After the onset of autumn, the temperature gradually drops, the air humidity decreases, and the temperature difference between day and night increases. The polypropylene spinning machine is prone to various operational abnormalities, which affect the continuity of production and the quality of the fiber products. During the transition of seasons, the workshop should conduct targeted inspections for equipment hazards and reduce the risk of shutdowns. Now, from the five aspects of temperature, humidity, transmission, electricity, and operation, the key maintenance matters during the seasonal transition are as follows.

1. Abnormalities caused by temperature fluctuations

The temperature difference between day and night is large in autumn. If the workshop temperature is not adjusted in time, the load of the heating system of the spinning unit will change accordingly. When the temperature in each area of the screw extruder deviates, the melt flowability is affected, and it is easy to cause uneven filament thickness. During the seasonal transition, the inspection of temperature control instruments should be strengthened, and the heating power should be adjusted in a timely manner according to the environmental temperature to ensure that the temperature in each range is within the process setting. It is recommended to clearly define the allowable deviation of each temperature zone (such as ±1℃) in the equipment manual and set the alarm threshold accordingly to facilitate the timely detection of abnormalities.

2. Impact of humidity changes

In autumn, the air becomes drier, and the relative humidity decreases. After that, the static electricity phenomenon in the spinning process becomes more severe, and the filament is prone to get tangled on the guide roller and during the winding process. Appropriate humidification equipment can be configured in the workshop to maintain the relative humidity within a reasonable range (generally recommended to control it at 50% to 65%). At the same time, check whether the grounding of each guide component is good to reduce static accumulation.

3. Maintenance points for transmission components

After the temperature drops, the viscosity of the lubricating oil increases, and the operating resistance of the transmission parts such as the winding machine and the stretching roller increases accordingly. If the lubrication is not adequate, the wear rate of the bearings will accelerate. During daily work, it is recommended to add the appropriate brand of lubricating grease according to the maintenance plan regularly. The brand can be determined based on the equipment manual or the manufacturer's recommendation; at the same time, listen to the running sound to detect any abnormal noise and stop the machine for troubleshooting in time.

4. Inspection of electrical components

In autumn, there is a lot of dust, and the internal parts of the frequency converter and contactors are prone to accumulate dust, resulting in a decrease in heat dissipation efficiency and possible overheating protection actions. During the downtime, the electrical control cabinet can be cleaned by blowing, and check whether the connection terminals are loose to ensure that the cooling fan is running normally. Before blowing, it is necessary to confirm that the equipment is powered off and take anti-static measures to avoid dust flying and causing safety hazards.

5. Precautions at the operational level

During the seasonal transition, team members should appropriately increase the inspection frequency and pay special attention to the changes in parameters such as melt pressure and filament tension. When abnormal fluctuations are detected, gradually troubleshoot according to the operating procedures to avoid blindly adjusting process parameters. At the same time, keep good records of equipment operation to provide reference for subsequent maintenance.

In summary, the faults of the polypropylene spinning machine in autumn are mostly related to environmental changes. By strengthening temperature and humidity management, implementing lubrication maintenance, and conducting electrical cleaning, the probability of faults can be effectively reduced, and production can be carried out smoothly.
