Non-woven equipment - screw extruder
Release time:
2022-06-25
Non-woven equipment - screw extruder Screw extruder is a widely used basic equipment in polymer processing, and is also an important equipment in spunbond and meltblown nonwovens production lines. The basic working principle of the Nonwoven Machine screw extruder: After the solid raw material enters the feed section of the extruder from the feeding port, it is pushed forward as the screw rotates. In this process, the heat energy provided by the heating device, the shear heat generated by the screw itself during the rotation process, and the change in the volume of the screw slot, the raw material is constantly squeezed, and the strong friction between each other is caused by the continuous heating, so that the raw material changes from the initial solid state to a highly elastic state, and finally melts into a viscous flow polymer melt. Under the thrust of the screw, it is extruded from the machine head at a certain pressure. Screw extruder, mainly composed of screw and sleeve, drive device, heating and cooling device, electrical control system and other parts.
