Problems solved by technology

[0003] Because the chemical fibers produced by melt spinning have the advantages of bright colors, soft texture, drape, smooth and comfortable, they are widely used, but the chemical fibers produced by melt spinning are constant due to the pressure of the melt extrusion device. The diameter of the fuse is basically the same, resulting in a smooth surface of the fuse, and it is not easy to cohere when it is twisted into a yarn

Abstract

The invention provides a diameter-variable fiber melting structure comprising a vertical tubular shell. A rotary shaft driven by a driver is disposed axially in the tubular shell. A disc melt extruder is disposed on the rotary shaft. The periphery of the melt extruder is evenly provided with projecting telescopic chambers. Each telescopic chamber is provided with a nozzle which telescopes radially along the melt extruder. An elastic belt is connected to the root of each nozzle. The other end of every elastic belt is fixed in the center of the melt extruder. A reel structure for reeling melt fibers sprayed from the nozzles is further disposed in the tubular shell. By controlling the rotation speed of the melt extruder, the nozzles extend out in different lengths under the centrifugal action of the nozzles and the inner pressure of the nozzles also varies; the longer the nozzles extend out, the higher the inner pressure of the nozzles, namely, the larger the diameter of the melt fibers sprayed from the nozzles, and accordingly, the diameter-variable melt fibers are produced.

Description

technical field [0001] The invention relates to the field of melt spinning equipment, in particular, a fuse structure for manufacturing variable-diameter fuses. 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. Fiber-forming polymers that have a melting point below their decomposition temperature and can be melted to form a thermally stable melt can be formed by this method. The preparation of chemical fibers is usually made of natural or synthetic polymers or inorganic substances into a spinning melt or solution, then filtered, metered, extruded from a spinneret (plate) into a liquid stream, and then Solidified into fibers. The fiber at this time ...
