Technical Field

[0001] The invention relates to the technical field of textile testing, in particular to a device for testing the heat and moisture transfer performance of polyester fiber textiles. Background Art

[0002] Polyester fiber textiles are synthetic fibers obtained by spinning polyesters that are polycondensed from organic dibasic acids and diols. Polyester fibers are popular for their durability, but the quality of polyester fibers requires not only durability, but also the heat and moisture transfer properties of polyester fiber textiles.

[0003] Thermal and moisture transfer performance is a method of exploring the correspondence between the thermal and moisture comfort control level and the stimulated color change, which is used to determine whether the material has the effect of quickly absorbing moisture and dissipating sweat when sweating and keeping warm when not sweating.

[0004] For example, the document with application number: 202210458726.4 discloses a method for preparing pine cone-like fabric and a performance testing device, and specifically discloses a blade that can automatically open and close according to the humidity of the environment to accelerate the heat transfer between the human body, clothing, and the environment.

[0005] In the above technical solution, the fabric needs to be stretched and laid flat on top of the testing device. At this time, the tightness of the fabric needs to be adjusted by an external clamping device. When the clamping device directly presses down and fixes the fabric, the clamping device needs to press down on the edge of the fabric. When the moisture and heat transfer performance is tested, the contact area between the fabric and the clamping device will produce a certain amount of blurring, and due to the presence of the clamping device, it is difficult to obtain a more accurate result at this area. Summary of the invention

[0006] The purpose of the present invention is to provide a device for testing the heat and moisture transfer performance of polyester fiber textiles.

[0007] The technical problem solved by the present invention is to solve the problem in the prior art that when the clamping surface of the clamping device is parallel to the textile fabric, the textile fabric is stained onto the clamping surface during the test, making it difficult to obtain the results of the clamping surface.

[0008] The present invention can be implemented through the following technical scheme: a device for testing the heat and moisture transfer performance of a polyester fiber textile, comprising a first adsorption plate and a second adsorption plate for clamping the textile, the first adsorption plate and the second adsorption plate are respectively installed at the output end of a power device, and the first adsorption plate and the second adsorption plate are rotatable, and when the first adsorption plate and the second adsorption plate are in a relative position, a cutting device for cutting the textile is installed on the side of the second adsorption plate.

[0009] A further technical improvement of the present invention is that the first adsorption plate is fixedly mounted on the first rotating seat, and the first rotating seat is mounted on the output end of the first rotating motor, and the first rotating motor is mounted on the output end of the first telescopic rod.

[0010] A further technical improvement of the present invention is that the second adsorption plate is fixedly mounted on the stable mounting seat, and the stable mounting seat is mounted on the output end of the second rotating motor through the second rotating seat, and the second rotating motor is mounted on the output end of the second telescopic rod.

[0011] A further technical improvement of the present invention is that the cutting device includes a rotary cutter, a rotary cutter rod is further provided at the output end of the second rotating motor, and the rotary cutter is fixedly mounted at the output end of the rotary cutter rod, and an angle difference exists between the rotary cutter rod and the second adsorption plate.

[0012] A further technical improvement of the present invention is that the first telescopic rod is fixedly mounted on the output end of the top support frame, a fan support seat is also arranged on the top support frame, and a blower is installed on the side of the fan support seat facing the textile.

[0013] A further technical improvement of the present invention is that a connecting rope base is fixedly installed on the fan support seat, a traction rope is arranged on the connecting rope base, and the traction rope is retractable.

[0014] A further technical improvement of the present invention is that a first rotating roller and a second rotating roller are rotatably arranged on the top support frame, an end connecting roller is rotatably arranged on the first rotating seat, the traction rope is fixedly installed on the second rotating roller, and the traction rope passes through the end connecting roller and the first rotating roller.

[0015] A further technical improvement of the present invention is that it also includes a test base plate, which is installed below the textile and has an adjustable height.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present application adopts a first adsorption plate and a second adsorption plate to clamp the textile. Then, the present application rotates the first adsorption plate and the second adsorption plate respectively so that the clamping surfaces of the first adsorption plate and the second adsorption plate on the textile can be changed from an original parallel state to a vertical state. During this process, when the textile is tested and the textile is smudged, there is a certain pulling force at the bending part of the clamping surface of the textile, which affects the speed and effect of the smudge. At the same time, the clamping surface in the vertical state can directly detect only the upper surface of the textile during detection, thereby reducing the result interference problem caused by the clamping surface.

[0018] 2. In the present application, the first rotating roller, the second rotating roller and the end connecting roller cooperate to make it possible for the blower to move longitudinally when the clamping height of the textile is adjusted through the movement of the end connecting roller. Therefore, the distance between the blower and the textile can be adjusted, and the textile can be directly tested as needed. The force of the wind can also be simulated, thereby realizing the detection of the heat and moisture transfer effect of the textile in the presence of wind. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0026] See also Figure 1-4As shown, a device for testing the heat and moisture transfer performance of polyester fiber textiles comprises a top support frame 1, which is fixedly mounted on a frame, wherein a fan limit rod 16 is slidably arranged in the middle of the top support frame 1, wherein a fan support seat 15 is fixedly mounted on the end of the fan limit rod 16, wherein a plurality of groups of blowers 14 are fixedly mounted on one end of the fan support seat 15 away from the top support frame 1, wherein the distance between the fan support seat 15 and the top support frame 1 is adjustable, and the blower 14 and corresponding testing equipment are used to sense the heat and moisture transfer performance of the textile.

[0027] At the same time, two groups of clamping devices for clamping the textile are installed on the top support frame 1. The clamping devices act on the two ends of the textile respectively, and the clamping function of the two ends of the textile is realized by using the clamping devices.

[0028] The clamping device includes a first telescopic rod 2 and a second telescopic rod 13, wherein a first supporting seat 3 is fixedly installed at the output end of the first telescopic rod 2, wherein a first rotating motor 4 is arranged inside the first supporting seat 3, and a first rotating seat 6 is rotatably arranged at the output end of the first rotating motor 4, wherein a first adsorption disk 5 is fixed at the end of the first rotating seat 6. When in use, the height of the first adsorption disk 5 can be controlled by the first telescopic rod 2, and the first rotating seat 6 can be controlled to rotate by starting the first rotating motor 4, so as to control the position and clamping angle of the first adsorption disk 5, wherein the first adsorption disk 5 is circular, and an electromagnet is fixed inside the first adsorption disk 5, and the metal plate can be loosened and adsorbed by the loss of power and the energization of the electromagnet, so that one end of the textile can be clamped and fixed under the joint action of the metal plate and the first adsorption disk 5.

[0029] The output end of the second telescopic rod 13 is fixedly installed with a second supporting seat 12, and a second rotating motor is fixed at the end of the second supporting seat 12, wherein the output end of the second rotating motor is fixed with a second rotating seat 11, and a second suction plate 8 and a rotary cutter 7 are respectively installed on the second rotating seat 11 through a stable mounting seat 7 and a rotary cutter 7 are fixedly installed through a rotary cutter rod 10. When in use, the second suction plate 8 is circular, and an electromagnet is fixed inside the second suction plate 8. The metal plate can be loosened and adsorbed by the loss of power and power of the electromagnet, so that the other end of the textile can be clamped and fixed under the joint action of the metal plate and the second suction plate 8. At the same time, when the second rotating motor drives the second rotating seat 11 to rotate, the rotary cutter 9 can be driven to rotate. At this time, since the rotary cutter rod 10 is inclined, when the rotary cutter rod 10 rotates, the end height of the rotary cutter 9 will be lowered, which is convenient for the rotary cutter 9 to directly cut the textile and cut the textile, and the second telescopic rod 13 can control the height of the second suction plate 8.

[0030] In the above technical scheme, when the first adsorption plate 5 and the second adsorption plate 8 rotate relative to each other, the adsorption surfaces of the first adsorption plate 5 and the second adsorption plate 8 are changed from the original downward setting to a relative setting. At this time, the textile becomes in a state of smooth upper surface, and the adsorption surfaces of the first adsorption plate 5 and the second adsorption plate 8 are changed to a vertical setting compared with the original. It is only necessary to consider the influence of the thickness of the first adsorption plate 5 on the textile. At the same time, the first adsorption plate 5 and the second adsorption plate 8 that are relatively set have the textile clamping part facing vertically downward, so they are generally not involved in the test process. In addition, due to the adsorption and clamping of the electromagnet and the metal plate, the possibility of blurring of the textile clamping part during the test can be reduced. It is only necessary to judge its vertical upward function, which is convenient and simple.

[0031] When the first adsorption plate 5 and the second adsorption plate 8 rotate relative to each other, the tightness of the textile clamped between the first adsorption plate 5 and the second adsorption plate 8 will change, making it smaller. Therefore, in the present application, the first telescopic rod 2 and the second telescopic rod 13 are respectively installed on their respective mobile modules 17, and a mobile slider 18 is installed at the output end of the mobile module 17 for installing the first telescopic rod 2 and the second telescopic rod 13. Therefore, in the present application, the mobile module 17 is a power telescopic rod or a screw rod assembly that can move laterally, so as to adjust the tightness of the textile and ensure that the tightness of the textile is in a stable state.

[0032] In order to control the longitudinal movement of the blower 14 and adjust the position of the blower 14, a connecting rope base 23 is fixedly installed on the blower support seat 15, a first rotating roller 19 and a second rotating roller 21 are fixedly installed on the top support frame 1, and end connecting rollers 22 are fixedly installed on the first rotating seat 6 and the second rotating seat 11, respectively, so the traction rope 20 is fixedly installed on the second rotating roller 21, and the traction rope 20 is fixedly installed on the connecting rope base 23 through the end connecting roller 22 and the first rotating roller 19 in sequence. Therefore, when in use, the height of the first adsorption plate 5 and the second adsorption plate 8 is controlled by starting the first telescopic rod 2 and the second telescopic rod 13, and the height of the connecting roller 22 is controlled in real time, so as to realize the control of the height of the blower support seat 15, facilitate the control of the height of the blower 14, and facilitate the use of the blower 14 to act on the textile. Therefore, the basic parameters can be adjusted as needed.

[0033] In order to detect the textile, the heat and humidity range of the test textile are detected by the sensor and camera on the test base plate 26. The sensor is used to detect the temperature of the textile when it passes through the blower 14, and the camera is used to visually identify the humidity range on the textile to determine whether the quality problems of the textile can be quickly obtained when a water dripping test is performed on a partial area of ​​the textile.

[0034] A first rotating rod 27 is rotatably installed at the bottom of the test base plate 26, wherein the first rotating rod 27 and the second rotating rod 29 are rotatably connected, and the second rotating rod 29 is rotatably installed on the support base 24, and the support base 24 is fixedly installed on the frame, and is rotatably installed on a sliding seat at the rotational connection portion of the first rotating rod 27 and the second rotating rod 29, and the sliding seat is installed at the output end of the bidirectional movable module 28, wherein the bidirectional movable module 28 includes a motor-driven bidirectional screw, and a sliding seat is threadedly arranged on the bidirectional screw, and the sliding seat and the fixed shell of the bidirectional movable module 28 are slidably connected, which is used to realize the distance adjustment of the rotational connection portion of the first rotating rod 27 and the second rotating rod 29, thereby realizing the longitudinal support adjustment of the test base plate 26, so the support base 24 and the bidirectional movable module 28 are slidably connected through the sliding limit rod 25, which is used to realize the longitudinal movement of the bidirectional movable module 28.

[0035] When the present invention is used, the textile is first moved from under the first adsorption plate 5 and the second adsorption plate 8 until the textile is placed under the first adsorption plate 5 and the second adsorption plate 8, and then the first adsorption plate 5 and the second adsorption plate 8 are longitudinally moved to achieve the first adsorption plate 5 and the second adsorption plate 8 to adsorb and fix the two ends of the textile respectively, and then the first rotating motor 4 and the second rotating motor are started to drive the first adsorption plate 5 to rotate and the second adsorption plate 8 to rotate respectively, and at this time, the tightness of the textile is maintained under the action of the moving module 17 to ensure that the textile can be tested for heat and moisture transfer performance;

[0036] During this process, when the second rotating motor drives the second rotating seat 11 to rotate, the inclined peeling rod 10 is driven to rotate, so that the height of the peeling knife 9 is reduced until the peeling knife 9 acts on the textile, and the textile is automatically cut. At the same time, the adsorption surfaces of the first adsorption plate 5 and the second adsorption plate 8 are arranged relatively to each other, so that the upper surface of the textile can be used as the detection surface, and the clamping surface is set to be longitudinal to avoid interference with the upper surface caused by the longitudinal clamping surface;

[0037] When the first adsorption plate 5 or the second adsorption plate 8 is adsorbed, a metal block is placed on the frame, so the textile passes between the metal block and the first adsorption plate 5. When the textile is clamped, the metal plate can be adsorbed through the conduction of the electromagnet. At this time, the textile is clamped between the first adsorption plate 5 and the electromagnet, thereby achieving stable clamping of the textile.

[0038] Subsequently, the bidirectional movable module 28 is activated to drive the contact parts of the first rotating rod 27 and the second rotating rod 29 to adjust the horizontal position, thereby realizing the relative rotation of the first rotating rod 27 and the second rotating rod 29, so as to support the test base plate 26. In this process, the activation of the bidirectional movable module 28 can stably realize the stable movement of the test base plate 26 and reduce the vibration generated during movement.

[0039] When testing the textile, water vapor is blown to the testing area of ​​the textile by the blower 14, and then the structure is tested using the sensors and camera placed on the test base plate 26. That is, the temperature of the textile when it passes through the blower 14 is detected using the sensor, and the humidity range on the textile is visually identified using the camera to determine whether the quality problems of the textile can be quickly detected when a water dripping test is performed on a partial area of ​​the textile.
