An automatic increasing and decreasing yarn carrier for three-dimensional weaving with large yarn storage and its use method

Abstract

The invention discloses an automatic increasing and decreasing yarn carrier for three-dimensional weaving with large yarn storage and a method of using it. It includes a shell, a top plate, a motor drive device, a support plate, a yarn storage device, a yarn increasing and decreasing device and a yarn knotting ring. ; The top plate and the shell are arranged up and down, and are screwed together to form a hollow rectangular parallelepiped structure; a support plate is provided horizontally inside the shell, and the support plate is fixedly connected to the shell; a yarn storage device is vertically provided in an equilateral triangle shape on the upper surface of the support plate, and There is a motor drive device directly below it. The output ends of the motor drive device are respectively connected with three yarn storage devices to rotate and drive the yarn storage device to send out yarn. There is a yarn knotting port in the center of the top plate, and the yarn knotting port is located in the center of the top plate. There is a yarn knotting ring inside the mouth; a yarn increasing and decreasing device is arranged in an equilateral triangle shape around the yarn knotting mouth, and the yarn is added and subtracted through the yarn increasing and decreasing device, and then the yarn is fed into the yarn knotting mouth for weaving. The invention realizes the weaving requirements for large prefabricated bodies in terms of yarn quantity and variable cross-section, and improves the stability of weaving.

Description

technical field [0001] The invention relates to the technical field of three-dimensional weaving, in particular to an automatic increase and decrease yarn carrier for large yarn storage in three-dimensional weaving and a use method thereof. Background technique [0002] The three-dimensional weaving composite material is a material with good structural performance, which has the advantages of light weight, high temperature resistance, corrosion resistance, and good rigidity. The three-dimensional weaving is completed in the weaving machine, and the yarn carrier is the core of the weaving machine. Therefore, it is of great significance to study the structure of the yarn carrier. [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 ...

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
