Description

Technical Field

[0001] This utility model relates to the field of weather resistance technology of textile fabrics, specifically a weather resistance testing device for textile fabrics. Background Technology

[0002] In the field of textile fabric production and application, weather resistance testing is an important step in assessing the ability of fabrics to resist the erosion of climatic factors such as light, temperature, humidity, wind and rain in actual use environments. Accurate weather resistance test data can not only guide the research and development and production of fabrics, but also directly affect the service life and quality of end products such as outdoor clothing, home decoration, and automotive interiors.

[0003] However, existing textile weather resistance testing devices generally suffer from cumbersome sample fixation methods and operating procedures. In some devices, the clamping structure is fixed inside the testing chamber. When clamping fabric samples, it is very laborious to operate inside the testing chamber, and the range of manual operation inside the testing chamber is limited. If the fabric is not firmly fixed, it is easy to slip or fall off during the testing process, affecting the accuracy and reliability of the test results. Moreover, when it is necessary to replace or repair the clamping device, the loading and unloading process often requires complicated disassembly and installation with the help of tools, which is not only time-consuming and labor-intensive, but also increases the workload of operators and reduces testing efficiency. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a weather resistance testing device for textile fabrics, which solves the problem of cumbersome sample fixing methods and operating procedures that are common in traditional weather resistance testing devices.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A weather resistance testing device for textile fabrics includes: a box structure, with a clamping device slidably connected to the inner wall of the box structure; the clamping device includes a connecting plate, a lifting threaded rod rotatably connected to the outer wall of the top of the connecting plate, a handle fixedly connected to the outer wall of the top of the lifting threaded rod, a lifting plate threadedly connected to the outer wall of the lifting threaded rod, guide rods symmetrically slidably connected to the inner wall of the lifting plate, L-shaped clamping plates fixedly connected to the outer wall of the bottom of the lifting plate and the outer wall of the top of the connecting plate, a clamping plate slidably connected to the inner wall of the bottom of the L-shaped clamping plate, a clamping threaded rod threadedly connected to the inner wall of the clamping plate, anti-slip pads fixedly connected to the outer walls of the L-shaped clamping plate and the clamping plate, and fixing grooves symmetrically formed on the outer wall of the side of the connecting plate.

[0009] Preferably, the outer wall at the bottom of the guide rod is fixedly connected to the outer wall at the top of the connecting plate. The L-shaped clamps are arranged in a ring around the central point of the connecting plate. Rotating the throttle causes the lifting threaded rod to rotate. Since the lifting threaded rod is threadedly connected to the lifting plate and the guide rod restricts the rotation of the lifting plate, it can only slide up and down.

[0010] Preferably, the outer wall of the clamping threaded rod is rotatably connected to the outer wall of the side of the L-shaped clamping plate, and a knob is fixedly connected to the outer wall of the clamping threaded rod. Rotating the clamping threaded rod causes the clamping plate to slide laterally on the inner wall at the bottom of the L-shaped clamping plate. An anti-slip pad covers the contact surface between the L-shaped clamping plate and the clamping plate, which can clamp the fabric sample by friction.

[0011] Preferably, the housing structure includes a weathering resistance testing machine. The outer wall of the weathering resistance testing machine has a testing chamber. A motor is fixedly connected to the inner wall of the bottom of the weathering resistance testing machine. A turntable is rotatably connected to the inner wall of the bottom of the testing chamber. A clamping groove is formed on the outer wall of the top of the turntable. A sliding rod is symmetrically fixedly connected to the inner wall of the clamping groove. A pull plate is slidably connected to the outer wall of the sliding rod. A compression spring is symmetrically fixedly connected to the outer wall of the pull plate. A clamping block is fixedly connected to the outer wall of the pull plate on the side away from the compression spring.

[0012] Preferably, the outer wall of the top of the motor shaft is fixedly connected to the outer wall of the bottom of the turntable. When the motor starts, the turntable can be rotated by the shaft. The inner wall of the clamping groove is slidably connected to the outer wall of the pull plate. The outer wall of the compression spring on the side away from the pull plate is fixedly connected to the inner wall of the clamping groove.

[0013] Preferably, the inner wall of the fixing groove is slidably connected to the outer wall of the clamping block, and the outer wall of the connecting plate is slidably connected to the inner wall of the turntable. When the connecting plate is inserted into the inner wall of the turntable, the fixing groove on the side of the connecting plate is aligned with the clamping groove on the turntable. In the initial state, the compression spring pushes the pull plate and the clamping block to expand outward. When the connecting plate is inserted into the turntable, the outer wall at the bottom of the connecting plate contacts the inclined surface on the clamping block, and the inclined surface squeezes the clamping block to slide outward along the clamping groove. At the same time, the compression spring is compressed and stores force. When the connecting plate is fully inserted into the turntable, the fixing groove corresponds to the clamping block. Through the elastic force of the compression spring returning to its original position, the pull plate is pushed to move inward along the slide rod, and the clamping block will be embedded in the fixing groove, fixing the clamping device on the turntable.

[0014] (III) Beneficial Effects

[0015] This invention provides a device for testing the weather resistance of textile fabrics. It has the following beneficial effects:

[0016] (i) The clamping device, through the cooperation of the lifting threaded rod and the guide rod, can flexibly adjust the distance between the upper and lower L-shaped clamping plates to adapt to fabric samples of different lengths. At the same time, rotating the clamping threaded rod can drive the clamping plate to slide laterally. Combined with the friction of the anti-slip pad, it can firmly clamp the fabric and prevent the sample from sliding or falling off during the testing process, ensuring the stable progress of the testing process.

[0017] (ii) The turntable uses a clamping block and a fixing groove locking structure driven by a compression spring between it and the connecting plate. When the connecting plate is inserted, the clamping block is contracted by the inclined surface. After the insertion is completed, the spring returns to its original position to achieve quick locking. When disassembling, it can be unlocked by manually pulling the pull plate. This greatly simplifies the sample installation and disassembly process, effectively improves the efficiency of the testing work, and reduces the labor intensity of the operators.

[0023] 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.

[0024] Please see Figure 1-4This utility model provides a technical solution: a weather resistance testing device for textile fabrics, comprising: a box structure 1, with a clamping device 2 slidably connected to the inner wall of the box structure 1; the clamping device 2 includes a connecting plate 21, a lifting threaded rod 22 rotatably connected to the outer wall of the top of the connecting plate 21, a handle 23 fixedly connected to the outer wall of the top of the lifting threaded rod 22, a lifting plate 24 threadedly connected to the outer wall of the lifting threaded rod 22, guide rods 25 symmetrically slidably connected to the inner wall of the lifting plate 24, L-shaped clamping plates 26 fixedly connected to the outer wall of the bottom of the lifting plate 24 and the outer wall of the top of the connecting plate 21, a clamping plate 27 slidably connected to the inner wall of the bottom of the L-shaped clamping plate 26, a clamping threaded rod 28 threadedly connected to the inner wall of the clamping plate 27, anti-slip pads 29 fixedly connected to the outer walls of the L-shaped clamping plate 26 and the clamping plate 27, and fixing grooves 291 symmetrically opened on the outer wall of the side of the connecting plate 21.

[0025] The outer wall at the bottom of the guide rod 25 is fixedly connected to the outer wall at the top of the connecting plate 21. The L-shaped clamps 26 are arranged in a ring along the central point of the connecting plate 21. Rotating the handle 23 drives the lifting threaded rod 22 to rotate. Since the lifting threaded rod 22 is threadedly connected to the lifting plate 24 and the guide rod 25 restricts the rotation of the lifting plate 24, it can only slide up and down.

[0026] The outer wall of the clamping threaded rod 28 is rotatably connected to the outer wall of the side of the L-shaped clamping plate 26. A knob is fixedly connected to the outer wall of the clamping threaded rod 28. Rotating the clamping threaded rod 28 causes the clamping plate 27 to slide laterally on the inner wall of the bottom of the L-shaped clamping plate 26. The anti-slip pad 29 covers the contact surface between the L-shaped clamping plate 26 and the clamping plate 27, and can clamp the fabric sample by friction.

[0027] The housing structure 1 includes a weathering resistance testing machine 11. The outer wall of the weathering resistance testing machine 11 has a testing chamber 12. The inner wall of the bottom of the weathering resistance testing machine 11 is fixedly connected to a motor 13. The inner wall of the bottom of the testing chamber 12 is rotatably connected to a turntable 14. The outer wall of the top of the turntable 14 has a clamping groove 15. The inner wall of the clamping groove 15 is symmetrically fixedly connected to a slide rod 16. The outer wall of the slide rod 16 is slidably connected to a pull plate 17. The outer wall of the pull plate 17 is symmetrically fixedly connected to a compression spring 18. The outer wall of the pull plate 17 away from the compression spring 18 is fixedly connected to a clamping block 19.

[0028] The outer wall of the top of the rotating shaft of the motor 13 is fixedly connected to the outer wall of the bottom of the turntable 14. When the motor 13 is started, it can drive the turntable 14 to rotate through the rotating shaft. The inner wall of the clamping groove 15 is slidably connected to the outer wall of the pull plate 17. The outer wall of the compression spring 18 on the side away from the pull plate 17 is fixedly connected to the inner wall of the clamping groove 15.

[0029] The inner wall of the fixing groove 291 is slidably connected to the outer wall of the clamping block 19, and the outer wall of the connecting plate 21 is slidably connected to the inner wall of the turntable 14. When the connecting plate 21 is inserted into the inner wall of the turntable 14, the fixing groove 291 on the side of the connecting plate 21 is aligned with the clamping groove 15 on the turntable 14. In the initial state, the compression spring 18 pushes the pull plate 17 and the clamping block 19 to expand outward. When the connecting plate 21 is inserted into the turntable 14, the outer wall at the bottom of the connecting plate 21 contacts the inclined surface on the clamping block 19, and the inclined surface squeezes the clamping block 19 to slide outward along the clamping groove 15. At the same time, the compression spring 18 is compressed and stored. When the connecting plate 21 is fully inserted into the turntable 14, the fixing groove 291 corresponds to the clamping block 19. Through the elastic force of the compression spring 18 returning to its original position, the pull plate 17 is pushed to move inward along the slide rod 16. At the same time, the clamping block 19 will be embedded in the fixing groove 291, fixing the clamping device 2 on the turntable 14.

[0030] In use, the device simulates the climate environment through the weather resistance tester 11 in the box structure 1, fixes the textile fabric sample with the clamping device 2, and drives the sample to rotate in the test chamber 12 through the turntable 14 to achieve multi-directional and uniform weather resistance testing.

[0031] First, turn the handle 23 to drive the lifting threaded rod 22 to rotate. Since the lifting threaded rod 22 is threadedly connected to the lifting plate 24 and the guide rod 25 restricts the rotation of the lifting plate 24, so that it can only slide up and down, the lifting plate 24 will move up and down along the guide rod 25 to adjust the distance between the L-shaped clamp 26 on the connecting plate 21 and the L-shaped clamp 26 on the lifting plate 24 to accommodate fabric samples of different lengths.

[0032] When the appropriate length is adjusted, place the fabric sample between the L-shaped clamp 26 and the clamping plate 27, rotate the clamping threaded rod 28, and drive the clamping plate 27 to slide laterally on the inner wall of the bottom of the L-shaped clamp 26. The anti-slip pad 29 covers the contact surface of the L-shaped clamp 26 and the clamping plate 27, and can clamp the fabric sample by friction to prevent the sample from sliding or falling off during the test.

[0033] After the fabric sample is fixed in the clamping device 2, the connecting plate 21 is then inserted into the inner wall of the turntable 14. At this time, the fixing groove 291 on the side of the connecting plate 21 is aligned with the clamping groove 15 on the turntable 14. In the initial state, the compression spring 18 pushes the pull plate 17 and the clamping block 19 to expand outward. When the connecting plate 21 is inserted into the turntable 14, the outer wall of the bottom of the connecting plate 21 contacts the inclined surface on the clamping block 19, and the inclined surface squeezes the clamping block 19 to slide outward along the clamping groove 15. At the same time, the compression spring... When the connecting plate 21 is fully inserted into the turntable 14, the fixing groove 291 corresponds to the clamping block 19. The spring force of the compression spring 18 pushes the pull plate 17 to move inward along the slide rod 16. At the same time, the clamping block 19 will be embedded in the fixing groove 291, fixing the clamping device 2 on the turntable 14 to ensure that it will not fall off during rotation. Conversely, if the pull plate 17 is pulled outward manually, the compression spring 18 will be compressed, the clamping block 19 will exit the fixing groove 291, and the connecting plate 21 can be removed.

[0034] After the clamping device 2 is installed, the motor 13 starts and drives the turntable 14 to rotate through the rotating shaft. This causes the clamping device 2 and the fixed fabric sample to make circular motion in the detection chamber 12. During the rotation, the sample can be evenly exposed to the climate environment simulated by the detection machine, avoiding the problem of insufficient local detection.
