Description

Technical field:

[0001] The utility model relates to the technical field of carbon fiber needle felt production equipment, in particular to a carbon fiber yarn inlet transition mechanism of a needle punching machine. Background technology:

[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] Among them, the carbon fiber raw yarn is first loosened by the feeding roller, and then pumped into the cotton box by the fan, and then loosened for the second time by the conveying nail curtain through the front and rear nail rollers. The loosened carbon fiber yarn falls evenly on the mesh curtain, enters the pre-needling machine through the mesh curtain to form a pre-needling felt, and is transported to the needle loom again through the conveying and shaping mesh belt on the pre-needling machine for needle punching.

[0004] During the actual installation process, it is necessary to install a transition conveying device between the pre-needling machine and the needling machine to facilitate the reception of the pre-needled felt sent out by the conveyor shaping mesh belt. At present, a belt conveyor is installed on site to send the pre-needled felt between the two roller shafts at the entrance of the needling machine. However, there will be a height deviation between the installed belt conveyor and the conveyor shaping mesh belt and the entrance of the needling machine. It is necessary to manually place an iron plate at the bottom of the belt conveyor frame to adjust the height deviation. Not only is the labor intensity high, but the effect after adjustment is poor, which affects the conveying efficiency of the pre-needled felt. Utility model content:

[0005] The utility model aims to provide a carbon fiber yarn inlet transition mechanism of a needle punching machine which is convenient for adjusting the height difference of a belt conveyor to reduce labor intensity and ensure the conveying efficiency of pre-needled felt.

The seat bearings 7 at both ends of the driven roller 5 are clamped between the two guide rails 3 on the corresponding connecting plates 2, so that the driven roller 5 is installed near the entrance position of the needling machine 1, and the position of the seat bearings 7 can be adjusted up and down by adjusting the position of the seat bearings 7 along the guide rails 3; a support plate 8 is fixed between the lower parts of the two guide rails 3 on each connecting plate 2, and a support screw 9 is passed through the support plate 8, and the top end of the support screw 9 is connected to the corresponding seat bearing 7, and locking nuts 10 are threaded on the support screws 9 on both sides of the support plate 8; after the position of the seat bearing 7 is adjusted, the locking nut 10 and the support screw 9 cooperate to limit the position.

[0018] The top ends of the two bearings with seats 7 on the driven roller 5 are fixed with lifting ears 11, and a lifting motor 12 is fixed on the casing of the needling machine 1 above each connecting plate 2. A lifting roller 13 is fixedly mounted on the output shaft of the lifting motor 12, and a steel wire rope 14 is wound around the lifting roller 13.
