Multilayered fabric weaving machine

Abstract

The invention discloses a multilayered fabric weaving machine. The multilayered fabric weaving machine comprising a let-off mechanism, a shedding mechanism, a weft insertion mechanism, a beating-up mechanism, and a rolling mechanism, wherein the shedding mechanism comprises a shedding frame; a plurality of shedding cylinders, a plurality of upper connecting plates, an upper amplifying plate, an upper mesh plate, a harness wire, a lower mesh plate, a lower amplifying plate, a plurality of lower connecting plates are arranged on the shedding frame; every shedding cylinder is connected with the corresponding upper connecting plates; the lower end of every lower connecting plate is provided with a returning spring; and the lower end of the returning spring is fixed at the bottom end of the shedding frame. After being connected with harness cords respectively, the upper end and lower end of every harness wire are respectively crossed through the upper mesh plate and lower mesh plate, the upper amplifying plate and the lower amplifying plate through the harness cords, then every group of harness cords are connected with the corresponding connecting plate; through the direct connection between the harness cords and the harness wires, the space limit caused by a heald frame in the traditional weaving machine is avoided; thereby weaving of the multilayered fabric is realized under a certain opening.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a multi-layer fabric loom. Background technique [0002] Multi-layer woven fabric means that the yarns are interspersed with each other in space, and interweaved into a certain geometric shape to form a spatial network. , Excellent mechanical properties and many other advantages, it has been widely used in aerospace, automobile, ship and many other fields. However, the production of multi-layer fabrics is technically difficult, costly, and low-yield, and sometimes cannot meet the needs of the structure well. Therefore, how to weave integral woven fabrics with multi-layer interwoven structures has become one of the focus of research in the field of composite materials in recent years. one. [0003] Existing multi-layer looms generally drive the heald frame to move up and down through a cam mechanism or a crank-link mechanism. In the actual process, there are many disadvantage...

However, the production of multi-layer fabrics is technically difficult, costly, and low-yield, and sometimes cannot meet the needs of the structure well. Therefore, how to weave integral woven fabrics with multi-layer interwoven structures has become one of the focus of research in the field of composite materials in recent years. one

[0003] Existing multi-layer looms generally drive the heald frame to move up and down through a cam mechanism or a crank-link mechanism. In the actual process, there are many disadvantages, such as: the shape of the cam is complex, and the heald frame movement is likely to be unstable during the heald lifting process. At the same time, because the size of the opening is limited by the size of the cam, crank and traditional heald frames, the number of heald frames is reduced under a certain opening, which affects the number of layers of the fabric. Only simple fabrics can be produced, and the quality of the fabric is also low. hard to guarantee

[0004] Existing multi-layer woven fabrics are generally transformed by some second-hand looms, mostly in manual or semi-mechanical state, so the quality of the fabric is difficult to guarantee
