[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Refer to Figure 1 - Figure 4 , an embodiment provided by the present invention: A capping device for a capping machine, including a base 1 and a chuck body 21. Two limit rods III 12 are fixedly connected to the top of the base 1. The top of the limit rod III 12 is fixedly connected to a top seat 15. A cylinder I 14 is fixedly connected to the lower side of the top seat 15. The output end of the cylinder I 14 is fixedly connected to a moving plate 13. A hydraulic component 16 is arranged on the top of the moving plate 13. A plurality of hydraulic rods 17 are fixedly connected to the top of the hydraulic component 16. The output end of the hydraulic rod 17 is fixedly connected to a connecting plate 18. The bottom of the connecting plate 18 is fixedly connected to a mounting plate 19. Two mounting blocks 20 are fixedly connected to the top of the chuck body 21. A clamping seat 3 is fixedly connected to the top of the base 1. A motor 4 is fixedly connected to the inner wall of the clamping seat 3. The output end of the motor 4 is fixedly connected to a worm 5. A frustum 8 is rotatably connected inside the clamping seat 3. A worm gear 6 is fixedly connected to the outside of the frustum 8. A turntable 7 is fixedly connected to the outside of the frustum 8. The worm gear 6 is meshed with the worm 5. A plurality of arc plates 11 are slidably connected inside the clamping seat 3. A slide bar 10 is slidably connected inside the arc plate 11. A connecting rod 9 is arranged between the arc plate 11 and the turntable 7. A fixing component is arranged inside the mounting plate 19, and the fixing component is used for installing and disassembling the chuck body 21.

[0032] Specifically, after starting the driving cylinder 14, the moving plate 13 can be adjusted to an appropriate height according to the size of the item to be capped. At the same time, the stability during the moving process is enhanced by the third limiting rod 12. On this basis, with the operation of the driving motor 4, the rotation of the worm 5 is further driven. This action causes the synchronous rotation of the worm gear 6, the turntable 7, and the frustum 8, and then drives the connecting rod 9 to rotate. Such a linkage effect enables the arc-shaped plate 11 to smoothly slide outside the sliding rod 10, thereby achieving precise clamping of capping items of various sizes and effectively preventing position deviation during the capping process. Subsequently, through the coordinated action of the driving hydraulic component 16 and the hydraulic rod 17, key components such as the connecting plate 18, the mounting plate 19, and the chuck body 21 start to move downward to perform the actual capping work on the capping item. The entire operation process not only reflects high efficiency but also has sufficient flexibility to adapt to capping requirements of different sizes, ensuring the accuracy and reliability of the operation.

[0033] Refer to Figure 3 and Figure 4 , the fixing component includes a push rod 22. The outside of the push rod 22 is slidably connected inside the mounting plate 19. One end of the push rod 22 is fixedly connected to a push plate 23. A connecting rod 25 is slidably connected inside the push rod 22. One end of the connecting rod 25 is fixedly connected to a second limiting rod 27. A spring 24 is sleeved outside the connecting rod 25. Rotating rods 28 are rotatably connected to both ends of the push plate 23. One end of the rotating rod 28 is rotatably connected to a plugging rod 29. A first limiting rod 26 is slidably connected inside the plugging rod 29.

[0034] Specifically, to disassemble the chuck body 21, the operator needs to start the push rod 22. Through its pushing, the push plate 23 moves inward. This action triggers the sliding of the connecting rod 25 inside the push rod 22 and is thus compressed. As the push plate 23 moves, the rotating rods 28 at both ends thereof also rotate, driving the plugging rod 29 to slide outside the first limiting rod 26. Until the plugging rod 29 completely disengages from the internal space of the mounting block 20, the disassembly process is completed. When it is necessary to reinstall the chuck body 21, the operator releases the push rod 22. Under the action of the connecting rod 25, the push plate 23 and the push rod 22 slide outside the connecting rod 25 under the action of an external force, and then the rotating rod 28 rotates again. Under the restriction of the first limiting rod 26, the plugging rod 29 is inserted back into the internal space of the mounting block 20 to complete the installation.

[0035] Refer to Figure 1 - Figure 4, multiple support columns 2 are fixedly connected to the top of the base 1, anti-slip pads are fixedly connected to the tops of the support columns 2, one end of the connecting rod 9 is fixedly connected to the bottom end of the arc-shaped plate 11, the other end of the connecting rod 9 is rotatably connected to the top edge of the turntable 7, both ends of the slide rod 10 are fixedly connected inside the clamping seat 3, one end of the limiting rod 1 26 is fixedly connected to the inner wall of the mounting plate 19, the plugging rod 29 is plugged inside the mounting block 20, one end of the spring 24 is fixedly connected to the limiting rod 2 27, the other end of the spring 24 is fixedly connected to one side of the push plate 23, the outer side of the connecting rod 25 is slidably connected inside the push plate 23, and the bottom of the limiting rod 2 27 is fixedly connected to the inner wall of the mounting plate 19.

[0036] Specifically, multiple support columns 2 are stably connected to the top of the base 1, and anti-slip pads are fixed to the tops of these support columns 2, aiming to provide a stable support foundation and reduce friction. One end of the connecting rod 9 is fixed to the bottom of the arc-shaped plate 11, while the other end is rotatably connected to the edge of the top of the turntable 7, which ensures that the arc-shaped plate 11 can move flexibly following the rotation of the turntable 7. Both ends of the slide rod 10 are respectively fixed inside the clamping seat 3, providing a track for the movement of the arc-shaped plate 11. One end of the limiting rod 1 26 is fixed to the inner wall of the mounting plate 19, used to limit the movement range of the plugging rod 29 to ensure its accurate insertion into or withdrawal from the inside of the mounting block 20. The plugging rod 29 is directly inserted into the mounting block 20 to achieve the fixing and disassembly of the chuck body 21. One end of the spring 24 is fixed to the limiting rod 2 27, while the other end is connected to one side of the push plate 23, giving the push plate 23 a certain elastic restoring force. The connecting rod 25 is slidably connected to the outside inside the push plate 23 to help the push plate 23 achieve smooth forward and backward movement during operation. The bottom of the limiting rod 2 27 is fixed to the inner wall of the mounting plate 19, playing a role in compressing the spring 24.

[0037] Working principle: First, when driving the cylinder 1 14, the moving plate 13 can be adjusted in height according to the size of the capping object, and at the same time, the stability of its movement is increased through the setting of the limiting rod 3 12. At this time, by driving the motor 4, the worm 5 is driven to rotate, causing the worm gear 6, the turntable 7, and the frustum 8 to rotate, and then driving the connecting rod 9 to rotate, so that the arc-shaped plate 11 slides outside the slide rod 10, thereby realizing the clamping of capping objects of different sizes and avoiding deviation during capping. At this time, the hydraulic components 16 and the hydraulic rod 17 can be driven to drive structures such as the connecting plate 18, the mounting plate 19, and the chuck body 21 to move downward to perform the capping work on the capping object.

[0038] When it is necessary to disassemble the chuck body 21, at this time, push the push rod 22, which will drive the push plate 23 to move inward, and then make the connecting rod 25 slide inside the push rod 22. At this time, the connecting rod 25 is compressed, and the rotating rods 28 at both ends of the push plate 23 rotate, which will drive the plugging rod 29 to slide outside the first limiting rod 26 until the plugging rod 29 leaves the inside of the mounting block 20, and at this time, the disassembly is completed. When it is necessary to install, loosen the push rod 22, and then under the action of the connecting rod 25, drive the push plate 23 and the push rod 22 to slide outside the connecting rod 25, which will drive the rotating rod 28 to rotate, so that the plugging rod 29 is re-plugged into the inside of the mounting block 20 under the limitation of the first limiting rod 26, and at this time, the installation is completed. In this way, the corresponding type of chuck body 21 can be quickly replaced according to the type of the capping object, improving the applicability of the device to different capping objects. Each component of the device complements each other.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
