Embodiment 1

[0047] Adopt the three-dimensional anti-twisting industrialization device (as figure 1 ), which consists of: carbon fiber guiding system 1, godet wheel group fixing system 2, godet wheel group 3, base system 4, and tension test and alarm system 5. For the convenience of device operation instructions, a three-dimensional direction coordinate is added 19. Carry out a three-dimensional anti-twisting steering of 8 bundles of carbon fibers: the operation process is as follows: ⑴The device is in place: the device is moved from the universal roller 17 to the carbon fiber device before the carbon fiber sizing process or the drying process, or the washing process, or after the high carbon furnace. Place under the tow, by folding the T-square, the axial direction of the guide roller 9 is vertically aligned and fixed at 90° to the running direction of the carbon fiber tow taken. Through the Y-axis movement of the godet wheel set fixing plate 11 and the overfolding of the T-square 7, eac...

Abstract

The invention relates to a slurry-free carbon fiber three-dimensional anti-twist steering industrialization device which is composed of a carbon fiber guide system, a godet wheel set fixing system, a godet wheel set, a base system and an alarm system. The three-dimensional anti-twist steering device can be conveniently grafted to an industrial production line, and damage to the structure and performance of carbon fibers caused by lateral friction, torsioning or twisting behaviors of a traditional separating comb, a guide roller, a guide wheel, a creel and the like in a three-dimensional steering process is completely eradicated; and the ordered steering of the primary pulp-free carbon fiber tows in industrial production can be accurately, stably and simply realized in batches.

Description

technical field [0001] The invention relates to the field of carbon fiber production equipment, in particular to a three-dimensional anti-twisting steering industrial device for pulpless carbon fiber Background technique [0002] Slurry-free carbon fiber is the precursor of finished carbon fiber for various purposes and grades. It is an intermediate product that is processed by electrochemical surface etching, washing and drying processes before the sizing process in the carbon fiber production process and after high-temperature carbonization. Compared with the protection of sizing agent protective film on the outer surface of finished carbon fiber and the protection of flexible groups in the organic molecular chain of pre-oxidized silk and raw silk before the carbonization furnace process, the original pulpless carbon fiber is a highly oriented brittle without any protective measures. The largest graphite sheet skeleton material, its structure is easily affected by guide ro...
