A breathability testing device for jacket fabrics

Abstract

The utility model discloses a fabric air permeability testing device for a jacket, comprising a bracket, a fixing plate fixedly connected to the top of the bracket, a second displacement groove penetrating the surface of the fixing plate, a displacement plate slidably connected to the inside of the bracket, a first displacement groove penetrating the surface of the displacement plate, and a displacement rod slidably connected to the inside of the first displacement groove and the second displacement groove. The utility model solves the problem that when traditional testing equipment tests fabrics, wrinkles may appear on the fabrics when they are fixed because the material of the fabrics is soft. The wrinkles may affect the sealing between the fabrics and the testing equipment, thereby affecting the accuracy of the air tightness test. At this time, the fabrics need to be smoothed manually, which will consume extra time and labor costs. Especially in the case of a large number of tests, manual processing will increase the time cost of the entire testing process.

At this time, the rubber pad 12 contacts the outside of the fabric, and then the position of the fabric is preliminarily fixed to avoid the problem of fabric detachment during detection, thereby increasing the practicality of the device. Next, when smoothing the wrinkles on the surface of the fabric, the displacement component is started to drive the two cross plates 13 to move in opposite directions and increase the friction between the fabric and the rubber pad 12, thereby driving the two sides of the fabric to stretch, so that the wrinkles in the middle of the fabric can be flattened, and then the wrinkles will affect the sealing between the fabric and the detection equipment, thereby avoiding the problem that the accuracy of the airtightness detection is affected, thereby increasing the detection efficiency of the device. Finally, the bellows 7 is started and air is blown to the fabric through its vent. Then, the air pressure detector 6 is driven to approach the fabric by starting the movable rod of the electric telescopic rod 10 to perform an airtightness detection operation.

Then the displacement plate 9 moves to drive the limit block 2 to slide inside the limit groove 3, thereby avoiding the problem of displacement of the displacement plate 9. Then the displacement plate 9 moves to drive the displacement rod 11 to move downward and drive the rubber pad 12 under the cross plate 13 to avoid conflict with the fabric, thereby completing the fixation.
