The invention relates to a novel powder collecting device for strip materials. The novel powder collecting device comprises a rack, and a pressing mechanism, a receiving mechanism and a cutting mechanism which are installed on the rack; the pressing mechanism is slidably installed on the rack, and reciprocates at the upper part of the cutting mechanism; and the lower part of the pressing mechanismis provided with the receiving mechanism, and the receiving mechanism comprises a fixing frame, a scraping plate, a horizontal drive rodless cylinder and a vertical drive cylinder. The novel powder collecting device has the advantages that materials are not displaced relative to each direction of a cutting station, and powder is horizontally collected at this station through the receiving mechanism directly. After collection of the materials, the regularity is high, thereby benefiting implementation of subsequent working procedures.
