[0002] The internal mixer for rubber processing is a special equipment used for rubber mixing and processing. It is mainly used to mix and process rubber, additives and other chemical substances to achieve rubber modification and improved processing performance. The internal mixer has high processing capacity and flexibility and can adapt to various rubber materials and processing requirements. It is widely used in the rubber industry to manufacture rubber products such as tires, seals, rubber tubes, etc. Through reasonable settings and adjustments, the internal mixer can achieve the optimized formula of rubber materials, improve mixing uniformity and processing performance.

[0003] In the process of processing rubber using an internal mixer, the internal mixer heats the rubber. During the processing, the rubber softens due to heat, and the rubber molecules undergo rheological behavior under heating and shearing, making it more viscous and easily adheres to the inner wall of the internal mixer, making it difficult to clean. In most existing factories, workers are often required to use scrapers to manually clean the materials adhered to the inner wall of the internal mixer.

[0040] like Figure 1 and Figure 3As shown, a mixing component 4 is arranged on the outer surface of the hollow plate 7, and the mixing component 4 includes a mixing bin 401. One end of the hollow plate 7 penetrates into the interior of the mixing bin 401. A limiting groove 402 is arranged on the outer surface of the mixing bin 401 near the bottom.

[0042] like Figure 1 and Figure 3-4 As shown, the pressing component 5 includes a gas tank 501, the bottom of the gas tank 501 is fixedly connected to the top of the mixing bin 401, a reversible pump 502 is arranged at the top of the mixing bin 401 near one side edge, the input end of the reversible pump 502 is fixedly connected to a connecting pipe 503, one end of the connecting pipe 503 passes through the interior of the gas tank 501, and the output end of the reversible pump 502 is fixedly connected to an air supply pipe 504. After the material enters the mixing bin 607, the reversible pump 502 is first started, and the reversible pump 502 drives the connecting pipe 503 to extract inert gas argon into the interior of the gas tank 501.

[0043] like Figure 1 , Figure 3 and Figure 5-6As shown, a sealing tube 505 is fixed near the center of the top of the mixing bin 401, one end of the air supply pipe 504 penetrates into the interior of the sealing tube 505, and a piston 506 is slidably connected to the interior of the sealing tube 505.

[0044] The use method and working principle of the device are as follows: when the rubber needs to be processed by an internal mixer, the raw materials needed for rubber processing are first transported to the inside of the conveying bin 301 through the corresponding feed hoppers 305, and then the servo motor 303 is started to drive the spiral conveying tube 304 to rotate, and then the materials are transported through the spiral conveying tube 304 while mixing the materials. The mixed materials are transported to the inside of the mixing bin 401 through the hollow plate 7, and then the electric push rod 409 is started to extend and retract back and forth, driving the tooth row 410 to move back and forth along the slide 411, and then driving the gear body 407 to switch between clockwise and counterclockwise rotation, thereby driving the rotating disk 408 to rotate, wherein, as Figure 4As shown, the top of the rotating disk 408 penetrates into the mixing bin 401, and the rotating disk 408 drives the materials in the mixing bin 401 to rotate, thereby further accelerating the mixing of the materials, and finally making the raw materials for rubber processing mixed more evenly, thereby improving the uniformity of material mixing. When the material mixing is completed, the two multi-stage electric telescopic rods 404 are started to extend, driving the sliding rod 405 to move forward, thereby driving the pressure plate 406 to move to the outside of the limiting groove 402. When the outer surface of the pressure plate 406 moves to be close to the outer surface of the limiting groove 402, the mixing bin 401 and the mixing bin 607 are completely connected, wherein the width of the limiting groove 402 matches the thickness of the pressure plate 406, so when the pressure plate 406 When moving out of the limiting groove 402, the material in the mixing bin 401 will not be brought out. After the material enters the mixing bin 607, the reversible pump 502 is first started, wherein the reversible pump 502 can realize the functions of forward gas delivery and reverse gas delivery. The reversible pump 502 can deliver gas in both forward and reverse directions by changing the working mode. The design of this pump body allows the flow direction to be reversed in different situations to meet specific needs. The reversible pump 502 has flexibility and versatility in multiple application scenarios. The reversible pump 502 drives the connecting pipe 503 to extract inert gas argon from the inside of the gas tank 501. The gas enters the inside of the sealing tube 505 through the air supply pipe 504, and drives the piston 506 to move downward under the action of air pressure, thereby bringing The plurality of lifting rods 507 are driven to move downward, thereby driving the pressing block 508 to move downward to the inside of the mixing chamber 607, so as to prevent the material in the mixing chamber 607 from diffusing outward, and then the two heating wires 627 are electrically connected to the external power supply to release heat outward, wherein the two hollow blocks 606 and the mixing chamber 607 are made of stainless steel. Through the strong heat conduction effect of stainless steel, the temperature of the mixing chamber 607 is rapidly increased, thereby achieving the purpose of heating the material in the mixing chamber 607, and then the driving motor 608 is started to drive the first roller 609 to rotate, thereby driving the driving gear 610 to rotate, and the driving gear 610 drives the driven gear 611 to rotate, thereby driving the second roller 612 to rotate, so that the first roller 609 and The second rollers 612 rotate relative to each other to grind, crush and mix the materials. When the materials are mixed, the reversible pump 502 is started again to drive the air delivery pipe 504 to pump gas into the sealed tube 505. The gas flows back to the inside of the gas tank 501 through the connecting pipe 503, so that negative pressure is generated inside the sealed tube 505. Under the action of the negative pressure, the piston 506 is driven to move upward, thereby driving the pressing block 508 to move upward, and then multiple cylinders 602 are started to shorten them, driving the load-bearing frame 601 to move downward, thereby separating the mixing bin 607 from the mixing bin 401, so that the distance between the mixing bin 607 and the mixing bin 401 is greater than half the width of the mixing bin 607, and the forward and reverse motors 604 are started to drive the two support tubes 605 to rotate.Then, the mixing chamber 607 is driven to rotate. When the outlet position of the mixing chamber 607 is rotated to tilt downward, the external collecting device can be placed in a suitable position so that the material falls into the external collecting device, that is, the automatic output of the material is completed, which facilitates the output of the material in the rubber mixer. When a large amount of material is output, the two heating wires 627 are disconnected from the external power supply, and then the two hydraulic rods 618 are started to shorten them, driving the two moving plates 619 to move away from each other, and then the two semiconductor refrigeration plates 614 are electrically connected to the external power supply respectively, wherein the cold surface of the semiconductor refrigeration plate 614 faces the interior of the sealed chamber 613, wherein the semiconductor refrigeration plate 614 is a refrigeration technology based on the thermoelectric effect, which uses a semiconductor material called thermoelectric material to achieve refrigeration through the thermoelectric effect generated by electric current in the material, cools the argon gas in the sealed chamber 613, and then starts the two delivery pumps 615 to drive the two gas delivery pipes 616 to output the gas in the sealed chamber 613, and the gas enters the hollow chamber through the drainage pipe 617. The inside of the block 606 cools down the material attached to the inner wall of the mixing chamber 607 through the heat conduction of the metal, so that the material on the inner wall of the mixing chamber 607 solidifies when it is cooled. When the air pressure between the movable plate 619 and the inside of the hollow block 606 is high, the multiple springs 623 are driven by the air pressure to move to the inside of the mixing chamber 607 respectively, and then the multiple sealing blocks 624 are driven to move to the inside of the mixing chamber 607. Among them, the sealing blocks 624 and the movable plate 619 are made of high-temperature resistant polytetrafluoroethylene. Through the multiple sealing blocks The movement of 624 allows the solidified material to separate from the inner wall of the mixing chamber 607, and then the vibration pump 626 is started to vibrate the surface of the mixing chamber 607. Under the action of the vibration force, the separation of the solidified material from the inner wall of the mixing chamber 607 is accelerated, and the material attached to the mixing chamber 607 can be removed. Through the action of the cleaning component 6, the material attached to the inner wall of the mixer can be removed without the need for workers to manually scrape it, which solves the problem in the prior art that the material adhered to the inner wall of the mixer is not easy to clean and increases the labor intensity of workers.
