The invention relates to the technical field of equipment related to bristle processing, and discloses a wool carding device for bristle processing. The device comprises a transverse plate, wherein the bottom of transverse plate is fixedly provided with supporting legs, the middle of the upper surface of the transverse plate is fixedly provided with a supporting rod, the back face of the supporting rod is movably sleeved with a roller, the back face of the supporting rod is movably sleeved with a driven rotating wheel, the front face of the roller is fixedly connected with the back face of thedriven rotating wheel, the left side of the upper surface of the transverse plate is fixedly provided with a placing box, and the bottom of the inner wall of the placing box is in movably sleeved connection with a rotating cylinder through the supporting rod. The wool carding device for bristle processing has the advantages that an L-shaped rod on a partition plate provides convenience for bristles in the placing box to be scattered on a conveyor belt in equal quantity; a cylinder provides convenience for a small number of unevenly distributed bristles to be extruded to be even, thereby providing convenience for the bristles to be evenly transferred onto a wool division box in equal quantity, and then providing convenience for even and reasonable wool carding through a tapered rod.
