Description

Technical Field

[0001] This application belongs to the technical field of bottle cap installation equipment, specifically an improved rotary joint. Background Technology

[0002] In the bottle cap manufacturing and assembly industry, rotary joints are the core components connecting bottle caps and bottles, and their performance directly affects production efficiency and product quality. With the development of the packaging industry, bottle cap specifications and materials are becoming increasingly diverse, from plastic caps to metal caps, and from standard sizes to custom shapes, placing higher demands on the adaptability of installation equipment.

[0003] Currently, rotary joints are a key component of automated production lines, and their operational stability and adaptability have become important considerations for enterprises to improve production capacity. High-efficiency rotary joints enable rapid and accurate installation of bottle caps, while low-efficiency ones can lead to production stoppages and product defects.

[0004] However, most existing rotary joints are designed for specific bottle cap sizes and have poor versatility. When different bottle cap sizes need to be installed, the rotary joints need to be changed frequently, which not only increases production costs but also reduces production efficiency. Utility Model Content

[0005] The purpose of this application is to provide an improved rotary joint, which addresses the problem that most existing rotary joints are designed for specific bottle cap sizes and have poor versatility. When different bottle cap sizes need to be installed, the rotary joints need to be changed frequently, which not only increases production costs but also reduces production efficiency.

[0006] The technical solution adopted in this application is as follows: An improved rotary joint includes a mounting base, a turntable rotatably connected to the lower end of the mounting base, connecting columns mounted on both sides of the lower surface of the mounting base, a rotating shaft rotatably connected to one end of each connecting column, a rotary joint mounting block mounted on one side of the rotating shaft, a plurality of connecting plates mounted on the outer surface of the rotary joint mounting block, and a rotary joint mounted on one side of each connecting plate, wherein the dimensions of the rotary joints are different.

[0007] By adopting the above technical solution, the rotary joint mounting block is driven to rotate under the action of the rotating shaft, so that the rotary joint mounting block can select a rotary joint of the corresponding size, eliminating the need to spend time changing it, improving work efficiency, reducing production costs, and making the rotary joint easy to replace to meet production needs and improve applicability.

[0008] In a preferred embodiment, a slot is provided on the outer surface of the rotary joint mounting block, a plug is inserted into the slot, and a connecting plate is provided on one side of the plug.

[0009] By adopting the above technical solution, the insert block is inserted into the slot, which facilitates the assembly and disassembly of the rotary joint and improves convenience.

[0010] In a preferred embodiment, a return spring is installed inside the rotary joint mounting block. A connecting plate is provided at one end of the return spring. Fixed posts are provided on both sides of the lower surface of the connecting plate. Fixed slots corresponding to the fixed posts are opened at both ends of one side surface of the mounting block. A connecting rod is provided at one end of the connecting plate. The connecting rod is located inside the return spring. A magnetic plate is provided at one end of the connecting rod. An electromagnetic block corresponding to the magnetic plate is installed inside the rotary joint mounting block.

[0011] By adopting the above technical solution, under the magnetic attraction of the first electromagnetic block, the first magnetic plate is attracted, causing the fixed plug to detach from the inside of the fixed slot, releasing its limiting fixation on the plug, making it convenient for the plug to be inserted and replaced. After the plug is installed, the magnetic attraction of the first electromagnetic block is released, and under the elastic force of the first reset spring, the fixed plug is pushed into the inside of the fixed slot to fix the plug and improve stability.

[0012] In a preferred embodiment, the two ends of the connecting plate 2 are slidably connected to limit slide rods, and the two ends of the limit slide rods are disposed inside the rotary joint mounting block.

[0013] By adopting the above technical solution, the movement of the connecting plate 2 is limited under the action of the limiting slide bar, making its operation more stable and improving the stability of the device.

[0014] In a preferred embodiment, a second return spring is installed inside the connecting column, a third connecting plate is provided at one end of the second return spring, a limit block is provided on one side of the third connecting plate, a plurality of limit slots corresponding to the limit block are opened on the surface of the rotary joint mounting block, a second connecting rod is provided at one end of the third connecting plate, the second connecting rod is located inside the second return spring, a second magnetic plate is provided at one end of the second connecting rod, and an electromagnetic block second corresponding to the second magnetic plate is installed inside the connecting column.

[0015] By adopting the above technical solution, under the magnetic attraction of the second electromagnetic block, the second magnetic plate is attracted, causing the limiting plug to disengage from the inside of the limiting slot, releasing its limiting fixation on the rotary joint mounting block, facilitating the rotation of the rotary joint mounting block. When the rotary joint mounting block rotates to the appropriate position, the magnetic attraction of the second electromagnetic block is released, and under the elastic force of the second return spring, the limiting plug is pushed into the inside of the limiting slot, fixing the rotary joint mounting block and improving stability.

[0016] In a preferred embodiment, a magnetic block one is installed inside the limiting slot, and a magnetic block two corresponding to the magnetic block one is installed at one end of the limiting block.

[0017] By adopting the above technical solution, the magnetic attraction between magnetic block one and magnetic block two improves the stability of the limiting plug inserted into the limiting slot, making it less prone to shaking, and also makes it easier to disconnect the two, thus improving convenience.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0019] In this application, the rotating shaft drives the rotary joint mounting block to rotate, allowing the rotary joint mounting block to select a rotary joint of the corresponding size, eliminating the need for time-consuming replacements, improving work efficiency, reducing production costs, and making the rotary joint easy to replace to meet production needs and improve applicability.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Reference Figure 1-4 An improved rotary joint includes a mounting base 1, a turntable 2 rotatably connected to the lower end of the mounting base 1, connecting posts 3 mounted on both sides of the lower surface of the mounting base 1, a rotating shaft 4 rotatably connected to one end of the connecting posts 3, a rotary joint mounting block 5 mounted on one side of the rotating shaft 4, several connecting plates 7 mounted on the outer surface of the rotary joint mounting block 5, and a rotary joint 6 mounted on one side of the connecting plates 7. The rotary joints 6 are of different sizes. Under the action of the rotating shaft 4, the rotary joint mounting block 5 is driven to rotate, so that the rotary joint mounting block 5 can select a rotary joint 6 of the corresponding size without spending time changing it, improving work efficiency, reducing production costs, and making the rotary joint 6 easy to replace to meet production needs and improve applicability.

[0027] Reference Figure 1-2 The outer surface of the rotary joint mounting block 5 is provided with a slot 9, and a plug 8 is inserted into the slot 9. A connecting plate 7 is provided on one side of the plug 8. Under the action of the plug 8, it is inserted into the slot 9, which can facilitate the disassembly and assembly of the rotary joint 6 and improve convenience.

[0028] Reference Figure 2 The rotary joint mounting block 5 has a return spring 16 installed inside. One end of the return spring 16 is provided with a connecting plate 13. The lower surface of the connecting plate 13 has fixed posts 14 on both sides. One side surface of the plug block 8 has fixed slots 12 corresponding to the fixed posts 14 at both ends. One end of the connecting plate 13 is provided with a connecting rod 11, which is located inside the return spring 16. One end of the connecting rod 11 is provided with a magnetic plate 17. The rotary joint mounting block 5 has an electromagnetic block 18 corresponding to the magnetic plate 17 installed inside. Under the magnetic attraction of the electromagnetic block 18, the magnetic plate 17 is attracted, causing the fixed posts 14 to disengage from the fixed slots 12 and releasing the limiting fixation of the plug block 8, making it convenient for the plug block 8 to be inserted and replaced. After the plug block 8 is installed, the magnetic attraction of the electromagnetic block 18 is released, and under the elastic force of the return spring 16, the fixed posts 14 are pushed into the fixed slots 12 to fix the plug block 8 and improve stability.

[0029] Reference Figure 2The two ends of the connecting plate 2 13 are internally connected to the limiting slide rods 15. The two ends of the limiting slide rods 15 are set inside the rotary joint mounting block 5. Under the action of the limiting slide rods 15, the movement of the connecting plate 2 13 is limited, making its operation more stable and improving the stability of the device.

[0030] Reference Figure 3 A second return spring 21 is installed inside the connecting post 3. A third connecting plate 20 is provided at one end of the second return spring 21. A limit plug 19 is provided on one side of the third connecting plate 20. Several limit slots 10 corresponding to the limit plugs 19 are opened on the surface of the rotary joint mounting block 5. A second connecting rod 22 is provided at one end of the third connecting plate 20. The second connecting rod 22 is located inside the second return spring 21. A second magnetic plate 23 is provided at one end of the second connecting rod 22. A corresponding magnetic plate 23 is installed inside the connecting post 3. Electromagnetic block 24, under the magnetic attraction of electromagnetic block 24, attracts magnetic plate 23, causing limit plug 19 to disengage from the inside of limit slot 10, releasing its limiting fixation on rotary joint mounting block 5, facilitating the rotation of rotary joint mounting block 5. When rotary joint mounting block 5 rotates to the appropriate position, the magnetic attraction of electromagnetic block 24 is released, and under the elastic force of reset spring 21, limit plug 19 is pushed into the inside of limit slot 10, fixing rotary joint mounting block 5 and improving stability.

[0031] Reference Figure 4 The limiting slot 10 is equipped with a magnetic block 25, and one end of the limiting plug 19 is equipped with a magnetic block 26 corresponding to the magnetic block 25. Under the magnetic attraction between the magnetic block 25 and the magnetic block 26, the stability of the limiting plug 19 inserted into the limiting slot 10 is improved, making it less prone to shaking. At the same time, it is also convenient to disconnect the two, improving convenience.

[0032] The implementation principle of an improved rotary joint embodiment of this application is as follows:

[0033] During bottle cap installation, the rotating shaft 4 drives the rotary joint mounting block 5 to rotate, allowing it to select the corresponding size rotary joint 6 for operation. As the rotary joint mounting block 5 rotates, the magnetic attraction of the electromagnetic block 24 attracts the magnetic suction plate 23, causing the limiting insert 19 to disengage from the limiting slot 10, releasing its limiting fixation on the rotary joint mounting block 5 and facilitating its rotation. When the rotary joint mounting block 5 rotates to the appropriate position, the magnetic attraction of the electromagnetic block 24 is released, and the limiting plate 19 is pushed back by the elastic force of the return spring 21. Insert 19 is inserted into the limiting slot 10 to fix the rotary joint mounting block 5 and improve stability. When the rotary joint 6 needs to be replaced, the magnetic attraction of the electromagnetic block 18 attracts the magnetic plate 17, causing the fixed insert 14 to disengage from the fixed slot 12 and release its limiting fixation on the insert 8, making it easier to insert and replace the insert 8. After the insert 8 is installed, the magnetic attraction of the electromagnetic block 18 is released, and the fixed insert 14 is pushed into the fixed slot 12 by the elastic force of the return spring 16 to fix the insert 8 and improve stability.
