Description

Technical Field

[0001] This utility model relates to the field of fiber detection technology, and in particular to a fiber measuring device. Background Technology

[0002] Carbon fiber linear density is an important parameter characterizing the physical properties of carbon fiber and a key control indicator in carbon fiber research and production. Carbon fiber linear density refers to the weight of a single bundle of fibers per unit length. Currently, the method for testing linear density typically involves sampling a fixed length from a carbon fiber spool and weighing it on an electronic balance to calculate the linear density of that section of carbon fiber. In daily production, due to the high strength and special properties of carbon fiber, the sampling process requires meticulous operation to avoid fiber damage or length changes, thus ensuring the accuracy of the measurement results. Secondly, for long-range linear density measurements—that is, continuous measurements (e.g., 50 or 100 times) of the same carbon fiber spool—traditional methods are not only time-consuming and labor-intensive but also require two people, undoubtedly increasing production costs and manpower consumption. More importantly, errors introduced by human operation are difficult to avoid, especially during long-term, high-frequency measurements. These errors may accumulate, leading to a decrease in the reliability of the measurement results. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] 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 present 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.

[0029] Carbon fiber is a new type of filamentous carbon material with a carbon content of over 90%, possessing excellent properties such as lightweight, high strength, high elastic modulus, resistance to high and low temperatures, and corrosion resistance. Carbon fiber is mainly used in aerospace, wind turbine blades, and sporting goods, and has broad market potential. The linear density of carbon fiber is an important parameter characterizing its physical properties and a key control indicator in its research and production.

[0030] Carbon fiber linear density refers to the weight of a single bundle of fibers per unit length. Currently, the method for testing linear density typically involves sampling a fixed length from a carbon fiber spool, weighing it on an electronic balance, and then calculating the linear density of that section of carbon fiber. In daily production, due to the high strength and special properties of carbon fiber, the sampling process requires meticulous operation to avoid fiber damage or length changes, thus ensuring the accuracy of the measurement results. Secondly, for long-range linear density measurements, i.e., measuring the linear density of the same carbon fiber spool multiple times (e.g., 50 or 100 times), traditional methods are not only time-consuming and labor-intensive but also require two people to work together, which undoubtedly increases production costs and manpower consumption. More importantly, errors caused by human operation are difficult to avoid, especially during long-term, high-frequency measurements. These errors may accumulate, leading to a decrease in the reliability of the measurement results.

[0031] The following is combined Figures 1-2 The embodiments of this utility model are further described below.

[0032] To address the aforementioned technical problems, this invention provides a fiber measuring device. The fiber passes through a first groove on the operating table and is simultaneously cut by cutting sections at both the first and second cutting positions. These cutting sections can continuously cut multiple sample segments from the same carbon fiber shaft, ensuring consistent sample lengths each time and eliminating deviations from manual length measurements. The cut fiber falls directly into a weighing device, and the linear density of that segment is calculated based on its length and weight. This allows for the acquisition of linear densities from different samples, resulting in more stable and accurate linear density data. This solution addresses the issues of high labor costs, long testing times, and large errors, improving testing efficiency and accuracy.

[0033] An exemplary embodiment of this disclosure provides a fiber measuring device, such as... Figure 1As shown, the device includes an operating table 1, a cutting section 2, and a weighing section. The operating table 1 can be made of metal, such as iron or steel. The upper surface of the operating table 1 has a first groove 110 for the fiber 4 to be measured to pass through. The first groove 110 provides a clear positioning and guiding path for the fiber 4, ensuring it remains straight during measurement and avoiding measurement errors caused by bending or deviation of the fiber 4. The operating table 1 has a first cutting position and a second cutting position, each with a cutting section 2 for cutting the fiber 4 within the first groove 110. A weighing device 3 is located on the operating table 1, between the first and second cutting positions, at the bottom of the first groove 110, to receive the cut fiber 4 and weigh it. Fiber 4 passes through the first groove 110 on the operating table 1 and is simultaneously cut by the cutting parts 2 at the first and second cutting positions. The cutting parts 2 can continuously cut multiple sample segments from the fiber 4 on the same carbon filament shaft, ensuring that the sample length is consistent each time and eliminating the deviation when measuring length manually. The cut fiber 4 falls directly into the weighing device 3. The linear density of the fiber 4 segment is calculated based on its length and weight, thereby obtaining the linear density of different samples. This results in more stable and accurate linear density data, solving the problems of high labor costs, long testing time, and large errors, and improving testing efficiency and accuracy.

[0034] In some embodiments of this utility model, reference is made to Figure 1 A second groove 120 is provided at the first cutting position of the operating table 1, and a third groove 130 is provided at the second cutting position. Both the second groove 120 and the third groove 130 are connected to the first groove 110. A cutting part 2 is provided within both the second groove 120 and the third groove 130, and the cutting direction of the cutting part 2 is parallel to the bottom of the grooves of the second groove 120 and the third groove 130. For example, referring to… Figure 1 The length direction of the second groove 120 (i.e. Figure 1 The y-axis direction and the length direction of the first groove 110 (i.e., the direction of the y-axis) are parallel to each other. Figure 1 The second groove 120 is set vertically in the X-axis direction and in the length direction of the X-axis direction. Figure 1 The y-axis direction and the length direction of the third groove 130 (i.e., the direction of the y-axis) ... Figure 1The second groove 120, the third groove 130 and the first groove 110 are arranged parallel to each other in the y-axis direction to form a U-shaped structure. The cutting part 2 is installed in the second groove 120 and the third groove 130, which forms a physical isolation from other parts of the operating table 1. This reduces the risk of the cutting part 2 accidentally coming into contact with the operator or other objects during the cutting process, thereby reducing the possibility of accidents and ensuring safety during the cutting process.

[0035] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 The cutting unit 2 includes a drive unit 201, a telescopic rod 202, and a cutter head 203. The output end of the drive unit 201 is connected to the first end of the telescopic rod 202, and the second end of the telescopic rod 202 is detachably connected to the cutter head 203. The cutter head 203 can be replaced periodically to maintain its sharpness and ensure the cutting effect. The extension direction of the telescopic rod 202 is perpendicular to the running direction of the fiber 4 to be measured. The cutter head 203 acts on the first sidewall of the first groove 110, and the first sidewall is perpendicular to the extension direction of the telescopic rod 202. The extension direction of the telescopic rod 202 is perpendicular to the running direction of the fiber 4 to be measured, ensuring the accuracy of the cutting. This allows the cutting unit 2 to perform straight cutting along a predetermined path, reducing deviations during the cutting process, improving cutting accuracy, and thus obtaining a more accurate linear density result for the fiber 4.

[0036] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 The cutting unit 2 also includes a connecting rod 204 and a pressure rod 205. The middle part of the connecting rod 204 is connected to the output end of the drive unit 201, one end of the connecting rod 204 is connected to one end of the pressure rod 205, and the other end of the connecting rod 204 is connected to one end of the telescopic rod 202, which is an electric telescopic rod 202. For example, the drive unit 201 includes a linear motor. When the fiber 4 needs to be cut, the drive unit 201 drives the connecting rod 204 to move, and the connecting rod 204 drives the pressure rod 205 to move, so that the end of the pressure rod 205 presses the fiber 4 firmly against the first sidewall of the first groove 110. Then, the electric telescopic rod 202 starts working. The electric telescopic rod 202 is a device that can automatically extend or shorten as needed. The electric telescopic rod 202 drives the cutter head 203 to cut the fiber 4. By using the pressure rod 205 to stably press the fiber 4 against the first sidewall during the cutting process, inaccurate cutting caused by the movement or shaking of the fiber 4 is prevented. Meanwhile, the telescopic function of the electric telescopic rod 202 ensures that the cutter head 203 can cut at a constant speed and force, further improving the stability and quality of the cutting.

[0037] In some embodiments of this utility model, reference is made to Figure 1A buffer layer 111 is provided on the first sidewall, wherein the buffer layer 111 includes, but is not limited to, materials such as rubber and silicone. Thus, by providing the buffer layer 111 on the first sidewall, the cutting head 203 acts on the buffer layer 111, which effectively absorbs the impact force and vibration generated by the cutting head 203 during the cutting process, preventing the first sidewall from wearing or cracking due to long-term direct impact. It also reduces the wear rate of the cutting head 203 and extends its service life.

[0038] In some embodiments of this utility model, reference is made to Figure 1 A first switch 140 is installed on the operating table 1, and the first switch 140 is electrically connected to the drive unit 201. The first switch 140 drives the drive unit 201. When both ends of the fiber 4 are outside the first groove 110, the operator presses the first switch 140, and the drive unit 201 immediately moves the connecting rod 204. This greatly improves operational efficiency, ensures the accuracy and consistency of fiber 4 cutting, avoids quality problems caused by delays or errors, reduces manual intervention, and simplifies the operation process.

[0039] In some embodiments of this utility model, reference is made to Figure 1 The fiber measuring device also includes a weight display 170, which is electrically connected to the weighing device 3 and is mounted on the upper surface of the operating table 1. After the weight display 170 stabilizes, the operator can directly read the weight data of the fiber 4 through the weight display 170 on the operating table 1, greatly improving the convenience and efficiency of operation.

[0040] In some embodiments of this utility model, reference is made to Figure 1 The control panel 1 is also equipped with a recorder 180, which is used to record the measurement data of the weighing device 3 and to export the measurement data to external devices. The recorder 180 can store the measurement data for a long time, allowing the operator to view and analyze past measurement results at any time. The recorder 180 can also export the measurement data to external devices, which is convenient for the statistical analysis and viewing of the linear density of the fiber 4.

[0041] In some embodiments of this utility model, reference is made to Figure 1 The control panel 1 is equipped with a second switch 150, which is electrically connected to the weighing device 3. The second switch 150 is used to initialize the weighing device 3. After the operator presses the second switch 150, the weighing device 3 can be initialized, which clears the previous measurement data, calibrates the sensor, and ensures the accuracy of the next measurement.

[0042] In some embodiments of this utility model, reference is made to Figure 1The fiber measuring device also includes adjustable supports 190 located at the four corners of the lower surface of the operating table 1. These adjustable supports 190 are used to adjust the flatness of the operating table 1. A third switch 160 is also provided on the operating table 1, electrically connected to each of the adjustable supports 190. Before measurement, the operator presses the third switch 160, allowing the adjustable supports 190 to be adjusted in height to ensure the flatness of the operating table 1. This eliminates measurement errors caused by unevenness, provides stable support for the operating table 1, effectively prevents measurement errors or equipment damage caused by table shaking or tilting, and improves measurement accuracy.
