[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0034] like Figure 1 , Figure 2 and Fig. 9As shown, the waterproof fabric detection device proposed in this embodiment is arranged on a main machine table 500, and includes a pressure water component 100, a lifting and fixing component 200, a cloth conveying component 300 and a one-way transmission component 400. The pressure water component 100 includes a detection table 101, and a pressure water outlet 104 is provided on the top of the detection table 101. The detection table 101 is fixedly arranged on the main machine table 500; the lifting and fixing component 200 includes a pressing ring 201, and the pressing ring 201 is used to press and fix the waterproof fabric. The lifting and fixing component 200 drives the pressing ring 201 to move. 1 moves up and down, and the pressing ring 201 is located just above the detection table 101; the cloth conveying assembly 300 includes a cloth conveying roller 301, which is rotatably connected to the main machine table 500, and the cloth conveying roller 301 is used to convey the waterproof fabric; the one-way transmission assembly 400 is arranged on the cloth conveying roller 301, and the lifting and fixing assembly 200 drives the cloth conveying roller 301 to rotate through the one-way transmission assembly 400, and the cloth conveying roller 301 starts to rotate when the pressing ring 201 moves upward, and stops rotating when the pressing ring 201 moves downward.

[0035] In this embodiment, the main structure includes a pressure water component 100, a lifting and fixing component 200, a cloth conveying component 300 and a one-way transmission component 400. The pressure water component 100 is arranged on the main machine table 500, and is mainly used to generate pressure water, and the pressure water is applied to the waterproof fabric to detect the waterproof performance of the waterproof fabric against static pressure penetration. The pressure water component 100 includes a detection table 101, and a pressure water outlet 104 is arranged on the top of the detection table 101. When the waterproof fabric is tested, the waterproof fabric is pressed on the top of the detection table 101, and the pressure water generated by the pressure water component 100 contacts the waterproof fabric through the pressure water outlet 104. The waterproof performance of the waterproof fabric against static pressure penetration is judged by observing whether the waterproof fabric leaks.

[0036] The lifting and fixing assembly 200 proposed in this embodiment is arranged on both sides of the main machine table 500, and is mainly used to press and fix the waterproof fabric. The lifting and fixing assembly 200 is provided with a pressing ring 201. When the lifting and fixing assembly 200 is working, it can drive the pressing ring 201 to move up and down. Since the pressing ring 201 is located directly above the detection table 101, when the pressing ring 201 moves downward, it will contact the detection table 101. When the pressing ring 201 contacts the detection table 101, the waterproof fabric is clamped between the pressing ring 201 and the detection table 101. The downward driving force applied by the lifting and fixing assembly 200 to the pressing ring 201 acts on the waterproof fabric and the detection table 101 through the pressing ring 201. At this time, the water pressure in the pressure outlet 104 will all act on the waterproof fabric, and will not be released from the side, thereby ensuring that the waterproof fabric can be subjected to stable static pressure, thereby improving the detection effect of the waterproof fabric.

[0037] The fabric conveying assembly 300 and the one-way transmission assembly 400 proposed in this embodiment are used to convey waterproof fabrics, wherein the fabric conveying assembly 300 includes a fabric conveying roller 301, the fabric conveying roller 301 is rotatably arranged on the main machine table 500, the one-way transmission assembly 400 is arranged on the fabric conveying assembly 300, and the lifting and fixing assembly 200 drives the fabric conveying roller 301 to rotate through the one-way transmission assembly 400; when testing the waterproof fabric, the waterproof fabric is placed on the fabric conveying roller 301, and the lifting and fixing assembly 200 drives the pressing ring 201 to move downward to the position of the testing table 101 to press and fix the waterproof fabric, and at this time the fabric conveying roller 301 remains stationary; after the testing is completed, the lifting and fixing assembly 200 drives the pressing ring 201 to move upward, and at this time the one-way transmission assembly 400 controls the fabric conveying roller 301 to start rotating, and when the fabric conveying roller 301 rotates, it drives the waterproof fabric to move, and the position where the testing is completed is removed from the testing table 101, so that the testing table 101 can test other positions.

[0038] When the lifting and fixing component 200 drives the pressing ring 201 to move downward, it presses and fixes the waterproof fabric to complete the static pressure penetration test. When the lifting and fixing component 200 drives the pressing ring 201 to rise, it releases the waterproof fabric and transfers kinetic energy to the fabric conveying roller 301 through the one-way transmission component 400, thereby driving the fabric conveying roller 301 to rotate and convey the waterproof fabric. As the lifting and fixing component 200 drives the pressing ring 201 to move up and down reciprocatingly, different positions of the waterproof fabric can be detected, thereby improving the detection efficiency, increasing the number of detection samples, and improving the detection effect and accuracy.

[0039] At the same time, since the working state of the cloth conveying roller 301 is mechanically controlled by the lifting and fixing component 200, there is no need to set up a separate control and sensing system for the cloth conveying roller 301, which reduces the overall complexity of the device, saves production and use costs, and has high waterproof performance, and is suitable for working environments with water splashing.

[0040] like Figure 2 , Figure 3 and Figure 5 As shown, the lifting and fixing assembly 200 includes a screw lift 202 and a servo motor 203. The screw lift 202 is provided with a vertical screw 207. The servo motor 203 is connected to the screw lift 202. The servo motor 203 drives the vertical screw 207 to rotate. The pressing ring 201 is provided with a symmetrical lifting connecting arm 205. The lifting connecting arm 205 is provided with a threaded barrel 206. The threaded barrel 206 is meshed with the vertical screw 207.

[0041] In this embodiment, the lifting and fixing assembly 200 includes a pressing ring 201, a screw lift 202 and a servo motor 203, wherein the screw lift 202 and the servo motor 203 are used to drive the lifting and lowering of the pressing ring 201, and a vertical screw 207 is provided on the screw lift 202. When the servo motor 203 is working, it provides power for the screw lift 202, and the screw lift 202 drives the vertical screw 207 to rotate; a symmetrical lifting connecting arm 205 is provided on the pressing ring 201, and a threaded barrel 206 is provided on the lifting connecting arm 205. The threaded barrel 206 is meshed with the vertical screw 207. When the vertical screw 207 rotates, it drives the threaded barrel 206 to rise or fall, thereby realizing the lifting and lowering of the pressing ring 201. The lifting and lowering of the pressing ring 201 can be controlled by changing the rotation direction of the output shaft of the servo motor 203.

[0042] The rise and fall of the pressing ring 201 are controlled by the cooperation of the screw lift 202 and the servo motor 203, with large transmission torque and smooth movement. In addition, when the pressing ring 201 descends to the position of the detection table 101 to press and fix the waterproof fabric, the screw lift 202 and the servo motor 203 can provide continuous torque for the pressing ring 201 to keep the waterproof fabric in close contact with the detection table 101, prevent pressure water from leaking from under the waterproof fabric, and improve the detection effect.

[0043] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a primary transmission gear 209 is fixedly provided on the output shaft of the servo motor 203, a roller support 501 is fixedly provided on the main machine table 500, and the cloth conveying roller 301 is rotatably provided in the roller support 501; the one-way transmission component 400 includes a transmission chain 401, a secondary transmission gear 402 and a ratchet wheel 403, the secondary transmission gear 402 is rotatably provided on the cloth conveying roller 301, the transmission chain 401 is connected to the primary transmission gear 209 and the secondary transmission gear 402, the ratchet wheel 403 is fixedly provided on the cloth conveying roller 301, the secondary transmission gear 402 is provided with an inner ratchet 404, the ratchet wheel 403 is located in the inner ratchet 404, the ratchet wheel 403 is provided with a transmission pawl 405 and an elastic paddle 406, the transmission pawl 405 is meshed with the inner ratchet 404, and the elastic paddle 406 is pressed against the transmission pawl 405.

[0044] In this embodiment, when the servo motor 203 is working, it drives the pressing ring 201 to move up and down through the screw elevator 202. A fixed primary transmission gear 209 is set on the output shaft of the servo motor 203. When the output shaft of the servo motor 203 rotates, it drives the primary transmission gear 209 to rotate synchronously. In addition, a secondary transmission gear 402 is set on the cloth conveying roller 301, and the secondary transmission gear 402 and the primary transmission gear 209 are connected by a transmission chain 401. When the primary transmission gear 209 rotates, the secondary transmission gear 402 is pulled to rotate synchronously through the transmission chain 401, thereby realizing power transmission from the primary transmission gear 209 to the secondary transmission gear 402.

[0045] In this embodiment, a fixed ratchet wheel 403 is provided on the cloth conveying roller 301, an inner ratchet 404 is provided on the secondary transmission gear 402, the ratchet wheel 403 is located in the inner ratchet 404, and a transmission pawl 405 and an elastic paddle 406 are provided on the ratchet wheel 403. The transmission pawl 405 is meshed with the inner ratchet 404, and the elastic paddle 406 is pressed against the transmission pawl 405.

[0046] When the servo motor 203 drives the pressing ring 201 to descend, the servo motor 203 drives the primary transmission gear 209 to rotate, and the primary transmission gear 209 drives the secondary transmission gear 402 to rotate through the transmission chain 401. When the secondary transmission gear 402 rotates, the ratchet wheel 403 overcomes the elastic force of the elastic paddle 406 to press the transmission ratchet 405 down. At this time, the rotational torque of the secondary transmission gear 402 is not transmitted to the ratchet wheel 403, and the secondary transmission gear 402 is in an idling state. The cloth conveying roller 301 remains stationary, and the waterproof fabric stays in place for detection.

[0047] When the servo motor 203 drives the pressing ring 201 to rise, the servo motor 203 reverses, and the primary transmission gear 209 drives the secondary transmission gear 402 to rotate in the opposite direction through the transmission chain 401. When the secondary transmission gear 402 rotates in the opposite direction, it hits the transmission pawl 405, and transmits the rotational torque to the pawl wheel 403 through the transmission pawl 405, thereby driving the cloth conveying roller 301 to rotate. At the same time, the pressing ring 201 rises and gradually leaves the surface of the waterproof fabric, and no longer applies pressure to the waterproof fabric. Therefore, the rotation of the cloth conveying roller 301 can drive the waterproof fabric to move, thereby realizing the transportation of the waterproof fabric, and then automatically changing the detection position, thereby realizing automatic detection of multiple detection positions.

[0048] like Figure 5 As shown, a height limiting block 208 is provided at the top of the vertical screw rod 207 , and the minimum outer diameter of the height limiting block 208 is greater than the maximum outer diameter of the vertical screw rod 207 .

[0049] In this embodiment, when the detection is completed, the pressing ring 201 rises, and the threaded barrel 206 rises along the vertical screw 207. A height limiting block 208 is set at the top of the vertical screw 207 and the minimum outer diameter of the height limiting block 208 is greater than the maximum outer diameter of the vertical screw 207. The threaded barrel 206 is limited to prevent the threaded barrel 206 from falling off the vertical screw 207 when rising, thereby improving the overall safety of the device.

[0050] like Figure 4 As shown, a completely penetrating observation notch 204 is provided on the pressing ring 201 , and the observation notch 204 is symmetrically arranged on the pressing ring 201 .

[0051] In this embodiment, a symmetrical and completely penetrating observation notch 204 is provided on the pressing ring 201. When the waterproof fabric is subjected to static pressure penetration testing, the pressing ring 201 presses and fixes the waterproof fabric, and the detection position of the waterproof fabric can be observed through the observation notch 204. The waterproof performance of the waterproof fabric can be judged by observing whether there is leakage on the surface of the waterproof fabric. In order to increase the significance of the leakage, a small amount of anhydrous copper sulfate can be sprinkled when the pressing ring 201 presses the waterproof fabric according to actual conditions. Once the waterproof fabric leaks, the anhydrous copper sulfate can change color to indicate the leakage position, which is convenient for statistical testing results.

[0052] like Figure 2 , Figure 5 and Figure 6 As shown, the pressure water assembly 100 includes a servo water pump 102 and a water delivery pipe 103. The two ends of the water delivery pipe 103 are respectively connected to the servo water pump 102 and the detection table 101. A pressure water flow channel 105 is provided inside the detection table 101. The pressure water outlet 104 is connected to the pressure water flow channel 105, and the pressure water flow channel 105 is connected to the water delivery pipe 103.

[0053] In this embodiment, the pressure water component 100 includes a servo water pump 102 and a water supply pipe 103. The two ends of the water supply pipe 103 are respectively connected to the servo water pump 102 and the detection table 101. A pressure water flow channel 105 is provided inside the detection table 101. The pressure water outlet 104 is connected to the pressure water flow channel 105. The pressure water flow channel 105 is connected to the water supply pipe 103. When the servo water pump 102 is working, the pressure water is output. The pressure water enters the pressure water flow channel 105 through the water supply pipe 103, and then enters the pressure water outlet 104 and contacts the waterproof fabric, and the waterproof fabric is subjected to static pressure penetration detection.

[0054] like Figure 2 and Fig. 9 As shown, a surrounding edge strip 106 is provided at the edge of the detection table 101 . The edge strip 106 is located directly below the pressing ring 201 , and the projection of the pressing ring 201 on the detection table 101 is located within the edge strip 106 .

[0055] In this embodiment, a surrounding edge strip 106 is provided at the edge of the detection table 101. The edge strip 106 is located directly below the pressing ring 201. The projection of the pressing ring 201 on the detection table 101 is located within the edge strip 106. When the pressing ring 201 descends to the position of the detection table 101, the pressing ring 201 presses the waterproof fabric against the edge strip 106, thereby improving the contact effect between the waterproof fabric and the detection table 101 and avoiding leakage of pressurized water.

[0056] like Figure 1 and Fig. 9 As shown, a fixing plate 107 is fixedly provided on the detection table 101 , and fixing bolts 108 are detachably provided on the fixing plate 107 . The fixing plate 107 is bolted to the host table 500 through the fixing bolts 108 .

[0057] In this embodiment, a fixing plate 107 is fixedly provided on the detection table 101, and a fixing bolt 108 is detachably provided on the fixing plate 107. The fixing plate 107 is bolted to the main machine table 500 through the fixing bolt 108. The pressure applied by the pressing ring 201 to the detection table 101 is transmitted to the main machine table 500 through the fixing plate 107. The fixing bolt 108 firmly connects the fixing plate 107 to the main machine table 500, thereby improving the stability during the waterproof fabric detection process.

[0058] like Figure 5 As shown, a water pressure gauge 109 is provided on the servo water pump 102 , and the water pressure gauge 109 is used to monitor the water pressure value in the pressure water outlet 104 .

[0059] In this embodiment, a water pump support 110 is installed on the servo water pump 102 for fixing the servo water pump 102.

[0061] In this embodiment, gradient retaining rings 302 are provided at both ends of the cloth conveying roller 301, and the gradient retaining rings 302 are slidably connected to the cloth conveying roller 301. The position of the gradient retaining ring 302 is adjusted according to the size of the waterproof fabric to be detected, so that when the cloth conveying roller 301 conveys the waterproof fabric, the waterproof fabric is always at the center position of the cloth conveying roller 301, thereby avoiding deviation of the waterproof fabric during the conveying process.
