A fuse tension control device

Abstract

The invention provides a fuse tension control device which comprises a melt extrusion machine, a spinning jet and a vertically arranged cooling box body. The spinning jet is arranged at the bottom of the melt extrusion machine; a jet tip of the spinning jet is arranged downwards at the top of the cooling box body; the upper part and the lower part inside the cooling box body are respectively and horizontally provided with an upper pole plate and a lower pole plate; the upper pole plate and the lower pole plate are respectively switched into a cathode and an anode of an electrostatic generator; a ring-shaped rail is coaxially arranged around the spinning jet; the ring-shaped rail is rotationally provided with a laser head for vertically emitting laser downwards; the bottom of the cooling box body is provided with a sensing ring corresponding to the movement track of the laser. In the invention, a fuse is nearly dry when being just formed, so that positive charges are easy to accommodate to generate poly static electricity; the dead weight and the movement inertia of the fuse are offset by an electric field force formed by the upper pole plate and the lower pole plate, so that the tension applied to the fuse is reduced.

Description

technical field [0001] The invention relates to the field of melt spinning equipment, in particular to a fuse tension control device. Background technique [0002] One of the main forming methods of melt spinning chemical fibers, referred to as melt spinning. The main varieties of synthetic fibers such as polyester, nylon and polypropylene are produced by melt spinning. The main features of melt spinning are high winding speed, no need for solvents and precipitants, simple equipment, and short process flow. [0003] In melt spinning, natural or synthetic polymers or inorganic substances are usually made into a spinning melt or solution, and then filtered and metered, extruded from a spinneret (plate) into a liquid stream, and air is used to make it Cool and solidify into tows. The air used to cool the tow is cooled by side blowing, ring blowing and center blowing. At this time, the fiber is called as-spun fiber, and its mechanical properties are very poor. It must go thro...

AI Technical Summary

Problems solved by technology

Due to the poor mechanical properties of the as-spun fiber, it is sensitive to tension, and the length of the cooling box for cooling the tow is very long, which will cause a high pulling force on the upper end of the tow, which is easy to cause the tow broken situation
