The second clamping plate (32) is rotatably mounted on the movable sleeve (2). The first clamping plate (31) is fixedly connected to the movable sleeve (2). The clamping plate hydraulic cylinder (33) is used to drive the second clamping plate (32) to rotate so as to clamp the working roller bearing seat (61) between the first clamping plate (31) and the second clamping plate (32).

6. The roll adjusting device as described in claim 1, characterized in that, The piston rod of the hydraulic cylinder (1) is detachably connected to the movable sleeve (2) at the end away from the bending roller block (7).

7. The roll adjusting device as described in claim 1, characterized in that, It also includes a bending roller mechanism, which includes a bending roller block (7), an upper bending roller hydraulic cylinder (8), a lower bending roller cylinder body (9), and a connecting rod. The bending roller block (7) is used to be mounted on the frame (100). The upper bending roller hydraulic cylinder (8) and the lower bending roller cylinder body (9) are mounted vertically within the bending roller block (7). The piston rod of the upper bending roller hydraulic cylinder (8) is connected to the lower bending roller cylinder body (9) through the connecting rod. The cylinder body of the upper bending roller hydraulic cylinder (8) and the lower bending roller cylinder body (9) are used to act on the extension arm (62) of the work roller bearing seat (61).

8. The roll adjusting device as described in claim 7, characterized in that, The bent roller block (7) is provided with a second limiting groove structure (71) at one end facing the frame (100), and the second limiting groove structure (71) is used to accommodate the end of the frame (100) facing the work roller (6).
