The plate mounting bracket 302 and the spinneret 304 are provided at equal angles on the outer side of the adjusting circular plate 202. The spinneret holes 305 on the spinneret 304 have different shapes. When it is necessary to spin out a certain shape of fiber, the adjusting circular plate 202 is rotated to the corresponding position of the side groove 204, and the corresponding spinneret 304 is pushed into the installation groove 203. This makes it convenient to select and install the spinneret 304 with the required spinneret hole shape, which is convenient for use.

[0036] The directional positioning component 4 includes a first rod groove 401 formed inside the guide block 307, with both ends of the first rod groove 401 extending to both ends of the guide block 307.

A first electromagnet 410 is fixedly installed on the inner wall of the side cylinder 405 near the fixed plate 1, and the first electromagnet 410 is magnetically connected to the first magnet 409. A socket 412 is installed at the top of the side cylinder 405, and a plug 41 is installed at the top of the pull rod 407. 1. When the connecting plate 404 moves toward the fixed plate 1, the plug 411 can be inserted into the socket 412. After the first electromagnet 410 is energized, it attracts the first magnetic block 409, so that the positioning rod 403 in the receiving groove 301 corresponding to the side groove 204 can be inserted into the first guide groove 205, thereby positioning the direction of the adjusting round plate 202 for easy installation. At the same time, when the positioning rod 403 can move, it drives the plug 411 to be inserted into the socket 412, so that the corresponding plate mounting bracket 302 is engaged with the snap-fit ​​crossbar 503, which facilitates the movement of the required spinneret 304 and improves the installation efficiency.

[0037] The snap-fit ​​mounting assembly 5 includes a top arc plate 501 fixedly mounted on the top of the plate mounting bracket 302. When the plate mounting bracket 302 moves into the side groove 204, the top arc plate 501 and the top ring 208 combine to form a limiting ring. A movable groove 502 is provided in the middle of the top arc plate 501. A snap-fit ​​crossbar 503 is movably mounted inside the movable groove 502. An end block 504 is fixedly mounted on the end of the snap-fit ​​crossbar 503 away from the circular groove 201.

A second electromagnet 511 is fixedly installed on the inner wall of the fixed cylinder 506 away from the locking crossbar 503. The second magnet 510 and the second electromagnet 511 are magnetically connected. When the plug 411 is inserted into the socket 412, the circuit of the corresponding second electromagnet 511 is turned on.

[0038] A spinning assembly includes a porous, irregularly shaped composite fiber spinneret. A discharge pipe 8 is mounted on the top of a fixed plate 1, a feed hopper 6 is mounted on the top of the discharge pipe 8, and an inlet pipe 7 is mounted on the top of the feed hopper 6. A pump body is mounted on the inlet pipe 7. A pipe mounting assembly 9 is installed between the discharge pipe 8 and the fixed plate 1. The pipe mounting assembly 9 includes a mounting bracket 901 mounted at equal angles on the outer wall of the discharge pipe 8. The mounting bracket 901 is located above a receiving groove 301, and a cylinder is fixedly mounted on the mounting bracket 901. 902, the output rod of cylinder 902 is horizontally set, and a connecting sleeve 903 is fixedly installed at the output end of cylinder 902. The connecting sleeve 903 can be engaged with the end block 504. An annular bottom groove 904 is opened at the bottom end of the discharge pipe 8. After the fixing plate 1 and the discharge pipe 8 are installed, the limiting ring can be engaged in the annular bottom groove 904. A hollow groove 905 is opened on one side of the annular bottom groove 904. A first engaging groove 906 is opened on the inner side wall of the annular bottom groove 904 corresponding to the hollow groove 905. Three through slots 907 are provided on the outer side wall of the bottom groove 904, and three second snap-fit ​​slots 908 are provided on the inner side wall of the annular bottom groove 904. The second snap-fit ​​slots 908 correspond one-to-one with the through slots 907. When the limiting ring enters the interior of the annular bottom groove 904, the empty slot 905 corresponds to the top arc plate 501, the through slot 907 corresponds to the positioning slot 209 on the top ring 208, and when the side groove 204 corresponds to one of the plate mounting brackets 302, the corresponding plug 411 is inserted into the socket. In step 412, the second electromagnet 511 is energized, and the locking rod 508 is engaged in the slot 505 on the locking crossbar 503, so that the plate mounting bracket 302 is engaged and fixed with the locking crossbar 503. When the output end of the cylinder 902 retracts, it pulls each locking crossbar 503 toward the discharge pipe 8. On the one hand, it pulls the required spinneret 304 into the mounting slot 203 for easy installation, and on the other hand, it makes the ends of each locking crossbar 503 engage with the discharge pipe 8, improving the stability of the fixation.

[0039] Working principle: During operation, when one type of spinneret 305 needs to be selected for spinnereting, the adjusting disc 202 is rotated so that the side groove 204 on the adjusting disc 202 corresponds to the receiving groove 301 on which the corresponding spinneret 304 is installed. After setting, each first rod groove 401 is energized to generate an attraction force on the first magnetic block 409. At this time, in the receiving groove 301 corresponding to the side groove 204, since the second guide groove 306 corresponds to the first guide groove 205, the connecting plate 404 moves towards the fixed plate 1 under the attraction force, so that the positioning rod 403 moves towards the adjusting disc 202 and enters the first guide groove 205 on both sides of the side groove 204, thereby positioning the adjusting disc 202 for easy installation.

[0040] Install the fixing plate 1 below the discharge pipe 8, so that the top ring 208 is installed inside the annular bottom groove 904 at the bottom of the discharge pipe 8, so that the notch on the top ring 208 corresponds to the empty groove 905, and so that the end block 504 at the end of the snap-fit ​​crossbar 503 is inserted into the connecting sleeve 903 at the output end of the cylinder 902 on the outer wall of the discharge pipe 8.

[0041] When the positioning rod 403 moves toward the adjusting circular plate 202 and enters the first guide groove 205 on both sides of the side groove 204, the corresponding plug 411 is inserted into the socket 412. At this time, the second electromagnet 511 on the corresponding plate mounting bracket 302 is energized and generates a repulsive force on the second magnetic block 510. Under the action of the repulsive force, the locking rod 508 is locked into the locking groove 505 on the locking crossbar 503.

[0042] Activating each cylinder 902 causes the output end of the cylinder 902 to retract, causing each locking crossbar 503 to move towards the discharge pipe 8. The plate mounting bracket 302 used therein engages with the locking crossbar 503, thereby pulling the plate mounting bracket 302 into the side groove 204, allowing the spinneret 304 to enter the mounting groove 203. At this time, the spinneret 304 is located below the discharge pipe 8, and the top arc plate 501 on the plate mounting bracket 302 enters the annular bottom groove 904 from the empty groove 905. The end of the locking crossbar 503 is inserted into the first locking groove 906, while the other locking crossbars 503, since they are not engaged with the plate mounting bracket 302, move towards the fixing plate 1, causing the locking crossbars 503 to be inserted into the through groove 907, the positioning groove 209, and the second locking groove 908, thereby locking and fixing the discharge pipe 8 and the fixing plate 1.

[0043] When in use, the pump body on the feed pipe 7 is turned on, so that the raw material is extruded from the spinneret hole 305 on the spinneret plate 304 through the discharge pipe 8, and then cooled and shaped after extrusion.
