  • a moving bracket guiding portion 21 is respectively arranged on both sides of the moving bracket 2, and the spinning assembly 1 can ascend and descend along the moving bracket guiding portion 21; a plurality of limiting holes can be arranged on the moving bracket guiding portion 21 at intervals, for example, a stopper pin 22 and other limiting member is inserted into the limiting hole at a corresponding height to limit the lifting direction of the spinning assembly.
  • the rotary movement control portion includes a second lifting driving mechanism 42, a second slide rail 33 and a rotation driving mechanism 6, and the second slide rail 33 is arranged along the short axis direction of the spinneret portion 14.
  • the spinneret portion 14 When the spinning assembly 1 is in a normal spinning working state, the spinneret portion 14 is arranged at the top of the spinning box and communicates with a spinning shaft 5, and the spinneret portion 14 is downward, as shown in Fig. 4a . When the spinneret portion 14 needs to be replaced, the spinning production is interrupted.
  • the second lifting driving mechanism 42 drives the spinning assembly 1 to ascend to a position along the vertical direction, as shown in Fig. 4b , and the stop pin 22 is inserted into the limiting hole formed in the corresponding height of the moving bracket guiding portion 21 to limit the spinning assembly 1 as shown in Fig. 4c .
  • a driving force (the driving force can be manually applied, for example, thrust; or can be applied by an external power mechanism and the like) of translating along the short axis direction of the spinneret portion is applied to the entirety of the moving bracket 2 and the spinning assembly 1, so that the entirety of the moving bracket 2 and the spinning assembly 1 translates along the second slide rail 31 until the spinning assembly 1 staggers to the spinning shaft, as shown in Fig. 4d to Fig. 4e .
  • the rotation driving mechanism 6, such as a manual turbine vortex reducer, outputs the power to the rotating shaft 16, so that the entirety of the spinning assembly rotates on the moving bracket 2, after rotating to a certain angle, the orientation of the spinneret portion of the spinning assembly is an orientation facilitating the maintenance as shown in Fig. 4f to Fig. 4g , for example, the spinneret portion of the spinning assembly is obliquely upward relative to the horizontal direction after positive rotation for certain degrees, for example, the spinneret portion of the spinning assembly is upward after positive rotation for 180 degrees. Therefore, the spinneret portion 14 can be disassembled, and another spinneret portion 14 is replaced.
  • the rotation driving mechanism 6 outputs the power to the rotating shaft 16, so that the entirety of the spinning assembly reversely rotates on the moving bracket 2, the orientation of the spinneret portion of the spinning assembly rotating to a certain angle is an orientation facilitating the spinning toward the spinning shaft 5, for example, the spinneret portion of the spinning assembly is turned over to be downward after reverse rotation for certain angles, for example, the spinneret portion of the spinning assembly is turned over to be downward after reverse rotation for 180 degrees.
  • a driving force of translating along the short axis direction of the spinneret portion is applied to the entirety of the moving bracket 2 and the spinning assembly 1, so that the entirety of the moving bracket 2 and the spinning assembly 1 translates onto the a position where the spinning assembly 1 is aligned to the spinning shaft up and down.
  • the stop pin 22 inserted into the limiting hole of the moving bracket guiding portion 21 is taken out, the second lifting driving mechanism 42 drives the entirety of the moving bracket 2 and the spinning assembly 1 to descend along the vertical direction until the spinneret portion 14 is connected with the spinning shaft 5.
  • the replacement maintenance of the spinneret portion 14 is accomplished, the spinning production of the elastic fibers can be recovered, and cleaning, assembly replacement and other subsequent offline maintenance can be performed on the disassembled spinneret portion 14 subsequently. Therefore, in the solution, the spinneret portion and the temperature control portion only need to be separated and disassembled instead of disassembling the entirety of the spinning assembly, thereby reducing the range of assemblies requiring cleaning, replacement and other maintenance and reducing the workload of cleaning, replacement and other maintenance. In addition, the online maintenance time is short, the influence on spinning production is little, and the production efficiency is improved.
