Routine Maintenance Of Medium Density Fiberboard Splicing Machine

The daily maintenance of the medium-density fiberboard gluing machine should be carried out comprehensively from four aspects: mechanical, electrical, environmental protection and operation specification, in order to ensure the stability of equipment performance, prolong service life and guarantee the gluing quality. Specific points of maintenance are as follows:

I. Maintenance of Mechanical Components
Transmission System Inspections
Check the wear and tear of chain, transmission belts, gear, etc., and replace the aging or damaged parts in a timely manner.
The transmission system (X/Y/Z three axes) is lubricated weekly, using lubricant that matches the frequency of the equipment to avoid overthickness or thinness affecting operational efficiency.
Regularly clean the dust from the sawdust and transmission components to prevent blockage or overheating.
Pressure System Calibration
Check pressure sensors and pressure pumps regularly to ensure that pressure values are stable and meet wood assembly requirements (for example, hardwood requires larger pressure).
Avoid loose assembly due to wood damage or low pressure due to excessive pressure.
Replacement of Wearable Parts
Periodically inspect parts such as seals, bearings, scrapers, etc., which are easy to wear out, and replace them in a timely manner according to the degree of wear, so as to prevent breakdowns caused by the ageing of the components.

II. Electrical system maintenance
Circuit and control panel Inspections
Check the circuit connections is loose once a month to prevent faulty contact from causing equipment to shut down or malfunction.
Clean the inside of control panel and electrical box to prevent dust or wood chips from entering and causing short circuit.
Safety device testing
Regularly test overload protectors, emergency stop switches, etc., to ensure a timely response in the event of failure.
Avoid exposing electrical systems to humidity or heat to prevent component damage.

III. Environmental controls
Temperature and Humidity Management
The working environment temperature is kept within 18-25°C and relative humidity within 40-60%. This prevents dry shrinkage and wet swelling of the wood, thus avoiding jointing problems.
Avoid exposing equipment to humidity or high temperatures to prevent metal components from rusting or damaging electronic components.
Cleaning and ventilation
Wash wood chips and dust from equipment surfaces daily, especially ventilation ports and cooling systems, to prevent blockages and affect heat dissipation.
Clean dust collection system regularly to ensure wood dust concentration ≤ 1mg/m3 meets environmental protection requirements.

IV. INTRODUCTION Operating procedures and training
Operator training
Ensure that operators are professionally trained and familiar with equipment operating procedures and safety requirements (such as prohibiting the use of gloves during operations and avoiding unloaded operations).
During operation, focus should be maintained to prevent equipment damage or personal injury due to improper operation.
Pre-operation Inspection
Before starting, check the lubrication and tightness of each component of the equipment and adjust the roller or pressure parameters according to the thickness of the plate.
Ensure that the surface of the wood connector is dry, with no dead angle and even thickness (can be processed with a high-grade planer).
Repairs during lockdown
When the equipment is closed for a long period of time, the transmission system should be lubricated weekly and left idle to prevent components from rusting or clogging.
After stopping, loosen the roller, remove the the workpiece and backing plate to avoid deforming the equipment.

V. Lubrication and oil management
Hydraulic Oil Maintenance
Wash, filter or replace the hydraulic fluid in the oil tank regularly. When oil levels are low, add more oil.
Use standard hydraulic oil (such as 90-grade gear oil) to prevent impurities from entering the oil circuit system.
Cooling System Maintenance
Ensure that the cooling water is clean and the water pump works properly to prevent the water-cooled spindle motor from overheating due to lack of water.
Replace cooling water regularly to avoid excessive water temperature affecting equipment performance.

VI. INTRODUCTION Special Maintenance of High-frequency Gluing Machine
Print cleaning
Periodically remove impurities and residuals from the plate, especially iron filings and metals, to prevent the plate from burning.
Do not use wood padding thicker than plywood to avoid damaging the plywood.
