Problems solved by technology

The screw is the main component that affects these factors, but the products produced by using the existing screw are particularly obvious that the dispersion is poor and cannot meet the requirements of high-end products. The most prominent is that the screw pressure and shear force are obviously insufficient.

Embodiment Construction

[0013] In order to better understand the present invention, the present invention will be further described below through specific examples. However, the invention is not limited thereby.

[0014] Such as figure 1 , figure 2 , image 3 , Figure 4 Shown is a high-pressure, high-shear screw structure diagram, which has a screw mandrel (1), a threaded element (2), an elliptical blending block (3), a heart-shaped kneading block (4), and a tooth type It consists of structural elements such as a mixing disc (5) and an anti-mixing helix (6). The material added from the feeding port is pushed by the conveying screw to the shearing and mixing element---the blending or kneading block, so that the material can be sheared, mixed and matured here, and the toothed mixing disc plays the role of blocking the material. Increase the pressure of the material in the front section to strengthen the shearing effect of the kneading block. Finally, the anti-mixing screw element plays the role...

Abstract

The invention discloses a heart valve type screw rod which consists of structural elements of a screw rod mandrel (1), a threaded element (2), an elliptic blending block (3), a heart valve type kneading block (4), a tooth-shaped mixing disc (5), a back mixing helix (6) and the like, wherein an extrusion element is sleeved on the screw rod mandrel and is coupled with the screw rod mandrel in a spline manner. The pressure and the shearing force of the screw rod can be adjusted by changing or adjusting the combination modes of the extrusion elements according to characteristics of different materials, so as to achieve an expected dispersion effect.

Description

technical field [0001] The invention relates to a heart valve-shaped screw for producing color masterbatch, which can be used for the production of color masterbatch. Background technique [0002] At present, in the plastic color masterbatch industry, the twin-screw extruder is the main equipment for extrusion and production of color masterbatch. The main factors affecting product quality are temperature, pressure, shear force, etc. The screw is the main component that affects these factors, but the products produced by using the existing screw are particularly obvious that the dispersion is poor and cannot meet the requirements of high-end products. The most prominent is that the screw pressure and shear force are obviously insufficient. Contents of the invention [0003] In order to solve the above problems, the present invention provides a valve-shaped screw. [0004] The technical scheme that the present invention adopts in order to solve its problem is: [0005] The...
