Working principle of single screw extruder
The single-screw extruder is mainly composed of a feeding device, a screw, a barrel, a machine head, a cooling device and a driving device. Its working principle is that the motor drives the screw to rotate in the barrel, so that the material is transported forward under the friction between the screw and the barrel. At the same time, the spiral groove on the screw causes the material to be sheared and mixed, gradually plasticized and melted. The molten material is extruded through the machine head and then cooled and solidified by the cooling device to finally obtain the desired product.
Application fields of single screw extruder
Single-screw extruders have a wide range of applications in the plastics processing industry. It can be used to produce various plastic pipes, plates, profiles and other products. In addition, it is also widely used in wire and cable, rubber products, food packaging and other fields. With the advancement of science and technology and the development of technology, the application fields of single-screw extruders will continue to expand.
The industry value of single screw extruder
As the core equipment of the plastic processing industry, the single-screw extruder has the following industry values:
1. Improve production efficiency: The single-screw extruder adopts an automated control system, which can achieve continuous and efficient production and significantly improve production efficiency.
2. Ensure product quality: By accurately controlling parameters such as temperature and pressure, the single-screw extruder can ensure product stability and consistency and improve product quality.
3. Reduce production costs: Using a single-screw extruder for production can reduce energy and raw material consumption, thereby reducing production costs.
