Background
The waste edge of the strip steel needs to be cut off during cold rolling, and the edge cutting and coiling technology of strip steel pickling is increasingly widely applied to a strip steel continuous pickling line. The trims are generally wound into trim coils by a coiler, and such trim coils are used as recycled steel resources, for example, for drawing steel wires. On a continuous pickling production line, a disc shear can be adopted to shear two sides of strip steel to generate trimming, the trimming firstly enters a trimming feeder and then is guided to a winding drum of a trimming coiler, and the trimming is automatically clamped and coiled. However, when the amount of the steel strip edge trim coiling reaches a certain amount, it is necessary to cut the steel strip edge trim coiling. However, the edge cutting of the strip steel to be cut has a high transmission speed, and the edge cutting of the steel is easy to damage the cutting knife.
