The strip enters the expansion shaft 16 from the outlet deflection roller 11. As the number of coils increases, the radius of the expansion shaft 16 increases accordingly. During the operation of the reducer 14, in order to prevent the strip from deviating, the centering cylinder 15 drives the reducer 14 and the expansion shaft 16 to extend and retract, so that the strip is always in the center of the expansion shaft 16; when the coiling is completed and ready to be unloaded, the swing cylinder 12 drives the movable support 13 to open, and the coil after rolling is unloaded from the operating side.
[0025] The flattening roller device comprises a base 1, an axle seat 2, a rotating shaft 3, a flattening roller 4 and a power device 6;
[0026] Two shaft seats 2 are fixedly arranged on the base 1, and the two shaft seats 2 are rotatably connected with a rotating shaft 3. A pressing roller 4 is arranged at the other end of the rotating shaft 3 away from the shaft seat 2, and the power device 6 drives the rotating shaft 3 and drives the pressing roller 4 to rotate. Specifically, Figure 4-5 As shown, the base 1 is fixed on the chassis of the reducer 14 through a connecting plate.
[0027] The rotating shaft 3 is arranged parallel to the pressure roller 4, and the two ends of the pressure roller 4 are rotatably connected to the large swing arm 5. The other end of the large swing arm 5 away from the pressure roller 4 is arranged on the rotating shaft 3 and fixedly connected to the rotating shaft 3. A large swing arm 5 is respectively arranged at both ends of the rotating shaft 3, and the distance between the rotating shaft 3 and the large swing arm 5 is greater than or equal to the distance from the expansion shaft 16 to the rotating shaft 3.

Specifically, Figure 2 As shown, the side shape of the small swing arm is a rounded triangle. The base 1 is stepped, the swing arm oil cylinder is arranged at the lower layer, and the shaft seat 2 is arranged at the upper layer.
[0029] The swing arm oil cylinder is a prior art. In this embodiment, a proportional valve is provided on the swing arm oil cylinder. When the pressure roller 4 is subjected to the force of the coiled material on the expansion shaft 16, the proportional valve adjusts the output of the swing arm oil cylinder to avoid retraction.
