The conical twin-screw extruder is a kind of efficient mixing and extrusion equipment. The machine has the characteristics of small shear rate, difficult decomposition of materials, uniform plasticization and mixing, stable quality, high output, wide application range and long service life. With the company's various specifications of mold and auxiliary machine production line, you can directly make PVC powder
Forming plastic products with different sections such as pipes, plates, profiles, etc.
This series of electrical control system of conical twin screw plastic extruder has two kinds of common control and microcomputer control. There are two main drive modes, DC speed regulation and frequency conversion speed regulation, for the user to choose.
Main features:
Soft plasticizing concept runs through the screw design all the time, providing a powerful guarantee for the high-speed extrusion of UPVC pipes
Reliable two-stage screw core external circulation temperature control system ensures that different formulations can produce high-quality UPVC pipes
High efficiency and low noise air cooling system reliable and effective vacuum exhaust system, high precision, wide speed regulation, forced quantitative feeding system, high performance reduction torque distribution gearbox, perfect accurate temperature automatic control system, accurate and stable [1] speed regulation system
Function and purpose:
The conical twin-screw extruder has the characteristics of uniform plasticizing and mixing, high output, stable quality, wide application range, long service life, direct molding of PVC powder, etc. Equipped with corresponding molding head mold and auxiliary
The machine can directly extrude all kinds of thermoplastic plastics, especially PVC powder, into plastic products such as pipes, plates, sheets, bars, films and profiles, and also can complete the modification of various plastics and powder manufacturing
Granulation process.
The conical twin-screw extruder has stable performance, which can make the melt well plasticized and extruded at a lower temperature. The cylinder is equipped with a cast aluminum heater, which has high thermal efficiency, fast and even 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 a DC motor, with stable operation, large transmission torque and high efficiency. Stepless leveling can be achieved by imported frequency converter or DC governor
Stable speed regulation, high precision and energy saving. The intelligent double display digital temperature controller is adopted, with high control accuracy and small temperature fluctuation. Equipped with overload protection and fault alarm, constant temperature of screw core oil circulation, oil cooling of cylinder
It is equipped with vacuum exhaust pipe device and quantitative feeding device.
