Embodiment Construction

[0012] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0013] Such as figure 1 A kind of embodiment of shown special-shaped conical screw plastic extruder of the present invention comprises barrel 1, is respectively provided with feed hopper 2 and discharge port 3 at the two ends of described barrel 1, in described The barrel 1 is provided with a screw 4, and the screw 4 is in a conical shape with a thick middle and two thin sections. The inner wall of the barrel 1 is provided with six diversion grooves, and the diversion grooves The angle of inclination with the inner side wall of the cartridge 1 is 30 degrees.

[0014] What is described in the above description is only the specific implementation of the presen...

Abstract

The invention discloses a plastic extruder with a special-shaped conical threaded rod. The plastic extruder comprises a feed cylinder, a feed hopper and a discharge port are arranged at the two ends of the feed cylinder separately, the threaded rod is arranged in the feed cylinder, and the threaded rod is in a conical shape with a thick middle and two thin ends. The conical threaded rod with the thick middle and the two thin ends is adopted, so the extrusion pressure of a plastic extruder with a single threaded rod is further increased, the shearing force of the plastic extruder with the single threaded rod is greatly improved, the material crushing and blending effect is improved, and production efficiency and product quality are improved.

Description

technical field [0001] The invention relates to a special-shaped conical screw plastic extruder. Background technique [0002] In the known technical field, the plastic extruder is a commonly used plastic processing equipment, and the screw extruder is the most commonly used mixing molding equipment. In order to complete the mixing and plasticizing process of plastics, the screw extruder is required to have Strong shearing, dispersing and mixing capabilities enable smooth extrusion of different types and components of raw materials. [0003] Existing equipment such as single-screw extruder, twin-screw extruder, reciprocating pin screw extruder, multi-screw extruder in the prior art, above-mentioned screw extruder generally has the screw rod that is cylindrical shape, shears And extrusion efficiency is difficult to improve. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a plastic extruder with high extrusion pr...
