Filament bundle conveying paired wheel device

Abstract

The invention discloses a filament bundle conveying paired wheel device. The filament bundle conveying paired wheel device comprises an adhesive pressing wheel. The back of the adhesive pressing wheel is connected with a filament bundle conveying paired wheel device body. The filament bundle conveying paired wheel device body comprises a first paired wheel and a second paired wheel matched with the first paired wheel. The first paired wheel is fixedly arranged behind the adhesive pressing wheel. The second paired wheel is arranged behind the first paired wheel and connected with an air cylinder. An air cylinder push rod on the air cylinder makes the second paired wheel get close to or away from the first paired wheel. The first paired wheel and the second paired wheel both comprise a rotating shaft and steel wire wheel teeth outside the rotating shaft. The steel wire wheel teeth of the first paired wheel and the second paired wheel are semi-open rectangular frame-shaped steel wire wheel bands parallel with the axes of the rotating shafts. According to the technical scheme, the filament bundle conveying paired wheel device is suitable for 0.1 K-200 K filament bundles and capable of meeting the requirement for freely adjusting the filament bundle moving speed from 0 m/min to 1000 m/min; neither high-speed moving conveying nor low-speed moving conveying will cause air-pressure disturbance to the filament bundles, and therefore it is guaranteed that the filament bundles move stably.

Description

technical field [0001] The invention belongs to the field of conveying polyacrylonitrile filament bundles, and more specifically relates to a wheel-aligning device for stably and quickly conveying polyacrylonitrile filament bundles with low K value. Background technique [0002] The K value of the low K value of polyacrylonitrile refers to the number of filaments, 100 represents 0.1K, and the range of low K value is 0.1K~~3K. The smooth transportation of filament bundles is the key in the production of filament bundles. Due to the low K The high-value filament has small mass and light tow, and is very sensitive to the wind pressure and air disturbance around the tow during the conveying process. The negative air pressure generated during high-speed conveying will disturb the tow and cause winding accidents, thus restricting the filament Smooth running of production and capacity development of filaments.
