The specific working principle is that the material enters the extruder from the hopper, and is transported forward by the rotation of the screw. During the forward movement, the material receives the heating of the barrel, the shearing and compression brought by the screw. The material is melted, thus realizing the change between the three states of glass state, high elastic state and viscous flow state. In the case of pressurization, the material in a viscous flow state passes through a die with a certain shape, and then becomes a continuum with a cross-section similar to the die according to the die.

The extruder needs to cut the material after the material is extruded. In the prior art, the cutting mechanism involved generally uses an independent cutter to cut the material. This cutting method has low cutting efficiency, and is used for cutting materials with high viscosity.
