Description

Technical Field

[0001] This utility model relates to the technical field of fabric testing equipment, specifically a device for testing the waterproof performance of nylon fabrics. Background Technology

[0002] In modern society, thanks to scientific advancements and improved living standards, a vast array of textiles with superior performance, diverse designs, and vibrant colors are in high demand. These textiles not only provide functions such as covering, protecting, warmth, and heat protection, but also serve decorative and aesthetic purposes, and as a form of identification. Traditional clothing fabrics are suitable for most wearing scenarios. However, for clothing with specific needs, specialized fabrics become the priority. For example, comfort is paramount for loungewear, while sportswear, increasingly integrated into our daily lives, requires breathability, quick-drying properties, sun protection in sunny weather, windproofing in windy conditions, and waterproofing in heavy rain. The needs of clothing vary depending on the scenario. The emergence of new textile materials has opened up new avenues for the industry's development. Nylon 6 water-repellent yarn, a new type of textile material, produces nylon fabrics that can be used in sportswear.

[0003] Patent CN219009420U discloses a quality inspection device for knitted fabrics, including an inspection box. A fixed frame is fixed to the right side of the inner cavity of the inspection box, and a movable frame is movably connected to the inner cavity of the inspection box. A tension sensor is arranged on the left side of the movable frame, and a traction component is arranged on the left side of the tension sensor. The inner cavities of the fixed frame and the movable frame are respectively rotatably connected to a first rotating shaft and a second rotating shaft via bearings. A winding drum is fixed to the surface of both the first and second rotating shafts, and knitted fabric is wound around the surface of the winding drum. Limiting components are provided on the surfaces of both the first and second rotating shafts. This invention winds the knitted fabric around the surface of the winding drum, then rotates the first and second rotating shafts to rotate the winding drum, and then the winding drum winds up the knitted fabric. The wound knitted fabric gradually tightens under the rotation of the winding drum, and its own friction ensures the tension of the knitted fabric, preventing it from loosening and slipping off the surface of the winding drum.

[0004] Currently, traditional waterproof performance testing equipment for nylon fabrics requires testing the waterproof effect of the fabric after production to determine its waterproof performance. However, common waterproof testing structures are relatively simple and reduce testing efficiency, thus affecting product quality. Utility Model Content

However, the common waterproof testing structure is relatively simple and reduces the testing efficiency, thus affecting the quality of the product.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof performance testing device for nylon fabric, comprising a workbench, a support leg at the lower end of the workbench, a bracket on the upper left side of the workbench, a unwinding roller detachably connected to the upper end of the bracket, a work box fixedly connected to the upper end of the workbench, a spraying mechanism fixedly connected to the upper end of the work box, a mounting frame fixedly connected to the front end of the work box, a guiding mechanism fixedly connected to the inner side of the mounting frame, a limiting component fixedly connected to one side of the upper end of the workbench, a take-up roller fixedly connected to the inner side of the limiting component, a tensioning roller assembly rotatably connected to one side of the inner wall of the work box, and a traction roller fixedly connected to one side of the work box;

[0007] The spraying mechanism includes a water storage tank, the lower end of which is fixedly connected to the upper end of the working box. A drain pipe is provided at the front end of the water storage tank, and a water inlet pipe is provided at the upper end of the water storage tank. An activated carbon layer is fixedly connected to the inner wall of the water storage tank, and a filter screen is fixedly connected to one side of the activated carbon layer. A return pipe is connected to the rear end of the water storage tank, and a water pump is fixedly connected to the middle of the return pipe. A second water pump is fixedly connected to one side of the water storage tank, and a liquid delivery pipe runs through the middle of the second water pump. A spray head is fixedly connected to the lower end of the liquid delivery pipe.

[0008] Preferably, the upper end of the support leg is fixedly connected to the lower end of the workbench, and the lower end of the bracket is fixedly connected to one side of the upper end of the workbench.

[0013] Preferably, the number of gear one, chain and gear two is set in two sets.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The spray mechanism enables the equipment to perform comprehensive waterproof testing on nylon fabrics. Within the spray mechanism, the water tank not only serves as a water storage container but also performs preliminary water purification through a built-in activated carbon layer and filter screen, ensuring the sprayed water is pure and free of impurities, reducing interference with fabric testing results. A water pump, in conjunction with a return pipe, recycles used spray water back into the water tank, saving water resources and improving the equipment's environmental performance. Eight spray heads are symmetrically distributed on both sides of the delivery pipe, providing a wider spray range and evenly covering the entire nylon fabric surface, ensuring comprehensive and accurate waterproof testing. Furthermore, the number of spray heads can be adjusted according to actual testing needs, enhancing the equipment's flexibility and adaptability.

[0016] 2. The guiding mechanism allows the equipment to drive the guide roller to rotate via gear one, chain, and gear two, thereby achieving smooth conveying of nylon fabric. This not only simplifies the structure of the conveying mechanism and improves the operational stability of the equipment, but also ensures the tension and positional accuracy of the fabric during conveying through the precision of gear transmission, providing strong support for subsequent waterproof testing. At the same time, it improves the load-bearing capacity and stability during transportation, maintaining a stable conveying effect even when handling nylon fabrics with larger widths or heavier weights.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 and Figure 4 This utility model provides a technical solution: a waterproof performance testing device for nylon fabric, including a workbench 1, a support leg 2 at the lower end of the workbench 1, a bracket 3 on the upper left side of the workbench 1, a unwinding roller 4 detachably connected to the upper end of the bracket 3, a work box 5 fixedly connected to the upper end of the workbench 1, a spraying mechanism 6 fixedly connected to the upper end of the work box 5, a mounting frame 7 fixedly connected to the front end of the work box 5, a guiding mechanism 8 fixedly connected to the inner side of the mounting frame 7, a limiting component 9 fixedly connected to one side of the upper end of the workbench 1, a take-up roller 10 fixedly connected to the inner side of the limiting component 9, a tensioning roller group 11 rotatably connected to one side of the inner wall of the work box 5, a traction roller 12 fixedly connected to one side of the work box 5, and a spraying mechanism. 6 includes a water storage tank 61, the lower end of which is fixedly connected to the upper end of the work box 5. A drain pipe 62 is provided at the front end of the water storage tank 61, and a water inlet pipe 63 is provided at the upper end of the water storage tank 61. An activated carbon layer 64 is fixedly connected to the inner wall of the water storage tank 61, and a filter screen 65 is fixedly connected to one side of the activated carbon layer 64. A return pipe 66 is connected to the rear end of the water storage tank 61. A water pump 67 is fixedly connected to the middle of the return pipe 66, and a water pump 68 is fixedly connected to one side of the water storage tank 61. A liquid delivery pipe 69 passes through the middle of the water pump 68, and a spray head 610 is fixedly connected to the lower end of the liquid delivery pipe 69. The upper end of the support leg 2 is fixedly connected to the lower end of the worktable 1, and the lower end of the bracket 3 is fixedly connected to one side of the upper end of the worktable 1.

[0024] Driven by water pump 68, the spray mechanism 6 delivers the test liquid from the water storage tank 61 to the spray head 610 via the liquid delivery pipe 69. The spray heads 610 are symmetrically distributed on both sides, ensuring that the test liquid can evenly and extensively cover the entire surface of the nylon fabric, thereby achieving comprehensive and accurate waterproof testing. At the same time, the number of spray heads 610 and the spray intensity can be adjusted according to actual testing needs to adapt to nylon fabrics of different specifications and requirements. During the testing process, after the test liquid comes into full contact with the fabric, some liquid will penetrate into the fabric, while the excess liquid will be pumped back to the water storage tank 61 by water pump 67 after being filtered through the filter screen 65 and activated carbon layer 64 via the return pipe 66 at the bottom of the working box 5, thus realizing the recycling of the test liquid, which not only saves resources but also reduces operating costs.

[0025] Please see Figure 2 In order to quickly spray the water in the water storage tank, the front end of the water storage tank 61 is connected to the rear end of the drain pipe 62, the upper end of the water storage tank 61 is connected to the lower end of the water inlet pipe 63, and the number of spray heads 610 is set to eight, all of which are symmetrically arranged on both sides of the liquid delivery pipe 69.

[0026] After the nylon fabric passes through the spray test, it continues to be conveyed along the guide roller 86 to the take-up roller 10. Through the fixing of the limiting member 9 and the adjustment of the tension roller group 11, the fabric is ensured to remain flat and tight during the winding process. Finally, the nylon fabric that has completed the test is neatly wound on the take-up roller 10 for subsequent processing and analysis.

[0027] Please see Figure 3 To quickly fix the fabric onto the take-up roller, the guiding mechanism 8 includes a motor 81. One end of the motor 81 is bolted to one end of the mounting frame 7. The output shaft of the motor 81 is equipped with a gear 82. A chain 83 is provided on the outer wall of the gear 82. A gear 84 is meshed with one side of the inner wall of the chain 83. A rotating rod 85 is inserted into the middle of the gear 84. A guide roller 86 is sleeved on the outer wall of the rotating rod 85. Bearing seats 87 are rotatably connected to both sides of the rotating rod 85. The output shaft of the motor 81 is connected to one side of the gear 82. The outer wall of the gear 82 is meshed with the inner wall of the chain 83. There are two sets of gears 82, chain 83 and gear 84.

[0028] By winding the nylon fabric onto the unwinding roller 4 and initially tractioning it with the traction roller 12, the fabric smoothly enters the working box 5. As the fabric continues to be fed, the motor 81 starts, and its output shaft drives the gear 82 to rotate. Then, through the transmission of the chain 83, the gear 84 and the connected rotating rod 85 and guide roller 86 rotate synchronously. The rotation of the guide roller 86 not only provides a stable conveying path for the fabric, but also ensures the tension and positional accuracy of the fabric during the conveying process through the friction of its surface, avoiding the impact of fabric slack or deviation on the spraying effect.

[0029] Working principle: First, the nylon fabric is wound onto the unwinding roller 4, and then initially pulled by the traction roller 12, so that the fabric enters the working box 5 smoothly. As the fabric continues to be fed, the motor 81 starts, and its output shaft drives the gear 1 82 to rotate. Then, through the transmission of the chain 83, the gear 2 84 and the connected rotating rod 85 and guide roller 86 are driven to rotate synchronously. The rotation of the guide roller 86 not only provides a stable conveying path for the fabric, but also ensures the tension and positional accuracy of the fabric during the conveying process through the friction of its surface, avoiding the impact of fabric slack or deviation on the spraying effect.

[0030] Then, driven by water pump 68, the spray mechanism 6 delivers the test liquid from the storage tank 61 to the spray head 610 via the delivery pipe 69. The spray heads 610 are symmetrically distributed on both sides, ensuring that the test liquid can evenly and extensively cover the entire surface of the nylon fabric, thereby achieving comprehensive and accurate waterproof testing. At the same time, the number and spray intensity of the spray heads 610 can be adjusted according to actual testing needs to adapt to nylon fabrics of different specifications and requirements. During the testing process, after the test liquid comes into full contact with the fabric, some liquid will penetrate into the fabric, while the excess liquid will be pumped back to the storage tank 61 by water pump 67 after being filtered through the filter screen 65 and activated carbon layer 64 via the return pipe 66 at the bottom of the working chamber 5. In the water tank 61, the detection liquid is recycled, which not only saves resources but also reduces operating costs. After the nylon fabric is sprayed for testing, it continues to be conveyed along the guide roller 86 to the take-up roller 10. Through the fixing of the limiting member 9 and the adjustment of the tension roller group 11, the fabric is ensured to remain flat and tight during the winding process. Finally, the nylon fabric that has completed the test is neatly wound on the take-up roller 10, which facilitates subsequent processing and analysis. This not only improves the testing efficiency and accuracy but also reduces operating costs and maintenance difficulty. At the same time, it has the characteristics of compact structure and simple operation. The above is the working process of the entire device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
