[0057] Working principle: When the shearing device is cutting the steel coil, the conveying motor 404 can be started to drive a conveying shaft 402 to rotate. The rotation of one conveying shaft 402 drives the other conveying shaft 402 to rotate synchronously in the opposite direction under the action of two transmission gears 405, thereby driving the two rubber conveying rollers 403 to rotate synchronously in the opposite direction, so as to realize the purpose of automatically conveying the steel coil, so that the steel coil passes through the middle of the two rotating disks 201, and is cut by the two cutting knife assemblies 202 at the bottom of the upper rotating disk 201 and the top of the lower rotating disk 201, and is cut in several rings. The steel coil is automatically cut into a number of steel coil strips under the action of the shaped cutter 2022. When steel coils of different shapes and specifications need to be cut, the drive motor 204 can be started. The rotation of the drive motor 204 drives the two connecting shafts 205 to rotate toward each other at the same time under the action of the first toothed disc 207, the two connecting toothed discs 2011 and the second toothed disc 209, thereby driving the two rotating discs 201 to rotate toward each other synchronously, thereby realizing the automatic switching of the cutter assemblies 202 on the two rotating discs 201, and being able to quickly cut steel coils with different requirements, thereby effectively improving work efficiency.
