The utility model belongs to the field of packaging production, particularly relates to a
distance detection device for a continuous packaging bag
cutting machine, and aims to solve the problem that the existing device cannot accurately judge whether the packaging
cutting operation is qualified or not due to the fact that whether a cutter touches medicines in a
package or not in the
cutting process or not cannot be accurately monitored in real time. Two fixing columns are symmetrically arranged on the two sides of the bottom of the tool rest in a penetrating and sliding mode, and the same connecting base is fixedly arranged outside the two fixing columns. A cutting-off
assembly is arranged on the tool rest and used for breaking and cutting off continuous packaging bags, and a detection
assembly is arranged on the connecting base and used for judging whether
medicine in the packaging bags is
cut off or not. Through the arrangement of the detection
assembly, whether the cutter touches the
medicine in the
package or not when cutting off the packaging bag is accurately monitored in real time, whether the
package cutting operation is qualified or not is rapidly judged, the quality consistency of product packaging is guaranteed, and the quality and safety of packaged products are guaranteed.
