Phenomenon: The stretched mesh exhibits uneven thickness and varying hole sizes.

Troubleshooting method:

Check if the stretching rollers are parallel and if the gaps are consistent.

Check if the temperature of the heating system is uniform and if the heating elements are damaged.

Check whether the quality of the raw materials is qualified and whether there are impurities or bubbles.

2. Network disconnection:

Phenomenon: Breakage occurs during the stretching process.

Troubleshooting method:

Check if the stretching speed is too fast and if the stretching ratio is too large.

Check whether the quality of the raw materials is qualified and whether there are impurities or bubbles.

Check whether the surface of the stretching roller is smooth and whether there are burrs or scratches.

3. Network defects:

Phenomenon: Defects such as bubbles, impurities, scratches, etc. appear on the surface of the stretched mesh.

Troubleshooting method:

Check whether the quality of the raw materials is qualified and whether there are impurities or bubbles.

Check if the temperature of the heating system is too high, causing the decomposition of raw materials.

Check if the surface of the stretching roller is clean and if there are any foreign objects.

4. Equipment abnormal noise:

Phenomenon: Abnormal noise occurs during the operation of the equipment.

Troubleshooting method:

Check if the bearings are damaged and if the lubrication is good.

Check if the drive belt is loose or worn.

Check if the mechanical components are loose or deformed.

3、 Equipment shutdown fault

1. Emergency shutdown:

Phenomenon: The device suddenly shuts down during operation.

Troubleshooting method:

Check if the emergency stop button has been pressed.

Check if the safety protection devices are activated, such as overload protection, temperature protection, etc.

Check if the power supply suddenly interrupts.

2. Program shutdown:

Phenomenon: The device shuts down according to the preset program.

Troubleshooting method:

Check if the program settings are correct, such as production quantity, time, etc.

Check if the sensors are working properly, such as position sensors, temperature sensors, etc.

Check if the PLC program is running properly.

4、 Other faults

1. Equipment oil leakage:

Phenomenon: Lubricating oil leakage occurs in the equipment.

Troubleshooting method:

Check if the oil seal is damaged and if the sealing ring is aging.

Check if the oil circuit is blocked and if the oil pressure is too high.

2. Equipment overheating:

Phenomenon: Local or overall temperature of the equipment is too high.

Troubleshooting method:

Check if the cooling system is working properly, such as fans, water pumps, etc.

Check if the lubrication is good and if there is any dry friction.

Check if the equipment load is too high and if there is overload operation.

5、 Precautions for troubleshooting

1. Safety first: Before conducting any troubleshooting, it is essential to ensure that the equipment has been powered off and necessary safety measures have been taken.

2. Careful observation: Carefully observe the fault phenomenon and record relevant information, such as the time, phenomenon, location, etc. of the fault occurrence.

3. Step by step investigation: From simple to complex, gradually investigate the cause of the malfunction and avoid blindly disassembling the equipment.

4. Seek help: If you are unable to troubleshoot on your own, you should promptly contact the equipment manufacturer or professional maintenance personnel.

6、 Preventive maintenance

To avoid equipment failures, it is recommended to conduct regular preventive maintenance, including:

Regular inspection: Regularly check the working status of various components of the equipment, such as bearings, drive belts, oil seals, etc.

Regular lubrication: Regularly lubricate the equipment to ensure that all moving parts are well lubricated.

Regular cleaning: Regularly clean the surface and interior of the equipment to prevent dust and foreign objects from accumulating.

Regular calibration: Regularly calibrate equipment sensors and control systems to ensure their accuracy and reliability.

Through the above troubleshooting methods and preventive maintenance measures, the operational stability and production efficiency of the biaxially stretched mesh production line equipment can be effectively improved, the equipment failure rate can be reduced, and product quality can be guaranteed.
