The disk rotator 22 is a prior art.

[0040] Specifically, in order to prevent the separation of plastic fiber spinning from being time-consuming and laborious due to excessive winding, and also to be able to wind more plastic fiber spinning evenly after adjusting the winding position of the collection enclosure 32, the lifting member 33 includes a lifting rod 331, a guide sleeve 332 and a lifting driver 333, the lifting rod 331 is fixedly connected to the collection bottom plate 31, the guide sleeve 332 is fixedly connected to the frame 1, the lifting rod 331 is slidably connected to the guide sleeve 332 in the vertical direction, and the lifting driver 333 drives the lifting rod 331 to slide on the guide sleeve 332. The lifting driver 333 is a prior art.

[0041] As can be known from the above, the spinning solution is transported into the solution tank 211. The spinning disk 21 is driven to rotate by the disk rotator 22. After the spinning disk 21 rotates, by using the centrifugal force, the spinning solution in the solution tank 211 is thrown out along the spinning slot 212 under the rotating force of high-speed rotation, and is quickly cooled through high-speed movement. The formed plastic fiber spinning is collected by the collection enclosure 32. The operation is simple, large-scale production of plastic fiber spinning can be achieved, and the lifting rod 331 can be moved up and down in the guide sleeve 332 by the lifting driver 333, so as to adjust the height of the collection enclosure 32, thereby adjusting the winding position of the collection enclosure 32, so as to avoid the plastic fiber spinning only winding part of the position of the collection enclosure 32, in case that when separating the plastic fiber spinning, it is time-consuming and laborious due to excessive winding. At the same time, after adjusting the winding position of the collection enclosure 32, more plastic fiber spinning can be evenly wound.

[0042] In this embodiment, the collection enclosure 32 includes twelve collection vertical plates 321. The twelve collection vertical plates 321 are movably connected to the collection bottom plate 31 and form an annular structure at intervals along the circumferential direction. The distance between the collection vertical plate 321 and the spinning disk 21 can be adjusted and set through the adjusting part 34. Thus, through the circumferential annular interval arrangement of the twelve collection vertical plates 321, large-scale production of plastic fiber spinning can be realized, and more plastic fiber spinning can be collected each time.

[0043] Specifically, the adjusting part 34 includes a slider 341, a chute 342 and a driving cylinder 344. The slider 341 is fixedly connected to the collection vertical plate 321. The chute 342 is arranged on the collection bottom plate 31 along the radial direction. The slider 341 is slidably arranged in the chute 342. The driving cylinder 344 is installed on the collection bottom plate 31 and is used to drive the slider 341 to move. Thus, the radial movement of the collection vertical plate 321 on the collection bottom plate 31 can be realized, the reliability of the position adjustment of the collection vertical plate 321 is improved, and at the same time, the electric control adjustment operation is convenient. The driving cylinder 344 is a prior art.

[0044] Specifically, the spinning slot 212 is gradually inclined upward from inside to outside along the radial direction. Thus, through the arrangement that the spinning slot 212 is gradually inclined upward from inside to outside along the radial direction, it plays a guiding role before the formation of the plastic fiber spinning, helps the plastic fiber spinning to be accurately collected by the collection vertical plate 321 when it is formed, thereby avoiding excessive loss of the plastic fiber spinning, and at the same time increasing the spinning distance after centrifugal throwing.

[0045] Specifically, three annular protrusions 2111 are provided in the solution tank 211. The three annular protrusions 2111 are arranged radially, and the heights of the three annular protrusions 2111 decrease one by one from the inside to the outside. Through the arrangement of the three annular protrusions 2111 with the heights decreasing one by one from the inside to the outside, when the device is static, the spinning solution in the solution tank 211 will not flow into the center of the wire outlet plate 21, reducing the loss of the spinning solution.

[0046] Specifically, each annular protrusion 2111 is gradually inclined upward from the inside to the outside in the radial direction. Thus, through the arrangement of each annular protrusion 2111 being gradually inclined upward from the inside to the outside in the radial direction, it is convenient for the spinning solution to be smoothly introduced into the wire outlet groove 212.

[0047] Continuing in this embodiment, the inclination angle of the annular protrusion 2111 is 20 degrees.

[0048] Continuing in this embodiment, the inclination angle of the wire outlet groove 212 is 10 degrees.

[0049] Embodiment 2

[0050] As Figures 6 to 9 shown, the difference between this embodiment and Embodiment 1 is that the adjusting part 34 includes a slider 341, a chute 342, and a fastening component 343. The slider 341 is fixedly connected to the collecting vertical plate 321. The chute 342 extends radially on the collecting bottom plate 31. The slider 341 is slidably arranged in the chute 342. The fastening component 343 is used to lock and fix the slider 341 in the chute 342. Thus, through the adjustable setting of the distance between the collecting vertical plate 321 and the wire outlet plate 21, by disassembling the fastening component 343 to adjust the fixed position of the slider 341 in the chute 342, the length of the plastic fiber spinning can be regulated as needed. Specifically, a long strip through hole 3421 is provided in the chute 342. The long strip through hole 3421 extends radially. The fastening component 343 includes a bolt 3431 and a nut 3432. A through hole 3411 is provided on the slider 341. The head of the bolt 3431 abuts against the collecting bottom plate 31. The rod body of the bolt 3431 sequentially passes through the long strip through hole 3421 and the through hole 3411 and then is screwed with the nut 3432. Thus, through the bolt 3431 and the nut 3432, the slider 341 is fixedly connected through the long strip through hole 3421. On the one hand, it is convenient for fastening and disassembling, and on the other hand, the collecting vertical plate 321 is fixed more firmly.
