A regenerated polyester fiber spinning device

Abstract

The invention relates to the technical field of spinning equipment and specifically relates to a regenerated polyester fiber spinning device which comprises an upper box body, a lower box body, a discharging mechanism, an extruding mechanism, a switching mechanism, a driving mechanism, a distribution plate, a spinneret mechanism, a supporting mechanism, a second filtering plate and a discharging box. According to the regenerated polyester fiber spinning device disclosed by the invention, when material is completely extruded by a pressing plate to rise, a first filtering plate can be switched to be arranged at the top of a discharging opening, and the material can be discharged in a process that the pressing plate upwards returns; when the press plate moves to the top end, an area between the pressing plate and the second filtering plate can be filled with raw material, the pressing plate is driven again to move downwards, next processing is performed, circulation is performed in the way, and the material can be fed without waiting for the press plate to rise to the initial position; a third rotating motor and a fourth rotating motor can drive the spinneret plate to move; furthermore, two spinneret hole areas with different net hole diameters are formed on the surface of the spinneret plate, and a coincidence proportion among the first spinneret hole area, the second spinneret hole area and a distribution hole can be adjusted to adjust production of filaments with different diameters.

Description

technical field [0001] The invention relates to the technical field of spinning equipment, in particular to a regenerated polyester fiber spinning device. Background technique [0002] The raw materials of regenerated polyester fiber are waste polyester bottle flakes and waste polyester textile scraps. The current regenerated polyester fiber spinning device is mainly composed of component headgear, pressure plate, distribution plate and spinneret. Extrusion can realize spinning production. [0003] Most of the current spinning devices adopt the structure of side feeding and top surface pressing. When the pressing plate completely extrudes the molten amount and moves to the bottom, it needs to rise to the top of the feeding port again before the next feeding can be carried out, so that the processing process In the process, there will be a waiting time for the pressing plate to reset, which makes the whole spinning process longer and less efficient; during processing, only s...

[0003] Most of the current spinning devices adopt the structure of side feeding and top surface pressing. When the pressing plate completely extrudes the molten amount and moves to the bottom, it needs to rise to the top of the feeding port again before the next feeding can be carried out, so that the processing process In the process, there will be a waiting time for the pressure plate to reset, which makes the whole spinning process longer and less efficient; during processing, only spinning with a fixed diameter can be processed, and the spinneret cannot be quickly switched
