Description

Technical Field

[0001] The utility model relates to the technical field of spinning devices, in particular to a fiber-forming polymer spinning device. Background Art

[0002] Fiber-forming polymers are synthetic high-molecular polymers that can be made into fibers. They must not only be able to form fibers but also completely dissolve in a suitable solvent to form a viscous concentrated solution, or melt at elevated temperatures to convert into a viscous flow without decomposing, allowing for solution spinning or melt spinning. Solution spinning involves extruding a quantitative amount of a concentrated polymer solution from a spinneret, where the solution stream solidifies into fibers through a coagulation bath, hot air, or hot inert gas. During the spinning process, the melt must be uniform in particle size and temperature, and must be free of air to prevent it from affecting the quality of the tow fibers.

[0003] Most existing fiber-forming polymer spinning devices lack a defoaming function to reduce or eliminate the air mixed in the melt, resulting in low quality of the filament fibers. Therefore, a fiber-forming polymer spinning device is proposed to solve the above problems. Utility Model Content

[0011] Furthermore, a strip-shaped opening is provided on the shaft near the steel wire strip, and the steel wire strip passes through the inner side of the strip-shaped opening.
