Description

Technical Field

[0001] This utility model relates to the field of testing device technology, and in particular to an online testing device for the waterproof performance of fabrics. Background Technology

[0002] Fabric waterproof performance testing is a key technology for evaluating a fabric's ability to resist water penetration. It is widely used in outdoor clothing, bags, tents and other fields. Water is sprayed onto the fabric surface through a spraying device (water temperature 20±2℃, water pressure about 0.2MPa), and the state of the water droplets on the fabric surface (spreading, rolling or penetrating) is observed. Usually, a pressure roller is used to squeeze the fabric after spraying, and the pressure is detected by a pressure detector equipped on the pressure roller to determine the water penetration.

[0003] Regarding the aforementioned technologies, the existing testing devices have the following drawbacks: during the fabric transfer and transportation process, static electricity is generated due to friction. During the spray test, the charged fabric may attract tiny water droplets from the air, creating a false "water repellency" phenomenon, which affects the accuracy of the test. Therefore, this utility model provides an online testing device for the waterproof performance of fabrics. Utility Model Content

[0019] Example 1: Reference Figure 1-4The illustrated online fabric waterproof performance testing device includes a controller and a power supply. The controller controls electrical components (such as a motor and a telescopic hydraulic cylinder), while the power supply provides power. The device includes a support frame 1, which serves as the foundational support structure, providing a stable mounting platform for other components and ensuring the device remains stable during operation, preventing vibrations from affecting the accuracy of the test results. Three fixed brackets 8 are fixedly connected to the top of the support frame 1, securing hydraulic push rods 9 and ensuring their stable position during operation. This allows for precise control of the lifting frame 10's lifting motion. Hydraulic push rods 9 are threaded through the inner sides of each fixed bracket 8. Through hydraulic transmission, the hydraulic push rods 9 precisely and stably control the lifting frame 10's height, allowing for flexible adjustment of the lifting frame 10's height to meet the spatial requirements of different testing stages. The output end of the hydraulic push rod 9 is fixedly connected to the lifting frame 10, which houses key components such as antistatic and water-pumping components. Driven by the hydraulic push rods 9, these components are raised and lowered, enabling them to process and test the fabric on the conveyor device 2 at appropriate positions. A conveying device 2 is installed inside the support frame 1. The conveying device 2 is responsible for transporting the fabric, allowing it to pass through the detection area along a set route and speed, ensuring continuous and stable movement of the fabric during the detection process, and enabling continuous online detection of the fabric. A spray head 6 is installed above the conveying device 2. The spray head 6 evenly sprays a certain amount of water onto the fabric surface to simulate a humid environment such as rain, providing actual testing conditions for the fabric's waterproof performance. The waterproof performance is judged by observing the fabric's behavior after spraying. An antistatic component is installed inside the lifting frame 10 near the spray head 6; a water pumping component is installed inside the lifting frame 10 in the middle. The antistatic component includes a metal core shaft 26 rotatably connected to the inner wall of the corresponding lifting frame 10. The metal core shaft 26 acts as a conductive component, conducting static electricity and providing a conductive path to eliminate static electricity on the fabric surface. A conductive silicone layer 12 is fixedly connected to the outside of the metal core shaft 26. The conductive silicone layer 12 has good conductivity and flexibility, ensuring sufficient contact with the fabric surface to effectively absorb static electricity without damaging the fabric surface. A rotating conductive shaft 22 is fixedly connected to the side of the metal core shaft 26. The rotating conductive shaft 22 passes through the lifting frame 10 and is used to conduct static electricity conducted by the metal core shaft 26, while maintaining a stable conductive connection when the metal core shaft 26 rotates. A conductive ring 23 is rotatably connected to the outside of the rotating conductive shaft 22. The conductive ring 23 can maintain good electrical contact with the rotating conductive shaft 22, ensuring that static electricity is smoothly discharged even when the rotating conductive shaft 22 rotates, and the static elimination effect will not be affected by poor contact. An ion generator 19 is provided on the outside of the support frame 1. The ion generator 19 can generate ions with positive and negative charges to neutralize the static charge on the fabric surface and eliminate static electricity at its source.A wire 17 is fixedly connected to the output end of the ion generator 19. The wire 17 is connected to the conductive ring 23. The wire 17 is responsible for conducting the ions generated by the ion generator 19 to the conductive ring 23, and then eliminating static electricity on the fabric by rotating the conductive shaft 22, the metal core shaft 26, and the conductive silicone layer 12. A motor 11 is fixedly connected to the outside of the lifting frame 10. The output end of the motor 11 passes through the lifting frame 10 and is fixedly connected to the metal core shaft 26. The motor 11 provides rotational power to the metal core shaft 26, so that the conductive silicone layer 12 can continuously contact the fabric surface, ensuring the continuity and effectiveness of the static elimination process, completely eliminating static electricity on the fabric surface, and avoiding static electricity affecting the waterproof performance test results of the fabric. The water pumping assembly includes a fixed cylinder 21 fixedly connected to the inner wall side of the corresponding lifting frame 10. The fixed cylinder 21 is used to install and fix components such as the water pump head 5 and the negative pressure pipe 20, providing stable structural support for the water pumping assembly and ensuring stable operation of the water pumping process. A slot 24 is provided on the inner side of the fixed cylinder 21, providing storage space for water drawn by the suction head 5, allowing the water to be temporarily stored for subsequent processing. Multiple holes 25 are provided on the inner wall of the slot 24, allowing water drawn by the suction head 5 to smoothly enter the slot 24 for collection and storage. A negative pressure pipe 20 is fixedly connected to the inner wall of the slot 24. The negative pressure pipe 20 generates negative pressure suction to provide pumping power for the suction head 5, enabling it to quickly and effectively extract moisture from the fabric surface. A suction head 5, compatible with the holes 25, is fixedly connected to the outer side of the negative pressure pipe 20. The suction head 5 directly contacts the fabric surface, and under the action of the negative pressure pipe 20, promptly extracts the moisture from the fabric surface after spray testing, preventing residual moisture from affecting subsequent testing or causing unnecessary wetting of the fabric, ensuring the accuracy of the testing process and the integrity of the fabric.

[0020] Example 2: Reference Figure 1-4Based on the same concept as in Embodiment 1 above, this embodiment also proposes that a water pump 27 is fixedly connected to the outer side of the support frame 1. The function of the water pump 27 is to generate suction by extraction. Its output end is connected to the negative pressure pipe 20, which can extract air or liquid in the area connected by the negative pressure pipe 20 to form a negative pressure environment, which is convenient for adsorbing and extracting specific substances or performing related operations. A lower pressure roller 18 is fixedly connected to the inner wall side of the lifting frame 10 away from the spray head 6. The lower pressure roller 18 is used to apply pressure to objects passing under it, so as to flatten them or achieve a specific compaction effect. Multiple pressure sensors 14 are set on the outer side of the lower pressure roller 18. The pressure sensors 14 can monitor the magnitude of the pressure applied by the lower pressure roller 18 in real time and feed back the pressure data so as to adjust the pressure according to the needs and ensure the quality and stability of operation. An inclined plate 13 is fixedly connected to the outer side of the fixed frame 8 away from the spray head 6. The inclined plate 13 provides the installation angle and position for the camera 16 and the ring light 15, which is convenient for observation and shooting of specific areas. A camera 16 is installed on the side of the inclined plate 13. The camera 16 can monitor and record the equipment's operating status or processing process, facilitating timely detection of problems. A ring-shaped supplementary light 15 is installed on the side of the inclined plate 13. The ring-shaped supplementary light 15 provides sufficient illumination for the camera 16 in low light conditions, ensuring clear visibility of the captured image. A water storage tank 3 is installed on the outer side of the support frame 1. The water storage tank 3 is used to store liquid, providing a liquid source for equipment operation. A water supply pipe 4 is fixedly connected to the output end of the water storage tank 3. The water supply pipe 4 is connected to the spray head 6, and the water supply pipe 4 transports the liquid in the water storage tank 3 to the spray head 6. A water pump is installed at the connection point between the water supply pipe 4 and the water storage tank 3. The water pump provides power for the flow of liquid in the water supply pipe 4, ensuring that the liquid can be stably and continuously delivered to the spray head 6. A support rod 7 is fixedly connected to the outer side of the support frame 1. The support rod 7 supports and fixes the spray head 6, ensuring the stability of the spray head 6 during operation, so that it can accurately spray the target area.

[0021] The working principle of this utility model is as follows: The fabric is placed in the conveyor device 2 for transport. The water tank 3 sprays the fabric through the water pipe 4 and the spray head 6, causing the fabric to move to below the conductive silicone layer 12. The corresponding hydraulic push rod 9, lifting frame 10, metal core shaft 26, and conductive silicone layer 12 are controlled to move downwards, so that the conductive silicone layer 12 is in contact with the fabric. The ion generator 19 is controlled to guide ions through the wire 17, conductive ring 23, and rotating conductive shaft 22. The ions are then guided to the fabric through the metal core shaft 26 and conductive silicone layer 12, eliminating static electricity between fibers and preventing the fibers from adsorbing water droplets and forming an irregular water film. This allows the fabric to be transported to below the fixed cylinder 21. The corresponding hydraulic push rod 9 and lifting frame 10 are controlled to move downwards, and the water pump 27, negative pressure pipe 20, and water suction head 5 are controlled to suck away the water droplets on the fabric, reducing the impact of the surface water film on subsequent pressure detection. The fabric moves to below the lower pressure roller 18, and the corresponding hydraulic push rod 9 and lifting frame 10 are controlled to move downwards. The lower pressure roller 18 drives the pressure sensor 14 to move downwards, squeezing the fabric. When the pressure sensor 14 detects a sudden drop in pressure (indicating that moisture penetration reduces the fabric's pressure resistance), the PLC controller triggers an alarm, and the camera 16 captures an image of the water droplet contact angle. The PLC controller combines the pressure data and image characteristics to determine the waterproof level.
