After the cutting is completed, the PET board directly falls to the ground through the drop port. At the same time, the linear moving mechanism 7 drives the cutting mechanism 8 to reset. Due to the falling of the PET board, the pressure sensor 6 is no longer under pressure. At this time, the conveyor belt 1 restarts the conveying action, thereby realizing the cutting operation of all PET boards in a reciprocating manner.
