Cylindrical three-dimensional weaving platform

Abstract

The invention provides a cylindrical three-dimensional weaving platform which comprises a central shaft and n stripy units, wherein the n stripy units are annularly distributed around the central shaft; n is an even number; each stripy unit comprises a bottom plate strip; the length direction of each bottom plate strip is parallel to the direction of the central shaft; each bottom plate strip comprises two opposite surfaces; one surface facing to the central shaft, of each bottom plate is an inner surface; one row of m inner yarn carrying discs are arranged on one side of the inner surface of each bottom plate strip in the length direction; m is a natural number; the inner yarn carrying discs on the n stripy units form a cylindrical weaving platform; m circles and n rows of inner yarn carrying disc arrays are arranged on the cylindrical weaving platform; each inner yarn carrying disc is in transmission connection by using an inner shaft which is pivoted with each bottom plate strip; the inner shafts are connected with one same power source or different power sources, so that the inner yarn carrying disc arrays can relatively rotate at a preset speed in a preset direction. By adopting the weaving machine provided by the invention, the weaving platform can be very conveniently expanded.

Description

technical field [0001] The invention relates to a three-dimensional braiding machine, in particular to a cylindrical braiding platform of a cylindrical three-dimensional braiding machine. Background technique [0002] Three-dimensional weaving technology is an important technology for preparing composite materials, especially advanced fiber-reinforced composite material preforms. Applications. [0003] At present, the three-dimensional knitting machines in the world are divided into four-step method, two-step method and rotary method from the weaving method (the former two are also called vertical and horizontal stepping methods, and the latter rotary method is referred to the applicant's Chinese invention patent: rotary knitting machine, application number is 200810226422.5), wherein the rotation method is relatively high in production efficiency due to continuous operation. [0004] According to the shape of the platform, the current three-dimensional knitting machine ca...

AI Technical Summary

Problems solved by technology

[0005] In the three-dimensional knitting machine technology of the circular (disc) shaped platform, the applicant has also encountered a bottleneck: on the circular (disc) shaped platform with a plurality of circular tracks, the more the carrying disc on the circular track of the outer edge The larger the diameter, the larger the number of circular tracks, resulting in a rapid increase in the area of ​​the equipment table, and the rapid increase in the amount of yarn returned during the movement of the yarn carrier from the inner ring to the outer ring, so the number of circular tracks can only be limited In a limited range, this type of braiding machine in the world generally only has 5-6 rings of circular track

[0006] In short, there is currently no cylindrical three-dimensional weaving platform that can perform continuous weaving by rotary method, and can reduce the footprint while ensuring production efficiency
