[0002] A head is a component of a container, specifically a boiler component within a pressure vessel. It is typically used to connect the two ends of a pressure vessel to the cylinder by welding. It is also used as a welded pipe fitting to seal the end of a pipeline.

[0003] In the manufacturing process of pressure vessels, storage tanks and other equipment, the end cap is a key sealing component. The quality of its fit with the inner lining directly affects the sealing performance and safety of the equipment. Edge pressing is the core link to ensure this quality. When pressing the edges of end caps of different specifications, the pressing components of the pressing device need to be able to accurately match their size parameters in order to ensure tight edge sealing and uniform pressing.

[0004] Traditional end cap pressing devices often employ fixed structures or require complex disassembly and adjustment to adapt to different end caps. Different specifications of end caps require the replacement of pressing components of corresponding sizes, which not only increases equipment costs and spare parts inventory but also necessitates frequent downtime for replacement, severely impacting production efficiency. Therefore, it is necessary to provide a pressing device that can be quickly adjusted to improve the applicability and production efficiency of the pressing device. Utility Model Content

[0005] The purpose of this utility model is to provide a sealing and pressing device for the edge of the end cap liner, thereby solving the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a sealing and pressing device for the inner lining layer of a head, comprising:

[0007] The control panel, the fixed frame, and the pressure plate are provided. The fixed frame is fixed to the middle of the upper surface of the control panel, and the pressure plate is installed at the center of the fixed frame.

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.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] Please see Figure 1-4 As shown, this utility model is a sealing and pressing device for the inner lining layer of a head, comprising:

[0030] The control panel 11, the fixed frame 12 and the pressure plate 13 are provided. The fixed frame 12 is fixed to the middle of the upper surface of the control panel 11, and the pressure plate 13 is installed at the center of the fixed frame 12.

[0031] The operating table 11 serves as the basic support platform for the entire device. The fixed frame 12 is used to install and fix the pressure plate 13 and provide stable support for the pressure plate 13. During the pressing process, the pressure plate 13 firmly fixes the end cap to the operating table 11 through its own pressure, preventing the end cap from shifting or warping due to edge pressure.

[0032] The edge pressing assembly includes a fixed frame 21, a movable column 22, a slot 221, a movable frame 23, and a threaded hole 231. The fixed frame 21 is fixed to the upper surface of the operating table 11. The movable column 22 slides through the inside of the fixed frame 21. The slot 221 is opened on the upper surface of the movable column 22. The movable frame 23 is fixed to one end of the movable column 22. The threaded hole 231 is opened at the center of the upper surface of the movable frame 23.

[0033] The fixed frame 21 is the sliding carrier of the movable column 22. Its internal channel provides a horizontal sliding track for the movable column 22 and restricts the movement direction of the movable column 22. By sliding within the fixed frame 21, the movable column 22 can drive the movable frame 23 and the pressure plate 25 to move closer to or away from the edge of the end cap. When the end of the movable rod 27 is engaged with the slot 221, the movable column 22 can be locked in the current position to prevent it from sliding due to force during the pressing process and to ensure the stability of the pressing position. The movable frame 23 is used to install the threaded rod 24 and support the pressure plate 25. The threaded hole 231 cooperates with the threaded rod 24 and is the key structure for realizing the height adjustment of the pressure plate 25. Through the threaded engagement of the threaded hole 231 and the threaded rod 24, the rotational motion of the threaded rod 24 is converted into vertical up and down motion, thereby precisely controlling the height of the pressure plate 25.

[0034] A threaded rod 24 is rotatably passed through the threaded hole 231, and a pressure plate 25 is fixed at the lower end of the threaded rod 24. The pressure plate 25 is in contact with the outer surface of the end cap. A connecting frame 26 is fixed on the upper surface of the fixing frame 21. A first movable hole 261 is opened at the center of the upper surface of the connecting frame 26, and a second movable hole 262 is opened at the center of the upper surface of the fixing frame 21. The second movable hole 262 is positively corresponding to the first movable hole 261.

[0035] The operator rotates the threaded rod 24, using the characteristics of threaded transmission to drive the pressure plate 25 to move up and down, thereby achieving precise control of the pressing edge height. After the pressure plate 25 is adjusted to the correct horizontal position and height, it uses its own pressure to tightly press the edge of the end cap with the inner lining layer, thus achieving the function of sealing the pressing edge. The connecting bracket 26 is used to install the movable rod 27 and provide it with motion guidance. The first movable hole 261 and the second movable hole 262 are positively aligned and together form the sliding track of the movable rod 27.

[0036] A movable rod 27 is slidably sleeved inside the first movable hole 261 and the second movable hole 262. A baffle 28 is fixed in the middle of the movable rod 27, and a first spring 29 is fixed on one side of the baffle 28. The end of the movable rod 27 extends into the slot 221.

[0037] When the movable rod 27 is pulled upward, its end disengages from the slot 221, releasing the lock on the movable column 22. When the movable rod 27 is pulled upward, the baffle 28 moves upward and compresses the first spring 29, allowing the spring to store elastic potential energy. After the movable rod 27 is released, the baffle 28 drives the movable rod 27 to reset under the action of the spring force, ensuring that the end of the movable rod 27 is tightly engaged with the slot 221.

[0038] Working principle:

[0039] When pressing the edge of the end cap, for different end caps, the operator lifts the movable rod 27 upwards, compressing the first spring 29. The end of the movable rod 27 exits from the slot 221. At this time, the movable column 22 is moved so that the pressure plate 25 contacts the end cap. Then the threaded rod 24 is rotated. The threaded rod 24 rotates in the threaded hole 231, so that the threaded rod 24 moves vertically up and down, so that the pressure plate 25 corresponds to the required pressing height of the end cap.

[0040] This step enables flexible adaptation to end caps of different specifications, which simplifies the operation process, improves adjustment efficiency, and ensures the accuracy and quality of edge pressing, significantly enhancing the practicality of the end cap edge pressing device.

[0041] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0042] The limiting assembly includes a square groove 31, a limiting frame 32, a movable plate 33, and a connecting plate 34. The square groove 31 is opened on both sides of the fixed frame 12. There are two limiting frames 32, which are fixed on the upper surface of the operating table 11 respectively. The movable plate 33 slides through the square groove 31 and the limiting frame 32. The connecting plate 34 is fixed in the middle of the outer surface of the movable plate 33. A second spring 35 is fixed on one side of the connecting plate 34. A limiting wheel 36 is installed at one end of the second spring 35 and contacts the outer surface of the end cap.

[0043] The square groove 31 provides a horizontal sliding channel for the movable plate 33. The limiting frame 32 cooperates with the square groove 31 to limit and support the movable plate 33. Under the elastic force of the second spring 35, the movable plate 33 can move towards the center along the square groove 31 and the limiting frame 32, thereby driving the connecting plate 34 and the limiting wheel 36 to move synchronously, thereby clamping the end cap. The limiting wheel 36 can roll flexibly with the slight displacement of the end cap, always maintaining close contact with the end cap, effectively preventing the end cap from shifting during the pressing process, and ensuring the accuracy of the pressing operation.

[0044] Working principle:

[0045] During the pressing process, the second spring 35 drives the connecting plate 34 to move towards the center, causing the movable plate 33 to move towards the center simultaneously, and causing the limiting wheel 36 to move towards the center to clamp the end cap.

[0046] This step can automatically adjust the clamping force according to the size of the end cap, ensuring that the end cap is stably clamped and avoiding damage or deformation to the end cap surface due to rigid clamping. It is especially suitable for end caps of different diameters. At the same time, the elastic force of the second spring 35 is consistently stable, which can always provide reliable power for clamping during the pressing process and prevent the end cap from loosening.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
