Description

High-stability sealing roller for metal rolling Technical Field The utility model particularly relates to the technical field of sealing rollers, in particular to a high-stability sealing roller for metal rolling. Background With the rapid development of modern industry, the demands for metal products are increasing, and the demands for quality, precision and the like of the metal products are also increasing. Metal rolling is an important process for producing products such as metal plates, pipes, profiles and the like, and plays a vital role in the industries such as steel, nonferrous metals and the like. In order to improve the production efficiency and reduce the cost, the metal rolling industry is continuously developed to the directions of high speed, large size and automation, and thus, higher requirements are put on a key component of rolling equipment, namely a roller, particularly in the aspects of sealing performance and stability. In the metal rolling process, the rolls are required to operate in a high-speed rotation, high temperature, high pressure and severe working environment. Traditional roller sealing modes, such as packing sealing, lip sealing and the like, are difficult to maintain good sealing performance for a long time under such complex working conditions, and are easy to cause sealing failure, so that lubricating oil leakage and external impurities enter the roller to influence the normal operation and service life of the roller. The sealing structure of the traditional roller has insufficient stability when facing the conditions of vibration, impact and the like in the rolling process, and is easy to cause the problems of abrasion, deformation and the like of sealing parts. This not only results in a decrease in sealing performance, but also makes the running state of the roll unstable, thereby affecting the accuracy of metal rolling and the quality of products, such as uneven thickness of the sheet material, surface quality defects, and the like. Disclosure of utility model The utility model aims to provide a high-stability sealing roller for metal rolling, which remarkably improves the sealing performance of the sealing roller by installing a roller shaft and a roller, so as to solve the technical problems in the prior art. In order to achieve the above purpose, the present utility model provides the following technical solutions: a high-stability sealing roller for rolling metal comprises The roller shaft is provided with a roller; The roll shaft comprises a central shaft, roll necks are symmetrically arranged at two ends of the central shaft, a first sealing ring is connected to the roll necks, sealing sheets are arranged in a fixing groove at the bottom of the first sealing ring, a sealing sleeve is arranged at the upper end of the first sealing ring, and a second sealing ring is arranged at the inner side of the sealing sleeve. As a further technical scheme of the utility model, the upper end of the sealing sleeve is provided with a connecting ring, a plurality of springs are arranged on the connecting ring, and the upper ends of the springs are connected with the top ring. As a further technical scheme of the utility model, the top ring is connected with the connecting ring through a plurality of clamping nuts, the side surface of the top ring is also provided with a plurality of limit nuts, the roll neck is connected and fixed through the plurality of limit nuts, and the end part of the roll neck is provided with a fixing nut. As a further technical scheme of the utility model, the bottoms of the first sealing ring and the sealing piece are rotatably connected with a static ring, and the static ring is fixed with the central shaft through a fixing bolt. As a further technical scheme of the utility model, the static ring is arranged at one end of the baffle, the baffle is arranged at two ends of the outer cylinder and is in sealing connection, the inner side of the outer cylinder is symmetrically provided with the inner sealing ring, the inner sealing ring is positioned at the other end of the baffle, the other end of the inner sealing ring is provided with the inner connecting ring, the inner connecting ring is also connected with the inner side of the outer cylinder, and the baffle, the inner sealing ring and the inner connecting ring are all connected with the central shaft. Compared with the prior art, the utility model has the beneficial effects that: When the roller is used, the roller necks at two ends are firstly arranged on the installation station, the connecting rings and the top rings are arranged on the roller necks, the springs are arranged between the connecting rings and the top rings, when the sealing surfaces of the connecting rings and the top rings are changed due to abrasion, shaft movement, thermal expansion and other reasons, the springs automatically stretch and contract according to the stress condition to push the top rings to move along the roller
