Description

Technical Field

[0001] This utility model relates to the field of textile fabric technology, specifically to a textile fabric air permeability testing device. Background Technology

[0002] Textiles are an indispensable part of life. Different garments use different fabrics, making breathability a crucial factor. Therefore, it's necessary to assess the breathability of fabrics. However, textile fabric breathability testing devices are specialized equipment used to quantify the air permeability of materials. Conventional testing devices have a simple structure and lack the ability to clamp and limit the fabric, causing fabric displacement and resulting in testing errors. Furthermore, the equipment usually needs to be manually handled after testing, which can pose safety hazards to workers. Therefore, a textile fabric breathability testing device has been designed to address these issues.

[0003] A breathability testing device, authorized by CN220603255U, includes a base, a test container, and an air delivery assembly. The test container is connected to the base, and the outlet of the air delivery assembly points inward toward the interior of the test container. A clamping assembly for holding a breast pad under test is detachably installed on the inner wall of the test container. The test container contains a transparent liquid, and its top is open. The breast pad under test is placed inside the test container and secured using the clamping assembly. The outlet of the air delivery assembly points inward toward the interior of the test container and is aligned with the breast pad under test, with a certain distance between the outlet and the breast pad. The permeability of the gas is observed to infer the breathability of the breast pad.

[0004] Based on existing solutions and actual production and processing applications, current textile fabric air permeability testing devices still have some problems: First, existing textile fabric air permeability testing devices lack a fabric clamping mechanism, causing fabric displacement during testing and resulting in errors. Second, textile fabric air permeability testing devices cannot adjust the clamping distance of the clamping equipment according to the fabric length. Finally, textile fabric air permeability testing devices lack height adjustment for the testing equipment to prevent injury from manual handling at high temperatures. Therefore, this utility model provides a textile fabric air permeability testing device to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a textile fabric air permeability testing device to solve the problems mentioned in the background art. The existing textile fabric air permeability testing devices do not have a fabric clamping mechanism, which causes the fabric to shift during testing and cause testing errors. Secondly, the textile fabric air permeability testing devices cannot adjust the clamping distance of the clamping equipment according to the fabric length. Finally, the textile fabric air permeability testing devices do not have the function of raising and lowering the testing equipment to avoid injury from manual handling at high temperatures.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a textile fabric air permeability testing device, comprising: a workbench for installation, a first test container stably installed at the upper middle part of the workbench, and telescopic rods installed on the left and right sides of the upper part of the workbench. It also includes: a lateral adjustment mechanism is provided on the first test container, wherein the lateral adjustment mechanism includes a support frame, a fixed rod, a connecting frame, a bidirectional threaded screw and a sliding block, a fixed rod is provided on the upper rear side of the support frame, a connecting frame is connected to the outer side of the fixed rod, a bidirectional threaded screw is connected to the front end of the connecting frame, and a sliding block is provided on the right end of the bidirectional threaded screw; A telescopic rod is provided with a lifting mechanism at its upper end. The lifting mechanism includes a connecting plate and a second test container. The upper end of the telescopic rod is connected to the connecting plate, and the middle part of the connecting plate is provided with the second test container.

[0007] Preferably, the connecting frame forms a sliding structure on the outside of the fixed rod, and the connecting frame is arranged about the center line of the fixed rod.

[0008] Preferably, the connecting frame is provided with a sliding rod and a first spring inside, and the outer side of the sliding rod is in contact with the first spring, and a rubber pad is provided at the lower end of the sliding rod.

[0009] Preferably, the front end of the connecting frame is connected to the bidirectional threaded screw by means of threads, and the right end of the bidirectional threaded screw is provided with a second spring and a sliding block, with the sliding block located outside the second spring.

[0010] Preferably, the right end of the bidirectional threaded screw is configured in a cross shape, and the sliding block forms a sliding structure at the right end of the bidirectional threaded screw, with a locking block provided at the left end of the sliding block.

[0011] Preferably, the card block and the card slot are connected by a snap-fit ​​mechanism, and the card slot is fixedly installed on the inner right side wall of the support frame.

[0012] Preferably, the lower end of the second test container is fitted with the first test container, and a controller is provided at the rear end of the second test container, the lower end of which is fixedly connected to the workbench.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects: the air permeability testing device for textile fabrics makes it easy to adjust the spacing of the clamping devices on the testing device to meet the clamping requirements of different fabrics, makes it easy to prevent the devices for adjusting the clamping spacing on the testing device from loosening, and makes it easy to adjust the height of the testing device to test fabrics of different thicknesses. 1. Equipped with a fixed rod, a connecting frame, and a bidirectional threaded screw, when the clamping distance needs to be adjusted according to the fabric length, the sliding block is pinched to drive the bidirectional threaded screw to rotate, causing the thread on the bidirectional threaded screw to move the connecting frame to the left and right sides. The connecting frame then slides on the fixed rod, ultimately enabling the connecting frame to drive the clamping device to adjust to the appropriate position, clamping and limiting the fabric to prevent the fabric from shifting during testing, which would affect the test results. This also facilitates the adjustment of the clamping distance on the testing device to meet the clamping requirements of different fabrics. 2. Equipped with a second spring, a sliding block, and a slot, after the clamping device spacing is adjusted, to prevent loosening, the sliding block is initially in a rightward sliding state. When the sliding block is released, the elastic force of the second spring causes the sliding block to slide back to the right. During the displacement, the sliding block also causes the slot to engage with the corresponding slot, thereby stabilizing and limiting the sliding block. By limiting the sliding block, the bidirectional threaded screw is fixed in position to prevent loosening, which facilitates the anti-loosening treatment of the clamping spacing adjustment device on the testing device. 3. Equipped with a telescopic rod, a connecting plate, and a second test container, when the textile fabric test is completed and the testing equipment needs to be adjusted to avoid skin damage from manual control, the controller uses sensors to control the telescopic rod to start working synchronously. This allows the telescopic rod to lift the second test container upwards using the connecting plate. Simultaneously, the telescopic rod and the second test container enable compression testing of fabrics of different thicknesses, facilitating the adjustment of the testing device to test fabrics of varying thicknesses.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figures 1-6 The present invention provides the following technical solution: A textile fabric air permeability testing device includes: a workbench 1, a first test container 2, a support frame 3, a fixed rod 4, a connecting frame 5, a sliding rod 6, a first spring 7, a rubber pad 8, a bidirectional threaded screw 9, a second spring 10, a sliding block 11, a locking block 12, a locking groove 13, a telescopic rod 14, a connecting plate 15, a second test container 16, and a controller 17. When adjusting the spacing of the clamping devices on the testing apparatus, for example, attaching... Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 and attached Figure 6As shown, the connecting frame 5 forms a sliding structure on the outside of the fixed rod 4. The connecting frame 5 is positioned about the center line of the fixed rod 4. The front end of the connecting frame 5 is connected to the bidirectional threaded screw 9 by a thread. The right end of the bidirectional threaded screw 9 is provided with a second spring 10 and a sliding block 11. The sliding block 11 is located outside the second spring 10. The right end of the bidirectional threaded screw 9 is set in a cross shape. The sliding block 11 forms a sliding structure on the right end of the bidirectional threaded screw 9. The left end of the sliding block 11 is provided with a locking block 12. The locking block 12 is connected to the locking groove 13 by a locking method. The locking groove 13 is fixedly set on the right inner wall of the support frame 3. First, adjust the clamping device spacing according to the fabric length, pinch the sliding block 11 to drive the bidirectional threaded screw 9 forward. The rotation causes the thread on the bidirectional threaded screw 9 to move the connecting frame 5 to the left and right sides. The connecting frame 5 then slides on the fixed rod 4, ultimately enabling the connecting frame 5 to drive the clamping device to adjust to a suitable position and clamp and limit the fabric. To prevent the bidirectional threaded screw 9 from loosening and affecting the clamping device, the sliding block 11 is released at this time. The elastic force of the second spring 10 drives the sliding block 11 to slide to the right to return to its original position. When the sliding block 11 is displaced, it also drives the locking block 12 to engage in the corresponding locking groove 13, thereby stabilizing and limiting the sliding block 11. By limiting the position of the sliding block 11, the bidirectional threaded screw 9 is fixed, thus limiting the clamping device. This is the method of using the clamping device on the testing device to adjust the spacing. When using textile fabric breathability testing equipment, such as... Figure 1 Appendix Figure 2 and attached Figure 3As shown, the connecting frame 5 is internally equipped with a sliding rod 6 and a first spring 7. The outer side of the sliding rod 6 is in contact with the first spring 7. A rubber pad 8 is provided at the lower end of the sliding rod 6. Telescopic rods 14 are installed on the left and right sides of the upper end of the workbench 1. The upper end of the telescopic rods 14 is connected to a connecting plate 15. A second test container 16 is provided in the middle of the connecting plate 15. The lower end of the second test container 16 is in contact with the first test container 2. A controller 17 is provided at the rear end of the second test container 16. The lower end of the controller 17 is fixedly connected to the workbench 1. First, water is poured into the first test container 2. The controller 17 is used to heat the water in the first test container 2. The fabric is placed on the first test container 2. The connecting frame 5 is then... The internal sliding rod 6 slides downwards. When the sliding rod 6 is displaced, it compresses the first spring 7 downwards. When the sliding rod 6 rotates, it connects with the internal thread of the connecting frame 5 through the thread. The sliding rod 6 eventually drives the rubber pad 8 to clamp and fix the fabric. After the fabric clamping limit is completed, the controller 17 controls the telescopic rod 14 to start working synchronously through the sensor. The telescopic rod 14 uses the connecting plate 15 to drive the second test container 16 to move downwards as a whole. The telescopic rod 14 drives the second test container 16 to squeeze and test fabrics of different thicknesses. By observing the atomization of the fabric through the steam inside the first test container 2 to the inner wall of the second test container 16, its air permeability is detected. This is how the textile fabric air permeability testing device is used. This is the entire working process of the textile fabric air permeability testing device.
