Description
Technical Field
[0001] This invention relates to the field of novel home textile fabric testing technology, specifically a device for testing the waterproofness of home textile fabrics. Background Technology
[0002] Home textile fabrics are rapidly developing towards multifunctionality, environmental friendliness, and high performance. New home textile materials such as bamboo fiber, Tencel (lyocell fiber), recycled PET (rPET) base fabrics, and intelligent temperature-regulating composite fabrics are constantly emerging and widely used in bedding, bathroom textiles, and other fields. These new materials often integrate waterproof, antibacterial, breathable, and environmentally friendly functions. Their waterproof performance directly affects the product's user experience and lifespan. Therefore, accurate waterproof testing throughout the entire production chain is crucial and a core element in ensuring product quality and market compliance.
[0003] The prior art (Chinese patent publication number: CN117233060A, publication date: December 15, 2023) discloses a waterproof testing device for home textile fabrics, including a base. A vertical plate is fixed at the middle of the top of the base, and a rotating column is rotatably connected inside the middle of the vertical plate. A drive mechanism for rotating the rotating column is provided at the bottom of the inner cavity of the vertical plate. A movable plate is fixedly connected to the top of the rotating column. A support plate is provided above the movable plate, and the movable plate and the support plate are rotatably connected. A water spraying mechanism for spraying water is provided at the top of the inner cavity of the support plate. This device can test the waterproofness of home textile fabrics under different tensile forces, making the test results more accurate. It can also switch between two workstations, which not only improves the testing efficiency but also reduces the workload of workers loading and unloading materials. Furthermore, it can speed up the drying process of the home textile fabrics after the test. The prior art (Chinese patent publication number: CN116642818A, publication date: August 25, 2023) discloses a fabric waterproof performance testing device. However, this prior art cannot accurately measure the percentage of waterproof performance, lacking scientific testing data and reducing the accuracy of the test results. The device includes a base plate with symmetrically mounted side plates connected to a support plate. A first bearing is mounted on the support plate, and a support shaft is mounted on the first bearing. The support shaft passes through a locking block and is connected to a drive gear. A handle is mounted on the drive gear, and the locking block is connected to a driving locking unit. The drive gear meshes with two drive racks, which are connected to a tightening force mechanism. A fixed-point delay mechanism alerts the operator that the fabric's waterproof performance is substandard, providing scientific testing data and improving the accuracy of the test results. The prior art (publication number: CN119470207) also includes this device. Chinese Patent B, published on September 12, 2025, discloses a device for testing the waterproof performance of textile fabrics. The device includes a first cylinder with a second ring at its upper end, the second ring being slidable to the outer side of the upper end of the first cylinder. A nozzle is located at the upper end of the first cylinder, and a second rectangular plate is fixedly connected to the lower end of the first cylinder. A pressing device is located on one side of the first cylinder, the pressing device including a first rectangular plate on one side of the first cylinder. A cotton cloth is located at the lower end of the first rectangular plate. The first rectangular plate can drive the cotton cloth to slide to the upper end of the first cylinder, where the cotton cloth absorbs the remaining water on the upper end of the waterproof fabric. By observing the water absorbed by the cotton cloth, the distribution of the remaining water droplets on the upper end of the waterproof fabric can be visually observed, thereby accurately determining the waterproof rating of the waterproof fabric.
[0004] Most existing waterproof testing devices for home textile fabrics use a single spray test or dynamic impact penetration test, which makes it impossible to simulate and test the fabric in multiple ways, making it inconvenient to test the waterproof performance of the fabric under different conditions, and failing to ensure the accuracy of the test data, thus having certain limitations in use. Summary of the Invention
[0005] The purpose of this invention is to provide a waterproof testing device for home textile fabrics, in order to solve the problems mentioned in the background art. Most waterproof testing devices for home textile fabrics on the market currently adopt a single spray test method or dynamic impact penetration test method, which makes it impossible to conduct multi-mode simulation testing of the fabric, inconvenient to test the waterproof performance of the fabric under different conditions, and unable to ensure the accuracy of the test data.

[0007] Preferably, the two ends of the adjusting screw have opposite thread directions, and the adjusting screw and the movable support frame are threadedly connected. The movable support frame slides against the upper surface of the fixed frame, and the adjusting screw drives the two movable support frames to move synchronously during rotation.
[0008] Preferably, two guide posts are symmetrically fixedly installed on the outer side of the movable plate, and the guide posts slide through the movable support frame, and a spring is fixedly connected between the movable support frame and the end of the guide posts.
[0009] Preferably, the clamping assembly includes a first clamping roller mounted on an adjusting frame, and a second clamping roller is connected to the outside of the first clamping roller by a spring, and the first clamping roller and the second clamping roller clamp and fix the end of the fabric under the action of the spring force.
[0010] Preferably, the first clamping roller is elastically rotatably mounted on the adjusting frame, and a first pull rope is wound around the shaft of the first clamping roller, and the lower end of the first pull rope is fixedly connected to the upper surface of the fixed frame. At the same time, during the movement of the adjusting frame, the first pull rope pulls the first clamping roller to rotate.
[0011] Preferably, the rotating shaft has a first guide groove, which is arranged in a straight line, and a ball bearing is embedded in the movable support frame, while the ball bearing slides along the first guide groove.
[0012] Preferably, the outer wall of the rotating shaft is provided with a second guide groove, and the second guide groove is spirally arranged. The first guide groove and the second guide groove are connected end to end. At the same time, the ball drives the rotating shaft to rotate the adjusting frame as it slides along the second guide groove.
[0013] Preferably, the adjusting frame has an annular sliding groove, and limit rods are symmetrically fixedly installed on the movable plate, and the limit rods and the sliding groove are slidably connected.
[0014] Preferably, the transmission assembly includes an incomplete gear that is rotatably mounted on the outside of the fixed side frame, and a second pull rope is wound around the outside of the shaft of the incomplete gear, and the lower end of the second pull rope is fixedly connected to the movable support frame. A transmission gear is fixedly connected to the outside of the movable spray pipe, and the incomplete gear and the transmission gear are meshed together.
[0015] Compared with the prior art, the beneficial effects of the present invention are: the waterproof testing device for home textile fabrics can stably clamp and position the fabric, and can realize multi-mode testing, which effectively improves the accuracy of waterproof testing. The specific details are as follows; 1. The device is equipped with a first clamping roller and a second clamping roller. The first clamping roller and the second clamping roller can move closer to each other under the elastic force of the spring to achieve initial clamping and fixing of the fabric end. As the movable support frame moves, the first pull rope will pull the first clamping roller to rotate, so that the first clamping roller and the second clamping roller can wrap around the fabric end, thereby further improving the clamping stability of the fabric.
[0016] 2. Equipped with a movable spray pipe, ball bearings, and a first guide groove, after the static spray test is completed, the movable support frame continues to move. Due to the limitation of the fabric, the guide column slides on the movable support frame. At this time, the movable support frame and the movable plate move away from each other. Then, the second pull rope pulls the incomplete gear to rotate, so that the incomplete gear drives the transmission gear and the movable spray pipe to rotate back and forth through meshing, realizing swing spraying and dynamic spray test, further improving the test accuracy.
[0017] 3. Equipped with a rotating shaft, ball bearings, and a second guide groove, after the dynamic spray test is completed, the movable support frame continues to move, causing the ball bearings to enter the inner side of the second guide groove. As the ball bearings slide along the second guide groove, they can drive the rotating shaft to rotate the adjusting frame. The two adjusting frames rotate in opposite directions, thereby twisting the clamped fabric to simulate the daily friction of the fabric. This makes the waterproof test of the fabric more in line with actual use conditions and further improves the accuracy of the test data. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Example 1: Existing home textile fabric waterproofing testing devices use a single fabric clamping method, resulting in limited fabric clamping stability. To address this technical problem, this example discloses the following technical details. Please refer to [link / reference]. Figures 1-5 As shown; A waterproof testing device for home textile fabrics includes a water tank 1, a fixed frame 2 fixedly installed above the water tank 1, a collection trough 24 fixedly installed on the fixed frame 2, a visual detector 23 fixedly installed on the side wall of the collection trough 24, a motor 3 fixedly installed on the fixed frame 2, an adjusting screw 4 fixedly installed at the output end of the motor 3, a movable support frame 5 symmetrically connected to the outer side of the adjusting screw 4, a movable plate 7 elastically telescopically connected to the outer side of the movable support frame 5, a rotating shaft 8 rotatably installed through the movable plate 7, and the rotating shaft 8 slidably passes through the movable support frame 5. An adjusting frame 9 is fixedly installed at the end of the rotating shaft 8, and a clamping component for fixing the fabric is installed on the adjusting frame 9.
[0022] The two ends of the adjusting screw 4 have opposite thread directions, and the adjusting screw 4 is threadedly connected to the movable support frame 5. The movable support frame 5 slides against the upper surface of the fixed frame 2. Simultaneously, the adjusting screw 4 drives the two movable support frames 5 to move synchronously during rotation. Two guide posts 6 are symmetrically fixedly installed on the outer side of the movable plate 7, and the guide posts 6 slide through the movable support frames 5. A spring is fixedly connected between the ends of the movable support frames 5 and the guide posts 6. The clamping assembly includes a first clamping roller 10 mounted on the adjusting frame 9. The outer side of the first clamping roller 10 is connected to the second clamping roller 11 by a spring. The first clamping roller 10 and the second clamping roller 11 clamp and fix the end of the fabric under the action of the spring force. The first clamping roller 10 is elastically rotatably mounted on the adjusting frame 9. The shaft of the first clamping roller 10 is wound with a first pull rope 12, and the lower end of the first pull rope 12 is fixedly connected to the upper surface of the fixing frame 2. At the same time, during the movement of the adjusting frame 9, the first pull rope 12 pulls the first clamping roller 10 to rotate.
[0023] During the preparation for testing, the end of the fabric is placed between the first clamping roller 10 and the second clamping roller 11. The first clamping roller 10 and the second clamping roller 11 can move closer to each other under the elastic force of the spring, achieving initial clamping and fixing of the end of the fabric. As the motor 3 is started, the motor 3 drives the adjusting screw 4 to rotate, which in turn drives the movable support frame 5 to slide on the fixed frame 2. At the same time, under the elastic force of the spring, the fixed frame 2 will drive the movable plate 7 to move synchronously. The first pull rope 12 will pull the first clamping roller 10 to rotate, so that the first clamping roller 10 and the second clamping roller 11 can wrap around the end of the fabric, thereby further improving the clamping stability of the fabric.
[0024] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. Most existing home textile fabric waterproofing testing devices employ a single spray test or dynamic impact penetration test, making it impossible to perform multi-mode simulation testing of the fabric and inconvenient to test the fabric's waterproofing performance under different conditions. To further solve this technical problem, this example discloses the following technical content: Figures 2-9 As shown; a fixed side frame 15 is fixedly installed on the movable plate 7, and a movable spray pipe 16 is rotatably installed on the fixed side frame 15. The end of the movable spray pipe 16 is rotatably connected to a water supply pipe, and the water supply pipe is connected to the water tank 1 through the pump body. A transmission component is connected between the movable spray pipe 16 and the movable support frame 5. When the movable support frame 5 and the movable plate 7 move relative to each other, the transmission component drives the movable spray pipe 16 to reciprocate.
[0025] A first guide groove 18 is provided on the rotating shaft 8, and the first guide groove 18 is arranged in a straight line. A ball bearing 17 is embedded in the movable support frame 5 and slides along the first guide groove 18. A second guide groove 19 is also provided on the outer wall of the rotating shaft 8, and the second guide groove 19 is arranged in a spiral shape. The first guide groove 18 and the second guide groove 19 are connected end to end. During the sliding of the ball bearing 17 along the second guide groove 19, the rotating shaft 8 is driven to rotate the adjusting frame 9. An annular sliding groove 13 is provided on the adjusting frame 9. Limiting rods 14 are symmetrically fixed on the movable plate 7 and are slidably connected to the sliding groove 13. The transmission component includes an incomplete gear 20 that is elastically rotatably installed on the outside of the fixed side frame 15. A second pull rope 21 is wound around the outside of the shaft of the incomplete gear 20 and the lower end of the second pull rope 21 is fixedly connected to the movable support frame 5. A transmission gear 22 is fixedly connected to the outside of the movable spray pipe 16 and the incomplete gear 20 and the transmission gear 22 are meshed.
[0026] After the fabric is clamped and unfolded, the movable spray pipe 16 is controlled to perform static spraying on the fabric surface. The permeability of the fabric can be observed through the visual detector 23, and the collection tank 24 can collect the dripping water. After the static spraying test is completed, the movable support frame 5 is controlled to continue moving. Due to the constraint of the fabric, the guide post 6 slides on the movable support frame 5. At this time, the movable support frame 5 and the movable plate 7 move away from each other. At this time, the ball bearing 17 slides along the first guide groove 18. The first guide groove 18 is linearly distributed, which can prevent the rotating shaft 8 from rotating. At the same time, the second pull rope 21 pulls the incomplete gear 20 to rotate, so that the incomplete gear 20 drives the transmission gear 22 and the movable spray pipe through meshing. The spray pipe 16 reciprocates to achieve oscillating spraying, realizing dynamic spraying detection and further improving detection accuracy. After the dynamic spraying detection is completed, the movable support frame 5 is controlled to continue moving, so that the ball bearing 17 enters the inner side of the second guide groove 19. As the ball bearing 17 slides along the second guide groove 19, it can drive the rotating shaft 8 to drive the adjusting frame 9 to rotate. The two adjusting frames 9 rotate in opposite directions, thereby twisting the clamped fabric to simulate the daily friction of the fabric, so that the waterproof detection of the fabric is more in line with actual use. Then, the adjusting frame 9 is controlled to reset, and the movable spray pipe 16 is used to spray the rubbed fabric for detection, further improving the accuracy of the detection data.
