Gantry line-to-linkage line system

The utility model discloses a gantry line-to-linkage line system which comprises a base and a linkage line frame, a plurality of conveying rollers arranged at equal intervals are arranged between the inner walls of the two ends of the linkage line frame, and the lower end of the linkage line frame is fixedly connected with two symmetrically-arranged fixing plates. Two symmetrically-arranged transverse rods are fixedly connected between the two fixed plates jointly, two symmetrically-arranged movable plates are slidably connected to the two transverse rods jointly, and limiting mechanisms used for limiting plates are arranged on the two movable plates correspondingly. And the limiting mechanism comprises a plurality of limiting rods which are fixedly connected to the upper end of the movable plate and are arranged at equal intervals. The linkage line frame is reasonable in structure, metal plates are limited through the limiting mechanism and the driving mechanism, it is guaranteed that the metal plates are lo
