Abstract

The invention discloses a sealing bag-expanding method suitable for a vacuum bagging machine, and relates to the technical field of packaging. According to the sealing bag-expanding method, one or twobag-expanding rods are arranged, one ends of the bag-expanding rods are connected to a sealing shaft, and the other ends of the bag-expanding rods are connected to bag clamping assemblies of a clamping mechanism; the sealing shaft extends out to drive a sealing block to move towards a packaging bag so as to make the sealing action, in the making process of the sealing action, the sealing shaft drives one set of bag clamping assemblies to move towards the outer side in the length direction of the sealing block or drives the two sets of bag clamping assemblies to move in a mode of relatively getting away from each other through the bag-expanding rods, and thus the bag-expanding action is conducted; and when the sealing block makes contact with a sealing seat in a vacuum cavity to seal a bagopening of the packaging bag, the bag clamping assemblies expand the packaging bag. According to the sealing bag-expanding method, the action of pulling and expanding the packaging bag can be achieved while the sealing action is made, thus the packaging bag is in a flat expanded state when sealed, and the problem of folding of the packaging bag subjected to vacuumizing sealing by an existing vacuum bagging machine is solved.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a method for sealing and expanding bags suitable for a vacuum bagging machine. Background technique [0002] In the food industry, food packaging is an indispensable link. With the increasingly fierce market competition, the requirements for food packaging technology are also increasing. The protection status of food and other aspects have been continuously improved, and the use of computers to control packaging technology and packaging economic activities has also become a common feature of modern packaging development. Full-sealing technologies such as resealable packaging, air-filled packaging, and flexible packaging are being widely promoted. [0003] The vacuum bagging machine is suitable for vacuum bagging and packaging of tea, stewed products, medicines, cooked food and other materials. First, the materials are put into the packaging bag, and then the packaging bag is s...
