Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of performance detection of moisture absorption fabric, and particularly relates to a performance detection device and a detection method for moisture absorption fabric. BACKGROUND

[0002] In the performance detection of moisture absorption fabric, the traditional process often adopts a method of vertically putting the fabric into water, which prevents the existence of air bubbles on the surface of the fabric, thereby affecting the water absorption speed, and facilitates draining.

[0003] However, when the fabric is vertically put into water, the liquid on both sides of the fabric rises at a consistent speed under the action of capillary force, which is faster than the escape speed of the gas inside the fabric, which means that when the water rapidly climbs along both sides of the fabric, the air inside the fabric does not have enough time to escape, and as the water continuously rises, the liquid on both sides meets at the top to form a closed water film, which traps the air that has not escaped inside the fabric to form air bubbles. The existence of these air bubbles interferes with the normal penetration and diffusion of water, resulting in uneven water absorption inside the fabric, and ultimately affecting the accuracy of the detection result. SUMMARY

[0012] The performance detection device of the moisture absorption fabric as described above: the limiting piece is provided on the side of the sliding sleeve, and an inclined surface and a limiting groove are provided on the limiting piece, when the sliding sleeve moves upward to the stroke end, the second convex shaft can be guided into the limiting groove by the inclined surface, so that the pressing plate is separated from the horizontal shaft.

[0013] The performance testing device for moisture-wicking fabric as described above: the elastic tension structure includes a horizontal sleeve disposed on the sliding sleeve, a connecting frame slidably mounted on the horizontal sleeve, the connecting frame being rotatably connected to the pressure roller, and the connecting frame being connected to the sliding sleeve via a third cylindrical spring; the side of the connecting frame being rotatably connected to the second abutment shaft; two sets of guide surfaces are symmetrically arranged on the trigger element, and the second abutment shaft cooperates with the guide surfaces to enable the two sets of connecting frames to move away from each other.

[0014] A method for testing the performance of a moisture-wicking fabric using the aforementioned performance testing device includes the following steps: Step 1: The deflection frame is brought into a vertical position by the drive structure, and then the fabric to be tested is passed through the first clamping assembly and the tensioning assembly; Step 2: Push the tensioning component downwards so that the first clamping component can clamp one end of the fabric, and the tensioning component can tension the fabric as it moves along the length of the deflection frame. Step 3: When the tensioning component is about to move to the lower end of its stroke, place the other end of the fabric into the second clamping component. Then, drive the deflection frame to deflect through the drive structure, so that the second clamping component clamps the other end of the fabric and deflects the deflection frame at a predetermined angle. Finally, let the tensioning component continue to move until the tensioning component separates from the fabric. At this time, the testing machine weighs the fabric. Step 4: Control the horizontal plate to move towards the inside of the testing machine body, so that the liquid in the testing machine body gradually submerges the horizontal plate; Step 5: Raise the horizontal plate to the initial position, and then use the drive structure to make the deflection frame vertical. At this time, the second clamping component separates. In this state, the fabric is in a natural hanging state. In this state, allow the fabric to drip for a certain period of time, and then weigh the fabric to determine the moisture absorption of the fabric.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The first clamping component, the second clamping component, the deflection frame, and the driving structure enable the deflection frame to have two switchable states: vertical and inclined. This facilitates the clamping of the fabric to be tested onto the deflection frame. Furthermore, after the fabric is soaked, by keeping it vertical following the deflection frame, the water on the fabric can be drained more easily, thus eliminating free water adhering to the fabric surface due to liquid tension and improving detection accuracy. On the other hand, the fabric can be tilted into the water, resulting in uneven water absorption on both sides. This allows the lateral movement of the liquid within the fabric to push out internal gas from the sides, preventing gas from being trapped by the liquid under capillary force, thus further improving detection accuracy. The first clamping component and the tensioning component ensure that the fabric is taut during loading and allows it to hang naturally when draining free water, preventing the fabric from bending and wrinkling in the lower section due to gravity after absorbing water, allowing the free water on the fabric to drain quickly.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Please see Figures 1-9 As an embodiment of the present invention, the performance testing device for the moisture-wicking fabric includes: a testing machine body 1, a deflection frame 4, a drive structure, and a tensioning component.

[0020] The testing machine body 1 is equipped with a horizontal plate 3 that can be raised and lowered. Specifically, the testing machine body 1 contains liquid for the fabric to absorb, and a lifting drive 2 for driving the horizontal plate 3 to rise and fall is also provided inside the testing machine body 1. The drive structure is set on the horizontal plate 3, and the drive structure can drive the deflection frame 4 to deflect by a predetermined angle. The drive structure includes an electric telescopic rod 27 fixedly installed on the horizontal plate 3 and a drive frame 26 that slides along the length direction of the horizontal plate 3. The drive frame 26 is provided with a vertical groove 2601. The drive structure also includes an extension plate 25 fixedly connected to the rotating shaft of the deflection frame 4. The end of the extension plate 25 away from the rotating shaft of the deflection frame 4 is provided with a fitting shaft 2501, and the fitting shaft 2501 can slide in the vertical groove 2601.

[0021] In this embodiment, when the electric telescopic rod 27 pushes the drive frame 26 to slide along the length of the transverse plate 3, the vertical groove 2601 can cooperate with the fitting shaft 2501, causing the deflection frame 4 to rotate, thereby making the position of the deflection frame 4 adjustable. Specifically, the deflection frame 4 has two position states: one is that the deflection frame 4 is in a vertical state, which makes it easier to clamp the fabric to be tested onto the deflection frame 4. At the same time, after the fabric is soaked, by making the fabric follow the vertical position of the deflection frame 4, the water on the fabric can be drained more easily, thereby eliminating the free water attached to the fabric surface due to liquid tension and improving the detection accuracy; the other is that the deflection frame 4 is in an inclined state. At this time, when the transverse plate 3 moves towards the liquid, the fabric can be tilted into the water, so that the water absorption speed on both sides of the fabric is different. This allows the lateral movement of the liquid in the fabric to push the gas inside the fabric out from the side of the fabric, avoiding the gas inside the fabric being wrapped by the liquid under the action of capillary force, resulting in residual air bubbles inside the fabric, which further improves the detection accuracy to a certain extent.

[0022] Please see Figures 5-6 The deflection frame 4 is provided in multiple sets and installed on the horizontal plate 3. One end of the deflection frame 4 is provided with a first clamping assembly, and the other end is provided with a second clamping assembly. The second clamping assembly is provided with a first abutting shaft 8. The first abutting shaft 8 is adapted to the ejector installed on the horizontal plate 3. The ejector includes a bracket 5 fixedly installed on the horizontal plate 3. The bottom of the bracket 5 is provided with a protrusion 501. The protrusion 501 cooperates with the first abutting shaft 8 and can drive the lifting plate 7 to slide along the length direction of the second sliding connection part 402. The first clamping assembly includes: two sets of sliding members 6, a first cylindrical spring 9, and a trigger pressing structure. The two sets of sliding members 6 are slidably installed in the first sliding connection part 401 opened on the side of the deflection frame 4, and a clamp is formed on the sliding member 6. The device includes a holding part 602; two sets of the first cylindrical spring 9 are provided, one end of which is connected to the deflection frame 4 and the other end is connected to the sliding member 6; the trigger pressing structure is slidably mounted on the deflection frame 4, and the trigger pressing structure can drive the two sets of sliding members 6 to move away from each other when the first abutting shaft 8 is engaged with the ejector; the trigger pressing structure includes a second sliding connection part 402 provided on the deflection frame 4 and a lifting plate 7 slidably mounted on the second sliding connection part 402, and two sets of inclined grooves 701 are symmetrically provided on the lifting plate 7; the trigger pressing structure also includes a first convex shaft 601 rotatably connected to the sliding member 6, and the first convex shaft 601 is slidably connected to the inclined groove 701; the first abutting shaft 8 is rotatably connected to the lifting plate 7.

[0023] In the initial state, the first cylindrical spring 9 is in a stretched state, and the two sets of sliding parts 6 are in abutting each other, so that the two sets of clamping parts 602 can clamp the lower end of the fabric. At the same time, in this state, the second clamping assembly clamps the upper end of the fabric, so that when the deflector 4 is in an inclined state, the fabric can also be in an inclined state, so that the fabric can enter the water in a stable inclined state, and the air inside the fabric can be discharged by taking advantage of the different adsorption speeds of the liquid on both sides of the fabric.

[0024] When the deflector 4 switches to the vertical position, the first abutment shaft 8 will cooperate with the protrusion 501. At this time, driven by the protrusion 501, the first abutment shaft 8 will drive the lifting plate 7 to move along the length direction of the second sliding connection part 402. At the same time, the first convex shaft 601 cooperates with the inclined groove 701, which can make the two sets of sliding parts 6 move away from each other. That is, in this state, the two sets of clamping parts 602 are in a state of being far apart from each other. In this state, firstly, it is easier to put the fabric to be tested between the two sets of clamping parts 602. Secondly, when the fabric has finished absorbing water and the deflector 4 is deflected to the vertical position, by separating the two sets of clamping parts 602, the bottom of the fabric can be released, so that the fabric can be in a natural hanging state, avoiding the situation where the middle and lower sections of the fabric bend and wrinkle due to gravity after absorbing water, so that the free water on the fabric can be drained quickly.

[0025] Furthermore, in the initial state, when the upper end of the fabric is fixed and the lower end passes through the two sets of clamping parts 602, the deflection frame 4 can be deflected to change the water entry angle of the fabric and to separate the first abutting shaft 8 from the protrusion 501, thereby achieving automatic clamping of the fabric using the two sets of clamping parts 602.

[0026] Please see Figures 7-9 The second clamping assembly includes a horizontal shaft 15 fixedly connected to the deflection frame 4 and coaxial with the rotation axis of the deflection frame 4, and a follower plate 11 fixedly installed on the horizontal shaft 15. The follower plate 11 is provided with a slide groove 1101 along its length direction. A slider 12 is slidably installed in the slide groove 1101. A pressure plate 14 that cooperates with the horizontal shaft 15 to clamp the fabric is connected to the slider 12. The slider 12 is connected to the inner wall of the slide groove 1101 through a second columnar spring 13, and a second convex shaft 16 is rotatably installed on the slider 12. The second convex shaft 16 is adapted to a limiting member 17 provided on the side of the tensioning assembly. The limiting member 17 is provided with an inclined surface 1701 and a limiting groove 1702. When the sliding sleeve 10 moves upward to the end of its stroke, the second convex shaft 16 can be guided by the inclined surface 1701 into the limiting groove 1702, so that the pressure plate 14 is separated from the horizontal shaft 15.

[0027] In the initial state, the second cylindrical spring 13 is stretched, so that under the pulling force provided by the second cylindrical spring 13, the pressure plate 14 has a pressing force on the horizontal shaft 15. Under the action of this force, the pressure plate 14 and the horizontal shaft 15 can clamp and fix the upper end of the fabric. When the tensioning assembly moves towards the highest point of its stroke, the limiting member 17 will also move upward. At this time, the inclined surface 1701 on the limiting member 17 will abut against the second convex shaft 16, so that the second convex shaft 16 can drive the slider 12 to move in a direction away from the second cylindrical spring 13, thereby separating the pressure plate 14 and the horizontal shaft 15. At this point, it is easier to pass the fabric through the pressure plate 14 and the horizontal shaft 15. When the tensioning component moves to the end of its stroke, the second convex shaft 16 will move into the limiting groove 1702. At this time, the pressure plate 14 will still remain separated from the horizontal shaft 15. At the same time, the limiting groove 1702 and the second convex shaft 16 cooperate to limit the tensioning component, so that the tensioning component can maintain a predetermined position relative to the deflection frame 4 without changing. This prevents the tensioning component from moving along the length of the deflection frame 4 under its own weight, causing the pressure plate 14 and the horizontal shaft 15 to automatically abut, which would be inconvenient when clamping the upper end of the fabric.

[0028] Please refer to it again. Figures 7-9 The tensioning assembly is mounted on the deflection frame 4 and can slide along the length of the deflection frame 4. Two sets of pressure rollers 22 are provided at each end of the tensioning assembly, and the tensioning assembly cooperates with two sets of trigger elements 24 mounted on the deflection frame 4, enabling the two sets of pressure rollers 22 to move away from each other when the tensioning assembly moves to the end of its stroke. The tensioning assembly includes: a sliding sleeve 10 slidably mounted on the deflection frame 4, a push-pull frame 18 connected to the sliding sleeve 10, and a limiting element 17 provided on the sliding sleeve 10; an elastic tensioning structure provided on the sliding sleeve 10, the elastic tensioning structure connected to the pressure rollers 22, and the elastic tensioning structure is provided with... A second abutment shaft 23 adapted to the trigger 24 is provided; the elastic tension structure includes a horizontal sleeve 19 disposed on the sliding sleeve 10, a connecting frame 20 slidably mounted on the horizontal sleeve 19, the connecting frame 20 being rotatably connected to the pressure roller 22, and the connecting frame 20 being connected to the sliding sleeve 10 via a third columnar spring 21; the side of the connecting frame 20 is rotatably connected to the second abutment shaft 23; two sets of guide surfaces 2401 are symmetrically arranged on the trigger 24, and the second abutment shaft 23 cooperates with the guide surfaces 2401 to enable the two sets of connecting frames 20 to move away from each other; furthermore, two sets of parallel vertical surfaces are provided on the side of the trigger 24.

[0029] In the initial state, the second abutting shaft 23 is in contact with the vertical surface, so that the two sets of connecting frames 20 are far apart from each other and the two sets of pressure rollers 22 are far apart from each other. At the same time, the second convex shaft 16 is embedded in the limiting groove 1702, so that the position of the sliding sleeve 10 relative to the deflection frame 4 is constant. This makes the pressure plate 14, the horizontal shaft 15, and the two sets of pressure rollers 22 synchronously separate. In the process of preventing fabric from falling, the fabric can pass between the pressure plate 14, the horizontal shaft 15, and the two sets of pressure rollers 22 by placing the fabric vertically, reducing the difficulty of placing the fabric.

[0030] Once the fabric is in place, pushing the push-pull frame 18 allows the sliding sleeve 10 to move along the length of the deflection frame 4. During this movement, the sliding sleeve 10 will cause the limiting member 17 to move and separate from the second convex shaft 16. At this time, the pressure plate 14 will move towards the horizontal axis 15, thereby clamping the fabric between them. As the sliding sleeve 10 continues to move, the second abutting shaft 23 will separate from the upper trigger member 24 along the vertical plane and guide surface 2401. At this time, under the pull of the third columnar spring 21, the two sets of connecting frames 20 will move closer to each other, allowing the two sets of pressure rollers 22 on the two sets of connecting frames 20 to move separately. The pressure roller 22 acts on both sides of the fabric to generate tension on the fabric as it moves downward. Specifically, the shaft of the pressure roller 22 is not perpendicular to the side of the fabric. More specifically, the end of the shaft of the pressure roller 22 facing the side wall of the fabric is in front of the other end as the pressure roller 22 moves downward. This allows friction to be generated between the pressure roller 22 and the fabric as it moves downward. This friction generates lateral and longitudinal tension on the fabric, so that when the upper end of the fabric is fixed, the movement of the pressure roller 22 can generate tension on the fabric, ensuring that the fabric does not wrinkle when both ends of the fabric are fixed.

[0031] It should be noted that the friction force mentioned above is relatively small and is mainly used to eliminate wrinkles on the fabric that cannot be eliminated by gravity on their own. This will not cause excessive stretching of the fabric, which could lead to fabric deformation and prevent errors in moisture absorption performance testing caused by fabric deformation.

[0032] Furthermore, when the sliding sleeve 10 moves downward to the point where the second abutment shaft 23 abuts against the lower trigger member 24, it drives the deflection frame 4 to deflect, enabling the first clamping assembly to clamp the lower end of the fabric. Subsequently, the sliding sleeve 10 is further driven to move so that the second abutment shaft 23 can move to the vertical surface on the side of the lower trigger member 24, thereby allowing the pressure roller 22 to separate from the fabric. This prevents the pressure roller 22 from interfering with the fabric during the water absorption process. At the same time, during the process of absorbing water and draining free water, since the pressure roller 22 is in a state of separation from the fabric, the fabric can hang down naturally, further preventing the fabric from bending and wrinkling in the middle and lower sections due to gravity after absorbing water, and allowing the free water on the fabric to drain quickly.

[0033] As an embodiment of the present invention, a method for testing the performance of a moisture-wicking fabric using the aforementioned performance testing device is also provided, comprising the following steps: Step 1: The deflection frame 4 is brought into a vertical position by the drive structure, and then the fabric to be tested is passed through the first clamping assembly and the tensioning assembly; Step 2: Push the tensioning component downwards so that the first clamping component can clamp one end of the fabric and tension the fabric as the tensioning component moves along the length of the deflection frame 4. Step 3: When the tensioning component is about to move to the lower end of its stroke, place the other end of the fabric into the second clamping component. Then, drive the deflection frame 4 to deflect through the drive structure, so that the second clamping component clamps the other end of the fabric and deflects the deflection frame 4 at a predetermined angle. Finally, let the tensioning component continue to move until the tensioning component separates from the fabric. At this time, the testing machine body 1 weighs the fabric. Step 4: Control the horizontal plate 3 to move towards the inside of the testing machine body 1, so that the liquid in the testing machine body 1 gradually submerges the horizontal plate 3; Step 5: Raise the horizontal plate 3 to the initial position, and then make the deflection frame 4 vertical through the drive structure. At this time, the second clamping component is separated. In this state, the fabric is in a natural hanging state. In this state, the fabric is allowed to drip for a certain period of time, and then the fabric is weighed to obtain the moisture absorption of the fabric.

Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.

The performance testing device for moisture-absorbing fabric according to claim 7, characterized in that, The elastic tension structure includes a horizontal sleeve disposed on the sliding sleeve, a connecting frame slidably mounted on the horizontal sleeve, the connecting frame being rotatably connected to the pressure roller, and the connecting frame being connected to the sliding sleeve by a third cylindrical spring; the side of the connecting frame being rotatably connected to the second abutment shaft; two sets of guide surfaces are symmetrically disposed on the trigger member, and the second abutment shaft cooperates with the guide surfaces to enable the two sets of connecting frames to move away from each other.

10. A method for testing the performance of a moisture-wicking fabric using the performance testing device for moisture-wicking fabrics as described in any one of claims 1 to 9, characterized in that, Includes the following steps: Step 1: The deflection frame is brought into a vertical position by the drive structure, and then the fabric to be tested is passed through the first clamping assembly and the tensioning assembly; Step 2: Push the tensioning component downwards so that the first clamping component can clamp one end of the fabric, and the tensioning component can tension the fabric as it moves along the length of the deflection frame. Step 3: When the tensioning component is about to move to the lower end of its stroke, place the other end of the fabric into the second clamping component. Then, drive the deflection frame to deflect through the drive structure, so that the second clamping component clamps the other end of the fabric and deflects the deflection frame at a predetermined angle. Finally, let the tensioning component continue to move until the tensioning component separates from the fabric. At this time, the testing machine weighs the fabric. Step 4: Control the horizontal plate to move towards the inside of the testing machine body, so that the liquid in the testing machine body gradually submerges the horizontal plate; Step 5: Raise the horizontal plate to the initial position, and then use the drive structure to make the deflection frame vertical. At this time, the second clamping component separates. In this state, the fabric is in a natural hanging state. In this state, allow the fabric to drip for a certain period of time, and then weigh the fabric to determine the moisture absorption of the fabric.
