The invention discloses a laser texturing processing method on the surface of a roller, comprising the following steps: leading the roller to rotate with uniform velocity along self axes; simultaneously, leading a laser texturing head to move with uniform velocity along the axial direction of the roller; and periodically transmitting laser beam to the surface of the roller and forming texturing spots on the surface of the roller. The method is characterized in that by accelerating the moving speed V of the laser texturing head along the axial direction of the roller, the texturing spots are distributed along the high inclination-angle helical line with the thread pitch of delta being equal to 2-200mm on the roller. As the roller has no smooth straight line between the two rows of the texturing spots on the circumference of the surface of the roller, when rolling a steel plate, the roller and the steel plate can prevent from jointing at those parts, the iron slag grains can be absorbedby texturing concave holes crisscross distributed on the peripheral direction of the roller, scratch can not be produced on the length direction of the steel plate, and the iron slag grains can not fray and break the texturing spots, thereby greatly improving the rolling quality of the steel plate and the wearing resistance of the roller, and prolonging the service life of the roller.
