Description

Novel screw rod

Technical Field

The utility model belongs to the technical field of screws, and particularly relates to a novel screw.

Background

A screw, the outer surface of which is cut with a cylinder of a spiral groove or a cone of a conical surface spiral groove; the extrusion process shows that the screw works at high temperature, certain corrosion, strong abrasion and high torque, so the screw must resist high temperature and not deform at high temperature; wear resistance and long service life; corrosion resistance and corrosiveness of materials; high strength, high torque and high rotation speed; the cutting performance is good; residual stress after heat treatment is small, thermal deformation is small, and the like; however, the existing screw cannot enhance shearing and reduce discharge amount;

for example, chinese patent CN201810745615.5 discloses a twin-screw extruder and application thereof, in which "the twin-screw extruder comprises a cylinder, a feeding device and a vacuum pipe anti-blocking device, the feeding device comprises a pellet cylinder, a powder cylinder and a material amount control system; the bottoms of the granular material cylinder and the powder cylinder are provided with discharge ports which are communicated with feed inlets arranged on the double-screw extruder through feed pipes; the bottom of the granule jar is provided with a rotary table which rotates around the center of the jar bottom and has the same size as the jar bottom, and the rotary table is provided with through holes with different sizes. The method achieves the purpose of use, and simultaneously, part of powder or glass fiber or materials are brought into a vacuum pipeline when the vacuum is sucked due to the strong suction capability of the vacuum. Part of the liquid is retained in the vacuum pipeline to cause pipeline blockage, and part of the liquid enters the vacuum pump, so that the service life of the vacuum pump is shortened. The screw has the technical effects of serious influence on production stability, difficulty in cleaning due to longer pipelines, and the like, but the existing screw is used for realizing reinforced shearing, the discharging amount is reduced by setting the structure of the extruder, and the screw structure is not changed.

In order to solve the problems, a novel screw is provided in the present application.
