Description

Technical Field

[0001] The invention belongs to the technical field of textile testing, in particular to a device for testing the waterproof performance of textiles. Background Art

[0002] Waterproof fabric is a special-purpose textile, mostly used in products such as umbrellas and waterproof jackets. During the production process of waterproof fabric, it is necessary to test the waterproof performance of the waterproof fabric. For some waterproof fabrics with higher waterproof grade requirements, the waterproof fabric is not only required to have the ability to repel water, but also to have a certain static pressure anti-penetration ability.

[0003] A patent with publication number CN118961547B discloses a device for testing the waterproof performance of textile fabrics. By setting a collecting device, the device can support the lower surface of the textile fabric and collect the water flow that passes through the textile fabric, so as to compare it with the total water pouring volume, thereby achieving the effect of testing the waterproof performance of the textile fabric. By setting a fabric clamping device, the ends of the fabric can be clamped and cooperated with the collecting device so that the two ends of the fabric are tightened, thereby making the fabric located on the upper surface of the connecting box flat. By setting a water inlet device, the upper surface of the fabric can be squeezed, and after the fabric is flattened, the upper surface of the fabric can be injected with water, and the water flow that has not passed through can be discharged and collected, thereby facilitating subsequent comparison of the waterproof amount.

[0004] The above scheme still has some problems in actual application. Usually, the fabric is spread flat on the table of the testing table, and then the fabric is covered with a storage tube and pressed to fix it. At the same time, clean water is poured into the storage tube, and the time for the clean water to penetrate the fabric is observed. However, this testing method requires waiting for a long time to observe the time for the clean water to penetrate the fabric, resulting in low efficiency in fabric waterproofness testing. Moreover, it is difficult for existing testing devices to pressurize the clean water used for fabric testing, resulting in some special fabrics. It is difficult to detect the waterproofness of the fabric using only the clean water penetration method, resulting in low fabric testing efficiency.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] Example 1: Figures 1 to 9 As shown, a waterproof performance testing device for textiles according to an embodiment of the present invention includes a workbench 1, a testing platform 2 is installed on the upper end of the workbench 1, two slide rods 4 are slidably connected to the inner cavity of the workbench 1, a T-shaped scraper 18 is installed on the upper end of the slide rod 4, and water-absorbing brushes are evenly arranged on the lower end of the T-shaped scraper 18, a first spring 16 is fixed to the inner wall of the workbench 1, one end of the first spring 16 is fixed to the slide rod 4, both ends of the two slide rods 4 are rotatably connected to a support rod 7, one end of the support rod 7 is rotatably connected to an H-shaped fixing block 14, and a pressure detection component 8 is installed between the H-shaped fixing blocks 14; The pressure detection assembly 8 includes a pressure cylinder 81 installed between the H-shaped fixing blocks 14. A water inlet 15 is provided at one end of the pressure cylinder 81. A second sealing disk 88 is provided in the inner cavity at the lower end of the pressure cylinder 81. A plurality of drainage holes are evenly provided at the lower end of the second sealing disk 88 for draining clean water to test the waterproofness of the textile. A detection port 5 is provided on the upper end surface of the detection platform 2. A humidity detection probe is provided in the inner cavity of the detection port 5 for real-time monitoring of the humidity of the textile. A pressure monitor 10 is installed in one end of the pressurizing cylinder 81 for real-time monitoring of the water pressure in the inner cavity of the pressurizing cylinder 81.

[0023] Specifically, in the prior art, the fabric is usually laid flat on the surface of the testing table, and then a storage cylinder is used to cover the fabric and press it to fix it. At the same time, clean water is poured into the storage cylinder, and the time for the clean water to penetrate the fabric is observed. However, this testing method requires waiting for a long time to observe the time for the clean water to penetrate the fabric, resulting in low efficiency in fabric waterproofness testing. In addition, the existing testing device cannot pressurize the clean water in the storage cylinder, resulting in that the waterproofness of some special fabrics cannot be tested simply by using clean water penetration. After the fabric test is completed, the fabric must be collected and the testing table must be wiped dry with a sponge or towel before the subsequent fabric waterproofness test can be performed. This is not only cumbersome but also affects the fabric testing efficiency. The present invention drives the two sliding rods 4 to move closer to each other, thereby causing the two sliding rods 4 to drive the support rods 7 to move synchronously, and at the same time the support rod 7 pushes the H-shaped fixing block 14 to move upward, and causes the H-shaped fixing block 14 to drive the pressure cylinder 81 to move upward away from the detection table 2, and then the fabric is laid on the detection table 2, and at the same time the two sliding rods 4 are driven to slide away from each other in the inner cavity of the workbench 1, thereby causing the sliding rod 4 to drive the support rod 7 to move synchronously, and at the same time the support rod 7 drives the H-shaped fixing block 14 to move downward, and causes the H-shaped fixing block 14 to drive the pressure cylinder 81 to move downward, so that the pressure cylinder 81 can press and fix the fabric on the detection table 2, and at the same time the pressure cylinder 81 can also seal the detection port 5, and then use the pressure pump to pour clean water into the inner cavity of the pressure cylinder 81 through the water inlet 15, so that the clean water in the inner cavity of the pressure cylinder 81 passes through the second sealing disk 88 The water is discharged from the drainage hole, and as the pressure pump continues to pour clean water into the pressure cylinder 81 to increase the pressure, the pressure monitor 10 is used to monitor the water pressure in the inner cavity of the pressure cylinder 81 in real time, so that the clean water puts pressure on the fabric, and then the humidity of the fabric at one end face of the detection port 5 is monitored in real time by the humidity detection probe, and then the fabric is observed to see whether it is waterproof after being subjected to a quantitative water pressure. After the waterproof condition of the fabric is detected, the pressure cylinder 81 is driven to move upward, and the slide rod 4 drives the T-shaped scraper 18 to move toward the detection port 5. Since the lower end of the T-shaped scraper 18 is evenly provided with a water-absorbing brush, the T-shaped scraper 18 can be used to clean the surface of the detection port 5. The water stains remaining in the waterproof detection can be cleaned by the T-shaped scraper 18, and the water-absorbing brush can be used to absorb and dry the water stains on the surface of the detection port 5 to avoid affecting the subsequent fabric detection effect, thereby solving the above problem.

[0024] like Figure 1 、 Figure 5 and Figure 6As shown, a first motor 11 is installed at the upper end of the pressure cylinder 81, and a screw 82 is fixedly connected to the output shaft end of the first motor 11. One end of the screw 82 is rotatably connected to the second sealing disk 88. The external thread of the screw 82 is connected to the piston disk 83. A groove is provided on the inner wall of the pressure cylinder 81, and the piston disk 83 slides in the inner cavity of the groove and can move up and down through the threaded transmission of the screw 82. A plurality of one-way valves are provided inside the upper end surface of the piston disk 83, and the plurality of one-way valves can only be flipped open toward the upper part of the inner cavity of the pressure cylinder 81.

[0025] Specifically, after the fabric on the test platform 2 is covered and pressed and fixed by the pressure cylinder 81, the first motor 11 is started at the same time to drive the screw rod 82 to rotate, and the screw rod 82 is threaded to drive the second sealing plate 88 to slide back and forth in the inner cavity of the pressure cylinder 81. When the piston plate 83 moves upward, it will squeeze the clean water in the upper part of the pressure cylinder 81 to form pressure, and then the clean water will squeeze open the one-way valve inside the piston plate 83, so that the clean water will flow into the lower part of the pressure cylinder 81. When the piston plate 83 moves downward, the piston plate 83 will draw the air in the upper part of the inner cavity of the pressure cylinder 81 to create negative pressure, and then draw external clean water into the inner cavity of the pressure cylinder 81 through the water inlet 15. As the piston plate 83 continues to reset, it can continuously pressurize the lower part of the inner cavity of the pressure cylinder 81, so that the clean water puts pressure on the fabric, and then observe the waterproof data of the fabric after a certain pressure, thereby improving the efficiency of fabric waterproofness detection.

[0026] like Figure 1 、 Figure 5 and Figure 6 As shown, a plurality of receiving grooves 85 are provided at the lower end of the pressurizing cylinder 81, and a second spring 86 is fixed to the bottom of the inner cavity of the plurality of receiving grooves 85, and a first sealing disk 87 is fixed to one end of the second spring 86. The first sealing disk 87 is slidably connected in the inner cavity of the pressurizing cylinder 81, and the lower end surface of the first sealing disk 87 is located in the inner cavity of the receiving groove 85 and is fixed with a sliding column 84.

[0027] like Figure 1 、 Figure 5 and Figure 6 As shown, a plurality of plug posts 89 are evenly fixed to the lower end surface of the first sealing disk 87, and a plurality of plug posts 89 are evenly fixed to the upper end surface of the second sealing disk 88. A plurality of water outlets are evenly opened inside the upper end surfaces of the first sealing disk 87 and the second sealing disk 88, and the water outlets in the first sealing disk 87 and the water outlets of the second sealing disk 88 are staggered with each other, and the plug posts 89 on the lower end surface of the first sealing disk 87 are plugged and sealed with the water outlet of the second sealing disk 88, whereas the plug posts 89 on the upper end surface of the second sealing disk 88 are plugged and sealed with the water outlet of the first sealing disk 87, so as to seal the inner cavity of the pressurized cylinder 81.

[0028] Specifically, by driving the pressure cylinder 81 downward to cover and press the fabric on the testing platform 2, and during the downward movement of the pressure cylinder 81, the pressure cylinder 81 will drive the sliding post 84 to abut against the testing platform 2, and then as the pressure cylinder 81 continues to move downward, the sliding post 84 will slide into the inner cavity of the receiving groove 85, and at the same time the sliding post 84 will push the first sealing plate 87 to move synchronously, thereby causing the first sealing plate 87 to squeeze the second spring 86 to drive the plug post 89 to move upward, thereby causing the plug post 89 to slide out of the water outlet of the second sealing plate 88, and the plug post 89 at the upper end of the second sealing plate 88 will slide out of the water outlet of the first sealing plate 87, thereby causing the clean water to flow into the second sealing plate 88 through the water outlet of the first sealing plate 87, and at the same time contact the fabric through the water outlet of the second sealing plate 88, and the second sealing plate 88 has multiple water outlets, thereby realizing multi-point and multi-point treatment of a piece of fabric. At the same time, waterproof testing is performed to improve the efficiency of fabric waterproof testing. After the fabric waterproof test is completed, the pressure cylinder 81 is driven to move upward, and the second spring 86 is used to push the first sealing disk 87 to move downward, so that the first sealing disk 87 drives the plug 89 to be inserted into the water outlet of the second sealing disk 88, and at the same time, the second sealing disk 88 drives the plug 89 to be inserted into the water outlet of the first sealing disk 87, thereby sealing the inner cavity of the pressure cylinder 81 to prevent clean water from continuously flowing out to perform waterproof testing on the fabric, thereby solving the problem that when the existing textile waterproof testing device performs waterproof testing on the fabric, it is inconvenient to simultaneously test the waterproofness of multiple points and multiple places of a piece of fabric, resulting in inaccurate test results, and a single-point waterproof test cannot represent the waterproof performance of the entire batch of fabrics. If the bottom of the storage cylinder is not sealed after the test is completed, all the clean water in the storage cylinder will flow out, affecting the subsequent fabric testing.

[0029] like Figure 1 、 Figure 3 and Figure 9 As shown, a recovery drive assembly 9 is provided on the lower end surface of the workbench 1, and the recovery drive assembly 9 includes a conical recovery cylinder 91 installed inside the lower end surface of the workbench 1, and the conical recovery cylinder 91 is rotatably connected to an intermittent gear ring 92 on the outside, and two transmission blocks 93 are fixed to the outside of the intermittent gear ring 92, and one end of the two transmission blocks 93 is rotatably connected to a pull rod 94, and one end of the pull rod 94 is rotatably installed with a T-shaped push plate 95, and two limit grooves 97 are provided on the lower end surface of the workbench 1, and the T-shaped push plate 95 is slidably connected in the inner cavity of the limit groove 97.

[0030] like Figure 1 、 Figure 3 and Figure 9 As shown, the intermittent gear ring 92 is externally engaged with a gear disc 96, a servo motor is installed inside the lower end of the workbench 1, the output shaft end of the servo motor is fixedly connected to the gear disc 96, the upper end of the conical recovery cylinder 91 is fixedly installed on the detection table 2, and the inner cavity of the conical recovery cylinder 91 is connected to the detection port 5.

[0031] Specifically, before testing the waterproofness of the fabric, the servo motor is started to drive the gear plate 96 to rotate, and the gear plate 96 engages the transmission intermittent gear ring 92 to rotate, thereby causing the intermittent gear ring 92 to drive the transmission block 93 to rotate, and at the same time, the transmission block 93 drives the pull rod 94 to rotate. During the rotation of the pull rod 94, it will drive the T-shaped push plate 95 to slide in the inner cavity of the limit groove 97 and move close to each other, thereby causing the T-shaped push plate 95 to push the slide bar 4 to move synchronously, thereby causing the slide bar 4 to squeeze the first spring 16 to drive the support rod 7 to rotate, and at the same time, the support rod 7 drives the H-shaped fixed block 14 to move upward, and the H-shaped fixed block 14 drives the pressurizing cylinder 81 to move upward, thereby facilitating the operator to lay the fabric flat on the testing table 2, and during the upward movement of the pressurizing cylinder 81, the slide bar 4 will also synchronously drive the T-shaped scraper 18 to move synchronously, thereby causing the T-shaped scraper 18 to contact the surface of the testing table 2. The surface is cleaned and wiped of residual water stains, and then the gear disc 96 is driven to rotate and reset, thereby engaging the gear disc 96 to transmit the intermittent gear ring 92 to rotate, and the intermittent gear ring 92 drives the transmission block 93 to rotate, thereby rotating the transmission pull rod 94 of the transmission block 93, and then pushing the T-shaped pushing plate 95 to move away from each other. At the same time, the first spring 16 pushes the slide bar 4 to slide outside the fixed column 3 and move away from each other, thereby causing the slide bar 4 to drive the support rod 7 to pull the H-shaped fixed block 14 to move downward, and at the same time, the H-shaped fixed block 14 drives the pressurizing cylinder 81 to cover and press the fabric on the test table 2 to fix it, thereby solving the problem that the existing textile waterproofness testing device needs to wipe the test table dry with a sponge or towel before the fabric can be spread flat on the test table for waterproofness testing, which is not only cumbersome to operate but also affects the fabric testing efficiency.

[0032] Example 2: Figure 2 、 Figure 4 and Figure 6 As shown, the lower end of the conical recovery cylinder 91 is fixedly connected to a connecting pipe 12, one end of the connecting pipe 12 is fixedly connected to a folding pipe 13, one end of the folding pipe 13 is fixedly connected to the connecting pipe 12, and one end of the connecting pipe 12 is fixedly connected to the water inlet 15. A one-way valve is provided in the inner cavity of the water inlet 15, and the one-way valve can only be flipped open toward the inner cavity of the folding pipe 13.

[0033] like Figure 1 、 Figure 7 and Figure 8As shown, a detection auxiliary component 6 is installed on the upper end surface of each sliding rod 4, and the detection auxiliary component 6 includes two mounting frames 61 installed on both sides of the sliding upper end surface, and a winding drum 62 is rotatably connected between the two mounting frames 61, and a bidirectional threaded rod 63 is rotatably connected to the inner cavity of the winding drum 62, and the bidirectional threaded rod 63 is externally threadedly connected to a sliding plate 64, and the sliding plate 64 is externally rotatably connected to a connecting rod 65, and one end of the connecting rod 65 is rotatably connected to a splint 66, and the splint 66 is slidably connected in the inner cavity of the winding drum 62 for clamping the textile for stretching.

[0034] Specifically, when testing the same batch of fabrics, the cloth roll is installed on the outside of the take-up drum 62, and the crank 67 is twisted to drive the two-way threaded rod 63 to rotate, and the two-way threaded rod 63 is threaded to drive the two sliding plates 64 to move away from each other, so that the sliding plates 64 drive the connecting rod 65 to move synchronously, and at the same time the connecting rod 65 pushes the clamping plate 66 to slide out of the take-up drum 62 for expansion, and then the clamping plate 66 is used to expand and fix the cloth roll, and at the same time, one end of the cloth roll is pulled through the pressure cylinder 81, and one end of the cloth roll is inserted between the clamping plate 66 and the take-up drum 62, and then the two-way threaded rod 63 is driven to thread the sliding plate 64. They move closer to each other, thereby causing the sliding plate 64 to drive the connecting rod 65 to move closer to each other, and at the same time, the connecting rod 65 drives the clamping plate 66 to slide into the inner cavity of the take-up drum 62, thereby causing the clamping plate 66 to clamp and fix one end of the cloth roll. In the process of the sliding rods 4 moving away from each other, the take-up drum 62 will be driven to move synchronously, thereby causing the take-up drum 62 to pull the cloth roll into a stretched state and unfold it, solving the problem that the existing textile waterproofness testing device needs to waste a lot of collection and flattening of the fabric before performing waterproof testing on the fabric, and ensure that the fabric is stretched straight and has no wrinkles, which causes cumbersomeness and affects the fabric testing efficiency.

[0035] like Figure 1 、 Figure 7 and Figure 8 As shown, a crank 67 is rotatably connected to one end of the winding drum 62 , and one end of the crank 67 is fixedly connected to the bidirectional threaded rod 63 . A second motor 68 is installed inside one of the mounting frames 61 , and the output shaft end of the second motor 68 is fixedly connected to the winding drum 62 .

[0036] Specifically, after the installation of the cloth roll to be tested is completed, the second motor 68 is started to rotate the take-up drum 62 to drive the cloth roll to rotate and release the cloth, so that different positions of the fabric can be quickly tested, thereby solving the problem that the existing textile waterproofness testing device can only test one fabric position at a time, the test samples are small, resulting in inaccurate testing results and cannot be applied to large-scale waterproof fabric performance testing.

[0037] like Figure 2 and Figure 3As shown, two fixed columns 3 are installed in the inner cavity of the workbench 1, and two sliding rods 4 are slidably connected to the outside of the fixed columns 3. A through groove 19 is opened on the upper end surface of the testing platform 2, and the T-shaped scraper 18 is slidably connected in the inner cavity of the through groove 19. A rubber pad 17 is provided at the lower end of the pressure cylinder 81. The testing port 5 adopts a sunken setting, and the pressure cylinder 81 can be inserted into the inner cavity of the testing port 5 for pressing and tightening the textiles to improve the accuracy of waterproof testing.

[0038] The working principle is to drive the two sliding rods 4 to move closer to each other, thereby causing the two sliding rods 4 to drive the support rod 7 to move synchronously, and at the same time the support rod 7 pushes the H-shaped fixing block 14 to move upward, and causes the H-shaped fixing block 14 to drive the pressure cylinder 81 to move upward away from the testing table 2, and then lay the fabric on the testing table 2, and at the same time drive the two sliding rods 4 to slide away from each other in the inner cavity of the workbench 1, thereby causing the sliding rod 4 to drive the support rod 7 to move synchronously, and at the same time the support rod 7 drives the H-shaped fixing block 14 to move downward, and causes the H-shaped fixing block 14 to drive the pressure cylinder 81 to move downward, so that the pressure cylinder 81 can press and fix the fabric on the testing table 2, and at the same time the pressure cylinder 81 can also seal the testing port 5, and then use the pressure pump to pour clean water into the inner cavity of the pressure cylinder 81 through the water inlet 15, so that the clean water in the inner cavity of the pressure cylinder 81 passes through the second sealing The water is discharged from the drainage hole of the sealing disk 88, and as the pressure pump continues to pour clean water into the pressure cylinder 81 to increase the pressure, the pressure monitor 10 is used to monitor the water pressure in the inner cavity of the pressure cylinder 81 in real time, so that the clean water puts pressure on the fabric, and then the humidity of the fabric at one end face of the detection port 5 is monitored in real time by the humidity detection probe, and then the fabric is observed to see whether it is waterproof after being subjected to a quantitative water pressure. After the waterproof condition of the fabric is detected, the pressure cylinder 81 is driven to move upward, and the slide bar 4 drives the T-shaped scraper 18 to move toward the detection port 5. Since the lower end of the T-shaped scraper 18 is evenly provided with a water-absorbing brush, the T-shaped scraper 18 can be used to clean the surface of the detection port 5 from residual water stains during the waterproof detection, and the water-absorbing brush can be used to absorb and dry the water stains on the surface of the detection port 5 to avoid affecting the subsequent fabric detection effect. The pressure cylinder 81 is driven to move downward to cover and press the fabric on the test platform 2. During the downward movement of the pressure cylinder 81, the pressure cylinder 81 drives the slide post 84 to contact the test platform 2. Then, as the pressure cylinder 81 continues to move downward, the slide post 84 slides into the inner cavity of the receiving groove 85. At the same time, the slide post 84 pushes the first sealing disk 87 to move synchronously, so that the first sealing disk 87 squeezes the second spring 86 to drive the plug post 89 to move upward, so that the plug post 89 slides out from the water outlet of the second sealing disk 88, and the plug post 89 at the upper end of the second sealing disk 88 slides out from the water outlet of the first sealing disk 87, so that the clean water flows into the water outlet of the first sealing disk 87 through the water outlet of the first sealing disk 87. The second sealing disc 88 is between the two sealing discs 88, and contacts the fabric through the water outlet of the second sealing disc 88. The second sealing disc 88 is provided with multiple water outlets, thereby being able to realize the waterproof detection of multiple points and multiple places of a piece of fabric at the same time, thereby improving the efficiency of the fabric waterproof detection. After the waterproof detection of the fabric is completed, the pressure cylinder 81 is driven to move upward, and the second spring 86 is used to push the first sealing disc 87 to move downward, so that the first sealing disc 87 drives the plug 89 to be inserted into the water outlet of the second sealing disc 88. At the same time, the second sealing disc 88 drives the plug 89 to be inserted into the water outlet of the first sealing disc 87, thereby sealing the inner cavity of the pressure cylinder 81 to prevent the continuous outflow of clean water to perform the waterproof detection on the fabric; When the cloth roll is inspected, the cloth roll is installed outside the take-up drum 62 and the crank 67 is twisted to drive the two-way threaded rod 63 to rotate, and the two-way threaded rod 63 threadedly drives the two sliding plates 64 to move away from each other, thereby causing the sliding plate 64 to drive the connecting rod 65 to move synchronously, and the connecting rod 65 pushes the clamping plate 66 to slide out of the take-up drum 62 to expand, and then the cloth roll is expanded and fixed by the clamping plate 66, and at the same time pulls one end of the cloth roll through the pressure cylinder 81 and inserts one end of the cloth roll between the clamping plate 66 and the take-up drum 62, and then drives the two-way threaded rod 63 to thread the sliding plate 64 to move closer to each other, thereby causing the sliding plate 64 to drive the connecting rod 65 to move closer to each other, and at the same time the connecting rod 65 drives the clamping plate 66 to slide into the inner cavity of the take-up drum 62, thereby causing the clamping plate 66 to clamp and fix one end of the cloth roll, and when the slide rods 4 move away from each other, the take-up drum 62 will be driven to move synchronously, thereby causing the take-up drum 62 to pull the cloth roll to be stretched and unfolded.
