Aluminum fragment collecting device

The utility model provides an aluminum fragment collecting device which comprises an inclined guide pipe, the guide pipe is a square pipe, an opening of the inclined upper end of the guide pipe is in arc transition to the horizontal direction, and a plurality of air inlet holes inclining downwards are formed in the top of the arc transition section of the guide pipe. And the air inlet is connected with an external air source through a pipeline. The guide pipe is reasonable in design, the slitter edges are directly guided into the slitter edge machine through the guide pipe, the surface quality problems that the slitter edges are prone to flying up in the falling process, are extremely prone to jumping into a bearing seat or being rolled into a cutter shaft and the like and are rolled into the bearing seat or the cutter shaft and the like, so that the slitter edges are stuck and shut down, or the slitter edges are pressed into the surface of a roller way and the like are solved, and specialized production is f
