Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Reference Figure 2 - Figure 3 The screening component 3 includes a filter shell 1 31. The filter shell 1 31 and the filter shell 2 32 have the same number of filter holes, and the filter holes correspond one to one. When the filter shell 2 32 is rotated, its filter holes will be misaligned with the filter holes of the filter shell 1 31, so as to achieve the purpose of adjusting the size. The bottom end of the filter shell 1 31 contacts the inner wall of the rotating plate 4. The inner wall of the filter shell 1 31 is rotatably connected to the filter shell 2 32. The fixed shell 1 52 is fixedly connected to the bottom end of the right surface of the filter shell 1 31.

[0035] Reference Figure 3 , Figure 5 The fixing assembly 5 also includes a fixing shell 2 53, which is fixedly connected to the top of the right surface of the filter shell 1 31. A bolt 54 is threadedly connected to the right surface of the fixing shell 2 53. The bolt 54 is adapted to the groove to ensure the stability of the connection. The left end of the bolt 54 is threadedly connected to the inner wall of the groove.

[0036] Reference Figure 3 , Figure 6 A block 56 is slidably connected to the front surface of the fixed shell 52, and the front end of the block 56 contacts the inner wall of the rectangular groove 7. A slide plate 57 is fixedly connected to the lower surface of the rear end of the block 56. The slide plate 57 is slidably connected to the inner wall of the rectangular groove 59. There are multiple groups of slide plates 57, and the multiple groups of slide plates 57 are elastically connected by springs 58. The springs 58 always pull the multiple groups of block blocks 56 toward the inner wall of the fixed shell 52 through their own elasticity, ensuring that when the wedge block 55 releases the squeeze on the block 56, the block 56 can quickly release the limit. One end of the spring 58 is fixedly connected to the rear surface of the slide plate 57, and the other end of the spring 58 is fixedly connected to the front surface of the multiple groups of slide plates 57. The block 56 is a trapezoidal block, and the rear surface is set to an inclined surface. The set inclined surface ensures that the block 56 can be squeezed and moved smoothly.

[0037] Reference Figure 3 , Figure 4 The upper surface of the filter shell 31 is rotatably connected to a rotating block 34, and the right surface of the rotating block 34 is threadedly connected to a threaded rod 35. The threaded rod 35 is a prior art, which is a rod-shaped structure with a thread on the outer wall. When rotating, the rectangular block 33 will move linearly, and it has the characteristics of left and right self-locking to ensure the stability of the structural connection. The outer wall of the threaded rod 35 is threadedly connected to a rectangular block 33, and the rectangular block 33 is rotatably connected to the upper surface of the filter shell 32.

[0038] Working principle: when in use, the rubber is placed on the inner wall of the filter shell 32 and the rotating plate 4 is driven to rotate by the motor. The rotating plate 4 will drive the screening component 3 to rotate through the fixing component 5. The centrifugal force generated by the rotation can separate the rubber from the impurities. When the size of the screening holes of the filter shell 1 31 and the filter shell 2 32 needs to be adjusted according to the size of the rubber, the threaded rod 35 can be rotated, which will cause the rectangular block 33 threadedly connected to its outer wall to move. At this time, the filter shell 2 32 will rotate on the inner wall of the filter shell 1 31, and the rectangular block 33 will rotate on the upper surface of the filter shell 2 32. At the same time, the rotating block 34 will also rotate on the upper surface of the filter shell 1 31 to adjust its position to ensure that the filter shell 2 32 can rotate smoothly. In this way, the holes of the filter shell 2 32 will be misaligned with the holes of the filter shell 1 31, so that the size of the screening can be controlled.

[0039] When the screening assembly 3 needs to be removed, the bolt 54 is turned to release the fixing of the push plate 51. At this time, the push plate 51 is pulled, and the push plate 51 will drive the wedge block 55 to move, and the wedge block 55 will move away from the block 56. At the same time, the spring 58 will drive the slide plate 57 to move, and the slide plate 57 will drive the block 56 to move until the block 56 is completely separated from the inner wall of the rectangular groove 7. In this way, the screening assembly 3 can be removed. When installing, it is only necessary to place the screening assembly 3 on the inner wall of the sealing cover plate 1 and put the fixing shell 1 52 on the inner wall of the sealing cover plate 1. The push plate 51 then pushes back the wedge block 55, which moves along with the inclined surface of the wedge block 55 and cooperates with the inclined surface of the card block 56 to push the multiple card blocks 56 to move. The multiple card blocks 56 drive the slide plate 57 to move and stretch the spring 58 until the push plate 51 cannot be pushed. At this time, the card block 56 enters the inner wall of the rectangular groove 7, and the bolt 54 overlaps with the groove on the right surface of the top of the push plate 51. The screening assembly 3 can be fixed by reversing the bolt 54.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
