A yarn-hanging device and yarn-hanging method for fiber-wound composite materials adapted to multi-specification tubes

Abstract

The invention discloses a filament wound composite yarn hanging device and method adapting to pipes of various specifications. The device comprises a plurality of cylindrical yarn teeth and a plurality of prismatic yarn teeth, wherein bases are arranged at the bottoms of the cylindrical yarn teeth and the bottoms of the prismatic yarn teeth, the adjacent cylindrical yarn teeth are hinged through the bases in an end-to-end mode, the cylindrical yarn teeth and the prismatic yarn teeth are hinged through the bases in an end-to-end mode, the ends of the adjacent bases are hinged through rivets, a hinged loop chain is formed and wound on the outer wall of a mold pipe in a sleeving mode, each face of the outer wall of the mold pipe corresponds to at least one prismatic yarn tooth, and the same sides of the cylindrical yarn teeth and the prismatic yarn teeth are arranged outwards. The yarn hanging device is simple in structure, easy to manufacture, applicable to molds of different sizes and different modes, and high in practicability. The method dismounts the yarn hanging device before curing is completed, so that the adverse effect caused by yarn hanging is reduced to be the lowest, a transition section of the filament winding end portion is omitted, the production efficiency is greatly improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of textile equipment, in particular to a yarn-hanging device and a yarn-hanging method for fiber-wound composite materials adapted to multi-standard tubes. Background technique [0002] During the continuous winding process of the composite material rectangular tube, there is a looping process at the end. The realization of this process requires a transitional change in the fiber winding angle, and the length of the transition section is longer for the winding mode with a smaller angle. However, in actual production, many manufacturers cut off the transition section after the composite product is solidified, which not only wastes materials, but also reduces production efficiency. [0003] In the small-angle winding process of composite rectangular tube, there will be a large transition area due to the winding angle transition method at the end. For the winding method below 10°, the transition area is very l...

Problems solved by technology

However, in actual production, many manufacturers cut off the transition section after the composite product is cured, which not only wastes materials, but also reduces production efficiency.

[0003] In the small-angle winding process of composite rectangular tube, there will be a large transition area due to the winding angle transition method at the end. For the winding method below 10°, the transition area is very long, which is difficult to achieve in actual winding.

Ordinary yarn hanging devices are fixed in size and are only suitable for composite products of a single size. The mold after changing the size and the fiber winding after changing the yarn width can only be reprocessed, and there is no universality of application.

And when the yarn slides on the yarn teeth, it is easy to wear and tear, and in severe cases, the yarn will break
