Abstract

The invention discloses a variable-angle knitting device of a knitting machine, and relates to the technical field of textile machinery, a shuttle flying mechanism and a beating-up mechanism are integrated on a rack of a weft insertion device, a rotating mechanism is designed at the bottom of the rack of the weft insertion device, and the rotating mechanism is composed of a planetary gear train, an annular guide rail sliding seat, a limiting mechanism and the like. A weft insertion device rack is connected with a rotating mechanism through an annular guide rail sliding seat, a sun gear in a planetary gear train is connected with a motor output shaft, a circular 3D printing piece is connected with the planetary gear train and the weft insertion device rack, and rotation of a motor is accurately controlled through an angle sensor; when the weft insertion device rotates, the shuttle flying mechanism and the beating-up mechanism which are integrated on the weft insertion device rack are driven to rotate by a set angle, and at the moment, the rotating weft insertion device rack is secondarily fixed by the limiting mechanism, so that the stability is improved, and the variable-angle weaving function of the fabric is realized.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a variable angle knitting device of a knitting machine. Background technique [0002] Fiber preform is an important reinforcing phase for the preparation of "lightweight, high-strength" composite materials, and an important material basis for the manufacture of complex flow-through surfaces such as aero-engine blades. The complexity and diversity of application environments require fiber preforms to have a variable-angle structure. . [0003] The knitting machine is a common equipment for weaving fiber preforms. The weaving and beating-up device is an important mechanism in the knitting machine, which plays a key role in the knitting effect of the knitting machine, and completes the weaving and pressing process of the fabric. The warp and weft of the fabric woven by the existing knitting machine are perpendicular to each other (90°) or form other fixed angles, which ca...
