Tension buffering device for chemical fibers

The utility model relates to a chemical fiber tension buffering device, and belongs to the field of chemical fiber processing. Comprising a wire guide nozzle, a wire guide pipe and a fixing assembly, the wire guide nozzle is arranged at one end of the wire guide pipe, the fixing assembly is arranged at the other end of the wire guide pipe, the wire guide pipe is a coil pipe, the wire guide pipe sequentially comprises a lining pipe, a supporting pipe and an outer sleeve from inside to outside, the supporting pipe is formed by winding a metal wire, the lining pipe is attached to the inner wall of the supporting pipe, and the outer sleeve is sleeved with the supporting pipe. The lining pipe is formed by foaming a polyester material, and the outer sleeve is a nylon pipe. The chemical fiber yarn guiding device has the advantages that the guiding-out direction of the chemical fiber yarn is adaptively changed, and the tension change caused by angle mutation is reduced; a shrinkage structure is adopted, and when the
