Description

Disc nut automatic packing device

Technical Field

The utility model relates to a food automated production assembly line technical field, concretely relates to disc nut automatic packing device.

Background

Leisure foods (leisurefood) are also a kind of fast-consumption products, and are foods eaten by people during leisure and rest, such as melon seeds, peanuts, preserved plums, biscuits and the like. With the increasing living conditions. The demand of China for such leisure food is continuously increasing.

For some snack foods, the consumer cannot consume the food all at once. In order to prevent food from deteriorating or getting damp, people choose to re-package food bags, and zipper type packaging bags are packaging bags capable of being simply and repeatedly packaged. For food manufacturers, the zipper-type food bag for filling food comprises three steps: opening the bag, filling and closing the bag. When the zipper type packaging bag leaves a factory, in order to save space, the packaging bag is vacuumized, and the zipper is in a closed state. At present, food manufacturers mostly adopt manual means to carry out three steps of opening, filling, closing and the like, and the food packaging machine is low in efficiency and high in labor cost. There are also automatic bag opening devices, such as CN202038483U and CN200974625Y, which do not include two steps of filling and closing bags, and have complicated structure and large floor space.

Therefore, there is a need in the art for an automatic packaging device for zipper-type packaging bags that has a small footprint and a high degree of automation.
