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 rod and an extruder. The screw rod is provided with a connecting part connected with an extruder body, and a feeding part, a homogenization part and a conveying part which are sequentially arranged at the downstream of the connecting part along the length direction of the screw rod; the feeding part is at least provided with a first spiral blade and a first spiralbody; a plurality of first nicks which are formed in a spacing manner in the extending direction are formed in the first spiral body; the homogenization part is provided with a second spiral blade anda third spiral blade, wherein the second spiral blade and the third spiral blade are arranged in a spacing manner; the third spiral blade consists of one second spiral blade branch, extends towards one side of the conveying part, and is connected with the second spiral blade at the front end; and the conveying part is at least provided with a fourth spiral blade and a second spiral body, whereina plurality of nicks which are formed in a spacing manner in the extending direction are formed in the second spiral body. The screw rod disclosed by the invention can divide glue, and can change themixing manner of the glue, so that the product quality can be improved, the flowing direction of the glue can be changed, quick material flows can be generated, and the conveying capacity of the glueby the screw rod can be improved.
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...
