Abstract
Description
Technical Field
[0001] The utility model relates to the field of extruders, in particular to a high-efficiency extruder with uniform heating. Background Art
[0002] The extruder relies on the pressure and shear force generated by the rotation of the screw to fully plasticize and evenly mix the materials, and pass through the die. Among extruders, in general, the most basic and most common is the single-screw extruder, which mainly includes six parts: transmission, feeding device, barrel, screw, die head and die. When in use, the plastic raw material is heated and melted at the extrusion group to make the plastic in a plasticized state, and then extruded through the die head under the thrust of the screw and cooled. The existing plastic raw materials are heated unevenly during the transportation process, which reduces the melting speed and affects the extrusion speed, which brings certain adverse effects to people's use process.
