The working part of the rolling mill consists of upper and lower working rolls, and the upper and lower working rolls are respectively installed between two working roll bearing boxes. The plates are rolled to the required thickness by the two working rolls. When rolling at both ends of the plates, the lifting of the ends of the plates will scratch the surface of the working rolls, affecting the surface flatness of the working rolls, and thus causing the surface flatness of the plates produced subsequently.

[0003] At present, in order to solve the above problems, a guide plate is usually added between the two bearing boxes to protect the working rolls. The guide plate plays the role of guiding the plate, the plate biting into the roll gap of the working roll and protecting the roll surface of the working roll. However, the installation of the guide plate needs to be combined with the surface structure of the bearing box on the one hand, and on the other hand, when the working roll is ground after a period of work, the diameter of the working roll after grinding is reduced, and the height of the guide plate needs to be adjusted to be consistent with the working roll. The current guide plate device is either fixed in design or the height adjustment is troublesome. Summary of the invention

C-shaped grooves 7 are opened at both ends of the upper guide plate 5. When the upper guide plate 5 is installed, it is horizontally pushed from one side of the protrusion, and the C-shaped groove 7 is stuck on the protrusion 3. A plurality of gaskets 10 are arranged on the upper and lower sides of the protrusion 3. An upper adjustment steel plate 8 is arranged on the upper side of the gasket 10 located at the top, and a lower adjustment steel plate 9 is arranged on the lower side of the gasket 10 located at the bottom. The protrusion 3, gasket 10, upper adjustment steel plate 8 and lower adjustment steel plate 9 are all located in the C-shaped groove 7. The number of gaskets 10 located on the upper and lower sides of the protrusion 3 is the same or different, and the height of the upper guide plate 5 is adjusted by adjusting the number of gaskets 10 on the upper or lower side of the protrusion 3 to adapt to upper guide rollers 17 of different plates or diameters.

[0027] An adjusting bolt 11 and a screw 12 are provided on the outside of the C-shaped groove 7 . The adjusting bolt 11 and the screw 12 are threadedly connected with the corresponding protrusion 3 in the C-shaped groove 7 . The position of the upper guide plate 5 is fixed by the adjusting bolt 11 and the screw 12 .

[0028] A machined groove 4 is provided on the opposite side of the two lower bearing boxes 2, and a lower guide plate 6 is provided between the two grooves 4. A cushion block 13 is provided at the bottom of the groove 4, and the cushion block 13 is fixedly connected to the lower bearing box 2 by a fixing bolt 14. The two ends of the lower guide plate 6 extend into the corresponding groove 4, and a screw rod 15 is threaded through the upper and lower ends of the lower guide plate 6. The bottom of the screw rod 15 is rotatably connected to the cushion block 13, and a cover plate 16 is provided on the upper part of the groove 4. During installation, after the cushion block 13 is fixed by the fixing bolt 14, the lower guide plate 6 and the screw rod 15 are hoisted into the groove 4 from the top and placed on the cushion block 13. The height position of the lower guide plate 6 is adjusted by rotating the screw rod 15, and then the cover plate 16 is covered.

[0029] The upper guide plate 5 and the lower guide plate 6 correspond to each other up and down, and both the upper guide plate 5 and the lower guide plate 6 are located between the upper guide roller 17 and the lower guide roller 18, so that the rolled plate is guided and the roller surfaces of the upper working roller 17 and the lower working roller 18 are protected by adjusting the positions of the upper guide plate 5 and the lower guide plate 6.

[0030] When in use, first push the C-shaped grooves 7 on both sides of the upper guide plate 5 horizontally corresponding to the protrusions 3, so that the C-shaped grooves 7 on both sides of the upper guide plate 5 clamp the protrusions 3, and adjust the number of gaskets 10 on the upper and lower sides of the protrusions 3 according to the thickness of the plate and the diameter of the upper working roller 5 to complete the height position adjustment of the upper guide plate 5, and then fix the upper guide plate 5 by adjusting the bolts 11 and the screws 12.
