The closed rubber mixer is referred to as the internal mixer, which is mainly used for plasticizing and mixing of rubber. Internal Mixer is a kind of machine that is equipped with a pair of rotors with a specific shape and rotates relatively, and intermittently masticates and kneads polymer materials in a closed state with adjustable temperature and pressure. , rotor sealing device, feeding and pressing device, unloading device, transmission device and machine base and other parts. Internal mixer is a kind of high-strength intermittent mixing equipment developed on the basis of open mixer. Since the appearance of the Banbury mixer in the true sense in 1916, the power of the mixer has gradually been recognized by people. It shows a series of features that are superior to the open mixer in the rubber mixing process. Such as: large mixing capacity, short time, high production efficiency; better to overcome dust flying, reduce the loss of compounding agents, improve product quality and working environment; safe and convenient operation, reduce labor intensity; be beneficial to the realization of mechanical and automated operations, etc. . Therefore, the emergence of the internal mixer is an important achievement of rubber machinery, and it is still a typical important equipment for plasticizing and mixing. The kneader is a device that produces a strong shearing action by a pair of mutually cooperating and rotating blades (usually Z-shaped), so that the semi-dry or rubber-like viscous plastic material can quickly react to the material to obtain uniform mixing and stirring. It is an ideal equipment for mixing, kneading, crushing, dispersing and repolymerizing various chemical products of various high-viscosity elastic-plastic materials. It has the advantages of uniform stirring, no dead angle and high kneading efficiency. It is widely used in high-viscosity sealants, Silicone rubber, neutral acid glass glue, chewing gum, bubble gum, pulp, cellulose, also used in batteries, inks, pigments, dyes, pharmaceuticals, resins, plastics, rubber, cosmetics and other industries. The kneader can be made into four types: ordinary type, pressure type, vacuum type and high temperature type. The temperature adjustment method adopts jacket, steam, oil heating, water cooling and other methods, and adopts hydraulic cylinder turning and cover opening. The discharge methods include hydraulic pressure, cylinder dumping, ball valve discharge, screw extrusion, etc. It can control and record the temperature, time, viscosity and other related data in production in real time through PLC. The cylinder body and the contact part between the paddle and the material are all made of stainless steel to ensure product quality. The kneader is mainly composed of six major parts: the kneading part, the base part, the hydraulic system, the transmission system, the vacuum system and the electric control system. The kneading part is composed of cylinder block, paddle shaft, wall plate, cylinder head and so on. The hydraulic system consists of a hydraulic station to operate two small oil cylinders and two large oil cylinders to complete the functions of opening and closing the large cover and turning the mixing cylinder. The electronic control system includes manual and automatic electronic control systems, which can be selected and required by the user at will, and the operation is convenient and reliable. The transmission system consists of a motor, a reducer and a gear, and the motor is matched according to the model of the kneader. In the transmission process, the motor can synchronize the speed, and after the elastic coupling reaches the reducer, the fast pulp is driven by the output device to make it reach the specified speed, and the speed can also be adjusted by the frequency converter.
