Abstract

The invention discloses an oxygen barrier property testing device for packaging barrier film research and development, which comprises a bottom plate, supporting legs are fixedly connected to four corners of the bottom of the bottom plate, a film body covers a circular groove II, and a cover plate is hinged to the bottom plate through a hinge seat and is hung in a connecting groove in one end wall of the bottom plate through a hook body; the cover plate, the bottom plate and the pressing plate which are hung are arranged in the first circular groove, the first circular groove and the second circular groove are vacuumized through the vacuum pumps on the two sides, the pressure inside the first circular groove and the second circular groove is observed through the first pressure gauge and the second pressure gauge, and the overload slip characteristic of the torsimeter is utilized to measure the torque of the torsimeter. According to the torsion meter, a first circle is arranged on a pressing plate, the pressing plate compresses air in the first circle under the action of downward pressure, the air serves as a medium to press a film body downwards, after the film body is crushed through compression, overload slipping is generated by the torsion meter, and the final pressure can be observed from a display screen through the torsion meter after overload slipping is generated. Therefore, the gas barrier property of the membrane body can be tested to be maximized according to the passing pressure of the membrane body.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to an oxygen barrier property testing device used for the research and development of packaging barrier films. Background technique [0002] Film packaging is widely used in packaging fields such as food and medicine. Barrier property is an important indicator of the performance of packaging materials, usually referring to the barrier ability of films to air and water vapor. Most of the existing test devices for testing the gas barrier properties of thin films use hand-wheel manual compression. The upper and lower chambers of the test device for testing the gas barrier properties of thin films are compressed by rotating the hand wheel by hand. Although the structure is simple, the operation is time-consuming and labor-intensive. [0003] In this regard, the Chinese invention patent with the authorization announcement number CN102252939A discloses a testing device for t...
