Description

Technical Field

[0001] The utility model relates to the technical field of joints, and particularly relates to a roll rotary joint for aluminum foil rolling. Background Technique

[0002] The aluminum foil roughing mill is a device that rolls aluminum strip coils with a thickness of less than 0.5 mm into aluminum foil with a thickness of more than 2×0.0045 mm through several passes. When the aluminum foil rolling mill is working, the aluminum foil is processed by the hot rolling method of the rolling rolls. During the processing, the rolling rolls need to bear a great pressure. At the same time, due to the very high hot rolling temperature, the rolling rolls need to work continuously under high temperature and high pressure. During the hot rolling process, it is necessary to cool the rolling rolls in time. Otherwise, the rolling rolls will be deformed and scrapped. In order to ensure the normal use of the rolling rolls, in the prior art, cooling water is introduced into the interior of the rolling rolls to cool the rolling rolls. However, during the use of the rolling rolls, they will continuously rotate, and the rotation will cause problems with the seal at the connection between the cooling water pipeline and the rolling rolls and leakage.

It includes an elbow, a housing, a spring, a support pad, a rotor, an inner pipe, a bearing and a dynamic seal ring. The dynamic seal ring includes a seal ring seat, a first sealing ring, a first ear-shaped dynamic ring and a first wire retaining ring. Compared with the prior art, the beneficial effect of the utility model is that: since the dynamic seal ring is used to replace the original glue bonding structure, the problem of seal failure caused by the aging of the sealant due to high temperature is avoided, and the service life of the rotary joint can be extended.

[0004] There are some problems in the above technical solution during use. Since the rolling rolls need to be regularly overhauled during long-term use, the rotary joint in the above technical solution cannot achieve the quick disassembly and assembly of the rolling rolls and the pipeline, which is not conducive to overhaul. Moreover, the sealing structure of the above technical solution is simple, and leakage may still occur in its rotating part during long-term use.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model provides a roll rotary joint for aluminum foil rolling as shown in Figures 1-5 FIG., which includes a water outlet joint 1 and a water inlet joint 2, and a connecting pipe 3 is arranged between the water outlet joint 1 and the water inlet joint 2;

[0024] Specifically, a positioning ring 4 is fixedly arranged at one end of the outer side wall of the connecting pipe 3. A plurality of grooves 5 with hemispherical structures are arranged around the outer side wall of the positioning ring 4. One end of the water inlet joint 2 is fixedly provided with a connecting sleeve 6 with an annular structure. A plurality of chutes 7 with hemispherical structures are arranged around the inner side wall of the connecting sleeve 6. A spherical block 8 is arranged inside the chute 7, and the spherical block 8 corresponds to the groove 5.

[0025] More specifically, an annular groove 9 is arranged in the middle of the outer side wall of the connecting sleeve 6. One end of the chute 7 is communicated with the annular groove 9. A movable ring 10 is arranged inside the annular groove 9. A limiting ring 11 is fixedly arranged in the middle of the inner side wall of the movable ring 10. A spring is arranged between the limiting ring 11 and the inner wall of the annular groove 9. An extension groove 12 is arranged at one end of the inner side wall of the movable ring 10 away from the spring. The arrangement of the extension groove 12 enables the spherical block 8 to slide outwards and separate from the groove 5 to release the limit between the connecting sleeve 6 and the positioning ring 4.

[0026] Moreover, sealing grooves 13 are arranged at the mutually approaching ends of the water inlet joint 2 and the connecting pipe 3. Sealing rings 14 are arranged inside the sealing grooves 13. The sealing rings 14 and the sealing grooves 13 can achieve static sealing between the water inlet joint 2 and the connecting pipe 3.

[0027] Furthermore, an annular connecting groove 15 is arranged at one end of the inner side wall of the connecting pipe 3. A sealing sleeve 16 is arranged outside the connecting groove 15, and the sealing sleeve 16 is fixedly arranged at one end of the water outlet joint 1. The cross-section of the sealing sleeve 16 is arranged in an "L" shape structure, and one end of the sealing sleeve 16 is arranged inside the connecting groove 15. A plurality of spiral mounting grooves 17 are arranged around the outer side wall of the sealing sleeve 16. Spiral sealing blocks 18 are arranged inside the mounting grooves 17, and the outer side wall of the sealing blocks 18 is attached to the inner wall of the connecting groove 15. Since the sealing blocks 18 are arranged in a spiral structure, the sealing blocks 18 are pressed against the inner wall of the connecting groove 15 during rotation to achieve the effect of dynamic sealing.

[0028] At the same time, annular ball grooves 19 are arranged at the mutually approaching ends of the water outlet joint 1 and the connecting pipe 3, and a plurality of balls 20 are arranged inside the ball grooves 19. The arrangement of the balls 20 ensures the smooth rotation between the water outlet joint 1 and the connecting pipe 3.

[0029] The working principle of the present utility model:

[0030] When the device is in use, the water outlet joint 1 is installed at the connection of the roller, and the water inlet joint 2 is connected to the pipeline of the cooling water. When connecting the water outlet joint 1 and the water inlet joint 2, by pulling the movable ring 10, the extension groove 12 inside the movable ring 10 is aligned with the spherical block 8. Then, the connecting sleeve 6 is sleeved outside the positioning ring 4 at one end of the connecting pipe 3. At this time, the spherical block 8 is squeezed by the positioning ring 4 and slides into the extension groove 12. When the connecting sleeve 6 is completely sleeved outside the positioning ring 4, release the movable ring 10, and the movable ring 10 resets under the action of the limiting ring 11 and the spring. At this time, the spherical block 8 enters the groove 5 under the extrusion of the movable ring 10. The cooperation between the spherical block 8 and the groove 5 fixes the position between the connecting sleeve 6 and the positioning ring 4. At this time, the connection between the connecting pipe 3 and the water inlet joint 2 can be realized, and the cooling water can enter the roller through the water inlet joint 2, the connecting pipe 3 and the water outlet joint 1.

[0031] When the roller drives the water outlet joint 1 to rotate, the water outlet joint 1 drives the sealing sleeve 16 to rotate, so that the sealing sleeve 16 rotates in the connection groove 15. During the rotation of the sealing sleeve 16, the sealing block 18 is driven to rotate. Since the sealing block 18 is arranged in a spiral structure, the sealing block 18 is pressed against the inner wall of the connection groove 15 during rotation to achieve the effect of dynamic sealing, thereby ensuring the sealing effect between the sealing sleeve 16 and the connection groove 15.

[0032] 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 recorded 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 in the protection scope of the present invention.
