[0002] A rubber internal mixer is an industrial device used to mix rubber and its compounding ingredients. It is widely used in the production of rubber products such as tires, seals, hoses, and tapes. Its main function is to uniformly mix various materials such as raw rubber, fillers, and plasticizers under high temperature and high pressure to fully plasticize and disperse them, forming a mixed rubber compound with good processing properties. Through the closed mixing chamber and the strong shearing action of the rotor, the rubber internal mixer can fully mix the rubber and compounding ingredients in a relatively short time, greatly improving the mixing efficiency. Modern rubber internal mixers are equipped with automatic control systems for parameters such as temperature, pressure, and time, which can accurately control various process parameters during the mixing process to ensure the stability of product quality.

[0026] A plurality of gear grooves are evenly distributed on the outer side of the blanking plate 3. The output end of the driving gear 7 is meshed with the blanking plate 3 through the arrangement of the gear grooves. The arrangement of the gear grooves enables the blanking plate 3 to move laterally inside the rectangular frame 4.

[0027] Here, the operation of the driving motor 6 enables the driving gear 7 to rotate, and the rotation of the driving gear 7 enables the blanking plate 3 to slide horizontally inside the rectangular frame 4, thereby adjusting the blanking position of the blanking plate 3;

[0028] The rotating mechanism includes a hydraulic cylinder 5. The output end of the hydraulic cylinder 5 is rotatably connected to a longitudinal movable shaft 12 via a bearing. The outer side of one end of the longitudinal movable shaft 12 is rotatably connected to an oblique rotating rod 9 via a bearing. The top of the oblique rotating rod 9 is rotatably connected to a rectangular rotating block 10 via a pin.

The dovetail slider and the dovetail slot enable the longitudinal movable shaft 12 to slide vertically on the outside of the U-shaped frame 1.

[0030] An arc-shaped support block 8 is fixed to the outside of the hydraulic cylinder 5. The arc-shaped support block 8 is close to one end of the U-shaped frame 1 and is fixedly connected to the U-shaped frame 1, so that the hydraulic cylinder 5 can be fixed so that the operation of the hydraulic cylinder 5 can drive the longitudinal movable shaft 12 to perform vertical lifting;

[0034] The operation of the hydraulic cylinder 5 enables the longitudinal movable shaft 12 to slide vertically on the outside of the U-shaped frame 1. The lifting and lowering of the longitudinal movable shaft 12 enables the rectangular rotating block 10 to drive the longitudinal rotating shaft 11 to rotate through the oblique rotating rod 9, so that the longitudinal rotating shaft 11 can drive the rectangular frame 4 to rotate, thereby adjusting the blanking angle of the blanking plate 3. By changing the angle of the blanking plate 3, the blanking rate of the blanking plate 3 can be adjusted.

[0035] By adjusting the position where the material enters the unloading plate, the material can be prevented from piling up in the same place and uneven unloading can be avoided. By adjusting the angle of the unloading plate 3, the material unloading rate can be adjusted to provide a more uniform and stable unloading process, avoiding accumulation or blockage of the material during the unloading process.
