Dust material packaging device with cooling function

The invention discloses a dust material packaging device with the cooling function. The dust material packaging device comprises a first fixed frame, a first motor, a spiral blade, a rotating shaft, avacuum pump and a packaging bag; and when dust materials enter into a screw transmission machine through a feed hopper, a first metal plate and a second metal plate are relatively arranged and the length direction is consistent with the width direction of the packaging bag, a second fixed frame is fixed on a board, the first metal plate is fixedly connected with one end of a push rod, the other end of the push rod is connected with the output shaft of a second motor, the two sides of the second metal plate are connected with positive and negative poles of an electric heater through wires, andischarge port is provided with the vacuum pump, so as to prevent the dust materials from escaping or floating into air during the blanking process, environmental pollution and material waste are avoided, when the materials ar
