Alternatively, as shown in fig. 2, the orthographic projection of the sealing member 32 on the fixing plate 31 is located within the outline of the fixing plate 31.

Specifically, the fixing plate 31 and the sealing member 32 each have an annular structure, and the shape of the annular structure may be a circular ring, a rectangular ring, an elliptical ring, or other geometric shapes. The orthographic projection of the sealing member 32 on the fixing plate 31 is located within the outline of the fixing plate 31, which means that when the sealing member 32 and the fixing plate 31 are both circular rings, the outer diameter of the fixing plate 31 is larger than the outer diameter of the sealing member 32, and the inner diameter of the fixing plate 31 is smaller than the inner diameter of the sealing member 32, and when the sealing member 32 or the fixing plate 31 is in other geometrical ring-shaped structure, the fixing plate 31 can completely cover the sealing member 32.

When the number of the fixing blocks 332 is two, the two fixing blocks 332 are distributed on the same radial direction of the rotating pipe 2, and when the number of the fixing blocks 332 is at least three, the included angles between the two adjacent fixing blocks 332 are equal, so that the plurality of fixing blocks 332 are uniformly distributed on the outer wall of the rotating pipe 2 along the circumferential direction of the rotating pipe 2.

Thus, on one hand, compared with the fixing block 332 which is arranged in a whole annular structure, the material consumption of the fixing block 332 can be saved, and the cost is reduced; on the other hand, when there is a large deviation of parallelism between the fixed tube 1 and the rotary tube 2 or the upper end surface of the rotary tube 2 is not parallel to the lower end surface of the fixed plate 31 so that a gap is generated at a partial position between the sealing member 32 and the fixed plate 31, the gap between the sealing member 32 and the fixed plate 31 can be eliminated by tightening the pressing members 333 near the position where the gap is located without adjusting all the pressing members 333, so that the adjustment process is pertinent and efficient.

In this embodiment, the horizontal portion 3312 abuts both the sealing member 32 and the pressing member 333 as an abutting portion of the pressing plate 331, and the vertical portion 3311 abuts the outer side surface of the sealing member 32 as a stopper to prevent the sealing member 32 from being largely deformed in the horizontal direction. Like this, when adopting packing class softwood material to seal as sealing member 32 winding on the rotating tube 2, vertical portion 3311 can prevent that the winding packing from taking place dislocation deformation and leading to the packing pine to take off when receiving the extrusion effort of vertical direction to further guarantee that sealing device 3 can effectively seal.

Alternatively, as shown in connection with fig. 2, the vertical portion 3311 is provided spaced apart from the fixing plate 31 in the vertical direction.
