Hole-threading Mechanism for Portable Paper Bag and Installation Method of Hand Rope

Abstract

The invention relates to a portable paper bag processing device and method. A portable paper bag punching and stringing mechanism comprises a cutting board, a folding clip tube, an elastic clip arranged in the folding clip tube in a penetrating mode, a first driving mechanism driving the elastic clip to stretch out and draw back in the folding clip tube and a second driving mechanism driving the folding clip tube to be opened and closed relative to the cutting board. An edge portion is arranged at the end, facing the cutting board, of the folding clip tube. The cutting board comprises a fixed half portion and a movable half portion hinged to the fixed half portion, a clip via hole is formed between the fixed half portion and the movable half portion, and the elastic clip is aligned to the clip via hole. The portable paper bag punching and stringing mechanism can complete bag body punching and stringing motion synchronously. The invention provides a portable paper bag carrying rope installation method carrying out punching and stringing in one procedure. Thus, the problems of low production efficiency and poor quality stability due to manual stringing are solved, and the problems that punching and stringing are carried out in a separation mode and consequently the number of procedures is large, large production sites are occupied and production management is inconvenient are solved.

Description
