The existing extruder for PE pipe production (Announcement No.: CN209158871U) has the following disadvantages in use:

During use, the first gear, the second gear and the third gear are driven by a driving motor to rotate successively, so that the two crushing rollers and the screw rotate, which is beneficial to the stirring, mixing and crushing of the raw materials, thereby improving the uniformity of subsequent hot melt extrusion. However, in the process of crushing the raw materials, some of the raw materials may not be crushed very evenly, resulting in large differences in the size and shape of different particles, which will cause uneven melting during the plasticization process and may affect the appearance quality and performance of the product. For this reason, this patent proposes an extruder for PE pipe production to solve the above problems.
