The utility model discloses a kind of roller mechanism of drawing frame, including equipment frame, first roller body, motor, mounting portion, sleeve, two second roller bodies, two groups of elastic members, swing arm, press roll, guide circle. First make press roll keep loose state, guide sliver through sleeve surface;Make press roll into working condition again, cooperate to sleeve extrude sliver, form roller pressure position. When sliver passes through roller pressure position, with the change of sliver thickness, sleeve can be offset up and down, sleeve offset keeps and the adhesion of two second roller bodies in the process, two roller bodies pass friction to the rotation of first roller body to sleeve, make sleeve rotate, drive sliver to pass through roller pressure position, while press roll also follow rotation. With beneficial effect: the change of sliver thickness can better adapt, improve roller pressure effect.
