Twist extrusion method composite rib processing device and twist extrusion preparation method of composite rib
The invention provides a twist extrusion method composite rib processing device and a preparation method, and belongs to the technical field of composite rib processing, the twist extrusion method composite rib processing device comprises a yarn feeding mechanism, a gum dipping mechanism, a yarn guiding and winding mechanism, a twist extrusion pre-forming mechanism and a drying and shaping mechanism which are connected in sequence; the twisting and pre-forming mechanism comprises a support, wire collecting harness clamps clamped at the two ends of the gum dipping wire collecting harness and a twisting driving motor used for rotationally driving the gum dipping wire collecting harness to be twisted, twisted and pre-formed. The yarn guiding and winding mechanism is used for guiding the impregnated yarn to the wire harness collecting clamp holder in a reciprocating and parallel mode after impregnation. According to the twisting-extrusion-method composite rib machining device, composite ribs are formed through the twisting extrusion method, and due to the existence of the inclined twisting extrusion twisting effect, on one hand, friction force and cohesive force between fibers are increased, and certain prestress is given to the fibers; and on the other hand, the inclined twisting can improve the strength homogenization degree of reinforcement fibers, reduce strength weak knots and improve the problem of monofilament breakage, so that the tensile property of a final product is improved.
本发明提供了一种扭挤法复合筋加工装置及制备方法，属于复合筋加工技术领域，包括依次相连的纱线喂入机构、浸胶机构、导纱绕制机构、扭挤预成型机构及烘干定型机构；扭挤预成型机构包括支架、夹持于浸胶集线束两端的集线束夹持器以及用于旋转驱动浸胶集线束扭挤加捻预成型的扭挤驱动电机；导纱绕制机构用于将浸胶后的浸胶纱线往复平行导引至集线束夹持器上。本发明提供的扭挤法复合筋加工装置，利用扭挤法成型复合筋，由于倾斜扭挤加捻作用的存在，一方面增大纤维间的摩擦力和抱合力，赋予纤维一定的预应力；另一方面，倾斜扭挤加捻能够改善增强体纤维的强度均匀化程度，减小强力弱节，改善单丝断裂的问题，从而提高最终产品的拉伸性能。
