Technical Field

[0001] This utility model relates to the field of fabric breathability testing technology, and in particular to a device for testing the breathability of nylon fabric. Background Technology

[0002] Nylon is a man-made fiber produced by the chemical industry, belonging to the polyamide family of materials.

Nylon possesses good abrasion resistance, tear resistance, and a certain degree of elasticity, while also exhibiting good moisture absorption and breathability.

[0003] The air permeability of nylon is one of the important indicators. Existing testing devices can only test one sample at a time, while in actual testing, multiple samples need to be tested, which greatly reduces the testing efficiency. Utility Model Content

[0008] The material receiving component includes an air inlet pipe, which is fixed inside the detection bracket, and a second docking funnel is provided above the air inlet pipe;

[0009] A rotating motor is fixed inside the air inlet pipe, and several fan blades are fixed on the rotor of the rotating motor.

[0012] As an improvement: a support plate is provided inside the detection bracket, and several through holes are provided on the support plate, through which the air inlet pipe can extend downward;

[0013] A second annular limiting plate is fitted onto the air inlet pipe. Several support columns are vertically upward on the support horizontal plate at a position opposite to the second annular limiting plate. The top of the support columns is fixedly connected to the second annular limiting plate.

[0014] A pressure sensor is provided at the junction of the support column and the second annular limiting plate.

[0015] As an improvement, an air inlet filter is provided inside the air inlet duct, and the air inlet filter is located below the rotating motor.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. Place the fabric to be tested onto the second docking funnel, then stretch both ends of the fabric to reduce wrinkles, start the pressing cylinder to move downwards, press the first docking funnel onto the second docking funnel, start the blower fan to blow upwards, and the first gas flow sensor and the second gas flow sensor detect the gas flow on both sides of the fabric respectively, so as to measure the air permeability of the fabric.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Please refer to Figures 1-2 A device for testing the breathability of nylon fabric includes a testing bracket 1, on which a plurality of testing modules are evenly arranged. Each testing module includes a pressing component and a material-supporting component.

[0026] The pressing component includes several pressing cylinders 2, which are vertically downwardly mounted on the top of the detection bracket 1. A first annular limiting plate 3 is fixed on the piston rod of the pressing cylinder 2, and an air outlet pipe 4 is fixed inside the first annular limiting plate 3. A first docking funnel 5 is provided below the air outlet pipe 4.

[0027] The material receiving component includes an air inlet pipe 6, which is fixed inside the detection bracket 1. A second docking funnel 7 is provided above the air inlet pipe 6. A rotating motor 8 is fixed inside the air inlet pipe 6, and several fan blades 9 are fixed on the rotor of the rotating motor 8. A first gas flow sensor 10 is provided inside the air inlet pipe 6, and a second gas flow sensor 11 is provided inside the air outlet pipe 4. In this embodiment, the fabric to be tested is placed on the second docking funnel 7, and then the two ends of the fabric are stretched to reduce wrinkles. The pressing cylinder 2 is activated to move downward, pressing the first docking funnel 5 onto the second docking funnel 7. The fan blades 9 are activated to blow air upward. The first gas flow sensor 10 and the second gas flow sensor 11 detect the gas flow on both sides of the fabric, respectively, thereby measuring the air permeability of the fabric.

[0028] A first sealing ring 12 is provided at the bottom of the first docking funnel 5, and a second sealing ring 13 is provided at the top of the second docking funnel 7. In this embodiment, the first sealing ring 12 and the second sealing ring 13 can press the fabric between them to prevent gas leakage and reduce detection errors.

[0029] A supporting horizontal plate 14 is provided inside the detection bracket 1. Several through holes 15 are formed on the supporting horizontal plate 14, through which the air inlet pipe 6 can extend downwards. A second annular limiting plate 16 is fitted onto the air inlet pipe 6. Several supporting columns 17 are vertically upwards on the supporting horizontal plate 14 at positions opposite to the second annular limiting plate 16, with the top of the supporting columns 17 fixedly connected to the second annular limiting plate 16. A pressure sensor 18 is provided at the joint between the supporting columns 17 and the second annular limiting plate 16. In this embodiment, the pressure sensor 18 ensures that the fabric is tightly pressed between the first docking funnel 5 and the second docking funnel 7.

[0030] An air inlet filter 19 is provided inside the air inlet duct 6, and the air inlet filter 19 is located below the rotating motor 8. In this embodiment, the air inlet filter 19 can filter out external dust and other substances.

[0031] Working principle: Multiple fabrics to be tested are placed sequentially on the corresponding second docking funnel 7. Then, the two ends of the fabric are stretched to reduce wrinkles. The pressing cylinder 2 is activated to move downward, pressing the first docking funnel 5 onto the second docking funnel 7. The pressure sensor 18 detects the pressure of the first docking funnel 5 on the second docking funnel 7, ensuring that the first docking funnel 5 is pressed onto the second docking funnel 7 with a certain pressure. At this time, the fabric is tightly pressed between the first sealing ring 12 and the second sealing ring 13.

[0032] Then, the blower fan blade 9 is activated to blow air upwards. The air is blown from the air inlet pipe 6 into the air outlet pipe 4. The first gas flow sensor 10 and the second gas flow sensor 11 detect the gas flow on both sides of the fabric, and the fabric's breathability can be obtained.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
