AI Technical Summary

Technical Problem

Existing vacuum packaging machines often result in wrinkles at the opening of packaging bags and require complex structures with reciprocating support mechanisms, necessitating regular maintenance.

Method used

A vacuum packaging machine equipped with a simple pulling mechanism that symmetrically attaches to both sides of a rail, allowing for horizontal tension on the packaging bag opening to prevent wrinkles, without the need for a reciprocating support mechanism.

Benefits of technology

The solution effectively eliminates wrinkles at the opening of packaging bags during the vacuum packaging process, ensuring a neat seal and reducing maintenance requirements due to its simpler structure.

Abstract

To provide a vacuum packaging machine capable of neatly sealing a packaging bag with wrinkles prevented from occurring at an opening thereof by pulling both ends of the opening of the packaging bag in an extending direction by a simple tensioning mechanism.SOLUTION: A vacuum packaging machine 10 for vacuum-packaging an object packaged by reducing the pressure within a chamber in a state of accommodating a packaging bag receiving an object packaged and sealing an opening of the packaging bag in a closed state after removing air from the packaging bag, comprises a tensioning mechanism 100 that is positioned outside a lower sealing block 50 for sealing and attached with puller units symmetrically left and right on both sides of a rail, so that the opening of the packaging bag can be pulled by the puller units in a horizontal direction of the rail without loosening.SELECTED DRAWING: Figure 1
