Plate material production line

The utility model discloses a plate material production line. The production line comprises a plate shearing machine, a transition guide roller rack and a traction machine which are sequentially arranged, wherein a cutting platform is arranged on the plate shearing machine; a guide roller buffering device is arranged between the plate shearing machine and the transition guide roller rack; the guide roller buffering device comprises two mounting plates which are connected with the cutting platform and oppositely arranged; chutes are correspondingly formed in the two mounting plates; a plurality of sliding guide rollers are arranged in the chutes, and can slide in the chutes by virtue of sliding blocks; and two adjacent sliding blocks are connected by virtue of a spring. According to the plate material production line, the surface quality of a sheet can be protected, occurrence of a condition that a transition guide roll is blocked by the sheet can be avoided, the production of a sheet material production line can be smooth, and the production efficiency can be guaranteed.
