A new type of micro air permeability tester

Abstract

The invention provides a novel micro air permeability tester, and mainly relates to the field of material detection equipment. The novel micro air permeability tester comprises a workbench; an experiment cavity which is divided into an upper cavity and a lower cavity; an oxygen pump; a carrier pump; a gas concentration detection chamber, which is provided with a sensor inside, wherein the sensor is used for detecting oxygen content in output air flow of a second air outlet; a temperature controller located on the bottom surface of the lower cavity; a rotary support which comprises a fixing rodfixed on a test bench and a rotary drum rotatably connected with the fixing rod; a sliding cylinder, which is in sliding connection with a rotary drum; a plurality of carrier arms, which are providedwith elastic claws at one end which is far away from the rotary drum; a sample cartridge; and an industrial personal computer system. The beneficial effects of the present invention are that: according to the novel micro air permeability tester, detection samples can be replaced without manual operation, next round of operation can be automatically completed, so that detection efficiency of the sample is improved.

Description

technical field [0001] The invention mainly relates to the field of material detection equipment, in particular to a novel micro-permeability tester. Background technique [0002] Micro air permeability tester is a device used to measure the barrier effect of packaging materials on gas and other permeable substances. When testing thin plastic packaging materials, it usually ranges from 6 to 26 hours. When packaging is tested, it often takes several days. Due to the short duration of detection of plastic packaging materials with thin thickness, especially the detection time of about 8 hours, multiple tests can be carried out in one day, but the current detection equipment does not support automatic sampling and setting out, and still relies on operation The personnel start the detection process manually, which leads to either a special person on duty in the laboratory, and manually replaces the sample to ensure full use of the equipment and improve work efficiency, but this w...

Due to the short duration of detection of plastic packaging materials with thin thickness, especially the detection time of about 8 hours, multiple tests can be carried out in one day, but the current detection equipment does not support automatic sampling and setting out, and still relies on operation The personnel start the detection process manually, which leads to either a special person on duty in the laboratory, and manually replaces the sample to ensure full use of the equipment and improve work efficiency, but this will consume labor costs; or it can only be used during normal working hours. use, let the equipment complete a round of detection after get off work and then idle, which will lead to inefficiency and inability to make full use of the equipment
