Abstract

The invention discloses an air permeability tester which comprises a tester body, a fixing mechanism is arranged on the upper portion of the tester body, a testing mechanism is arranged on the lower portion of the tester body, a fixing frame of the fixing mechanism is hinged to the rear portion of a testing head mounting rod, and a moving frame penetrating through a working table is hinged to the tail end of the mounting rod. A photoelectric sensor is arranged in the middle of a groove of a Z-shaped support connected to the position, below the working table, of the moving frame, a movable block is hinged to the position, in front of the moving frame, of the working table, and the movable block downwards penetrates through the working table to be connected with an electromagnet. One end, provided with a first photoelectric switch, of a first ventilation pipe of the testing mechanism is upwards communicated with the testing head, the other end of the first ventilation pipe is downwards communicated with the upper part of a turntable, the lower part of the turntable is communicated with an exhaust fan, and an air outlet of the exhaust fan is provided with a silencer. The air permeability tester adopting the above structure is simple to operate, and can realize rapid replacement and identification of the test head and adjustment of the diameter of the test pipeline.

Description

technical field [0001] The invention relates to the technical field of fabric air permeability testers, in particular to an air permeability tester. Background technique [0002] The air permeability tester is an instrument for testing the air permeability of textiles. During the test, the test sample is placed in a channel with a fixed cross-sectional area, and the specific air flow will generate a certain pressure difference on the upper and lower sides of the test sample. The test software can automatically calculate the air flow through the fabric according to the pressure difference cross-sectional area, thereby calculating the fabric. breathability performance. Existing air permeability testers on the market often require manual input of the size of the test head, and the diameter of the measurement pipeline cannot be adjusted. Contents of the invention [0003] The purpose of the present invention is to provide a gas permeability tester, which is easy to operate, ...
