[0002] In the packaging of food seasonings, the packaging is mostly in the form of a combination set, with other independent small material bags further packaged in a pre-packaged outer bag. If the pre-packaged outer bag is over-evacuated, it may cause the product in the set to bulge; if the pre-packaged outer bag is not evacuated or the air is not evacuated sufficiently, it often causes the heat seal to deviate and the volume to be uneven, resulting in unstable stacking shape during palletizing and leaking of seals; if manual exhaust is used, the efficiency is too low, and there is a risk of microbial contamination, and there is no standard for the exhaust volume. Therefore, in response to the above problems, it is urgent to create a device for automatically exhausting air from packaging bags to ensure the exhaust volume standard on the production line and promote the smooth and effective operation of subsequent steps.
