Description

Technical Field

[0001] The utility model relates to the technical field of bag making machines, in particular to a discharging mechanism for a zipper bag making machine. Background Art

[0002] Zipper bags can be divided into ordinary zipper bags, document zipper bags and invisible zipper bags. Zipper bags have a wide range of applications and can be used in various fields such as industrial packaging, daily chemical packaging, food packaging, medicine, hygiene, electronics, aerospace, science and technology, and military industry.

[0003] For example, the discharge mechanism of a bag-making machine, designated by authorization announcement number "CN217597969U," neatly stacks the finished bags through the first bag-collecting unit while allowing users to remove the finished bags from the second bag-collecting unit, resulting in high work efficiency. However, the movable plate moves upward to the same level as the discharge platform, and the finished bags move from the discharge platform to the movable plate. As the number of finished bags increases, the pneumatic assembly drives the movable plate to gradually move downward. The topmost finished bag is always at the same level as the discharge platform, without the obstruction of the bag storage box wall. The finished bags at the top are easily disturbed by airflow, causing them to be blown away, affecting the efficiency of collecting the finished bags. Utility Model Content
