Problems solved by technology

Although this mechanism can make the carbon fiber yarn spread to a certain extent, because the carbon fiber yarn is relatively slack on the heating and spreading mechanism before entering the heating and spreading mechanism, resulting in the fiber spreading of the heating and spreading mechanism. low quality

Abstract

The invention relates to a fiber stretching guide mechanism. The fiber stretching guide mechanism comprises an installation bracket, wherein a first guide device for guiding yarns to input and a second guide device for guiding yarns to output are arranged on the installation bracket; the first guide device is arranged above the second guide device; and the first guide device and the second guide device are arranged in a staggered manner. According to the fiber stretching guide mechanism, before the yarns enter a heating and fiber stretching mechanism, the yarns are guided to enter the heating and fiber stretching mechanism and are tightened, so that the fiber stretching guide mechanism is helpful for improving the quality and efficiency of the heating and fiber stretching mechanism.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a fiber spreading guide mechanism used in a yarn spreading device. Background technique [0002] Carbon fiber multi-axial warp knitted fabric preforms / LCM process parts have been successfully applied on the new generation of large aircraft Airbus A380, Boeing 787 and Airbus A400M; the rear of Airbus A380 and Boeing 787 aircraft The dome-shaped frame shell of the pressure frame is preformed with 0° / 90° warp-knitted carbon fiber fabric; A380 outer wing spar; A400M cargo door; A380 window frame is made of carbon fiber multiaxial warp-knitted fabric sewing reinforcement ribs. At present, my country has successively built a number of large-scale projects; large aircraft, large-scale offshore wind power generation, lightweight automobile tracks, etc., all require a large amount of carbon fiber multi-axial warp knitted fabrics. This product has a very broad application prospect in our...
