[0002] Closed rubber mixer is also called internal mixer, which is mainly used for rubber plasticizing and mixing. Internal mixer is a machine with a pair of rotors of specific shape and relative rotation, which intermittently plasticizes and mixes polymer materials under a closed state with adjustable temperature and pressure. Rubber plasticizing and mixing are two important rubber processing processes. At present, the most widely used and effective plasticizing method for raw rubber plasticizing is mechanical plasticizing. Its principle is to use the high shear force of the machine to destroy and degrade the rubber macromolecular chain to obtain plasticity. Mixing is another rubber mixing process based on plasticizing, which can be achieved through a mixer. By adding the corresponding compounding agent in the mixer and fully mixing and reacting with the plastic, the physical and chemical properties of the plastic are changed to meet the standards required by the industry.

[0026] When in use, the degraded rubber is poured into the feed frame 213, and the rubber squeezes the trapezoidal block 215, so that the trapezoidal block 215 moves downward to squeeze the first spring 217, and the rubber in the feed frame 213 enters the mixing box 1 through the feed pipe 212, and the compounding agent is added to the mixing box 1, and the double-headed motor 201 is turned on.

When heated and stirred, a large amount of irritating gas is generated by the rubber, which is Since the feed pipe 212 is in a one-way channel, the external air can enter the mixing box 1 in one direction (the same principle as the rubber entering), and the gas in the mixing box 1 is discharged into the filter box 302 through the exhaust pipe 303. The gas is filtered by the filter cartridge 305 and enters the ventilation pipe 309, and then enters the purification box 310. The activated carbon adsorption plate 311 adsorbs the gas in the purification box 310, and then it is discharged through the outlet pipe 312. When the gas enters the outlet pipe 312, the gas squeezes the sealing ball 314, so that the sealing ball 314 drives the second spring 316 to move to the left, so that the sealing ball 314 slides out from the conical bucket 313 to realize one-way exhaust of the air outlet pipe 312. When external air enters the air outlet pipe 312, it will squeeze the sealing ball 314. The sealing ball 314 cooperates with the conical bucket 313 to prevent external gas from entering. Turn on the motor 304, and the output rod of the motor 304 drives the filter cartridge 305 and the blade 306 to rotate.
