[0038] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0039] In fiber manufacturing companies, fiber fineness needs to be measured. However, traditional fineness measurement methods often have limitations. Current technology typically involves measurement after fiber production is complete, often using samples from only a small portion of the fiber at the end of the production process. If material instability during fiber production leads to fineness instability, testing only this small portion is insufficient to reflect the true uniformity of the fiber and cannot comprehensively reflect the fineness changes throughout the entire production process.
[0040] To address the aforementioned technical problems, this invention provides an apparatus and method for detecting the uniformity of wound fibers. In the apparatus, a flexible connection between the support rod and the power unit allows for smooth rotation, ensuring the power unit can drive the support rod to rotate smoothly around its axis, thus improving the apparatus's flexibility and adaptability. A weighing unit acquires real-time data on the weight changes of the fiber roll, providing reliable data support for uniformity assessment. Simultaneously, the method for detecting the uniformity of wound fibers automatically adjusts the rotational speed of the power unit based on preset parameters and real-time data, making the fiber winding process more intelligent and automated, reducing manual intervention and improving production efficiency. Then, by combining the first lever arm at the first force application point, the second lever arm at the second force application point, and the linear velocity of the fiber roll, the uniformity of the fiber roll is accurately calculated. Based on preset parameter values at different times, the uniformity of the fiber roll is dynamically evaluated, enabling timely detection and correction of problems during the winding process, ensuring stable product quality.
[0041] An exemplary embodiment of the present invention provides a device for detecting the uniformity of wound fibers. The device includes a support rod 4, a power unit 1, and a weighing unit 2. The power unit 1 can be a servo motor or other motor capable of rotation, and the weighing unit 2 can be an electronic scale, sensor, or other weighing tool. The first end of the support rod 4 supports the fiber roll 3, forming a first point of force application on the support rod 4. It should be noted that, as... Figure 1 As shown, the first point of force application is the center of gravity of the fiber roll 3 after it is fitted onto the support rod 4. The output end of the power unit 1 is flexibly connected to the second end of the support rod 4 to form a lever fulcrum. The power unit 1 is used to drive the support rod 4 to rotate, thereby causing the fiber roll 3 to wind. It should be noted that the connection between the output end of the power unit 1 and the support rod 4 is flexible. This is necessary to ensure that the output end of the power unit 1 can drive the rotation of the support rod 4, while avoiding unnecessary support force exerted by the power unit 1 on the support rod 4. This is because any support force could interfere with the accurate measurement of the weighing unit 2, thereby affecting the accuracy and reliability of the uniformity of the fiber roll 3. The weighing unit 2 is located below the support rod 4, and the weighing surface of the weighing unit 2 supports the support rod 4 at a preset position to form the second point of force application on the support rod 4. It should be noted that when the power unit 1 drives the fiber roll 3 to run, the linear speed of the fiber roll 3 is relatively fast. If direct weighing is used, the fiber filaments need to be cut in actual production, damaging the raw materials and increasing production costs. In this way, the flexible connection between the support rod 4 and the power unit 1 enables flexible rotation, ensuring that the power unit 1 can drive the support rod 4 to rotate smoothly around its axis, thus improving the flexibility and adaptability of the device. The weight change of the fiber roll 3 is obtained in real time through the weighing unit 2, providing reliable data support for uniformity judgment. The real-time uniformity of the fiber roll 3 is obtained based on preset parameters and real-time data, making the fiber roll 3 winding process more intelligent and automated, reducing manual intervention and improving production efficiency.
[0042] In some embodiments of the present invention, reference is made to Figure 1 The output end of the power unit 1 is connected to the second end of the support rod 4 via a double cross-shaft universal joint, enabling the output end of the power unit 1 to drive the support rod 4 to rotate around its axis, and the support rod 4 to rotate around the lever fulcrum. The double cross-shaft universal joint allows the support rod 4 to rotate flexibly within a certain angle range, allowing the output end of the power unit 1 to drive the support rod 4 to rotate around its axis in multiple angles and directions. When the fiber roll 3 is fitted onto the support rod 4, the power unit 1 does not exert any supporting force on the support rod 4, and the weighing unit 2 is not interfered with by the supporting force when measuring the weight of the fiber roll 3, thereby improving the accuracy of the calculation results.
[0043] In some embodiments of the present invention, reference is made to Figure 1The device for detecting the uniformity of wound fibers also includes a numerical control unit 5; the numerical control unit 5 is electrically connected to the weighing unit 2, and the numerical control unit 5 is used to determine the uniformity result of the fiber roll 3 based on the weighing value of the weighing unit 2, the first lever arm L2 of the first force application point, the second lever arm L1 of the second force application point, and the linear velocity of the fiber roll 3. For example, refer to... Figure 1 Using the connection point between the output end of the power unit 1 and the support rod 4 as the fulcrum, and the center of gravity of the fiber roll 3, which is sleeved behind the support rod 4, as the first point of application of force, the fiber roll 3 exerts a downward pressure F2 on the support rod 4. The distance from the first point of application of force to the fulcrum is the first lever arm L2. Placing the support rod 4 at its center of gravity behind the weighing unit 2 is the second point of application of force. At this point, the weighing unit 2 exerts an upward supporting force F1 on the support rod 4. The distance from the second point of application of force to the fulcrum is the second lever arm L1. As time increases, the fiber roll 3 begins to wind, and the weight begins to increase. During this process, the value displayed on the weighing unit 2 continuously increases. According to the lever principle:
[0044] L1*F1=L2*F2
[0045] L1*M1*g=L2*M2*g
[0046] L1*M1=L2*M2
[0047] Where L1 is the second lever arm, L2 is the first lever arm, F1 is the supporting force at the second force application point, F2 is the pressure at the first force application point, M1 is the weight measured by the weighing part 2, M2 is the total weight of the support rod 4 and the fiber roll 3, and g is the gravitational acceleration.
[0048] Linear density formula:
[0049] M / L = M / V*t
[0050] Where M is the weight, L is the length, V is the linear velocity of fiber roll 3, and t is the winding time of fiber roll 3.
[0051] Uniformity calculation formula:
[0052]
[0053] In this formula, the variables are the weight M1 weighed by the weighing unit 2 and the time t. Since the linear velocity v is constant, and assuming the fiber is uniform, the weight M1 weighed by the weighing unit 2 and the time t are theoretically proportional. Therefore, the value of α should be fixed. Thus, by combining the first lever arm of the first force application point, the second lever arm of the second force application point, and the linear velocity of the fiber roll 3, the uniformity of the entire fiber roll 3 can be accurately calculated. Dynamically evaluating the uniformity of the fiber roll 3 allows for timely detection and correction of problems during the winding process, ensuring stable product quality.
[0054] In some embodiments of the present invention, reference is made to Figure 1 Fiber roll 3 is used to connect to the fiber production equipment. The CNC unit 5 is also electrically connected to the power unit 1. The CNC unit 5 controls the rotational speed of the power unit 1 to match the output speed of the fiber production equipment. By precisely controlling the rotational speed of the power unit 1, the CNC unit 5 ensures that the fiber production equipment outputs material at a constant speed. Thus, by monitoring and adjusting the rotational speed of the power unit 1 in real time, the CNC unit 5 ensures the stability of the production process, helps reduce fluctuations and uncertainties in production, and improves overall production efficiency.
[0055] Another embodiment of the present invention provides a method for detecting the uniformity of wound fibers, applied to the apparatus described in any of the above embodiments, with reference to... Figure 2 This includes the following steps:
[0056] Step S1. Control the output end of the power unit to rotate at a preset speed to drive the support rod and the fiber roll on the support rod to rotate.
[0057] The linear velocity of the fiber roll 3 is denoted as V, which is adjusted by the CNC unit 5 at the output end of the power unit 1.
[0058] Step S2. Obtain the real-time weighing value of the weighing unit.
[0059] Before the motor starts, the numerical control unit 5 resets the weighing module value to zero. As time increases, the fiber roll 3 begins to wind, and the weight of the weighing unit 2 begins to increase. During this process, the value displayed by the weighing unit 2 continuously increases, denoted as M1.
[0060] Step S3. Determine the uniformity result of the fiber roll based on the real-time weighing value, the first lever arm of the first force application point, the second lever arm of the second force application point, and the linear velocity of the fiber roll.
[0061] The rotational speed of the power unit 1 is automatically adjusted according to preset parameters and real-time data, making the fiber roll 3 winding process more intelligent and automated, reducing manual intervention and improving production efficiency. Then, by combining the first lever arm of the first force application point, the second lever arm of the second force application point and the linear velocity of the fiber roll 3, the uniformity of the fiber roll 3 is accurately calculated. Based on the preset parameter values at different times, the uniformity of the fiber roll 3 is dynamically evaluated, which can promptly detect and correct problems in the winding process and ensure the stability of product quality.
[0062] In some embodiments of the present invention, reference is made to Figure 1Based on the real-time weighing value, the first lever arm L2 at the first force application point, the second lever arm L1 at the second force application point, and the linear velocity V of the fiber roll 3, the uniformity result of the fiber roll 3 is determined. This includes: determining the parameter values of preset parameters at different times based on the real-time weighing value M, the first lever arm L2 at the first force application point, the second lever arm L2 at the second force application point, and the linear velocity V of the fiber roll 3. The preset parameters are used to characterize the linear density. Based on the parameter values of the preset parameters at different times, the uniformity result of the fiber roll 3 is determined. In this way, by using parameters such as real-time weighing value and linear velocity, the linear density information of the fiber roll 3 at different times can be obtained in real time, thereby realizing real-time monitoring of uniformity, comprehensively understanding the uniformity of the fiber roll 3 throughout the entire production process, increasing the reliability of the evaluation results, and reducing the errors that may be caused by a single parameter.
[0063] In some embodiments of the present invention, reference is made to Figure 1 Based on the real-time weighing value M, the first lever arm L2 at the first force application point, the second lever arm L1 at the second force application point, and the linear velocity V of the fiber roll 3, the parameter values of the preset parameters at different times are determined, including:
[0064] The parameter value α of the preset parameter is calculated using the following formula:
[0065]
[0066] Where M is the real-time weighing value, L1 is the second lever arm, L2 is the first lever arm, V is the linear velocity of the fiber roll 3 winding, and t is the winding time of the fiber roll 3.
[0067] For example, refer to Figure 1 Using the connection point between the output end of the power unit 1 and the support rod 4 as the fulcrum, and the center of gravity of the fiber roll 3, which is sleeved behind the support rod 4, as the first point of application of force, the fiber roll 3 exerts a downward pressure F2 on the support rod 4. The distance from the first point of application of force to the fulcrum is the first lever arm L2. Placing the support rod 4 at its center of gravity behind the weighing unit 2 is the second point of application of force. At this point, the weighing unit 2 exerts an upward supporting force F1 on the support rod 4. The distance from the second point of application of force to the fulcrum is the second lever arm L1. As time increases, the fiber roll 3 begins to wind, and the weight begins to increase. During this process, the value displayed on the weighing unit 2 continuously increases. According to the lever principle:
[0068] L1*F1=L2*F2
[0069] L1*M1*g=L2*M2*g
[0070] L1*M1=L2*M2
[0071] Where L1 is the second lever arm, L2 is the first lever arm, F1 is the supporting force at the second force application point, F2 is the pressure at the first force application point, M1 is the weight measured by the weighing part 2, M2 is the total weight of the support rod 4 and the fiber roll 3, and g is the gravitational acceleration.
[0072] Linear density formula:
[0073] M / L = M / V*t
[0074] Where M is the weight, L is the length, V is the linear velocity of fiber roll 3, and t is the winding time of fiber roll 3.
[0075] Obtain the parameter value α of the preset parameter:
[0076]
[0077] In this formula, the variables are the weight M1 weighed by the weighing unit 2 and the time t. Since the linear velocity v is constant, and assuming the fiber is uniform, the weight M1 weighed by the weighing unit 2 and the time t are theoretically proportional. Therefore, the value of α should be fixed. Thus, by combining the first lever arm of the first force application point, the second lever arm of the second force application point, and the linear velocity of the fiber roll 3, the uniformity of the entire fiber roll 3 can be accurately calculated. Dynamically evaluating the uniformity of the fiber roll 3 allows for timely detection and correction of problems during the winding process, ensuring stable product quality.
[0078] In some embodiments of the present invention, reference is made to Figure 1 The process of determining the uniformity of fiber roll 3 based on preset parameter values at different times includes: obtaining the maximum and minimum values of the preset parameters at different times, and determining the uniformity result based on the maximum and minimum values. In this way, by obtaining preset parameter values at different times, a comprehensive understanding of the changes in fiber roll 3 during the production process can be achieved. The maximum and minimum values, as extreme values, reflect the limits of fiber roll 3 in terms of uniformity, thus allowing for a more accurate assessment of its overall uniformity. By observing the changing trends of the maximum and minimum values, the overall uniformity of fiber roll 3 can be analyzed, and timely adjustments to production parameters can further improve the uniformity of fiber roll 3, thereby enhancing product quality and production efficiency.
[0079] In some embodiments of the present invention, reference is made to Figure 1Based on the maximum and minimum values, the uniformity result is determined, including using the ratio or difference between the maximum and minimum values as the uniformity result. According to the calculation formula for parameter α, the variables are the weight M1 weighed by weighing unit 2 and time t. Since the linear velocity v is constant, theoretically, the weight M1 weighed by weighing unit 2 and time t are proportional when the fibers are uniform. Therefore, the value of α should be fixed. However, in practice, fluctuations may occur. The smaller the difference between the maximum and minimum values, or the closer the ratio between the maximum and minimum values is to 1, the more uniform the fiber roll 3 is; conversely, the larger the difference, the less uniform it is. Thus, by calculating the ratio or difference between the maximum and minimum values, an intuitive numerical value can be obtained. This value clearly reflects the dispersion or uniformity level of the dataset. When the ratio or difference exceeds the preset range, it indicates that the uniformity of fiber roll 3 has decreased, allowing for timely adjustments.
[0080] In some embodiments of the present invention, the method further includes: sending a signal to the fiber production equipment that the uniformity result does not meet the requirements. Thus, by sending a signal to the production equipment, the problem of unmet uniformity requirements can be detected immediately, thereby preventing the continued production of defective fiber rolls 3 and reducing the generation of defective products. Based on the signal feedback, production personnel can adjust the parameters of the production equipment in a timely manner to improve the uniformity of the product. By promptly detecting and resolving problems, the generation of a large number of unqualified fiber rolls 3 can be avoided, thereby reducing the waste of raw materials and energy. Real-time monitoring of the uniformity during the production process ensures the stability and controllability of the production process.
