Description

TECHNICAL FIELD

[0001] The utility model relates to the field of fiber weaving machinery more specifically relates to a kind of ceramic fiber three-dimensional fabric's filling warp device. BACKGROUND

[0002] Most of ceramic fiber three-dimensional fabric is woven using 2.5D angle interlocking structure, the fabric formed using 2.5D angle interlocking structure interlaces with each layer of weft yarn following the up-and-down law of binding warp yarn, to obtain three-dimensional fabric with mechanical stability, structural stability;Among them, in the composite material performance test of three-dimensional fabric, the tensile strength of the fiber in straight line state in ceramic fiber three-dimensional fabric is greater than that of the fiber in bending state, and when the ceramic fiber three-dimensional fabric is brought into the filling warp yarn, the mechanical properties of the ceramic fiber three-dimensional fabric are significantly improved.

[0003] However, when weaving this kind of ceramic fiber three-dimensional fabric with filling warp yarn, if using traditional cheese or warp beam to supply yarn, a large number of warp yarns (including filling warp yarn and binding warp yarn) need to be supplied to the loom at the same time, the cheese or warp beam has a long traction distance, and the waste is large, and the cost of ceramic fiber is relatively high, so the formation of ceramic fiber three-dimensional fabric is mainly assisted by equipment and manually woven according to fixed length to reduce the waste of raw materials, but the cost of this kind of three-dimensional fabric is affected by the price and weaving speed of manual work;Moreover, in the weaving process of ceramic fiber three-dimensional fabric, the filling warp yarn is individually transported through each layer positioning roller, such as the layered warp feeding device mentioned in invention patent CN107675335A, each layered positioning roller is arranged between the heald frame and the warp beam, and each layered positioning roller is horizontally arranged between each layer of warp yarn, although each layered positioning roller only individually feeds the filling warp yarn, but the layered positioning roller and the binding warp yarn of each layer also have a 90° orientation, in the weaving of bent interlocking structure, when at least two heddles of each heddle on one of the healds of the corresponding heald frame are lifted upward, the binding warp yarn will collide with the layered positioning roller in the yarn supply route, resulting in a change in the yarn supply distance.

[0004] Further, ceramic fiber is a kind of fiber with high strength, low elasticity and poor ductility, so it is not suitable to apply too much tension during weaving, and it is necessary to add elastic elements to the ceramic fiber one by one, and the stretchability of the elastic elements can avoid the occurrence of fiber fluffing or breaking caused by instantaneous force;When weaving ceramic fiber three-dimensional fabric, according to the size, multiple layers and multiple columns of binding warp yarn and filling warp yarn are designed, and the binding warp yarn and the filling warp yarn are arranged on the hanging beam at the rear end at the same time, using the existing arrangement as mentioned above, it will cause the space between each elastic element to be too crowded, which is not conducive to the stretching and expansion function of the elastic element.

[0005] Therefore, the present application is further researched on the basis, and the present case is generated. Utility Model Content
