Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber preparation technology, and in particular to a perfluoroether rubber compounding and preparation apparatus. Background Technology
[0002] Perfluoroelastomer (PFE) rubber is a special synthetic rubber with excellent high-temperature resistance, chemical corrosion resistance, and aging resistance. It is mainly composed of perfluorinated olefins and ether compounds. Due to the very stable molecular structure of PFE rubber, different additives and fillers need to be added during the mixing process to improve its processing performance, enhance its physical properties, and ensure uniform molecular distribution. The mixing process helps to fully utilize the performance of PFE rubber, ensuring that it has excellent elasticity, strength, and corrosion resistance during use, thereby meeting the standards of high-requirement applications.
[0003] Currently, there are various types of perfluoroether rubber compounding and preparation equipment on the market. However, these equipment often suffer from uneven material distribution during the compounding process, especially when processing high-viscosity perfluoroether rubber. Insufficient material mixing leads to inconsistencies in the physical and chemical properties of the rubber. This not only affects the quality of the final product but may also cause material to adhere to the inner wall of the compounding equipment, easily resulting in cross-contamination. The cleaning process is time-consuming and labor-intensive, increasing manual operation costs and reducing production efficiency. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a perfluoroether rubber compounding and preparation apparatus.
[0005] This utility model is achieved by the following technical solution: a perfluoroether rubber compounding preparation device, comprising a transmission mechanism, a protective mechanism and a conveying mechanism, wherein the transmission mechanism is located inside the protective mechanism and the conveying mechanism is located on the surface of the protective mechanism;
[0006] The transmission mechanism includes a drive motor, a gear 1 fixedly connected to the output end of the drive motor, a gear 2 meshing with the surface of the gear 1, a rotating shaft fixedly connected to the bottom of the gear 1, rotating blades fixedly connected to the surface of the rotating shaft, a connecting shaft rotatably connected to the inner wall of the gear 2, a ring fixedly connected to the bottom of the connecting shaft, a scraper fixedly connected to the bottom of the ring, and an auxiliary plate fixedly connected to the inner side of the scraper.
[0007] Through the above technical solution, the cooperation between the auxiliary plate and the rotating blade can further improve the shearing effect of the raw materials, ensure more uniform mixing of materials during the mixing process, and further optimize the mixing efficiency and material handling.
[0008] As a further improvement to the above scheme, the number of gears two is set to two, and the two gears two are symmetrically distributed on the left and right sides with gear one as the center.
[0009] Through the above technical solution, the symmetrically arranged gears can ensure that the rotation of the ring is more stable, thereby driving the scraper to run stably.
[0010] As a further improvement to the above solution, the protective mechanism includes a housing, a sealing cover is fixedly connected to the top of the housing, and the inner wall of the sealing cover is provided with a toothed groove.
[0011] As a further improvement to the above solution, the first gear is located inside the sealing cover, the surface of the second gear meshes with the inner wall of the tooth groove, and the surface of the ring is rotatably connected to the inner wall of the sealing cover.
[0012] Through the above technical solution, the toothed groove on the sealing cover, in conjunction with the rotation of gear two, ensures that during the rotation of gear two, it can drive the connecting shaft to move in a circular motion around gear one, thereby smoothly driving the ring to rotate.
[0013] As a further improvement to the above solution, the rotating shaft is located inside the housing, and the scraper is located outside the rotating shaft.
[0014] As a further improvement to the above solution, the conveying mechanism includes a feed pipe, and a discharge pipe is fixedly connected to the bottom of the housing, with a control valve fixedly connected to the surface of the discharge pipe.
[0015] Through the above technical solutions, the feed pipe and discharge pipe ensure the smooth flow of materials, avoiding damage caused by poor flow or blockage.
[0016] As a further improvement to the above solution, the surface of the feed pipe is fixedly connected to the inner wall of the housing, and the feed pipe is located on the left side of the discharge pipe.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] This invention employs a transmission mechanism where a drive motor rotates gear one, which in turn drives gear two. Since gear one has a smaller diameter than gear two, gear one rotates faster, while gear two rotates slower. Gear two's rotation, through tooth groove meshing with its surface, causes the connecting shaft to rotate around gear one, thus rotating a ring. This ring further drives a scraper to rotate, removing unmixed raw materials adhering to the inner wall, preventing waste during the mixing process. Gear one directly drives a rotating shaft, which in turn rotates a blade. The rapid rotation of the blade shears the raw materials, ensuring uniform mixing with additives. The entire process further improves production efficiency and resource utilization.
[0019] This invention allows raw materials and additives to be fed into the housing through a feed pipe. After thorough shearing and mixing, the material is smoothly conveyed to the discharge pipe for discharge through precise control of the control valve, thereby avoiding blockage or overflow and achieving uniform material output, further improving the stability of the device and production quality.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0028] Example:
[0029] Please combine Figure 1-5 The perfluoroether rubber compounding preparation apparatus of this embodiment includes a transmission mechanism 1, a protective mechanism 2 and a conveying mechanism 3. The transmission mechanism 1 is located inside the protective mechanism 2 and the conveying mechanism 3 is located on the surface of the protective mechanism 2.
[0030] The transmission mechanism 1 includes a drive motor 11. A gear 12 is fixedly connected to the output end of the drive motor 11. A gear 2 13 meshes with the surface of the gear 12. A rotating shaft 14 is fixedly connected to the bottom of the gear 12. A rotating blade 15 is fixedly connected to the surface of the rotating shaft 14. A connecting shaft 16 is rotatably connected to the inner wall of the gear 2 13. A ring 17 is fixedly connected to the bottom of the connecting shaft 16. A scraper 18 is fixedly connected to the bottom of the ring 17. An auxiliary plate 19 is fixedly connected to the inner side of the scraper 18. The cooperation between the auxiliary plate 19 and the rotating blade 15 can further improve the shearing effect of the raw materials, ensure more uniform mixing of materials during the mixing process, and further optimize the mixing efficiency and material handling.
[0031] The number of gears 13 is set to two, and the two gears 13 are symmetrically distributed on the left and right sides with gear 12 as the center. The symmetrical arrangement of gears 13 can ensure that the rotation of ring 17 is more stable, thereby driving scraper 18 to run stably.
[0032] The protective mechanism 2 includes a housing 21, and a sealing cover 22 is fixedly connected to the top of the housing 21. The inner wall of the sealing cover 22 is provided with a toothed groove 23.
[0033] Gear 12 is located inside the sealing cover 22. The surface of gear 23 meshes with the inner wall of the tooth groove 23. The surface of the ring 17 is rotatably connected to the inner wall of the sealing cover 22. The tooth groove 23 on the sealing cover 22, in conjunction with the rotation of gear 23, ensures that during the rotation of gear 23, it can drive the connecting shaft 16 to rotate around gear 12, thereby smoothly driving the ring 17 to rotate.
[0034] The rotating shaft 14 is located inside the housing 21, and the scraper 18 is located outside the rotating shaft 14.
[0035] The conveying mechanism 3 includes a feed pipe 31, and a discharge pipe 32 is fixedly connected to the bottom of the housing 21. A control valve 33 is fixedly connected to the surface of the discharge pipe 32. The feed pipe 31 and the discharge pipe 32 ensure the smooth flow of materials and avoid damage caused by poor flow or blockage.
[0036] The surface of the feed pipe 31 is fixedly connected to the inner wall of the housing 21, and the feed pipe 31 is located to the left of the discharge pipe 32.
[0037] The implementation principle of the perfluoroether rubber compounding preparation device in this embodiment is as follows: The operator puts the raw materials and additives into the housing 21 through the feed pipe 31. Then, the power supply is turned on to start the drive motor 11. The drive motor 11 can drive the gear 12 to rotate. The rotating gear 12 meshes with two gears 13, so it can drive the gears 13 to rotate together. Because the surface of the gears 13 meshes with the inner wall of the tooth groove 23, during the rotation of the gears 13, it can drive the connecting shaft 16 to move in a circle around the gear 12, thereby causing the ring 17 to rotate. The gear 12 can directly drive the rotating shaft 14 to rotate, thereby driving the rotating blade 15 to rotate, thus shearing the raw materials and uniformly mixing them with the additives. The ring 17 can... The scraper 18 is rotated, which scrapes off the raw material adhering to the inner wall of the housing 21, further avoiding waste of resources. Because the diameter of gear 12 is smaller than that of gear 23, the rotation speed of gear 12 is greater than that of gear 23. The rotation speed of the rotating shaft 14 is also higher than that of the scraper 18. The auxiliary plate 19 on the scraper 18 can cooperate with the rotating blade 15 to further improve the shearing effect of the material. At the same time, it can also make the raw material and additives more uniformly mixed. After thorough mixing, the material can be conveyed out from the discharge pipe 32 through the control valve 33. The whole device can ensure that the material is uniformly sheared and mixed while scraping off the raw material adhering to the inner wall of the housing 21, avoiding unnecessary waste and further improving the actual effect.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
