Description

Technical Field

[0001] The utility model belongs to the technical field of spinnerets, in particular to a spinneret for producing regenerated polyester filaments. Background Art

[0002] Polyester filament is a filament made of polyester, which is an important variety of synthetic fibers. Polyester is a fiber-forming polymer made from purified terephthalic acid or dimethyl terephthalate and ethylene glycol through esterification or transesterification and polycondensation, and then made into fibers through spinning and post-processing.

[0003] The utility model with announcement number CN220057127U discloses a spinneret for producing high-elastic recycled polyester filament, including a shell, a motor on the top of the shell, a rotating shaft fixedly connected to the output end of the motor, the rotating shaft extends to the interior of the shell, a turntable fixedly connected to the bottom of the rotating shaft, a spinneret is arranged inside the shell, a first spinneret assembly is arranged inside the turntable, a second spinneret assembly is arranged inside the turntable, a third spinneret assembly is arranged inside the turntable, a fourth spinneret assembly is arranged inside the turntable, and an isolation frame is arranged inside the turntable.

[0004] In the process of implementing this application, it was found that the technology has the following problems: in the above patent documents, the turntable is mainly driven by a motor and a shaft to rotate, so that polyester filaments of different shapes can be produced; in the long-term production process, both sides of the spinneret may be contaminated, one side is the surface where the spinneret hole is located, this side will directly contact the spinning solution, the spinneret hole may be blocked by mechanical impurities, carbon fiber, gel, etc., resulting in uneven spinning and affecting the quality of the filaments; the other side is the external surface that is not in direct contact with the spinning solution, this side may be contaminated by dust, oil and other pollution in the environment, affecting the heat dissipation and overall performance of the spinneret. When the spinneret hole is partially blocked, it may cause uneven fineness of the raw silk and produce problems such as thin and hairy silk, so the spinneret needs to be cleaned; in the above patent document, if you want to clean the spinneret in the document, you need to disassemble the different spinnerets in the shell, and the spinneret in the above document is installed on a turntable, and the turntable is fixedly connected to the rotating shaft. The length of the rotating shaft is less than the height of the cylindrical shell. It is difficult to use tools to clean both sides of the spinneret, and it is also inconvenient to disassemble and clean the spinneret.

[0005] For this reason, a spinneret for producing regenerated polyester filaments is proposed. Utility Model Content
