Background

The drip irrigation pipe is an important irrigator in a drip irrigation system, and water and nutrients required by crops are uniformly and slowly dripped into soil of a root area of the crops through a low-pressure pipeline system and an irrigator arranged on a capillary according to the water requirement of the crops.

Extruders belong to one of the classes of plastic machines. 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 machine head neck mold used by the existing special extruder for the drip irrigation pipe does not have a heat dissipation mechanism, and after the extruder head neck mold is used for a long time, the temperature of the extruded raw material is high, the plasticity speed is low, and the quality of the produced drip irrigation pipe is easily influenced.
