In the process of the operation of the slitting line, motors of the feeding, slitting, tensioning and other mechanisms are in polar speed regulation and work independently, so that the feeding, feeding and discharging steps in all the working procedures are easy to be inconsistent. If the unwinding speed and the winding speed cannot be adjusted in time, the balance of unwinding, winding and slitting speeds of the slitting machine is maintained, silicon steel sheets are easily accumulated between the material guiding section and the slitting section, the slitting section and the winding section, the effect of slitting is easily influenced, and the silicon steel strips are likely to be pulled to deform or break due to untimely adjustment, so that waste is caused.

In view of this problem, the existing slitting line is generally solved by providing a buffer pit, and if the silicon steel sheet falls too deeply in the buffer pit, the silicon steel sheet may be deformed due to excessive bending or stretching by gravity, thereby affecting the performance thereof, and if the buffer length is not sufficient, the material strip may be easily stretched and damaged between the unreeling machine and the guiding machine, so that improvement is required.
