Then, the bolt 11 passes through the bearing seat 6 and is threaded to the bearing base 2 to ensure overall stability. The hook 10 at the top of the bearing seat 6 is convenient for installation and hoisting.
[0024] Reference Figures 1 to 6 The sealing mechanism 5 includes a sealing support ring block 501, a sealing ring plate 502, and an outer sealing ring 503. The sealing support ring block 501 is fixedly connected to one end of the outer side of the roll neck 3, and it serves as a basic support and connects other sealing components. The sealing ring plate 502 is fixedly connected to one end of the outer side of the sealing support ring block 501. The sealing ring plate 502 can be embedded into the sealing groove 8 on the inner side of the bearing base 2 and the bearing upper seat 6, so as to achieve a tight fit with the sealing groove 8, thereby sealing the corresponding position and preventing abnormal flow of impurities, lubricating oil, etc. The outer sealing ring 503 is fixedly connected to one end of the front side of the sealing support ring block 501. It can be tightly fitted with the arc-shaped sealing groove 9 on the outer side of the bearing base 2 and the bearing upper seat 6, forming an effective sealing isolation between the external environment and the area around the roll neck 3, preventing external dust, impurities, etc. from entering the interior and affecting the normal operation of the roll and bearing. The sealing support ring block 501, the sealing ring plate 502, and the outer sealing ring 503 are all movably connected to the bearing base 2.
[0025] The elastic sealing sleeve 504 and the elastic locking ring 505 are fixedly connected to the other end of the front of the sealing support ring block 501. The elastic locking ring 505 is sleeved on the outer end of the elastic sealing sleeve 504. The elastic sealing sleeve 504 is sleeved with the roll neck 3. The two ends of the elastic locking ring 505 are firmly fixed by fasteners, thereby firmly fixing the elastic sealing sleeve 504 to the outside of the roll neck 3.
[0026] The sealing support ring block 501 is adapted to the ring frame groove 7, the sealing ring plate 502 is adapted to the sealing groove ring groove 8, the outer sealing ring 503 is adapted to the arc-shaped sealing groove 9, the outer sealing ring 503 is made of fluororubber material, and a sealing slot 12 is opened at the other end of the outer side of the roll neck 3. The sealing slot 12 is adapted to the elastic locking ring plate 505, and multiple sets of sealing slots 12 and elastic locking ring plates 505 are provided.
[0027] The working principle is as follows: During installation, first assemble the roll necks 3 at both ends of the roll 1 with the roll bearings 4. Place the roll bearings 4 into the space formed by the bearing base 2 and the upper bearing seat 6. Then, use bolts 11 to thread through the upper bearing seat 6 and connect it to the bearing base 2 to ensure overall stability. When the roll 1 starts to rotate, the entire sealing mechanism 5 will rotate synchronously due to the rotation of the roll necks 3. During the rotation, the sealing ring 502 maintains a relatively stable position within the sealing groove 8. It relies on its contact with the sealing groove 8 to continuously block possible lubricating oil leakage and impurities from entering, forming the first line of defense. The external sealing ring 503, in the arc-shaped sealing groove 9, also relies on its good elasticity and adaptability to maintain a seal against the external environment, resisting external dust and oxidation. Impurities such as iron filings intrude into the area surrounding the roll bearing 4 and the roll neck 3, forming a second line of defense. The two ends of the elastic locking ring 505 are firmly fixed by fasteners and precisely locked in the sealing groove 12 of the roll neck 3, thereby firmly fixing the elastic sealing sleeve 504 to the outside of the roll neck 3. This prevents gaps from appearing at the contact point between the elastic sealing sleeve 504 and the roll neck 3, which would result in an incomplete seal. Even if there is a certain axial movement or slight vibration in the roll neck 3, they can adaptively adjust to ensure the continuity of the seal and prevent lubricating oil from leaking out from the roll neck 3 end, forming a third line of defense. This ensures that the entire roll system can operate continuously in a relatively stable, clean and well-lubricated state, ensuring the smooth production of bar and wire rod rolling.
