It is made from acrylic and viscose fibers through high-temperature oxidation and carbonization. It is an excellent material for manufacturing high-tech equipment in aerospace and other applications. During the processing of finished carbon fiber raw materials, the carbon fiber needs to be unwound using a winding and unwinding method, requiring an unwinding device.

[0003] However, in most existing fiber unwinding devices, the unwinding roller used for unwinding the fiber is fixed to the support frame during use, and it is inconvenient to disassemble and replace the unwinding roller. As a result, it is inconvenient to quickly replace the new unwinding roller after unwinding is completed, and the device is inconvenient to use and not practical enough. Therefore, a fiber unwinding device is proposed to address the above problems. Utility Model Content

[0024] 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.

[0025] Example 1

[0026] Please see Figure 1-5 As shown, a fiber unwinding device includes a base plate 1, a vertical plate 2 fixedly connected to the top left side of the base plate 1, and a support plate 4 fixedly connected to the top right side of the base plate 1.

[0027] An installation assembly 5 is provided between the front and rear surfaces of the vertical plate 2, and an unwinding roller 3 is provided on the right side of the vertical plate 2 through the installation assembly 5.

[0028] The support plate 4 has a through-slot 6 extending from left to right at its center. A buffer assembly 9 is provided between the front and rear surfaces of the through-slot 6. A connecting rod 8 is installed inside the buffer assembly 9, and a guide wheel 7 is rotatably connected to the outer surface of the connecting rod 8 via a bearing. During operation, the bottom of the base plate 1 is first placed against the placement surface to ensure the device is stable. After the device is stable, the carbon fiber on the unwinding roller 3 can pass through the through-slot 6 and be unwound by the guide wheel 7. During unwinding, the unwinding roller 3 rotates, and the rotation of the guide wheel 7 ensures smoother and more efficient unwinding. During the process of guiding and unwinding carbon fiber with guide wheel 7, if the carbon fiber is tightly squeezed by guide wheel 7, guide wheel 7 can be buffered by buffer component 9, so that the tightness of carbon fiber is buffered to a certain extent, thereby avoiding the carbon fiber from breaking during unwinding and making the unwinding effect better. At the same time, unwinding roller 3 is installed on the right side of vertical plate 2 through mounting component 5, and unwinding roller 3 can rotate during unwinding through mounting component 5. This makes unwinding roller 3 easy to disassemble, replace and reinstall, and can also rotate during unwinding, so that the device can meet more usage needs and has strong practicality.

[0029] The buffer assembly 9 includes a sliding groove 91 formed on the front and rear surfaces inside the through groove 6. A guide block 93 is slidably connected inside the sliding groove 91. The guide block 93 is fixedly connected to the connecting rod 8. A second spring 94 is fixedly connected between the guide block 93 and the sliding groove 91. During operation, when the carbon fiber is unwound and is taut, it squeezes the guide wheel 7. The guide wheel 7 drives the connecting rod 8 to move. Then, the connecting rod 8 drives the guide block 93 to slide inside the sliding groove 91. After the slider slides, it squeezes the second spring 94. Then, the rebound force of the second spring 94 buffers the squeeze. The guide wheel 7 can also move through the deformation of the second spring 94 to adapt to and buffer the tautness of the carbon fiber, thereby preventing the carbon fiber from breaking during unwinding.

[0030] A guide rod 92 passes through the inside of the guide block 93, and the guide rod 92 passes through the second spring 94. The guide rod 92 is fixedly connected to the inside of the slide groove 91. During operation, the guide rod 92 guides the sliding of the slider and makes the compression of the second spring 94 by the slider more stable.

[0031] The unwinding roller 3 is rotatably connected to the vertical plate 2 via the mounting assembly 5, and the unwinding roller 3 corresponds to the guide wheel 7. During operation, the unwinding roller 3 can rotate during unwinding, and the carbon fiber released from the unwinding tube can be guided by the guide wheel 7.

[0032] The mounting assembly 5 includes rectangular grooves 51 formed at the center of the front and rear surfaces of the vertical plate 2. A rectangular block 53 is slidably connected inside the rectangular groove 51. A spring 52 is fixedly connected between the rectangular block 53 and the rectangular groove 51. Mounting plates 54 are fixedly connected to opposite sides of the two rectangular blocks 53. The mounting plates 54 have through-holes 56 inside. A rotating rod 57 is rotatably connected to the mounting holes 56 via bearings. A rectangular limiting block 58 is fixedly connected to one end of the rotating rod 57. A rectangular limiting groove 59 is formed inside the unwinding roller 3. The rectangular limiting block 58 is inserted into the rectangular limiting groove 59, and the rectangular limiting block 58 is slidably connected to the rectangular limiting groove 59. During operation, pulling the mounting plate 54 causes the rectangular block 53 to slide inside the rectangular groove 51. After sliding, the rectangular block 53 compresses the spring 52, giving the spring 52 a rebound force. The rebound force of spring 52 facilitates the reset of mounting plate 54. After mounting plate 54 moves, it drives rectangular limiting block 58 to move. The rectangular limiting block 58 moves from inside the rectangular limiting groove 59, which allows mounting plate 54 to disengage from the unwinding roller 3 and allows for disassembly of the unwinding roller 3. During reinstallation, first pull mounting plate 54. After mounting plate 54 is pulled, the rectangular limiting groove 59 inside the roller shaft at the end of unwinding roller 3 aligns with the rectangular limiting block 58. Then, slowly release mounting plate 54 so that mounting plate 54 moves due to the rebound force of spring 52. After mounting plate 54 moves, it drives rectangular limiting block 58 to move and insert into the rectangular limiting groove 59 to limit the installation of unwinding roller 3. Rectangular limiting block 58 is fixedly connected to rotating rod 57. Rotating rod 57 rotates with mounting plate 54 through bearing. Therefore, unwinding roller 3 can rotate between the two mounting plates 54 during unwinding without affecting the unwinding process.

[0033] The two mounting plates 54 are respectively attached to the front and rear surfaces of the vertical plate 2 on opposite sides; during operation, the mounting plates 54 can be attached to and separated from the vertical plate 2.

[0034] Example 2

[0035] Please see Figure 5 As shown in the first embodiment, as another implementation of this utility model, each of the two mounting plates 54 is fixedly connected to a handle 55 on the opposite side; during operation, the handle 55 facilitates the movement of the mounting plates 54.
