Thread spraying structure

Abstract

The present invention belongs to the field of spinning technology, and is especially one kind of spinning mechanism for spinning various kinds of artificial fiber. The spinning mechanism includes spinning plate seat, spinning plate, spinning cap seat cavity on the spinning plate and spinning cap with fine spinning orifices, and features that it includes also one rotating unit, which is rotated with one drive unit and is stretched into spinning cap seat cavity, and one spinning cap seat, which is configured onto the rotating unit and has spinning cap inside it. One of the advantages is that the rotating spinning cap seat and spinning cap makes the spun tow rotation twisted and makes broken tow taken out to avoid winding on the roller; and the other is that the spun filaments twisted separately without mutual tangling, being favorable to tow separation.

Description

technical field [0001] The invention belongs to the technical field of spinning application, and more specifically relates to a spinning mechanism used for spinning artificial fibers such as acrylic, nylon, polyester, viscose, and spandex. Background technique [0002] Man-made fibers, such as acrylic, nylon, polyester, viscose, spandex, etc., although the production process is not the same, generally include spinning, forming, drawing, oiling, post-processing and other processes. The spinning process is to extrude the spinning stock solution from the micropores on the spinner cap of the spinning mechanism, that is, the spinneret hole, so as to form primary fibers. This process is the first step in the entire spinning process, and it is also the current industry Recognized as the most important step. Since the spinneret will inevitably damage the spinneret hole during use, resulting in broken filaments during the spinning process; in addition, the presence of air bubbles, i...

Problems solved by technology

It can be seen from the above structure that because the spinneret 3 is fixed on the spinneret seat cavity 5, the spinneret 3 is static, and the filament bundles ejected during the spinning process do not have cohesive force, so broken filaments can't be carried away

Especially in the filament production process, because the number of filaments in the tow is relatively small, so the cohesion is very poor, and the broken filaments can hardly be entrained away, and the floating filaments will be wrapped around the rollers to form entanglements. rolls, which affect the smooth operation of the production line, resulting in low output and unguaranteed quality; in addition, the winding rolls need to be handled manually by the operator, which greatly increases the probability of safety accidents. In fact, safety accidents in the chemical fiber production industry mainly occur in the processing of winding roll in process

[0005] The defect that the spinneret mechanism in the prior art exposes during the spinneret process can be more amplified by the figure 2 To reveal that this figure is an example of only one spinneret 3 being set on one spinneret 1, obviously, spraying from thousands of very fine spinneret holes 4 on the spinneret 3 There is no cohesive force between the tens of thousands of primary fibers S produced. When a broken filament P is generated, it cannot be carried away by other filaments and will be wound on the roller to form a roll

[0006] can also be made by image 3 It is revealed that the tens to hundreds of primary fibers (filaments) S ejected from the tens to hundreds of tiny spinneret holes 4 on the spinneret 3 are less cohesive due to the small tow, resulting in When the filament P is broken, it cannot be entrained away. In addition to the above-mentioned disadvantages of wrapping the roll, it will also interact with the primary fiber S ejected from the spinneret hole 4 of the different or adjacent spinneret 3 due to the poor cohesion. Intertwined between each other, resulting in cross-interference twisted wire X, so that it is not easy to separate the wire
