Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically a carbon fiber yarn rack with a yarn breakage alarm. Background Technology

[0002] Carbon fiber yarn, as a key raw material for manufacturing high-performance carbon fiber composites, directly determines the mechanical properties and yield of the final carbon fiber plate product due to its quality stability. In the production process of carbon fiber plates, it is typically necessary to simultaneously supply carbon fiber yarns drawn from hundreds of independent rollers. This centralized processing is not a simple physical collection, but rather a means to achieve specific layup designs and structural requirements. By precisely arranging and integrating yarns from different axes and rollers on a yarn rack, it is ensured that each yarn maintains the set tension, position, and angle when entering subsequent impregnation, preforming, and curing processes. This guarantees a uniform distribution of carbon fiber in the matrix, resulting in carbon fiber plates with consistent fiber volume content and the expected anisotropic properties.

[0003] However, in the aforementioned production system composed of a large number of yarns, carbon fiber yarns themselves are fine in diameter, high in strength but brittle, and are extremely prone to breakage due to friction, vibration, or inherent defects under high-speed operation and high tension conditions. When hundreds or thousands of yarns are running simultaneously on the production line, the breakage of a single or localized yarn is difficult for operators to detect visually in a timely manner. If yarn breakage is not detected and addressed immediately, it will continue to lead to the loss of that fiber, causing localized resin-rich areas or dry yarn defects in the composite material, seriously affecting the structural integrity of the product. In more serious cases, broken yarns may become entangled in equipment or accumulate in the mold flow channel, eventually causing mold blockage accidents, forcing the entire line to shut down, resulting in huge economic losses. Currently, most production sites still rely on manual inspection to monitor the yarn status. This not only increases the labor intensity and tediousness of workers, but also, due to the ease with which the human eye fatigues and the difficulty in concentrating for long periods, inevitably leads to oversights and omissions, failing to meet the stringent requirements of "zero defects" in quality and "zero interruptions" in modern carbon fiber plate production.

[0004] Based on this, a carbon fiber yarn holder with a yarn breakage alarm is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-8 As shown, a carbon fiber yarn rack with a yarn breakage alarm includes a yarn storage rack body 11 and warning components 12. The yarn storage rack body 11 has several yarn rollers 37 inside. Several warning components 12 are evenly spaced at the ends of the yarn storage rack body 11. Each warning component 12 includes a main mounting plate 13. Two sets of alarm components are provided at both ends of the main mounting plate 13. Each alarm component includes a first mounting frame 14 and a second mounting frame 15. The first mounting frame 14 and the second mounting frame 15 are respectively disposed on both sides of the main mounting plate 13. Several first yarn holes are arrayed on one side of each of the first mounting frame 14 and the second mounting frame 15. One side of the main mounting plate 13 is connected to the first yarn breakage alarm. A second thread hole is provided at the first thread hole. A guide roller 16 is provided inside the first mounting frame 14 and at the first thread hole. A support frame is rotatably provided on the outside of the guide roller 16. The support frame is fixedly installed at the bottom inside the first mounting frame 14. A sliding ring 17 is provided inside the first mounting frame 14 at the coaxial position with the first thread hole. An alarm mechanism for alarming when the yarn breaks is provided at the upper inside of the first mounting frame 14. A fixing mechanism for fixing the broken yarn is provided at the bottom inside the first mounting frame 14 and the second mounting frame 15. The alarm mechanism can provide timely reminder when the yarn breaks, and the fixing mechanism can fix the broken yarn. Each sliding ring 17 is provided with two sliding frames. The inner side of the first mounting frame 14 is provided with a limiting groove corresponding to the position of the sliding frame. The end of the sliding frame is T-shaped. In use, when the yarn on the yarn roller 37 passes through the first yarn hole and the second yarn hole, the yarn passes through the middle of the sliding ring 17. The sliding ring 17 acts on the yarn. When the yarn breaks, the sliding ring 17 slides downward under its own weight.

[0025] The warning mechanism includes a photoelectric switch transmitter 18 and a photoelectric switch receiver 20. A partition is fixedly provided at the bottom of the sliding ring 17. The photoelectric switch transmitter 18 and photoelectric switch receiver 20 are respectively provided on both sides of the partition. Several photoelectric switch transmitters 18 are fixedly provided on one side of the second mounting rod 21. The second mounting rod 21 is fixedly provided inside one side of the first mounting frame 14. Several photoelectric switch receivers 20 are fixedly provided on one side of the first mounting rod 19. The first mounting rod 19 is fixedly provided in the mounting groove on one side of the support frame. In use, when the yarn breaks, the sliding ring 17 moves the partition between the photoelectric switch transmitter 18 and the photoelectric switch receiver 20 under its own weight. At this time, the photoelectric switch receiver 20 cannot receive the light beam emitted by the output end of the photoelectric switch transmitter 18.

[0026] The fixing mechanism includes a fixing frame 22 and a clamping plate 24. The bottom of the first mounting frame 14 and the second mounting frame 15 are both provided with fixing frames 22 at positions corresponding to the sliding ring 17. One side of the fixing frame 22 is provided with a mounting hole. A rotating roller 23 is rotatably installed in the mounting hole. A clamping plate 24 is fitted above the rotating roller 23. A guide slide rod is fixedly provided at the upper end of the clamping plate 24. The guide slide rod is slidably installed in the sliding hole at the upper end of the mounting hole. A return spring 26 is provided between one end of the guide slide rod and the upper end of the fixing frame 22. The fixing frame 22 is provided with a driving component for driving the clamping plate 24 to move.

[0027] The driving assembly includes a sliding frame 25. The sliding frame 25 is fixedly mounted on the bottom end of the clamping plate 24. The sliding frame 25 is slidably disposed inside the fixed frame 22. A permanent magnet block 27 is fixedly mounted on the bottom end of each sliding frame 25. An electromagnet block 28 is mounted above each permanent magnet block 27. The electromagnet block 28 is installed inside the fixed frame 22. A third mounting rod 29 is provided on the upper end of the first mounting frame 14 and the second mounting frame 15 at one side of the fixed frame 22. The electromagnet blocks 28 above the first mounting frame 14 and the second mounting frame 15 are electrically connected to the control component 33. The two control components 33 are symmetrically arranged. A second elastic plate 34 is connected to one side of each control component 33. A conductive tube 35 is fixedly mounted on one end of each partition plate. A power supply base 31 is provided between each of the two control components 33. A first elastic plate 34 is provided on the upper end of each power supply base 31. The first elastic plate 32 is installed on one side of the fourth mounting rod 36. The fourth mounting rod 36 is fixedly installed at the bottom of the first mounting frame 14. The power supply base 31 is electrically connected to an external power source. In use, when the partition moves downward, the conductive tube 35 moves with the partition, so that the conductive tube 35 is in close contact with the two second elastic plates 34. When the sliding ring 17 moves to the bottom, the end of the conductive tube 35 is in close contact with the upper end of the first elastic plate 32, so that the control component 33 is powered on. The two control components 33 are electrically connected to the electromagnet blocks 28 at the upper end of the first mounting frame 14 and the second mounting frame 15, respectively, so that the electromagnet blocks 28 are energized and generate magnetic force. The contact surfaces of the electromagnet blocks 28 and the permanent magnet blocks 27 have the same magnetic poles, so that the first fixing rod drives the pressing plate 24 to move. The pressing plate 24 is in close contact with the rotating roller 23, thereby clamping and fixing the yarn end at the break.

[0028] Inside the second mounting bracket 15, on one side of the third mounting rod 29, a light-emitting alarm 30 is provided at a position corresponding to the fixed bracket 22. The light-emitting alarm 30 is electrically connected to the photoelectric switch receiver 20. When in use, when the photoelectric switch receiver 20 cannot receive the light source, the light-emitting alarm 30 is simultaneously powered on, causing the corresponding light-emitting alarm 30 to light up, thus facilitating the staff to quickly determine the location of the yarn breakage.

[0029] The sliding ring 17 is made of ceramic, which can increase the strength and weight of the sliding ring 17 during use.

[0030] The above embodiment discloses a carbon fiber yarn frame with a yarn breakage alarm. During use, as the yarn on the yarn roller 37 passes through the first and second yarn holes, it also passes through the middle of the sliding ring 17. The sliding ring 17 acts on the yarn. When the yarn breaks, the weight of the sliding ring 17 causes it to move the partition between the photoelectric switch transmitter 18 and the photoelectric switch receiver 20. At this time, the photoelectric switch receiver 20 cannot receive the light beam emitted from the output of the photoelectric switch transmitter 18. Simultaneously, the luminous alarm 30 is energized, causing the corresponding luminous alarm 30 to light up, thus facilitating quick identification by the operator. At the location of the yarn breakage, the conductive tube 35 moves along with the partition, causing the conductive tube 35 to be in close contact with the two second elastic plates 34. When the sliding ring 17 moves to the bottom, the end of the conductive tube 35 is in close contact with the upper end of the first elastic plate 32, causing the control component 33 to be powered on. The two control components 33 are electrically connected to the electromagnet blocks 28 at the upper ends of the first mounting frame 14 and the second mounting frame 15, respectively, so that the electromagnet blocks 28 are energized and generate magnetic force. The contact surfaces of the electromagnet blocks 28 and the permanent magnet blocks 27 have the same magnetic poles, causing the first fixing rod to drive the pressing plate 24 to move. The pressing plate 24 is in close contact with the rotating roller 23, thereby clamping and fixing the yarn end at the breakage point.

[0031] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
