Rinsing and hot drawing device for fibre tow spinning

Abstract

The invention relates to a rinsing and hot drawing device for fibre tow spinning. The device comprises a box body, a heat source supply device arranged outside the box body, a plurality of transmission devices which are fixed on the box body and arranged in the box body and a waste heat collecting device arranged on the top of the box body, wherein each transmission device contains a transmission shaft and a transmission roller sleeved on the transmission shaft; the transmission roller is prepared from a porous material; the transmission shaft is of a hollow structure; a plurality of liquid outlet holes are uniformly distributed on the side wall of the transmission shaft; and the heat source supply device is communicated with a plurality of transmission shafts respectively. By adopting the rinsing and hot drawing device, the technical problems that the existing rinsing and hot drawing device for fibre tow spinning damages the fibre tow and has low drawing efficiency can be solved. The invention provides the rinsing and hot drawing device for fibre tow spinning which can realize that the high strength of the carbon fibre precursor tow can be ensured and the filaments can not be broken easily under a large drafting force.

Description

technical field [0001] The invention relates to the technical field of carbon fiber precursor textile equipment, in particular to a water washing and hot drawing device for fiber tow spinning. Background technique [0002] In the manufacturing process of carbon fiber precursor tow, hot water drafting device is an important equipment in the production of precursor, which directly affects the production of high-performance carbon fiber. Common spinning water washing and hot drawing are all adopted water bath method or spraying method to ensure that the carbon fiber precursor tow is drawn under high temperature water environment. [0003] The existing fiber tow spinning water washing and hot drafting device causes the fiber tow to be easily damaged during the drafting process due to the transfer roller, and it is easy to produce fluff and broken filaments, and the drafting efficiency is not high. Contents of the invention [0004] In order to solve the technical problems tha...
