Description

Technical Field

[0001] The invention belongs to the field of textile technology, and in particular relates to a yarn tension detection device of a new material for textile use. Background Art

[0002] In the process of the vigorous development of the textile industry, the research and development and application of new material yarns continue to accelerate, becoming a key force in promoting innovation and upgrading of the industry. New yarns such as high-performance fiber yarns, smart color-changing yarns, and functional antibacterial yarns continue to emerge. These new material yarns are widely used in high-end textiles and clothing, medical protection, aerospace, smart wearables and other fields with their unique performance advantages.

[0003] As the requirements for textile material performance in various fields continue to increase, yarn quality and performance testing have become the core link to ensure product quality, and tension testing, as an important indicator to measure yarn quality, has received increasing attention from the industry. However, traditional yarn tension testing devices have many limitations, and the following technical problems usually occur during use:

[0004] 1. Limited tension provision method: Some traditional devices use simple mechanical stretching methods, which can provide limited tension. For some high-strength new material yarns, they cannot produce sufficient tensile deformation, and cannot fully detect the performance of these yarns when subjected to large tension, resulting in one-sided test results;

[0005] 2. Poor adaptability of clamping components: New material yarns of different thicknesses and materials have very different characteristics. However, traditional clamping components have a single specification. During the clamping process, either the yarn cannot be firmly fixed, causing the yarn to slip during detection, affecting the detection accuracy; or the clamping force is too large, causing damage to the soft or fragile yarn, which also makes the detection results unreliable and difficult to adapt to a wide range of detection;

[0006] 3. Insufficient consideration of environmental factors: The performance of yarn will be significantly affected by the ambient temperature and humidity, but most existing testing devices are not set up with different temperature and humidity gradient environments, and can only be tested under conventional conditions. It is impossible to obtain the tensile performance data of the yarn under various environmental conditions, so that the test results cannot truly reflect the performance of the yarn in actual use scenarios, which is not conducive to a comprehensive evaluation of the yarn quality. Summary of the invention

[0007] The purpose of the present invention is to provide a new material yarn tension detection device for textile use, which can softly clamp yarns of different types, firmly fix the yarns, and avoid causing hard damage to the yarns, in response to the problems raised in the above background technology.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] A new material yarn tensile testing device for textiles, comprising:

[0010] A detection platform;

[0011] A clamping mechanism, two groups of which are provided and arranged oppositely, for softly clamping yarns of different models. The clamping mechanism includes a support block, the upper end of the support block is fixedly connected with a support rod, the upper end of the support rod is fixedly connected with a mounting ring, and the inner wall of the mounting ring is fixedly connected with a plurality of U-shaped frames distributed in a circumferential array. A clamping ring is fixedly connected between the plurality of U-shaped frames. The clamping ring includes a plurality of arc-shaped blocks distributed in a circumferential array and a rotating shaft rotatably connected between adjacent two arc-shaped blocks. A clamping soft rod is fixedly connected to the rotating shaft. On the side wall of the clamping soft rod away from the center position of the detection platform, two fixing rods are fixedly connected. Two inclined plates are fixedly connected to the two fixing rods. An elastic airbag is fixedly connected between the two inclined plates. The end of the clamping soft rod is fixedly connected to the outer wall of the elastic airbag. A pump air unit for inflating and deflating the elastic airbag is provided on the support block;

[0012] A detection mechanism for driving the two groups of clamping mechanisms to move closer to or away from each other to realize the tensile testing of the yarn.

[0013] Preferably, the pump air unit includes an air pump fixedly connected to the upper end of the support block. Two air delivery pipes are connected to the air pump. One of the air delivery pipes connects the air pump to the outside, and the other air delivery pipe connects the air pump to the elastic airbag.

[0014] Preferably, the detection mechanism includes a bidirectional first threaded rod rotatably connected inside the detection platform. Threads with opposite spiral directions are provided on the two side rod bodies of the first threaded rod. Two sliding grooves are opened at the upper end of the detection platform. The two threaded parts of the first threaded rod are respectively located in the sliding grooves on both sides. Sliding blocks are threadedly connected to the two threaded parts of the first threaded rod. The sliding blocks are fixedly connected to the support blocks at the corresponding positions. A first motor for driving the first threaded rod is fixedly connected to one end of the detection platform.

[0015] Preferably, a dust-proof mechanism is further provided above the detection platform to prevent dust from affecting the tensile testing of the yarn. The dust-proof mechanism includes a fixing plate fixedly connected to the side wall of the detection platform. A second threaded rod is rotatably connected to the fixing plate. A lifting block is threadedly connected to the second threaded rod. A dust-proof cover is fixedly connected to the side wall of the lifting block. A second motor for driving the second threaded rod is fixedly connected to the lower end of the fixing plate.

[0016] Preferably, a limiting rod is fixedly connected to the upper end of the fixing plate, and the limiting rod passes through and is slidably connected to the lifting block.

[0017] Preferably, a ventilation mechanism is provided between the two side walls of the dust cover to prevent the humidity in the working environment inside the dust cover from affecting the detection result during the tensile force detection process. The ventilation mechanism includes ventilation ducts fixedly connected to the two side walls of the dust cover. A fan is provided in one of the ventilation ducts, and a dust-proof filter screen is provided on the ventilation duct where the fan is located.

[0018] Preferably, a humidity sensor is fixedly connected to the inner wall of the dust cover, and a PLC controller is fixedly connected to the outer wall of the dust cover.

[0019] Preferably, the PLC controller adjusts the power of the fan according to the humidity data inside the dust cover fed back by the humidity sensor.

[0020] Compared with the existing technology, the advantages of this new textile material yarn tensile force detection device are as follows:

[0021] 1. By setting the clamping mechanism, the present invention can form an adaptively adjustable clamping ring through the connection of a plurality of arc-shaped blocks distributed in a circumferential array with the rotating shaft, cooperate with the soft clamping rod and the elastic airbag controlled by inflation and deflation, and can perform soft clamping on yarns of different models, which can not only firmly fix the yarn, but also avoid causing hard damage to the yarn, ensure the integrity of the yarn during the detection process, and provide a strong guarantee for obtaining accurate tensile force detection results. For example, when detecting a slender and fragile new fiber yarn, the inflation amount of the elastic airbag can be precisely controlled to adjust the clamping force of the clamping rod, which can not only ensure that the yarn does not slip, but also prevent the yarn from being damaged due to excessive clamping.

[0022] 2. By setting the detection mechanism, the present invention can utilize the cooperation of the bidirectional first threaded rod and the slider, driven by the first motor, to precisely control the relative movement of the two clamping mechanisms, thereby realizing the precise adjustment and stable detection of the yarn tensile force, meeting the requirements of different detection standards for the magnitude and change rate of the tensile force, and improving the accuracy and reliability of the detection. For example, when simulating the stress situation of the yarn in the actual textile process, the moving speed and distance of the clamping mechanism can be precisely adjusted to simulate different tensile force change curves, providing an accurate basis for evaluating the performance of the yarn in actual use.

[0023] 3. By setting up a dust-proof mechanism, the present invention can drive the second threaded rod through the second motor to drive the lifting of the dust-proof cover, effectively preventing dust from affecting the yarn tension detection. At the same time, ventilation mechanisms are provided on both side walls of the dust-proof cover. Combined with the humidity sensor and the PLC controller, the fan power can be adjusted in real time according to the humidity data inside the dust-proof cover, avoiding the interference of humidity on the detection result, creating stable and suitable environmental conditions for the detection, and further improving the credibility of the detection result. For example, when detecting in an environment with high humidity, the humidity sensor detects that the humidity exceeds the standard, and the PLC controller immediately controls the fan to increase the power, accelerate ventilation and air exchange, and reduce the humidity inside the dust-proof cover to ensure that the detection is not affected by the humid environment.

[0032] The following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0033] Embodiment: Refer to Figures 1 to 6, a new material yarn tensile testing device for textiles, comprising:

[0034] A testing platform 1, serving as the basic support structure of the entire device, providing a platform for the installation and operation of other components, and ensuring the stable operation of each mechanism during the testing process;

[0035] A clamping mechanism 2, with two sets of the clamping mechanism 2 arranged oppositely, used for softly clamping yarns of different models. The clamping mechanism 2 includes a support block 21. The upper end of the support block 21 is fixedly connected to a support rod 22. The upper end of the support rod 22 is fixedly connected to an installation ring 23. The inner wall of the installation ring 23 is fixedly connected to a plurality of U-shaped frames 24 distributed in a circumferential array. A clamping ring 25 is fixedly connected between the plurality of U-shaped frames 24. The clamping ring 25 includes a plurality of arc-shaped blocks 251 distributed in a circumferential array and a rotating shaft 252 rotatably connected between adjacent two arc-shaped blocks 251. This structural design enables the clamping ring 25 to make a certain degree of adaptive adjustment according to the thickness and shape of the yarn, improving the versatility and stability of clamping. A clamping soft rod 26 is fixedly connected to the rotating shaft 252. The clamping soft rod 26 is made of a soft material, which can avoid causing hard damage to the yarn when clamping the yarn, ensure the integrity of the yarn during the testing process, and thus ensure the accuracy of the testing results. On one side wall of the clamping soft rod 26 away from the center position of the testing platform 1, two fixed rods 27 are fixedly connected. Two inclined plates 28 are fixedly connected to the two fixed rods 27. A specific space is formed between the two inclined plates 28 for installing an elastic airbag 29. An elastic airbag 29 is fixedly connected between the two inclined plates 28. The end of the clamping soft rod 26 is fixedly connected to the outer wall of the elastic airbag 29. A pump air unit for inflating and deflating the elastic airbag 29 is provided on the support block 21;

[0036] When the elastic airbag 29 is inflated, its volume expands, pushing one end of the clamping soft rod 26 to move outward, so that the other end of the clamping soft rod 26 moves inward, realizing the clamping and fixing of the yarn; when the elastic airbag 29 is deflated, the elastic element inside the elastic airbag 29 makes it return to its initial state, so as to flexibly adjust the clamping force according to the characteristics of the yarn. For example, for softer yarns, the inflation amount of the elastic airbag 29 can be appropriately reduced to avoid damaging the yarn due to excessive clamping force; for harder and less deformable yarns, the inflation amount can be increased to ensure firm clamping.

[0037] Specifically, the air pump unit includes an air pump 4 fixedly connected to the upper end of the support block 21. Two air delivery pipes 41 are connected to the air pump 4. One of the air delivery pipes 41 connects the air pump 4 to the outside, and the other air delivery pipe 41 connects the air pump 4 to the elastic airbag 29. The air pump 4 adopts a model with high precision and good stability, which can accurately control the speed and volume of inflation and deflation, ensuring precise adjustment of the clamping force.

[0038] The detection mechanism 3 is used to drive the two clamping mechanisms 2 to move closer to or away from each other to realize the tensile force detection of the yarn. The detection mechanism 3 includes a bidirectional first threaded rod 31 rotatably connected inside the detection platform 1. The two sides of the threaded rod of the first threaded rod 31 are provided with threads with opposite spiral directions. When the first threaded rod 31 rotates, the components at the two threaded sides will move in opposite directions. Two chutes 32 are opened at the upper end of the detection platform 1. The chutes 32 provide a moving track for the sliders 33, ensuring that the sliders 33 can only move horizontally in a predetermined direction, thereby ensuring the stable and accurate movement of the clamping mechanism 2. The two threaded sides of the first threaded rod 31 are respectively located in the two chutes 32 on both sides. The two threaded sides of the first threaded rod 31 are both threadedly connected with sliders 33. The sliders 33 are fixedly connected to the support blocks 21 at the corresponding positions. One end of the detection platform 1 is fixedly connected with a first motor 34 for driving the first threaded rod 31.

[0039] The first motor 34 serves as the power source of the detection mechanism 3. By driving the first threaded rod 31 to rotate, the mutual approach or separation movement of the two clamping mechanisms 2 is indirectly realized, and a tensile force is applied to the yarn for detection.

[0040] Above the detection platform 1, there is also a dust-proof mechanism 5 for preventing dust from affecting the tensile force detection of the yarn. The dust-proof mechanism 5 includes a fixing plate 51 fixedly connected to the side wall of the detection platform 1. The fixing plate 51 provides an installation basis for other components of the dust-proof mechanism, ensuring that the entire dust-proof mechanism can be stably installed above the detection platform 1. A second threaded rod 52 is rotatably connected to the fixing plate 51. The second threaded rod 52 rotates under the drive of a motor to realize the up and down movement of the lifting block 53. A lifting block 53 is threadedly connected to the second threaded rod 52. The lifting block 53 moves up and down in the vertical direction as the second threaded rod 52 rotates, thereby driving the dust-proof cover 54 to move up and down. A dust-proof cover 54 is fixedly connected to the side wall of the lifting block 53. The dust-proof cover 54 can cover the yarn and the clamping mechanism during the detection process, preventing external dust from entering and avoiding interference with the yarn tensile force detection result. A second motor 55 for driving the second threaded rod 52 is fixedly connected to the lower end of the fixing plate 51. The second motor 55 serves as the power source of the dust-proof mechanism 5, driving the second threaded rod 52 to rotate to realize the lifting operation of the dust-proof cover 54.

[0041] Specifically, a limiting rod 6 is fixedly connected to the upper end of the fixing plate 51. The limiting rod 6 is slidably connected through the lifting block 53. The function of the limiting rod 6 is to limit the movement track of the lifting block 53, prevent the lifting block 53 from rotating or shifting during the lifting process, ensure that the dust-proof cover 54 can move up and down smoothly, and improve the stability and reliability of the dust-proof mechanism.

[0042] A ventilation mechanism 7 is provided between the two side walls of the dust-proof cover 54 to prevent the humidity in the working environment inside the dust-proof cover 54 from affecting the detection result during the tensile force detection. The ventilation mechanism 7 includes ventilation ducts 71 fixedly connected to the two side walls of the dust-proof cover 54. A fan 72 is provided in one of the ventilation ducts 71. The fan 72 serves as a ventilation power source to promote the flow of air in the ventilation ducts 71, realizing the rapid update of the air inside the dust-proof cover 54. A dust-proof filter screen is provided on the ventilation duct 71 where the fan 72 is located. The dust-proof filter screen can prevent external dust from entering the dust-proof cover 54 through the ventilation duct 71, maintaining a clean environment inside the dust-proof cover 54 while ensuring the ventilation effect.

[0043] Specifically, a humidity sensor 8 is fixedly connected to the inner wall of the dust-proof cover 54, and a PLC controller 9 is fixedly connected to the outer wall of the dust-proof cover 54.

[0044] Specifically, the PLC controller 9 adjusts the power of the fan 72 according to the humidity data inside the dust-proof cover 54 fed back by the humidity sensor 8. When the humidity sensor 8 detects that the humidity inside the dust-proof cover 54 is too high, the PLC controller 9 controls the fan 72 to increase the power and accelerate the ventilation speed, so that the humid air inside the dust-proof cover 54 is discharged faster, reducing the humidity. When the humidity sensor 8 detects that the humidity inside the dust-proof cover 54 is too low, the PLC controller 9 controls the fan 72 to reduce the power and decrease the ventilation volume, maintaining a suitable humidity environment inside the dust-proof cover 54 and ensuring that the yarn tensile force detection result is not interfered by humidity factors.

[0045] The functional principle of the present invention can be elaborated through the following operation mode:

[0046] Before performing the yarn tensile test, first adjust the inflation volume of the elastic airbag 29 through the air pump unit according to the model and characteristics of the yarn, so that the clamping soft rod 26 of the clamping mechanism 2 is adjusted to an appropriate clamping force. Place the yarn between the two sets of clamping mechanisms 2 and clamp and fix it. Start the second motor 55 of the dust-proof mechanism 5 to lower the dust-proof cover 54 to cover the yarn and the clamping mechanism 2 to prevent dust from entering. Then start the first motor 34 of the detection mechanism 3. The first motor 34 drives the first threaded rod 31 to rotate, driving the two sets of clamping mechanisms 2 to move away from each other, applying a tensile force to the yarn for testing. During the testing process, the humidity sensor 8 monitors the humidity inside the dust-proof cover 54 in real time. If the humidity is abnormal, the PLC controller 9 adjusts the power of the fan 72 according to the humidity data, and adjusts the humidity inside the dust-proof cover 54 through the ventilation mechanism 7 to ensure a stable testing environment, so as to obtain an accurate yarn tensile test result.

[0047] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
