Description

Special screw rod for high glass fiber

Technical Field

The utility model relates to a fine special screw rod of high glass belongs to screw rod technical field.

Background

The screw has the characteristics of good cutting processability, small residual stress after heat treatment, small thermal deformation and the like. The screws in the prior art only have screw ridges from top to bottom and do not have other structures for promoting the air in the materials to be discharged, so that the quality of extruded products is low. In order to solve the above difficulties, a special high-glass-fiber screw with a complex screw ridge structure needs to be developed.

Disclosure of Invention

The utility model aims at providing a fine special screw rod of high glass.

The utility model discloses the problem that solves is that prior art's screw rod all only has top-down's spiral shell arris, does not have the problem of other promotion material in air escape's structure.

For realizing the purpose of the utility model, the utility model adopts the technical proposal that:

high fine special screw rod of glass, including square obstacle piece, screw head, ear arris, horizontal obstacle piece, vertical obstacle piece, full spiral arris, the screw body, toper arris, half spiral arris and square obstacle piece, be equipped with the screw head on the screw body, be equipped with the ear arris outside the screw body upper end, the ear arris has horizontal obstacle piece, and horizontal obstacle piece is located screw body upper end periphery, and vertical obstacle piece is located horizontal obstacle piece below, and the screw is equipped with four vertical obstacle pieces outward, and the screw is equipped with top-down's full spiral arris outward, and the screw is equipped with a plurality of toper arris outward, and the external left side of screw is equipped with square obstacle piece, and square obstacle piece is located toper arris below, and the external right side of screw is equipped with a plurality of half spiral arris, is disconnected between the half spiral arris, and half spiral.

The tip of the conical edge faces the side face.

The utility model has the advantages that: the lug ribs and the transverse barrier blocks are combined, so that materials close to a discharge port of the machine barrel can be stirred and extruded through the screw ribs with different shapes, air in the materials can be extruded out, and the longitudinal barrier blocks can be ground on the materials, so that the air in the materials can be extruded out; the material can be torn off by the conical ribs, so that the material is fully stirred in the subsequent spiral ribs, and the material can be fully mixed by combining the square barrier blocks and the semi-spiral ribs.
