Description

Technical Field

[0001] This utility model belongs to the field of textile engineering technology, specifically a device for testing the air permeability of textile fabrics. Background Technology

[0002] The history of textiles can be traced back thousands of years. Ancient humans used natural fibers to hand-weave and create the earliest clothing and decorations, such as cotton, silk, wool, and hemp. These materials have good breathability and comfort and are widely used in clothing and home textiles. With the advancement of technology, breathability testing has become an important indicator for evaluating fabric performance, especially in the fields of sports, outdoor and medical applications.

[0003] The principle of textile fabric air permeability testing equipment mainly involves two aspects: pressure difference measurement and gas flow. Through precise pressure difference measurement and gas flow application, textile fabric air permeability testing equipment can efficiently detect textile fabrics that meet the requirements, providing strong support for textile fabric testing.

[0004] Existing testing equipment mostly involves placing the fabric to be tested on a testing platform and then starting the testing equipment to test the fabric. When testing fabric in this way, the fabric will move when the airflow or pressure changes, which will change the airflow path in the testing area, thus affecting the measurement of gas flow and producing inaccurate results. Therefore, in order to address the above problems, a new air permeability testing device for textile fabrics is proposed. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, most existing testing equipment involves placing the fabric to be tested on a testing platform and then starting the testing equipment to test the fabric. When testing fabric in this way, the fabric will move when the airflow or pressure changes, which will change the airflow path in the testing area, thus affecting the measurement of gas flow and producing inaccurate results. This utility model proposes a test device for the air permeability of textile fabrics.

[0006] The technical solution adopted by this utility model to solve its technical problem is a textile fabric air permeability testing device, including a base plate, with bases fixedly installed at the four diagonal corners of the top of the base plate, and connecting blocks fixedly installed on the top of the bases. The interiors of the bases and connecting blocks are hollow. Multiple support plates are fixedly installed on the top of the base plate, and electric push rods are fixedly installed on the top of the support plates. A moving rod is fixedly installed at the output end of the electric push rod. One side of the moving rod is serrated. A gear is meshed with the interior of the base at one end of the moving rod. The bottom of the gear is rotatably installed on the bottom inner wall of the base. A rotating rod is fixedly installed on the top of the gear. A connecting plate is fixedly installed with the interior of the connecting block at one end of the rotating rod. A pressing block is fixedly installed at the bottom of one end of the connecting plate. A limit groove is formed on the side of one end of the rotating rod. A pressing block is installed inside the connecting block. A limiting rod is provided, with one end passing through the interior of the connecting block and tightly fitting against the interior of the limiting groove. A detection platform is located below the multiple pressing blocks, with its bottom fixedly installed at the top center of the base plate. Tensioning components are located at the center of each of the four ends of the base plate. These components stretch the fabric to be tested at all four ends. Then, an electric push rod drives a moving rod and gear to rotate. The serrations on the outer side of the moving rod and the gear are inclined, preventing the gear from sliding downwards when the moving rod drives the gear to rotate. When the gear moves, the rotating rod drives the limiting rod to move up and down. This up-and-down movement of the limiting rod fixes the pressing blocks to the fabric to be tested. Fixing the fabric prevents airflow from causing it to shift during the testing process, resulting in more accurate final test data.

[0007] Preferably, brackets are fixedly installed at all four ends of the top of the base plate, a top plate is fixedly installed on the outside of one end of each bracket, and the main body of the testing equipment is fixedly installed at the bottom center of the top plate. A display screen is installed on the outside of the main body of the testing equipment, and a testing pressure head is installed inside the main body of the testing equipment. The main body of the testing equipment drives the internal testing pressure head to test the air permeability of the fabric to be tested. After the test is completed, the air permeability data of the fabric will be displayed on the display screen, which allows for a more convenient understanding of the test results.

[0008] Preferably, the stretching assembly includes a fixing block, the bottom of which is fixedly mounted on the top of the base plate. A connecting rod is fixedly mounted inside the fixing block, and a telescopic cylinder is rotatably mounted outside the connecting rod. A spring is fixedly mounted inside the telescopic cylinder, and a fixing plate is fixedly mounted outside one end of the telescopic cylinder. A clamp is fixedly mounted outside one side of the fixing plate. The clamp is extended and retracted by the spring inside the telescopic cylinder. When the clamp extends and retracts, it causes the clamped fabric to contract, thereby stretching the four ends of the fabric to be tested and preventing wrinkles from occurring during air permeability testing, which could lead to testing errors.

[0009] Preferably, a detection slot is provided at the top center of the detection platform, and a sealing ring is fixedly installed on the inner wall side of the detection slot. The outer side of the sealing ring is tightly attached to the outer side of the detection head. When the detection head is connected to the detection slot to detect the fabric, the gap between the detection slot and the detection head can be reduced by the sealing ring on the inner wall of the detection slot, thereby improving the sealing effect and preventing errors during detection.

[0010] Preferably, the top of the testing platform has mounting slots at all four diagonal ends, and the outer part of the pressing block is located inside the mounting slot. When it is necessary to fix the fabric to be tested, the fabric to be tested can be fixed by connecting the pressing block and the mounting slot, making the part to be tested tighter and increasing the accuracy of the test.

[0011] Preferably, rubber pads are fixedly installed on the bottom of each of the plurality of pressing blocks. When the pressing blocks are in contact with the mounting groove, the rubber pads at the bottom of the pressing blocks can increase the friction between the fabric to be tested and the mounting groove, thereby achieving a more stable fixation of the fabric to be tested.

[0012] The advantages of this utility model are:

[0013] This invention addresses the problem of inaccurate gas flow measurements when using a breathability testing device to test the internal structure of textile fabrics. An electric push rod drives a moving rod and gears to rotate. As the gears move, the rotating rod moves a limiting rod up and down, which in turn moves a pressing block to fix the fabric under test. This solves the problem that most existing testing methods involve placing the fabric on a testing platform and then starting the device. In this method, the fabric moves with changes in airflow or pressure, altering the airflow path in the testing area and affecting gas flow measurement. By fixing the fabric under test, the airflow prevents it from shifting during testing, resulting in more accurate final test data. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5As shown, an air permeability testing device for textile fabrics includes a base plate 1. Bases 4 are fixedly installed diagonally at each of the four ends of the top of the base plate 1. Connecting blocks 5 are fixedly installed on the top of each base 4. The interiors of both the bases 4 and the connecting blocks 5 are hollow. Multiple support plates 13 are fixedly installed on the top of the base plate 1. Electric push rods 14 are fixedly installed on the top of each support plate 13. A moving rod 6 is fixedly installed at the output end of each electric push rod 14. One side of the moving rod 6 is serrated, and one end of the moving rod 6 passes through the interior of the base 4. A gear 7 is meshed with the base 4. The bottom of the gear 7 is rotatably mounted on the bottom inner wall of the base 4. A rotating rod 8 is fixedly mounted on the top of the gear 7. One end of the rotating rod 8 passes through the inside of the connecting block 5 and is fixedly mounted with a connecting plate 11. A pressing block 12 is fixedly mounted on the bottom of one end of the connecting plate 11. A limiting groove 9 is formed on the side of one end of the rotating rod 8. A limiting rod 10 is installed inside the connecting block 5. One end of the limiting rod 10 passes through the inside of the connecting block 5 and is tightly attached to the inside of the limiting groove 9. Below the multiple pressing blocks 12... A testing platform 15 is provided, with its bottom fixedly installed at the top center of a base plate 1. Tensioning components 22 are provided at the center of each of the four ends of the base plate 1. In operation, most existing testing equipment places the fabric to be tested on a testing table and then starts the testing equipment to test the fabric. However, this method causes the fabric to move due to changes in airflow or pressure, altering the airflow path in the testing area and affecting the gas flow measurement, resulting in inaccurate results. The electric push rod 14 is activated to move the moving rod 6. When the moving rod 6 moves, it drives the gear 7, which meshes with it, to rotate. The serrations on the outer side of the moving rod 6 and the gear 7 are inclined and mesh with each other. When the gear 7 rotates, it drives the rotating rod 8 to rotate. When the rotating rod 8 rotates to a certain angle, it is driven downwards by the limiting rod 10 along the limiting groove 9, causing the rotating rod 8 and gear 7 to move. The downward movement of the rotating rod 8 causes the connecting plate 11 and pressing block 12 to move downwards, thus fixing the fabric to be tested.

[0023] The base plate 1 has four fixed supports 2 at its top. A top plate 3 is fixedly installed on the outside of one end of each support 2. The main body of the testing equipment 16 is fixedly installed at the bottom center of the top plate 3. A display screen 17 is installed on the outside of the main body of the testing equipment 16. A testing pressure head 18 is installed inside the main body of the testing equipment 16. In operation, most existing testing equipment places the fabric to be tested on the testing table and then starts the testing equipment to test the fabric. When testing the fabric in this way, the fabric will move when the airflow or pressure changes, which will change the airflow path in the testing area, thus affecting the measurement of gas flow and producing inaccurate results. The testing equipment 16 starts the testing pressure head 18 to test the fabric. After the test is completed, the real-time data of the test can be displayed on the display screen 17 connected to it.

[0024] The stretching assembly 22 includes a fixing block 23, the bottom of which is fixedly installed on the top of the base plate 1. A connecting rod 25 is fixedly installed inside the fixing block 23, and a telescopic cylinder 24 is rotatably installed outside the connecting rod 25. A spring 26 is fixedly installed inside the telescopic cylinder 24, and a fixing plate 27 is fixedly installed outside one end of the telescopic cylinder 24. A clamp 28 is fixedly installed outside one side of the fixing plate 27. During operation, most existing testing equipment places the fabric to be tested on the testing table and then starts the testing equipment to test the fabric. When testing the fabric in this way, the fabric will move when the airflow or pressure changes, which will change the airflow path in the testing area, thus affecting the measurement of gas flow and producing inaccurate results. When the clamp 28 fixes the fabric to be tested, the spring 26 inside the telescopic cylinder 24 can stretch the fabric to be tested.

[0025] The detection platform 15 has a detection slot 19 at the top center. A sealing ring 20 is fixedly installed on the inner wall of the detection slot 19, and the outer side of the sealing ring 20 is tightly attached to the outer side of the detection head 18. During operation, most existing detection equipment places the fabric to be tested on the detection table and then starts the detection equipment to test the fabric. When testing the fabric in this way, the fabric will move when the airflow or pressure changes, which will change the airflow path in the test area, thus affecting the measurement of gas flow and producing inaccurate results. When the detection head 18 is connected to the detection slot 19, the sealing ring 20 can improve the sealing of the connection.

[0026] The top of the testing platform 15 has four diagonally opposite mounting slots 21, and the pressing block 12 is located inside the mounting slot 21. During operation, most existing testing equipment places the fabric to be tested on the testing table and then starts the testing equipment to test the fabric. When testing the fabric in this way, the fabric will move when the airflow or pressure changes, which will change the airflow path in the test area, thus affecting the measurement of gas flow and producing inaccurate results. By connecting the mounting slot 21 inside the testing platform 15 with the pressing block 12, the fabric to be tested can be pressed into the mounting slot 21.

[0027] Rubber pads are fixedly installed on the bottom of each of the pressing blocks 12. During operation, most existing testing equipment places the fabric to be tested on the testing table and then starts the testing equipment to test the fabric. When testing the fabric in this way, the fabric will move when the airflow or pressure changes, which will change the airflow path in the test area, thereby affecting the measurement of gas flow and producing inaccurate results. The rubber pads set at the bottom of the pressing blocks 12 can make the pressing point more compact when pressing the fabric.

[0028] Working principle: During the air permeability testing of textile fabrics, when using an air permeability testing device to test the internal structure of the fabric, the four ends of the fabric to be tested are fixed with clamps 28. When the fabric is fixed by clamps 28, the telescopic cylinder 24 connected to clamps 28 and the spring 26 inside it retracts. When the telescopic cylinder 24 retracts, it stretches the fixed fabric, preventing wrinkles during fixing. Then, the electric push rod 14 is activated to move the moving rod 6. When the moving rod 6 moves, it drives the gear 7 meshing with it to rotate. The serrations on the outer side of the moving rod 6 and the gear 7 are interlocked. All are inclined and meshed with each other. When gear 7 rotates, it drives rotating rod 8 to rotate. When rotating rod 8 rotates to a certain angle, it is driven by limiting rod 10 along limiting groove 9 to move rotating rod 8 and gear 7 downward. When rotating rod 8 moves downward, it drives connecting plate 11 and pressing block 12 to move downward. When pressing block 12 moves downward, it connects with mounting groove 21 opened inside detection platform 15. When pressing block 12 and mounting groove 21 are connected, the stretched fabric is fixed. Then, the detection pressure head 18 extends from the main body of detection equipment 16 and connects with detection groove 19 to achieve the effect of detecting the air permeability of the fabric.
