As the core equipment for suppository production, the stable operation of the fully automatic suppository continuous production line is directly related to product quality and production efficiency. In the actual production process, various malfunctions often occur due to factors such as raw material characteristics, equipment wear, and operating standards. Below, the editor will briefly introduce the common faults and solutions of the fully automatic suppository continuous production line:
1. Sealing system malfunction
Fault manifestations: unstable infusion volume, loose sealing, or aluminum foil deviation.
Solution: Check whether the piston adjustment of the infusion pump is accurate, ensure that the needle is installed firmly and lubricated sufficiently; Adjust the tension and sealing temperature of the aluminum foil (horizontal sealing 150-165 ℃, vertical sealing 150-170 ℃), and clean the dirt on the surface of the sensor.
2. Abnormal control system
Fault manifestations: PLC program errors, communication interruptions, or instruction delays.
Solution: Restart the PLC and check the program logic, fix the communication line connection problem; If it is an environmental factor (such as high temperature), it is necessary to optimize the cooling system and control the temperature and humidity in the workshop.
3. Wear and tear of mechanical components
Fault manifestations: broken drive belt, abnormal bearing noise, or stuck stamped parts.
Solution: Regularly replace lubricating oil, check the tightness of the transmission belt and the condition of the bearings; Severely worn components need to be replaced in a timely manner and ensure that the equipment is installed securely.
4. Misdetection or failure of sensors
Fault manifestation: Material position detection error, abnormal speed feedback.
Solution: Clean the sensor surface and adjust the sensitivity threshold; Check if the power connection is stable and replace the faulty sensor if necessary.
5. Environmental and Cleanliness Issues
Fault manifestation: Dust pollution leads to unclean sealing or poor heat dissipation of equipment.
Solution: Maintain the cleanliness of the sealing area (with a medication level of no less than 100000 for the cavity), and regularly clean the equipment dust; Check the water level of the circulating water tank and the operating status of the cooling system.
6. Electrical malfunction
Fault manifestations: Motor stalling, power fluctuation, or cable short circuit.
Solution: Check the stability of the power supply voltage and tighten the cable joints; When the overload protection is triggered, the load condition needs to be checked and reset.
The above faults need to be prevented through regular maintenance (such as lubrication and cleaning) and real-time monitoring (such as sensor calibration).
