The utility model provides a roller of a wire-stripping machine, and belongs to the technical field of wire-stripping machines. The technical problems that an existing wire-stripping machine rolling shaft is insufficient in holding power, prone to abrasion and slipping and the like are solved. A wire stripping machine roller comprises a shaft body, a plurality of roller bodies arranged in the axial direction in a non-equidistant mode are integrally formed on the shaft body, each roller body is provided with an outer circumferential face coaxial with the shaft body and an inclined face connecting the outer circumferential face with the shaft body, and every two adjacent inclined faces and the shaft body form a feeding groove. A plurality of axially-arranged stepped sawtooth rings are arranged on the inclined face, and the peripheral diameters of the sawtooth rings are gradually decreased in the direction close to the bottom of the feeding groove. The utility model has the advantages of super-strong holding power, slip prevention, wear resistance and the like.
