Description

Technical Field

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

[0002] Fabrics are materials made from fibers through various textile processes. They are ubiquitous in our daily lives, with wide applications and an important role. After the fabric is woven, its water permeability is tested. Therefore, fabric water permeability testing equipment is needed. Existing fabric water permeability testing equipment usually uses a certain pressure or hydrostatic pressure system to apply water to the fabric sample. The water permeability of the fabric is determined by measuring parameters such as the amount of water passing through the fabric under specific conditions, the water flow velocity, or the time.

[0003] For example, a fabric permeability testing device with prior art publication number CN221803756U continuously injects water into the inlet pipe and uses water pressure to raise the water from low to high into the riser box, and then from the riser box into the upper cylinder. This greatly reduces the impact force of the water flow, reduces the increase in the permeability of textiles caused by the impact force of the water flow, and improves the accuracy of the test.

[0004] However, the existing technology has the following problems when used: when testing the water permeability of fabrics, the experimenter needs to check the air permeability of the fabric in real time. Manual judgment will not only lead to errors in the water permeability test results, but also result in low testing efficiency. Based on this, the present invention provides a fabric water permeability testing device with high testing efficiency. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a fabric permeability testing device. The fabric and the film are installed through frame one and frame two. When the film surface comes into contact with water droplets, the film surface is induced by voltage. As the size of the water droplets gradually increases, the corresponding voltage value increases. The size of the water droplets at the manually determined endpoint is converted into the corresponding electrical signal intensity as the test endpoint, and the test endpoint of the fabric experiment is finally determined. The device automatically detects, reduces manpower, and has high detection accuracy, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fabric permeability testing device, comprising a permeability measuring instrument, an upper clamp on the permeability measuring instrument, a lower clamp adapted to the upper clamp fixedly on the top of the permeability measuring instrument, multiple support plates fixedly on the top of the permeability measuring instrument, a sensing mechanism between the multiple support plates, the sensing mechanism comprising a first frame, the first frame being disposed between the multiple support plates, a second frame being detachably fixedly on the top of the first frame, a thin film being disposed between the second frame and the first frame, multiple sensing circuits being fixedly disposed on the top of the thin film, a fabric to be tested being disposed between the bottom of the thin film and the first frame, and the fabric to be tested being disposed on the top of the lower clamp.

[0007] In a preferred embodiment, multiple sensing circuits are arranged in a ring array on the top surface of the film, and all multiple sensing circuits are electrically connected to the water permeability tester for transmitting voltage signals.

[0008] In a preferred embodiment, the bottom of the second frame is fixed with multiple positioning rods, and the top of the first frame is provided with multiple positioning slots. The multiple positioning rods are inserted into the multiple positioning slots respectively, which makes it easy for the experimenter to quickly install the second frame and the first frame together.

[0009] In a preferred embodiment, each support plate has a spring pin fixedly inserted through its outer wall. The outer wall surface of the frame is provided with multiple slots that are adapted to the spring pins. The spring pins are inserted into the slots to facilitate the installation and disassembly of the frame and the support plate by the experimenter.

[0010] In a preferred embodiment, the upper clamp includes a pressure ring, a bracket is fixedly provided on the top of the pressure ring, a threaded rod is rotatably connected to the top of the bracket, the top of the threaded rod passes through the permeability tester and is threadedly connected to the permeability tester, and a crank is fixedly provided on the top of the threaded rod. Cranking the crank causes the threaded rod to rotate, and the pressure ring can be moved down by means of the threaded rod, so as to facilitate the adjustment of the height of the pressure ring.

[0011] In a preferred embodiment, the permeability tester has water guide grooves on both sides of its top, and a transparent acrylic cover is provided on the top of the permeability tester. The transparent acrylic cover is fitted over the outside of the upper and lower clamps, and the bottom of the transparent acrylic cover is located inside the water guide groove. The transparent acrylic cover seals the water guide groove to prevent the experimental water from flowing directly out of the permeability tester.

[0012] In a preferred embodiment, the permeability tester is fixedly equipped with detachable electric push rods on both sides of its top. The piston rods of the two electric push rods are fixed to the outer wall of the transparent acrylic cover. The transparent acrylic cover is automatically raised and lowered by the electric push rods, which facilitates the discharge of experimental water.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model uses frame one and frame two to install fabric and film. When the film surface comes into contact with water droplets, the film surface is induced by voltage. As the size of the water droplets gradually increases, the corresponding voltage value increases.

[0024] 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 protection scope of the present utility model.

[0025] Refer to the instruction manual appendix Figure 1-5 This utility model provides a fabric permeability testing device, including a permeability tester 1. The permeability tester 1 is provided with an upper clamp 2. Specifically, the upper clamp 2 includes a pressure ring 201. A bracket 202 is fixedly provided on the top of the pressure ring 201. A threaded rod 203 is rotatably connected to the top of the bracket 202. The top of the threaded rod 203 passes through the permeability tester 1 and is threadedly connected to the permeability tester 1. A crank 204 is fixedly provided on the top of the threaded rod 203. Cranking the crank 204 drives the threaded rod 203 to rotate. With the help of the threaded rod 203, the pressure ring 201 can be moved down, which makes it easy to adjust the height of the pressure ring 201.

[0026] Next, a lower clamp 3 adapted to the upper clamp 2 is fixedly installed on the top of the permeability tester 1. Multiple support plates 4 are fixedly installed on the top of the permeability tester 1, and a sensing mechanism 5 is provided between the multiple support plates 4. The sensing mechanism 5 includes a first frame 501, which is located between the multiple support plates 4. A second frame 502 is detachably fixed on the top of the first frame 501. A thin film 503 is provided between the second frame 502 and the first frame 501. Multiple sensing circuits 504 are fixedly installed on the top of the thin film 503. The multiple sensing circuits 504 are arranged in a ring array on the top surface of the thin film 503. All multiple sensing circuits 504 are electrically connected to the permeability tester 1 for transmitting voltage signals.

[0027] The bottom of the film 503 is provided with the fabric to be tested 6 between the bottom of the film 503 and the frame 501. The fabric to be tested 6 is located on the top of the lower clamp 3. The bottom of the frame 502 is fixed with multiple positioning rods 7. The top of the frame 501 is provided with multiple positioning slots 8. The multiple positioning rods 7 are inserted into the multiple positioning slots 8 respectively, so that the experimenter can quickly install the frame 502 and the frame 501 together.

[0028] Furthermore, a spring pin 9 is fixedly inserted through the outer wall of each support plate 4. The outer wall surface of the frame 1 501 is provided with multiple slots 10 that are adapted to the spring pin 9. The spring pin 9 is inserted into the slot 10, which facilitates the installation and disassembly of the frame 2 502 and the support plate 4 by the experimenter.

[0029] In use, the experimenter first places the fabric to be tested inside frame one 501, then lays the film 503 flat on the surface of the fabric, and then fixes frame two 502 together with frame one 501. After fixing frame one 501 and frame two 502, frame one 501 is placed between multiple support plates 4, which support frame one 501 and frame two 502. Multiple spring pins 9 are used to fix frame one 501 to the support plates 4. Then, the crank handle 204 is turned to drive the pressure ring. 201 moves down, so that the pressure ring 201 cooperates with the lower clamp 3 to press the fabric and the film 503 together, and the water permeability test can be carried out. Specifically, the water permeability tester 1 is a publicly available technology, so it is not described in detail. Using frame one 501 and frame two 502 to install the film 503 and the fabric, the film 503 can be attached to the surface of the fabric and participate in the entire water permeability test process together with the fabric, without affecting the accuracy of the test, and it is convenient for the test personnel to disassemble the film 503 and the fabric for replacement.

[0030] In the water permeability test, multiple sensing circuits 504 on the membrane 503 are electrically connected to the water permeability tester 1. When the surface of the membrane 503 comes into contact with a water droplet, the surface of the membrane 503 is induced by electrical signals such as voltage. As the size of the water droplet gradually increases, the corresponding voltage value increases accordingly. Specifically, since water is injected into the wetted surface of the textile from the center, the water permeates and diffuses on both the upper and lower surfaces of the textile. By continuously monitoring the sampling voltage, the moisture content data of the textile in multiple sensing circuits 504 can be obtained. After a large number of experimental verifications, the size of the water droplet at the endpoint determined by humans is converted into the corresponding electrical signal intensity as the test endpoint. Finally, the test endpoint of the experiment is achieved by sensing the specified electrical signal intensity, avoiding human detection differences, automatic detection, reducing manpower, and high detection accuracy.

[0031] Refer to the instruction manual appendix Figure 1-5 The water permeability tester 1 has water guide grooves 11 on both sides of the top. The top of the water permeability tester 1 is provided with a transparent acrylic cover 12. The transparent acrylic cover 12 is fitted on the outside of the upper clamp 2 and the lower clamp 3, and the bottom of the transparent acrylic cover 12 is located inside the water guide groove 11. The transparent acrylic cover 12 seals the water guide groove 11 to prevent the experimental water from flowing directly out of the water permeability tester 1.

[0032] The permeability tester 1 is equipped with detachable electric push rods 13 on both sides of the top. The piston rods of the two electric push rods 13 are fixed to the outer wall of the transparent acrylic cover 12. The transparent acrylic cover 12 is automatically raised and lowered by the electric push rods 13 to facilitate the discharge of experimental water.

[0033] By setting a transparent acrylic cover 12 on the top of the water permeability tester 1, the upper clamp 2 and the lower clamp 3 are covered by the transparent acrylic cover 12 to prevent the experimental water from splashing out. After use, the transparent acrylic cover 12 can be moved upward by the electric push rod 13, so that the transparent acrylic cover 12 is slowly moved out of the water guide trough 11. The experimental water flows out through the water guide trough 11, which makes it convenient for the experimenters to use a box to collect and recycle the experimental water, thus reducing the experimental cost.

[0034] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
