The absorbent cotton is hermetically arranged on the back of the fabric to be tested. After the water spraying test is completed, the fabric and the absorbent cotton are taken off, and the weight of the absorbent cotton is measured again by the weighing instrument. The difference between the weights of the absorbent cotton measured before and after is the amount of water that has penetrated through the fabric during the water spraying test. Thus, the waterproof performance of the fabric can be judged by the measured water penetration amount. By absorbing the water that has penetrated through the fabric with the absorbent cotton, the water that has penetrated through the fabric can be completely absorbed. At the same time, the absorbent cotton is hermetically arranged on the back of the fabric to be tested and will not be affected by the splashing water flow from the outside, so that the collected water amount is exactly the same as the water amount that has penetrated through the fabric, which is beneficial to improving the accuracy of the fabric waterproof test.

[0026] 2. In the present invention, the turntable drives the substrate and the fabric thereon to perform circular motion, and at the same time, the swing driving assembly drives the support shaft to reciprocally swing, so that the support shaft drives the substrate and the fabric to reciprocally swing, thereby enabling the fabric to perform the water spraying test during the circular motion and the swinging process for dynamic waterproof testing of the fabric. On the other hand, during the water spraying test, the fabric can also be driven by the turntable and the swing driving assembly to be adjusted to a certain angle and then the turntable stops rotating, so that the fabric can maintain this angle for static water spraying test. Thus, through the cooperation of the turntable and the swing driving assembly, the fabric can be driven to perform static waterproof testing at different angles. Through the dynamic waterproof testing and the static waterproof testing at different angles, the comprehensiveness and accuracy of the fabric waterproof testing can be improved.

[0027] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Embodiment 1

[0041] Please refer to Figures 1 - 3As shown in the figure, the present invention is a waterproof testing device, including a testing machine body 1. At the lower end of the front side of the testing machine body 1, a water collecting tank 11 is provided. At the upper end of the testing machine body 1, a spray head 5 is installed directly above the water collecting tank 11. Inside the water collecting tank 11, a positioning mechanism 3 for positioning the fabric to be tested and a swinging mechanism 2 for driving the positioning mechanism 3 to adjust the angle and swing reciprocally are provided; the swinging mechanism 2 includes a turntable 21, a swing driving assembly, and a support shaft 29. The turntable 21 is rotatably installed at the bottom inside the water collecting tank 11, and the turntable 21 is in transmission connection with a motor installed inside the bottom of the testing machine body 1. The support shaft 29 is installed on the top surface of the turntable 21 through the swing driving assembly, and the swing driving assembly can drive the support shaft 29 to swing reciprocally when the turntable 21 rotates; the positioning mechanism 3 includes a substrate 31, a water-absorbing cotton 32, and a positioning component. The substrate 31 is fixedly installed on the top surface of the support shaft 29. The positioning component can position and install the water-absorbing cotton 32 and the fabric to be tested on the substrate 31, and the water-absorbing cotton 32 is hermetically arranged on the back of the fabric to be tested;

[0042] Specifically, before the test, first measure the weight of the unused dry water-absorbing cotton 32 with a weighing instrument, and then position and install the water-absorbing cotton 32 and the fabric to be tested on the substrate 31 through the positioning component, and the water-absorbing cotton 32 is hermetically arranged on the back of the fabric to be tested; then pour water downward through the spray head 5, and at the same time drive the turntable 21 to rotate through the motor, so that the turntable 21 drives the substrate 31 and the fabric thereon to do circular motion, and at the same time the swing driving assembly drives the support shaft 29 to swing reciprocally, so that the support shaft 29 drives the substrate 31 and the fabric to swing reciprocally, so that the fabric undergoes a water spraying test during the circular motion and the swinging process; after the water spraying test is completed, turn off the spray head 5 and the motor, remove the fabric and the water-absorbing cotton 32, and measure the weight of the water-absorbing cotton 32 again with a weighing instrument. The difference between the weights of the water-absorbing cotton 32 measured before and after is the amount of water that has penetrated through the fabric during the water spraying test, so that the waterproof performance of the fabric can be judged through the measured water penetration amount;

[0043] Among them, the absorbent cotton 32 absorbs the water that has permeated through the fabric, and can completely absorb the water that has permeated through the fabric. At the same time, the absorbent cotton 32 is hermetically arranged on the back of the fabric to be tested and will not be affected by external splashing water flows, so that the amount of water collected is exactly the same as the amount of water permeating through the fabric, which is beneficial to improving the accuracy of the fabric waterproof test; the turntable 21 and the swing drive assembly can drive the fabric to perform a water spraying test during circular motion and swinging to conduct a dynamic waterproof test on the fabric. On the other hand, after the turntable 21 and the swing drive assembly drive the fabric to be adjusted to a certain angle, the turntable 21 can be stopped from rotating, so that the fabric can maintain this angle for a static water spraying test. Thus, through the cooperation of the turntable 21 and the swing drive assembly, the fabric can be driven to perform static waterproof tests at different angles. Through the dynamic waterproof test and the static waterproof tests at different angles, the comprehensiveness and accuracy of the fabric waterproof test can be improved.

[0044] Furthermore, a water baffle 12 is fixedly installed at the lower end of the testing machine body 1 and is located in front of the water collecting tank 11. A diversion groove 13 is arranged on the outer ring of the water collecting tank 11. A liquid discharge port communicating with the outside of the testing machine body 1 is arranged at the bottom end of the diversion groove 13. The diversion groove 13 can collect and divert the water sprayed during the test to facilitate the collection and discharge of the sprayed water. The water baffle 12 can block and protect the front side of the testing machine body 1 to prevent the sprayed water from splashing outside the testing machine body 1.

[0045] Embodiment 2

[0046] Please refer to Figure 3 、 Figures 5 - 7 As shown, the difference between this embodiment and the above embodiment is that the positioning component includes a plurality of buckles 33 and clamping grooves 36. The clamping grooves 36 are formed on the top surface of the substrate 31. A bearing box 34 is movably clamped in the clamping grooves 36. A loading groove 37 is arranged in the bearing box 34. The absorbent cotton 32 is clamped in the loading groove 37. A ring buckle 35 is sleeved on the outer ring of the top end of the bearing box 34. The plurality of buckles 33 are evenly distributed in a circle and are rotatably installed on the outer ring of the substrate 31, and the buckles 33 can clamp and lock the ring buckle 35 on the top surface of the substrate 31.

[0047] Before the test, the absorbent cotton 32 is snapped into the loading slot 37, and then the carrying box 34 and the absorbent cotton 32 are weighed together by a weighing instrument. Thereafter, the carrying box 34 is snapped into the slot 36, and the fabric to be tested is spread on the surface of the carrying box 34 so that the fabric covers the absorbent cotton 32. Then the buckle 35 is covered on the surface of the fabric, and the buckle 35 is locked and fixed by the buckle 33, so that the buckle 35 locks and fixes the fabric and the carrying box 34. When the sprinkler 5 sprays water, water drops fall on the fabric. When water penetrates to the back of the fabric, it is absorbed by the absorbent cotton 32. When the spraying is completed, the buckle 33 is rotated to open, and the buckle 35 and the carrying box 34 are removed in turn. Then the carrying box 34 and the absorbent cotton 32 are weighed together by a weighing instrument. The difference between the weight before and after weighing is the amount of water that penetrates through the fabric.

[0048] Embodiment 3

[0049] See also Figure 1 , Figure 2 , Figures 5 - 8 As shown, the difference between this embodiment and the above embodiment is that the swing drive assembly includes a base 210, the base 210 is fixedly mounted on the outer ring of the top surface of the turntable 21, a universal ball bearing 211 is mounted on the top of the base 210, a support seat 212 is fixedly mounted on the top of the universal ball bearing 211, a support shaft 29 is fixedly mounted on the top of the support seat 212, and two symmetrically distributed guide rods 28 are fixedly mounted on the outer ring of the support seat 212; the swing drive assembly also includes a guide cylinder 26 and a rotation drive assembly, the guide cylinder 26 is rotatably mounted on the top surface of the turntable 21 and located on the outer ring of the support seat 212, a guide inclined groove 27 is provided on the side wall of the guide cylinder 26 for sliding engagement with the guide rod 28, and the rotation drive assembly can drive the guide cylinder 26 to rotate when the turntable 21 rotates;

[0050] The rotary drive assembly includes an inner gear ring 23, a gear 24 and an outer gear ring 25. The inner gear ring 23 is arranged on the outer ring of the upper end of the rotating disk 21, and a plurality of support rods 22 are fixedly installed on the bottom surface of the inner gear ring 23. The bottom ends of the plurality of support rods 22 are fixedly installed on the bottom surface of the water collecting tank 11.

The gear 24 is rotatably installed on the outer ring of the top surface of the rotating disk 21, and the gear 24 is meshed and transmission-connected between the inner gear ring 23 and the outer gear ring 25.

[0051] When the turntable 21 rotates, the turntable 21 drives a plurality of bases 210 thereon to perform circular motion, thereby driving a plurality of fabrics to perform circular motion synchronously. At the same time, the turntable 21 drives the gear 24 to move along the inner ring of the internal gear ring 23. At this time, the internal gear ring 23 meshes with and drives the gear 24 to rotate, and the gear 24 meshes with and drives the external gear ring 25 to rotate, so that the external gear ring 25 drives the guide cylinder 26 to rotate, thereby causing the guide inclined groove 27 on the side wall of the guide cylinder 26 to rotate and move relative to the guide rod 28. Among them, the guide inclined groove 27 is composed of two symmetrically arranged arc-shaped inclined grooves, and the two guide rods 28 are respectively movably clamped in the two arc-shaped inclined grooves. When the guide inclined groove 27 rotates and moves relative to the guide rod 28, the two guide rods 28 reciprocate up and down along the two arc-shaped inclined grooves, thereby driving the support seat 212 and the support shaft 29 to reciprocate left and right, and then the support shaft 29 drives the substrate 31 and the fabric to reciprocate, so as to perform a dynamic waterproof test on the fabric;

[0052] When a static waterproof test needs to be performed on the fabric, the turntable 21 is kept stationary, and then the substrate 31 is manually rotated, so that the substrate 31 drives the support seat 212 to rotate through the support shaft 29, so that the support seat 212 drives the guide rod 28 to rotate and move in the guide inclined groove 27, so as to adjust the inclination angle of the substrate 31 through the cooperation of the guide inclined groove 27 and the guide rod 28, so that the fabric can perform a static waterproof test on the substrate 31 at different angles.

[0053] Furthermore, the guide cylinder 26 includes a lower guide sleeve 261 and an upper guide sleeve 262. A lower connecting ring 263 is fixedly installed on the outer circle of the lower guide sleeve 261, and an upper connecting ring 265 is fixedly installed on the outer circle of the upper guide sleeve 262. The lower connecting ring 263 and the upper connecting ring 265 are fixedly connected by a connecting rod 264. Arc-shaped guide inclined surfaces are provided on the top surface of the lower guide sleeve 261 and the bottom surface of the upper guide sleeve 262. The guide inclined groove 27 is formed by surrounding the arc-shaped guide inclined surfaces between the lower guide sleeve 261 and the upper guide sleeve 262; the guide inclined groove 27 is formed by surrounding the lower guide sleeve 261 and the upper guide sleeve 262 connected to each other, so that the setting of the guide inclined groove 27 is more convenient.

[0054] Embodiment 4

[0055] Please refer to Figures 1 - 4 As shown, the difference between this embodiment and the above embodiment is that a water blocking mechanism 4 capable of blocking the spray head 5 is further installed on the test machine body 1. The water blocking mechanism 4 includes a funnel 41 and a diversion pipe 42. The diversion pipe 42 is rotatably installed on the inner side wall of the test machine body 1. An inclined pipe capable of extending below the spray head 5 is provided at the top end of the diversion pipe 42, and a funnel 41 is connected and installed at the top end of the diversion pipe 42. The bottom end of the diversion pipe 42 extends into the water collecting tank 11;

[0056] Among them, when conducting a waterproof test on the fabric, the water pressure fluctuates greatly when the sprinkler head 5 is opened and closed, thereby causing a large fluctuation in the amount of spray water, which is easy to affect the test accuracy. By providing the funnel 41 and the guide tube 42, the funnel 41 can be rotated and moved to the bottom of the sprinkler head 5 before the sprinkler head 5 is opened, so as to block and receive the water sprayed from the sprinkler head 5 to prevent the spray water from directly spraying onto the fabric. At the same time, the guide tube 42 guides the water to the sump 11, and the funnel 41 is rotated and moved away after the water flow in the sprinkler head 5 is stabilized; accordingly, before the spraying is finished, the funnel 41 is first rotated and moved to the bottom of the sprinkler head 5 to block and receive the water sprayed from the sprinkler head 5, and then the sprinkler head 5 is closed; through the cooperation of the funnel 41 and the guide tube 42, the spray water flow is more stable when the fabric is subjected to a waterproof test, which is beneficial to improving the test accuracy.

[0057] Furthermore, a fixing plate 43 is fixedly installed on the inner side wall of the testing machine body 1, and the guide tube 42 is rotatably installed on the fixing plate 43. A positioning plate 44 located below the fixing plate 43 is fixedly installed on the guide tube 42, and a support plate 45 is fixedly installed on the bottom surface of the positioning plate 44, and a pin 47 is slidably inserted on the support plate 45; a pull handle 48 is fixedly installed on the bottom end of the pin 47, and the top end of the pin 47 is movably extended to the top of the positioning plate 44, and a limit plate 410 abutting against the bottom surface of the positioning plate 44 is fixedly installed on the upper end of the pin 47, and the outer ring of the pin 47 is sleeved with a spring 49 abutting between the limit plate 410 and the support plate 45, and a pin hole 46 that can be inserted with the top end of the pin 47 is opened on the fixing plate 43;

[0058] Among them, the pin shaft 47 is upwardly inserted into the pin hole 46 on the fixing plate 43 under the elastic force of the spring 49, so that the positioning plate 44 and the fixing plate 43 are pinned and fixed by the pin shaft 47 and the pin hole 46, thereby limiting and locking the guide tube 42 to improve the installation stability of the guide tube 42 and the funnel 41, and ensure that the funnel 41 is exactly located below the sprinkler head 5. When the funnel 41 needs to be rotated away, the pin shaft 47 is first pulled downward by the pull handle 48 to pull the top end of the pin shaft 47 out of the pin hole 46 on the fixing plate 43 to release the lock between the positioning plate 44 and the fixing plate 43, and then the guide tube 42 can be rotated to rotate the funnel 41 away.

[0059] Embodiment 5

[0060] See also Figures 1 - 8 As shown, this embodiment discloses a test method for developing windproof and breathable jacket fabrics, which is used to test the waterproof performance of jacket fabrics. The specific steps are as follows:

[0061] Before the test, first measure the weight of the unused dry absorbent cotton 32 with a weighing instrument, and then position and install the absorbent cotton 32 and the fabric to be tested on the substrate 31 through the positioning component, and the absorbent cotton 32 is hermetically arranged on the back of the fabric to be tested;

[0062] After that, water is sprayed downward through the spray head 5, and at the same time, the motor drives the turntable 21 to rotate, so that the turntable 21 drives the substrate 31 and the fabric thereon to perform a circular motion. At the same time, the swing drive component drives the support shaft 29 to swing reciprocally, so that the support shaft 29 drives the substrate 31 and the fabric to swing reciprocally, so that the fabric undergoes a water spray test during the circular motion and the swinging process;

[0063] After the water spray test is completed, turn off the spray head 5 and the motor, remove the fabric and the absorbent cotton 32, and measure the weight of the absorbent cotton 32 again with a weighing instrument. The difference in the weight of the absorbent cotton 32 measured before and after is the amount of water that has penetrated through the fabric during the water spray test. Therefore, the waterproof performance of the fabric can be judged based on the measured water penetration amount.
