Description

technical field

[0001] The invention relates to the technical field of cutting, in particular to a cutting knife driving mechanism of a three-side book trimmer. Background technique

[0002] The movement of the cutting knife of the three-sided book trimmer is composed of such a group of cyclic actions as lifting, pausing and cutting; the driving mechanism of the cutting knife that is used more at present is an intermittent movement mechanism; a large gear drives a non- The complete gear, the offset pin on the non-complete gear is connected to a connecting rod, and the other end of the connecting rod is connected to the slider of the cutting knife, so that the cutting knife can lift, stop and cut; when the non-complete gear When the toothed part of the incomplete gear meshes with the large gear, the incomplete gear rotates, driving the connecting rod to move, and the cutting knife is lifted or cut off; when the toothless part of the incomplete gear is relatively large gear, t...
