Dynamic spinning melt mixer

Abstract

The invention discloses a dynamic spinning melt mixer which comprises a fixing shaft and a mixing sleeve. The mixing shaft is rotatably arranged in the mixing sleeve, at least one mixing section for melt mixing is correspondingly arranged on the mixing shaft and the mixing sleeve, spiral convex edges for melt conveying are arranged on the portions on two sides of the mixing section, of the mixing shaft, the spiral convex edges located at the front section of the mixing section in the advancing direction of a melt material are input spiral convex edges, the spiral convex edges located at the rear section of the mixing section are output spiral convex edges, and communicating notches are formed in the input spiral convex edges and enable the material conveying spaces on two sides of the input spiral convex edges to be communicated. The dynamic spinning melt mixer is simple in structure and easy to achieve. In addition, the dynamic spinning melt mixer has a pressure relief function, accordingly and well controls the temperature rise of a belt in the mixing process, meanwhile plays a mixing assisting function and improves the mixing effect.

Description

technical field [0001] The invention relates to a textile equipment, in particular to a textile melt dynamic mixer. Background technique [0002] Melt spinning, referred to as melt spinning. It is a chemical fiber spinning method in which the polymer is heated and melted, extruded through the spinneret hole, cooled and solidified in the air to form fibers. Polymers used for melt spinning must be able to melt into a viscous fluid state without significant decomposition. Polyester, polyamide and polypropylene fibers can all be produced by melt spinning. The melt spinning process mainly includes: the fiber-forming polymer is heated and melted in the screw extruder, the melt is extruded from the spinneret hole through a metering pump to form a thin stream, the melt stream is cooled and solidified, and the filaments are oiled and coiled. Winding, stretched and thinned to obtain fibers. In the melt spinning process, the uniformity of the melt is crucial to the quality of the f...

AI Technical Summary

Problems solved by technology

However, the mixer with this structure has a problem of large temperature rise in specific applications, because when the melt is sent into the mixing section through the spiral rib, a relatively high pressure can be established, and the greater the pressure, the higher the temperature of the melt will be. bigger

And the temperature is too high will greatly affect the quality and performance of the melt
