Abstract
Description
Technical Field
[0001] This utility model relates to the field of vulcanizing tank technology, specifically a sealing structure for the opening of a vulcanizing tank. Background Technology
[0002] In the production of rubber, plastic, and other products, vulcanization is a crucial step, and the vulcanizing tank is the core equipment for achieving this process. The sealing performance of the vulcanizing tank opening directly affects the quality and safety of the vulcanization process.
[0003] Traditional vulcanizing tank opening seals are relatively simple, typically relying on a single sealing strip. However, this simple sealing method has several drawbacks in practical use. Firstly, with increased use of the vulcanizing tank, the sealing strip is prone to wear and aging due to repeated friction and high-temperature environments, leading to decreased sealing performance and potential leakage of the vulcanizing medium. This not only wastes energy and increases production costs but may also pollute the production environment and even threaten the lives of operators. Secondly, traditional sealing structures are not sufficiently secure in their connection between the sealing door and the vulcanizing tank body. During vulcanization, high pressure and temperature are generated inside the tank; if the sealing door is not securely connected, it is prone to loosening and opening, severely affecting the quality of the vulcanized products and even causing the entire vulcanization process to fail. Furthermore, some existing vulcanizing tank opening seals are complex to operate, with opening and closing the sealing door being time-consuming and labor-intensive, reducing production efficiency. Therefore, we propose a new sealing structure for the vulcanizing tank opening. Utility Model Content
[0004] The purpose of this invention is to provide a sealing structure for the opening of a vulcanizing tank to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a vulcanizing tank, with several supports evenly fixedly installed at the bottom of the vulcanizing tank. An installation frame is fixedly installed on the outer wall of one side of the front end of the vulcanizing tank. A rotating shaft is rotatably mounted on the installation frame via a bearing, and a sealing door is fixedly installed on the rotating shaft. A first sealing strip is fixedly installed on the outer wall of the front end of the vulcanizing tank, and a second sealing strip is fixedly installed on the inner wall of the sealing door. An installation shell is fixedly installed on the outer wall of the other side of the front end of the vulcanizing tank. A sliding rod is fixedly installed inside the installation shell. A locking block is fixedly installed on the sealing door. An opening for the locking block to enter is provided on the side wall of the installation shell. A sliding plate is slidably mounted on the sliding rod, and an insertion rod is fixedly installed at the bottom of the sliding plate. An insertion hole for cooperation with the insertion rod is provided on the locking block. A threaded rod is rotatably mounted inside the installation shell, penetrating the sliding plate and threadedly connected to it.
[0006] Preferably, a mounting shaft is rotatably disposed inside the lower part of the mounting housing. The mounting shaft is connected to a threaded rod via a bevel gear transmission mechanism. A worm gear is connected to the mounting shaft via a key. A worm is also rotatably disposed on the mounting housing, and the worm and the worm gear mesh with each other.
[0007] Preferably, the bevel gear transmission mechanism includes a first bevel gear connected to the mounting shaft via a key, and a second bevel gear connected to the threaded rod via a key, the second bevel gear meshing with the first bevel gear.
[0008] Preferably, the card block also has an installation cavity inside, a telescopic rod is fixedly installed inside the installation cavity, a slider is fixedly installed at the end of the telescopic arm of the telescopic rod, a limit rod is fixedly installed on the slider, and a limit groove is provided on the insertion rod to cooperate with the limit rod.
[0009] Preferably, a return spring is sleeved on the outer side of the telescopic rod, one end of the return spring is fixedly connected to the slider, and the other end of the return spring is fixedly connected to the inner wall of the mounting cavity.
[0010] Preferably, a handle is fixedly installed at the outer end of the worm gear.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a first sealing strip on the outer wall of the front side of the vulcanizing tank and a second sealing strip on the inner wall of the sealing door, the two are tightly fitted when the sealing door is closed, which effectively improves the sealing effect of the tank opening, prevents leakage of the vulcanizing medium, avoids energy waste and environmental pollution, ensures production safety, and reduces product quality problems caused by poor sealing. At the same time, after the locking block on the sealing door enters the mounting shell, the worm gear is driven by rotating the handle, and the threaded rod is rotated through the worm wheel, mounting shaft and bevel gear transmission mechanism, which in turn drives the sliding plate and the insertion rod to insert into the insertion hole of the locking block, realizing a stable connection between the sealing door and the vulcanizing tank. Moreover, the limiting rod set in the locking block is inserted into the limiting groove of the insertion rod under the action of the telescopic rod and the return spring, which further enhances the connection strength and ensures that the sealing door will not loosen or open due to changes in pressure and temperature inside the tank during the vulcanizing process, thus ensuring the quality of the vulcanized products.
[0012] In addition, thanks to the self-locking function of the worm gear and the simple transmission structure, workers can easily open and close the sealing door by simply turning the handle. The operation is simple and labor-saving, effectively improving production efficiency. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] This utility model provides a technical solution: such as Figures 1-4 The diagram illustrates a sealing structure for the opening of a vulcanizing tank, comprising a vulcanizing tank 1. A mounting frame 3 is fixedly installed on the outer wall of one side of the front end of the vulcanizing tank 1. A rotating shaft is rotatably mounted on the mounting frame 3 via a bearing. A sealing door 4 is fixedly installed on the rotating shaft. A first sealing strip 5 is fixedly installed on the outer wall of the front end of the vulcanizing tank 1, and a second sealing strip 6 is fixedly installed on the inner wall of the sealing door 4. Under the action of the first sealing strip 5 and the second sealing strip 6, the sealing door 4 seals the vulcanizing tank 1, thereby improving the sealing performance of the vulcanizing tank 1 and ensuring its efficiency. Several supports 2 are also evenly fixedly installed at the bottom of the vulcanizing tank 1. Under the action of the supports 2, the stability of the vulcanizing tank 1 during actual use is ensured, thereby ensuring the efficiency of the vulcanizing tank 1.
[0020] An installation shell 7 is fixedly installed on the outer wall of the other side of the front end of the vulcanizing tank 1. A sliding rod 9 is fixedly installed inside the installation shell 7. A locking block 8 is fixedly installed on the sealing door 4. An opening is provided on the side wall of the installation shell 7 for the locking block 8 to enter. A sliding plate 10 is slidably mounted on the sliding rod 9. An insertion rod 11 is fixedly installed at the bottom of the sliding plate 10. An insertion hole is provided on the locking block 8 to cooperate with the insertion rod 11. At this time, under the action of the insertion rod 11 and the insertion hole, the connection quality between the locking block 8 and the installation shell 7 is ensured, thereby ensuring the connection quality between the sealing door 4 and the vulcanizing tank 1. A threaded rod 12 is also rotatably mounted inside the installation shell 7. The threaded rod 12 passes through the sliding plate 10 and is threadedly connected to the sliding plate 10. At this time, rotating the threaded rod 12 can drive the sliding plate 10 to move up and down inside the installation shell 7, thereby facilitating the insertion of the insertion rod 11 into the insertion hole or the removal of the insertion rod 11 from the insertion hole, thereby ensuring the connection quality between the sealing door 4 and the vulcanizing tank 1.
[0021] An installation shaft 13 is rotatably mounted inside the lower part of the mounting housing 7. The installation shaft 13 is connected to the threaded rod 12 via a bevel gear transmission mechanism. The bevel gear transmission mechanism includes a first bevel gear 14 connected to the installation shaft 13 via a key, and a second bevel gear 15 connected to the threaded rod 12 via a key. The second bevel gear 15 meshes with the first bevel gear 14. Rotating the installation shaft 13 will drive the threaded rod 12 to rotate via the first bevel gear 14 and the second bevel gear 15. A worm gear 16 is connected to the installation shaft 13 via a key, and a worm 17 is rotatably mounted on the mounting housing 7. The worm 17 meshes with the worm gear 16. Rotating the worm 17 will drive the installation shaft 13 to rotate via the worm gear 16. In addition, because the worm gear 16 and the worm 17 have a self-locking function, the position of the inserted rod 11 after adjustment can be restricted, thereby ensuring the connection quality between the sealing door 4 and the vulcanizing tank 1. A handle 18 is fixedly mounted on the outer end of the worm 17. Rotating the handle 18 will drive the worm 17. The rotation makes it easier for staff to open the sealed door 4.
[0022] The card block 8 also has an installation cavity 19 inside, and a telescopic rod 20 is fixedly installed inside the installation cavity 19. A slider 21 is fixedly installed at the end of the telescopic arm of the telescopic rod 20. A limit rod 22 is fixedly installed on the slider 21. A limit groove is opened on the insertion rod 11 to cooperate with the limit rod 22. At this time, under the action of the limit rod 22 and the limit groove, the connection quality between the card block 8 and the installation shell 7 is further improved, thereby better ensuring the connection quality between the sealing door 4 and the vulcanizing tank 1. A return spring 23 is sleeved on the outside of the telescopic rod 20. One end of the return spring 23 is fixedly connected to the slider 21, and the other end of the return spring 23 is fixedly connected to the inner wall of the installation cavity 19. At this time, under the action of the return spring 23, the connection quality between the limit rod 22 and the limit groove is ensured.
[0023] Working principle: Initially, the sealing door 4 is in the open state. When it needs to be closed, the sealing door 4 is rotated around the mounting bracket 3 by the rotating shaft, so that it is close to the front end of the vulcanizing tank 1. The first sealing strip 5 and the second sealing strip 6 fit together to improve the sealing performance. The bracket 2 ensures the stability of the vulcanizing tank 1.
[0024] Next, the sealing door 4 is fixed. Rotating the handle 18 drives the worm gear 17 to rotate, which meshes with the worm wheel 16, causing the mounting shaft 13 to rotate. The mounting shaft 13, via a keyed first bevel gear 14, meshes with the second bevel gear 15 on the threaded rod 12, causing the threaded rod 12 to rotate. The threaded rod 12 is threadedly connected to the sliding plate 10, causing the sliding plate 10 to move downwards along the sliding rod 9, driving the insertion rod 11 into the insertion hole of the locking block 8. Simultaneously, the slider 21 inside the locking block 8, under the action of the return spring 23, causes the telescopic rod 20 to extend and push the limiting rod 22 into the limiting groove of the insertion rod 11, further improving the connection quality. The self-locking function of the worm wheel 16 and the worm gear 17 restricts the position of the insertion rod 11. To open, rotating the handle 18 in the opposite direction, through the above transmission, causes the insertion rod 11 to move out of the insertion hole, and the limiting rod 22 also resets under the action of the return spring 23, allowing the sealing door 4 to be rotated to open the vulcanizing tank 1.
