Description

Technical Field

[0001] This utility model relates to the field of twisting device technology, specifically a twisting device for carbon fiber coated yarn. Background Technology

[0002] In the modern textile and composite materials field, the demand for high-performance, multi-functional yarns is increasing. Carbon fiber, due to its superior properties such as high strength, high modulus, and low density, is widely used in aerospace, automotive, sporting goods, and many other fields. Composite carbon fiber with ordinary yarn to create carbon fiber-coated yarn retains the flexibility and processability of ordinary yarn while imparting the high-performance characteristics of carbon fiber.

[0003] Publication No. CN221028866U discloses a carbon fiber coated yarn twisting device, including a base, a twisting mechanism on the left side of the top wall of the base, a fixing frame on the top wall of the base, support rollers on both the left and right sides of the top wall of the fixing frame, an adjusting screw on the top wall of the fixing frame, and adjusting frames on the front and rear side walls of the inner cavity of the fixing frame. By setting up the base, fixing frame, and support rollers in cooperation, the device can easily adjust the tension of the yarn, avoid the yarn from slack and tangling, and facilitate subsequent winding operations.

[0004] As shown in the above technical solution, although the device adjusts the tension of the yarn through the support roller, when the position of the support roller changes and the tension of the yarn changes, this change in friction will generate an additional pulling force on the yarn. Since the yarn is wound on the yarn roller, this additional force may be transmitted to the yarn roller, causing the yarn roller to rotate. The unexpected rotation of the yarn roller will make it difficult to accurately control the length and speed of the yarn release, making it difficult to maintain a stable ratio of yarn to carbon fiber yarn during the twisting process, thus affecting the quality of carbon fiber coated yarn.

[0029] 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.

[0030] See Figures 1-6 This utility model provides the following two technical solutions:

[0031] First embodiment: A carbon fiber coated yarn twisting device, comprising:

[0032] Mounting platform 1 is used to provide a stable mounting base and support platform for all components of the entire twisting device;

[0033] The wire feeding assembly 2 includes a first wire feeding frame 21 and a second wire feeding frame 22. The first wire feeding frame 21 is fixedly installed at the front end of the top of the mounting platform 1. A first sliding groove 23 is provided at the rear end of the top of the mounting platform 1. The second wire feeding frame 22 is slidably installed in the first sliding groove 23. Three wire feeding shafts 24 are rotatably mounted on both the first wire feeding frame 21 and the second wire feeding frame 22. A first motor 25 is fixedly installed on the first wire feeding frame 21. The output end of the first motor 25 is fixedly connected to the wire feeding shaft 24 located in the middle of the first wire feeding frame 21. The output end of the second wire feeding frame 22 is fixedly connected to the wire feeding shaft 24 located in the middle of the first wire feeding frame 21. A first gear 26 is fixedly installed on the outer end of the pay-off shaft 24. A second gear 27 is fixedly installed on the outer ends of the other two pay-off shafts 24 on the second pay-off frame 22. Both second gears 27 are meshed with the first gear 26. A first mounting block 28 is fixedly installed on the inner end of each of the six pay-off shafts 24. A first mounting groove 29 matching the first mounting block 28 is opened at both ends of the yarn winding roller 3 and the carbon fiber winding roller 4. The yarn winding roller 3 is used to place the base yarn that needs to be covered, and the carbon fiber winding roller 4 is used to place the carbon fiber yarn that is used to cover the yarn.

[0034] The twisting assembly 5 is fixedly installed on the middle side of the top of the mounting platform 1. The twisting assembly 5 is used to effectively twist the yarn and carbon fiber yarn released from the yarn release assembly 2, so that the carbon fiber yarn is evenly wrapped on the outside of the yarn.

[0035] The take-up assembly 6 is fixedly installed on the right side of the top of the mounting platform 1. The take-up assembly 6 is used to collect and wind the carbon fiber coated yarn that has been twisted by the twisting assembly 5 in an orderly manner.

[0036] Both the second wire feeding frame 22 and the mounting platform 1 have two first slots 7. Two first pins 8 are installed between the second wire feeding frame 22 and the mounting platform 1. Both first pins 8 are movably installed in the first slots 7 on the second wire feeding frame 22 and the mounting platform 1.

[0037] The first motor 25 on the second pay-off frame 22 drives the pay-off shaft 24 located in the middle to rotate. The first gear 26 at the outer end of the pay-off shaft 24 rotates accordingly. Since both second gears 27 are meshed with the first gear 26, the other two pay-off shafts 24 will also rotate synchronously, thus ensuring that the three pay-off shafts 24 on the same pay-off frame can pay off the yarn synchronously, allowing the yarn and carbon fiber to be paid off at a stable speed. The second pay-off frame 22 is slidably installed at the first slide groove 23 at the rear end of the top of the mounting platform 1. By adjusting the position of the second pay-off frame 22, the space between the pay-off shafts 24 can be increased. The yarn winding roller 3 and carbon fiber winding roller 4 can be removed and installed, reducing the time and labor costs required to replace the rollers and improving production efficiency. At the same time, the position of the second feeding frame 22 can be adjusted by inserting and pulling the first pin 8 into and out of the first slot 7 on the mounting platform 1. The twisting assembly 5 is fixedly installed on the middle side of the top of the mounting platform 1. The yarn and carbon fiber wire released from the feeding assembly 2 enter the twisting assembly 5. The twisting assembly 5 performs an effective twisting operation on the yarn and carbon fiber wire, so that the carbon fiber wire is evenly wrapped on the outside of the yarn to form a carbon fiber wrapped yarn.

[0038] In this embodiment, the cooperation between the first mounting block 28 and the first mounting groove 29 ensures the stable installation of the yarn winding roller 3 and the carbon fiber winding roller 4 on the pay-off shaft 24, preventing the roller from rotating during the pay-off process, thereby ensuring the stable release of the yarn and carbon fiber. The meshing transmission of the first gear 26 and the second gear 27 realizes the synchronous rotation of the three pay-off shafts 24 on the same pay-off frame, so that the yarn and carbon fiber can be released at the same time, which is beneficial to the subsequent twisting operation.

[0039] The second embodiment differs from the first embodiment in that the twisting assembly 5 includes a twisting frame 51. A third gear 52 and a fourth gear 53 are rotatably mounted on the inner end of the twisting frame 51. The third gear 52 and the fourth gear 53 are meshed together. The third gear 52 has a yarn hole 54 and two carbon fiber holes 55. The two carbon fiber holes 55 are located on the upper and lower sides of the yarn hole 54, respectively. A wire cone 56 and a second motor 57 are fixedly mounted on the outer end of the twisting frame 51. The output end of the second motor 57 passes through the twisting frame 51 and is fixedly connected to the fourth gear 53.

[0040] The take-up assembly 6 includes a first take-up frame 61 and a second take-up frame 62. The first take-up frame 61 is fixedly installed on the top of the mounting platform 1. A second slide groove 63 is provided on the mounting platform 1. The second take-up frame 62 is slidably installed in the second slide groove 63. Take-up shafts 64 are rotatably installed on the inner ends of both the first take-up frame 61 and the second take-up frame 62. The same take-up roller 65 is movably installed between the two take-up shafts 64. A second mounting block 66 is fixedly installed on the inner ends of both take-up shafts 64. Second mounting grooves 67 matching the second mounting blocks 66 are provided at both ends of the take-up roller 65. A third motor 68 is fixedly installed on the first take-up frame 61. The output end of the third motor 68 is fixedly connected to the take-up shaft 64 on the first take-up frame 61.

[0041] Both the second take-up frame 62 and the mounting platform 1 have two second slots 9. Two second pins 10 are installed between the take-up assembly 6 and the mounting platform 1. The second pins 10 are movably installed in the second slots 9 on the second take-up frame 62 and the mounting platform 1.

[0042] A wire support 11 is installed between the wire feeding assembly 2 and the first pin 8. The wire support 11 is fixedly installed on the top of the mounting platform 1. Three wire slots 12 are provided on the wire support 11, and cleaning cotton 13 is movably installed in each of the three wire slots 12.

[0043] After the second motor 57 starts, its output drives the fourth gear 53 to rotate. Since the third gear 52 is meshed with the fourth gear 53, the rotation of the fourth gear 53 will drive the third gear 52 to rotate in the opposite direction. The base yarn to be coated passes through the yarn hole 54, and the carbon fiber yarns used for coating pass through the two carbon fiber yarn holes 55 respectively. As the third gear 52 rotates, the two carbon fiber yarns are wrapped around the yarn during rotation, thereby achieving the twisting operation of evenly coating the carbon fiber yarns on the outside of the yarn. The conductor cone 56 serves to remove the coated yarn from the twisting area. The take-up roller 65 passes through the second mounting at both ends. The groove 67 engages with the second mounting block 66 on the inner end of the take-up shaft 64 and is movably mounted between the two take-up shafts 64. When the take-up shaft 64 rotates, it drives the take-up roller 65 to rotate as well, collecting and winding the carbon fiber coated yarn after it has been twisted by the twisting assembly 5. The second take-up frame 62 is slidably mounted at the second slide groove 63. By pulling out or inserting the second pin 10 mounted at the second slot 9 on the mounting platform 1, the position of the second take-up frame 62 can be adjusted, facilitating the replacement of the take-up roller 65. The yarn and carbon fiber yarn released from the pay-off assembly 2 pass through the three guide grooves 12 on the guide frame 11. The guide grooves 12 guide the direction of the yarn, allowing it to accurately enter the twisting assembly 5. At the same time, the cleaning cotton 13 movably mounted at the guide grooves 12 can clean the surface of the yarn and carbon fiber yarn as they pass through, removing impurities and dust.

[0044] In this embodiment, the rotation of the third gear 52 is achieved through gear transmission, which enables the yarn and carbon fiber thread to be twisted together quickly and evenly during rotation, improving twisting efficiency and quality. The guide groove 12 ensures that the yarn and carbon fiber thread can accurately enter the twisting assembly 5, avoiding confusion or deviation of the thread during transmission, ensuring the smooth progress of the twisting process. The cleaning cotton 13 cleans the surface of the yarn and carbon fiber thread, which helps to improve the twisting quality, reduce twisting defects caused by impurities and dust, and improve product quality.

[0045] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0046] In use, the first motor 25 is turned on, which drives the pay-off shaft 24 located in the middle of the first pay-off frame 21 to rotate. At the second pay-off frame 22, the first gear 26 at the outer end of the middle pay-off shaft 24 rotates along with it. Through meshing with the two second gears 27, it drives the other two pay-off shafts 24 to rotate synchronously, thereby allowing the yarn winding roller 3 and the carbon fiber winding roller 4 to release yarn and carbon fiber simultaneously. The second motor 57 is started, and the output end of the second motor 57 drives the fourth gear 53 to rotate. Since the third gear 52 is meshed with the fourth gear 53, the third gear 52 rotates in the opposite direction. As the third gear 52 rotates, the two carbon fiber threads are wound around the yarn during rotation, realizing the twisting operation of evenly covering the outside of the yarn with carbon fiber threads. The third motor 68 is started, and the output end of the third motor 68 drives the take-up shaft 64 to rotate. The rotation of the take-up shaft 64 drives the take-up roller 65 to rotate together, so as to collect and wind the carbon fiber covered yarn that has been twisted by the twisting component 5 in an orderly manner.
