Description

Technical Field

[0001] This utility model relates to the field of rubber processing technology, and more specifically, to a high-precision internal mixer. Background Technology

[0002] Internal mixers are key equipment in the rubber industry, mainly used for the plasticizing and mixing of rubber. In the production of rubber products such as tires, rubber hoses, and rubber sheets, internal mixers improve the physical and chemical properties of rubber by mixing it with various chemical raw materials. They use a pair of rotors of specific shapes that rotate relative to each other to intermittently plasticize and mix polymer materials in a closed environment with adjustable temperature and pressure.

[0003] Based on the above, the inventors have discovered that existing internal mixers improve the mixing effect by lowering a pressure bar from above the mixing chamber to apply pressure to the material. However, during the pressure bar sealing process, powdery raw materials are easily scattered by the downward pressure of the pressure bar, causing pollution to the surrounding environment. At the same time, after the mixing is completed, the pressure bar is reset to facilitate material cooling and heat dissipation. At this time, the odor from the processed material flows directly into the air. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a high-precision feeding internal mixer, aiming to achieve a more practical purpose.

In addition, it is equipped with easily replaceable filter components to filter the gas generated during internal mixing, further protecting the processing environment.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A high-precision feeding internal mixer includes a support platform, a mixing chamber is fixedly connected to one end of the support platform near the front, and a support frame is fixedly connected to one end of the support platform near the rear. A hydraulic cylinder and an adjusting motor are fixedly connected to the top surface of the support frame.

[0009] The output end of the regulating motor is fixedly connected to a lead screw, and a ball slider is sleeved on the outside of the lead screw. A protective cover is fixedly connected to one side of the ball slider. A guide rod is provided through the side of the protective cover away from the ball slider, and a filter mechanism is provided on the lower front side of the protective cover.

[0010] Furthermore, the filtration mechanism includes an air guide pipe, a fan is fixedly connected to the top of the air guide pipe, and an installation plate is fixedly connected to the middle of the air guide pipe, with a filter element snapped into the middle of the installation plate.

[0015] 3. Beneficial Effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) This solution uses the rotation of the lead screw in conjunction with the ball slider to make the protective cover descend vertically, so that the bottom of the protective cover fits against the top surface of the mixing chamber. The guide rod plays a limiting and guiding role, ensuring the stability of the movement of the protective cover. Compared with the existing technology, the protective components can avoid the problem of material flying during the processing, and at the same time reduce the problem of gas diffusion after processing, thus purifying the processing environment.

[0018] (2) By setting up a filtration mechanism, the fan generates suction, and the odor inside the mixing chamber flows into the air duct through the air inlet. The odor is filtered by the filter element inside the mounting plate and then discharged from the fan. At the same time, the mounting plate is installed with bolts, which facilitates the replacement of the filter element. Compared with the existing technology, the setting of a filter component that is easy to replace can filter the gas generated during mixing and further protect the processing environment.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Please see Figure 1-5 A high-precision feeding internal mixer includes a support platform 1, a mixing chamber 2 is fixedly connected to one end of the support platform 1 at the front side, and a support frame 3 is fixedly connected to one end of the support platform 1 at the rear side. A hydraulic cylinder 4 and an adjusting motor 5 are fixedly connected to the top surface of the support frame 3.

[0028] The output end of the regulating motor 5 is fixedly connected to a lead screw 8. A ball slider 9 is sleeved on the outside of the lead screw 8. A protective cover 10 is fixedly connected to one side of the ball slider 9. A guide rod 11 is provided through the side of the protective cover 10 away from the ball slider 9. A filter mechanism 12 is provided on the lower front side of the protective cover 10. The regulating motor 5 is started to drive the lead screw 8.

[0029] See Figure 4 The filtration mechanism 12 includes an air guide pipe 13, a fan 14 is fixedly connected to the top of the air guide pipe 13, and an installation plate 15 is fixedly connected to the middle of the air guide pipe 13. A filter element 16 is snapped into the middle of the installation plate 15. The filtration mechanism 12 is provided in order to filter the odor generated after material processing.

[0030] See Figure 1 The output end of the hydraulic cylinder 4 is fixedly connected to the pressure block 6, which is located directly above the mixing chamber 2. Inside the mixing chamber 2, there is a pair of rotors 7 in opposite directions. When the material is put into the mixing chamber 2, the two rotors 7 work together to mix the material. The hydraulic cylinder 4 is started to drive the pressure block 6 to descend, apply pressure to the material, and improve the processing effect.

[0031] See Figure 2The protective cover 10 is located outside the support frame 3 and is slidably connected to the support frame 3. The top end of the guide rod 11 is fixedly connected to the support frame 3. The rotation of the lead screw 8, in conjunction with the ball slider 9, causes the protective cover 10 to descend vertically, so that the bottom end of the protective cover 10 is in contact with the top surface of the mixing chamber 2. The guide rod 11 plays a limiting and guiding role, ensuring the stability of the movement of the protective cover 10.

[0032] See Figure 4 The air duct 13 is fixedly connected to the protective cover 10. A set of bolts is threadedly connected to the connection between the mounting plate 15 and the air duct 13. When the fan 14 is started, it generates suction, which causes air to be discharged through the air duct 13. The air is filtered by the filter element 16 inside the mounting plate 15. At the same time, the mounting plate 15 is installed by bolts, which facilitates the replacement of the filter element 16.

[0033] See Figure 5 A set of air intake holes 17 are provided on the inner side of the lower end of the protective cover 10. The air intake holes 17 are connected to the air guide pipe 13. After the processing is completed, the hydraulic cylinder 4 drives the pressure block 6 to reset. At this time, the odor inside the mixing chamber 2 flows into the air intake holes 17.

[0034] In use: Place the material into the mixing chamber 2, start the regulating motor 5 to drive the lead screw 8. The rotation of the lead screw 8, in conjunction with the ball bearing slider 9, causes the protective cover 10 to descend vertically, so that the bottom end of the protective cover 10 is in contact with the top surface of the mixing chamber 2. The guide rod 11 acts as a limit guide to ensure the stability of the movement of the protective cover 10. Start the hydraulic cylinder 4 to drive the pressure block 6 to descend, applying pressure to the material. At the same time, the two rotors 7 cooperate with each other to mix the material. After processing, the hydraulic cylinder 4 drives the pressure block 6 to reset, and the blower 14 is started to generate suction. At this time, the odor inside the mixing chamber 2 flows into the air guide pipe 13 through the air intake hole 17, is filtered by the filter element 16 inside the mounting plate 15, and is then discharged from the blower 14. At the same time, the mounting plate 15 is installed with bolts, which facilitates the replacement of the filter element 16, ensures the filtration effect, and reduces air pollution.
