Description

Edge inserting machine for packaging bag Technical Field The utility model relates to the technical field of packaging machinery, in particular to a packaging bag edge inserting machine. Background In the packaging industry, flexible packages are often required to have printed designs or text on their surfaces during the manufacturing process. After printing, the two side edges of the packaging bag need to be folded inwards, which is called edge inserting, in order to facilitate subsequent stacking, storage and transportation space saving. The traditional edge inserting process mostly adopts a mechanical folding or manual auxiliary folding mode. However, the prior art has the obvious defects that firstly, the printed packaging bag material has a certain elastic memory effect, after the two sides are folded inwards, the folded edges are extremely easy to elastically rebound, so that the two side edges cannot be tightly attached to a bag body, uneven edge warping and the like occur, and secondly, due to the existence of an ink layer on the surface of the packaging bag and the physical characteristics of a film, the folded edges are difficult to permanently shape by simple mechanical extrusion, and the appearance quality and the subsequent packaging sealing performance of the packaging bag are seriously affected. Therefore, how to provide a side inserting device capable of effectively overcoming the resilience of the side inserting and ensuring the flattening and shaping of the folding edge, thereby improving the yield of the packaging bag becomes a technical problem to be solved in the field.
