Problems solved by technology

[0005] The purpose of the present invention is to address some of the deficiencies of the prior art. The present invention discloses a single-layer graphene multifunctional composite fiber melt spinning equipment, which transports uniform and non-fluctuating cooling air to the cooling unit through the delivery unit. The cooling unit is blown and cooled evenly along the conveying direction of the composite fiber, so that the deflection of the composite fiber under the action of the wind is less, and the impact of the swing of the composite fiber and the edge of the forming hole of the spinneret affecting the molding of the composite fiber is reduced, and the breakage of the composite fiber is reduced or avoided. problems, ensuring the production quality of composite fibers; at the same time, through the rotation of the rotating blade in the direction of composite fiber feeding, the burrs such as wire drawing on the surface of composite fibers can be removed, and the problem of low production quality of composite fibers can be further solved.
