The embodiment of the present invention provides an elastic fiber dry spinning mechanism, comprising: a spinning component and a rotation movement control part; the spinning component comprises a temperature control part and a spinning part which are detachably stacked; A movement control portion is used to rotate the spinning member in a lift, a translation, and a translational direction to change the orientation of the spinning member to facilitate maintenance of the orientation of the spin section.

The lifting includes an upward or downward movement of a raised or lowered position relative to a reference position of the spinning member, such as a vertical axis of the spinning member, the lifting being opposite to the vertical surface A reference position of the spinning component moves up and down. The translation includes a parallel movement about a certain reference position of the spinning member, such as a vertical axis of the spinning member, the translation being a certain horizontal plane relative to the spinning portion The reference position is moved, and can be moved left and right along the long axis direction of the spinning section, or can be moved back and forth along the short axis direction of the spinning section, and the like. The orientation of the spinneret for facilitating maintenance may include, but is not limited to, an upward orientation of the spinneret, and the maintenance may include, but is not limited to, Wash and / or replace.

In the dry spinning production process of elastic fibers such as spandex, the spinning member is usually disposed above the spinning box and the spinning portion is adjacent to the spinning box, and the spinning box may include, but is not limited to, a spinning tunnel, a spinning portion The spinneret is oriented in the spinning tunnel, and the polymer solution of the elastic fiber is sprayed into the spinning tunnel through the respective spinnerets of the spinning section to perform the subsequent processing of the elastic fiber such as solvent evaporation.

Therefore, the spinning section usually requires regular maintenance intervals with a certain maintenance period.

For example, in the case where the spinning box is located below the spinning part, the spinning section is facing downward in the normal spinning operation state (ie, the spinning heads of the spinning section are directed toward the spinning tunnel below the spinning section). It is not convenient to maintain such as cleaning, replacement, etc. when the spinning section is facing downward. Rotating the movement control portion to raise the spinning member to separate the spinning member from a spinning box located below the spinning member, to translate the spinning member to rotate the spinning member Dissolving the spinning box, and rotating the spinning member about the translational direction to change the orientation of the spinning member to facilitate maintaining the orientation of the spinning portion, such as rotating the spinning member about the translational direction to The spinneret is facing upward. Thus, the spinning portion can be separated from the temperature control portion, and the other spinning portion (such as the spare cleaning spinning portion) can be detachably stacked with the temperature control portion. After the replacement is completed, the rotational movement control portion may be reversely moved or rotated according to the original movement trajectory, such as rotating the spinning member about the translational direction to change the orientation of the spinning member to another of the spinning portions to facilitate Orienting the spinneret of the spin box (as the spinneret of the spin section faces downward); translating the spinning member to align the spinner member with the spin box up and down; The spinning member is lowered to connect the spinning member to the spinning box, so that the spinning member can be restored to the original working state.

Therefore, the online maintenance time is short and the impact on spinning production is small.

(1) The following may further illustrate an optional technology of the embodiment of the present invention by taking the spinning component including the metering driving device, the metering device, the interface conversion portion, the temperature control portion and the spinning portion as an example in conjunction with FIG. 1 to FIG. 2g. The implementation is similar for the spinning components having other structures, and will not be described in detail in the embodiments of the present invention.

As shown in FIG. 1, an elastic fiber dry spinning mechanism according to an embodiment of the present invention includes a spinning member 1, a moving bracket 2, and a rotational movement control portion. The spinning component 1 comprises at least one metering device 11, an interface converting portion 12, a temperature controlling portion 13, a spinning portion 14, and at least one metering driving device 15, a metering device 11, an interface converting portion 12, and a temperature controlling portion 13. The spinning portion 14 and the metering driving device 15 are stacked one on top of the other in a relatively fixed position, and at least the temperature control portion 13 and the spinning portion 14 are detachable. Both ends of the spinning member 1 are provided with a rotating shaft 16 which is coupled to the moving bracket 2 via the rotating shaft 16, so that the spinning member 1 as a whole can be rotated on the moving bracket 2. The rotary movement control unit includes a first elevation drive mechanism 41, a first slide rail 31, a moving slide rail 32, and a rotary drive mechanism 6. The first slide rail 31 and the moving slide rail 32 are connected to each other at the spinning section. The long axis direction of 14 and the moving rail 32 can be raised and lowered with the spinning member 1 and the moving bracket 2.

When the spinning member 1 is in the normal spinning operation state, the spinning section 14 is provided at the top of the spinning box and communicates with the spinning tunnel 5, and the spinning section 14 faces downward as shown in Fig. 2a. When the spinning section 14 needs to be replaced, the spinning production is interrupted.

The first lifting drive mechanism 41 drives the moving rail 32, the moving bracket 2, and the spinning member 1 as a whole to rise in the vertical direction to a position equal to the first rail 31, as shown in Fig. 2b. Applying a driving force to the moving bracket 2 and the spinning member 1 as a whole in the direction of the longitudinal axis of the spinning thread (the driving force can be manually applied, such as a thrust; or, can be applied by means of an external power mechanism, etc.), so that the moving bracket 2 is moved The spinning member 1 is integrally translated along the moving rail 32 onto the first rail 31 as shown in Fig. 2c. After the spinning member 1 is completely moved to the first rail 31, it is completely misaligned with the spinning tunnel, as shown in Fig. 2d. The rotary drive mechanism 6 may include, but is not limited to, a manual turbine worm reducer, and the rotary drive mechanism 6 outputs power to the rotary shaft 16 such that the spinning member as a whole rotates on the moving bracket 2 as shown in Figs. 2e and 2f. The orientation of the spin section rotated to a certain angle of the spinning member is in a maintenance-friendly orientation, such as the spin section of the spinning member being turned upwards after being rotated 180 degrees in the forward direction, as shown in Fig. 2g. Thus, the spinning portion 14 can be detached and the other spinning portion 14 can be replaced.

After the replacement of the spinning section 14 is completed, the rotary drive mechanism 6 outputs the power to the rotating shaft 16, so that the spinning member as a whole rotates in the opposite direction on the moving bracket 2, and the direction of the spinning portion of the spinning member rotated to a certain angle is facilitated to the spinning. The direction of the spinneret 5 is reversed, and if the reverse rotation is 180 degrees, the spinning portion of the spinning member is turned downward. Next, a driving force that translates in the direction of the longitudinal axis of the spinning wire is applied to the moving bracket 2 and the spinning member 1 as a whole, so that the moving bracket 2 and the spinning member 1 are integrally translated along the first rail 31 onto the moving rail 32, The spinning member 1 is completely moved to the upper and lower sides of the spinning tunnel after moving the slide rail 32. Thereafter, the first lift drive mechanism 41 drives the moving slide rail 32, 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.

Thus, 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. It can be seen that 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. In addition, the short online maintenance time has less impact on spinning production and improves production efficiency.

(2) Next, it is possible to further illustrate another embodiment of the present invention by taking the spinning member including the metering driving device, the metering device, the interface conversion portion, the temperature control portion, and the spinning portion as an example in conjunction with FIG. 3 to FIG. 4g.
