[0002] Carbon fiber needle punched felt is the skeleton of composite materials such as carbon / carbon composite materials and carbon / ceramic composite materials. In the production process of carbon fiber needle punched felt, the asphalt raw material is heated and spun to obtain asphalt precursor, which is then transported to the pre-oxidation furnace and carbonization furnace in turn to make asphalt-based general-grade carbon fiber precursor, and finally, after subsequent opening, pre-felt and needle punching treatment, carbon fiber needle punched felt is obtained.

[0003] The carbon fiber raw yarn is fully opened by the opening machine and then sent to the carding machine. The curled fiber balls are combed into straight single fiber states by the carding machine, and the fiber web output by the carding machine is stacked into a multi-layer fiber web of a predetermined thickness for subsequent pre-needling.

[0004] Among them, the loosened carbon fiber filaments are sent to the entrance of the carding machine through a transition belt conveyor, and are sent into the carding machine through the engagement of the rollers at the entrance of the carding machine; however, in actual production, since the carbon fiber filaments are relatively smooth, there is a phenomenon of carbon fiber filament accumulation at the rollers at the entrance of the carding machine, the feeding efficiency is poor, and there is a phenomenon that the carbon fiber filaments slip from both sides of the transition belt conveyor to the ground, causing waste.
