Description

Carbon fiber precursor oiling device Technical Field The utility model belongs to the technical field of carbon fiber production equipment, and particularly relates to a carbon fiber precursor oiling device. Background In the process of industrialization of high-performance polyacrylonitrile carbon fibers, high-quality precursors are a precondition for preparing the high-performance carbon fibers. Oiling is a key process for the preparation of polyacrylonitrile precursors. In the process, the special oiling agent for the precursor is uniformly coated on the surface of the precursor in a certain mode, so that the effect of protecting the fiber is achieved. The uniformity of the oiling content of the precursor plays an important role in controlling the quantity of fiber hairiness and the quantity of broken filaments in the subsequent oxidation and carbonization processes. The main stream of the oil roller type oiling has the problems that the oiling amount is not easy to control, the uniformity is poor and the oiling agent is easy to ripple out. Disclosure of utility model The utility model mainly solves the technical problems existing in the prior art and provides a carbon fiber precursor oiling device. The technical problem is mainly solved by the following technical scheme that the carbon fiber precursor oiling device comprises a frame and a filament bundle, wherein two tangential driving rollers are arranged on one side of the frame, the two driving rollers are respectively arranged at the top and the bottom of one side of the frame, two oiling assemblies are arranged between the two driving rollers which are arranged up and down, each oiling assembly comprises an oil groove, mounting plates on two sides and an oiling roller, the mounting plates are arranged on two sides of the oil groove, a working oil groove and an overflow oil groove are respectively arranged in the oil groove, the oiling rollers are arranged above the working oil groove, seat bearings are respectively arranged on the left side and the right side of the oiling roller, the seat bearings are connected with the mounting plates, a distribution plate is arranged in the overflow oil groove, and a plurality of slots are formed in the distribution plate. Preferably, the tow forms an angle of about 7 ° with a perpendicular to the tangent point of the upper oiling assembly, and the tow forms an angle of about 4 ° with a perpendicular to the tangent point of the upper oiling assembly. Preferably, a bottom frame is arranged on one side of the bottom of the frame, an oil collecting hopper is arranged at the top of the bottom frame, and the oil collecting hopper is positioned below the tows. Preferably, mounting frames are arranged at the bottoms of two sides of the distribution plate, limiting plates are arranged above two sides of the oil groove, the limiting plates are arranged above the mounting frames, adjusting screws are connected between the mounting frames and the limiting plates, and the adjusting screws penetrate through the distribution plate.
