Description

Technical Field

[0001] This utility model relates to the field of textiles, specifically to a device for testing the water resistance of textiles. Background Technology

[0002] In the textile industry, the water resistance of textiles is one of the key indicators for evaluating their quality and suitability. It is widely used in outdoor clothing, home textiles, medical protective materials and other fields. As the market continues to increase its requirements for the functionality of textiles, higher demands are being placed on the accuracy, efficiency and ability to simulate real-world usage scenarios of water resistance testing devices.

[0003] Traditional testing devices for the water resistance of textiles rely on relatively simple methods, often employing static spraying or single-angle spraying. These methods fail to realistically simulate the stress and water exposure experienced by textiles during actual use (such as deformation caused by human movement during wear, and different rainfall angles). This results in significant discrepancies between the test results and actual application scenarios, failing to accurately reflect the water resistance of textiles in complex environments. In water resistance testing of outdoor clothing, static testing cannot simulate the impact of fabric structure changes caused by stretching and twisting during movement on waterproof performance. Therefore, we propose a new water resistance testing device for textiles. Utility Model Content

[0042] Water tank 3: One side is hollow and has a circular hole. The four sides are fixed to the inner wall of the test box 1. It is set up with a surrounding support structure. It is mainly used to store test water and provide water source for the sprayer 4.

[0043] Sprayer 4: Installed on the cylindrical surface inside water tank 3, it is in the shape of a circular nozzle with evenly distributed circumference. It sprays water onto the textiles and simulates various rainfall scenarios by activating it from different directions to test the water resistance of the textiles.

[0044] Rotating plate 5: It is a round or square flat plate with a rotating shaft 14 connected to the center of one side and a supporting structure installed on the other side. Driven by motor 13, it drives the textile to rotate, realizing multi-angle water resistance testing.

[0045] The expansion plate 6 is rectangular in shape, with a fixing groove 8 through its opposite sides. One side is fixed to the rotating plate 5, while the other side is movable and adjustable. It is used to place and fix textiles. By adjusting the spacing, it can adapt to different sizes and also adjust the tension of the textiles. The lead screw 7 is a cylindrical long rod. One end is rotatably connected to the expansion plate 6, and the other end passes through the bearing seat 15 and is fitted with a handle. By rotating the handle, the movable expansion plate 6 is moved to achieve the adjustment of spacing and tension.

[0046] Fixed groove 8: It is a long strip groove that runs through the support plate 6. A positioning block 9 is provided on the side opposite to the top surface of the test box 1 for inserting and placing textiles, and the positioning block 9 is used to fix the position of the textiles.

[0047] Positioning block 9: consists of multiple columnar protrusions evenly distributed along a straight line within the fixing groove 8, which hold the perforated textile and prevent it from shifting during the inspection process;

[0048] Strip groove 10: It is a long strip groove opened on the side of the rotating plate 5 away from the rotating shaft 14, corresponding to the lead screw 7, restricting the movement direction of the supporting structure and preventing the movable supporting plate 6 from rotating with the lead screw 7;

[0049] Limiting block 11: A block-shaped structure fixed to one side of the movable support plate 6, which slides and engages with the strip groove 10 to further ensure that the movable support plate 6 moves linearly along the strip groove 10 and stably adjusts the tension of the textile.

[0050] Mounting frame 12: This is a frame structure that is fixed to the back of the detection box 1, providing a mounting base for the angle adjustment structure and ensuring the stable operation of components such as motor 13 and rotating shaft 14;

[0051] Motor 13: The main body is cylindrical or square, and it drives the rotating shaft 14 and the rotating plate 5 to rotate through the output shaft, so as to realize the multi-angle adjustment of the textile.

[0052] Rotary shaft 14: It is a cylindrical shaft with one end connected to the output shaft of motor 13 and the other end fixed to the rotating plate 5. It serves as a transmission component to transmit the power of motor 13 to the rotating plate 5.

[0053] Bearing housing 15: It is a block structure with a bearing inside, used to install the lead screw 7, support the rotation of the lead screw 7, and ensure its stable operation;

[0054] Threaded hole 16: This is an internal threaded hole that passes through the movable support plate 6 and is threadedly connected to the lead screw 7, so that the rotation of the lead screw 7 is converted into the linear movement of the movable support plate 6, thereby realizing the spacing adjustment.

[0055] Working principle: Open the door panel assembly of the testing box 1, drill holes in the edge of the textile to be tested and insert it into the fixing grooves 8 on the opposite sides of the two support plates 6. The positioning blocks 9 evenly distributed in the fixing grooves 8 hold the textile in place, achieving initial fixation. Then, rotate the handle at the end of the lead screw 7. Since the lead screw 7 is threadedly connected to the threaded hole 16 on the movable support plate 6, during the rotation, the lead screw 7 rotates and drives the movable support plate 6 to move linearly along the strip groove 10. At the same time, the limiting block 11 slides and engages with the strip groove 10, restricting the rotation of the movable support plate 6, so that it can only move along the direction of the strip groove 10, thereby adjusting the distance between the two support plates 6. This not only adapts to textiles of different sizes, but also applies appropriate tension to the textiles according to the testing requirements, simulating the stretching state when clothing is worn. The mounting frame 12 is fixed to the back of the testing box 1, providing a mounting base for the internal structure. The motor 13 in the angle adjustment structure is fixed to the inner wall of the mounting frame 12. When the motor 13 starts, its output shaft drives the rotating shaft 14 to rotate through the coupling. The rotating shaft 14 is then connected to the... The rotating plate 5 is fixedly connected, thereby driving the rotating plate 5 to rotate inside the testing box 1. The rotation angle and speed of the motor 13 are set by the PLC control system, which allows the rotating plate 5 to drive the supporting structure and textile to rotate arbitrarily within the range of 0-360°, realizing the adjustment of different angles of the textile and simulating its state under different rainfall directions or human movement postures in actual use. The water tank 3 of the all-round spray structure is fixed on the four inner walls of the testing box 1 and is set around the supporting structure to store the water required for testing. Multiple sprayers 4 are evenly distributed on the circumference of the cylindrical surface inside the water tank 3. When the textile is adjusted to a suitable angle, the system starts the sprayers 4 in the corresponding position according to the preset program. For example, the top sprayer 4 is started when simulating vertical rainfall, and the side sprayers 4 are started when simulating oblique rain. The water pressure and spray angle of the sprayers 4 can be adjusted by the control system to conduct multi-angle and multi-intensity water spray tests on the textile. During the spraying process, the angle adjustment structure controls the rotation of the textile so that different parts can be sprayed to comprehensively test its water resistance performance.
