Exchangeable Spin Beam {EXCHANGABLE SPIN BEAM}

The present invention relates to an interchangeable spin beam, and more particularly, by configuring two types of spinning means for spinning by receiving a melt from the spin beam of a melt spinning device used for melt spinning of synthetic fibers to be exchangeable and a spin beam for improving process efficiency.

In general, fiber spinning, which is a process for manufacturing fibers, is a process of manufacturing yarn by spinning through a hole provided in a nozzle or a spin pack using a natural or synthetic polymer.

Melt spinning, which is a typical fiber spinning method used in the production of synthetic fibers such as polyamide, polyester, and polyurethane, is made by a melt spinning device.

As an example of a known technique, Korean Patent Registration No. 10-0074287 discloses a heater box having a cylindrical inner jacket, a block means having a plurality of melt pump pipes, and a plurality of blocks fixed to the bottom of the block means and positioned in a circular arrangement A nozzle assembly each comprising a nozzle head having a vertical hole of A melt spinning apparatus comprising an independently driven melt extruding means for discharging into the assembly and a rotating means around which the melt extruding means is circularly arranged is constituted.

On the other hand, schematically describing the operation process of a conventional melt spinning device, a polymer material is put into the supply unit, heated and melted, and then supplied by a spin beam, and the gear pump of the spin beam is a polymer melt at high temperature and high pressure. The molten solution is supplied to each spinning means through a distribution pipe inside the heat block. The molten solution is discharged at high pressure into the air through the pores formed in the spinning means, cooled and solidified by the airflow, and is made into filaments or staples through post-processing.

The spin beam of the melt spinning apparatus as described above is provided with a spinning means of a nozzle type or a spinning pack type.

The spinning pack-type spinning means includes, for example, a pack cover and a pack case, as known in Korean Patent Registration No. 10-1829268, and a rotating means for rotating the pack case inside, coupled between the pack cover and the spinneret, It consists of a pressure plate having a wire mesh filter, and a spinneret coupled to the lower part of the pack case and extruding the molten solution passing through the pressure plate.

The nozzle type excludes the pack case structure as described above and is configured to mount a nozzle that extrudes and spins the melt.

The present invention provides a spin beam configured so that the spin beam of the melt spinning apparatus used for manufacturing synthetic fibers is interchangeable with a spinning pack-type spinning means or a nozzle-type spinning means.

Therefore, in the present invention, the melt spinning apparatus of the prior art is configured to mount different separate spin beams having a spinning pack-type spinning means or a nozzle-type spinning means. Since it can be replaced and installed, there is an advantage in that the process loss can be significantly reduced and the operation rate of the line can be improved.

In addition, the present invention has the effect of remarkably increasing efficiency and productivity because the spinning means can be exchanged from the spin beam as needed, so that the system can be operated throughout the production of low-quality products and high-quality products.
