[0002] Fluororubber has excellent heat resistance, oxidation resistance, oil resistance, corrosion resistance and atmospheric aging resistance, and is widely used in aerospace, aviation, automotive, petroleum and household appliances. In the production of fluororubber, after stirring and washing, the raw rubber material needs to be washed and dehydrated before it can be transported to the subsequent production line.

[0003] Existing fluororubber dehydration structures only squeeze out the water from the fluororubber through screw extrusion, resulting in low dehydration efficiency and requiring multiple raw material inputs for processing, leading to long dehydration times. Utility Model Content

[0010] Preferably, the top end of the driving pressure ring, the upper and lower ends of the driven pressure ring, and the four corners of the fixed pressure ring are all fixedly connected with connecting ears.

[0011] Preferably, an extension plate is fixedly connected to the bottom of the driving pressure ring, and a through hole is provided on the extension plate corresponding to the rocking movable rod. A ring is fixedly connected to the bottom of the extension plate. The fixed ears at the top of the driving pressure ring and the driven pressure ring are inserted into the vertical movable rod, and the through hole and the fixed ears at the top and bottom of the driven pressure ring are inserted into the rocking movable rod.

[0012] Preferably, the fixed pressure ring is rotatably connected to the rocker arm via a connecting lug.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

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.

[0025] Reference Figure 1-6 A rapid dehydration structure for fluororubber includes a housing 1, an inlet 2 at the top of one end of the housing 1, an outlet 3 on the side wall of the other end of the housing 1, an installation plate 4 inside the housing 1, a filter cartridge 5 between the installation plates 4, a coiling tube 6 at the output end of the filter cartridge 5, a conveying screw 7 inside the filter cartridge 5, an output screw inside the housing 1 corresponding to the coiling tube 6, an extrusion assembly on the outer wall of the filter cartridge 5, a swaying assembly at the bottom of the extrusion assembly, a water guiding slope 8 at the bottom of the swaying assembly, and a drain pipe 9 on the outer side of the housing 1 corresponding to the water guiding slope 8.

[0026] By setting up a water guiding slope 8, under the combined action of the water guiding slope 8 and the extrusion assembly, the squeezed water seeps out of the filter cartridge 5 and falls into the water guiding slope 8 to collect, and is then extracted from the equipment by the drain pipe 9, thus realizing the function of recovering squeezed water and saving costs.

[0027] It should be noted that the output screw and drain pipe 9 are existing technologies and will not be described in detail.

[0028] Furthermore, one end of the conveying screw 7 passes through the take-up tube 6 and is fixedly installed with a plug 10, while the other end of the conveying screw 7 passes through the housing 1 and is rotatably connected to the conveying motor 11.

[0029] It should be noted that there is a narrow gap between the plug 10 and the coil tube 6, which requires a certain amount of pressure to extrude the fluororubber.

[0030] Furthermore, the surface of the mounting plate 4 is provided with a vertical groove 12 and a circular hole 13 that match the extrusion assembly.

[0031] Furthermore, the extrusion assembly includes a fixed rod 14, a vertical movable rod 15, and a rocking movable rod 16. Both ends of the fixed rod 14 are fixedly connected to the mounting plate 4. Limiting sliders 17 are fixedly connected to both ends of the vertical movable rod 15 and the rocking movable rod 16. Multiple driving pressure rings 18, driven pressure rings 19, and fixed pressure rings 20 are arranged between the fixed rod 14, the vertical movable rod 15, and the rocking movable rod 16. The top of the driving pressure ring 18, the upper and lower ends of the driven pressure ring 19, and the fixed pressure ring 20... Connecting ears 21 are fixedly connected to all four corners. An extension plate 22 is fixedly connected to the bottom of the drive pressure ring 18. A through hole 23 is provided on the extension plate 22 corresponding to the swing rod 16. A ring 24 is fixedly connected to the bottom of the extension plate 22. The fixed ears on the top of the drive pressure ring 18 and the driven pressure ring 19 are inserted into the vertical moving rod 15. The through hole 23 and the fixed ears on the top and bottom of the driven pressure ring 19 are inserted into the swing rod 16. The fixed pressure ring 20 is rotatably connected to the swing rod 16 through the connecting ears 21.

[0032] It should be noted that: the driving pressure ring 18, the driven pressure ring 19, and the fixed pressure ring need to be as follows: Figure 6 The staggered arrangement shown is designed to achieve the best compression effect.

[0033] The further advantage of the above-mentioned method is that, during the conveying process of the rubber, the drive pressure ring 18 is driven by the rotating block 26 to perform a pendulum motion, and the driven pressure ring 19 is driven by the drive pressure ring 18 to move synchronously. The fixed pressure ring 20 does not move with the drive pressure ring 18. Through the combined action of the drive pressure ring 18, the driven pressure ring 19 and the fixed pressure ring 20, the filter cylinder 5 and the fluororubber inside the filter cylinder 5 are continuously and evenly squeezed during the conveying process, thereby improving the dewatering efficiency and speed.

[0034] Furthermore, the rocking assembly includes a rotating rod 25, a rotating block 26 is provided at the position of the rotating rod 25 corresponding to the ring 24, and a roller 27 is rotatably connected to the rotating block 26 at the position of the ring 24. The roller 27 reduces the friction on the ring 24, thereby improving the service life of the ring 24. One side of the rotating rod 25 is rotatably connected to the mounting plate 4, and the other side of the rotating rod 25 passes through the mounting plate 4 and is connected to the rocking motor 28.

[0035] In use, fluororubber raw rubber is added through the feed inlet 2. After entering, the raw rubber is output by the conveying screw 7 and slowly advances into the filter cartridge 5. Simultaneously, the swing motor 28 drives the rotating rod 25 to rotate. When the rotating rod 25 rotates, it drives the rotating block 26 to rotate within the ring 24 and applies forces in multiple directions. The rotating block 26 pushes the ring 24 through the roller 27. After the driving pressure ring 18 is subjected to force, it drives the vertical movable rod 15 to slide vertically within the vertical slide groove 12 through the limiting slider 17. At the same time, it drives the swing movable rod 16 to rotate along the circular hole 13 through the limiting slider 17, thereby causing the drive to... The dynamic pressure ring 18 performs a pendulum motion, which drives the driven pressure ring 19 to move synchronously. The fixed pressure ring 20 does not move with the driving pressure ring 18. Through the combined action of the driving pressure ring 18, the driven pressure ring 19, and the fixed pressure ring 20, the filter cylinder 5 and the fluororubber inside the filter cylinder 5 are continuously and evenly squeezed during conveying, thereby improving the dewatering efficiency and speed. The squeezed water seeps out of the filter cylinder 5 and falls into the water guide slope 8 to collect. It is then extracted from the equipment by the drain pipe 9, realizing the function of recovering the squeezed water and saving costs. The squeezed fluororubber is discharged from the discharge port 3 through the output worm gear.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
