive or hot pressing process. The production of honeycomb panels requires a series of specialized equipment that work together to complete the entire process from raw materials to finished products.

Honeycomb panels are widely used in building curtain walls, partition walls, ceilings, and other parts. Their lightweight and high-strength characteristics can effectively reduce building loads, while also having good sound insulation and thermal insulation effects. In the fields of automobiles, high-speed trains, ships, etc., honeycomb panels are used to manufacture body, floor, interior and other components, which can reduce vehicle weight and improve fuel efficiency.
