[0023] This application provides a fiber inspection device that integrates inspection components into the production line. These components, along with sensors and fiber-insertable inspection elements, detect the pressure exerted by the fibers on the inspection elements during fiber movement, enabling real-time detection of fiber interlacing degree and immediate acquisition of interlacing degree data. Simultaneously, a flattening component is installed between the inspection components and the winding assembly. This flattening component flattens the fibers based on the pressure value detected by the sensors, thereby altering the fiber interlacing degree. Specifically, it loosens the fibers when the interlacing degree is too high and reduces disturbance when it is too low, thus achieving dynamic adjustment of the flattening force based on real-time interlacing degree conditions. This design avoids the generation of batches of defective fibers due to offline inspection delays, reducing raw material waste and production capacity loss. By detecting interlacing degree in real-time on the fiber production line and adjusting the fiber interlacing degree accordingly, inspection efficiency and fiber pass rate are improved.

[0030] 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.
[0031] The degree of interlacing in fibers refers to the extent and connection between fiber bundles. The degree of interlacing affects the properties of the finished product made from the fiber; therefore, it is necessary to detect the degree of interlacing during fiber production. Current technologies rely on offline sampling and testing, which suffers from poor timeliness and difficulty in responding to fluctuations in the degree of interlacing in real time.
[0032] Based on this, such as Figure 1 As shown in the figure, this application provides a fiber detection device for real-time detection of fiber 5 on the fiber 5 production line to obtain real-time interlacing degree data. At the same time, it can also adjust the interlacing degree of fiber 5 in real time according to the interlacing degree, thereby improving detection efficiency and fiber 5 pass rate.
[0033] The fiber inspection device includes a guide roller 1, a winding component 2, an inspection assembly 3, and a flattening assembly 4. On the fiber 5 production line, the guide roller 1 guides the direction of travel of the fiber 5, preventing the fiber 5 from deviating, tangling, or loosening. For example, the side of the guide roller 1 that contacts the fiber 5 is a smooth curved surface to avoid damage to the fiber 5. The position of the guide roller 1 can be varied to adjust the tension of the fiber 5, for example, by using a drive cylinder to move the guide roller 1.
[0034] The winding element 2 is positioned downstream of the guide roller 1 along the fiber 5's travel direction. It winds the fiber 5 to achieve fiber winding, facilitating subsequent storage or processing. Exemplarily, the winding element 2 can be roller-shaped or sleeve-shaped, without specific limitation.
[0035] In such Figure 1 In one example shown, the detection component 3 is located between the guide roller 1 and the winding component 2. In other examples, the detection component 3 can also be located at any step of the fiber 5 production line to detect the interlacing degree of the fibers 5 at different stages. The detection component 3 can be fixedly mounted on the frame of the production line for routine detection of the interlacing degree of the fibers 5 passing through that location. Alternatively, it can be mounted on another movable frame and moved to the location to be detected when interlacing degree needs to be checked.
[0036] The detection component 3 includes a sensor 31 and at least one detection element 32. The detection element 32 is inserted into the fiber 5. The sensor 31 detects the pressure exerted by the fiber 5 on the detection element 32 during its movement. The sensor 31 can be a pressure sensor, which converts the pressure on the fiber 5 into a digital signal, and the real-time interlocking degree can be directly calculated. For example, the higher the pressure value, the higher the interlocking degree; conversely, the lower the pressure value, the lower the interlocking degree. In one example, the detection element 32 is inserted into the fiber 5 throughout its movement, performing real-time detection of the fiber 5. In another example, depending on the specific situation, the detection element 32 can be inserted into the fiber 5 only when detection is needed, and removed from the fiber 5 when detection is not needed, thus saving resources.
[0037] The flattening component 4 is disposed between the detection component 3 and the winding component 2. The flattening component 4 is used to flatten the fiber 5 according to the pressure value detected by the sensor 31, so as to change the interlacing degree of the fiber 5. That is, when the pressure value detected by the sensor 31 is large, it indicates that the interlacing degree of the fiber 5 is high. At this time, the flattening component 4 flattens the fiber 5 to reduce the interlacing degree. When the pressure value detected by the sensor 31 is small, it indicates that the interlacing degree of the fiber 5 is low, that is, the fiber 5 is loose. At this time, the flattening of the fiber 5 is reduced to reduce the disturbance to the fiber 5 and avoid the fiber 5 becoming too loose.
[0038] For example, when flattening the fiber 5 in real time according to the pressure detected by the sensor 31, a preset range value can be set. When the degree of interlacing detected by the sensor 31 is within the preset range value, the flattening component 4 flattens the fiber 5, and the flattening force can be adjusted according to the real-time degree of interlacing.
[0039] In one example, the flattening component 4 can flatten the fiber 5 by means of vibration, shaking, or other methods, without any specific limitation.
[0040] For example, in this embodiment, the flattening component 4 is located downstream of the detection component 3 along the traveling direction of the fiber 5, and adjusts the interlacing degree of the fiber 5 in real time based on the detection results. Of course, the flattening component 4 can also be located upstream of the detection component 3, first flattening the fiber 5, and then detecting whether the interlacing degree is qualified by the detection component 3.
[0041] In this embodiment, by integrating the detection component 3 into the production line, along with the sensor 31 and the fiber-insertable detection component 32, the sensor 31 detects the pressure of the fiber on the detection component 32 during its movement, enabling real-time detection of fiber interlacing degree and instant acquisition of interlacing degree data. Simultaneously, a flattening component 4 is placed between the detection component 3 and the winding component 2. The flattening component 4 flattens the fiber based on the pressure value detected by the sensor 31, thereby changing the fiber interlacing degree. Specifically, when the interlacing degree is too high, the fiber is loosened; when the interlacing degree is too low, disturbance is reduced, thus achieving dynamic adjustment of the flattening force according to the real-time interlacing degree. This design avoids the generation of batches of defective fibers due to offline detection lag, reducing raw material waste and production capacity loss. By detecting the interlacing degree in real time on the fiber production line and adjusting the fiber interlacing degree in real time according to the interlacing degree, detection efficiency and fiber qualification rate are improved.
[0042] In some embodiments, such as Figure 1-2 As shown, the detection assembly 3 also includes a fixing member 33, which is used to fix the sensing element 31 and the detection element 32. Exemplarily, the fixing member 33 can be a fixing frame structure, a shaft structure, or other configuration forms, which are not specifically limited here. The fixing member 33 is used to stably assemble the sensing element 31 and the detection element 32. When multiple detection elements 32 are provided, all multiple detection elements 32 are set on the fixing member 33. Multiple detection elements 32 can be moved simultaneously by moving the position of the fixing member 33, improving efficiency.
[0043] In some embodiments, such as Figure 1-2As shown, the fixing member 33 is a shaft structure, and the axial direction of the shaft structure is parallel to the axial direction of the guide roller 1. This allows the extension direction of the shaft structure to be adapted to the fiber spreading direction, facilitating the insertion of the detection member 32 into the fiber and improving the convenience of fiber detection. In some embodiments, such as... Figure 2 As shown, multiple detection elements 32 are spaced apart along the axial direction of the shaft structure, with equal spacing between adjacent detection elements 32. This design improves the uniformity of fiber detection, thereby enhancing the accuracy of fiber interlacing degree detection results. The spacing between adjacent detection elements 32 matches the width of the fiber 5, preventing missed detections at fiber edge areas due to excessive spacing or redundant detection data due to insufficient spacing. In one example, multiple threaded holes are evenly distributed on the shaft structure. The detection elements 32 are threadedly installed in these holes, allowing the operator to adjust the distance between adjacent detection elements 32 by changing their installation positions in different threaded holes, based on the fiber 5 width.
[0044] In some embodiments, the length of the shaft structure in the axial direction is equal to the width of the fiber 5 in the axial direction of the guide roller 1. This allows the length of the shaft structure to be adapted to the width of the fiber spreading, so as to keep in line with the width of the fiber spreading of the entire production line, thereby further improving the convenience of fiber inspection.
[0045] In some embodiments, such as Figure 1 As shown, the detection element 32 has a needle-like structure, and the insertion end of the needle-like structure is a smooth hemispherical or conical shape. This design not only makes the detection element 32 structurally simple and easy to manufacture and process, but also facilitates insertion into the fiber, thereby further improving the convenience of fiber interlacing degree detection. Furthermore, by setting the insertion end of the needle-like structure to a smooth hemispherical or conical shape, wear caused by friction with the fiber 5 can be reduced, thus improving the quality of the fiber product. For example, the surface of the needle-like structure is a smooth curved surface, which is less prone to the adhesion of fiber 5 lint, reducing wear caused by friction with the fiber 5 and further improving the quality of the fiber product.
[0046] In some embodiments, such as Figure 1 As shown, the flattening assembly 4 includes a flattening roller 41 and a drive unit 42. The flattening roller 41 is located between the detection assembly 3 and the winding member 2. The flattening roller 41 is used to directly contact the fiber 5 and flatten the fiber 5. The side of the flattening roller 41 that contacts the fiber 5 is a smooth curved surface, which can avoid damaging the fiber 5 and reduce the frictional resistance with the fiber 5, thus preventing the generation of fuzz during vibration.
[0047] The drive unit 42 drives the flattening roller 41 to vibrate, thereby flattening the fiber 5. In scenarios with high interlacing degree, the interlacing degree of the fiber 5 can be quickly reduced by increasing the vibration frequency. In scenarios with low interlacing degree, the vibration frequency can be reduced or the drive unit 42 can be turned off to avoid excessive disturbance to the fiber 5. Exemplarily, the drive unit can be, for example, a vibration motor or an electromagnetic vibrator.
[0048] The above-described configuration simplifies the structure of the flattening component 4, making it easy to produce and process, while also improving the convenience of fiber flattening.
[0049] In some embodiments, the drive unit 42 is a vibration motor, and the output shaft of the vibration motor is connected to the flattening roller 41. The vibration motor can improve the vibration transmission efficiency and ensure a uniform and stable flattening effect.
[0050] In some embodiments, the fiber detection device further includes a control unit, which is communicatively connected to the sensor 31 and the drive unit 42. The control unit is configured to control the frequency of vibration of the flattening roller 41 driven by the drive unit 42 based on the pressure value detected by the sensor 31. The control unit enables precise adjustment of the interlacing degree, ensuring the consistency of fiber 5 quality. It also reduces manual intervention, operational errors, and costs.
[0051] In some embodiments, the outer peripheral surface of the guide roller 1 is provided with an elastic wear-resistant layer. This elastic wear-resistant layer can be made of silicone or rubber. This protects the fibers 5, reducing production losses, and also improves guiding stability and ensures detection accuracy.
