As the core equipment for quality inspection in the packaging materials and paper products industry, the stability of the edge compression testing machine directly affects the accuracy of the testing results. To ensure the long-term efficient operation of equipment, Kebao brand has developed a systematic maintenance plan based on years of technical experience, covering daily maintenance, regular repairs, and emergency response to faults, helping users reduce equipment failure rates and extend service life.

1、 Daily maintenance: Details determine reliability

Cleaning and dust prevention

After daily use, it is necessary to wipe the surface of the equipment and the testing table with a soft dry cloth to avoid the accumulation of dust and paper scraps that may affect the accuracy of the sensor. Especially, it is necessary to clean the residual samples in the gaps of the fixture to prevent hard objects from scratching the test surface. It is recommended to blow the internal cooling fan and circuit board area of the equipment with compressed air every week to prevent dust blockage and overheating.

Lubrication and transmission inspection

Apply special lubricating grease to transmission components such as linear guides and screw rods every month to ensure smooth and unobstructed movement of moving parts. At the same time, check the synchronous belt tension of the electric slider structure. If there is looseness or cracking, it should be replaced in a timely manner to avoid transmission errors affecting test data.

Electrical system inspection

Before starting up daily, check whether the power and grounding wires are loose, and confirm that the equipment casing is well grounded. Regularly use a multimeter to check the working power supply（AC220V）Stability, voltage fluctuations exceeding±5%It is necessary to install a voltage regulator.

2、 Regular maintenance: preventive maintenance to reduce risks

Quarterly in-depth maintenanceA comprehensive dismantling and inspection of the equipment is required every quarter, with a focus on:

Sensor calibration: Use standard weights to verify the accuracy of the load sensor, with errors exceeding±1%Need to return to the factory for adjustment;

Fixture wear detection: Check the degree of wear of the testing pressure plate and edge positioning block, and replace the customized fixture if necessary;

Mechanical structure fastening: Check whether the equipment feet and transmission shaft fixing screws are loose to prevent resonance during operation.

Annual major overhaulEvery year, professional engineers disassemble the entire machine, replace aging sealing rings, bearings, and other vulnerable parts, and perform dust removal and component solder joint inspection on the control circuit board. Simultaneously upgrade the firmware program and optimize the device's operational logic.

3、 Emergency handling of faults: rapid response to ensure production

Common troubleshooting

Abnormal conductivity count: Check if the conductivity line is broken and clean the oxide layer at the contact point of the test head;

Speed fluctuation: calibrate the rotary encoder or replace the electric slider drive module;

Data jump: Restart the device and check the grounding wire. If the problem persists, replace the motherboard.

Suggestions for spare parts reserveSuggest users to stock up on commonly used spare parts (such as load weights, conductive wires, synchronous belts) and keep them in Kebao24Hourly technical service hotline to ensure that any malfunctions occur48Complete repairs within hours.

4、 Maintain records and archive management

Establish an equipment maintenance ledger to record the time of each maintenance, replacement of parts, and calibration data. Through data analysis, the lifespan of the equipment can be predicted in advance. For example, if the sensor error increases linearly after three consecutive calibrations, it is necessary to plan for replacement.

Conclusion

The maintenance of Kebao edge pressure testing machine should follow the following guidelines“Prevention oriented, precise maintenance”The principle is that through daily cleaning, regular maintenance, and data-driven management, the equipment failure rate can be significantly reduced, ensuring the traceability and repeatability of testing results. Kebao provides lifelong maintenance services and customized maintenance packages to help users maximize the full lifecycle value of quality inspection equipment.
