[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0030] Carbon fiber possesses a range of advantages, including light weight, high strength, high modulus, high temperature resistance, and corrosion resistance. Composite materials made from carbon fiber as a reinforcing material have wide applications across various industries. During carbon fiber production, the smoothness of the fiber filaments needs to be tested. However, current techniques rely on the subjective experience of personnel, leading to inconsistent testing standards and low efficiency. Therefore, a standardized testing device is needed.

[0031] This application provides a fiber detection device for detecting fibers wound on a winding spool, comprising a base assembly, a support assembly, an airflow traction assembly, and a collection assembly. By fixing the winding spool with the fibers wound on it to the base assembly, the airflow traction assembly provides power to the fibers, driving them to be conveyed. The fibers on the winding spool pass through the support assembly and are conveyed to the collection assembly. During the fiber conveying process, the condition of the fibers can be clearly understood to complete the detection process.

[0032] The specific embodiments described below are intended to help those skilled in the art understand this embodiment, but this embodiment is not limited to the specific embodiments described below.

[0033] like Figure 1-2 As shown, an exemplary embodiment of this application provides a fiber detection device, including a base assembly 1, a support assembly 2, an airflow traction assembly 3, and a collection assembly 4.

[0034] The base assembly 1 includes a base plate 11 and a fixing member 12. The base plate 11 provides a stable mounting platform for the device. The base plate 11 can be made of metal or high-strength plastic to ensure its stability. In one example, the base plate 11 is cuboid in shape, and its upper surface is a smooth plane. The fixing member 12 is disposed on the base plate 11. In one example, the fixing member 12 is fixed to the base plate 11 by welding or integral molding. In other examples, the fixing member 12 can also be detachably disposed on the base plate 11 by bolts. The fixing member 12 is used to fix the winding spool 5. The fixing method can be nesting, clamping, or snapping. The axis of the winding spool 5 is set at an angle to the base plate 11. In one example, the angle is 90°, which is beneficial for the initial direction of the fiber filament 6 unwinding from the winding spool 5 to be vertical, forming a smooth transition path for subsequent strokes and reducing the bending angle of the fiber filament 6 in the initial stage of unwinding. In some instances, there can be multiple fasteners 12, which are evenly arranged on the base plate 11. Of course, there can also be one or two fasteners 12, and the number of fasteners 12 is set according to actual needs.

[0035] The support assembly 2 includes a frame 21 and filament adsorption rings 22. The frame 21 is formed by welding or integral molding of multiple connecting rods. The frame 21 is fixed to the base plate 11, and the frame 21 can be fixed to the base plate 11 by welding or integral molding. In one example, four connecting rods are respectively fixed at the four corners of the base plate 11, and the other ends of the two connecting rods on each side are fixed. After fixing, a horizontal connecting rod is used to connect the connecting rods at both ends. The filament adsorption rings 22 are set on the frame 21, and the number and position of the filament adsorption rings 22 correspond one-to-one with the number and position of the fixing members 12. In the conveying direction of the fiber filaments 6, the filament adsorption rings 22 are located downstream of the fixing members 12, that is, the filament adsorption rings 22 are located in the extending direction of the fixing members 12. Figure 1 In the embodiment shown, the filament adsorption ring 22 is located above the fixing member 12, so that the fiber filament 6 enters the filament adsorption ring 22 along the axial direction of the winding tube 5 after being unwound from the winding tube 5, and passes through the middle of the filament adsorption ring 22. At the same time, the filaments on the fiber filament 6 are adsorbed by the filament adsorption ring 22.

[0036] The airflow traction component 3 uses airflow traction to unwind the fiber 6 from the winding drum 5 and pass it through the wool adsorption ring 22. The airflow traction component 3 can also use negative pressure adsorption to traction the fiber 6.

[0037] The collecting component 4 is used to collect the fiber filaments 6 that pass through the wool adsorption ring 22 and collect the unwound fiber filaments 6 in a unified manner.

[0038] In the fiber detection device of this application, the base assembly 1 is used to fix the winding cylinder 5, so that the fiber filaments 6 wound on the winding cylinder 5 form a smooth transition path, reducing the bending angle in the initial stage of unwinding and reducing frictional damage to the fiber filaments 6. At the same time, the number of fixing parts 12 can be flexibly set according to actual needs to adapt to different detection scenarios. In the support assembly 2, the lint adsorption ring 22 can ensure that the lint on the surface of the fiber filaments 6 is efficiently adsorbed when passing through in a predetermined direction, providing reliable conditions for lint detection. The airflow traction assembly 3 realizes the unwinding and conveying of the fiber filaments 6 through airflow traction, which can reduce contact damage to the fiber filaments 6 compared with mechanical traction and protect the original performance of the fiber filaments 6. The collection assembly 4 can collect the fiber filaments 6 passing through the lint adsorption ring 22 in a unified manner to prevent the fiber filaments 6 from scattering. The fiber detection device improves the accuracy, stability and efficiency of fiber detection.

[0039] In some embodiments, such as Figure 1 As shown, the support assembly 2 also includes a first guide 23, which is disposed on the frame 21. The first guide 23 can be made of metal or rigid plastic, and its material can be the same as that of the frame 21. The first guide 23 can be connected to the frame 21 by welding or snap-fit ​​connection. The first guide 23 is located between the filament adsorption ring 22 and the fixing member 12. After the fiber 6 is unwound from the winding cylinder 5, it first passes through the first guide 23. The first guide 23 guides the unwound direction of the fiber 6, causing the fiber 6 to be unwound along the axial direction of the winding cylinder 5. This unwound direction of the fiber 6 can amplify the minute defects in the fiber filament bundle, making the defects visible in ways such as splitting, winding, and breaking, facilitating the detection of the fiber filament 6. After passing through the first guide 23, the fiber 6 then passes through the filament adsorption ring 22, where the filaments on the fiber 6 are adsorbed.

[0040] In some embodiments, the fixing member 12, the first guide member 23, and the hair adsorption ring 22 correspond one-to-one, that is, as shown in the figure. Figure 1 In the example shown, a first guide 23 is correspondingly disposed above each fixing member 12, and a filament adsorption ring 22 is correspondingly disposed above each first guide 23. Therefore, when there are multiple fixing members 12, each fixing member 12 is correspondingly provided with a first guide 23 and a filament adsorption ring 22. The fibers 6 of the winding tube 5 fixed on the fixing member 12 are sequentially passed through the corresponding first guide 23 and filament adsorption ring 22. The support assembly 2 also includes a second guide 24, which is disposed on the frame 21, as shown in the example. Figure 1In the embodiment shown, the second guide 24 is located above the middle of the line connecting multiple filament adsorption rings 22, so that multiple filaments 6 can smoothly pass through the second guide 24 after passing through the corresponding filament adsorption rings 22. The second guide 24 facilitates the collection of filaments 6 from multiple winding cylinders 5 and also facilitates the collection of filaments 6 downstream.

[0041] In some embodiments, the first guide member 23 is a ring structure, and the inner diameter of the ring structure of the first guide member 23 corresponds to the diameter of the fiber filament 6, facilitating the passage of one fiber filament 6. The material of the first guide member 23 can be metal or rigid plastic. The second guide member 24 is also a ring structure, and the inner diameter of the ring structure of the second guide member 24 corresponds to the number of winding spools 5. When there is one winding spool 5, the second guide member 24 can allow one fiber filament 6 to pass through. When there are N winding spools 5, the second guide member 24 can allow N fiber filaments 6 to pass through. The material of the second guide member 24 can be metal or rigid plastic.

[0042] In some embodiments, the outer surfaces of the annular structures of the first guide member 23 and the second guide member 24 are all smooth curved surfaces. This arrangement of the first guide member 23 and the second guide member 24 ensures smooth movement of the fiber filament 6 while preventing damage to the surface of the fiber filament 6 from the first guide member 23 and the second guide member 24.

[0043] In some embodiments, the airflow traction assembly 3 includes a traction member 31, an air source unit 32, and a connecting pipe 33. The traction member 31 is mounted on the frame 21 via a connector, with its inlet facing the second guide member 24 to facilitate the suction of fiber filaments 6 passing through the second guide member 24. The outlet of the traction member 31 communicates with the collection assembly 4, allowing the fiber filaments 6 sucked from the second guide member 24 to be collected in the collection assembly 4. One end of the connecting pipe 33 communicates with the air source unit 32, and the other end communicates with the traction member 31. The connecting pipe 33 increases the distance between the traction member 31 and the air source unit 32, thereby increasing the ease of installation for both. In one example, the air source unit 32 can be a fan.

[0044] In some embodiments, such as Figure 2As shown, the fixing member 12 includes a fixing cylinder 121 and a clamping member 122. The axial direction of the fixing cylinder 121 is set at an angle to the base plate 11, and one end of the fixing cylinder 121 is fixed to the base plate 11. The fixing cylinder 121 can be fixed to the base plate 11 by welding or integral molding. One clamping member 122 or two or more clamping members 122 can be provided on one fixing cylinder 121. The clamping member 122 is provided to facilitate the fixing of the winding cylinder 5. Both ends of the clamping member 122 are fixed to the outer wall of the fixing cylinder 121. The fixing method can be welding or integral molding. The extension direction of the two ends of the clamping member 122 is parallel to the axial direction of the fixing cylinder 121. The middle part of the clamping member 122 is away from the fixing cylinder 121, and the middle part of the clamping member 122 is a protrusion. The winding spool 5 is nested outside the fixed cylinder 121 and the clamping member 122. The axial direction of the winding spool 5 is parallel to the axial direction of the fixed cylinder 121. The protruding part of the clamping member 122 abuts against the inner wall of the winding spool 5 to fix the winding spool 5. When installing the winding spool 5, the winding spool 5 is sleeved on the outside of the fixed cylinder 121 and the clamping member 122. The clamping member 122 deforms slightly, and at the same time, the clamping member 122 and the inner wall of the winding spool 5 abut against each other to fix it. When removing the winding spool 5, it can be pulled outward along the axial direction of the winding spool 5.

[0045] In some embodiments, the clamping member 122 is made of an elastic material, such as a rubber composite or an elastic alloy. The elastic properties of the clamping member 122 can deform accordingly with slight differences in the inner diameter of the winding spool 5, and automatically compensate for the gap through radial pressure to achieve stable fixation of winding spools 5 of various specifications.

[0046] In some embodiments, the filament adsorption ring 22 is made of nonwoven fabric. The nonwoven fabric configuration gives the filament adsorption ring 22 a high adsorption rate, ensuring that all filaments are captured, while the nonwoven fabric maintains flexible contact with the fiber filaments 6, avoiding damage to the fiber filaments 6. The filament adsorption ring 22 can also be made of other materials that have the ability to adsorb filaments without damaging the fiber filaments 6, such as meltblown fabric and degreased cotton fabric.

[0047] In some embodiments, the collection component 4 includes a delivery pipe 41 and a collection bag 42. One end of the delivery pipe 41 is connected to the airflow traction component 3, and the other end of the delivery pipe 41 is connected to the collection bag 42. The collection bag 42 and the delivery pipe 41 are detachably connected to facilitate cleaning of the fiber filaments 6 in the collection bag 42.

[0048] When using the fiber detection device for detection, the winding spool 5 with the fiber 6 wound around it is fixed on the fixing member 12. The lint adsorption ring 22 is removed and weighed. The weight of the lint adsorption ring 22 is M0. Then, the lint adsorption ring 22 is installed on the frame 21. The fiber 6 is passed through the lint adsorption ring 22, and the lint is pulled by the airflow traction component 3. The fiber 6 wound on the winding spool 5 passes through the lint adsorption ring 22 and enters the collection component 4. After the fiber 6 moves for a period of time, the fiber 6 unwinding is stopped. The lint adsorption ring 22 is removed and weighed. The weight of the lint adsorption ring 22 at this time is M1. It can be obtained that the mass of the lint on the surface of the fiber 6 during the unwinding process is m = M1 - M0. The lint condition of the fiber 6 is evaluated by the value of m. Meanwhile, during the test, the testers recorded the breakage of fiber filament 6 and set the fiber unwinding performance to K. For example, if there was no tangling or breakage of fiber filament 6 during the unwinding of 300m in 3 minutes, K=10; if tangling occurred once, the K value was reduced by 3; if breakage occurred once, the K value was reduced by 2. The smoothness of fiber filament 6 unwinding in the winding spool 5 can be evaluated by the K data. A K value greater than or equal to 8 indicates that the surface product has good unwinding performance and the unwinding is smooth and without abnormalities.

After 3 minutes, the process is stopped. The mass of the filament adsorption ring 22 after unwound is measured as M1 = 431.2 mg. Therefore, the amount of filaments on the fiber surface during the unwound process of the fiber shaft is m = M1 - M0 = 24 mg. The unwound process of the fiber shaft is smooth, with no broken or tangled fibers. Therefore, K = 10.

After 3 minutes, the process is stopped. The mass of the filament adsorption ring 22 after unwound is measured as M1 = 441.8 mg. Therefore, the amount of filaments on the fiber surface during the unwound process of the fiber shaft is m = M1 - M0 = 28.9 mg. The fiber shaft breaks once and gets entangled 0 times. Therefore, K = 8.

After 3 minutes, the process is stopped. The mass of the filament adsorption ring 22 after unwound is measured as M1 = 438.1 mg. Therefore, the amount of filaments on the fiber surface during the unwound process of the fiber shaft is m = M1 - M0 = 33.5 mg. The unwound process of the fiber shaft is smooth, with no broken or tangled fibers. Therefore, K = 10.

[0055] Comparative Example 1

After 3 minutes, the process is stopped. The mass of the filament adsorption ring 22 after unwound is measured as M1 = 488.1 mg. Therefore, the amount of filaments on the fiber surface during the unwound process is m = M1 - M0 = 73.6 mg. The fiber shaft breaks 3 times and gets entangled 0 times. Therefore, K = 4.

[0057] Comparative Example 2

[0059] Comparative Example 3

[0060] A fiber filament 6 with a sizing agent content of 1.97% wound on a winding cylinder 5 is designated as the fiber shaft. The fiber filament 6 is 300 meters long.

After 3 minutes, the process is stopped. The mass of the filament adsorption ring 22 after unwound is measured as M1 = 492.7 mg. Therefore, the amount of filaments on the fiber surface during the unwound process of the fiber shaft is m = M1 - M0 = 90.3 mg. The fiber shaft has 0 fiber breakages and 3 filament entanglements. Therefore, K = 1.

[0061] The data from Examples 1-3 and Comparative Examples 1-3 are summarized in the table below:

[0062]

[0063] As shown in the table above, the fiber filaments 6 produced using the same sizing agent at different concentrations exhibit significant differences in filament content and unwinding performance. In Examples 1, 2, and 3, the sizing agent content ranged from 1.03% to 1.21%, resulting in comparable filament counts with minimal differences. Example 2 showed one filament breakage, while the other examples showed no breakage or tangling. Unwinding performance was excellent, with normal unwinding at 100 m / min and a K value greater than 8, indicating no unwinding issues in practical production applications. Comparative Example 1, with its lower sizing agent content, exhibited poor abrasion resistance in fiber filaments 6, resulting in frequent breakage during unwinding and a K value of 4, thus failing the test. Comparative Examples 2 and 3, with higher sizing agent content, had more sizing agent on the surface of fiber filaments 6. Although fiber filaments 6 exhibited good abrasion resistance, the excess sizing agent formed adhesive particles between the fibers, causing them to adhere. During unwinding, these particles led to tangling of the fibers, affecting normal unwinding, and the K values ​​were 2 and 1, respectively, making them unqualified.
