in a normal state, the surface of the PS plate 8 has no folds and bulges, the electromagnetic rod 494 slides towards the middle direction from the bending position of the PS plate 8 without generating obstruction, the baffle 495 and the electromagnetic rod 494 synchronously slide, the suction force of the suction groove 6 covered by the baffle 495 is kept in a low state, the suction force of the position where the suction groove 6 is not covered by the baffle 495 is enhanced, and the PS plate 8 at the position where the baffle 495 is not covered is flattened by the electromagnetic rod 494, so that the suction force of the flattening position is enhanced at the same time after the PS plate 8 is flattened, thereby ensuring the stability and the flatness when the PS plate 8 is bent;
if the surface of the PS plate 8 has wrinkles or is low in bulge, the electromagnetic rod 494 gradually rolls the upwarping condition on the top of the PS plate 8 in the sliding process;
if folds or bulges exist on the surface of the PS plate 8, and the electromagnetic rod 494 is slightly lifted under the influence of the tilting position, if the electromagnetic rod 494 is forcedly rolled on the tilting position of the surface of the PS plate 8, the surface of the PS plate 8 is easily damaged, when the electromagnetic rod 494 is separated from the top of the lower jaw edge 401, the folds of the PS plate 8 are separated from the top of the lower jaw edge 401, the electric control system 3 controls the bent plate cylinder 48 to reset, and the electromagnetic rod 494 pulls back the PS plate 8 again for positioning;
after the PS plate 8 is bent, the electric control system 3 controls the bending cylinder 48 to reset, the gear 47 rotates reversely to drive the bite upper knife edge 45 and the drag upper knife edge 43 to reset in a rotating manner, the top of the spring rod 499 is attached to one side of the plate body 498, and the plate body 498 stops rotating under the influence of the obstruction of the spring rod 499, so that the plate body 498 is attached to the bending position of the PS plate 8, the bending state of the PS plate 8 is kept, and the situation that the PS plate 8 rebounds after being bent is avoided;
when gear 47 counter rotation, gear 47 pulls baffle 495 and resumes to initial condition gradually, and baffle 495 blocks up suction slot 6 gradually promptly, and PS version 8 receives the adsorption affinity less, makes things convenient for the staff to take off PS version 8 and changes.
