In the process of processing and forming plastics, particularly for some tubular parts, an extruder is basically used, and the extruder is a machine which is used for heating and plasticizing and pushing forward by a screw to form the plastics by the action of the screw and a machine head barrel. Because the plastic extruding machine has high requirements on the properties of raw materials, the raw materials cannot contain moisture and cannot be damped to generate the phenomenon of caking, otherwise, the defects of spots, rough pipe wall and the like on the surface of a pipe product are easily caused, and the problems of low pipe strength, cracking, perforation and the like of the pipe are easily caused because bubbles are generated in the damped and caked raw materials during melting and are mixed in the pipe product.

Particularly, when producing pipe products with different colors, the traditional burdening is to mix raw materials, dyeing materials and the like manually and stir the mixture through a stirring rod, and finally pour the mixed raw materials into a hopper of an extruding machine. Because the raw materials are exposed outdoors all the time during manual batching, the wetting is easy, and the problem that the dyeing material cannot be uniformly mixed with the raw materials also exists, thereby causing the uneven distribution of the mixed raw materials after entering the plastic extruding machine, easily causing the color difference of products, non-uniform local strength of pipe products and other problems. And some electric stirring devices on the market are not ideal in caking and crushing effects in mixed raw materials, and further influence the performance of pipe products.

The invention provides a crushing and stirring device for extrusion molding mixed raw materials, which is characterized in that the mixed raw materials are rolled through a compression roller and stirred through a stirring device, so that the caking phenomenon in the mixed raw materials is eliminated to the maximum extent, the raw materials are uniformly mixed, and the problem that the traditional extrusion molding finished product is poor due to the fact that the caking in the raw materials cannot be eliminated during the mixing of the raw materials is solved.
