Waste plastic granulator is a common plastic processing equipment that heats and melts plastic, and then extrudes them into various shapes of plastic products. However, during the use process, sometimes there may be broken bars, leading to a decrease in production efficiency and even affecting product quality. This article will introduce the causes of broken plastic film granulator and corresponding solutions to help solve this common problem.
Reasons for Broken Strips in Waste Plastic Granulator
Unstable temperature
The temperature of the plastic film granulator is a key factor affecting the extrusion quality. High or low temperatures can cause broken bars. Excessive temperature may cause overheating of the melt, particle decomposition, and generation of bubbles and foreign objects, leading to breakage of the strip. If the temperature is too low, it will lead to an increase in melt viscosity, poor extrusion, and easy occurrence of breakage.
Screw and Barrel Wear
The screw and barrel are the core components of a waste plastic granulator, and their wear level directly affects the extrusion effect. If the screw or barrel is severely worn, the plastic cannot be heated enough, leading to unstable extrusion and resulting in broken bars.
Excessive Extrusion Speed
Extrusion speed refers to the speed at which plastic is extruded from inside the plastic film granulator. The extrusion speed of the plastic pelletizing extruder is too fast, which may lead to unstable particle extrusion and easy breakage of the bars.
Solutions for Broken Strips in Plastic Pelletizing Extruder
Adjustment of Temperature
Adjust the temperature parameters of the waste plastic granualtor according to the type and requirements of plastic. Ensure that the temperature is stable within the appropriate range, avoid being too high or too low, and maintain the quality of the extruded products.
Regular Maintenance
Regularly check the wear of the screws and barrel, and replace them promptly if necessary. Maintain the good condition of the screw and barrel to ensure that the material is fully heated and stably extruded.
Adjustment of Waste Plastic Granulator Temperature
Adjust the temperature parameters of the plastic pelletizing extruder according to the characteristics and requirements of the material.
Conclusion:
The problem of broken bars in waste plastic granulator may be caused by various factors, but by analyzing the causes and adopting corresponding solutions, the problem of broken bars can be effectively prevented and solved. Regular maintenance of equipment, maintaining temperature stability, and adjusting extrusion speed are important measures to ensure stable extrusion production. As long as the operating procedures are strictly followed and problems are solved in a timely manner, the plastic pelletizing extruder can efficiently and stably produce high-quality plastic particles.
