The secondary temperature control wire 249 is located at the bottom of the hollow cavity 24, the cross section of the outer side of the secondary temperature control wire 249 is annular, and the middle of the fixed installation hole 322 is located on the same horizontal plane as the secondary temperature control wire 249, so that the solidified solvent flowing from the secondary leakage through hole 323 and the main outlet hole 343 will pass through the secondary temperature control wire 249 for heat exchange. The bottom end of the delivery connection cylinder 31 adjacent to the spinneret 10 is connected to the output end of the external coagulation solvent delivery device through a pipeline, and the liquid outlet pipe 262 adjacent to the spinneret 10 is connected to the reflux end of the external coagulation solvent delivery device through a pipeline to recycle the coagulation solvent, and the bottom end of another delivery connection cylinder 31 is connected to an external cleaning water pump through a pipeline, and another liquid outlet pipe 262 is connected to an external waste liquid return pool through a pipeline. The liquid outlet pipe 262 is located below the plate heat exchanger 23.

[0042] For example, in one embodiment, before starting to make silk, the external coagulation solvent delivery device will be started, and the coagulation solvent will be diverted through the pipeline, the delivery connection tube 31 and the delivery diversion tube 32, and through the arc diversion plate 354 on the top of the delivery diversion tube 32, so that most of the coagulation solvent will flow out through the multiple main outflow holes 343 to the hollow cavity 24 of the adjacent spinning machine 10, and a small part of the coagulation solvent will flow out through the multiple diversion holes 323 to the hollow cavity 24 of the adjacent spinning machine 10. At the same time, the external cleaning water pump will also be started to put the cleaning pure water into the hollow cavity 24 of the other multiple constant temperature water tanks 21.

[0043] For example, in one embodiment: when starting to make silk, the spinneret 10 dissolves the polymer to form a uniform polymer solution, and transports the polymer solution to the spinneret 12 through the silk outlet elbow 11, and is extruded through the spinneret 12 to form a long and thin liquid stream. The long and thin liquid stream will be in the coagulation solvent in the hollow cavity 24 for a coagulation bath, so that the polymer will be rapidly coagulated to form a fiber 70. Subsequently, the staff will sequentially wind the fiber 70 through two silk outlet wheels 42, multiple spinning wheel groups 45, multiple water tank spinning wheels 47 and two baking wheel groups 52 and wind them on the output end of the wire collecting machine 60. And multiple spinning wheel groups 45 and multiple water tank spinning wheels 47 are alternately arranged, so that the fibers 70 wound through will be cooled and washed by the clean pure water in the multiple hollow cavities 24 away from the spinneret 10, and stabilized and the residual coagulation solvent and impurities will be removed. In addition, when the fibers 70 are wound through the multiple baking spinning wheels 521 alternately arranged, the hot air blower 54 and the multiple heating wires 533 will be started to uniformly heat-set and dry the fibers 70, remove excess water, and obtain the final fiber 70 product and collect it in the wire collecting machine 60.

[0044] At the same time, in the process of forming the fiber 70 by the coagulation bath of the slender liquid flow, the external coagulation solvent delivery device will increase the output power, and the flow-increasing motor 331 of the solvent delivery assembly 30 adjacent to the spinneret 10 will be started, so that the flow-increasing fan blade 332 rotates, and the coagulation solvent liquid flow is accelerated, so that the coagulation solvent liquid flow has an increased impact force on the arc-shaped diverter plate 354 during the upward process of the delivery diverter cylinder 32, so that the diverter guide slide cylinder 352 moves upward along the vertical diverter slot 324, and the diverter spring 351 extends, so that the amount of coagulation solvent liquid flow that can flow out through the main outlet hole 343 and the diversion through hole 323 becomes more, thereby increasing the coagulation solvent liquid in the hollow cavity 24. The flow rate of the flow is increased, and since the thickness of the fixed arc piece 341 gradually decreases from top to bottom, when the diversion guide slide 352 moves upward, the outer ends of the elastic arc-shaped fitting pieces at both ends of the arc-shaped diverter plate 354 will bend downward. In addition, since the top of the outer wall of the elastic arc strip 357 is recessed with a sliding inclined surface 358, when the diversion guide slide 352 moves upward, the elastic arc strip 357 will bend and tilt upward, and then, after the solidified solvent flow impacts upward, most of it will flow out from the multiple main outlet holes 343 under the guidance of the arc-shaped diverter plate 354, the elastic arc-shaped fitting piece and the elastic arc strip 357, and a small part will flow out from the multiple leakage holes 323. A portion of the coagulation solvent flow flowing out of the main outlet hole 343 will impact the arc-shaped drainage surface 241 at one end of the spinneret 10, and will be directed downward to the middle of the hollow cavity 24 under the guidance of the arc-shaped drainage surface 241, the transition arc-shaped surface 243 and the bottom surface of the arc-shaped guide block 242, and at the same time, the impact trigger sliders 222 at both ends of the arc-shaped drainage surface 241 will move toward the outer end along the trigger sliding groove 244, and the arc-shaped abutting sliding surface 252 on the impact trigger slider 222 will slide against the arc-shaped drainage surface 24 1, thereby causing the impact trigger slider 222 to move upward, thereby causing the driven adjustment slider 223 to move upward, thereby pushing the sliding support slide 227 and the linkage trigger slide 226 to move upward, thereby causing the plurality of first linkage shifting posts 254 to move upward, thereby synchronously shifting the linkage guide plate 225 to rotate and move upward, redirecting the reversed solidification solvent flow, so that it flows and exchanges temperature with the fiber 70 in a fixed direction, thereby ensuring stable cooling and solidification of the fiber 70.At the same time, another part of the solidifying solvent flow will impact the arc-shaped guide surface 241 away from one end of the spinneret 10, and will also impact the outer end of the plate-shaped heat exchanger 23 under the guidance of the arc-shaped guide surface 241, the transition arc-shaped surface 243 and the arc-shaped guide block 242, and make the two impact trigger sliders 222 on the arc-shaped guide surface 241 move toward the outer end along the two trigger sliding grooves 244 respectively, thereby making the two heat exchange trigger slide columns 255 and the heat exchange temperature uniformity slide bar 228 move upward, so that the second linkage shift column 256 moves upward with it, so that the plate-shaped heat exchanger 23 rotates, increasing the impact area, so that the solidifying solvent flow after the flow temperature exchange of the fiber 70 will impact the inner end of the plate-shaped heat exchanger 23, thereby quickly performing heat exchange and ensuring the uniformity of the temperature of the hollow cavity 24.

[0045] For example, in one embodiment: when the solvent delivery assembly 30 away from the multiple constant temperature water tanks 21 on the spinneret 10 needs to cool and wash the fiber 70, the constant temperature cooling element 22 therein will also perform actions similar to those in the above embodiment to cool and wash the fiber 70 at a uniform temperature.
