the strip steel with edge cracks passes through a rolling production line, the strip steel with edge cracks is arranged between the two grinding heads 5, the second driving mechanism 21 rotates, and the belt 24 connects the second driving mechanism 21 with the lead screw 22, so that the lead screw 22 rotates along with the second driving mechanism, the rotating lead screw 22 drives the rotating shaft 411 to move towards the strip steel along the width direction of the strip steel, and the two grinding heads 5 are close to the strip steel; when the grinding head 5 contacts with the side part of the strip steel in the width direction, the second driving mechanism 21 stops rotating, the first driving mechanism 6 works to drive the grinding head 5 to rotate, so that the grinding head 5 grinds the edge crack defect of the strip steel, under the action of the gravity of the balancing weight and the flexible piece 42, the gravity of the balancing weight becomes the pulling force of the flexible piece 42 to the rotating piece 41, and the pulling force gives a first moment to the rotating shaft 411 of the rotating piece 41 through the convex ring 44; when the grinding head 5 is in contact grinding with the edge crack defect of the strip steel, the grinding head 5 applies an acting force to the edge crack defect of the strip steel, meanwhile, the grinding head 5 bears a reaction force of the edge crack defect of the strip steel, and the reaction force applies a second moment to the rotating piece 41 through the swinging piece 3; therefore, the rotating member 41 simultaneously bears a first moment formed by the tension of the flexible member 42 and a second moment of the strip steel to the rotating member 41, the rotating member 41 keeps balance under the combined action of the first moment and the second moment, the gravity of the counterweight 43 is constant, namely the first moment is constant, in order to keep balance, the second moment is also constant, when the grinding heads 5 contact with the strip steel edge crack defect, namely the crescent arc defect, the grinding heads 5 always apply constant acting force to the strip steel, so that the grinding heads 5 can adapt to the strip steel edge crack defect, provide constant pressure, and ensure the stability of the grinding quality of the strip steel edge crack defect.
It should be noted that, because the arc edge crack defect of the strip steel makes the range of the adaptive angle adjustment of the oscillating piece 3 very small, the angle between the acting force applied to the arc edge crack defect of the strip steel by the grinding head 5 and the oscillating piece 3 is not changed. The rotating direction of the grinding head 5 is related to the rotating speed of the grinding head 5, and when the grinding head 5 rotates and grinds at a low speed (the linear speed is less than or equal to 30 m/min), the linear speed of one side, close to the strip steel, of the grinding head 5 is consistent with the running direction of the strip steel; when the grinding head 5 rotates and grinds at a high speed (the linear speed is more than 30m/min and less than or equal to 300 m/min), the linear speed of the grinding head 5 close to one side of the strip steel is opposite to the running direction of the strip steel.
