[0042] The shunt guiding element 35 includes a shunt spring 351 and a shunt guiding sliding cylinder 352. The bottom end of the shunt spring 351 is installed at the top of the spring mounting ring 325. On both sides of the shunt guiding sliding cylinder 352, shunt mounting blocks 353 respectively protrude. The two shunt mounting blocks 353 are respectively slidably installed in the two vertical shunt chutes 324, and the bottom end of the shunt guiding sliding cylinder 352 is connected to the top end of the shunt spring 351. An arc-shaped shunt plate 354 is arranged at the top of the shunt guiding sliding cylinder 352. Elastic arc-shaped fitting pieces respectively protrude at both ends of the arc-shaped shunt plate 354, and the outer wall of the elastic arc-shaped fitting piece is slidably attached to the inner wall of the fixed arc-shaped piece 341. At both ends of the inner wall of the shunt guiding sliding cylinder 352, shunt discharge holes 356 are respectively recessed. At the bottom of each shunt discharge hole 356, an elastic arc-shaped strip 357 protrudes. A sliding inclined surface 358 is recessed at the top of the outer wall of the elastic arc-shaped strip 357. An elastic triangular strip 359 protrudes from the inner wall of the elastic arc-shaped strip 357.

[0043] For example, in one embodiment: The sliding inclined surface 358 is slidably fitted to the inner wall of the fixed arc-shaped piece 341, and the inclination of the sliding inclined surface 358 is less than the inclination of the inner wall of the fixed arc-shaped piece 341. The secondary temperature control wire 249 is located at the bottom of the hollow cavity 24. The cross-section outside the secondary temperature control wire 249 is annular, and the middle part of the fixed mounting hole 322 is on the same horizontal plane as the secondary temperature control wire 249, so that the solidified solvent flowing out from the diversion through holes 323 and the main outflow holes 343 will pass through the secondary temperature control wire 249 for heat exchange. The bottom end of the conveying connection cylinder 31 adjacent to the spinneret 10 is connected to the output end of the external conveying device of the solidified solvent through a pipeline, and the liquid outlet pipe 262 adjacent to the spinneret 10 is connected to the reflux end of the external conveying device of the solidified solvent through a pipeline to recycle the solidified solvent. The bottom end of the other conveying connection cylinder 31 is connected to the external cleaning water pump through a pipeline, and the other liquid outlet pipe 262 is connected to the external waste liquid return pool through a pipeline. The liquid outlet pipe 262 is located below the plate heat exchanger 23.

[0044] For example, in one embodiment: Before starting to make filaments, the external conveying device of the solidified solvent will be started, and the solidified solvent will pass through the pipeline, the conveying connection cylinder 31 and the conveying diversion cylinder 32, and be diverted by the arc-shaped diversion plate 354 at the top of the conveying diversion cylinder 32, so that most of the solidified solvent flows out through the multiple main outflow holes 343 into the hollow cavity 24 adjacent to the spinneret 10, and a small part of the solidified solvent will flow out through the multiple diversion through holes 323 into the hollow cavity 24 adjacent to the spinneret 10. At the same time, the external cleaning water pump will also be started to inject the cleaning pure water into the hollow cavity 24 of the other multiple constant temperature water tanks 21.

[0045] For example, in one embodiment: When starting to make filaments, the spinneret 10 dissolves the polymer to form a uniform polymer solution, and transports the polymer solution to the spinneret head 12 through the wire outlet elbow 11, and extrudes it through the spinneret head 12 to form a slender liquid stream. The slender liquid stream will be in the solidified solvent in the hollow cavity 24 for a coagulation bath, so that the polymer quickly solidifies to form the fiber 70. Subsequently, the staff will wind the fiber 70 around the output end of the winding machine 60 through two wire outlet wheels 42, multiple spinning wheel groups 45, multiple water tank spinning wheels 47 and two baking wheel groups 52 in sequence. The multiple spinning wheel groups 45 and the multiple water tank spinning wheels 47 are arranged alternately, so that the wound fiber 70 will be cooled and washed by the cleaning pure water in the multiple hollow cavities 24 far from the spinneret 10 to be stabilized and remove the residual solidified solvent and impurities. In addition, when the fiber 70 is wound through the multiple alternately arranged baking spinning wheels 521, the hot air blower 54 and the multiple heating wires 533 will be started to uniformly heat-set and dry the fiber 70 to remove the excess moisture, and obtain the final fiber 70 product and collect it in the winding machine 60.

[0046] Meanwhile, during the process of forming the fiber 70 by subjecting the slender liquid flow to a coagulation bath, the delivery device of the external coagulation solvent 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, causing the flow-increasing fan blade 332 to rotate, accelerating the coagulation solvent liquid flow, so that the impact force of the coagulation solvent liquid flow on the arc-shaped flow dividing plate 354 increases during the upward movement in the delivery and diversion cylinder 32, causing the diversion guide sliding cylinder 352 to move upward along the vertical diversion chute 324, and the diversion spring 351 to extend, so that the quantity of the coagulation solvent liquid flow flowing out through the main outflow holes 343 and the diversion through holes 323 increases, thereby increasing the flow rate of the coagulation solvent liquid flow in the hollow cavity 24. Moreover, since the thickness of the fixed arc-shaped piece 341 gradually decreases from top to bottom, when the diversion guide sliding cylinder 352 moves upward, the outer ends of the elastic arc-shaped fitting pieces at both ends of the arc-shaped flow dividing plate 354 will bend downward. Additionally, since the top of the outer wall of the elastic arc-shaped strip 357 is recessed with a sliding inclined surface 358, when the diversion guide sliding cylinder 352 moves upward, the elastic arc-shaped strip 357 will bend upward and tilt. Thus, after the coagulation solvent liquid flow impacts upward, under the guidance of the arc-shaped flow dividing plate 354, the elastic arc-shaped fitting pieces and the elastic arc-shaped strip 357, most of it will flow out from the multiple main outflow holes 343, and a small part will flow out from the multiple diversion through holes 323. A part of the coagulation solvent liquid flow flowing out from the main outflow holes 343 will impact the arc-shaped diversion surface 241 at one end adjacent to the spinneret 10, and under the guidance of the arc-shaped diversion surface 241, the transition arc-shaped surface 243 and the bottom surface of the arc-shaped diversion block 242, it will change direction towards the middle of the hollow cavity 24. At the same time, the impact trigger sliders 222 at both ends of the arc-shaped diversion surface 241 will move outward along the trigger sliding groove 244. Also, since the arc-shaped abutting sliding surface 252 on the impact trigger slider 222 slides and abuts against the arc-shaped diversion surface 241, the impact trigger slider 222 will move upward, causing the driven adjustment sliding plate 223 to move upward accordingly, and then pushing the sliding abutting sliding column 227 and the linkage trigger slide bar 226 to move upward, causing the multiple first linkage dialing columns 254 to move upward, and then synchronously dialing the linkage diversion plate 225 to rotate and move upward, redirecting the coagulation solvent liquid flow after the direction change, so that it flows and exchanges temperature with the fiber 70 in a fixed direction, ensuring stable cooling, temperature reduction and solidification of the fiber 70.Meanwhile, the coagulation solvent liquid flow of another part will impact the arc-shaped drainage surface 241 far away from one end of the spinneret 10, and it will also impact the outer end of the plate heat exchanger 23 under the guidance of the arc-shaped drainage surface 241, the transition arc surface 243 and the arc-shaped diversion block 242, and cause the two impact trigger sliders 222 on the arc-shaped drainage surface 241 to move outward along the two trigger sliding grooves 244 respectively, thereby causing the two heat exchange trigger sliding columns 255 and the heat exchange temperature equalizing strip 228 to move upward, causing the second linkage dial post 256 to move upward accordingly, causing the plate heat exchanger 23 to rotate, increasing the impact area, so that the coagulation solvent liquid flow after flowing and temperature exchanging the fiber 70 will impact the inner end of the plate heat exchanger 23, and then quickly conduct heat exchange and the uniformity of the temperature of the hollow cavity 24.

[0047] For example, in one embodiment: when the solvent delivery assembly 30 far away from the plurality of 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 evenly cool and wash the fiber 70.
