Under different working conditions, the upper and lower yarn clamping blocks in the yarn clamping device will move up and down, and the carbon fiber yarn surface held by the upper and lower yarn clamping blocks will also move up and down accordingly. The up and down movement of the carbon fiber yarn surface will lead to the occurrence of yarn tangling, which affects the quality of processing. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a carbon fiber yarn breakage lifting device, comprising a yarn breakage base, an upper yarn clamping block, and a lower yarn clamping block. Two mounting brackets are fixedly connected to the top of the yarn breakage base, and two support rollers are rotatably connected between the two mounting brackets. Multiple drive shafts are arranged on one side of the upper yarn clamping block, and support rollers are rotatably sleeved on the outer sides of each of the multiple drive shafts. A flipping assembly is arranged between the multiple drive shafts and the upper yarn clamping block. Multiple drive shafts are arranged on one side of the lower yarn clamping block, and support rollers are rotatably sleeved on the outer sides of each of the multiple drive shafts. An elastic lifting assembly is arranged between the multiple drive shafts and the lower yarn clamping block.
[0005] Preferably, a dual-axis hydraulic cylinder is fixedly connected between the upper and lower yarn clamping blocks, and two guide rods are fixedly connected to the top of the yarn breakage base, with the top ends of the two guide rods passing through the lower and upper yarn clamping blocks in sequence.
[0006] Preferably, a pneumatic cylinder is fixedly connected to the top of the yarn breakage base, and a connecting plate is fixedly connected between the top of the pneumatic cylinder and the dual-axis hydraulic cylinder. A reserved groove 2 is provided on one side of the lower yarn clamping block, and the reserved groove 2 is located on the top of the pneumatic cylinder.
[0007] Preferably, the flipping assembly includes a forward and reverse motor 1 fixedly connected to one side of the upper yarn clamping block, a transmission shaft 1 fixedly connected to the output end of the forward and reverse motor 1, and a mounting bracket 2 rotatably connected to one end of the transmission shaft 1. One end of the transmission shaft 1 passes through multiple transmission shafts 2 and is fixedly connected to the multiple transmission shafts 2.
[0008] Preferably, two telescopic rods are fixedly connected between the mounting bracket 2 and the yarn breakage base, and a reserved groove 1 is provided on one side of the bottom of each of the multiple transmission shafts 2, and the reserved groove 1 is formed on one side of the top of the yarn breakage base.
[0009] Preferably, the elastic lifting assembly includes a drive shaft three that passes through multiple drive shafts four, a mounting frame three fixedly connected to one end of the drive shaft three, and a mounting frame four fixedly connected to the other end of the drive shaft three. The drive shaft three is fixedly connected to multiple drive shafts four. Two spring-type telescopic rods one are fixedly connected between the bottom of the mounting frame three and the yarn breakage base. Multiple spring-type telescopic rods two are fixedly connected to the top of the mounting frame four.

[0010] Preferably, a transmission frame is sleeved on the outer side of the transmission shaft three, a pull wire is fixedly connected to the bottom of the transmission frame, a take-up frame is fixedly connected to one end of the pull wire, a forward and reverse motor two is fixedly connected to the top of the yarn breakage base, and the take-up frame is fixedly sleeved on the output end of the forward and reverse motor two.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. In this application, multiple support rollers 2 support and limit the top of the carbon fiber yarn surface, and multiple support rollers 3 support and limit the bottom of the carbon fiber yarn surface. The control pneumatic cylinder drives the dual-axis hydraulic cylinder to move up and down. When the dual-axis hydraulic cylinder drives the fixed lower clamping yarn block and the upper clamping yarn block to move up or down synchronously, the transmission shaft 3 and the transmission shaft 1 move up and down synchronously. The multiple support rollers 2 and 3 move up and down synchronously. The multiple rotatable support rollers 2 and 3 support and limit the carbon fiber yarn surface, avoiding a large increase in the friction force on the normally moving carbon fiber yarn surface. This effectively avoids the phenomenon of yarn tangling on the carbon fiber yarn surface when the upper and lower clamping yarn blocks holding the carbon fiber move up and down as a whole, ensuring the quality of processing.
[0013] 2. In this application, the forward and reverse motor 1 operates in reverse, and the transmission shaft 1 drives the fixedly connected transmission shaft 2 and the support roller 2 rotated around the transmission shaft 1 as a whole. After the multiple support rollers 2 rotate 270°, the support rollers 2 are perpendicular to the yarn breakage base. At this time, the support rollers 2 are far away from the carbon fiber yarn surface. The setting of the support rollers 2 will not affect the normal operation of the upper and lower yarn clamping blocks. Attached Figure Description

[0019] 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.
[0020] Example: Figures 1-4 As shown, this utility model provides a technical solution for a carbon fiber yarn breakage lifting device, including a yarn breakage base 1, an upper yarn clamping block 5, and a lower yarn clamping block 6. Two mounting brackets 3 are fixedly connected to the top of the yarn breakage base 1, and two support rollers 4 are rotatably connected between the two mounting brackets 3. Multiple transmission shafts 16 are provided on one side of the upper yarn clamping block 5, and support rollers 17 are rotatably sleeved on the outer side of each of the multiple transmission shafts 16. A flipping component is provided between the multiple transmission shafts 16 and the upper yarn clamping block 5. Multiple transmission shafts 19 are provided on one side of the lower yarn clamping block 6, and support rollers 20 are rotatably sleeved on the outer side of each of the multiple transmission shafts 19. An elastic lifting component is provided between the multiple transmission shafts 19 and the lower yarn clamping block 6.
[0021] Specifically, two mounting brackets 3 are fixedly connected to the top of the yarn breakage base 1, and two support rollers 4 are rotatably connected between the two mounting brackets 3. After passing through the two support rollers 4, the carbon fiber yarn is guided and its displacement is restricted by the two rotatable support rollers 4.
[0022] Two guide rods 8 are fixedly connected to the top of the yarn breakage base 1. The tops of the two guide rods 8 pass through the lower yarn clamping block 6 and the upper yarn clamping block 5 in sequence. Under the limiting guidance of the two guide rods 8, the upper yarn clamping block 5 and the lower yarn clamping block 6 can only move up and down. A pneumatic cylinder 9 is fixedly connected to the top of the yarn breakage base 1. A connecting plate 10 is fixedly connected between the top of the pneumatic cylinder 9 and the dual-axis hydraulic cylinder 7. When the pneumatic cylinder 9 is not working, the connecting plate 10 and the dual-axis hydraulic cylinder 7 fixedly connected to the connecting plate 10 cannot move. A reserved groove 2 11 is opened on one side of the lower yarn clamping block 6. The reserved groove 2 11 is set in the pneumatic cylinder 9. The pre-reserved slot 2 11 at the top ensures that the pneumatic cylinder 9 does not affect the up-and-down movement of the lower clamping yarn block 6; and a dual-axis hydraulic cylinder 7 is fixedly connected between the upper clamping yarn block 5 and the lower clamping yarn block 6. When the dual-axis hydraulic cylinder 7 is extended, both piston ends of the dual-axis hydraulic cylinder 7 extend simultaneously, and the dual-axis hydraulic cylinder 7 pushes the upper clamping yarn block 5 and the lower clamping yarn block 6 away from each other, making it convenient to add carbon fiber yarn between the upper clamping yarn block 5 and the lower clamping yarn block 6; when the working piston end of the dual-axis hydraulic cylinder 7 is retracted, the dual-axis hydraulic cylinder 7 drives the upper clamping yarn block 5 and the lower clamping yarn block 6 to move closer to each other, and the upper clamping yarn block 5 and the lower clamping yarn block 6 play the role of clamping carbon fiber yarn.
[0023] Example 1: When it is necessary to control the synchronous movement of the upper yarn clamping block 5 and the lower yarn clamping block 6, since the forward and reverse motor 12 in the flipping assembly is fixedly installed on one side of the upper yarn clamping block 5, and the output end of the forward and reverse motor 12 is fixedly connected to the transmission shaft 13, one end of which passes through multiple transmission shafts 16 and is fixedly connected to the multiple transmission shafts 16, at this time, multiple support rollers 17 rotatably sleeved on the outside of the transmission shafts 16 are all set on the top of the carbon fiber yarn surface. The multiple support rollers 17 support and limit the top of the carbon fiber yarn surface, and the mounting frame 14 rotatably connected to one end of the transmission shaft 13 is fixedly connected to the yarn breakage base 1 with two telescopic rods 15. The telescopic rods 15, which can extend and retract, support the mounting frame 14 and the transmission shaft 13, so the upper yarn clamping block 5 can drive the forward and reverse motor 12 and the transmission shaft 13 to move up and down synchronously.
[0024] Multiple support rollers 20, rotatably mounted on the outer side of multiple drive shafts 4 19, are positioned at the bottom of the carbon fiber yarn surface. These support rollers 20 provide support and restraint to the bottom of the carbon fiber yarn surface. In the elastic lifting assembly, drive shaft 18 passes through and is fixedly connected to multiple drive shafts 4 19. Drive shaft 18 causes the multiple drive shafts 4 19 and support rollers 20 to move up and down synchronously. Two spring-loaded telescopic rods 22 are fixedly connected between the bottom of the mounting frame 21, which is fixedly connected to one end of drive shaft 18, and the yarn breakage base 1. These spring-loaded telescopic rods 22 apply an upward thrust to the mounting frame 21 and drive shaft 18. Multiple spring-loaded telescopic rods 24 are fixedly connected to the top of the mounting frame 23, which is fixedly connected to the other end of drive shaft 18. These spring-loaded telescopic rods 24 are fixedly connected to the lower yarn clamping block 6. The frame 25, with multiple spring-loaded telescopic rods 24 moving synchronously with the lower clamping yarn block 6, applies an upward pulling force to the drive shaft 18, causing the drive shaft 18 and the lower clamping yarn block 6 to move up and down synchronously. Therefore, when the control pneumatic cylinder 9 drives the dual-axis hydraulic cylinder 7 to move up and down, and the dual-axis hydraulic cylinder 7 drives the fixed lower clamping yarn block 6 and upper clamping yarn block 5 to move up or down synchronously, the drive shaft 18 and drive shaft 13 move up and down synchronously. Multiple support rollers 17 and 20 move up and down synchronously. The multiple rotatable support rollers 17 and 20 support and limit the carbon fiber yarn surface, avoiding a significant increase in friction on the normally moving carbon fiber yarn surface. This effectively prevents the carbon fiber yarn surface from becoming tangled when the upper clamping yarn block 5 and lower clamping yarn block 6, which hold the carbon fiber, move up and down as a whole, ensuring the quality of processing.
[0025] Example 2: After the pneumatic cylinder 9 completes its work and drives the dual-shaft hydraulic cylinder 7, upper yarn clamping block 5, lower yarn clamping block 6, drive shaft 13, support roller 27, drive shaft 318, and support roller 320 to reset, the forward and reverse motor 12 can be controlled to work in reverse. The forward and reverse motor 12 drives the fixedly connected drive shaft 13 to rotate clockwise. The drive shaft 13 drives the fixedly connected drive shaft 216 and the support roller 217 rotated around the outside of the drive shaft 216, with the drive shaft 13 as the center. The shaft rotates clockwise, and multiple reserved grooves 2 set on one side of the bottom of multiple transmission shafts 16 are formed on one side of the top of the yarn breakage base 1. The position of the reserved grooves 2 provides space for the rotation of the support rollers 17. After the forward and reverse motors 12 drive the transmission shafts 13 and multiple support rollers 17 to rotate 270°, the support rollers 17 are perpendicular to the yarn breakage base 1. At this time, the support rollers 17 are away from the carbon fiber yarn surface. The setting of the support rollers 17 will not affect the normal operation of the upper yarn clamping block 5 and the lower yarn clamping block 6.
[0026] When it is necessary to control the lower clamping block 6 and the upper clamping block 5 to move up and down synchronously, the forward and reverse motor 12 can be controlled to rotate forward for a period of time. The forward and reverse motor 12 drives the transmission shaft 13 and multiple support rollers 17 to rotate counterclockwise by 270° to provide limiting support for the top of the carbon fiber yarn surface.
[0027] Furthermore, a transmission frame 26 is sleeved on the outside of the transmission shaft 3 18. One end of the pull wire 27 fixedly connected to the bottom of the transmission frame 26 is fixedly connected to the take-up frame 28. The output end of the forward and reverse motor 29 fixedly connected to the top of the yarn breakage base 1 passes through the take-up frame 28, controlling the forward and reverse motor 29 to drive the take-up frame 28 to rotate. The take-up frame 28 rotates and winds up the pull wire 27. The transmission frame 26 fixedly connected to the pull wire 27 drives the transmission shaft 3 18 to move down. At this time, the spring-type telescopic rod 24 extends and the spring-type telescopic rod 1 22 retracts. The downward movement of the transmission shaft 3 18 drives multiple transmission shafts 4 19 and the support rollers 3 20 sleeved on the outside of multiple transmission shafts 4 19 to move down, so that the support rollers 3 20 are away from the bottom of the carbon fiber yarn surface, providing sufficient space for the processing of the carbon fiber yarn surface.
[0028] When the forward and reverse motor 29 stops working, the rebounding spring-type telescopic rod 24 and spring-type telescopic rod 22 cause the transmission shaft 18 to move upward, so that the support roller 20 moves to the bottom of the carbon fiber yarn surface, and the pull line 27 has sufficient length to meet the upward movement needs of the upper clamping yarn block 5 and the lower clamping yarn block 6.
[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
