Multi-filament bundle equally-spaced filament-discharge compensation device of composite material filament paving head

Abstract

The invention discloses a multi-filament bundle equally-spaced filament-discharge compensation device of a composite material filament paving head. The device comprises a guiding bundle combiner, an equally-spaced compensation cutter, multiple guiding cutting cutter heads, fiber filament bundles and a paving roller. The equally-spaced compensation cutter is provided with the multiple guiding cutting cutter heads and is used for compensation of difference of filament bundle channel paths of the guiding bundle combiner. The guiding bundle combiner is fixedly connected to the equally-spaced compensation cutter seat and is used for combining fiber filament bundles subjected to path compensation from different directions to form a uniformly-arranged fiber cloth and transmitting the uniformly-arranged fiber cloth into the paving roller for fiber filament bundle bi-directional paving arrangement. The paving roller is arranged oppositely to the guiding bundle combiner in a positional relationship fixation way and is used for paving and compacting the fiber cloth transmitted by the guiding bundle combiner on the surface of a mold so that a compact fiber paved layer is formed. The device realizes equally-spaced filament-discharge arrangement, provides and paves fibers with required length according to requirements, improves fiber paved product quality, reduces filament bundle waste and reduces control system complexity.

Description

technical field [0001] The invention relates to the technical field of automatic laying and forming of composite materials, in particular to a multi-bundle equidistant silk output compensation device of a composite material laying head. The invention is mainly used in the laying and forming process of multi-bundle composite fiber tow materials , when laying the composite material, solve the phenomenon that the fiber tows of the composite material pass through the unequal-distance guiding bundle section of the guide combiner, and the lengths of the filaments entering the laying roller are not equal. Background technique [0002] Composite materials have the advantages of high specific strength, high specific modulus, fatigue resistance, good vibration damping, and good manufacturability. These advantages are of great value to the performance of aircraft, and have been widely used in the aerospace industry. At the same time, in other industries, such as sports equipment, ships...

Problems solved by technology

[0006] In order to solve the above problems, the present invention develops a supplementary device for multi-filament laying and equidistant filament discharge. Through structural improvement, it compensates for the length difference of different paths leading to the beam combiner, and eliminates the problem that each filament bundle passes through different paths during laying. The phenomenon of inconsistency in the length of filaments, realizes the precise shape and position layup control of multi-filament bundle fibers when laying complex shapes and positions
