Abstract

Provided is a weft-guiding mechanism for a multi-layer cylindrical weaving machine. The weft-guiding mechanism comprises a weft-guiding fixing board and a weft-guiding shuttle. Multiple groups of transmission devices and multiple shuttle limiting wheels are uniformly arranged along the peripheral direction of the weft-guiding fixing board. The weft-guiding shuttle comprises an arc rack, a yarn-carrying device and a stirring rod. The yarn-carrying device and the stirring rod are arranged on the arc rack. The arc rack is meshed with gears of the transmission devices. The transmission devices comprise fixing seats and stepping motors. Locating holes are arranged in the gears and internally equipped with screws. The gears are fixed in shafts of the stepping motors through screws. Notches are arranged in lower ends of fixing seats and equipped with sensors. The sensors are used for sensing positions of the gears by sensing positions of the screws. Rollers are arranged on the fixing seats. The lower end of the arc rack is equipped with a limiting bottom board. Two sides of the limiting bottom board match the shuttle limiting wheels and the rollers. The weft-guiding shuttle finishes weft-guiding operation by moving along the peripheral direction of the weft-guiding fixing board. The weft-guiding mechanism for the multi-layer cylindrical weaving machine is high in weft-guiding efficiency, good in weaving effect and great in reliability.

Description

technical field [0001] The invention relates to the field of textile equipment, in particular to a weft insertion mechanism of a multi-layer circular loom, which is mainly suitable for improving weft insertion efficiency and weaving effect. Background technique [0002] At present, three-dimensional woven fabric composite materials have been used in various fields due to their excellent mechanical properties and light weight characteristics. The automation of three-dimensional weaving has been realized, but the weaving automation of multi-layer cylindrical woven fabrics in three-dimensional woven fabrics is a technical difficulty, especially in the weft insertion mechanism. Although the existing circular looms can complete weaving with high efficiency, the number of fabric layers to be woven is not many, which cannot meet the requirements of various thicknesses, and the weft insertion mechanism of the circular loom will contact the yarn, causing the yarn to be worn. High pe...
