The conical twin-screw extruder, as an important plastic processing equipment, is widely used in the production process of various plastic products. Its unique conical design and twin-screw structure give it excellent performance in the field of plastic extrusion.
1. Working principle
The working principle of the conical twin-screw extruder is based on the melting and extrusion of plastic under the rotation and pushing action of the screw. When the raw materials are fed into the hopper of the conical twin-screw extruder, they are sheared, mixed and melted by the screw to form a uniform melt. As the screw rotates and pushes, the melt is transported to the die of the machine head and finally extruded.
2. Technical characteristics
1. Conical design: The conical design of the conical twin-screw extruder makes it more adaptable and flexible in the material transportation and melting process. The tapered structure can effectively adjust the residence time and melting degree of the material in the screw, thereby improving product quality and production efficiency.
2. Twin-screw structure: The twin-screw structure provides the conical twin-screw extruder with strong shearing force and mixing capabilities. The two screws mesh with each other so that the material is fully sheared, mixed and melted during the extrusion process, thus improving the uniformity and stability of the product.
3. High efficiency and low energy consumption: The conical twin-screw extruder adopts advanced transmission system and temperature control system, which can achieve efficient and stable production while reducing energy consumption and improving economic benefits.
3. Application fields
Conical twin-screw extruders are widely used in the field of plastic processing, such as the production of pipes, plates, films, wires and cables, etc. In addition, it can also be used in fields such as plastic modification, plastic recycling and regeneration to achieve resource recycling and sustainable development.
4. Examples in life
Taking the common plastic pipes in our daily life as an example, the conical twin-screw extruder plays a key role in the production process. By melting, mixing and extruding raw materials, the conical twin-screw extruder can produce plastic pipes with excellent properties, which are widely used in construction, water conservancy, agriculture and other fields. These pipes not only have excellent corrosion resistance, pressure resistance and weather resistance, but are also easy to install and have a long service life, bringing great convenience to our lives.
In short, as an advanced plastic processing equipment, the conical twin-screw extruder plays a pivotal role in the development of the plastics industry.
