Description

TECHNICAL FIELD

[0001] The utility model relates to packing technical field more specifically, the utility model relates to a kind of vacuum packing device. BACKGROUND

[0002] Vacuum packaging, also known as "reduced pressure packaging", is mainly to extract all the air inside the plastic bag, forming an oxygen-free or low-oxygen state, and then packaging. This vacuum packaging method is suitable for packaging various non-fresh food, such as marinated food, snacks, cooked products, bean products, preserved fruits, etc. Normally, fresh food cannot be vacuum packaged, as it is mainly concerned that the food may develop some physiological diseases under a high-oxygen deficiency state, which may be counterproductive and result in shorter storage time. Currently, the vacuum packaging process mainly uses vacuum extraction equipment to achieve negative pressure extraction for packaging bags containing products.

[0003] The current method of vacuum extraction for packaging bags is to insert a vacuum tube into the bag to achieve negative pressure extraction with the help of a vacuum pump. For larger packaging bags, the vacuum extraction efficiency is low. In order to improve the sealing performance of the vacuum tube inserted into the packaging bag, the bag structure needs to be manually pinched tightly on the vacuum tube, which increases the burden of manual packaging. At the same time, when the vacuum tube is extracted from the bag, if the bag opening is not closed in time, the vacuum extraction effect will be reduced.
