Abstract
The present disclosure provides a tape cutting device in a carton sealer. The device includes a cutter holder, a fixed blade and a movable blade. The movable blade slides to the fixed blade to cut off a tape, and a cutting edge of the movable blade is designed to be of an isosceles triangle structure. This way can reduce a resistance caused by cutting the tape by using the movable blade, and is also beneficial to the conservation of electric energy required by a cutting motor. In addition, by sensing a position of an eccentric pin through a distance sensor in a process that the tape is cut off, the movable blade can automatically reset to be away from the fixed blade, which is convenient for re-packaging and cutoff.
