Abstract

The invention belongs to the field of three-dimensional mechanisms, and particularly relates to a continuous parallel traction method and traction device. The traction device comprises a yarn tying mechanism used for tying yarns when a first fabric is woven, a traction fixing mechanism for clamping woven yarns at a weaving section reserved behind the first fabric in the weaving process and pre-pressing unwoven yarns to the horizontal plane, a traction guide mechanism for enabling the yarn tying mechanism and the traction fixing mechanism to move thereon and performing traction in three-dimensional fabric weaving, and a driving mechanism which provides power for the traction guide mechanism. According to the traction device, the traction fixing mechanism and the traction guide and driving mechanisms capable of driving the traction fixing mechanism to reciprocate are arranged, so that the traction is stable and reliable, the operation is easy, continuous weaving of a fabric can be achieved, the consistency of yarn tension is guaranteed, and the preparation efficiency and the consistency of product quality are improved.

Description

technical field [0001] The invention belongs to the field of three-dimensional mechanisms, and in particular relates to a continuous parallel traction method and a traction device. Background technique [0002] At present, the three-dimensional woven fabrics used in aerospace have the characteristics of large thickness and large dimensions. The traditional roller take-up and traction method will cause indentation and wrinkles on the fabric, which will cause irreparable damage to the fabric. At the same time, the friction between the upper and lower surfaces will cause surface friction. The burrs destroy the fabric characteristics, so the traditional traction method is not suitable for the traction of thicker three-dimensional woven fabrics. [0003] The fabric traction device of the flat knitting machine with the application number 200710004060.0, the knitted fabric traction device of the flat knitting machine with the application number 200620003142.4, and the new fabric tr...
