In temperature-sensitive industries such as food and medicine, packaging machine temperature controllers are core components to ensure sealing strength and material stability. If the temperature controller fails, it may lead to problems such as loose sealing, deterioration of raw materials or equipment shutdown. In response to this common fault, XX Factory combined industry experience to summarize a systematic solution to help companies quickly resume production and reduce losses.
Common causes of temperature controller failure
Failure of packaging machine temperature controllers is usually caused by the following three types of problems:
Abnormal sensor signal: The temperature sensor probe is fouled or aged, resulting in signal transmission distortion;
Circuit system failure: Power supply fluctuations, poor line contact or damage to control board components;
Environmental interference: High temperature, dust or humid environment affects the stability of internal components of the temperature controller.
Four-step troubleshooting method: solve the problem layer by layer from the basics to the core
Step 1: Cleaning and calibration
Turn off the power of the equipment, disassemble the temperature controller housing, and use a soft brush to clean the residue on the surface of the sensor probe (such as plastic chips, colloids, etc.);
Use a special calibration tool to calibrate the temperature sensor to zero point and eliminate signal drift errors.
Step 2: Circuit detection
Check whether the power line is loose and measure whether the input voltage is within the rated range of the temperature controller;
Check whether the control board capacitors, relays and other components are burned or rusted, and replace damaged parts if necessary.
Step 3: Environmental optimization
Install a cooling fan or heat shield for the packaging machine in the high-temperature workshop to ensure that the working environment temperature of the temperature controller is lower than the general industry standard;
Regularly clean the dust around the equipment to avoid entering the temperature controller and causing a short circuit.
Step 4: System upgrade
Upgrade the anti-interference module for old models with frequent temperature controller failures to enhance circuit stability;
Replace the mechanical temperature controller with a digital intelligent model to support real-time temperature curve monitoring and abnormal warning.
Long-term prevention: Establish standardized maintenance procedures
Daily inspection: Operators record the deviation between the temperature displayed by the temperature controller and the actual sealing temperature every day, and report any abnormality immediately;
Periodic maintenance: Deeply clean and calibrate the packaging machine temperature controller every quarter, and replace the aging sealing rubber ring;
Operation training: Standardize the equipment start-stop process to avoid damage to the temperature controller caused by instantaneous current shock.
Conclusion
Although the failure of the packaging machine temperature controller is a common fault, the probability of occurrence can be greatly reduced through scientific troubleshooting steps and prevention mechanisms. Ply-pack factory recommends that enterprises customize maintenance plans based on equipment usage scenarios, and contact professional teams for systematic upgrades when necessary to ensure production continuity.
