Abstract

The invention discloses a variable-gap rotor for internal mixers, which includes front and rear rotors used in conjunction with rotary meshing, the rotor includes a rotor body arranged on a rotating shaft, and a first long rib is arranged on the rotor body and the second long edge, one end of the rotor body extends along the same axial helix with the first short edge and the second short edge, and the other end of the rotor body extends along the same axial helix with the first short edge The three short edges and the fourth short edge, the third short edge, the first long edge, the fourth short edge and the second long edge are uniformly arranged on the rotor body in sequence along the circumferential direction. In the present invention, the long edges mainly used for shearing are arranged on the rotor body, and the short edges mainly used for meshing are respectively arranged at both ends of the rotor body, so that the meshing and shearing rotors are integrated, so that the mixing The effect of refining materials reaches the extreme, which not only improves the mixing efficiency but also improves the uniformity and dispersion of mixing.

Description

technical field [0001] The invention relates to the technical field of internal mixers, in particular to a variable-gap rotor for internal mixers. Background technique [0002] The closed type rubber mixer is referred to as internal mixer, also known as kneader, which is mainly used for plasticizing and mixing of rubber. Internal mixer is a kind of machine with a pair of rotors with specific shape and relative rotation, which intermittently plasticizes and kneads polymer materials in a closed state with adjustable temperature and pressure. It is mainly composed of a mixing chamber, a rotor , Rotor sealing device, feeding and pressing device, unloading device, transmission device and machine base and other parts. In 1916, the world's first internal mixer was born. The mixing chamber of this internal mixer is equipped with a pair of elliptical rotors that rotate in opposite directions and have a certain speed ratio. In the 1930s, a cylindrical rotor appeared, which had a lo...
