Abstract
The invention relates to a double-cycloid section type banbury mixer rotor, which comprises a front rotor and a rear rotor. The front rotor and the rear rotor are respectively provided with four edge structures in columnar structure. The four edge structures include levo-long edges, levo-short edges, dextro-long edges and dextro-short edges. Interaction of the front rotor and the rear rotor makes a rotor section cavity show a periodical change from big to small and then from small to big, thus enhancing dispersion mixing of a rubber material. High strength deep mixing and distributive mixing are generated between edge peaks of the front rotor and the rear rotor and the inner wall of a mixing chamber, thus improving the rubber mixing effect. The sections of the front rotor and the rear rotor adopt a double-cycloid engagement mode, thereby reaching constant speed ratio rotation and having the characteristics of high distributive mixing and dispersion mixing. The front rotor and the rear rotor involved in the invention have the characteristics of simple structure, low manufacturing cost and convenient installation, thus shortening the production cycle of the rotor and improving production efficiency.
