Loom for conical and cylindrical shell three-dimensional fabric

Abstract

The invention discloses a loom for conical and cylindrical shell three-dimensional fabric. The loom comprises a main rack and is characterized by further comprising a mandrel, a let-off mechanism, an opening mechanism, a weft insertion mechanism and a beating-up mechanism, wherein the mandrel is installed in the main rack, the let-off mechanism, the opening mechanism and the weft insertion mechanism are arranged on the periphery of the mandrel, and the beating-up mechanism is arranged on the mandrel; the opening mechanism enables warp to form an opening automatically, the weft insertion mechanism completes circumferential weft insertion, then weft is beaten up through the beating-up mechanism, and the steps are repeated till weaving is completed. The loom for the conical and cylindrical shell three-dimensional fabric is simple in structure, a manual weaving mode is changed into an automatic manufacturing mode, labor cost is greatly lowered, working efficiency is improved, and the technical problems that yarn counts of all parts of the fabric are not uniform, the profile size of the fabric is poor in accuracy, and the overall mechanical property of the fabric is weak are effectively solved.

Description

technical field [0001] The invention relates to the field of textile technology, in particular to a three-dimensional fabric loom with conical and cylindrical shells. Background technique [0002] The three-dimensional fabric of the conical and cylindrical shells can be made into a composite material shell after being compounded with some thermosetting resins. Compared with the traditional metal shell, the composite material shell is greatly reduced in weight, and its various properties are also improved. It can meet the actual production requirements, even better than metal parts, and can be used in civil and military fields. The three-dimensional fabric of the conical and cylindrical shell usually has a top at one end, and the preformed shell fabric is formed by regularly increasing or decreasing the warp yarn at the edge, and then the weft yarn moves along the mandrel for one week to complete the weft insertion, and finally weaves into a conical fabric. , Cylindrical she...
