Description

Technical Field

[0001] This invention relates to the field of fabric testing technology, and more specifically, to a device for testing the breathability of quick-drying fabrics. Background Technology

[0002] Fabric breathability is an important indicator of fabric quality. It directly affects the comfort of using the fabric. If the breathability is too low, the heat and moisture generated by the wearer will not be easily expelled, making the wearer feel stuffy and uncomfortable. Therefore, fabric breathability testing is particularly important in the fabric production and processing process, and breathability testing devices are widely used in the field of fabric testing technology.

[0003] Existing fabric breathability testing devices are diverse. For example, Chinese invention patent CN112444476A discloses a fabric breathability testing device, which includes a testing chamber, a fan, a take-up roller, and an unwind roller. The testing chamber has an inlet and an outlet on its left and right sides, respectively. An unwind roller is located on the inlet side, and a take-up roller is located on the outlet side. A test tube is located on the top of the testing chamber, and the lower end of the test tube is connected to the interior of the testing chamber. The test tube has a first through groove, and a support is located at the bottom of the first through groove. The test tube is equipped with a sphere and a second through groove located outside the first through groove. A marking assembly is installed inside the second through groove. The marking assembly includes an imprint block, a pull rod, a spring, and a first limiting block. The imprint block is movably positioned at the bottom of the second through groove via the pull rod. Dye is applied to the lower surface of the imprint block. The upper end of the pull rod extends from the upper end of the second through groove. During the test, the airflow from the fan enters the test tube through the dye, causing the sphere to move upward. The permeability of the dye is determined by observing the amount of upward displacement of the sphere.

[0004] Although the aforementioned equipment evaluates the permeability of dyes by observing the upward displacement of the sphere, the accuracy of the test results is poor due to the large error in manually observing the displacement of the sphere.

[0005] To address the aforementioned issues, this invention provides an air permeability testing device for quick-drying fabrics. This device can detect the amount of air passing through the fabric in real time, thereby detecting the fabric's air permeability and ensuring the accuracy of the test results.

[0012] Preferably, in the above-mentioned air permeability detection device, when the servo motor drives the detection box to rotate in the opposite direction, the connecting shaft and the one-way bearing rotate synchronously with the detection box, and the bevel gear I and bevel gear II remain relatively stationary, thereby making the rotating disk stationary relative to the detection box.

[0014] Preferably, the above-mentioned air permeability testing device further includes a support frame, on which an adjustment component is installed. The fixing frame of the testing unit is installed on the adjustment component. The adjustment component can drive the testing unit to move, so that the nozzle on the testing unit on one side of the fabric clamping mechanism abuts against the surface of the quick-drying fabric, and the air volume detection sensor on the testing unit on the other side of the fabric clamping mechanism abuts against the surface of the quick-drying fabric.

[0015] Preferably, in the above-mentioned air permeability detection device, the adjustment component includes a fixed rail mounted on a support frame and a threaded rod mounted in the fixed rail. A slider is threaded onto the threaded rod, and a fixed frame is connected to the slider. One end of the threaded rod is connected to a drive motor.

The device includes a testing unit, which contains a testing box. A rotating disk is installed at the testing port of the testing box, and a nozzle is installed on the rotating disk.

Therefore, by adjusting the position of the nozzle, the air permeability of different positions of the quick-drying fabric can be tested, further ensuring the accuracy of the air permeability test results of the quick-drying fabric.

Detailed Implementation

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0025] like Figure 1 ,Figure 2 as well as Figure 3 As shown, this is a structural schematic diagram of the air permeability testing device in this embodiment. The air permeability testing device in this embodiment tests the air permeability of quick-drying fabric. The air permeability testing device in this embodiment includes a support frame 100 and an adjustment component 101 disposed on the support frame 100. In this embodiment, detection units 200 are disposed opposite each other on the adjustment component 101. The adjustment component 101 is used to adjust the distance between the two detection units 200. In addition, in this embodiment, the support frame 100 is also provided with a mounting groove 100a. A fabric clamping mechanism is installed in the mounting groove 100a. The quick-drying fabric is fixed in the fabric clamping mechanism. In this embodiment, the detection units 200 are located on both sides of the fabric clamping mechanism. The air permeability of the quick-drying fabric in the fabric clamping mechanism is tested by the detection units 200 to achieve the purpose of testing the air permeability of the fabric.

[0026] like Figures 3-6 As shown, in this embodiment, the support frame 100 has an L-shaped structure and is composed of a vertical fixing plate and a horizontal fixing plate. The vertical fixing plate and the horizontal fixing plate are fixedly connected to form an L-shaped structure. The mounting groove 100a is located on the horizontal fixing plate, and the adjustment component 101 is located on the vertical fixing plate. In this embodiment, the detection unit 200 is mounted on the adjustment component 101. The position of the detection unit 200 can be adjusted by the adjustment component 101 so that the detection unit 200 is closer to or further away from the fabric clamping mechanism, so as to facilitate the air permeability test of the fabric.

[0027] like Figure 6 As shown, the adjustment component 101 in this embodiment includes a fixed track 101a fixedly mounted on a vertical fixed plate, and a threaded rod 101b is installed in the fixed track 101a. A slider 101c is threadedly connected to the threaded rod 101b. In this embodiment, the detection unit 200 is mounted on the slider 101c, and a drive motor is connected to the threaded rod 101b. The operation of the drive motor can drive the threaded rod 101b to rotate, which in turn can drive the slider 101c to move along the length direction of the threaded rod 101b, which in turn can drive the detection unit 200 to move along the length direction of the threaded rod 101b. This allows the detection unit 200 to be driven closer to or further away from the fabric clamping mechanism, so as to facilitate the air permeability test of the quick-drying fabric in the fabric clamping mechanism.

[0028] like Figure 7As shown, in this embodiment, the detection unit 200 includes a fixed frame 201. The end of the fixed frame 201 is a U-shaped frame structure, and the fixed frame 201 is fixedly connected to the slider 101c on the threaded rod 101b. In this embodiment, the detection unit 200 also includes a detection box 202 installed at the end of the fixed frame 201. When the threaded rod 101b rotates, it drives the slider 101c to move, which in turn drives the fixed frame 201 and the detection box 202 to move, so that the detection box 202 can move closer to or further away from the fabric clamping mechanism.

[0029] like Figure 5 As shown, in this embodiment, in order to ensure the stability and smoothness of the movement of the fixed frame 201, a fixing groove is provided on both sides of the adjustment component 101 on the vertical fixing plate. In this embodiment, the end of the fixed frame 201 is slidably assembled in the fixing groove. Therefore, when the threaded rod 101b rotates, it drives the slider 101c to move, which in turn drives the fixed frame 201 to move. When the fixed frame 201 moves, it moves along the length direction of the fixing groove, thereby ensuring the smoothness and stability of the movement of the fixed frame 201.

[0030] like Figure 7 as well as Figure 8 As shown, in this embodiment, a servo motor is connected to the end of the fixing frame 201. The power end of the servo motor is connected to the detection box 202. The operation of the servo motor can drive the detection box 202 to rotate and control the rotation angle of the detection box 202. In this embodiment, a detection port 202a is provided on one side of the detection box 202, and a rotating disk 203 is installed in the detection port 202a. A nozzle 204 is provided on the rotating disk 203. In addition, an air volume detection sensor 205 is provided on the other side of the detection box 202. When it is necessary to test the air permeability of the quick-drying fabric in the fabric clamping mechanism, in this embodiment, the servo motor drives the detection box 202 on one side of the fabric clamping mechanism to rotate, so that the air volume detection sensor 205 can be used to detect the air permeability of the fabric. The nozzle 204 on the testing box 202 faces the fabric clamping mechanism. The servo motor on the other side of the fabric clamping mechanism rotates the testing box 202, causing the air volume detection sensor 205 on the testing box 202 to face the fabric clamping mechanism. Then, the adjusting component 101 drives the detection units 200 on both sides of the fabric clamping mechanism to move, so that the nozzle 204 on one side of the fabric clamping mechanism comes into contact with the surface of the quick-drying fabric, and the air volume detection sensor 205 on the other side of the fabric clamping mechanism comes into contact with the surface of the quick-drying fabric. Then, the nozzle 204 sprays gas through the quick-drying fabric, and the air volume detection sensor 205 on the other side of the quick-drying fabric is used to detect the amount of air received, thereby obtaining the air permeability result of the quick-drying fabric.

[0031] In this embodiment, the nozzle 204 on the detection box 202 on one side of the fabric clamping mechanism comes into contact with the surface of the quick-drying fabric, and the air volume detection sensor 205 on the detection box 202 on the other side comes into contact with the surface of the quick-drying fabric. Then the nozzle 204 sprays out gas, and the air volume detection sensor 205 receives the gas to determine the air permeability of the quick-drying fabric.

[0032] In this embodiment, to facilitate the testing of the air permeability of the quick-drying fabric at different locations, such as... Figure 8 as well as Figure 9 As shown, in this embodiment, a rotating shaft 204a is connected inside the detection box 202. The rotating shaft 204a is connected to the rotating disk 203 inside the detection port 202a. In this embodiment, a connecting shaft is also installed inside the detection box 202. The connecting shaft extends to the outside of the bottom of the detection box 202, and the end of the connecting shaft is connected to the fixing frame 201 through a one-way bearing 206. In this embodiment, the one-way bearing 206 can only move in one direction. For example, if the one-way bearing 206 can rotate in the clockwise direction, it cannot rotate in the counterclockwise direction.

[0033] like Figure 9 As shown, in this embodiment, a bevel gear I 204b is connected to the rotating shaft 204a, and a bevel gear II 204c is connected to the connecting shaft. The bevel gear I 204b and the bevel gear II 204c mesh. In addition, the end of the rotating shaft 204a is connected to a rotating shaft interface 204d, which extends to the outside of the detection box 202 and connects to the air pipe. In this embodiment, the rotating shaft 204a is a hollow shaft structure. Gas enters the hollow rotating shaft 204a through the air pipe and the rotating interface 204d, and then enters the rotating disk 203 and is ejected through the nozzle 204.

[0034] When the detection position needs to be adjusted, in this embodiment, the servo motor drives the detection box 202 to rotate. At this time, the one-way bearing 206 and the connecting shaft cannot rotate. When the detection box 202 rotates, it drives the rotating shaft 204a to rotate. The bevel gear I 204b on the rotating shaft 204a meshes with the bevel gear II 204c on the connecting shaft. Therefore, the rotating shaft 204a can be rotated by the meshing of bevel gear I 204b and bevel gear II 204c, which in turn drives the rotating disk 203 to rotate within the detection port 202a, thereby causing the nozzle 204 to rotate and change its position. After the position of the nozzle 204 is adjusted, the servo motor drives the detection box 202 to rotate in reverse. The nozzle 204 is rotated until it is directly facing the fabric clamping mechanism. At this time, the one-way bearing 206 rotates synchronously with the connecting shaft. Therefore, the bevel gear I 204b and bevel gear II 204c are relatively stationary, and the position of the rotating disk 203 does not change. When the nozzle 204 of the detection box 202 is directly facing the fabric clamping mechanism, the adjusting component 101 drives the detection unit 200 to move until the nozzle 204 touches the surface of the quick-drying fabric on the fabric clamping mechanism. Then, the air volume detection sensor 205 on the other side of the detection unit 200 touches the surface of the quick-drying fabric. Gas is sprayed out through the nozzle 204 and the air volume detection sensor 205 detects the received air volume, which is used to detect the air permeability of the quick-drying fabric.

[0035] Additionally, it should be noted that the detection units 200 in this embodiment are arranged opposite to each other on both sides of the fabric clamping mechanism. When it is necessary to detect the air permeability of the other side of the fabric, the nozzle 204 in the detection unit 200 on the other side of the fabric comes into contact with the fabric surface, and the air volume detection sensor 205 on the opposite side is used to detect the air permeability of the other side of the fabric.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
