Characteristics of conical twin screw extruder
With the rapid development of the economy today, the application of various mechanical tools has brought significant help to people's production and life. Not only has it solved the problem of high production, time and energy consumption, but it has also made great contributions to sustainable development.
Function and purpose:
The conical twin screw extruder has the characteristics of uniform plasticization and mixing, high yield, stable quality, wide adaptability, long service life, and direct molding of PVC powder. Equipped with corresponding molding head molds and auxiliary machines, various thermoplastic materials, especially hard polyvinyl chloride powder, can be directly extruded into plastic products such as pipes, plates, sheets, rods, films, and profiles. It can also complete the modification and powder granulation process of various plastics.
The conical twin screw extruder of Zhoushan Yingke Plastic Machinery Co., Ltd. has stable performance and can effectively plasticize and extrude the melt at lower temperatures. The barrel of the extruder 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 transmission part specially designed by Zhoushan Yingke Plastic Machinery Co., Ltd. adopts a new type of variable frequency motor drive or DC motor drive, which operates smoothly, has large transmission torque, and high efficiency. By using imported frequency converters or DC speed regulators, stepless and stable speed regulation can be achieved, with high accuracy and energy saving. Adopting an intelligent dual display digital temperature controller, it has high control accuracy and small temperature fluctuations. Equipped with overload protection and fault alarm, screw core oil circulation constant temperature, barrel oil cooling and other functions, and equipped with vacuum exhaust pipe device and quantitative feeding device.
It is an efficient equipment for mixing and extruding conical twin screw extruders. This machine has the characteristics of low shear rate, difficulty in material decomposition, uniform plasticization and mixing, stable quality, high output, wide application range, and long service life. Equipped with various specifications of molds and auxiliary machine production lines produced by our company, PVC powder can be directly made into plastic products with different cross-sections such as pipes, plates, and profiles.
The electrical control system of the conical twin screw plastic extruder is equipped with two types: ordinary control and microcomputer control. There are two main driving modes for users to choose from: DC speed regulation and variable frequency speed regulation.
Main features:
The gentle plasticization concept has always been integrated into the screw design, providing a strong guarantee for the high-speed extrusion of UPVC pipes
A reliable two-stage screw core external circulation temperature control system ensures that different formulations can produce high-quality UPVC pipes
Efficient and low noise air cooling system, reliable and effective vacuum exhaust system, high-precision, wide speed regulation, forced quantitative feeding system, high-performance deceleration torque distribution gearbox, perfect and accurate temperature automatic control system, and precise and stable speed regulation system.
