Description

Technical Field

[0001] This utility model relates to the field of textile testing technology, specifically a comprehensive testing device for the waterproof and breathable properties of textiles. Background Technology

[0002] Textiles are products made from textile fibers through processing and weaving. China is one of the earliest countries in the world to produce textiles. Textile fabrics are divided into two main categories: woven fabrics and knitted fabrics. Industrial textiles have a wide range of applications and many varieties, such as tarpaulins, filter cloths, and roadbed fabrics. The waterproof performance of textile fabrics determines their uses. Therefore, it is necessary to test the waterproof and breathable performance of textile fabrics before they leave the factory to confirm their waterproof effect.

[0003] In existing comprehensive testing devices for the waterproof and breathable properties of textiles, the height of the funnel directly affects the hydrostatic pressure of water sprayed onto the textile surface. Different funnel heights can simulate rainfall of different intensities (such as light rain and heavy rain). However, the funnel is usually fixed to the main body of the device, and different devices need to be replaced when simulating different rainfall environments, which increases the purchase and maintenance costs of the equipment. In addition, the bottom of the funnel usually sprays water onto the textile surface through a nozzle, but the funnel does not have a mechanism to control the water output, and cannot adjust the test water volume according to different fabric thicknesses, which reduces the accuracy of the test results. Utility Model Content

[0004] The purpose of this invention is to provide a comprehensive testing device for the waterproof and breathable properties of textiles, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a comprehensive testing device for the waterproof and breathable properties of textiles, comprising:

[0006] A fixed frame, the top of which is fixedly connected to a connecting plate, and the bottom of which is fixedly connected to a test platform and a water collection tank;

[0007] A transmission assembly is disposed on the outside of the connecting plate, a transmission rod is disposed on the inside of the transmission assembly, and two sets of lifting assemblies are symmetrically disposed on the outside of the transmission rod.

[0008] A connecting component is disposed on the outside of the lifting component, and a fixing seat is provided on the outside of the connecting component;

[0009] The funnel is fixed to the outside of the fixed base, and the fixed component is provided on the outside of the transmission component;

[0010] A spray cap is threaded to the bottom end of the funnel. An adjustment component is provided on the inner side of the spray cap, and a positioning component is provided on the outer side of the adjustment component.

[0011] A sensor is disposed on the outside of the test stand, a display is disposed on one side of the mounting bracket, and a retaining ring for fixing the test sample is rotatably connected to the outside of the test stand.

[0012] Preferably, the transmission assembly includes a throttle that rotates on the top of the connecting plate, one end of the throttle is fixedly connected to a first bevel gear, the outer side of the first bevel gear is meshed with a second bevel gear, and the inner wall of the second bevel gear is fixedly connected to the outer side of the transmission rod.

[0013] Preferably, the lifting assembly includes a first rotating rod fixed to the outside of the transmission rod, and a second rotating rod rotatably connected to the other end of the first rotating rod.

[0014] Preferably, the connecting assembly includes a connecting seat that rotates at one end of the second rotating rod, a guide groove is slidably connected to the outer side of the connecting seat, and the outer side of the connecting seat is fixedly connected to one side of the fixed seat.

[0015] Preferably, the fixing component includes a positioning block fixed to the outside of the throttle, and the top of the connecting plate is provided with a plurality of threaded grooves in an annular shape. The positioning block is connected to the threaded grooves by bolts.

[0016] Preferably, the adjusting assembly includes multiple sliders that slide on the inner wall of the spray cover, an adjusting plate is fixedly connected to the outer side of the multiple sliders, and a water outlet hole is formed through the inner wall of the adjusting plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention uses a transmission rod to drive the first rotating rod to rotate. As the rotation angle changes, the other end of the first rotating rod changes its connection angle with the second rotating rod and moves vertically. They gradually form a folded state, causing the connecting seat to slide downwards along the guide groove, changing the height of the funnel. This allows for the simulation of rainfall of different intensities without the need to replace different devices for testing, reducing the purchase and maintenance costs of the equipment. By rotating the spray cover, when the water outlet on the adjustment plate is not on the same vertical line as the slot of the spray cover, the adjustment plate will block the slot of the spray cover, thereby reducing the water output. This allows for flexible adjustment according to testing needs, improving the accuracy of the test results. Attached Figure Description

[0026] 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.

[0027] Please see Figure 1-5As shown, a comprehensive testing device for the waterproof and breathable properties of textiles includes a fixed frame 1, a connecting plate 2 fixedly connected to the top of the fixed frame 1, a test platform 3 and a water collection tank 17 fixedly connected to the bottom of the fixed frame 1, the water collection tank 17 is used to collect wastewater generated during the test, and a drain pipe is provided at the bottom of the tank to discharge the wastewater; a transmission component 6 is provided on the outside of the connecting plate 2, a transmission rod 7 is provided on the inside of the transmission component 6, and two sets of lifting components 8 are symmetrically arranged on the outside of the transmission rod 7; a connecting component 9 is provided on the outside of the lifting components 8, and a fixed seat 10 is provided on the outside of the connecting component 9; a funnel 11 is fixed on the outside of the fixed seat 10, and the funnel 11 uses its conical structure to evenly gather water flow and guide it to the surface of the textile, simulating a real rainfall scenario and ensuring that the test conditions are consistent with the actual use environment; a fixed component 12 is provided on the outside of the transmission component 6.

[0028] The spray cover 13 is threaded to the bottom of the funnel 11. An adjustment component 14 is provided on the inner side of the spray cover 13, and a positioning component 15 is provided on the outer side of the adjustment component 14.

[0029] Sensor 4 is located on the outside of test platform 3. During testing, the textile is fixed to its outside. When the funnel 11 sprays water onto the textile, if water seepage occurs on the surface of the textile, sensor 4 can detect the change in humidity or water penetration and accurately record the seepage time or amount, providing data support for waterproof performance evaluation. This is existing technology and will not be elaborated on here. A display 5 is set on one side of the fixing frame 1 and is connected to sensor 4 via a signal to display the data obtained by sensor 4, which is convenient for staff to view and record. A retaining ring 16 for fixing the test item is rotatably connected to the outside of test platform 3 to fix the textile to be tested to the outside of test platform 3.

[0030] The transmission assembly 6 includes a throttle 61 that rotates on the top of the connecting plate 2 to facilitate driving the first bevel gear 62 to rotate; one end of the throttle 61 is fixedly connected to the first bevel gear 62 to transmit the kinetic energy when the throttle 61 rotates; the outer side of the first bevel gear 62 is meshed with a second bevel gear 63, the inner wall of the second bevel gear 63 is fixedly connected to the outer side of the transmission rod 7, and the second bevel gear 63 can drive the transmission rod 7 to rotate synchronously.

[0031] The lifting assembly 8 includes a first rotating rod 81 fixed to the outside of the transmission rod 7. The other end of the first rotating rod 81 is rotatably connected to a second rotating rod 82. As one end of the first rotating rod 81 rotates with the transmission rod 7, the other end changes the angle of connection with the second rotating rod 82 as the rotation angle changes, and moves in the vertical direction. They gradually form a folded or unfolded state, driving the funnel 11 to complete the corresponding height adjustment.

[0032] The connecting assembly 9 includes a connecting seat 91 that rotates at one end of the second rotating rod 82. A guide groove 92 is slidably connected to the outer side of the connecting seat 91. The outer side of the connecting seat 91 is fixedly connected to one side of the fixed seat 10. When the connecting seat 91 moves, it slides along the inner side of the guide groove 92. The guide groove 92 restricts the movement path of the connecting seat 91, so that the funnel 11 moves along a vertical trajectory during adjustment.

[0033] The fixing component 12 includes a positioning block 121 fixed to the outside of the throttle 61. The top of the connecting plate 2 has a plurality of threaded grooves 122. The positioning block 121 and the threaded grooves 122 are connected by bolts. After the throttle 61 is adjusted, the bolts are screwed into the positioning block 121 and the threaded grooves 122 below it to form a connection, which can fix the throttle 61 and prevent it from shifting.

[0034] The adjustment assembly 14 includes multiple sliders 141 that slide on the inner wall of the spray cover 13. An adjustment plate 142 is fixedly connected to the outer side of the multiple sliders 141. A water outlet 143 is opened through the inner wall of the adjustment plate 142. A slot with the same position and diameter as the water outlet 143 is opened at the bottom of the spray cover 13. When the slot of the spray cover 13 and the water outlet 143 are not on the same vertical line, the adjustment plate 142 will block the slot of the spray cover 13, thereby adjusting the water output during the test.

[0035] The positioning assembly 15 includes a fixing block 151 fixed to the top of the adjusting plate 142. A positioning seat 152 is fixedly connected to the bottom inner wall of the funnel 11. The outer side of the fixing block 151 is engaged with the inner side of the positioning seat 152. When the spray cover 13 rotates along the bottom of the funnel 11, the spray cover 13 will move up and down because they are connected by threads. As the adjusting plate 142 moves along with it, the adjusting plate 142 cannot rotate laterally because the fixing block 151 is engaged with the inner side of the positioning seat 152. Instead, it will slide vertically along the inner side of the positioning seat 152 with the fixing block 151.

[0036] Working principle: When adjusting the height of the funnel 11, first unscrew the bolts inside the positioning block 121. Then, rotate the handle 61 to make the first bevel gear 62 rotate with the second bevel gear 63. At the same time, the transmission rod 7 drives one end of the first rotating rod 81 to rotate around its center. As the rotation angle changes, the other end of the first rotating rod 81 changes the angle of connection with the second rotating rod 82 and moves vertically. They gradually form a folded state, causing the connecting seat 91 to slide downward along the guide groove 92, thus changing the height of the funnel 11. After adjustment, water is injected into the funnel 11. Then, the spray cover 13 can be rotated according to the test requirements. The spray cover 13 rotates along the bottom of the funnel 11. However, since the fixed block 151 is limited by the positioning seat 152, the adjusting plate 142 will not rotate. It will only move vertically along with the spray cover 13. When the water outlet 143 on the adjusting plate 142 is not on the same vertical line as the hole groove of the spray cover 13, the adjusting plate 142 will block the hole groove of the spray cover 13, thereby reducing the water output. This allows for flexible adjustment according to the test requirements.
