[0002] Chemical fibers are made from natural or synthetic polymers, through a series of processes including spinning solution preparation, spinning, and post-processing.

The pulling of the handle 303 drives the sleeve block 301 to slide on the limit rod 304 through the card column 302. When the sleeve block 301 moves to the appropriate position, the card plate 310 is then rotated, and the card plate 310 is rotated to make the card column 302 stuck in the corresponding card slot 311, thereby facilitating the limiting of the position of the sleeve block 301.

When the sleeve 301 moves to the appropriate position, the clamping plate 310 is rotated again, and the clamping column 302 is clamped in the corresponding clamping slot 311 by the rotation of the clamping plate 310, thereby facilitating the position of the sleeve 301.

[0038] When the reaction box 1 needs to be shaken as a whole, the driving motor 418 is operated to rotate the transmission rod 416, and the rotation of the transmission rod 416 drives the cam 415 to rotate. The pulley 414 is fitted to the edge of the cam 415 by the elastic force of the second spring 412, and the rotation of the cam 415 causes the slide 407 to move. The movement of the slide 407 drives the slide rod 401 to move through the sleeve 405 on the docking plate 406, and the slide rod 401 will slide inside the slide groove 404 to increase the stability of the movement of the slide rod 401. The movement of the slide rod 401 pushes the support plate 2 on the first pin 201 through the support plate 4 to shake up and down quickly, so that the inside of the reaction box 1 is more evenly mixed and reacted.
