Abstract

The invention discloses a multi-wire-harness fiber filament spreading tension control device used in a high-pressure hydrogen cylinder production line. A carbon fiber filament spreading tension control device and a glass fiber filament spreading tension control device are arranged on a filament frame up and down; the carbon fiber filament spreading tension control device consists of a plurality ofcarbon fiber filament spreading tension control mechanisms; the glass fiber filament spreading tension control device is composed of a plurality of glass fiber filament spreading tension control mechanisms; a branching plate with a first threading through hole group and a second threading through hole group is fixedly arranged at the rear end of the filament frame; the first threading through hole group is composed of a plurality of first threading through holes; the first threading through holes correspond to the carbon fiber filament spreading tension control mechanisms in number and are matched with the carbon fiber filament spreading tension control mechanisms in a one-to-one mode; the second threading through hole group is composed of a plurality of second threading through holes; and the second threading through holes correspond to the glass fiber filament spreading tension control mechanisms in number and are matched with the glass fiber filament spreading tension control mechanisms in a one-to-one mode. By adopting the device, the tension of fiber tows is stable and controllable in the filament spreading process, and fluffing, knotting and other phenomena are not likely tohappen.

Description

technical field [0001] The invention relates to the field of high-pressure hydrogen bottle manufacturing, in particular to a multi-bundle fiber spinning tension control device used in a high-pressure hydrogen bottle production line. Background technique [0002] Carbon fiber is an inorganic fiber formed by cracking and carbonizing organic fibers in a high-temperature environment to form a carbon main chain structure. It is an inorganic fiber with a carbon content higher than 90%. It has high strength (strength specific density), high specific stiffness (modulus ratio Density) performance, corrosion resistance, fatigue resistance and other characteristics, so it is widely used in high-pressure hydrogen bottles. [0003] The fiber layer in the high-pressure hydrogen bottle is composed of carbon fiber layer and glass fiber layer. The carbon fiber layer is composed of carbon fiber tow by wet winding. The glass fiber layer is composed of glass fiber tow by wet winding and wrapped...

AI Technical Summary

Problems solved by technology

[0005] 1. The tension of carbon fiber tow is unstable and uneven, which may lead to inconsistent dipping amount in the later stage and affect the quality of carbon fiber winding;

[0006] 2. The surface of carbon fiber tow is easy to rub and fluff, which reduces the strength of carbon fiber and increases the dispersion coefficient, resulting in insufficient subsequent dipping, which leads to the formation of voids in the carbon fiber layer and affects the mechanical properties of carbon fiber;

[0007] 3. Multiple carbon fiber tows are easily knotted when winding together, resulting in interruption of winding
