The invention discloses a printing wheel device used for cable sheath printing. The printing wheel device is provided with a printing wheel, and further comprises a printing wheel position regulating device which is composed of a fixing frame and a printing wheel regulating frame, wherein the fixing frame consists of two barrel type supporting legs and a fixing plate; the printing wheel regulating frame consists of two regulating supporting legs which can be inserted into the two barrel type supporting legs and a connecting beam; screw caps are arranged at the top ends of the two regulating supporting legs; a regulating screw is screwed into the screw caps at the top ends of the two regulating supporting legs; a fixing ring is screwed on the regulating screw; the printing wheel is arranged on the fixing ring; a stud is fixedly arranged on the fixing plate; a jacking screw cap is screwed on the stud; the bottom of the connecting beam is correspondingly provided with a jacking plate; and a jacking spring is connected between the jacking plate and the jacking screw. According to the printing wheel device, when the position of the printing wheel is required to move left and right, only the fixing ring is required to rotate; when the height of the printing wheel is required to regulate up and down, the jacking screw cap on the stud is rotated; besides, the jacking spring can guarantee clear printing, and can avoid a cable sheath from being damaged.
