Problems solved by technology
Due to the unreasonable structural design, the screw in the prior art is likely to cause problems such as unstable product quality and poor product appearance quality due to uneven mixing.
In addition, due to the different extrusion pressure, the product size is unstable and the consistency is poor, and the conveying capacity of the existing screw is also low, resulting in low production efficiency

The invention relates to a screw and an extruder. The screw has a connecting part connected with the main body of the extruder, and a feeding part, a homogenizing part and a conveying part arranged downstream of the connecting part along the length direction of the screw. The feeding part It has at least a first helical leaf and a first helical body, and a plurality of first notches arranged at intervals along the extending direction of the first helical body are constructed on the first helical body; Three helixes, the third helical leaf is branched from the second helical leaf, and extends to the side of the conveying part, and is connected to the second helical leaf at the front end; the conveying part has at least the fourth helical leaf and the second helical body, A plurality of second notches are arranged at intervals along the extending direction of the second spiral body. The screw of the present invention can divide the rubber material and change the mixing mode of the rubber material, thereby improving product quality, changing the flow direction of the rubber material, and generating fast material flow, thereby improving the conveying capacity of the screw rod to the rubber material.
Description
technical field [0001] The invention relates to the technical field of extruder components, in particular to a screw, and at the same time, the invention also relates to an extruder with the screw. Background technique [0002] The screw is regarded as the "heart" of the equipment, which has an important impact on product quality, maximum output, and production efficiency. Due to the unreasonable structural design, the screws in the prior art are likely to cause problems such as unstable product quality and poor product appearance quality due to uneven mixing. In addition, due to different extrusion pressures, the size of the product is unstable and the consistency is poor, and the conveying capacity of the existing screw is also low, resulting in low production efficiency. Contents of the invention [0003] In view of this, the present invention aims to provide a screw, which can improve the conveying capacity of rubber materials and improve product quality. [0004] In...
