  • the limit pin 22 inserted in the limiting hole of the moving bracket guiding portion 21 is taken out, and the second The lifting drive mechanism 42 drives the moving bracket 2 and the spinning member 1 as a whole to be lowered in the vertical direction until the spinning section 14 is connected to the spinning tunnel 5.
  • the replacement and maintenance of the spinning section 14 is completed, and the spinning production of the elastic fiber can be resumed, and the detached spinning section 14 can be subsequently subjected to subsequent offline maintenance such as cleaning and replacement of components.
  • subsequent offline maintenance such as cleaning and replacement of components.
  • the solution only needs to separate and disassemble the spinning part from the temperature control part without removing the spinning part as a whole, thereby reducing the range of parts required for maintenance such as cleaning and replacement, and reducing maintenance work such as cleaning and replacement.
  • the short online maintenance time has less impact on spinning production and improves production efficiency.
