Description

Technical Field

[0001] The utility model relates to the field of packaging machines, in particular to a bag taking mechanism of a packaging machine. Background Art

[0002] Bag retrieval by a packaging machine is an important part of the packaging process. Its main purpose is to accurately take out a bag from the bag library and then send it to the next working position for subsequent operations such as filling and sealing. In order to ensure the smooth progress of the bag retrieval process and avoid taking out multiple bags or not being able to take out a bag, packaging machine designers usually use a series of mechanisms and engineering technologies to ensure the stability and accuracy of bag retrieval.

[0003] The commonly used bag taking mechanism is a suction cup, which is used to suck up the packaging bag and then pass it to the next sealing mechanism. However, when the current bag taking mechanism is actually used, the positions of the suction cups are fixed, so it is difficult to adapt to packaging bags of different sizes, resulting in a reduction in the application range of the packaging machine.
