Suction device for removing floating powder on surface of workpiece

The utility model discloses an absorbing and removing device for removing floating powder on the surface of a workpiece, which comprises a fixing frame arranged in a coded disc box, side plates are arranged on two sides of the fixing frame, demagnetizing coil blocks are mounted on the side plates, an accommodating space is formed between the two demagnetizing coil blocks, and the area, corresponding to the space between the two side plates, of the fixing frame is hollowed out. A powder collecting bin is arranged at the lower end, corresponding to the hollowed-out area, of the fixing frame, and when the demagnetizing coil block is powered on, the demagnetizing coil block generates attraction force to attract floating powder attached to the surface of a workpiece. When the demagnetizing coil block is powered off, floating powder on the surface of the demagnetizing coil block falls into the powder collecting bin under the action of gravity, and then full-automatic floating powder removing is achieved. 本实用新型公开了一种
