Description

Technical Field

[0002] Internal mixer is a device that mixes raw materials under high temperature and high pressure. It is mainly used for processing rubber, plastic, composite materials and other materials. During operation, the internal mixer usually drives the material to rotate at high speed in a closed high-pressure chamber through two relatively rotating rotors inside, so as to fully mix, plasticize and heat the material.

[0003] In the prior art, the internal mixer relies on two relatively moving rotors to drive the rubber raw materials to move and contact during production, and spiral blades for driving the rubber raw materials are installed on the outer circumference of the rotors. The spiral blades are driven to move by the high-speed rotation of the two rotors to drive the raw materials to move and mix. In this process, gaps will appear between the spiral blades of the two rotors during movement, and the raw materials inside the gaps cannot fully contact the spiral blades, which results in poor cutting effect of this part of the raw materials, resulting in a large volume of this part of the raw materials affecting the fusion efficiency, and as the rotors run at high speed, this results in a fast movement speed of the material between the two rotor gaps, and this part of the raw materials cannot fully contact the outer wall of the rotor and the inner wall of the internal mixer for heat conduction, resulting in poor heating efficiency.

[0004] In view of the above situation, in order to overcome the above technical problems, the present invention designs a rubber high-speed intelligent internal mixer. Summary of the invention

A medium for heat conduction is arranged inside the heating box 11, and the medium is oil. A heater for heating the medium is arranged inside the heating box 11. The heater heats the oil inside the heating box 11. A circulating pump 12 is installed outside the heating box 11. The input end of the circulating pump 12 is connected to the inside of the heating box 11. The output end of the circulating pump 12 is fixedly installed and connected to an output pipe 13. The circulating pump 12 transports the heated oil to the inside of the output pipe 13. An inner heat conduction cavity 63 is opened inside the rotor 61 at one end thereof. A guide channel 64 is fixedly installed at the center of the inner heat conduction cavity 63 and extends toward the opening of the inner heat conduction cavity 63. A plurality of connection ports 65 are opened through one end of the guide channel 64 toward the inside of the inner heat conduction cavity 63. An end of the rotor 61 located at the opening of the inner heat conduction cavity 63 is rotatably connected to an external rotating joint 14, which can guide the oil inside the guide channel 64 to the inside of the loop pipe 142 during the rotation of the rotor 61. An inner rotating joint 141 is fixedly installed inside 14, and the output pipe 13 transports the oil to the inside of the guide channel 64 through the inner rotating joint 141, and flows to the inner heat conduction cavity 63 outside the guide channel 64 through several connecting ports 65 of the guide channel 64. As the oil passes through the inner heat conduction cavity 63, the rotor 61 itself can be heated, and then the material on the outer wall of the rotor 61 is heated to ensure the heating efficiency and uniformity of the material when the rotor 61 rotates at a high speed. One end of the inner rotating joint 141 is rotatably connected to the opening part of the guide channel 64, so that the oil can be transported to the inside of the guide channel 64 during the rotation of the rotor 61. The other end of the inner rotating joint 141 is fixedly connected to the output pipe 13. A loop pipe 142 is fixedly installed on the outer wall of the outer rotating joint 14. The loop pipe 142 is connected to the inside of the heating box 11. The loop pipe 142 can circulate the oil to the inside of the heating box 11. Two cavities are formed inside and outside the inner rotating joint 141, and the loop pipe 142 is connected to the cavity outside the inner rotating joint 141.

[0043] As an embodiment of the present invention, refer to Figure 8 and Fig.11 An internal reflux groove 74 is provided inside the scraper 7, and a first joint 75 and a second joint 76 connected to both ends of the internal reflux groove 74 are fixedly installed outside the scraper 7. The first joint 75 is connected to the output pipe 13 through a second connecting pipe 78, and the second joint 76 is connected to the inside of the heating box 11 through a first connecting pipe 77. The second connecting pipe 78 is connected to the output pipe 13, which can guide the hot oil inside the output pipe 13 to the first joint 75 and the internal reflux groove 74 to heat the scraper 7. The second joint 76 guides the hot oil to the first connecting pipe 77 and the inside of the heating box 11 to complete the oil flow circulation.

[0044] As an embodiment of the present invention, refer to Fig.11The internal reflux groove 74 is opened along the corner inside the scraper 7, and the internal reflux groove 74 is opened along the corner of the scraper 7, so that the internal reflux groove 74 is closer to the first arc scraper blade 71, the second arc scraper blade 72 and the bottom scraper blade 73, and the heat can be preferentially conducted to the first arc scraper blade 71, the second arc scraper blade 72 and the bottom scraper blade 73, so that the temperature of this part is the highest, which is more conducive to softening and cutting the rubber raw material.

[0045] Working principle:

[0046] During use, by adjusting the output end of the electric push rod 84 to contract, the movable seat 82 can be driven to rotate clockwise with the internal rotating shaft of the fixed seat 81 as the center; then the inner scraper 7 No. 1 can be pushed toward the rotor 61, so that the bottom scraper blade 73 of the scraper 7 and the first arc scraper blade 71 are respectively attached to the outer wall of the rotor 61 and the first side outer wall of the spiral leaf 62, thereby entering the first state of the cleaning mode; in the first state, the height and position of the scraper 7 No. 1 can be adjusted by the lifting electric push rod 94 and the electric slide rail 93, and the second arc scraper blade 72 of the scraper 7 No. 1 can be attached to the second side outer wall of the spiral leaf 62. With the axial movement of the rotor 61, the outer walls on both sides of the spiral leaf 62 can be cleaned to avoid the adhesion and solidification of materials;

[0047] When the electric slide rail 93 drives the scraper 7 to move axially along the outer wall of the rotor 61 to the two ends of the rotor 61, the material at the connection between the rotor and the bearing is scraped to prevent the material in this area from solidifying; when the material is in the cutting state, the scraper 7 can move between the two rotors 61 to cut the rubber material between the two rotors 61 that is difficult to contact with the spiral blades 62.

[0048] A heater for heating the medium is arranged inside the heating box 11. The heater heats the oil inside the heating box 11. The circulating pump 12 transports the heated oil to the inside of the output pipe 13. The output pipe 13 transports the oil to the inside of the guide channel 64 through the inner rotating joint 141. The oil flows to the inner heat conduction cavity 63 outside the guide channel 64 through several connecting ports 65 of the guide channel 64. As the oil passes through the inner heat conduction cavity 63, the rotor 61 itself can be heated, and then the material on the outer wall of the rotor 61 can be heated to increase the heating speed of the material. After the heating is completed, the outer rotating joint can realize the rotation of the rotor 61 to guide the oil inside the guide channel 64 to the loop pipe 142 and the inside of the heating box 11, thereby completing the oil circulation.

[0049] The second connecting pipe 78 is connected to the output pipe 13, and can guide the hot oil inside the output pipe 13 to the first joint 75 and the internal reflux groove 74. The scraper 7 itself is heated by the oil, and the rubber raw material can be heated during the cutting process, thereby improving the uniformity of the equipment's heating of the raw material and the heating efficiency of the equipment. At the same time, when scraping the material, the heated scraper 7 contacts the solidified material to soften it, reducing the difficulty of scraping and improving the scraping effect.
