Description

Multifunctional extruder nozzle

Technical Field

The invention relates to the field of extruders, in particular to a multifunctional extruder nozzle.

Background

Extruders belong to one of the classes of plastic machines, originating from the 18 th century. The extruder can divide the machine head into a right-angle machine head, an oblique-angle machine head and the like according to the material flow direction of the machine head and the included angle of the central line of the screw. The screw extruder depends on the pressure and the shearing force generated by the rotation of the screw, so that materials can be fully plasticized and uniformly mixed and are molded through a neck mold. Plastics extruders can be largely classified into twin-screw extruders, single-screw extruders and, less frequently, multi-screw extruders and also screwless extruders. The existing extruder nozzle in the market at present has the inside that the air got into the shower nozzle after finishing using for need discharge the air when using next time and just can obtain intact product, caused the waste of raw materials. To this end, we propose a multi-functional extruder nozzle.
