Problems solved by technology

[0008] Fourth, the jaw material needs to have good resilience, that is, its elasticity is better, but if the elasticity is too large, the optical fiber filament is easy to stick to it, and the elasticity is too small to make the drawing process slip;
[0010] Rubber is a kind of elastic and insulating material made after processing. It is a highly elastic polymer material. It is widely used in various aspects of industry and life. After using rubber, the surface of optical fibers is often damaged and damaged. scratches, and the diameter accuracy and ellipticity of optical fibers cannot be kept stable, which seriously restricts the performance improvement of optical fiber image transmission components; natural rubber has high elasticity at room temperature, but its high temperature resistance is poor, it is easy to age, and Poor abrasiveness, easy to produce friction particles, short service life, and severe chip shedding during use; existing polyurethane materials on the market have the advantages of wear resistance and chemical corrosion resistance, but poor heat resistance, and the general use temperature does not exceed 80 ℃; materials such as nitrile rubber have good wear resistance and heat resistance, but due to poor aging resistance, severe wear, and short service life, they are not suitable for the process of pulling wires; while silicone rubber materials have superior rebound performance , but the wear resistance is poor, and its surface is too viscous, which is easy to absorb dust, which will affect the cleaning of the surface of the optical fiber during the drawing process and even cause adhesion with the optical fiber
[0011] Existing gripper materials for optical fiber filaments cannot meet the performance requirements of high-performance optical fiber image transmission components
