The waste plastic extruder is a common equipment in the plastics processing industry, used to heat and extrude plastic raw materials into molds, which are commonly used to produce a variety of plastic products. However, in the long run, extrusion pelletizing machine may encounter some common failures. This article will introduce the common failures of waste plastic extruder and solutions to help users troubleshoot in a timely manner to ensure the stable operation of the equipment.
Abnormal Extrusion Temperature
- Possible causes: Heating system failure, inaccurate temperature control, etc.
- Solutions: Regularly check the heating system to ensure the normal operation of heating elements such as electric heaters and heating rings. Adjust the temperature control system according to the type of plastic and production requirements to keep the extrusion temperature stable.
Waste Plastic Extruder Barrel Clogging
- Possible causes: High humidity of plastic raw materials, excessive feeding, unreasonable feeding speed, etc.
- Solutions: Ensure that the plastic material is dry, to avoid excessive humidity leading to clogging of the barrel. Control the amount of feeding material to avoid overfeeding resulting in clogging of the barrel.
Inaccurate Product Sizes
- Possible causes: The die head is worn out. , poor extruder stability, etc.
- Solutions: Regularly check the die head and replace the screen in time to avoid any influence on the product size. Check the stability of the extrusion pelletizing machine to ensure a smooth extrusion process.
Noisy Extrusion Pelletizing Machine
- Possible causes: Loose transmission parts, poor lubrication, etc.
- Solutions: Check the transmission parts to ensure that the pulleys, gears, chains, etc. are tight and reliable. Add lubrication regularly to keep the transmission parts well-lubricated.
Waste Plastic Extruder Extrusion Instability
- Possible causes: Screw wear, unstable screw speed, etc.
- Solutions: Regularly check the screw condition and replace the worn screw in time. Check the transmission system of the extrusion pelletizing machine to ensure that the screw speed is stable.
Electrical Issues of Extrusion Pelletizing Machine
- Possible causes: Loose electrical connections, unstable power supply, etc.
- Solutions: Periodically check electrical connections to ensure they are secure. Check the power supply and troubleshoot power problems.
