[0019] 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 feature vectors in the embodiments of this application can be arbitrarily combined with each other.

[0020] When fiber bundles enter the oxidation and carbonization furnaces, the tension of the fiber bundles changes due to variations in the furnace temperature field. Therefore, it is necessary to monitor the tension of the fiber bundles to improve fiber performance. Currently, fiber bundle tension measurement requires manual, timed measurements, which cannot provide real-time information on tension changes, thus affecting product quality.

[0021] To address the aforementioned issues, this application provides a tension detection device. The tension detection device includes: a slide rail assembly, a guide roller, a detection bracket, a probe, and a tension conversion device. The slide rail assembly includes two opposing slide rails. The guide roller guides the fiber filaments through the slide rails, and the fiber filaments drive the guide roller to move along the sliding direction of the slide rails. The detection bracket and probe move synchronously with the guide roller. The tension conversion device detects the movement distance of the probe and converts this distance into the tension of the fiber filaments. By automatically and in real-time detecting the tension of the fiber filaments, the detection accuracy is improved, thereby improving production quality and reducing the cost of manual inspection.

[0022] One embodiment of this application provides a tension detection device, such as... Figure 1 As shown, the tension detection device 1 includes a slide rail assembly, a guide roller 12, a detection bracket 13, a detection element 14, and a tension conversion device 15. The slide rail assembly includes two slide rails 11 arranged opposite each other, with the sliding directions of the two slide rails 11 being parallel. The sliding direction of the slide rails 11 is vertical, as shown below. Figure 1 The Z direction in the equation.

[0023] like Figure 1As shown, the guide roller 12 is slidably connected to two slide rails 11 at its two ends in the axial direction. The guide roller 12 can move along the slide rails 11 and is used to guide the passage of the fiber filament. The fiber filament can drive the guide roller 12 to move along the sliding direction of the slide rails 11. For example, the axial direction of the guide roller 12 is parallel to the horizontal direction. The fiber filament passes through the bottom of the guide roller 12 and abuts against the bottom of the guide roller 12, and the fiber filament is pulled forward. When the tension of the fiber filament increases, the fiber filament is tightened and lifts the guide roller 12 to move upward along the sliding direction of the slide rails 11. When the tension of the fiber filament decreases, the guide roller 12 presses down on the fiber filament under its own gravity and drives the fiber filament to move downward along the sliding direction of the slide rails 11. The fiber filament can be carbon fiber filament.

[0024] like Figure 1 As shown, the detection bracket 13 is slidably connected to the slide rail 11 and can move synchronously with the guide rail. Exemplarily, the detection bracket 13 is disposed at the bottom of the guide roller 12, and a passage space exists between the detection bracket 13 and the guide roller 12, through which the fiber filament passes. A probe 14 is disposed on the detection bracket 13 and moves synchronously with it. Exemplarily, one, two, or more probes 14 may be provided. A tension conversion device 15 is used to detect the moving distance of the probe 14 and convert the moving distance into the tension of the fiber filament. Exemplarily, when the probe 14 moves upward relative to its initial position, the moving distance is a positive value; when the probe 14 moves downward relative to its initial position, the moving distance is a negative value. When there is only one probe 14, the tension conversion device 15 converts the moving distance of the probe 14 into the tension of the fiber filament. When there are two probes 14, the tension conversion device 15 converts the average moving distance of the two probes 14 into the tension of the fiber filament. When multiple detectors 14 are used, the tension conversion device 15 converts the average moving distance of the multiple detectors 14 into the tension of the fiber filament. The tension conversion device 15 can convert the moving distance of the detectors 14 into the tension of the fiber filament by using a sensor built into the tension conversion device 15 to convert the moving distance of the detectors 14 into a tension value corresponding to the moving distance. The moving distance of the detectors 14 and the corresponding tension value can be preset within the tension conversion device 15.

[0025] In this embodiment, a guide roller 12 is slidably connected to a slide rail 11. The detection bracket 13 and the probe 14 can move synchronously with the guide roller 12. When the tension of the fiber increases, the fiber is tightened and lifts the guide roller 12, moving it upwards along the sliding direction of the slide rail 11. The detection bracket 13 and the probe 14 move upwards synchronously with the guide roller 12. The tension conversion device 15 detects the movement distance of the probe 14 in real time and converts this movement distance into the tension of the fiber, thus achieving automatic detection of the fiber tension. When the tension of the fiber decreases, the guide roller 12 presses down on the fiber under its own weight and drives the fiber to move downwards along the sliding direction of the slide rail 11. The detection bracket 13 and the probe 14 move downwards synchronously with the guide roller 12. The tension conversion device 15 converts the movement distance of the probe 14 into the tension of the fiber. The tension conversion device 15 detects the movement distance of the probe 14 in real time and converts it into the tension of the fiber, thus achieving automatic detection of the fiber tension. By automatically and in real-time detecting the tension of the fiber filaments, the detection accuracy is improved, the cost of manual detection is reduced, and the errors of manual detection are avoided, thereby improving the production quality of the fiber filaments.

[0026] In some embodiments, the tension conversion device 15 is preset with the tension of the fiber corresponding to the moving distance of the probe 14. When the tension conversion device 15 detects the moving distance of the probe 14 in real time, it can quickly obtain the tension of the fiber corresponding to the moving distance. This design helps to improve the calculation speed of the tension conversion device 15 in obtaining the fiber tension and ensures the real-time acquisition of the fiber tension.

[0027] In some embodiments, such as Figure 1 As shown, the probe 14 includes a fixing part 141 and a connecting part 142. The fixing part 141 is fixed to the detection bracket 13, ensuring that the probe 14 moves synchronously with the guide roller 12. Exemplarily, the fixing part 141 can be configured as a detection head. The first end of the connecting part 142 is connected to the fixing part 141, and the second end of the connecting part 142 is disposed inside the tension conversion device 15. The connecting part 142 moves synchronously with the fixing part 141. The tension conversion device 15 detects the movement distance of the second end of the connecting part 142 and converts the movement distance into the tension of the fiber filament. Exemplarily, when the connecting part 142 moves upward relative to its initial position, the movement distance is positive; when the connecting part 142 moves downward relative to its initial position, the movement distance is negative. This design allows the tension conversion device 15 to automatically and in real-time detect the movement distance of the connecting part 142 to obtain the tension of the fiber filament, reducing the cost of manual inspection, avoiding errors in manual inspection, improving inspection accuracy, and thus improving the production and processing quality of the fiber filament.

[0028] In some embodiments, such as Figure 1 As shown, the slide rail assembly also includes two sliders 16, which are slidably connected to the slide rail 11. The guide roller 12 is fixed to the sliders 16 at both ends in the axial direction, and the detection bracket 13 is fixed to the sliders 16. When the sliders 16 move along the sliding direction of the slide rail 11, they can drive the guide roller 12 and the detection bracket 13 to move synchronously, thereby causing the probe 14 to move synchronously with the detection bracket 13. The tension conversion device 15 detects the moving distance of the probe 14 and converts this moving distance into the tension of the fiber filament. This design facilitates the movement of the guide roller 12, the detection bracket 13, and the probe 14 along the slide rail 11 via the sliders 16, ensuring that the moving trajectories of the guide roller 12, the detection bracket 13, and the probe 14 are consistent, avoiding displacement errors between components, and improving the accuracy of tension measurement.

[0029] In some embodiments, such as Figure 1 As shown, the guide roller 12 is provided with bearing seats 17 at both ends in the axial direction. The bearing seats 17 are connected to the corresponding sliders 16. The guide roller 12 and the sliders 16 are fixedly connected through the bearing seats 17, so that the guide roller 12 can rotate relative to the sliders 16. During the fiber filament passage, the fiber filament can drive the guide roller 12 to rotate through friction, thereby making the fiber filament passage process smoother.

[0030] In some embodiments, the bearing housing 17 is provided with an oil injection hole, which is used to add lubricating oil into the bearing housing 17. This helps to reduce the frictional resistance when the guide roller 12 rotates, ensures the smoothness and stability of the guide roller 12 rotation, avoids instantaneous fluctuations in the tension of the fiber due to jamming, further improves the accuracy of tension detection, and extends the service life of the bearing housing 17 and the guide roller 12.

[0031] In some embodiments, such as Figure 1 As shown, the tension detection device 1 also includes a support frame 18 and a base 19. The slide rail 11 is connected to the support frame 18, and the support frame 18 supports the slide rail 11. For example, the support frame 18 can be configured as a frame structure. The base 19 is connected to the support frame 18 and is used to support the support frame 18. By fixing the slide rail 11 to the support frame 18 and fixing the support frame 18 to the base 19, it is beneficial to ensure the connection reliability of the slide rail 11, thereby ensuring the stability of the guide roller 12, the detection bracket 13 and the probe 14 when they move along the slide rail 11, thus ensuring the accuracy of fiber tension detection and facilitating the improvement of fiber production quality.

[0032] In some embodiments, such as Figure 1As shown, the tension detection device 1 also includes a locking device 110, which is connected to the support frame 18. The locking device 110 has a locked state and an open state. In the locked state, the locking device 110 fixes the tension conversion device 15. The locking device 110 can fix the tension conversion device 15 by clamping or magnetic attraction. In the open state, the locking device 110 releases the tension conversion device 15, and at this time, the locking device 110 no longer restricts the tension rotation device to the support frame 18. With this design, by fixing the tension conversion device 15 with the locking device 110, the tension conversion device 15 can remain stationary when the probe 14 moves. This is beneficial to improving the detection accuracy of the movement distance of the probe 14 by the tension conversion device 15, thereby improving the detection accuracy of the fiber tension. This is beneficial to accurately control the fiber production process based on the fiber tension and improve the production quality of the fiber.

[0033] In some embodiments, the tension detection device 1 further includes a control device 112 electrically connected to the locking device 110 and the tension conversion device 15. The control device 112 is configured to switch the locking device 110 to an open state when the guide roller 12 moves to a preset position on the slide rail 11. Exemplarily, the preset position may be a preset height position or a preset moving distance. This design allows the locking device 110 to switch to an open state to release the tension conversion device 15 when the guide roller 12 moves to the preset position on the slide rail 11. The tension conversion device 15 can then be ejected from the locking device 110, preventing excessive tension in the fiber filaments from causing excessive movement of the guide roller 12 and the detection element 14, thereby avoiding damage to the tension conversion device 15.

[0034] In some embodiments, such as Figure 1 As shown, the tension detection device 1 also includes a limit switch 111, which is set at a preset position on the slide rail 11 and electrically connected to the control device 112. Exemplarily, the preset position is located at the upper end of the slide rail 11. When the tension of the fiber is too high and causes the guide roller 12 to move upward to the preset position on the slide rail 11, the limit switch 111 sends an alarm signal to the control device 112. Upon receiving the alarm signal, the control device 112 instructs the locking device 110 to switch to the open state. The locking device 110 switches to the open state and releases the tension conversion device 15, which is then ejected, thus protecting the tension conversion device 15 from damage. This design allows for automatic protection of the tension conversion device 15 without manual intervention, improving the automation and safety of the production process.

[0035] In some embodiments, such as Figure 1As shown, the control device 112 includes a display 1121, which displays the tension of the fiber filament. The tension conversion device 15 converts the movement distance of the probe 14 into the tension of the fiber filament and sends it to the control device 112 in the form of a preset electrical signal. The control device 112 converts the preset electrical signal into a corresponding tension value and displays it on the display screen. For example, the preset electrical signal uses a 4mA-20mA current signal, and the detection range of the tension value corresponding to the preset electrical signal is 100NM-200NM. This design allows for real-time automated detection and display of the fiber filament tension value, enabling production personnel to monitor the changes in fiber bundle tension in real time, reducing manual measurement costs, and making the detection of fiber filament tension value more convenient and faster.
