[0026] An embodiment of the present utility model discloses a high-strength fiber spinning device.

[0027] Embodiment 1

[0028] The present utility model provides a high-strength fiber spinning device as shown in Figures 1-3 which includes a spinneret plate 1 and a plurality of spinneret holes 2 opened inside the spinneret plate 1. An inner-threaded installation pipe 3 is fixedly penetrated through the center inside the spinneret plate 1. A plurality of sealing plates 4 arranged symmetrically in a surrounding manner are slidably sleeved outside the spinneret plate 1. The sealing plate 4 is a U-shaped sealing plate. The inner wall of the sealing plate 4 is arranged in cooperation with the spinneret holes 2. A moving guiding mechanism is provided between the sealing plate 4 and the spinneret plate 1;

[0029] A fixed rod 5 is fixedly provided on the outer wall of the sealing plate 4. A swivel ring 6 is rotatably sleeved on the outer wall of the inner-threaded installation pipe 3. A plurality of push rods 7 arranged symmetrically in a surrounding manner are fixedly provided on the outer wall of the swivel ring 6. The push rods 7 are in contact and cooperation with the fixed rod 5.

[0030] Before high-strength fiber spinning, determine the number of fibers required inside the fiber bundle. Subsequently, rotate the swivel ring 6 under the support of the inner-threaded installation pipe 3, so that the swivel ring 6 drives a plurality of push rods 7 to rotate. Since the push rods 7 are in contact with the fixed rod 5, the fixed rod 5 can be pushed to drive the sealing plate 4 to slide under the support of the moving guiding mechanism. At this time, a plurality of sealing plates 4 can shield a plurality of spinneret holes 2 on the same straight line, so that the number of spinneret holes 2 can meet the spinning requirements.

[0031] Embodiment 2

[0032] Based on Embodiment 1, in order to stably support the movement of the sealing plate 4 when the sealing plate 4 is pushed, as shown in Figures 1-2As shown, the moving guiding mechanism includes two symmetrically arranged guiding blocks 8. Inside one side of the sealing plate 4, there are two symmetrically arranged guiding grooves. Both guiding blocks 8 are fixedly connected to the spinneret plate 1 and respectively slide through the two guiding grooves. A guiding spring 9 is fixedly arranged between the guiding block 8 and the inner wall of the guiding groove.

[0033] When the push rod 7 pushes the fixed rod 5, through the sliding fit between the two guiding blocks 8 and the two guiding grooves, the sealing plate 4 can slide directionally when being pushed and compress the guiding spring 9. And through the elastic recovery of the guiding spring 9, the sealing plate 4 can move back, facilitating the effective utilization of the spinneret holes 2 inside the spinneret plate 1.

[0034] Embodiment 3

[0035] On the basis of Embodiment 1, in Embodiment 3, in order to fix the position of the rotating ring 6 after the rotating ring 6 rotates and the position of the sealing plate 4 is adjusted to ensure stable spinning, as Figure 3 shown, a groove is formed in the pipe wall of the internal thread installation pipe 3. A support rod 10 is fixedly arranged on the inner wall of the groove. A positioning plate 11 is rotatably sleeved on the rod wall of the support rod 10. The positioning plate 11 is arranged in an L shape. Both ends of the rod wall of the support rod 10 are sleeved with torsion springs 12. The two ends of the torsion spring 12 are respectively fixedly connected to the support rod 10 and the positioning plate 11. A plurality of circumferentially symmetrically arranged positioning grooves 13 are formed on the outer wall of the rotating ring 6. The end of the positioning plate 11 is inserted into the positioning groove 13. A pull ring 14 is fixedly arranged on the outer wall of the positioning plate 11.

[0036] Before pushing the sealing plate 4, the positioning plate 11 can be pulled through the pull ring 14, so that the positioning plate 11 rotates around the support rod 10 and twists the torsion spring 12 at the same time. At this time, the positioning plate 11 is separated from the positioning groove 13, enabling the rotating ring 6 to drive the push rod 7 to rotate and cooperate with the fixed rod 5 to push the sealing plate 4. When the position of the sealing plate 4 is determined, the pull ring 14 is released. Through the torque recovery of the torsion spring 12, the positioning plate 11 quickly rebounds and is inserted into the positioning groove 13. At this time, the positions of the rotating ring 6 and the push rod 7 are fixed, and then the position of the sealing plate 4 can be determined in cooperation with the elastic force of the guiding spring 9 to ensure the stability during the spinning process.

[0037] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
