Food packaging machine motor temperature is too high causes and solutions

In the process of packaging machine operation, the motor temperature is too high is a common but need to pay great attention to the problem. Excessive temperature will not only affect the normal operation of the equipment, but also may shorten the service life of the motor, and even cause safety hazards.

The following are the main causes of high temperature of the packaging machine motor and its solutions:

Packaging machine overload operation

Motor overload operation is one of the common causes of high temperature. If the mechanical belt is too tight or the shaft is not flexible, the motor will be overloaded for a long time, resulting in increased heat generation.

Solution:
1.Check and adjust the tightness of the packaging machine drive belt to ensure it is in a reasonable range.
2.Dismantle and check the mechanical equipment to make sure the shaft rotation is flexible.
3.Adjust the load so that the motor runs under the rated load, and avoid overloading for a long time.

High temperature working environment

The high temperature of the working environment of the motor will directly affect its heat dissipation performance. For example, vacuum packaging machine motors that are exposed to direct sunlight, or ambient temperatures exceeding 40°C, or poor ventilation will result in higher motor temperatures.

Solution:
1.Build a simple sunshade for the motor to avoid direct sunlight.
2.Improve the ventilation of the packer by using a blower or fan to enhance air circulation.
3.Regularly clean the oil and dust in the motor air duct to ensure that the heat dissipation channel is smooth.

Packaging machine bearing poor lubrication or stalling

Inadequate lubrication or dried out grease in the motor bearings will result in increased friction, which in turn will cause localized temperature increases. If the temperature in the bearing area is significantly higher than other parts, it may be a sign of poor lubrication.

Solution:
1.Regularly check the packaging machine bearing lubrication to ensure that the grease is in the right quantity and of good quality.
2.Replace aged or dried out grease and use lubrication products suitable for the motor’s operating conditions.
3.Check the bearings for damage and replace if necessary.

Ventilation system failure

A motor with a blocked ventilation system or a radiator that has accumulated too much dust can seriously affect heat dissipation. In addition, excessively thick grease may prevent ventilation from dissipating heat.

Solution:
1.Clean the air ducts and radiators of the packer regularly to ensure that the ventilation system is unobstructed.
2.Check the amount and condition of the grease to avoid over-thickness of grease affecting heat dissipation.
3.Use compressed air or special tools to remove dust and debris inside the motor.

Transmission system failure

Transmission system failure (such as gear wear, belt slippage, etc.) will lead to uneven loads on the motor, or even jamming, thus causing a sharp rise in temperature of the packaging machine motor. If not dealt with in time, it may lead to burning out of the windings.

Solution:
1.Regularly check the operating status of the packaging machine drive system and replace worn parts in a timely manner.
2.Ensure that the transmission belt is appropriately tightened to avoid over-tightening or over-loosening.
3.Lubricate and maintain the transmission system to reduce friction and heat generation.

Food packaging machine motor temperature is too high is a multi-factor problem. Through regular maintenance, reasonable adjustment of operating parameters and improve the working environment, can effectively reduce the motor temperature, extend the service life of the equipment, and ensure production safety. It is recommended that enterprises develop a detailed equipment maintenance plan and train professionals to regularly check and deal with potential problems to ensure the stable operation of the food production line.
