Description

Technical Field

[0001] This utility model relates to a fiber sample preparation device, specifically, to a winding sample preparation device for XRD fiber testing. Background Technology

[0002] X-ray diffraction (XRD) is a commonly used material analysis technique, often used to test fiber samples. Before testing, fiber samples need to be prepared. Sample preparation is a very important part of X-ray diffraction technology, and the quality of the sample directly affects the accuracy and reliability of the test results.

[0003] Currently, the sample preparation device for X-ray diffraction (XRD) fiber testing is the fiber sample holder that comes with the instrument. Sample preparation requires first applying double-sided tape to the sample holder, then neatly and parallelly attaching each yarn sample to the holder. After arranging them neatly, they are secured with adhesive paper or tape. When finally attaching and securing the samples, another person is needed to press the yarns firmly before attaching and securing them to ensure the samples are parallel and taut. One person cannot operate this independently. Different tests using the same sample will yield inconsistencies, resulting in poor test reproducibility and significant human error. Furthermore, the tape itself contaminates the sample holder during attachment, requiring the double-sided tape to be scraped off and cleaned after each test. The tape also affects the test signal, reducing testing efficiency and leading to wasted time and resources. Currently, no effective solution has been proposed to address these technical problems.

[0004] In view of the problems in the related technologies, this utility model proposes a winding sample preparation device for XRD fiber testing to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A winding sample preparation device for XRD fiber testing includes a winding table, a yarn rack on one side of the winding table, a support frame above the winding table, a drive shaft on one side of the support frame, one end of the drive shaft passing through the support frame and connected to a drive motor, a rotating frame on the drive shaft, and six rotating frames, with a connecting plate between two rotating frames, a slide rail on the connecting plate, and a sample rack slidably connected inside the slide rail.

[0007] Furthermore, a groove is provided on one side of the slide rail, and a fixing pin is provided inside the groove. One end of the fixing pin is connected to the pull rod, and a spring is sleeved on the outside of the pull rod. One end of the spring is connected to the fixing pin, and the other end is connected to the connecting plate. A fixing hole is provided on one side of the sample holder, and the fixing hole is connected to the fixing pin. The other side of the sample holder is connected to the connecting plate through a magnet.

[0008] Furthermore, the sample holder has limiting grooves on both sides, and a connecting frame is slidably connected inside the limiting grooves. One end of the connecting frame is connected to the sample holder via a magnet. The top of the connecting frame has a threaded hole, and a screw is threaded inside the threaded hole. One end of the screw is rotatably connected to the pressure plate. A limiting rod is fixedly connected to the pressure plate, and the limiting rod is connected through the connecting frame.

[0009] Furthermore, a reflector is provided on one end of the drive shaft near the support frame, and a photoelectric sensor is provided on the support frame. The photoelectric sensor is electrically connected to the controller, which is located inside the support frame, and a display screen is provided on the outside of the support frame.

[0010] Furthermore, a moving rod is provided on one side of the drive shaft, and a first guide wire hook is provided on the moving rod. One side of the moving rod passes through the support frame and is connected to the moving block. The upper and lower sides of the moving block are connected to the slide groove. One end of the slide groove is connected to the support frame. One side of the moving block is connected to the swing rod through the hinge seat. The swing rod is connected to the rotating plate. One end of the rotating plate is connected to the speed regulating motor through the rotating rod. A mounting frame is provided on the slide groove. The mounting frame is connected to the rotating rod.

[0011] Furthermore, a fixed rod is provided on one side of the moving rod, a tensioner is provided on the fixed rod, a wire guide frame is provided on one side of the fixed rod, and a second wire guide hook is provided on the wire guide frame.

[0012] Furthermore, a control button is provided on the winding table, and the control button is electrically connected to the controller.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) By fixing the sample holder to the rotating frame, it is ensured that each yarn can be densely and parallel to the sample holder during the sample preparation process, thus ensuring that the two diffraction peaks remain symmetrical during the test and obtaining reliable test results. At the same time, this method also has good reproducibility, which means that consistent results can be obtained in repeated tests. Furthermore, by setting up a photoelectric sensor, the number of rotations of the rotating frame can be accurately located, making the sample preparation process more convenient and faster. In addition, by setting a connecting frame above the sample holder, after the sampling is completed, the yarn sample can be fixed by rotating the screw to drive the pressure plate to press down, without damaging the sample, and facilitating its recovery for other tests.

[0015] (2) By setting up a speed-regulating motor, a swing rod, and a moving block, when the speed-regulating motor starts, it transmits power to the swing rod through the transmission mechanism, causing it to swing periodically. The swinging motion of the swing rod is transmitted to the moving block through the connecting mechanism, thereby causing the moving block to move left and right in the horizontal direction. At the same time, the movement of the moving block is transmitted to the moving rod through the connecting rod, causing it to move back and forth in the horizontal direction. The key to this design is that the back and forth movement of the moving rod can ensure that the yarn is evenly distributed on the sample holder during the winding process. In this way, we can effectively avoid problems such as yarn aggregation, overlap, or gaps during the winding process, thereby ensuring the stability and consistency of the winding quality.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] According to an embodiment of the present invention, a winding sample preparation device for XRD fiber testing is provided.

[0025] Example 1

[0026] like Figures 1-4 As shown, the winding sample preparation device for XRD fiber testing according to an embodiment of the present invention includes a winding table 1, a yarn rack 2 on one side of the winding table 1, a support frame 3 above the winding table 1, a drive shaft 4 on one side of the support frame 3, one end of the drive shaft 4 passing through the support frame 3 and connected to a drive motor 5, a rotating frame 6 on the drive shaft 4, and six rotating frames 6 in total, with a connecting plate 7 between two rotating frames 6, a slide rail 8 on the connecting plate 7, a sample holder 9 slidably connected inside the slide rail 8, a groove 10 on one side of the slide rail 8, a fixing pin 11 inside the groove 10, one end of the fixing pin 11 connected to a pull rod 12, a spring 13 sleeved on the outside of the pull rod 12, one end of the spring 13 connected to the fixing pin 11, and the other end connected to the connecting plate 7, a fixing hole 14 on one side of the sample holder 9 connected to the fixing pin 11, and the other side of the sample holder 9 connected to the connecting plate 7 by a magnet.

[0027] like Figures 1-4As shown, the sample holder 9 has limiting grooves 15 on both sides, and a connecting frame 16 is slidably connected inside the limiting grooves 15. One end of the connecting frame 16 is connected to the sample holder 9 by a magnet. The top of the connecting frame 16 has a threaded hole 17, and a screw 18 is threadedly connected inside the threaded hole 17. One end of the screw 18 is rotatably connected to the pressure plate 19. A limiting rod 20 is fixedly connected to the pressure plate 19. The limiting rod 20 is connected through the connecting frame 16. The limiting rod 20 is used to prevent the pressure plate 19 from shifting position. A reflector 21 is provided on the end of the drive shaft 4 near the support frame 3. A photoelectric sensor 22 is provided on the support frame 3. The photoelectric sensor 22 is electrically connected to the controller 23. The controller 23 is located inside the support frame 3. A display screen 24 is provided on the outside of the support frame 3. A control button 37 is provided on the winding table 1. The control button 37 is electrically connected to the controller 23. With the above scheme, the rolled yarn is placed on the yarn holder 2, and then the sample holder 9 slides inside the slide rail 8. The sample holder 9 is positioned by the fixing pin 11 and then fixed inside the slide rail 8 by the magnet. When the yarn is transferred to the rotating frame 6, the drive motor 5 is started to drive the rotating frame 6 to rotate, so that the yarn sample can be wound on the sample holder 9. When the reflector on the drive shaft 4 passes the photoelectric sensor 22, the photoelectric sensor 22 can detect the change in light signal.

[0028] This detection is achieved through the photoelectric element inside the photoelectric sensor 22. When the light signal changes, the photoelectric element generates a corresponding change in electrical signal. Once the photoelectric sensor 22 detects a change in the light signal, it can transmit an output signal to the connected controller 23. This output signal is usually a pulse signal, with each pulse representing a change in the light signal. When the controller 23 receives a change in the light signal, it can read and count the pulse signals from the photoelectric sensor 22. After sample preparation, the connecting frame 16 can be placed inside the limiting groove 15 through both ends and fixed with magnets. Then, by rotating the screw 18, the pressure plate 19 is pressed down to fix the yarn sample. The yarn on both sides of the sample holder 9 is then cut, and the sample holder 9 can be disassembled by pulling the pull rod 12 to release the fixation.

[0029] Example 2

[0030] like Figures 1-4As shown, a movable rod 25 is provided above the winding table 1. The movable rod 25 is located on one side of the drive shaft 4. A first guide hook 26 is provided on the movable rod 25. One side of the movable rod 25 passes through the support frame 3 and is connected to the movable block 27. The upper and lower sides of the movable block 27 are connected to the slide groove 28. One end of the slide groove 28 is connected to the support frame 3. One side of the movable block 27 is connected to the swing rod 29 through the hinge seat. The swing rod 29 is connected to the rotating plate 30. One end of the rotating plate 30 is connected to the speed regulating motor 31 through the rotating rod. A mounting frame 32 is provided on the slide groove 28. The mounting frame 32 is connected to the rotating rod. A fixed rod 33 is provided on one side of the movable rod 25. A tensioner 34 is provided on the fixed rod 33. A guide frame 35 is provided on one side of the fixed rod 33. A second guide hook 36 is provided on the guide frame 35. Through the above scheme, the yarn is conveniently conveyed by the second guide hook 36, and then the yarn passes through the tensioner 34, which can control the tension of the yarn to ensure that the tension of the yarn remains stable during the winding process, avoiding yarn breakage or loosening due to uneven tension. Then, by passing the yarn through the first guide hook 26, the speed-regulating motor 31 is started, which can drive the rotating plate 30 to rotate. The rotation of the rotating plate 30 drives the swing rod 29 to move, which can drive the moving block 27 to move inside the slide groove 28, thereby driving the yarn inside the first guide hook 26 to move left and right, so that the yarn is evenly distributed on the sample holder 9 during the winding process.

[0031] In practical applications, by fixing the sample holder 9 to the rotating frame 6, it is ensured that the yarns are densely and parallelly fixed on the sample holder 9 during sample preparation, guaranteeing that the two diffraction peaks remain symmetrical during testing, thus obtaining reliable test results. Simultaneously, this method also exhibits good reproducibility, meaning consistent results can be obtained in repeated tests. Furthermore, by setting up the photoelectric sensor 22, the number of rotations of the rotating frame 6 can be accurately located, making the sample preparation process more convenient and faster. Additionally, by setting up the connecting frame 16 above the sample holder 9, after sampling, the rotating screw 18 can drive the pressure plate 19 to press down and fix the yarn sample without damaging it, facilitating recovery for other tests. Finally, by setting up the speed-regulating motor 31, the swing rod 29, and the moving block 27, when the speed-regulating motor 31 is started, it transmits power to the swing rod 29 through the transmission mechanism, causing it to oscillate periodically. The oscillating motion of the swing rod 29 is transmitted to the moving block 27 through the connecting mechanism, thereby causing the moving block 27 to move left and right in the horizontal direction. At the same time, the movement of the moving block 27 is transmitted to the moving rod 25 through the connecting rod, so that it moves back and forth in the horizontal direction to ensure the stability and consistency of the winding quality.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
