Description

Technical Field

[0001] This utility model relates to the field of fabric testing technology, specifically to a multi-directional stretch dynamic moisture permeability testing device for moisture-absorbing composite fabrics. Background Technology

[0002] Moisture-wicking composite fabrics are multifunctional textiles made by laminating or bonding fiber layers with moisture-wicking properties to other materials.

[0003] Currently, moisture-wicking composite fabrics are increasingly widely used in sportswear, medical protective equipment, and outdoor gear, leading to a growing demand for performance testing. Traditional equipment often employs uniaxial stretching or fixed clamping methods, resulting in limited expansion structures and an inability to adapt to fabric samples of different sizes and elasticities. This leads to low testing efficiency, particularly in the case of irregularly shaped fabrics, where insufficient compatibility results in moisture permeability test data that deviate significantly from actual usage performance. Therefore, improving existing testing equipment and designing a novel multi-directional stretching dynamic moisture permeability testing device for moisture-wicking composite fabrics to address these technical shortcomings and enhance the overall practicality of the testing equipment is of paramount importance. Utility Model Content

[0004] The purpose of this invention is to provide a multi-directional tensile dynamic moisture permeability testing device for moisture-wicking composite fabrics. This device solves the problem that traditional devices mostly use uniaxial tensile or fixed clamping methods, have a single expansion structure, and cannot adapt to fabric samples of different sizes and elasticities, resulting in low testing efficiency. In particular, the device lacks compatibility with irregularly cut fabrics, leading to a large deviation between the moisture permeability test data and the actual usage effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-directional tensile dynamic moisture permeability testing device for moisture-absorbing composite fabrics includes an evaporation chamber body, a connecting frame fixedly connected inside the evaporation chamber body, an extension component on the top of the connecting frame, and connecting components on all four sides inside the extension component.

[0007] The expansion component is used to adjust the position of multiple sets of connecting components. The expansion component includes two sets of first movable frames that are slidably connected to the top ends of the connecting frame. Two sets of rotating rods are rotatably connected to one end of each set of first movable frames that are close to each other. The two sets of rotating rods are connected through a second movable frame.

[0008] The connecting component is used to clamp the fabric.

[0009] As a preferred embodiment of this utility model, the connecting frame is rotatably connected to a positive and negative lead screw, and the positive and negative lead screw extends to the outside of the connecting frame and is fixedly connected to the drive end of a drive motor.

[0010] As a preferred embodiment of this utility model, the drive motor and the connecting frame are fixedly connected, and the first movable frame moves axially on the outside of the positive and negative lead screws via ball bearings.

[0011] As a preferred embodiment of this utility model, sliding grooves are provided on both sides inside the first movable frame, and the second movable frame is slidably connected to the sliding grooves. The second movable frame is connected to the first movable frame through the sliding grooves.

[0012] As a preferred embodiment of this utility model, the multiple sets of connecting components include a connecting frame fixedly connected to the middle of the interior of two sets of first movable frames and second movable frames. A movable block is provided on the outer side of the connecting frame. Two sets of connecting rods are rotatably connected to the outer side of the movable block. A clamping block is fixedly connected to the end of the connecting rod away from the connecting frame, and a guide rod is rotatably connected to the end of the connecting rod away from the clamping block.

[0013] As a preferred embodiment of this utility model, the end of the guide rod away from the connecting rod is rotatably connected to the connecting frame. The connecting rod has an "L" shaped structure design. Multiple sets of friction blocks are fixedly connected to the inner side of the clamping block. An electric telescopic rod is fixedly connected inside the connecting frame. The driving end of the electric telescopic rod is fixedly connected to the moving block.

[0014] As a preferred embodiment of this utility model, an evaporator is fixedly connected inside the main body of the evaporator and below the connecting frame, and a transparent closing plate is rotatably connected to the top of the main body of the evaporator.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, through the design of the extension component, the extension component consists of two sets of first moving frames, rotating rods, and a second moving frame forming a linkage mechanism. Multi-directional displacement is achieved by driving the positive and negative lead screws. The drive motor drives the positive and negative lead screws to rotate, causing the two sets of first moving frames to move in opposite directions along the axial direction. When the first moving frame is displaced, the rotating rod pushes the second moving frame to move synchronously, forming a four-way extension structure. The sliding groove and ball structure ensure the stable sliding of the second moving frame, adapting to the stretching requirements of fabrics of different sizes. It can simulate the multi-directional stress state of the fabric in actual use, improving the realism of the test. The synchronous displacement of the four sets of connecting components avoids single-point stress concentration and ensures the reliability of the test data.

[0017] 2. In this utility model, through the design of the connecting component, the clamping component is driven by the electric telescopic rod to move the block. The L-shaped connecting rod is linked with the guide rod to control the opening and closing of the clamping block. The electric telescopic rod can quickly clamp or release, improving testing efficiency. When the extension component stretches the fabric, the connecting component maintains stable clamping. The synchronous evaporator simulates the human body temperature and humidity environment, accurately evaluating the fabric's moisture permeability. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] A multi-directional tensile dynamic moisture permeability testing device for moisture-absorbing composite fabrics includes an evaporation chamber body 1, a connecting frame 2 fixedly connected inside the evaporation chamber body 1, an extension component 3 on the top of the connecting frame 2, and connecting components 4 on all four sides inside the extension component 3.

[0027] The extension component 3 is used to adjust the position of multiple sets of connecting components 4. The extension component 3 includes two sets of first movable frames 5 that are slidably connected to the top ends of the connecting frame 2. Two sets of rotating rods 6 are rotatably connected to the ends of the two sets of first movable frames 5 that are close to each other. The two sets of rotating rods 6 are connected through a second movable frame 7.

[0028] The connecting component 4 is used to clamp the fabric.

[0029] Furthermore, the connecting frame 2 is rotatably connected to a positive and negative lead screw 8. The positive and negative lead screw 8 extends to the outside of the connecting frame 2 and is fixedly connected to the drive end of the drive motor 9. The drive motor 9 is fixedly connected to the connecting frame 2. The first moving frame 5 moves axially on the outside of the positive and negative lead screw 8 through the ball bearings. The drive motor 9 is started, which drives the positive and negative lead screw 8 to rotate, so that the two sets of first moving frames 5 can move closer to each other. At the same time, the displacement of the first moving frame 5 drives the rotating rod 6 to move. Through the two sets of rotating rods 6, the second moving frame 7 can move, bringing the two sets of second moving frames 7 closer to each other, so that multiple sets of connecting components 4 can move closer to each other.

[0030] The first movable frame 5 has sliding grooves 10 on both sides inside. The second movable frame 7 is slidably connected to the sliding grooves 10. The second movable frame 7 is connected to the first movable frame 5 through the sliding grooves 10. When the second movable frame 7 moves, it can be guided by the sliding grooves 10, so that the second movable frame 7 can move stably.

[0031] Secondly, the multiple connecting components 4 include a connecting frame 11 fixedly connected to the middle of the two sets of first movable frames 5 and second movable frames 7. A movable block 12 is provided on the outside of the connecting frame 11. Two sets of connecting rods 13 are rotatably connected to the outside of the movable block 12. A clamping block 14 is fixedly connected to the end of the connecting rod 13 away from the connecting frame 11. A guide rod 15 is rotatably connected to the end of the connecting rod 13 away from the clamping block 14. The end of the guide rod 15 away from the connecting rod 13 is rotatably connected to the connecting frame 11. The connecting rod 13 has an "L" shaped structure design. Multiple sets of friction blocks 16 are fixedly connected to the inner side of the clamping block 14. An electric telescopic rod 17 is fixedly connected to the inside of the connecting frame 11. The drive end of the electric telescopic rod 17 is fixedly connected to the moving block 12. When the fabric is placed between the two sets of clamping blocks 14, the electric telescopic rod 17 is activated to drive the moving block 12 closer to the connecting frame 11, so that the connecting rod 13 can be displaced. With the help of the guide rod 15, the connecting rod 13 can be guided, and the two sets of clamping blocks 14 are brought closer to each other to clamp the fabric, thereby fixing the fabric.

[0032] Furthermore, an evaporator is fixedly connected inside the evaporator body 1 and below the connecting frame 2. A transparent closing plate 18 is rotatably connected to the top of the evaporator body 1. When the fabric is fixed inside the evaporator body 1, the evaporator fixedly connected inside the evaporator body 1 will continuously generate humid steam. The environmental parameters are monitored in real time by the built-in sensor of the evaporator. The humidity sensor calibrates the humidity, and the temperature sensor calibrates the temperature. When the temperature reaches 37°C and the humidity reaches 90%, the system automatically enters the steady-state maintenance mode.

[0033] It is worth noting that the evaporator, sensor, drive motor 9, and electric telescopic rod 17 mentioned in this application are externally connected to control switches and drive power supplies. Furthermore, the evaporator, sensor, drive motor 9, and electric telescopic rod 17 are all conventional and known devices. The standard parts used in this application can all be purchased from the market. The specific connection methods of each part are all connected using conventional methods such as bolts, rivets, and welding that are mature in the prior art. Moreover, the machinery, parts, and equipment all use conventional models in the prior art. In addition, the circuit connection uses conventional connection methods in the prior art. The contents not described in detail in the description belong to the prior art known to those skilled in the art, and will not be described in detail here.

[0034] In this embodiment, the specific implementation scenario is as follows: In actual use, the drive motor 9 is started, driving the positive and negative lead screws 8 to rotate, so that the two sets of first moving frames 5 can move closer to each other. At the same time, the displacement of the first moving frames 5 drives the rotating rod 6 to move, and the two sets of rotating rods 6 cause the second moving frames 7 to move closer to each other, so that multiple sets of connecting components 4 can move closer to each other. The fabric is placed between the two sets of clamping blocks 14. The electric telescopic rod 17 is started, driving the moving block 12 to move closer to the connecting frame 11, so that the connecting rod 13 can move. With the help of the guide rod 15, the connecting rod 13 can be guided, and the two sets of clamping blocks 14 can move closer to each other to clamp the fabric, thereby fixing the fabric. The two sets of first moving frames 5 and second moving frames 7 are reset, so that the fabric clamped by multiple sets of connecting components 4 can be unfolded. Moist steam is introduced into the interior of the evaporator body 1, and the temperature is maintained at 37°C and the humidity is maintained at 90%, so that the fabric can be tested. Compared with existing testing equipment, this utility model can improve the overall practicality of the testing equipment through design.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
