Engagement rotor of internal mixer

Abstract

The present invention discloses an engagement rotor of an internal mixer, including a rotor body (4) and three ribs disposed on the rotor body (4). The three ribs are respectively of a long rib (1), a middle rib (2) and a short rib (3). The rotor is characterized in that: the long rib (1) and the middle rib (2) are same in the spiral direction, and the spiral direction of the short rib (3) is opposite to that of the long rib (1) and the middle rib (2). According to the engagement rotor of the internal mixer, the spiral direction and the angle of the short rib are changed, and the length of the short rib is increased. Compared with a conventional structure, the shortcoming that the rubber material on short rib end face can not be stirred because of a dead zone in a conventional structure is overcome, the engagement area between two rotors is increased, and the rubber mixing effect is enhanced, so that the quality of the rubber material is further improved.

Description

technical field [0001] The invention relates to an intermeshed rotor of an internal mixer. Background technique [0002] The meshing rotor of the internal mixer is more and more widely used in the rubber industry. Due to the meshing effect between the rotors and the good cooling effect, the rubber is fully mixed and stirred, and the product quality is high, such as figure 1 As shown, the helical direction of the short edge in the meshing rotor structure of the traditional structure is consistent with that of the long edge and the middle edge, and the helix angle is smaller than that of the long edge and the middle edge. There is a phenomenon of glue accumulation, this part of the rubber is always squeezed in this dead corner, and cannot return to the middle of the rotor for further turning, stirring, and mixing, which deteriorates the working condition of the end face seal and increases the impact of the rubber on the rotor. The axial force and resistance torque will affect...
