DETAILED DESCRIPTION

[0023] The utility model will be further described below in conjunction with the drawings and specific embodiments. It needs to be explained here that the description of these embodiment modes is used to help understand the utility model, but does not constitute the limitation of the utility model. The specific structure and functional details disclosed in this paper are only used to describe the example embodiment of the utility model. However, the utility model can be embodied in many alternative forms, and should not be understood as being limited in the embodiments set forth herein.

[0024] As Figure 1 shown, Figure 1 The utility model provides the section view of the sealing device with the rotation, and the sealing device with the rotation of the feeding port of the rotary drum machine, the sealing device with the rotation includes driving part 100, sealing piece 200 and connecting piece, wherein:

[0025] As Figure 1 shown, the driving part 100 has the output end 101 that can reciprocate in the set direction, and the driving part 100 is provided with an output end 101 that can reciprocate in the preset direction. To provide the necessary power for sealing piece 200, ensure that sealing piece 200 can be accurately positioned on the feeding port of the rotary drum machine, form effective sealing.

[0026] As Figure 1 shown, sealing piece 200 is used to block the feeding port of the rotary drum machine, and sealing piece 200 is directly contacted with the feeding port of the rotary drum machine, and the main function of sealing piece 200 is to block the leakage of materials from the feeding port when the rotary drum machine works, and keep the closedness of the internal space of the rotary drum machine.

[0027] As Figure 1 shown, the connecting piece is connected between the output end 101 and the sealing piece 200, the connecting piece includes the displacement section 300 fixedly connected with the driving part 100, and the rotating section 400 rotatably connected with the sealing piece 200, the displacement section 300 and the rotating section 400 are provided with the elastic member 500, and the elastic member 500 applies the moving force to the rotating section 400 towards the direction of the rotary drum machine.

[0028] As Figure 1 shown, the displacement section 300 is fixedly connected with the driving part 100, and the rotating section 400 is rotatably connected with the sealing piece 200. To allow sealing piece 200 to rotate with the rotation of the rotary drum machine, while keeping linkage with the driving part 100. The elastic member 500 is arranged between the displacement section 300 and the rotating section 400, and the function of the elastic member 500 is to apply a moving force to the rotating section 400 towards the direction of the rotary drum machine. So that sealing piece 200 can continuously keep the resistance to the rotary drum machine during rotation, even in the case of continuous rotation of the rotary drum machine, the stable rotation of sealing piece 200 can be kept through the deformation recovery force of the elastic member 500.

[0029] When the drum machine starts operating, the drive unit 100 drives the seal 200 to move to the target position through its output end 101, so as to block at the feed inlet and form a seal. Since the drum machine is in a continuous rotating state, the relative rotation between the rotating section 400 of the connecting member and the seal 200, and the contact between the seal 200 and the feed inlet, are maintained by the drum machine through friction to keep the seal 200 rotating stably.

[0030] In an optional embodiment, the working principle of the rotary sealing device in this application is as follows: The rotary sealing device includes a driving member 100, a sealing member 200, and a connecting member. The driving member 100 has an output end 101 that can reciprocate in a set direction. The sealing member 200 is used to block the feed inlet of the rotary drum machine. The connecting member connects the output end 101 and the sealing member 200. The connecting member includes a displacement section 300 fixedly connected to the driving member 100 and a rotating section 400 rotatably connected to the sealing member 200. An elastic member 500 is provided between the displacement section 300 and the rotating section 400. The elastic member 500 applies a force to the rotating section 400 to move towards the rotary drum machine. When the rotary drum machine is actually operating, the rotary drum machine rotates at a set relative position. In this process, the drive component 100 drives the sealing component 200 to abut at the feed inlet, forming a seal at the feed inlet. Since the drum machine is in a continuous rotating state, the relative rotation between the rotating section 400 and the sealing component 200 keeps the sealing component 200 against the feed inlet. The friction force keeps the sealing component 200 rotating stably. At the same time, the drive component 100 continuously outputs a holding force, which is transmitted to the sealing component 200 through the displacement section 300, the elastic component 500, and the rotating section 400. The elastic component 500, through deformation recovery force, ensures that the sealing component 200 continuously maintains a holding force against the drum machine during rotation. This maintains a stable sealing effect and avoids dynamic wear between the sealing component 200 and the drum machine, improving operational reliability, extending service life, and contributing to operational stability and environmental protection.

[0031] like Figure 1 As shown, in an optional embodiment, the displacement segment 300 is provided with a connection hole 301 for accommodating the output end 101. The main function of the connection hole 301 is to accommodate the output end 101 of the drive component 100. This ensures that the output end 101 can be firmly fixed to the displacement segment 300, preventing displacement or detachment during drum machine operation, thereby guaranteeing that the seal 200 can be continuously and stably subjected to the driving force.

[0032] like Figure 1As shown, in an optional embodiment, a detachable positioning pin 302 is arranged through the displacement section 300, which extends into the connecting hole 301 and is used to pass through the output end 101 for connecting the output end 101.

[0033] A detachable positioning pin 302 is also arranged through the displacement section 300. The positioning pin 302 not only enhances the stability of the connection, but also provides a convenient disassembly function to facilitate maintenance or replacement of parts when needed. The positioning pin 302 extends into the connecting hole 301 and directly passes through the output end 101 of the driving member 100, thereby achieving the fixation of the output end 101. This connection method is not only simple and reliable, but also makes the assembly and maintenance of the entire device more convenient and efficient due to the detachability of the positioning pin 302.

[0034] The connecting hole 301 and the positioning pin 302 on the displacement section 300 work together to ensure that the connection between the output end 101 of the driving member 100 and the displacement section 300 is both firm and flexible. Considering the convenience and practicality in actual operation, the rotary sealing device is more efficient and durable in actual application.

[0035] As shown, Figure 1 in an optional embodiment, the rotating section 400 is connected to the sealing member 200 through a bearing seat 403, so that the sealing member 200 and the rotating section 400 can rotate coaxially.

[0036] Specifically, the rotating section 400 and the sealing member 200 are connected through a bearing seat 403. The bearing seat 403 provides stable support, allowing the sealing member 200 and the rotating section 400 to rotate synchronously around the same axis, which is crucial for maintaining the stability of the sealing member 200 and extending its service life.

[0037] Coaxial rotation can reduce vibration and noise during operation, ensure good contact between the sealing member 200 and the inlet of the rotary drum, improve the sealing effect, and reduce material leakage. The bearing seat 403 can reduce direct friction between the sealing member 200 and the rotating section 400, reduce wear and tear, and extend the service life of the components.

[0038] As shown, Figure 1 in an optional embodiment, the displacement section 300 is provided with a first cavity 303 on the side close to the rotating section 400, the end of the rotating section 400 away from the sealing member 200 extends into the first cavity 303, and the elastic member 500 is arranged in the first cavity 303.

[0039] Specifically, the displacement section 300 is provided with a first cavity 303 on one side close to the rotating section 400. The first cavity 303 not only provides an extended space for the rotating section 400, but also provides a position for arranging the elastic member 500. The rotating section 400 extends into the first cavity 303 from the end away from the sealing member 200. This makes the rotating section 400 more deeply interact with the displacement section 300, and also provides a space for fixing and acting on the elastic member 500. The elastic member 500 is arranged in the first cavity 303, which is conducive to the elastic member 500 exerting a stable acting force on the rotating section 400, and also facilitates the maintenance and replacement of the elastic member 500.

[0040] As shown in the optional embodiment, a detachable end cover 304 is arranged on the displacement section 300, the end cover 304 is sleeved on the rotating section 400, and is used to limit the rotating section 400 from being pulled out of the first cavity 303. Figure 1

[0041] In order to further ensure the stability of the rotating section 400 and protect the elastic member 500, the detachable end cover 304 is arranged on the displacement section 300. The end cover 304 is sleeved on the rotating section 400, and the end cover 304 limits the rotating section 400 from being pulled out of the first cavity 303, ensuring the safety and reliability of the entire device. The end cover 304 also considers the convenience of disassembly, so that when the rotating section 400 or the elastic member 500 needs to be maintained, the end cover 304 can be quickly disassembled for necessary operation.

[0042] As shown in the optional embodiment, a detachable end cover 304 is arranged on the displacement section 300, the end cover 304 is sleeved on the rotating section 400, and is used to limit the rotating section 400 from being pulled out of the first cavity 303. Figure 1

[0043] The rotating section 400 is also specially provided with the first step portion 401 and the second step portion 402. The outer periphery of the first step portion 401 is in close contact with the inner wall of the first cavity 303, which helps to fix the relative position of the rotating section 400 and prevent unnecessary deviation of the rotating section 400 in the first cavity 303. The end cover 304 is arranged on one side of the end surface of the first step portion 401, which further enhances the stability of the rotating section 400. The outer diameter of the second step portion 402 is smaller than that of the first step portion 401, so as to provide a suitable sleeving position for the elastic member 500, so that the elastic member 500 can stably sleeve on the second step portion 402 to play a role. ​​

[0044] The first cavity 303 and the end cap 304 not only protect the elastic element 500, but also enhance the stability of the rotating section 400; while the first step portion 401 and the second step portion 402 provide a stable working environment for the elastic element 500, and also improve the convenience of assembly and maintenance of the entire device.

[0045] like Figure 1 As shown, in an optional embodiment, the sealing element 200 is provided with an annular retaining strip 201, the inner diameter of which is larger than the feed inlet of the drum machine.

[0046] Specifically, the seal 200 is provided with an annular retaining strip 201, which helps to enhance the fit between the seal 200 and the feed inlet of the drum machine. The inner diameter of the annular retaining strip 201 is designed to be larger than the feed inlet of the drum machine, so that the seal 200 can cover and extend beyond the edge of the feed inlet, thereby providing an additional barrier layer to prevent material from leaking from the edge of the feed inlet.

[0047] In an optional embodiment, the seal 200 is provided with a rubber layer. The rubber layer has good elasticity and wear resistance, and can adapt to different working environments and temperature changes. The rubber layer can provide a better sealing effect because it can fit tightly against the feed inlet of the drum machine. Even when the drum machine vibrates or moves slightly, the rubber layer can maintain good contact with the feed inlet, reducing the risk of material leakage.

[0048] In an optional embodiment, the seal 200 is made of a rubber sheet. In another optional embodiment, the seal 200 uses a rubber sheet as the primary material. The use of a rubber sheet offers several advantages, including high elasticity, good abrasion resistance, and resistance to chemical corrosion.
