s2, starting a conveying motor (21) to enable the conveying roller (15) to rotate, continuously pulling out steel under the action of the conveying roller (15), enabling the material roller (11) to rotate under the action of tensile force at the moment, and therefore achieving the effect of automatic conveying of materials;

s3, under the action of starting the rotation of the conveying motor (21), the winding shaft (212) is driven to rotate to wind the connecting rope (214) positioned on the winding shaft (212), when the connecting rope (214) is wound on the winding shaft (212), the torsion spring shaft (215) is driven to rotate at the moment, the torsion spring shaft (215) is driven to rotate to drive the reset spring column (219) to move, and the reset spring column (219) is driven to move to drive the sliding block (220) to move;

s4, when the sliding block (220) moves to a certain position to be in contact with the limiting block (217), the sliding block (220) is respectively abutted against the starting switch (216) and the closing switch (218), the starting switch (216) enables the slitting knife (36) to descend, the closing switch (218) enables the conveying motor (21) to stop rotating, the slitting knife (36) descends to slit steel, and on the premise that the outer diameter of the torsion spring shaft (215) is not changed, the moving distance of the reset spring column (219) is the same every time, so that the slitting distance of the steel every time is the same, and equidistant slitting is achieved;

s5, after the steel is cut, the cutting knife (36) is reset, and meanwhile, in the cutting process of the cutting knife (36), the torsion spring shaft (215) is reset because the torsion spring shaft (215) loses traction, and the reset spring column (219) is reset, so that the next cutting is facilitated;

s6, along with continuous slitting, the slitting knife (36) is worn to a certain extent at the moment and cannot slit steel normally, so that in the slitting process, the force born by the pressing plate (31) is increased, after the stress of the pressing plate (31) changes, before the next slitting, the slitting knife (36) is driven to rotate by the rotating motor (39), and the effect of automatically replacing the slitting knife (36) is achieved.
