PACKAGING MACHINE FOR FOUR-EDGE SEALED THREE-DIMENSIONAL BAG

The present application discloses a packaging machine for a four-edge sealed three-dimensional bag. The packaging machine is provided with an automatic film supply module at the lower part of a quantitative conveying line, and a punching apparatus cooperates with a three-sealing module for conveying to shape and seal three three-dimensional edges of a three-dimensional bag. By means of the actions above, a coating is introduced to a rear-end bagging conveying line by means of a film guide frame, and at the same time, the rear-end bagging conveying line is docked with the quantitative conveying line. Quantitatively bagged food is introduced into a film, and then the last edge of the film is sealed. After the actions above, the four-edge sealed three-dimensional bag moves to a port sealing module on the rear-end bagging conveying line in a cylindrical unsealed state, and then the bas passes through the port sealing module to hot-melt and seal two ends of the four-edge sealed three-dimensional bag.
