[0024] A side beam frame 7 is fixed on one side of the top wall of the top plate 1, and the fixing method is that bottom support columns 8 are welded on both sides of the bottom wall of the side beam frame 7, and the two bottom support columns 8 are welded on the top plate 1, so as to ensure the stability of the side beam frame 7 and all structures thereon; A first servo motor 9 is horizontally installed on one side wall of the side beam frame 7, and a side groove 10 is formed on one side of the side beam frame 7 facing the cold-rolled steel strip 6, a first screw 11 is coaxially connected with the output shaft of the first servo motor 9, the first screw 11 is horizontally arranged in the side groove 10, and the first screw 11 is rotatably connected with the side beam frame 7 on both sides, so that the first screw 11 can stably rotate under the drive of the first servo motor 9, a side moving seat 12 is threadedly sleeved on the first screw 11, and the side moving seat 12 is attached to the inner wall of the side groove 10, and the part of the side moving seat 12 extending out of the side groove 10 is vertically designed;

[0025] A second servo motor 13 is vertically installed on the top wall of the side moving seat 12, and a side groove 14 is formed on the side of the side moving seat 12 facing the cold-rolled steel strip 6. A second screw rod 15 is coaxially connected to the output shaft of the second servo motor 13, and the second screw rod 15 is vertically arranged in the side groove 14 and rotatably connected to the side moving seat 12 on both sides. The second screw rod 15 can stably rotate under the drive of the second servo motor 13. The main drive motor 5, the first servo motor 9 and the second servo motor 13 all need external power supply. A sliding seat 16 is threadedly sleeved on the second screw rod 15 and abuts against the inner wall of the side groove 14, so that the second screw rod 15 can drive the sliding seat 16 to ascend and descend along the inner wall of the side groove 14 when the second screw rod 15 rotates;
