Description

Technical Field

[0001] The utility model relates to a U-shaped groove wire guiding roller for improving the uniform distribution of carbon fiber tows, belonging to the technical field of carbon fiber wire guiding rollers. Background Art

[0002] Carbon fiber has the characteristics of high strength, small coefficient of thermal expansion, and good damping performance. When carbonizing and processing raw tows of different specifications, carbon fibers will stick together in some processing processes. It is necessary to use a wire splitting device to separate the carbon fibers, and the wire guiding roller is used to achieve the wire splitting operation due to its small impact on the production line and stable operation.

[0003] The existing wire guiding rollers can effectively solve the technical drawbacks that affect the quality of the final product, such as the deviation of tows and the contact and adhesion of tows during the processing of carbon fibers. However, there are still many defects in the wire guiding rollers with similar structures during actual use, such as:

[0004] 1. When adjusting the wire path of the tows, it is not convenient to adjust the whole roller;

[0005] 2. When changing from small tows to large tows, the wire guiding roller suitable for small tows will change the shape of large tows. Different specifications of tows are not suitable for the same type of wire splitting device, resulting in poor compatibility and reducing the convenience of using the device;

[0006] 3. Since the device cannot be freely disassembled and assembled during operation, it is not convenient for production personnel to adjust and replace, increasing the difficulty of the operation.

[0007] In summary, the existing technology is obviously inconvenient and defective in actual use, so it is necessary to improve. Content of the Utility Model

[0008] Aiming at the deficiencies in the background art, the utility model provides a U-shaped groove wire guiding roller for improving the uniform distribution of carbon fiber tows, which can facilitate the adjustment of the wire path and adapt to different specifications of tows by replacing different segmented sleeves, with good compatibility.

[0014] Further, a locking nut section is also provided between the segmented sleeve section and the bushing section of the support mandrel. The locking nut section is provided with an external thread, and a locking nut is threadedly installed on the locking nut section. The locking nut abuts against the end of the segmented sleeve.
