Cutting mechanism of plate cutting machine

The utility model provides a cutting mechanism of a plate cutting machine, which relates to the technical field of plate cutting machines and comprises a base, a plurality of support rods are fixedly mounted on the outer surface, close to the top, of the base, and conveying rollers are movably embedded in the opposite surfaces of the plurality of support rods. When the plate cutting device is used, a plate needing to be cut is placed on the outer surface of the first conveying belt, then an electric telescopic rod is started to drive a limiting plate to adjust, the plate can be better attached to the first conveying belt, the situation that the two sides of the plate tilt up when the plate is cut can be exactly prevented, a first motor is started to drive a first pulley to rotate, and the plate is cut. The first pulley rotates to drive the belt to rotate, the belt drives the second pulley movably embedded in the other end to rotate, the second pulley and the first pulley rotate to drive the conveying rollers
