Bag supplying and bag feeding device and method for full-automatic vacuum packaging production line

Abstract

The invention discloses a bag supplying and bag feeding device for a full-automatic vacuum packaging production line. The bag supplying and bag feeding device comprises a bag supplying part and a bagfeeding part; the bag supplying part comprises a machine base and at least one set of bag supplying unit mounted on the machine base, and the bag supplying unit comprises a bag pushing cylinder, a bagpushing plate connected to the bag pushing cylinder, a bag pressing cylinder, a bag pressing plate connected to the bag pressing cylinder and a pair of bag hanging rods. Packaging bags penetrate through the bag hanging rods through handle holes and are limited between the bag pushing plate and the bag pressing plate, the bag pushing plate is driven by the bag pushing cylinder to push the packaging bags on the bag hanging rods to move forward to perform bag feeding, and the bag pressing plate is driven by the bag pressing cylinder to block or leave the front ends of the bag hanging rods to limit the packaging bags on the bag hanging rods or to enable the bag feeding part to take the packaging bags. The bag supplying and bag feeding device for the full-automatic vacuum packaging productionline has the advantages of novel structure, ingenious property, high stability and high precision.

Description

technical field [0001] The invention relates to a bag feeding device and method for a fully automatic vacuum packaging production line. Background technique [0002] In recent years, because the demand of many families for rice has gradually changed from the original large packaging of more than 10Kg to the small bag packaging of less than 10Kg, vacuum packaging has also become the preferred choice of most grain processing enterprises because it can prolong the fresh-keeping period and facilitate stacking, storage and transportation. The mainstream packaging method, most of the packaging bags they use are three-sided sealing, and the handle part is either punched or has a handle buckle; most of the traditional supply bags use bag boxes, because the packaging bags are stacked. It is only suitable for the positioning of bags with uniform thickness, and the bags with handle buckle are easy to move when stacked, so it is difficult to achieve reliable positioning when a little mo...

[0002] In recent years, because the demand of many families for rice has gradually changed from the original large packaging of more than 10Kg to the small bag packaging of less than 10Kg, vacuum packaging has also become the preferred choice of most grain processing enterprises because it can prolong the fresh-keeping period and facilitate stacking, storage and transportation. The mainstream packaging method, most of the packaging bags they use are three-sided sealing, and the handle part is either punched or has a handle buckle; most of the traditional supply bags use bag boxes, because the packaging bags are stacked. It is only suitable for the positioning of bags with uniform thickness, and the bags with handle buckle are easy to move when stacked, so it is difficult to achieve reliable positioning when a little more bags are placed. At the same time, most of the bags are conveyed by belts Positioning method, this method has a large degree of freedom and is greatly affected by the shape of the packaging bag. When the packaging bag is deformed, the positioning of the bag mouth is easy to deviate, which directly causes the instability of the supply bag and the bag, and brings great harm to the subsequent packaging. deadly impact
