[0002] The water repellency test of fabrics mainly refers to the water repellency test standard GB / T 4745-2012. The test method is to install the fabric sample on the sample holder and place the sample holder at a 45-degree angle. Then, spray 250ml of water onto the fabric sample. After spraying, tap the sample holder. Then, compare the fabric sample with the standard pattern to determine the water repellency of the fabric sample and evaluate the waterproof performance of the fabric.

[0003] Currently, fabric water repellency testing is mainly conducted by workers using a fabric water repellency tester.

Detailed Implementation

[0021] 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.

[0022] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] See Figures 1-2This embodiment discloses an automatic water repellency testing and rating device, including a test chamber 1, and a sample loading mechanism 2, a spraying mechanism 3, a tapping mechanism 4, and a photographing and rating mechanism disposed within the test chamber 1. It also includes a control system 5 disposed outside the test chamber 1. The test chamber 1 serves as the load-bearing structure of the entire device, and all mechanisms are mounted through the test chamber 1. Simultaneously, the test chamber 1 provides a closed environment for the testing and rating operation, preventing external environmental factors such as wind speed, temperature, and humidity from affecting the test results. The control system 5 is used to interlock with each mechanism to control the automatic operation of the testing and rating process.

[0024] In this embodiment, the test chamber 1 is constructed as a rectangular box structure, which facilitates the installation of other mechanisms. The test chamber 1 is provided with an openable transparent door, such as a glass door, on at least one side, which facilitates the assembly of internal components and the observation of the internal working status of the test chamber.

[0025] like Figure 2 As shown, the spraying mechanism 3 and the shooting and rating mechanism are fixedly connected to the top of the test chamber 1 and distributed along the length of the test chamber 1. The sample loading mechanism 2 is connected to the bottom of the test chamber 1. In this embodiment, the sample loading mechanism 2 is movable, and by moving it, it can correspond to the position of the spraying mechanism 3 or the shooting and rating mechanism respectively, thereby switching between the spraying state and the rating state. The tapping mechanism 4 is also connected to the bottom of the test chamber 1 and is used to tap the sample loading mechanism 2 after spraying to remove water droplets from the surface. The tapping mechanism 4 can correspond to the position of the shooting and rating mechanism or can be set at the front end of the shooting and rating mechanism.

[0026] Specifically, the sample loading mechanism 2 includes a sample stage 21 for fixing the fabric sample and a sample holder for supporting the sample stage 21. The sample stage 21 adopts a circular sample loading clamp as used in the prior art. Figure 3 A schematic diagram of a circular sample loading clamp for clamping a fabric sample is shown. The fabric sample is placed on the inner ring 212 of the sample loading clamp, and then the outer ring 211 for clamping is fitted over the outer side of the inner ring 212 and the fabric sample. The sample stage 21 is rotatably connected to the sample holder, and by rotating, the sample stage 21 can switch between a horizontal state and a flipped state (e.g., at a 45° angle to the horizontal state).

[0027] In one embodiment, the sample holder includes two support frames 22, with bearing seats fixed at the top of each support frame 22. Rotating shafts 213 are fixed on both sides of the outer ring 211 of the sample stage 21, and are rotatably connected to the bearing seats via these shafts 213. To enable automatic rotation of the sample stage 21, the sample loading mechanism 2 further includes a drive motor (not shown) fixedly connected to the side of one of the support frames 22. The output shaft of the drive motor is fixedly connected to one of the rotating shafts of the sample stage 21, thereby driving the sample stage 21 to rotate. In this embodiment, the height of the support frames 22 is set between 12cm and 20cm, facilitating installation inside the test chamber 1 and also facilitating the rotation of the sample stage 21.

[0028] See Figure 2 To enable the sample loading mechanism 2 to move automatically, in this embodiment, the automatic detection and rating device further includes a transmission mechanism 8 for driving the sample loading mechanism 2 to move. The transmission mechanism 8 adopts an existing linear guide rail structure. The transmission mechanism 8 is fixedly connected to the bottom of the test chamber 1 along the length direction of the test chamber 1, and the two support frames 22 are fixedly connected to the output end of the linear guide rail.

[0029] In one embodiment, the sample loading mechanism 2 further includes a timer (not shown) and a pressure sensor 23 connected to the bottom of the support frame 22 for recording the spraying time. When the spraying mechanism 3 sprays the sample stage 21, the pressure sensor 23 senses the pressure and transmits the signal to the control system 5 connected thereto. The control system 5 controls the timer to start timing. When the spraying ends and the pressure sensor 23 no longer senses any pressure change, the timing ends.

[0030] See you again Figure 2The spraying mechanism 3 includes a funnel-shaped cavity 31 and a spray nozzle 32 connected to the bottom of the cavity 31. The cavity 31 is fixedly connected to the top of the test chamber 1 by a mounting bracket. In this embodiment, the top of the cavity 31 is a sealed structure. A water inlet pipe 33 is connected to the side of the cavity 31, and an air inlet pipe 34 is connected to the top. The water inlet pipe 33 and the air inlet pipe 34 extend out of the test chamber 1. The water inlet pipe 33 is connected to a water source outside the test chamber 1, and the air inlet pipe 34 is connected to a compressed air source outside the test chamber 1. The water inlet pipe 33 is connected to a metering pump 35 for on / off control and flow control. The metering pump 35 enables automatic water intake and precise control of the water intake. The air inlet pipe 34 is connected to an air pump 36 for on / off control and flow control. In this embodiment, by setting up a compressed air inlet pipe 34, the flow rate of the water can be controlled so that the water in the cavity 31 can be sprayed out within a preset time. On the other hand, the water pressure can be controlled. When the water in the cavity 31 is sprayed through the spray nozzle 32, the water pressure is controlled by compressed air, which can adjust the spray range of the spray nozzle 32 to ensure full coverage of the sample stage 21.

[0031] In one embodiment, the spraying mechanism 3 further includes a control valve 37 connected between the container 31 and the spray nozzle 32. During water intake, the control valve 37 is closed, allowing water to be stored in the container 31. When the water intake reaches a preset value, the metering pump 35 feeds back the signal to the connected control system 5. The control system 5 then activates the control valve 37 and the air pump 36, allowing compressed air to enter and spray water through the spray nozzle 32. Compared to the traditional method where workers pour water into the funnel while spraying, this method ensures a more consistent pouring speed, thereby ensuring the stability and accuracy of the test results.

[0032] See also Figure 2 The striking mechanism 4 includes two sets of striking parts, which can be connected to the bottom of the test chamber 1 or to both sides of the linear guide rail seat. The two sets of striking parts correspond to the bottom ends of the sample stage 21, respectively, and are used to strike the two ends of the sample stage 21 to remove water droplets from the fabric sample. Specifically, the striking part includes a telescopic rod 41 and a striking table 42 fixedly connected to the output end of the telescopic rod 41. In this embodiment, the telescopic rod 41 adopts an existing automatic telescopic rod structure, which can realize automatic linear telescopic movement with adjustable speed. For example, an electric push rod structure can be used. The striking table 42 is made of stainless steel to prevent corrosion. Driven by the telescopic rod 41, the striking table 42 can be raised and lowered, and touch and strike the bottom of the outer ring 211 of the sample stage 21. The striking force and the interval between the two ends of the striking are adjusted by the control system 5 through the motion control of the telescopic rod 41.

[0033] It should be noted that the sample stage 21 must be horizontal and the spray surface facing downwards during the tapping process. To prevent water from flowing horizontally during the tapping and spraying processes, in this embodiment, a first water-receiving groove (not shown in the figure) corresponding to the position of the fabric sample in the horizontal state is also connected between the two support frames 22. It should be noted that the first water-receiving groove should correspond as closely as possible to the position of the inner ring 212 in the width direction to prevent interference with the movement of the telescopic rod 41; and the first water-receiving groove should be located as close as possible to the bottom of the support frame 22 to prevent interference with the flipping of the sample stage 21. To further absorb excess moisture, preferably, a second water receiving tank 9 is provided at the bottom of the test chamber 1 and on both sides of the conveying mechanism 8. The second water receiving tank 9 extends from the position of the spraying mechanism 3 to the position of the striking mechanism 4. The second water receiving tank 9 is constructed as a cavity structure with a water leakage platform at the top. The water leakage platform has multiple holes so that the water that is screened out can flow into the cavity in time. Drainage pipes can be installed at the bottom of both the first water receiving tank and the second water receiving tank 9. The drainage pipes extend from the bottom of the test chamber 1.

[0034] like Figure 2 As shown, the shooting and grading mechanism includes a shooting unit 6 and a grading unit 7. The shooting unit 6 is fixedly connected to the top of the test chamber 1 and corresponds to the position of the striking mechanism 4. The shooting unit 6 is used to photograph and record the state of the fabric sample after the striking is completed, so as to facilitate traceability. The shooting unit 6 can use existing photo or video shooting equipment. When the sample stage 21 reaches the position of the shooting unit 6, the telescopic rod 41 drives the striking table 42 to rise at a constant speed and strike the sample stage 21. The telescopic rods 41 on both sides rise respectively, with an interval of about 3 seconds between them. After the impact is completed, the shooting unit 6 takes pictures of the front and back of the sample. In this embodiment, the clamping outer ring 211 of the sample stage 21 is adhered with a background layer. The background color can be adhered according to the color of the fabric sample to ensure a clearer shooting effect of the fabric sample, such as Figure 3 As shown, the corresponding outer ring 211 wall should have sufficient thickness to achieve better contrast shooting results.

[0035] The rating unit 7 is located at the rear end of the imaging unit 6 and includes a light emitting unit 71 and a signal receiving unit 72. The light emitting unit 71 is fixedly connected to the top of the test chamber 1, and the signal receiving unit 72 is configured in two sets, connected to the top of the test chamber 1 and the linear guide rail respectively. When the sample stage 21 moves to the area below the light emitting unit 71, the light emitting unit 71 emits fixed light rays onto the fabric sample. The reflected or transmitted light rays are received by the two signal receiving units 72. The signal receiving units 72 convert the light signals into electrical signals and transmit them to the control system 5 for rating result analysis. Preferably, the imaging and rating mechanism also includes a light amplifier 73 disposed between the light emitting unit 71 and the sample stage 21, which ensures that the light covers the entire sample.

[0036] It is understood that in this embodiment, each action of the automatic water-repellency detection and rating device is controlled by the control system 5. The control system 5 may specifically include a control chip or microcontroller that can control multiple mechanisms according to a predetermined program, so that each mechanism can start, stop or perform other actions according to a preset process.
