Description

Wrapping bag material collecting device Technical Field The utility model relates to the technical field of packaging machinery, in particular to a material collecting device for automatically and regularly stacking cut flexible packaging bags. Background In the process of producing flexible packages, it is often necessary to slit the flexible packages on a bag making machine to form individual packages. In the traditional production mode, after the cut packaging bags are output along with a conveying belt, the packaging bags are stacked together in random and scattered states due to soft self-texture and lack of shaping support. This irregular stacking approach results in the need for subsequent steps to be handled and aligned by special personnel, which not only greatly increases labor costs, but also limits the speed of circulation of the overall production line. Along with the upgrading of bag making equipment technology, production efficiency is obviously improved, and the existing manual or semi-automatic material receiving mode becomes a bottleneck for restricting capacity improvement, so that the labor intensity of workers is extremely high, and the packaging bag is easily scratched or polluted due to fatigue, so that the requirements of modern high-speed production are difficult to meet.
