Description

Technical Field

[0001] The utility model relates to the technical field of hair fiber production equipment, in particular to a PVC hair fiber melt spinning mechanism. Background Art

[0002] A wig is an artificial product, usually made of artificial fibers or real human hair. In the existing production of PVC hair fibers, it is generally manufactured through a PVC hair fiber melt spinning mechanism.

[0003] In the process of fiber melt spinning, first, the polymer raw material is fed into a screw extruder, sent to the heating zone by a rotating screw, extruded and melted, and then sent forward to a metering pump. The metering pump controls and ensures the stable flow of the polymer melt into the spinning box. In the box, the melt is filtered and pressed into a porous spinneret to eject a melt stream, and then quickly solidified into a solidified filament fiber by the cold air blown out by a temperature-adjusting air box.

[0004] The melt conveying system is the starting point of the entire melt spinning machine. At present, generally, PVC pellet raw materials are manually poured into the feeding port of the extruder, and the amount of PVC pellet raw materials added cannot be accurately controlled according to needs, which easily causes waste of raw materials. Moreover, it is time-consuming and laborious to lift the raw materials and pour them into the feeding port, increasing the labor intensity of the staff. Therefore, a PVC hair fiber melt spinning mechanism is needed to solve the above problems. Content of the Utility Model
