Technical Field

[0001] The utility model relates to the technical field of rotary joints, in particular to a double-channel rotary joint for roller body processing. Background Art

[0002] A rotary joint is a device that allows two connected parts to rotate relative to each other in one or more axial directions. In equipment that requires the roller to be heated or cooled, a double-passage rotary joint is often used. The joint rotor and the stator wall wire form a passage, and the elbow and the inner tube form a passage to realize the circulation of the medium in the roller body to achieve a heating or cooling effect.

[0003] In some prior art double-channel rotary joints for roller body processing, the length of some roller bodies is very long, which requires a longer inner tube to achieve circulation. However, in the original rotary joint structure, the inner tube is directly locked on the stator of the rotary joint. The excessively long inner tube causes the stator to bear a larger inner tube weight, and the inner tube vibrates more during operation, which seriously affects the life and stability of the mechanical seal. Therefore, in view of the above shortcomings, a double-channel rotary joint for roller body processing is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a double-channel rotary joint for roller body processing, aiming to improve the existing technical part, in which the inner tube is directly locked on the stator of the rotary joint in the original rotary joint structure, the excessively long inner tube causes the stator to bear a larger inner tube weight, and the inner tube vibrates more during operation, which seriously affects the life and stability of the mechanical seal.

[0006] Furthermore, a plurality of springs are arranged inside the top end of the stator tee, and a stop pin is fixedly connected inside the bottom end of the stator tee.

[0007] Furthermore, the internal thread of the lock nut is connected to the inside of the outer section of the inner tube, and a hole card is fixedly connected to one side of the right side bearing.

[0008] Furthermore, the outer sleeve of the spacer is provided with a shaft clamp, and the top end of the bearing chamber is fixedly connected to an oil nozzle.

[0009] Furthermore, the far sides of the two static sealing rings are respectively in contact with one side of the plurality of static ring auxiliary O-rings, and one side of the plurality of inner tube auxiliary O-rings is in contact with the inside of the stator tee.

[0010] Further, one side of the static sealing ring contacts one side of the dynamic sealing ring, and the far sides of the two dynamic sealing rings contact the near sides of the two dynamic ring auxiliary O-rings.

[0011] The utility model has the following beneficial effects:

[0012] In the utility model, through the mutual cooperation of structures such as the outer segment of the inner tube, the inner segment of the inner tube, the lock nut, the rotor connecting piece, the dynamic sealing ring, the static sealing ring, the static ring auxiliary O-ring, the dynamic ring auxiliary O-ring, and the inner tube auxiliary O-ring, the inner tube can be divided into two sections and connected through the threads of the rotor. The inner tube of the inner segment will be secondary processed as a whole with the shaft to ensure the stability of the inner tube. Since the rotor of the outer segment of the inner tube is directly fastened to the roller body through the connecting piece, no matter how much the weight of the inner tube is or how much vibration there is, it will not affect the mechanical seal.
