Description

Technical Field

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

[0002] Textile fabrics are the materials used to make clothing. Textile fabrics can not only interpret the style and characteristics of clothing, but also directly affect the color and shape of clothing. Waterproof textile fabrics need to be manufactured according to different usage scenarios and then processed into clothes. After the waterproof textile fabrics are processed, waterproof testing is required to check whether the waterproof performance of the textile fabric is qualified.

[0003] A patent with publication number CN116642818B discloses a device for testing the waterproof performance of fabrics. When testing the waterproofness of fabrics, if the waterproof level is not excellent, the water above the fabric will drip onto the impact plate through the fabric. When all the test water is sprayed, the total equivalent amount minus the equivalent amount accumulated above the impact plate is removed by the total equivalent amount, and the waterproof rate of the fabric can be obtained in percentage. When the water accumulated above the impact plate reaches a certain level, the lifting plate on the impact plate moves to the upper limit of the lifting rod, and then the moving contact piece on the first base contacts the static contact piece on the sleeve in the collection box. The alarm sounds an alarm to remind the operator that the waterproof effect of the fabric does not meet the standard, so that scientific test data is stored when testing the waterproofness of the fabric, thereby improving the accuracy of the test results.

[0004] In the above-mentioned prior art, when water is sprayed on the fabric, whether the waterproof performance of the fabric is qualified is judged by observing whether the water penetrates the fabric. If the fabric does not penetrate water, the waterproof level of the fabric can be judged by observing the water droplets remaining on the fabric. The fewer the water droplets remaining on the upper end of the fabric, the higher the waterproof level, and vice versa. When conducting waterproof performance testing in the prior art, it is necessary to combine visual observation with other tests. When performing visual observation, since water is transparent, misjudgment may occur during observation, and the waterproof level of the fabric may be inaccurately judged.

DETAILED DESCRIPTION

[0030] 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.

[0031] Example 1

[0032] like Figure 1-Figure 2As shown, a textile fabric waterproof performance testing device described in an embodiment of the present invention includes a first cylinder 1, a second ring 14 is provided at the upper end of the first cylinder 1, the second ring 14 can slide to the outside of the upper end of the first cylinder 1, a nozzle 16 is provided at the upper end of the first cylinder 1, a second rectangular plate 3 is fixed to the lower end of the first cylinder 1, a pressing device is provided on one side of the first cylinder 1, the pressing device includes a first rectangular plate 2 provided on one side of the first cylinder 1, a cotton cloth 22 is provided at the lower end of the first rectangular plate 2, and the first rectangular plate 2 can drive the cotton cloth 22 to slide to the upper end of the first cylinder 1.

[0033] Specifically, when testing fabrics, a sample is usually taken, stretched straight, and water is sprinkled on the fabric to observe whether the water penetrates the fabric at any time. If water penetrates the fabric, it means that the waterproof performance of the fabric is unqualified. If water does not penetrate the fabric, it is necessary to observe whether there are residual water droplets on the fabric. The fewer the residual water droplets, the higher the waterproof performance of the fabric. In the existing technology, the distribution of water droplets on the fabric is often observed with the naked eye during testing. Since water is transparent, misjudgment may occur during observation, and the judgment of the waterproof level of the fabric is inaccurate. When using the present detection device, the waterproof fabric is placed on the upper end of the first cylinder 1, and then the second ring 14 is driven to slide downward. The second ring 14 slides downward along the edge of the waterproof fabric until it slides to the outside of the first cylinder 1. At this time, the edge of the waterproof fabric is located between the second ring 14 and the first cylinder 1, so that the waterproof fabric is in a straight state. Then the nozzle 16 is driven to spray water on the upper end of the fabric to observe whether the water penetrates the fabric. If the water penetrates the fabric, it means that the fabric is waterproof and unqualified. If the water does not penetrate the fabric, the first rectangular plate 2 is then driven to drive the cotton cloth 22 to slide downward, so that the cotton cloth 22 contacts the waterproof fabric, and the cotton cloth 22 absorbs the remaining water on the upper end of the waterproof fabric. Since the cotton cloth 22 is more absorbent and the watermark is more obvious, by observing the water absorbed by the cotton cloth 22, the distribution of the water droplets remaining on the upper end of the waterproof fabric can be intuitively seen, thereby accurately judging the waterproof level of the waterproof fabric, solving the problem of misjudgment by directly observing the distribution of water droplets on the fabric with the naked eye.

[0034] like Figure 4 As shown, a second cylinder 11 is slidably provided inside the lower end of the first cylinder 1. The second cylinder 11 is fixed to the inside of the first cylinder 1 through a first spring 113. Rectangular holes 12 are respectively provided on both sides of the lower end of the first cylinder 1. First rectangular blocks 111 are respectively fixed on both sides of the second cylinder 11. The first rectangular blocks 111 can slide in the rectangular holes 12 respectively.

[0035] Specifically, when water is sprayed on the upper end of the waterproof fabric for testing, if water penetrates the waterproof fabric, the water will fall into the second cylinder 11. The weight of the water falling into the second cylinder 11 increases, causing the second cylinder 11 to slide downward at the lower end of the first cylinder 1 and stretch the first spring 113, while driving the first rectangular block 111 to slide downward in the rectangular hole 12. By observing whether the first rectangular block 111 slides downward, it can be directly judged whether the waterproof performance of the fabric is qualified. At the same time, the second cylinder 11 can also collect the falling water.

[0036] like Figure 5 As shown, an extrusion assembly is provided inside the second ring 14 , which includes an annular groove 141 provided inside the middle of the second ring 14 , and arc-shaped extrusion blocks 143 are fixed to one side of the annular groove 141 through a plurality of second springs 142 .

[0037] Specifically, when the second ring 14 is driven to slide downward to fix the waterproof fabric, the second ring 14 drives several arc-shaped extrusion blocks 143 to contact the waterproof fabric, so that one side of the arc surface of the arc-shaped extrusion block 143 contacts the waterproof fabric, and then drives the waterproof fabric to slide downward to contact the outside of the first cylinder 1. The arc-shaped extrusion block 143 slides into the annular groove 141 and squeezes the second spring 142. Through the squeezing of the arc-shaped extrusion block 143, the waterproof fabric is fixed more firmly.

[0038] like Figure 4-Figure 5 As shown, a first ring 13 is fixed to the middle of the outer side of the first cylinder 1 , a plurality of conical grooves 131 are fixed around the upper end of the first ring 13 , and a plurality of conical blocks 144 are fixed to the positions of the lower end of the second ring 14 corresponding to the conical grooves 131 .

[0039] Specifically, the second ring 14 is driven to drive the waterproof fabric to move continuously downward until the several conical blocks 144 drive the waterproof fabric to be inserted into the conical groove 131. At this time, the waterproof fabric is located between the conical blocks 144 and the conical groove 131, further fixing the waterproof fabric.

[0040] like Figure 2-Figure 3As shown, a second rectangular block 152 is fixedly connected to one side of the second circular ring 14, and a first slide rail 15 is slidably provided on one side of the second rectangular block 152. The lower end of the first slide rail 15 is rotatably connected to the first circular plate 151, and the lower end of the first circular plate 151 is fixed to the second rectangular plate 3. The upper end of the second circular ring 14 is fixed to the nozzle 16 through L-shaped strips 162. The upper end of the nozzle 16 is fixed to the water inlet pipe 161. The second circular ring 14 is fixed to the side away from the second rectangular block 152. A third rectangular block 17 is fixed to one side of the third rectangular block 17. A first arc block 171 is fixed to one side of the first arc block 171. A second arc block 172 is fixed to one side of the second arc block 172. A second slide rail 18 is provided on one side of the second arc block 172. The second slide rail 18 is fixed to the second rectangular plate 3. A third arc block 181 is slidably provided on one side of the second slide rail 18. A arc groove 1811 is provided on one side of the third arc block 181, and the second arc block 172 can slide in the arc groove 1811.

[0041] Specifically, when installing the waterproof fabric, first drive the second ring 14 to rotate to the side of the first cylinder 1 to facilitate the placement of the waterproof fabric. After the waterproof fabric is placed, drive the first slide rail 15 to rotate on the upper end of the first circular plate 151. The first slide rail 15 drives the second ring 14 to rotate to the upper end of the first cylinder 1 through the second rectangular block 152. At the same time, the second ring 14 drives the third rectangular block 17 to rotate. The third rectangular block 17 drives the second arc block 172 to rotate into the arc groove 1811 through the first arc block 171. Then drive the second rectangular block 152 to slide in the first slide rail 15, driving the second ring 14 to slide downward. At the same time, the third rectangular block 17 drives the first arc block 171 to slide downward on the side of the second slide rail 18 through the second arc block 172. When driving the second ring 14 to slide downward, the stability of the second ring 14 can be guaranteed to prevent the second ring 14 from shifting.

[0042] like Figure 6 As shown, the lower end of the second rectangular plate 3 is provided with an angle adjustment device, the angle adjustment device includes a third rectangular plate 32 rotatably connected to one side of the lower end of the second rectangular plate 3 through a fourth rectangular block 31, the fourth rectangular block 31 is fixed to the upper end of the third rectangular plate 32, the lower end of the second rectangular plate 3 is rotatably connected to the side away from the fourth rectangular block 31, the connecting rod 33 is rotatably connected to the fifth rectangular block 34, the middle part of the fifth rectangular block 34 is threadedly connected to a screw rod 35, one end of the screw rod 35 is rotatably connected to one side of the fourth rectangular block 31, and the fifth rectangular block 34 can slide on the upper end of the third rectangular plate 32.

[0043] Specifically, after water is sprayed on the waterproof fabric, the screw rod 35 is driven to rotate, driving the fifth rectangular block 34 to slide to the side away from the fourth rectangular block 31. The fifth rectangular block 34 drives the second rectangular plate 3 and the third rectangular plate 32 to rotate through the connecting rod 33, so that one side of the second rectangular plate 3 tilts upward, and at the same time drives the first cylinder 1 to tilt, so that excess water on the upper end of the waterproof fabric slides off, and then drives the first rectangular plate 2 to drive the cotton cloth 22 to absorb the remaining water droplets on the upper end of the waterproof fabric, so that the detection result is more accurate.

[0044] like Figure 4 As shown, the middle part of the second rectangular plate 3 is a hollow structure, and a drain pipe 112 is fixedly connected to the lower end of the second cylinder 11 . The end of the drain pipe 112 away from the second cylinder 11 is tilted upward and passes through the outer side of the second rectangular plate 3 .

[0045] Specifically, since one end of the drain pipe 112 is tilted upward, water will not flow out of the drain pipe 112 when entering the second cylinder 11 . When the second rectangular plate 3 is driven to tilt, the water in the second cylinder 11 can be discharged along the drain pipe 112 .

[0046] like Figure 7 As shown, the two ends of one side of the first rectangular plate 2 are rotatably connected to the second cylindrical wheel 241 through the second rectangular bar 24, and the two ends of the other side of the first rectangular plate 2 are rotatably connected to the first cylindrical wheel 231 through the first rectangular bar 23. The second rectangular bar 24 is arranged perpendicular to the first rectangular bar 23. The outer side of the second cylindrical wheel 241 is used to install the rolled cotton cloth 22, and the first cylindrical wheel 231 is used to install the end of the rolled cotton cloth 22. The middle part of the first rectangular bar 23 is rotatably connected to two third cylindrical wheels 26, and the cotton cloth 22 is in a right angle shape.

[0047] Specifically, when the first rectangular plate 2 is driven to drive the cotton cloth 22 to move to the upper end of the first cylinder 1, the water droplets remaining on the upper end of the waterproof fabric are absorbed, and then the first cylindrical wheel 231 is driven to rotate, driving the end of the cotton cloth 22 to be wrapped around the outside of the first cylindrical wheel 231, and at the same time pulling out the rolled cotton cloth 22 on the outside of the second cylindrical wheel 241, driving the cotton cloth 22 located at the lower end of the first rectangular plate 2 to move to the side of the two third cylindrical wheels 26, so that the cotton cloth 22 with water droplets is moved from the lower end of the first rectangular plate 2 to the side, making it convenient to observe the distribution of watermarks on the cotton cloth 22, and at the same time, the new cotton cloth 22 can be pulled out to the lower end of the first rectangular plate 2 for easy use next time.

[0048] Example 2

[0049] like Figure 8As shown, compared with Example 1, another embodiment of the present invention is: second circular holes 211 are respectively provided around the upper end of the first rectangular plate 2, and cylindrical blocks 213 are respectively fixed to the inside of the second circular holes 211 through third springs 212, and the upper ends of several cylindrical blocks 213 are commonly fixed to a second circular plate 214, and a water bag 215 is fixed to the middle of the lower end of the second circular plate 214, and the water bag 215 is located in the first circular hole 21.

[0050] Specifically, when the first rectangular plate 2 drives the cotton cloth 22 to fit tightly against the waterproof fabric, the water bag 215 contacts the cotton cloth 22 and squeezes the cotton cloth 22 downward to fit the waterproof fabric. The lower part of the water bag 215 is arc-shaped, which can make the cotton cloth 22 fit tightly against the waterproof fabric, making the adsorption effect of the cotton cloth 22 better.

[0051] like Figure 7 As shown, an L-shaped plate 25 is fixed to one side of the first rectangular plate 2 , a rectangular tube 251 is slidably provided at the lower end of the L-shaped plate 25 , a third slide rail 252 is slidably provided at the lower end of the rectangular tube 251 , and the third slide rail 252 is fixed to the second rectangular plate 3 .

[0052] Specifically, by driving the rectangular tube 251 to slide on the upper end of the third slide rail 252, the first rectangular plate 2 is driven by the L-shaped plate 25 to move toward the side close to the first cylinder 1 until the first rectangular plate 2 is located at the upper end of the first cylinder 1, and then the L-shaped plate 25 is driven to slide downward in the rectangular tube 251. The L-shaped plate 25 drives the first rectangular plate 2 and the cotton cloth 22 to slide downward, so that the water droplets on the surface of the waterproof fabric can be absorbed.

[0053] Working principle: when installing the waterproof fabric, first drive the second ring 14 to rotate to the side of the first cylinder 1, then place the waterproof fabric on the upper end of the first cylinder 1, and then drive the first slide rail 15 to rotate on the upper end of the first circular plate 151. The first slide rail 15 drives the second ring 14 to rotate to the upper end of the first cylinder 1 through the second rectangular block 152. At the same time, the second ring 14 drives the third rectangular block 17 to rotate. The third rectangular block 17 drives the second arc block 172 to rotate into the arc groove 1811 through the first arc block 171. Then, the second rectangular block 152 is driven to slide in the first slide rail 15, driving the second ring 14 to slide downward. At the same time, the third rectangular block 17 drives the second arc block 172 to rotate into the arc groove 1811. The first arc block 171 slides downward on one side of the second slide rail 18, and the second ring 14 drives the plurality of arc-shaped extrusion blocks 143 to contact the waterproof fabric, so that one side of the arc surface of the arc-shaped extrusion block 143 contacts the waterproof fabric, and then drives the waterproof fabric to slide downward to contact the outside of the first cylinder 1. The arc-shaped extrusion block 143 slides into the annular groove 141 and squeezes the second spring 142. The waterproof fabric is fixed by the squeezing of the arc-shaped extrusion block 143. The second ring 14 drives the waterproof fabric to continue to move downward until the plurality of conical blocks 144 drive the waterproof fabric to be inserted into the conical groove 131. At this time, the waterproof fabric is located between the conical block 144 and the conical groove 131, further fixing the waterproof fabric.

[0054] Then, the nozzle 16 is driven to spray water on the upper end of the fabric. If the water penetrates the waterproof fabric, the water will fall into the second cylinder 11. The weight of the water falling into the second cylinder 11 increases, causing the second cylinder 11 to slide downward at the lower end of the first cylinder 1 and stretch the first spring 113. At the same time, it drives the first rectangular block 111 to slide downward in the rectangular hole 12. By observing whether the first rectangular block 111 slides downward, it can be directly judged whether the waterproof performance of the fabric is qualified. At the same time, the second cylinder 11 can also collect the falling water.

[0055] When it is observed that the fabric is not water-permeable, the screw rod 35 is driven to rotate, driving the fifth rectangular block 34 to slide to the side away from the fourth rectangular block 31, and the fifth rectangular block 34 drives the second rectangular plate 3 and the third rectangular plate 32 to rotate through the connecting rod 33, so that one side of the second rectangular plate 3 tilts upward, and at the same time drives the first cylinder 1 to tilt, so that excess water on the upper end of the waterproof fabric slides off, and drives the rectangular cylinder 251 to slide on the upper end of the third slide rail 252, and drives the first rectangular plate 2 to move closer to the first cylinder 1 through the L-shaped plate 25 until the first rectangular plate 2 is located at the upper end of the first cylinder 1, and then drives the L-shaped plate 25 to slide downward in the rectangular cylinder 251, and the L-shaped plate 25 drives the first rectangular plate 2 and the cotton cloth 22 to slide downward, so that the cotton cloth 22 is close to the waterproof cloth, and the water bag 215 contacts the cotton cloth 22 and presses the cotton cloth 22 downward to fit the waterproof cloth. The lower part of the water bag 215 is arc-shaped, which can make the cotton cloth 22 fit closely with the waterproof cloth, so that the adsorption effect of the cotton cloth 22 is better;
