Analysis on the function and application of conical twin screw extruderAnalysis on the function and application of conical twin screw extruder
The conical twin-screw extruder has the characteristics of uniform plasticizing and mixing, high output, stable quality, wide range of application, long service life, and direct molding of PVC powder. Equipped with the corresponding molding die and auxiliary machine, various thermoplastics, especially hard polyvinyl chloride powder, can be directly extruded into plastic products such as tubes, plates, sheets, rods, films, and shaped materials, which can also be completed Modification of various plastics and powder granulation process.
Conical twin-screw extruder has stable performance, which can make the melt plasticized and extruded well at low temperature. The barrel is equipped with a cast aluminum heater, which has high thermal efficiency, fast and uniform temperature rise, and is equipped with a cooling fan.
The specially designed transmission part is driven by a new type of variable frequency motor or DC motor, which runs smoothly, has a large transmission torque and high efficiency. Stepless and stable speed regulation can be achieved through imported frequency converter or DC speed regulator, with high precision and energy saving. Using intelligent dual display digital temperature controller, high control accuracy and small temperature fluctuation. Equipped with overload protection and fault alarm, screw core oil circulation constant temperature, barrel oil cooling and other functions, and is equipped with vacuum exhaust pipe device and quantitative feeding device.
