Plate processing line

The utility model discloses a plate processing line. The scrap removing device comprises a conveying device and a scrap removing device body arranged on a conveying path of the conveying device. The scrap removing device comprises two electric contact assemblies, each electric contact assembly comprises an electric contact piece made of a conductive material and a first lifting power piece used for driving the electric contact piece to ascend and descend, and the two electric contact pieces are electrically connected with the two electrodes of the working power source respectively and used forabutting against the top layer and the bottom layer of the plate respectively. When the plates stay on the conveying device or are conveyed on the conveying device; one electric contact piece abuts against the top layer of the plate downwards, the other electric contact piece abuts against the bottom layer of the plate upwards, the first electrode, the top layer, the chippings, the bottom layer and the second electrode f
