[0031] When the cold-rolled strip is running, two motors 5 are started respectively, and the motor 5 is used to drive the threaded rod 6 to rotate, so that the slider 7 and the mounting frame 8 move toward the side close to the strip. According to the different widths of the strip, the running distance of the slider 7 is controlled to meet the use requirements of strips of different widths.

[0032] After the slider 7 runs to the set position and stops, the side and bottom of the strip are in contact with the rotating member 10. The rotating member 10 limits the strip, thereby avoiding deviation during the operation of the strip. While the strip is running, the rotating member 10 rotates synchronously to guide the strip and reduce the resistance encountered by the strip during operation.

[0033] In this embodiment, the guide mechanism 3 further includes a slide rail 11 , which is disposed on the support block 2 , and the slider 7 is disposed on the slide rail 11 , so as to improve the stability of the operation of the slider 7 .

[0034] In this embodiment, a limit block 12 is provided at one end of the threaded rod 6 away from the support plate 4 , and the threaded rod 6 is rotatably connected to the limit block 12 , and the limit block 12 serves to limit the operation of the slider 7 .

[0035] In this embodiment, a second rotating rod 13 is arranged between the two limit blocks 12, and a first rotating wheel 14 is arranged on the second rotating rod 13. Multiple first rotating wheels 14 can be arranged according to usage requirements, and the first rotating wheel 14 is used to support the lower end of the strip.

[0036] In this embodiment, a driving mechanism 15 is provided on the gantry 1, and the driving mechanism 15 includes a cylinder 16 and a lifting plate 17. The cylinder 16 is provided on the gantry 1, and the cylinder 16 drives the lifting plate 17 to move closer to or away from the support block 2. A pressing mechanism 18 is provided on the lifting plate 17, and the lifting plate 17 is driven up and down by the cylinder 16, so that the pressing mechanism 18 presses against the upper end of the strip to prevent the strip from warping during operation.

[0037] In this embodiment, telescopic rods 19 are respectively provided on both sides of the cylinder 16 , one end of the telescopic rod 19 is connected to the gantry 1 , and the other end of the telescopic rod 19 is connected to the lifting plate 17 . The telescopic rod 19 is used to improve the stability of the pressing mechanism 18 .

[0038] In this embodiment, the pressing mechanism 18 includes a limit plate 20, a third rotating rod 21 and a second rotating wheel 22. Two limit plates 20 are symmetrically arranged. The limit plate 20 is arranged on the lifting plate 17, and the third rotating rod 21 is arranged between the two limit plates 20. The second rotating wheel 22 is arranged on the third rotating rod 21. Multiple second rotating wheels 22 can be arranged according to needs. When in use, the cylinder 16 drives the lifting plate 17 to move downward until the second rotating wheel 22 stops after it presses against the upper end of the strip. During the operation of the strip, the second rotating wheel 22 rotates synchronously.

[0039] In this embodiment, a buffer assembly 23 is provided between the limiting plate 20 and the lifting plate 17 , and the buffer assembly 23 plays a buffering role to prevent the second rotating wheel 22 from damaging the strip steel.

One end of the slide bar 24 is connected to the limit plate 20, and the other end of the slide bar 24 passes through the lifting plate 17. The spring 25 is sleeved on the slide bar 24, and the spring 25 is located between the lifting plate 17 and the limit plate 20. The limit piece 26 is arranged at one end of the slide bar 24 away from the limit plate 20. The limit piece 26 limits the slide bar 24. When the strip steel runs abnormally, the strip steel will exert a force on the second rotating wheel 22. At this time, the limit plate 20 squeezes the spring 25, and the slide bar 24 slides upward. After the strip steel runs normally, the spring 25 rebounds and the slide bar 24 slides downward, thereby realizing force buffering.

[0041] Working principle of a cold-rolled strip centering device according to an embodiment of the present application:

[0042] When the cold-rolled steel strip is running, two motors 5 are started respectively, and the motor 5 is used to drive the threaded rod 6 to rotate, so that the slider 7 and the mounting frame 8 run to the side close to the steel strip. After the slider 7 runs to the set position and stops, the side and bottom of the steel strip are in contact with the rotating member 10. The rotating member 10 limits the steel strip, thereby avoiding the deviation of the steel strip during operation. While the steel strip is running, the rotating member 10 rotates synchronously to guide the steel strip and reduce the resistance encountered during the operation of the steel strip. The above is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and changes. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
