Description
Technical Field
The invention relates to the technical field of internal mixers, in particular to a variable-gap rotor for an internal mixer.
Background
The closed rubber mixing machine is called as internal mixer, also called as kneading machine, and is mainly used for plastication and mixing of rubber. The internal mixer is a machine which is equipped with a pair of rotors with specific shapes and can be relatively rotated, and can be used for plasticating and mixing polymer material in a clearance mode under the closed state of adjustable temperature and pressure, and is mainly formed from internal mixing chamber, rotor sealing device, feeding and pressing device, discharging device, driving device and machine base. In 1916, the first internal mixer in the world was produced. The mixing chamber of the internal mixer is internally provided with a pair of elliptical rotors which rotate oppositely and have a certain speed ratio. In the thirty years, cylindrical rotors were available, which had a long large rib and two small ribs. In recent years, rubber mixing is mainly completed by the mutual meshing of the ridges of the two rotors, and the rotors have the advantages of low temperature and excellent mixing quality, so that the rotors are widely regarded. During this time also a triangular rotor and an S-shaped rotor appear. In the beginning of the sixties, the rotor ridges of the foreign internal mixer are developed from two spiral ridges to four spiral ridges, and a GK type square-edged rotor, a Benbury square-edged rotor and the like appear in succession.
At present, internal mixer rotors used in industrial production are divided into two major categories: one type is a shear type rotor represented by a Burley two-edge rotor, a quadrangular rotor and a GK type quadrangular rotor, and is mainly used for mass production in the rubber industry, particularly in the tire industry; the other type is a meshing type rotor represented by a cylindrical rotor, which is mainly used for mixing rubber compounds requiring low temperature and high quality. The section of the GK type quadrangular rotor is basically similar to that of an elliptical rotor, and the mixing mechanism is basically consistent with that of the mixing of the Bobury; the rotor has one pair of main and auxiliary edges in the working part. The main edge is composed of a long edge and a short edge. The long edge is left-handed 30 degrees, the short edge is right-handed 48 degrees, the length ratio of the long edge to the short edge is about 6:4, and a low flat small edge is respectively arranged between the long edge and the short edge. The two small edges are opposite in rotation direction and rotate by 30 degrees to form secondary edges of the rotor. The ratio of the major to minor edges is typically 10: 9. Because the minor rib diameter is smaller than the major rib diameter, there is substantially no circumferential shearing action of the compound on the minor ribs. The different radial clearances of the main arris and the auxiliary arris and the chamber wall enable the rubber to form two flow layers which are continuously accumulated, separated and supplemented, thereby greatly contributing to the strengthening of the mixing effect. In addition, the two auxiliary edges enhance the shunting function and the axial stirring function on the sizing material.
The mixing action of the meshed cylindrical rotor internal mixer with the cylindrical rotor is completely different from that of a shearing type rotor internal mixer; the rubber mixing function of the rubber mixing machine is mainly completed by two meshed cylindrical rotors, the meshed rotors are cylindrical, the cylindrical rotors are respectively provided with a large long-strip-shaped spiral ridge and two small ridges, the shapes of the small ridges of a pair of rotors are not consistent, the two rotors rotate oppositely and have the same rotating speed, and the convex surface of one rotor is meshed into the concave surface of the other rotor; because the diameters of the root part and the top part of the rotor ridge are greatly different, different peripheral speeds are formed, a larger speed gradient is generated, and a strong friction shearing action is generated on the rubber passing through the rotors. The pushing action generated by the long-strip-shaped spiral convex edges pushes the rubber material to the other end from one end of the banburying chamber; as the rotors rotate, the glue is pushed back by the spiral ridges of the other rotor. The rubber material moves around the mixing chamber continuously and the rubber material level is updated continuously by the circulation. Meanwhile, because the clearance between the two rotors is small, the deformation of the area between the two rotors is severe when the rotors rotate, and the rubber material is strongly rolled. The surface area of the working part of the cylindrical rotor is 50 percent larger than that of other types of rotors with corresponding feeding amounts, so that good heat exchange can be realized, and long-term mixing can be carried out at low mixing temperature. In addition, the feeding characteristic of the cylindrical rotor is poor, and the function of the upper top bolt is mainly to improve the feeding capacity of the rotor. The discharge of the mesh type internal mixer is flaky and accompanied by small scraps, and the discharge time is long.
From 1956, China manufactured internal mixers mainly by using elliptical rotors of the Burley type. Quadrangular rotors were developed in the seventies, and then, some GK-type rotors and cylindrical rotors were introduced from abroad. At present, the rotor of the burley type is most widely applied in rubber industrial production in China. But this has not met the practical demands of production. The research of new rotors will be an important topic of the following research.
