Automatic test system and method for gas permeability based on artificial intelligence

Abstract

The invention discloses to an automatic test system and method for gas permeability based on artificial intelligence. The upper test chamber and the lower test chamber of the system are both of hollowstructure; a constant-temperature water bath device communicates with an internal circulation pipeline to control the temperature; a differential sensor communicates with the upper test chamber; a lower chamber vacuum sensor communicates with a lower test chamber; a temperature and humidity sensor acquires temperature and humidity; a test gas source communicates with a gas path of the upper testchamber and is provided a first on-off valve; a branch exhausting pipeline communicating with the gas path of the upper test chamber is provided a second on-off valve; a vacuum pump is in communication with the gas paths of both the upper test chamber and the lower test chamber; and a test terminal controls the on-off valves to collect the data acquired by the sensor. The test system of the invention can automatically complete tests without manual intervention, and is accurate in measurement result, high in test efficiency and reduced in test cost.

Description

technical field [0001] The present disclosure relates to the technical field of packaging material testing equipment, in particular to an artificial intelligence-based automatic gas transmission rate testing system and method. Background technique [0002] Plastic packaging is widely used in various fields of food and drug packaging, and the barrier property of packaging materials is a key factor for product quality assurance. The so-called barrier property usually refers to the barrier ability of packaging materials to oxygen and water vapor. The stronger the barrier ability, the less likely it is for oxygen and water vapor in the air to enter the package, and naturally it will not affect the contents inside the package. , Packaging materials with strong barrier ability are usually called high barrier materials, but they are called low barrier materials. The barrier ability of packaging materials to oxygen and water vapor is one of the key factors in the shelf life of prod...
