The working principle of automatic flushing screen changer

In the process of plastic extrusion production, the plastic melt will produce some decomposition products after long time plasticization, and the raw material itself also contains some impurities. The existence of these impurities not only affects the quality of products, but also affects the continuity and stability of production. The mesh automatic flushing screen changer is arranged between the screw head and the extruder head to filter out impurities and foreign bodies in the plastic melt and obtain pure melt.

With the rising price of plastic raw materials, extrusion production enterprises have artificially increased the proportion of recycled materials in order to reduce production costs and increase profits. The proportion of recycled plastic materials for some agricultural plastic products is 80%~90%. The mesh changer is one of the important factors that affect the quality of plastic recycled materials. The large use of recycled recycled material greatly promotes the development of net automatic flushing screen changer, brings wide market to the application of net exchanger, and puts forward new requirements to the automatic flushing screen changer.
