[0023] The specific configuration and function of this embodiment are described in detail below. During the steel rolling process, the steel enters from one side of the guide, passes between the two groups of rollers 3, and moves out from the other end of the guide. During the movement of the steel, the steel drives the two groups of rollers 3 to rotate, and the surfaces of the two groups of rollers 3 will be attached with oxide scale on the surface of the steel. During the rotation of the rollers 3, when the oxide scale rotates to one side of the sponge roller 42, the sponge roller 42 is tightly attached to one side of the roller 3, and the surface of the sponge roller 42 has many protruding particles, which will adhere to the surface of the roller 3. The oxide scale on the sponge roller 42 is scraped off, and a collection box is placed on the top of the base 1 below the sponge roller 42 to collect the oxide scale and impurities. When one side of the sponge roller 42 has been used for a long time, many small impurities and lubricating oil will adhere to the surface. At this time, the positioning rod 46 and the connecting rod 45 are folded outward to make it horizontal, and then the fixing rod 43 is rotated to make the limiting ear 44 drive the sponge roller 42 to rotate, so that the clean side of the sponge roller 42 is in contact with the side wall of the roller 3, and then the connecting rod 45 and the positioning rod 46 are folded upward to make it horizontal. The locking rod 46 is locked in the inside of the fixing plate 41, so that the sponge roller 42 can continue to be used. When the sponge roller 42 needs to be removed and replaced, the connecting rod 45 and the locking rod 46 are folded to make them horizontal, and then the fixing rod 43 and the limiting ear 44 are rotated 90° so that the direction angle of the limiting ear 44 fits the groove inside the fixing plate 41, and then the fixing rod 43 can be directly pulled out horizontally, and the sponge roller 42 is between the two sets of fixing plates 41. Then the sponge roller 42 is replaced for installation. By setting the cleaning mechanism 4, self-cleaning is achieved during the rotation of the roller 3. The sponge roller 42 can clean the roller 3 to keep its surface clean, reduce stain accumulation, reduce friction resistance, improve the operation efficiency of the steel rolling production line, avoid the oxide scale attached to the surface of the roller 3 to contaminate the product, ensure that the surface of the rolled steel is smooth and flawless, improve product quality, reduce the wear between the roller 3 and the steel, extend the service life of the guide roller 3, reduce equipment maintenance costs, reduce friction resistance, reduce energy consumption, meet environmental protection requirements, and improve production efficiency.

[0024] Embodiment 2: Figure 2 and Figure 4 As shown, a fixing bolt 5 is provided inside the roller 3, the top of the fixing bolt 5 passes through the interior of the moving seat 2, the bottom of the fixing bolt 5 is connected to the internal thread of the moving seat 2, the bottoms of the two groups of moving seats 2 are fixedly installed with threaded seats 6, the two groups of threaded seats 6 are provided with bidirectional screws 7, the outer walls of the bidirectional screws 7 are threadedly connected to the inner walls of the two groups of threaded seats 6, and a hand handle 8 is fixedly installed on one side of the bidirectional screw 7.

[0025] The effect achieved by the entire embodiment is that the hand grip 8 is rotated to make the bidirectional screw 7 drive the two sets of threaded seats 6 and the movable seat 2 to move, thereby adjusting the distance between the two sets of rollers 3 to make it suitable for steel of different coarseness and fineness. When the roller 3 is worn out after a long period of use and needs to be replaced, the fixing bolt 5 is rotated to make the fixing bolt 5 gradually disengage from the movable seat 2, and then the fixing bolt 5 is pulled out upward, so that the roller 3 is separated from the movable seat 2. When the fixing rod 43 and the sponge roller 42 are not installed, the roller 3 can be pulled out from one side of the movable seat 2 to replace and install the roller 3. By setting the fixing bolt 5, the position of the roller 3 during installation can be ensured to be accurate and stable, the installation process can be simplified, and the installation time and labor cost can be reduced. The fixing bolt 5 can fix the position of the roller 3 to prevent the position from moving or loosening during use, improve the installation accuracy, ensure the stability and accuracy of the steel rolling process, and effectively prevent the roller 3 from falling off or shifting during operation, reduce the risk of accidents, and improve work safety.

[0026] The method of using and the working principle of the device are as follows: the hand grip 8 is rotated to make the bidirectional screw 7 drive the two sets of threaded seats 6 and the movable seat 2 to move, so as to adjust the distance between the two sets of rollers 3 to make it suitable for steels of different thicknesses. When the roller 3 is worn out after a long period of use and needs to be replaced, the fixing bolt 5 is rotated to make the fixing bolt 5 gradually disengage from the movable seat 2, and then the fixing bolt 5 is pulled out upward, so that the roller 3 is disengaged from the movable seat 2. When the fixing rod 43 and the sponge roller 42 are not installed, the roller 3 can be pulled out from one side of the movable seat 2 to replace and install the roller 3.

During the rotation of the roller 3, when the oxide scale rotates to one side of the sponge roller 42, the sponge roller 42 is tightly attached to one side of the roller 3, and there are many raised particles on the surface of the sponge roller 42, which will cause the roller 3 to move. 3. Scrape off the oxide scale attached to the surface. Place a collection box on the top of the base 1 below the sponge roller 42 to collect the oxide scale and impurities. When one side of the sponge roller 42 is used for a long time, many small impurities and lubricating oil will be attached to the surface. At this time, fold the positioning rod 46 and the connecting rod 45 outward to make them horizontal, and then rotate the fixing rod 43 so that the limiting ear 44 drives the sponge roller 42 to rotate, so that the clean side of the sponge roller 42 is in contact with the side wall of the roller 3, and then fold the connecting rod 45 upward. And the locking rod 46, so that the locking rod 46 is stuck in the inside of the fixed plate 41, so that the sponge roller 42 can continue to be used.
