Furthermore, the layering section comprises a cylindrical inner cylinder axially arranged on the conversion layer, an inner-layer material passes through the cylindrical inner cylinder, and a space for passing an outer-layer material is formed between the cylindrical inner cylinder and the inner side of the sleeve.
Furthermore, the conversion mechanism comprises a plurality of outer conversion pipes and inner conversion pipes which are circumferentially arranged on the conversion layer, one end of each outer conversion pipe is communicated with the bottom of the cylindrical inner cylinder, the other end of each outer conversion pipe is communicated with the extrusion die, one end of each inner conversion pipe is communicated with the space passing through the outer layer material, and the other end of each inner conversion pipe is communicated with the extrusion die.
Further, the outer transition pipe and the inner transition pipe are arranged at intervals.
Further, the included angle between the outer transition pipe and the sleeve axis is 30-60 degrees.
Further, the included angle between the inner transition pipe and the sleeve axis is 20-50 degrees.
The utility model has the following beneficial effects:
(1) the materials are layered through the layering section, then the materials in the inner layer are converted into the outer layer, the materials in the outer layer are converted into the inner layer, and the materials decomposed by the screw rod are also transferred from the outer layer to the inner layer, so that the surface of the section bar is free from black lines, and the appearance quality of the section bar is improved;
(2) the cylindrical inner cylinder is used for layering materials, the materials in the cylindrical inner cylinder are inner layer materials, and the materials outside the cylindrical inner cylinder are outer layer materials;

Detailed Description
Example 1
Referring to fig. 1 to 3, the embodiment provides a black line removing device for an extruder, which includes a sleeve 1, wherein the sleeve 1 is arranged inside one end of a confluence core 6 connected with an extrusion die, a solid conversion layer 3 is arranged in the sleeve 1, a layered section for dividing a material into an inner layer and an outer layer is arranged on one side of the conversion layer 3 away from the extrusion die, and a conversion mechanism for converting the inner layer material and the outer layer material is arranged on the conversion layer 3.
Example 2
Referring to fig. 1 to 3, this embodiment is further improved on the basis of embodiment 1, specifically, the layered section includes a cylindrical inner cylinder 2 axially disposed on the conversion layer 3, an inner material passes through the cylindrical inner cylinder 2, and a space for passing an outer material is formed between the cylindrical inner cylinder 2 and the inner side of the sleeve 1.
