Compared with the long-distance pushing of the silicon steel strip to realize feeding and feeding, the short-distance pushing and the subsequent automatic dragging and feeding are matched, so that the feeding speed is increased, and the probability of deformation of the silicon steel strip is reduced by shortening the moving path of the silicon steel strip in a bottomless supporting state, so that the influence on the subsequent shearing quality is avoided.
