The utility model discloses a kind of capping head, ring pull slide and its cap screwing
machine, to solve the deficiency that current cap screwing
machine is easy to cause press bending cover. The utility model includes material pushing rod and capping head body, capping head body includes capping neck, capping cylinder and capping horn, material pushing rod includes material pushing rod body and material pushing head, the bottom of capping cylinder is equipped with
counterbore adapting material pushing head, capping neck and capping cylinder are equipped with inner hole adapting material pushing rod body, along the direction of capping neck to capping horn, the inner
diameter of capping horn gradually increases, capping horn includes first guide section, step plastic section and second guide section, each place of first guide section and second guide section is continuously transition, and round corner is equipped between the
two step surfaces of step shaping. Material pushing head can completely enter into
counterbore, first guide section and second guide section provide more space and more guide to the inclined ring pull cover, drive the ring pull cover of lighter degree of deflection reset, reduce the probability of press bending cover condition.
