Packaging device capable of automatically detecting packaging sealing performance

Abstract

The invention relates to the technical field of package sealing performance detection, in particular to a packaging device capable of automatically detecting packaging sealing performance, which comprises a support frame. The support frame comprises two fixed blocks, a sliding rod is fixedly connected between two ends of the two fixed blocks, and support legs are fixedly connected to the bottom surfaces of two ends of the two fixed blocks, and a connecting rod is fixedly connected between the middle parts of the two support legs. According to the device, the [-shaped handle is pushed leftwardsto enable the limiting plate to drive the air blowing pipe to move between the two L-shaped clamping plates, the two sliding blocks slide relatively along the sliding rods, and the pressure sensors on the inner side walls and the inner top walls of the two L-shaped clamping plates are attached to the outer side of a packaging bag filled with air; and if the reading of the pressure sensor is stable, the sealing performance of the packaging bag is good, so that the packaging bag is prevented from being wetted by water when the sealing performance of the packaging bag is detected by water to cause pollution and damage.

Description

technical field [0001] The invention relates to the technical field of packaging airtightness detection, in particular to a packaging device for automatically detecting the airtightness of packaging. Background technique [0002] Packaging airtightness refers to the characteristics of the packaging bag to prevent other substances from entering or the contents from overflowing.

[0002] Packaging airtightness refers to the characteristics of the packaging bag to prevent other substances from entering or the contents from overflowing. At present, there are many types of packaging bags used by people. In the production process of packaging bags, due to many production links, heat sealing leaks may occur. Sealing, pressing through, or cracks and micropores in the material itself, forming small holes or weak points connecting the inside and outside, resulting in differences in sealing performance, but it is difficult to check on site. As time goes by, leakage or The problem of moisture deterioration of materials caused by lax sealing;

[0003] The traditional method for testing the airtightness of flexible packaging is mainly the underwater decompression method (also called vacuum method or bubble method), that is, the packaging fixture to be tested is immersed in the water in the transparent container, and the transparent container is sealed and connected to a vacuum generator. Vacuum it with a low-power microscope or naked eyes to judge whether there are bubbles in the packaging bag to judge its tightness. The detection accuracy is low, and the water will soak the packaging bag during the detection process, causing pollution and damage to the packaging bag, thus Affects the practicability of the packaging device for automatic detection of packaging tightness
