The invention relates to a safety roller aligning machine. The safety roller aligning machine comprises a rack, a feeding hopper, a material receiving hopper and two extrusion rollers. The material receiving hopper is arranged below the feeding hopper. The two extrusion rollers can be embedded in the lower portion of the feeding hopper in an opposite rotation manner. The two ends of each of the two extrusion rollers are connected with the rack. The two extrusion rollers are in a cylinder shape. A plurality of extrusion strips are evenly distributed on the surface of each extrusion roller, andeach extrusion strip is welded to the corresponding extrusion roller where the extrusion strip is located. When the two extrusion rollers rotate, the extrusion strips close to one another are constantly kept engaged. The parts, corresponding to the upper ends of the two extrusion rollers, of the two sides of the feeding hopper are connected with baffles. Compared with the prior art, the safety roller aligning machine is simple in structure, low in cost and long in service life; and the baffles can protect the two extrusion rollers, and operators are prevented from being hurt by the two extrusion rollers.
