The invention discloses a dusting machine for leather processing. The dusting machine comprises a base, the four corners of the bottom of the base are welded to the tops of four supporting legs respectively, and the two sides of the top of the base are fixedly connected to the bottoms of suction fan boxes through screws respectively; suction fans are installed at the bottoms of the inner walls ofthe two suction fan boxes, dust baffles are welded to the upper portions of the inner walls of the suction fan boxes, and the middle of each dust baffle is connected with one end of a corresponding suction fan box suction pipe through penetration and insertion; a filter screen is clamped to the inner wall of each suction fan box suction pipe, a suction opening is formed in the upper portion of oneside of each suction fan box and welded to one end of the corresponding suction pipe, the other end of each suction pipe is welded to one side of a dust removal box, and the bottom of the dust removal box is fixedly connected with the top of the base through a screw. According to the dusting machine for leather processing, when an arranged stepping motor runs, a brush rotates back and forth on leather, and the dusting effect of the dusting machine is improved; by arranging a fixing plate, under the effect of a spring, the leather is fixed on a fixing table and prevented from sliding under stress in the dust removal process.
