[0001] The present application relates to the technical field of fiber testing, and in particular to an intertwining degree testing device and an intertwining degree testing method. Background Art

[0002] In the field of modern materials science and industrial production, the entanglement characteristics of many fiber materials play a vital role in the performance of their final products. The entanglement is directly related to key indicators such as the structural integrity, mechanical properties and processing adaptability of fiber products.

[0003] In the past, the test of entanglement mainly relied on manual operation combined with simple universal measuring tools. However, this method has significant defects. From the perspective of manual operation, human subjective factors greatly affect the accuracy and reliability of the test results.

[0041] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0042] In the field of modern materials science and industrial production, the entanglement characteristics of many fiber materials play a vital role in the performance of their final products. The entanglement is directly related to key indicators such as the structural integrity, mechanical properties and processing adaptability of fiber products.

[0043] In the past, the test of intertwining degree mainly relied on manual operation combined with simple general measuring tools. However, this method has significant defects. From the perspective of manual operation, human subjective factors greatly affect the accuracy and reliability of the test results. When counting the intertwining points of fiber filaments, operators are easily disturbed by factors such as visual fatigue and distraction, resulting in poor accuracy of test results. Moreover, due to differences in experience and operating habits among different operators, it is difficult to unify the evaluation criteria for intertwining degree, and it is impossible to accurately reflect the actual intertwining degree of fiber filaments.

[0044] Therefore, the existing entanglement test methods are difficult to meet the needs of industrial production and scientific research for high-precision and high-reliability test data. There is an urgent need for a special entanglement test device and a standardized usage method to improve the accuracy and stability of the entanglement test and provide strong technical support for fiber quality control and performance optimization.

[0045] In order to solve the problems described in the related art, the present application provides an intertwining degree testing device and an intertwining degree testing method, including a frame, two clamps, a guide rod, a magnetic induction device and a hook, wherein the two clamps are arranged on one side of the frame, and are used to clamp the two ends of the fiber filaments that are naturally straightened in the vertical direction. The two ends of the guide rod are respectively arranged on the two clamps through a telescopic member, and the guide rod extends along the length direction of the fiber filament. The magnetic induction device is arranged in the guide rod, and the magnetic induction device has magnetism when it is powered on or eliminates magnetism when it is powered off. The hook is sleeved on the guide rod, and the hook faces the direction of the fiber filament. When the telescopic member drives the guide rod to repeatedly approach the fiber filament so that the hook is repeatedly inserted into the fiber filament, the electromagnetic induction device eliminates magnetism, and the hook slides along the length direction of the fiber filament under the action of gravity. When the hook slides along the fiber filament to the intertwining point and stops sliding, the electromagnetic induction device has magnetism to fix the hook by magnetic attraction. The present application provides an intertwining degree testing device and an intertwining degree testing method, which can effectively avoid the error of the intertwining degree test caused by the difference in human operation, so that the test results are more objective and true.

[0046] like Figure 1-Figure 3 As shown, a entanglement test device can be applied to the entanglement test process of filamentary materials such as carbon fiber filaments and glass fiber filaments. The entanglement test device includes a frame 1, which serves as the supporting structure of the entire test device and provides a stable installation foundation and working platform for other components. The frame 1 has sufficient stability to ensure that the accuracy of the test results will not be affected by external interference during the test. In some embodiments, the frame 1 may include a column 11 and a base 12, the column 11 is vertically arranged on the base 12, and other components are arranged on the column 11. The base 12 provides a stable support to prevent the column 11 from tipping over. In other embodiments, the frame 1 can also be an integral frame structure, or other support structures that can ensure stability.

[0047] The intertwining degree testing device also includes two clamps 2, both of which are arranged on the frame 1, and the two clamps 2 are located on the same side of the frame 1, and the two clamps 2 are symmetrically arranged vertically, and the two clamps 2 are respectively used to clamp the two ends of the fiber filaments that are naturally straightened and not stretched in the vertical direction, and the two clamps 2 clamp the two ends of the fiber filaments together to ensure the reliability and stability of the clamping. Since the fiber filaments are in a naturally straightened state under the clamping action of the clamps, when measuring the length of the fiber filaments, the real data of the fiber filament length can be obtained, avoiding the fiber filaments being over-stretched or shortened due to other reasons, which affects the final intertwining degree result.

[0048] The intertwining test device also includes a guide rod 3, which is arranged on the clamp 2 through a telescopic member 4. There are two telescopic members 4, which are symmetrically arranged. The two telescopic members 4 correspond to the two clamps 2 respectively, that is, each clamp 2 is provided with a telescopic member 4. The telescopic member 4 can be arranged on the clamp 2 by bolts or welding. The telescopic member 4 is arranged on one side of the clamp 2. The telescopic member 4 can be extended and retracted. Figure 1 and Figure 3 In the embodiment shown, the telescopic part 4 is telescopic in the x direction, the fixed part of the telescopic part 4 is arranged on the fixture 2, the telescopic part of the telescopic part 4 is close to or away from the fixture 2, and in some embodiments, the telescopic part 4 can be a telescopic rod. The two ends of the guide rod 3 are respectively connected to the telescopic parts of the two telescopic parts 4, and the connection method can be bolted or welded. The guide rod 3 extends along the length direction of the fiber filament. Since the fiber filament is vertically arranged when it is naturally straightened, the guide rod 3 is arranged vertically. The guide rod 3 is cylindrical, and the surface of the guide rod 3 is smooth and wear-resistant, which provides convenience for the hook 5 to slide on the guide rod 3.

[0049] The intertwining degree testing device further comprises a magnetic induction device (not shown in the figure), which is arranged in the guide rod 3. The magnetic induction device has magnetism when powered on or eliminates magnetism when powered off.

[0050] The intertwining degree testing device also includes a hook 5, which is sleeved on the guide rod 3, and the tip of the hook 5 faces the direction of the fiber filament. The tip of the hook 5 is designed so that the tip of the hook 5 can be easily inserted into the fiber filament without being too sharp to cause the fiber filament to break. The material of the hook 5 has certain strength and wear resistance, and can slide smoothly along the guide rod 3 to ensure the accuracy of the result. The hook 5 is a metal material that can be adsorbed by a magnet, such as an iron material. When the magnetic induction device is powered on, the magnetic induction device has magnetism, and the hook 5 and the magnetic induction device are mutually adsorbed under the action of magnetic force. Since the magnetic induction device is arranged in the guide rod 3, it is manifested as the hook 5 and the guide rod 3 are mutually adsorbed and fixed on the guide rod 3. When the magnetic induction device is powered off, the magnetic induction device eliminates magnetism, and there is no longer magnetic adsorption between the hook 5 and the magnetic induction device, which is manifested as the adsorption force between the hook 5 and the guide rod 3 is released, and the hook 5 can slide along the guide rod 3 under the action of its own gravity. The provision of the magnetic induction device in the present application facilitates fixing and releasing the hook hook 5 during the test process to accurately calculate the degree of intertwining.

[0051] The entanglement degree testing device also includes a measuring mechanism (not shown in the figure), which is used to measure the sliding distance of the hook needle 5 inserted into the fiber filament to provide data support for the entanglement degree test.

[0052] When the telescopic part of the telescopic member 4 is close to the clamp 2, Figure 1 and Figure 3 In the embodiment shown, the telescopic part of the telescopic member 4 moves in the x direction, driving the guide rod 3 close to the fiber filament, so that the hook needle 5 set on the guide rod 3 is inserted into the fiber filament. When the hook needle 5 is inserted into the fiber filament, the electromagnetic induction device is powered off to eliminate magnetism, and there is no longer magnetic adsorption between the hook needle 5 and the electromagnetic induction device. At this time, the hook needle 5 can slide downward along the guide rod 3 under the action of gravity. When the hook needle 5 encounters an intertwining point during the sliding process, it stops sliding. At this time, the electromagnetic induction device is powered on and has magnetism. In order to prevent the hook needle 5 from falling, the hook needle 5 is fixed by magnetic attraction to the electromagnetic induction device, and the hook needle 5 is fixed on the guide rod 3 so that the hook needle 5 cannot continue to slide. When the hook needle 5 encounters an intertwining point and stops sliding, the magnetic induction device is powered on to fix the position of the hook needle 5, so that the hook needle 5 can accurately stop at the intertwining point, and then the distance between two adjacent intertwining points can be accurately measured, thereby obtaining more accurate fiber intertwining degree data.

[0053] At this point, the hook needle 5 encounters an intersection point once, and the distance it slides before encountering the intersection point is also measured by the measuring mechanism. The number of times the hook needle 5 encounters the intersection point is recorded as n, where the nth sliding is sliding from the nth position to the n+1th position, and encounters the intersection point for the nth time at the n+1th position. Specifically, when the hook needle 5 encounters the intersection point for the first time, it is in the second position, and the distance the hook needle 5 slides before encountering the intersection point for the first time is the first distance, and the first distance is the distance from the first position to the second position. When the hook needle 5 encounters the intersection point for the second time, it is in the third position, and the distance the hook needle 5 slides before encountering the intersection point for the second time is the second distance, and the second distance is the distance from the second position to the third position. Repeat this process, and divide the sum of the first distance, the second distance, and the nth distance by the number of times n that the intersection point is encountered, and the value obtained is the average distance to encounter an intersection point, that is, the degree of intersection of the fiber filaments. In some embodiments, the hook 5 is sleeved on the guide rod 3 through a sliding member 6. The sliding member 6 is sleeved on the outside of the guide rod 3 in a circular ring shape and can slide along the guide rod 3. The sliding member 6 is made of metal, such as iron material, to ensure that when the electromagnetic induction device is powered on and has magnetism, the sliding member 6 and the electromagnetic induction device are mutually adsorbed under the action of magnetic force. In this embodiment, since the sliding member 6 is made of metal, the material of the hook 5 is not limited to metal, thereby providing a variety of implementation methods. The setting of the sliding member 6 provides a positive support for the sliding of the hook 5 in the fiber filament, avoids jamming during the sliding process that affects the sliding of the hook 5, and ensures the stability of the sliding of the hook 5.

[0054] In some embodiments, the measuring mechanism is configured as a displacement sensor, which can be disposed on the slider 6 or on the hook 5. When the slider 6 slides, the displacement sensor detects the distance the slider 6 slides. The displacement sensor is highly sensitive and can accurately measure the slight position change of the slider 6, thereby ensuring the accuracy of the intertwining test. In other embodiments, the measuring mechanism can also be a scale line, which is disposed on the outer wall of the guide rod 3, and the scale lines are arranged along the length direction of the guide rod 3. The distance the slider 6 slides can be grasped by reading the scale lines of the slider 6 position.

[0055] In some embodiments, the intertwining degree test device further includes a controller (not shown in the figure), which is the core control unit of the entire test device. The displacement sensor and the electromagnetic induction device are both electrically connected to the controller. When the sliding member 6 slides along the guide rod 3, the displacement sensor detects that the state of the sliding member 6 is a sliding state, and sends the sliding state of the sliding member 6 to the controller. When the hook needle 5 encounters an intertwining point and stops the sliding member 6 from sliding, the displacement sensor detects that the state of the sliding member 6 is a stopped sliding state, and sends the stopped sliding state to the controller, so the controller can receive the state of whether the sliding member 6 slides or not in real time. When the controller receives that the state of the sliding member 6 changes from a sliding state to a stopped sliding state, it indicates that the hook needle 5 has encountered an intertwining point, so the controller controls the electromagnetic induction device to be energized with magnetism, so that the sliding member 6 is magnetically fixed to the magnetic induction device.

[0056] When the hook 5 is inserted into the fiber, the electromagnetic induction device is powered off, which can be done manually or by setting a position sensor on the hook 5. The position sensor sends the position of the hook 5 relative to the fiber to the controller. Figure 1 and Figure 3 In the embodiment shown, the position sensor sends the coordinates in the x direction to the controller. When the hook needle 5 is at the position for inserting the fiber filament, the controller controls the electromagnetic induction device to cut off the power.

[0057] The configuration of the controller in this embodiment realizes precise control and automated operation, which not only improves the efficiency but also improves the stability and reliability of the device.

[0058] It should be noted here that, in the interconnection test device provided in this embodiment, the electrical connection between the controller and the magnetic induction device, and the electrical connection between the controller and the measuring mechanism can be a wired connection or a wireless communication connection, as long as they can transmit electrical signals to each other.

[0059] In some embodiments, the clamp 2 includes a first clamping plate 21, a second clamping plate 22 and a clamping member 23. The first clamping plate 21 and the second clamping plate 22 are both arranged on the frame 1. The clamping member 23 is screwed on the first clamping plate 21. The clamping member 23 is close to or far away from the second clamping plate 22, wherein the first clamping plate 21 plays a supporting role for the clamping member 23. Specifically, the clamping member 23 includes a screw rod 231 and a top plate 232. A screw hole is arranged on the first clamping plate 21. The screw rod 231 is screwed correspondingly to the screw hole of the first clamping plate 21. The top plate 232 is connected to one end of the screw rod 231 close to the second clamping plate 22. The top plate 232 is arranged parallel to the second clamping plate 22. The top plate 232 and the screw rod 231 can be connected by a bearing. When the screw rod 231 is rotated, the top plate 232 will not rotate therewith, thereby avoiding damage to the fiber filaments due to the rotation of the top plate 232. The top plate 232 clamps the fiber filaments when it is close to the second clamping plate 22, and releases the fiber filaments when the top plate 232 is away from the second clamping plate 22. The first clamping plate 21 is arranged in parallel with the second clamping plate 22, and is perpendicular to the telescopic direction of the telescopic member 4. In other embodiments, the first clamping plate 21 may not be parallel to the second clamping plate 22, as long as the second clamping plate 22 is perpendicular to the telescopic direction of the telescopic member 4. The telescopic member 4 is arranged on the second clamping plate 22. The arrangement of the first clamping plate 21, the second clamping plate 22 and the clamping member 23 makes the process of clamping the fiber filaments more accurate and stable, and easy to operate.

[0060] The first anti-slip layer is covered on one side of the clamping member 23 close to the fiber filaments, wherein the first anti-slip layer can be at least one of a silicone material or a rubber material, and the first anti-slip layer can be detachably arranged on the clamping member 23, so as to facilitate replacement of the first anti-slip layer. In some embodiments, the first anti-slip layer can be arranged on the clamping member 23 by Velcro, so as to facilitate replacement of the first anti-slip layer.

[0061] A second anti-slip layer is provided on one side of the second clamping plate 22 close to the fiber filaments. The second anti-slip layer is made of at least one of a silicone material or a rubber material. The second anti-slip layer may be the same as or different from the first anti-slip layer. The second anti-slip layer may be detachably provided on the second clamping plate 22. The second anti-slip layer may be provided on the second clamping plate 22 by Velcro, which facilitates replacement of the second anti-slip layer. The provision of the first anti-slip layer and the second anti-slip layer can increase friction to prevent the fiber filaments from falling off during the clamping process, and can also protect the fiber filaments from damage.

[0062] In some embodiments, Figure 2 As shown, a slide groove 221 is provided on one side of the clamp 2 close to the telescopic member 4. The cross section of the slide groove 221 is T-shaped. The extending direction of the slide groove 221 is perpendicular to the length direction of the fiber filament and the telescopic direction of the telescopic member 4. Figure 1In the embodiment shown, the direction of the slide groove 221 is the y direction, and a T-shaped slider corresponding to the slide groove 221 is provided on the telescopic member 4. The slider is located in the slide groove 221 and slides along the slide groove 221. The slide groove 221 can enable the telescopic member 4 to move along the direction in which the fiber filaments are unfolded. Figure 1 In the embodiment shown, the y direction is the direction of the fiber width when the clamp 2 clamps the fiber, that is, the telescopic rod can drive the guide rod 3 to slide in the direction of the fiber width. The guide rod 3 drives the sliding member 6 and the hook 5 to move in the width direction of the fiber, so that when the hook 5 is away from the fiber and inserted into the fiber again, it can be inserted from a new position to avoid being located at the intersection point encountered last time when reinserted, thereby improving the accuracy of the test.

[0063] In some embodiments, the intertwining degree testing device further includes a display screen 7, which is disposed on the top of the frame 1, and the display screen 7 displays the sliding distance of the hook needle 5 inserted into the fiber filament each time. The display screen 7 is electrically connected to the measuring mechanism, and the measuring mechanism detects the moving distance of the hook needle 5 and displays it through the display screen 7. The setting of the display screen 7 can clearly see the sliding distance of the hook needle 5 each time, and when the data displayed on the display screen 7 is greatly different from the sliding distance of the hook needle 5, it can be understood in the first time, and the test can be stopped for maintenance.

[0064] In some embodiments, the intertwining degree testing device also includes a data processing module, which can automatically calculate the intertwining degree of the fiber filaments, and the formula is C=D / n, where D is the sum of the sliding distances of the hook needle 5 before encountering the intertwining point after being inserted into the fiber filaments for multiple times, and n is the number of times the hook needle 5 stops sliding when encountering the intertwining point. The automated calculation of the data processing module improves the test efficiency and accuracy. In the traditional intertwining degree testing method, manual calculation is not only cumbersome and error-prone, but also inefficient. The data processing module can collect data in real time during the test and automatically perform calculations, avoiding subjective errors and time delays in the manual calculation process. It can quickly process a large amount of test data and quickly give accurate intertwining degree results.

[0065] A method for testing the degree of interconnection, applied to the above-mentioned device for testing the degree of interconnection, combined with Figures 1 to 3 The content shown in the figure, the interconnection degree testing method in this application includes the following steps:

[0066] S1: Take a bundle of fiber filaments, make the fiber filaments naturally straighten in the vertical direction without stretching, and fix the two ends of the fiber filaments on the clamps respectively.

[0067] In step S1, after the two ends of the fiber filament are fixed on the clamp 2, it is necessary to ensure that the fiber filament has a certain width after being fixed. Figure 1 In the embodiment shown, the width of the fiber filaments is Figure 1The y direction is flattened to ensure that the subsequent crochet needle 5 can be smoothly inserted into the fiber yarn.

[0068] S2: Insert the hook into the fiber yarn.

[0069] In step S2, the telescopic member 4 is retracted to drive the guide rod 3 to move toward the fiber filament, and the guide rod 3 moves while driving the hook 5 to move, so that the hook 5 is inserted into the fiber filament. The telescopic member 4 can be retracted or extended by holding the guide rod 3 and pulling the guide rod 3 in the direction of the retraction or extension of the telescopic member 4, so that the guide rod 3 drives the telescopic member 4 to retract or extend.

[0070] S3: Allow the hook to slide downwards under the action of gravity.

[0071] In step S3, the electromagnetic induction device is powered off and has no magnetism, the hook needle 5 is released, and the hook needle 5 slides downward along the guide rod 3 under the action of gravity.

[0072] S4: When the hook stops sliding when it encounters the intersection point, the electromagnetic induction device is energized and becomes magnetic and is fixed to the hook by magnetic attraction. The distance the hook slides before it stops sliding is recorded as Dn.

[0073] In step S4, when the hook needle 5 encounters the intersection point, the hook needle 5 stops sliding due to resistance, and at the same time, the electromagnetic induction device is powered on to have magnetism and magnetic attraction with the hook needle 5, fixing the hook needle 5 on the guide rod 3, so that the hook needle 5 cannot slide, and the measuring mechanism measures the distance Dn that the hook needle 5 slides before stopping sliding. The position where the hook needle 5 starts to slide before encountering the intersection point is recorded as the first insertion position, the position of the hook needle 5 when it stops sliding when encountering the intersection point is the first preset position, and the sliding distance Dn is the distance between the first insertion position and the first preset position.

[0074] S5: The crochet hook moves away from the fiber yarn from a first preset position of the fiber yarn, the first preset position being the position where the crochet hook encounters the intersection point this time, and then the crochet hook is reinserted into a second preset position of the fiber yarn, the second preset position being another position at the same horizontal height as the first preset position, and then the electromagnetic induction device is powered off to eliminate the magnetism.

[0075] In step S5, the position where the hook needle 5 encounters the intersection point this time is recorded as the first preset position, and the telescopic member 4 is extended in the manner of step S2 to drive the guide rod 3 to move, and the guide rod 3 drives the hook needle 5 to move from the first preset position in a direction away from the fiber filament. Figure 1 and Figure 3 In the embodiment shown, the direction is -x. When the hook needle 5 is no longer in contact with the fiber, the telescopic member 4 drives the guide rod 3 to move in the opposite direction, and the guide rod 3 drives the hook needle 5 to reinsert into the fiber. The position where the fiber is reinsert is recorded as the second preset position. The second preset position has the same height as the first preset position, but a different lateral position, such as Figure 1 In the embodiment shown, the coordinates of the first preset position and the second preset position along the z direction are the same, but the coordinates along the y direction are different, so as to prevent the hook needle 5 from being inserted into the position of the last intertwining point when reinserting the fiber filament. When the hook needle 5 is inserted into the fiber filament again, the electromagnetic induction device is powered off and demagnetized, and there is no longer magnetic attraction between the hook needle 5 and the magnetic induction device, which is manifested as the attraction between the hook needle 5 and the guide rod 3 is released.

[0076] When measuring the degree of entanglement, the above steps S3 to S5 are repeated repeatedly, that is, the crochet hook 5 is repeatedly inserted into the fiber yarn and slides downward under its own gravity. Each time the crochet hook 5 stops sliding, it means that an entanglement point has been encountered. Therefore, the degree of entanglement can be calculated as C = (D1+…+Dn) / n, wherein D1,…,Dn are the distances the crochet hook 5 slides before encountering an entanglement point each time, and n is the number of times the crochet hook 5 stops sliding when encountering an entanglement point.

[0077] In some embodiments, in step S5, after the crochet hook moves away from the first preset position of the fiber yarn, the telescopic member is slid along the clamp, the sliding direction is perpendicular to the length direction of the fiber yarn and the telescopic direction of the telescopic rod, and then the crochet hook is reinserted into the second preset position of the fiber yarn.

[0078] Specifically, in step S5, the telescopic member 4 can slide along the clamp 2, and the sliding direction is perpendicular to the length direction of the fiber filament and the telescopic direction of the telescopic rod. Figure 1 and Figure 3 In the embodiment shown, the telescopic member 4 drives the guide rod 3 to slide in the y direction, which is the direction of the fiber filament width. The guide rod 3 drives the hook needle 5 to slide in the direction of the fiber filament width, so that when the hook needle 5 is inserted into the fiber filament again, it avoids encountering the intersection point encountered last time, thereby improving the accuracy of the test.

[0079] The present application can make the hook stop accurately at the intersection point of the fiber yarn, and then can accurately measure the distance between two adjacent intersection points, so as to obtain more accurate fiber yarn intersection degree data. The test deviation caused by the operator's experience and operating habits is reduced. The present application provides a unified intersection degree evaluation standard to ensure that no matter which operator performs the test, the true intersection degree of the fiber yarn can be accurately obtained.
