[0023] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described below.

[0024] To address the problems existing in the background technology, this application proposes the following technical solution: a feeding device for the production of fluorosilicone seals, including a frame 1, an outer cylinder 5 on the frame 1, and a screw conveyor 2 at the bottom of the frame 1 (the screw conveyor 2 is an existing product). A screening cylinder 20 is fixedly connected inside the outer cylinder 5, and the screening cylinder 20 has multiple sets of screening holes for screening the crushed material. A rotating shaft 21 is rotatably connected inside the screening cylinder 20, and multiple sets of crushing blades 22 are fixedly connected to the outside of the rotating shaft 21. A first motor 9 is fixedly connected to the outside of the outer cylinder 5, and the output end of the first motor 9 is fixedly connected to the rotating shaft 21. The first motor 9 is used to drive the rotating shaft 21 to rotate, and the rotating shaft 21 drives the crushing blades 22 to rotate, thereby fully crushing the material.

[0025] In a further design, a sliding sealing assembly is provided on the outside of the outer cylinder 5. The sliding sealing assembly consists of a sliding plate 14 and a through hole 15 on the outside of the sliding plate 14. A threaded rod 16 is rotatably connected inside the first horizontal frame 11, and a nut block 17 is threadedly connected to the outside of the threaded rod 16. A guide rod 18 is fixedly connected inside the second horizontal frame 13, and a second motor 12 is fixedly connected to the outside of the first horizontal frame 11. The output end of the second motor 12 is fixedly connected to the threaded rod 16. The nut block 17 is fixedly connected to the sliding plate 14. A sliding sleeve is fitted on the outside of the guide rod 18, and the sliding sleeve is fixedly connected to the sliding plate 14. When the through hole 15 corresponds to the outer cylinder 5, the material can be added into the screening cylinder 20. When crushing is required, the second motor 12 drives the threaded rod 16 to rotate, so that the nut block 17 drives the sliding plate 14 to slide, so that the solid area of ​​the sliding plate 14 corresponds to the outer cylinder 5, thus sealing the outer cylinder 5.

[0026] The outer cylinder 5 and the screening cylinder 20 are both open at one end, and the diameter of the through hole 15 is greater than or equal to the diameter of the outer cylinder 5.

[0027] The bottom of the outer cylinder 5 is fixedly connected to a discharge hopper 19, the bottom of the discharge hopper 19 is fixedly connected to a corrugated pipe 4, the bottom of the corrugated pipe 4 is fixedly connected to a feed pipe 3, the feed pipe 3 is fixedly connected to the feed inlet of the screw conveyor 2, and the frame 1 is also provided with a support adjustment component to support the outer cylinder 5.

[0028] In other designs, the corrugated pipe 4 can also be replaced by a rubber hose. The rotation of the outer cylinder 5 can be adjusted by using the rubber hose or the corrugated pipe 4.

[0029] In a further design, a fixing frame 10 is fixedly connected to the outside of the outer cylinder 5, and a first horizontal frame 11 and a second horizontal frame 13 are fixedly connected to the top and bottom of the fixing frame 10, respectively.

[0030] Specifically, the support and adjustment components include a rotating rod 6 rotatably connected to the frame 1 and a hydraulic cylinder 8 hinged to the outside of the frame 1. The rotating rod 6 is fixedly connected to the outer cylinder 5. An adjusting arm 7 is hinged to the output end of the hydraulic cylinder 8. The adjusting arm 7 is fixedly connected to the rotating rod 6. The hydraulic cylinder 8 drives the adjusting arm 7 to rotate, thereby adjusting the angle of the outer cylinder 5. On the one hand, this allows the material to move inside the screening cylinder 20, allowing the crushing blade 22 to fully crush it. On the other hand, it accelerates the screening of the material inside the screening cylinder 20.

[0031] The specific operation procedure in this embodiment is as follows:

[0032] The material to be crushed is poured into the screening cylinder 20. The second motor 12 is started to drive the threaded rod 16 to rotate, so that the nut block 17 drives the slide plate 14 to slide, so that the solid area of ​​the slide plate 14 corresponds to the outer cylinder 5. Then the first motor 9 is started to drive the rotating shaft 21 to rotate. The rotating shaft 21 drives the crushing blade 22 to crush the material. The crushed material is screened through the screening cylinder 20 and enters the feed pipe 3. Then it is conveyed by the screw conveyor 2.

[0033] At the same time, the hydraulic cylinder 8 can be activated to drive the adjusting arm 7 to rotate, thereby adjusting the angle of the outer cylinder 5. On the one hand, this allows the material to move inside the screening cylinder 20, allowing the crushing blade 22 to fully crush it. On the other hand, it can accelerate the screening of the material inside the screening cylinder 20.

[0034] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
