[0025] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0026] Please see Figure 1-5 This utility model provides a technical solution:
[0027] A shock-absorbing stabilizing roller includes a stabilizing roller body 1 and a frame assembly 2. A sliding assembly 3 is rotatably connected to the outer side of the stabilizing roller body 1, and the frame assembly 2 is slidably connected to the outer side of the sliding assembly 3. A displacement monitoring assembly 4 is fixedly connected to the inner side of the sliding assembly 3. The frame assembly 2 includes a bracket 21, a guide groove 22 on the inner side of the bracket 21, a hydraulic rod 23 fixedly connected to the inner side of the bracket 21, a fixing plate 24 fixedly connected to one side of the hydraulic rod 23, and a damper 25 fixedly connected to one side of the fixing plate 24. The sliding assembly 3... The system includes an inner hole block 31, with a shaft rotation hole 32 on the inner side of the inner hole block 31. A connecting square plate 33 is fixedly connected to both the front and rear ends of the inner hole block 31. The displacement monitoring component 4 includes a cylindrical shell 41, with a cylindrical slide 42 on the inner side of the cylindrical shell 41. A pressure sensor 43 is fixedly connected to the inner side of the cylindrical slide 42 on the cylindrical shell 41. The inner side of the cylindrical slide 42 on the cylindrical shell 41 is in contact with the outer side of the first magnetic block column 44. A rubber column 45 is fixedly connected to one side of the first magnetic block column 44. A second magnetic block column 46 is fixedly connected to the inner side of the cylindrical slide 42 on the cylindrical shell 41.
[0028] As a further implementation of this scheme, the number of frame assembly 2 and sliding assembly 3 are two respectively. The left and right ends of the stabilizing roller body 1 are rotatably connected to the inside of the shaft rotation hole 32 opened in the inner hole block 31, so that the stabilizing roller body 1 can evenly disperse the impact force when it is impacted by the strip steel, reduce the damage caused by excessive force at a single point, and improve the durability and reliability of the stabilizing roller.
[0029] As a further implementation of this solution, the guide groove 22 is shaped as a three-section rectangle. The guide groove 22 passes through the left and rear ends of the bracket 21. The upper and lower ends of the guide groove 22 on the bracket 21 are fixedly connected to hydraulic rods 23. There are two hydraulic rods 23, two fixed connecting plates 24 and two dampers 25. The upper and lower ends of the inner hole block 31 are in contact with the damper 25. This symmetrical design ensures the uniform distribution of force during buffering and shock absorption, reduces equipment displacement or damage caused by asymmetrical force, and allows for real-time adjustment of the distance of the inner hole block 31 to ensure the stability of the inner hole block 31 on the horizontal plane.
[0030] As a further implementation of this solution, the inner hole block 31 is rectangular in shape, the shaft rotation hole 32 is cylindrical in shape, the shaft rotation hole 32 penetrates the inner side of the inner hole block 31, the connecting square plate 33 is rectangular at both ends, the connecting square plate 33 is slidably connected to the inner side of the guide groove 22 opened in the bracket 21, the connecting square plate 33 has a cylindrical through hole on the inner side near the displacement monitoring component 4, the connecting square plate 33 is fixedly connected to the front end and the rear end of the inner hole block 31, the number of displacement monitoring components 4 is the same as the number of connecting square plates 33, the column shell 41 is fixedly connected to the inner side of the through hole of the connecting square plate 33, the rear displacement monitoring component 4 has the opposite structural layout to the front displacement monitoring component 4, which facilitates the inner hole block 31 to slide on the inner side of the bracket 21 after the stabilizing roller body 1 is impacted by the strip steel, and the movement direction of the inner hole block 31 can be controlled by the limiting of the connecting square plate 33;
[0031] As a further implementation of this solution, the first magnetic block column 44 is slidably connected to the inner side of the cylindrical slide 42 opened in the column shell 41, one side of the rubber column 45 is attached to the side of the pressure sensor 43, the second magnetic block column 46 and the first magnetic block column 44 are magnetically repelled, the pressure sensor 43 is electrically connected to the hydraulic rod 23 through the controller, which can monitor the movement of the stabilizing roller body 1 in real time, and determine the impact force on the stabilizing roller body 1 when the pressure sensor 43 is subjected to pressure, thereby accurately controlling the extension length of the hydraulic rod 23.
[0032] Working process: During the shock absorption and buffering process of the stabilizing roller body 1 to prevent resonance of the strip, when the stabilizing roller body 1 is conveying the strip, the stabilizing roller body 1 is rotatably connected to the inner side of the shaft rotation hole 32. The stabilizing roller body 1 will move when impacted by the strip. The movement of the stabilizing roller body 1 will drive the inner hole block 31 to move. The inner hole block 31 is slidably connected to the inner side of the guide groove 22 opened in the bracket 21 through the connecting square plate 33. At this time, the inner hole block 31 will move a certain distance. The inner hole block 31 impacts the damper 25 attached to the lower end. The damper 25 reduces vibration and buffers the inner hole block 31. At the same time, under the action of inertia, the first magnetic block column 44 will move upward. The first magnetic block column 44 slides on the inner side of the cylindrical slide 42 opened in the column shell 41. The first magnetic block column 44 will drive the rubber column 45 to move upward. The rubber column 45 will squeeze the pressure sensor 43. After the pressure sensor 43 senses the pressure, it controls the hydraulic rod 2 at the lower end through the existing controller. 3. Upon startup, the greater the pressure value received by the pressure sensor 43, the greater the extension length of the hydraulic rod 23. The pressure value of the pressure sensor 43 is proportional to the extension distance of the fixed connecting plate 24. The lower hydraulic rod 23 drives the fixed connecting plate 24 and the damper 25 to move upward simultaneously. The damper 25 pushes the inner hole block 31 to move upward. Under the thrust of the damper 25, the inner hole block 31 can significantly reduce its swaying on the horizontal line. When the stabilizing roller body 1 moves upward due to inertia, the displacement monitoring component 4 at the rear end detects the movement of the stabilizing roller body 1 in real time, and limits the displacement of the stabilizing roller body 1 through the upper hydraulic rod 23, fixed connecting plate 24 and damper 25. This not only achieves the buffering and vibration reduction effect of the stabilizing roller body 1, but also prevents the stabilizing roller body 1 from resonating due to displacement caused by buffering and vibration reduction, ensuring the stability of the stabilizing roller body 1 when conveying strip steel and ensuring that the quality of the strip steel is not affected.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
