[0002] Spinning is the process of forming chemical fibers by extruding a colloid solution or melt of certain high molecular compounds from the spinneret hole. After the polymer melt is extruded from the spinneret plate as a nascent fiber, it first needs to pass through the slow cooling wind-protected zone, which is beneficial to maintaining the shape of the fiber during the cooling process and preventing deformation caused by rapid cooling. That is, by controlling the cooling rate of the nascent fiber, the surface quality of the fiber is ensured to improve the microstructure of the fiber and enhance the dimensional stability of the fiber. However, the current wind-protected zone is composed of a wind-protected channel installed in the shell below the spinneret plate. However, in actual production, the applicant found that the process control of the slow cooling wind-protected zone needs to be optimized according to different fiber specifications and production processes, so different spinning products require different lengths of the wind-protected channel. Currently, the length of the wind-protected channel is mainly adjusted by replacing the shell, which is inconvenient to operate, inefficient, and affects production. SUMMARY
