[0002] When the traction cooling steel rollers of a Brückner BOPP production line operate at high speed, the guide siphon tubes within the rollers move relative to each other. This relative motion causes wear on the roller's stationary rings. As fluid passes through, it takes a shortcut back, preventing effective cooling of the roller and severely impacting product quality. The rollers measure 8.6 meters by 0.458 meters, and due to the 988mm deep stop of the roller's stationary ring, they cannot be repaired online. The roller's complex flow path makes repairing the stop difficult and expensive, failing to meet the high-quality production demands of film manufacturers. Summary of the Invention

[0025] A device for realizing split-type protection of a static ring stop by a rotating siphon pipe, comprising: a first siphon pipe 1 and a second siphon pipe 2;

[0026] The first siphon tube 1 is linearly and evenly distributed with grooves 3; each groove 3 is fixedly installed with a sealing ring 4; the side of the first siphon tube 1 where the sealing ring 4 is installed is arranged inside the second siphon tube 2; the sealing ring 4 is against the inner wall of the first siphon tube 1; the side of the second siphon tube 2 close to the sealing ring 4 is fixedly installed with a connecting block 5.

[0027] During use, the second siphon tube 2 is inserted into the inner stop 10 of the roller 11, and the connecting block 5 on the second siphon tube 2 is fixed to the end surface and inner wall of the roller 11; then the sealing ring 4 is first installed in the groove 3 of the first siphon tube 1, and then the side with the sealing ring 4 is inserted into the end of the second siphon tube 2 with the connecting block 5. The other end of the first siphon tube 1 is connected to the rotary joint, and the rotary joint is connected to the external pipeline; the cooling medium is transmitted into the interior of the roller 11 through the pipeline, the rotary joint, the first siphon tube 1 and the second siphon tube 2, thereby circulating and cooling; the sealing ring 4 plays a sealing role to prevent the cooling medium from flowing out from the gap between the first siphon tube 1 and the second siphon tube 2;

[0028] Since the roller 11 is too long, even if the roller 11 is slightly offset, the siphon tube connected to the inner stop 10 of the roller 11 will be misaligned at the stop 10, resulting in a break; at the same time, after the second siphon tube 2 and the first siphon tube 1 are installed as mentioned above, the second siphon tube 2 rotates with the roller 11, thereby rotating relative to the first siphon tube 1, that is, the rotation connection point of the second siphon tube 2 and the first siphon tube 1 is at the sealing ring 4; when the second siphon tube 2 rotates with the roller 11, if the roller 11 rotates eccentrically, the second siphon tube 2 will squeeze the sealing ring 4, and the sealing ring 4 has a certain elasticity and can shrink, reducing the probability of wear between the second siphon tube 2 and the first siphon tube 1; if the eccentricity is large and the sealing ring 4 is worn flat, the other end of the first siphon tube 1 can be removed, so that the second siphon tube 2 is pulled out and the first siphon tube 1 is replaced. A sealing ring 4 on a siphon tube 1; if the eccentricity is further increased, since the second siphon tube 2 is protected by the connecting block 5, the part of the first siphon tube 1 located in the second siphon tube 2 has no other support points, so the first siphon tube 1 is easily broken. At this time, the other end of the first siphon tube 1 can be connected and removed, so as to be pulled out of the second siphon tube 2 and the first siphon tube 1 can be replaced; therefore, the problem of damage to the connecting pipe of the static ring stop 10 of the roller 11 due to the eccentricity of the roller 11 is converted into a problem of wear of the first siphon tube 1 at the second siphon tube 2; since the depth of the static ring stop 10 of the roller 11 is 988 mm, it is not convenient to enter for maintenance, and the size of the roller 11 is 8.6 meters X 0.458 meters, which is difficult to disassemble; adopting the above structure, the above problem can be solved by replacing the first siphon tube 1 and the sealing ring 4, which is convenient for maintenance and simple to disassemble.

[0029] In this application, the sealing ring 4 refers to a rubber component used to prevent the leakage of liquids or gases. In hydraulic systems, pneumatic systems, automobile engines, industrial pipelines, and other equipment, the presence of operating pressure can lead to medium leakage without the sealing effect of the sealing ring, seriously affecting the normal operation and efficiency of the equipment. The sealing ring should have good sealing performance within the operating pressure and a certain temperature range, and the sealing performance should automatically improve with increasing pressure. The friction between the sealing ring device and the moving parts should be low, and the friction coefficient should be stable. The sealing ring has strong corrosion resistance, is not easy to age, has a long service life, is wear-resistant, and can automatically compensate for wear to a certain extent. It has a simple structure and is easy to use and maintain, which makes the sealing ring have a longer life. Common types include NBR nitrile rubber sealing rings, HNBR hydrogenated nitrile rubber sealing rings, SIL silicone rubber sealing rings, VITON fluororubber sealing rings, FLS fluorosilicone rubber sealing rings, EPDM ethylene propylene diene monomer rubber sealing rings, IIR butyl rubber sealing rings, etc.

[0030] In some embodiments, the first siphon tube 1 is composed of a first section of tube 6 and a second section of tube 7; the groove 3 is set on the first section of tube 6; the outer diameter of the second section of tube 7 is larger than the inner diameter of the second siphon tube 2; the first section of tube 6 needs to be inserted into the second siphon tube 2, and the outer diameter of the second section of tube 7 is larger than the inner diameter of the second siphon tube 2, and the second section of tube 7 cannot be inserted into the second siphon tube 2. A shoulder is formed at the connection between the second section of tube 7 and the first section of tube 6, and the shoulder is used to fit with the end face of the second siphon tube 2. After fitting, the first section of tube 6 is located inside the second siphon tube 2, thereby providing an auxiliary positioning for the position of the first siphon tube 1 inserted into the second siphon tube 2.

[0031] In some embodiments, a rib 8 is fixedly installed on the side of the second section of the tube 7 away from the first section of the tube 6; a rib 8 is also fixedly installed on the side of the second siphon tube 2 away from the connecting strip; the function of the rib 8 on the second section of the tube 7 is to be used for fixed connection and assistance with the connecting piece; the rib 8 of the second siphon tube 2 is used to assist in positioning, and when the rib 8 is against the stationary ring stop 10 of the roller 11, part of the second siphon tube 2 enters the stationary ring stop 10 of the roller 11, and then fixes the connecting block 5 to the end face and inner wall of the roller 11; the above-mentioned fixing methods include but are not limited to welding, screw connection, spline connection, and wedge pin connection.

[0032] In some embodiments, the cross-section of the rib 8 is annular, a convex polygon with a circular hole, or a concave polygon with a circular hole; the outer dimensions of the rib 8 are not limited and can be selected according to needs, preferably annular, and the annular rib 8 can be processed integrally with the siphon tube.

[0033] In some embodiments, the connecting block 5 is in the shape of a ring or a rectangle.

[0034] In some embodiments, the connecting block 5 is rectangular; the second siphon tube 2 is fixedly installed with at least four connecting blocks 5 in a circular manner; the use of four rectangular connecting blocks 5 makes it easy to adjust the direction when the second siphon tube 2 is fixed together with the inside of the roller 11, so that the axis of the second siphon tube 2 is aligned with the axis of the roller 11.

[0035] In some embodiments, the first siphon tube 1 is provided with at least four grooves 3; since the first siphon tube 1 and the second siphon tube 2 may rotate eccentrically, four grooves 3 are provided at the same time, that is, four sealing rings 4 are installed. Even if eccentric rotation occurs, the leakage of the medium can be avoided due to the layered sealing effect of the four sealing rings 4.

[0036] In some embodiments, the distance between the connecting block 5 and the end surface of the second siphon tube 2 is 0-5 mm.

[0037] The following is a further description of a device for realizing split-type protection of the static ring stop of a rotating siphon provided by the present invention in conjunction with the accompanying drawings and implementation methods.

[0038] A device for realizing split-type protection of a static ring stop by a rotating siphon pipe, comprising: a first siphon pipe 1 and a second siphon pipe 2;

[0039] The first siphon tube 1 consists of a first section of tube 6 and a second section of tube 7; the outer diameter of the second section of tube 7 is larger than the inner diameter of the second siphon tube 2; the first section of tube 6 is linearly and evenly distributed with 4 grooves 3; the grooves 3 are fixedly installed with sealing rings 4; the first section of tube 6 is arranged inside the second siphon tube 2; the sealing ring 4 is against the inner wall of the first siphon tube 1; at least four rectangular connecting blocks 5 are fixedly installed in a circular manner on the side of the second siphon tube 2 close to the sealing ring 4; the side of the second section of tube 7 away from the first section of tube 6 is fixedly installed with a rib 8; the side of the second siphon tube 2 away from the connecting strip is also fixedly installed with a rib 8; the ribs 8 are all annular.

[0040] When in use, insert the second siphon tube 2 into the inner stop 10 of the roller 11 until the rib 8 abuts against the stop 10 of the stationary ring of the roller 11, then weld the connecting block 5 on the second siphon tube 2 to the end face and inner wall of the roller 11; and keep the second siphon tube 2 aligned with the axial direction of the roller 11.

[0041] Next, install the sealing ring 4 in the groove 3 of the first siphon tube 1. Then, insert the side with the sealing ring 4 into the end of the second siphon tube 2 equipped with the connecting block 5. The other end of the first siphon tube 1 is inserted into the rotary joint and fixed to the rotary joint by the retaining edge 8. The rotary joint is connected to the external pipeline. The cooling medium is transferred into the interior of the roller 11 through the pipeline, the rotary joint, the first siphon tube 1 and the second siphon tube 2, thereby circulating the temperature.

[0042] When the second siphon tube 2 rotates following the roller 11, if the roller 11 rotates eccentrically, the second siphon tube 2 will squeeze the sealing ring 4, which has a certain elasticity and can shrink, thereby reducing the probability of wear between the second siphon tube 2 and the first siphon tube 1;

[0043] If the eccentricity is large and the sealing ring 4 is worn flat, the other end of the first siphon tube 1 can be disconnected and removed, thereby extracting the second siphon tube 2 and replacing the sealing ring 4 on the first siphon tube 1;

[0044] If the eccentricity is further increased, since the second siphon tube 2 is protected by the connecting block 5, the part of the first siphon tube 1 located inside the second siphon tube 2 has no other support points, so the first siphon tube 1 is easily broken. At this time, the other end of the first siphon tube 1 can be removed and pulled out of the second siphon tube 2, and the first siphon tube 1 can be replaced.

[0045] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and modifications fall within the scope of the invention as claimed.
