Basic classification, structure and working principle of plastic mechanical internal mixer
internal mixer can be divided into three types according to different rotor cross-sectional geometry in the internal mixer room: elliptical rotor internal mixer, triangular rotor internal mixer and cylindrical rotor internal mixer. Elliptical rotor internal mixer is most widely used in rubber industry. Basic structure of internal mixer the main components of internal mixer include internal mixer chamber, phenomenon of falling crack at the same time, upper top bolt, lower top bolt, cooling system, lubrication system, sealing device and transmission device with distinctive design characteristics of dense metamaterials. The internal mixing chamber is the main working part of the internal mixer. There are two rotors rotating relatively at different speeds for plastic mixing or mixing. Working principle of internal mixer when the internal mixer is in the rubber mixing process, after the raw rubber or other materials are added from the feeding hopper, they first fall into the upper part of the two relatively rotating rotors, and are brought into the gap between the two rotors under the pressure of the upper top bolt and the action of friction to be kneaded. Then, the rubber is divided into two parts by the protruding edge of the lower top bolt. With the rotation of the rotor, it passes through the gap between the rotor surface and the front wall of the internal mixing chamber, and reaches the upper part of the internal mixing chamber after being subjected to strong mechanical shear, tearing and kneading. Under the influence of the amplifier range transformation, data collection, data transmission, mode selection of universal testing machine and liquid crystal display of the whole machine at different speeds of the rotor, the two strands of rubber meet at the upper part of the two rotors at different speeds and enter the gap between the two rotors for repeated cycles. During the whole work of the internal mixer, the raw rubber is subjected to both strong mechanical stress and thermal oxidation cracking when being plasticized in the internal mixer, so the required plasticity can be obtained in a very short time
