Automatic yarn increasing and decreasing yarn carrier for three-dimensional weaving of large stored yarns and using method of automatic yarn increasing and decreasing yarn carrier

Abstract

The invention discloses an automatic yarn increasing and decreasing yarn carrier for three-dimensional weaving of large stored yarns and a using method of the automatic yarn increasing and decreasing yarn carrier. The automatic yarn increasing and decreasing yarn carrier comprises a shell, a top disc, a motor driving device, a supporting plate, yarn storage devices, a yarn increasing and decreasing device and a yarn knotting ring. The top disc and the shell are arranged up and down and are screwed to form a hollow cuboid structure; a supporting plate is horizontally arranged in the shell, and the supporting plate is fixedly connected with the shell; the yarn storage devices are vertically arranged on the upper surface of the supporting plate in a regular triangle shape, the motor driving device is arranged under the yarn storage devices, and the output end of the motor driving device is rotationally connected with the three yarn storage devices and drives the yarn storage devices to send out yarn; a yarn knotting opening is formed in the center of the top disc, and the yarn knotting ring is arranged in the yarn knotting opening; and the yarn increasing and decreasing device is arranged on the periphery of the yarn knotting opening in a regular triangle shape, and yarn is fed into the yarn knotting opening to be woven after being increased and decreased through the yarn increasing and decreasing device. According to the automatic yarn increasing and decreasing yarn carrier for three-dimensional weaving of the large stored yarns, the weaving requirements of the large prefabricated body on the yarn amount and the variable cross section are met, and the weaving stability is improved.

Description

Technical field [0001] The present invention relates to the field of three-dimensional braid, and more particularly to a three-dimensional woven gauze, an automatic increase of gauze, yarn, and its use. Background technique [0002] The three-dimensional braided composite is a material having a good structure, having a weight, high temperature resistance, corrosion, stiffness, etc., three-dimensional knitting is done in the braided machine, and the carrier is the core of the brake Part of the part, therefore is of great significance to the study of the carrier structure. [0003] At present, there is only one coil with wide application in China, and does not have a gauze mechanism and a grease-opening mechanism. When performing a variable cross-section preform, it is usually achieved by changing the number of barrier, not only low efficiency. The braided process is complex, and the integrated performance is not ideal. Therefore, the above problems need to be solved. Inventive co...

Problems solved by technology

[0003] At present, the yarn carrier widely used in China has only one coil, and does not have a yarn increasing mechanism and a yarn reducing mechanism. When weaving variable cross-section prefabricated bodies, it is usually realized by changing the number of yarn carriers, which is not only low in efficiency, but also The weaving process is complicated, and the comprehensive performance of forming is not ideal
