Filament collecting device for carbon fiber winding forming and carbon fiber winding forming method

Abstract

The invention provides a wire collecting device for carbon fiber winding forming and a carbon fiber winding forming method. The technical problem that in the prior art, the carbon fiber winding effect is not good is solved. According to the filament collecting device for winding and forming of the carbon fibers and the winding and forming method of the carbon fibers, the tension sensor is used for detecting the real-time detection tension of the filament bundle in the winding process in real time; due to the fact that the coiling diameter of the silk coil is larger and larger in the process that the tow is coiled into the silk coil, the tension of the silk coil is linearly and proportionally reduced along with the increase of the coiling diameter of the silk coil, and the silk coil can be formed excellently. Therefore, the tension of the tows can be regulated and controlled, and the tension is reduced, so that the tension of the tows is reduced in a linear proportion, and a wire coil can be formed excellently. When the winding parameters are controlled, the winding parameters are regulated and controlled from the principle, the winding parameters can be regulated and controlled in real time, in addition, different winding parameters can be matched according to different carbon fiber tows, and the winding formability of the carbon fiber tows is improved.

Description

technical field [0001] The invention relates to the technical field of carbon fibers, in particular to a winding device for carbon fiber winding and molding and a carbon fiber winding and molding method. Background technique [0002] Polyacrylonitrile-based carbon fiber precursors are pre-oxidized, carbonized and post-processed to make polyacrylonitrile-based carbon fiber carbon fibers (hereinafter referred to as carbon fibers). , for the subsequent production of carbon fiber products. Subsequent use, transportation, storage and other requirements for the winding and forming of the wire coil are as follows: the coil is well formed, the surface (cylinder surface) and the end face of the wire coil are flat, the tension is appropriate, and the capacity of the wire coil is high (winding density is greater than or equal to 1.0g / cm3 ), no overlapping wires, smooth unwinding. [0003] However, in the prior art, it can be achieved by controlling the winding parameters, but the car...
