Abstract

The utility model is suitable for the technical field of powder spraying devices, and discloses a sheet metal powder spraying device which comprises a powder spraying operation room, a sheet metal conveying track, a reciprocating driving assembly, a powder spraying assembly, a first powder collecting pipe, a cyclone separator, a dust extraction fan and a collecting box. In the powder spraying process, the dust extraction fan is kept in an on state, so that powder which drifts in a powder spraying operation room can be pumped into the cyclone separator through the first powder collecting pipe, and the powder can be separated from air flow through gas-solid separation treatment of the cyclone separator and falls into the collecting box from a discharge hole at the bottom of the cyclone separator to be collected, and therefore the powder can be effectively collected. Moreover, because the powder that drifts in the powder spraying operation room can be sent to the cyclone through the first powder collecting pipe, the powder is difficult to scatter outside the powder spraying operation room through the feed inlet and the discharge outlet of the powder spraying operation room, thereby reducing the powder waste and avoiding the problem of environmental pollution.
