The invention discloses a mechanism for stacking scattered cutter workpieces quickly and orderly. The mechanism comprises a stacking box, one side of the upper end of the stacking box is provided witha cutter feeding port, the outer side of the cutter feeding port is provided with a U-shaped baffle cover, the open side of the baffle cover is provided with a slideway, the low-position end of the slideway is rotatably connected with the stacking box, a support block is placed below the high-position end, and a first-level cutter conveying belt, a second-level cutter conveying belt and a third-level cutter conveying belt are sequentially arranged in the inner cavity of the stacking box from top to bottom and driven by a first driving motor, a second driving motor and a third driving motor respectively; the densities of clapboards on the first-level, second-level and third-level cutter conveying belts are sequentially increased. The mechanism is simple in structure and reasonable in design, through the design of the first-level, second-level and third-level cutter conveying belts, selected unqualified products and newly-transformed qualified products can be quickly stacked, manual stacking is replaced, the potential safety hazards are eliminated, and the production efficiency is improved.
