A guide rail is provided at the lower end of the translation motor, and the guide rail is slidably connected to the translation motor. A conveyor belt is provided below the guide rail. The clamping assembly is fixed to the translation motor. The clamping assembly includes a first clamping roller, a second clamping roller, a third servo motor, and a fourth servo motor. The first clamping roller is connected to the third servo motor, and the second clamping roller is connected to the fourth servo motor. This utility model can spread the produced green fiber in a continuous and regular fiber bundle form, thereby facilitating heat treatment of the green fiber and the winding operation after heat treatment, greatly improving the efficiency of fiber production.

[0003] In the fiber spinning process, after the fiber is extruded from the spinneret, it needs to be quickly cooled and solidified to maintain its shape and performance. However, in the actual production process, different types of fibers have different stretching ratios. When the fiber is stretched before twisting, if the cooling and solidification are too fast, it is easy to cause the fiber to be broken. If the cooling and solidification are too slow, it will affect the strength and stability of the fiber. Therefore, a fiber spinning and drawing device is needed that can adjust the cooling rate of the fiber before twisting according to the tensile properties of the fiber. Utility Model Content

[0004] The purpose of the utility model is to provide a fiber spinning traction device.

[0005] The technical problem solved by the utility model is to adjust the cooling rate before fiber twisting according to the tensile properties of different types of fibers, so as to adapt to the tensile requirements of different types of fibers and improve applicability and flexibility.

[0007] A further technical improvement of the present invention is that the outer peripheral wall of the wrapping roller is in contact with the outer peripheral wall of the cooling roller.

[0008] Furthermore, a pair of separating rollers are rotatably mounted on the mounting frame at positions corresponding to between the spinneret and the cooling roller. The separating rollers are used to separate multiple fibers ejected from the spinneret to prevent the multiple fibers from being entangled together.

[0009] Furthermore, an electric telescopic rod is fixedly installed at a position near the sliding bracket at the bottom of the mounting frame, and an output end of the electric telescopic rod is fixedly connected to one side of the sliding bracket.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This application changes the time required for the fiber to cool and coagulate before twisting by adjusting the distance between the focusing ring and the cooling roller, thereby changing the tensile deformation of the fiber to adapt to the tensile requirements of different types of fibers, thereby enhancing applicability and flexibility.

[0020] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0021] See also Figure 1-3 As shown, this embodiment provides a fiber spinning and drawing device, including a mounting frame 1, an extruder 2 is fixedly mounted on one side of the mounting frame 1, a spinneret 3 is fixedly mounted on one side of the extruder 2, a pair of separating rollers 4 are rotatably mounted on the mounting frame 1 at a position corresponding to the rear side of the spinneret 3, a cooling roller 5 is fixedly mounted on the mounting frame 1 at the rear side corresponding to the separating roller 4, a cooling system for keeping the cooling roller 5 in a cooling state is installed on the mounting frame 1, a sliding bracket 6 is slidably mounted on the rear side corresponding to the cooling roller 5 on the mounting frame 1, a focusing ring 7 is fixedly mounted on the top of the sliding bracket 6, an electric telescopic rod 8 for moving the sliding bracket 6 back and forth is fixedly mounted on the mounting frame 1, a winding roller 9 is rotatably mounted on the mounting frame 1 adjacent to the rear side of the sliding bracket 6, and a driving motor for causing the winding roller 9 to rotate is installed on the mounting frame 1;

[0022] The extruder 2 extrude fibers through the spinneret 3, and then pass the extruded fibers between a pair of separator rollers 4, which separate the extruded fibers. The fibers are then wrapped around the outer peripheral wall of the cooling roller 5. After being cooled and solidified by the cooling roller 5, the fibers are concentrated and passed through the concentrating ring 7. Finally, the concentrated fibers are wound around the winding roller 9, and the fibers are pulled by the rotation of the winding roller 9.

[0023] A ring 10 is rotatably mounted on the mounting frame 1 at a position between the sliding bracket 6 and the winding roller 9. The center of the ring 10 corresponds to the center of the central ring 7. A traction ring 11 is fixedly mounted on the inner peripheral wall of the ring 10. A gear ring 12 is fixedly mounted on the outer peripheral wall of the ring 10. A gear 13 meshing with the gear ring 12 is rotatably mounted on the mounting frame 1. A drive motor that causes the gear 13 to rotate is installed on the mounting frame 1.

[0024] By passing multiple fibers passing through the central ring 7 into the traction ring 11, and then the gear 13 drives the ring 10 to rotate through the ring gear 12, the rotating ring 10 drives the multiple fibers confined in the central ring 7 to rotate around the inner circumference of the ring 10 through the traction ring 11, so that the multiple fibers are twisted and entangled together to form a fiber bundle, thereby enhancing the strength and wear resistance of the fiber bundle;

[0025] Rotating plates 14 are rotatably mounted on both sides of the outer peripheral wall of the cooling roller 5, and a wrapping roller 15 is rotatably mounted between the two rotating plates 14. The outer peripheral wall of the wrapping roller 15 is in contact with the outer peripheral wall of the cooling roller 5. Push-pull plates 16 are rotatably mounted on the ends of the two rotating plates 14 away from the wrapping roller 15. The ends of the two push-pull plates 16 away from the rotating plates 14 are rotatably connected to the two sides of the sliding bracket 6 respectively.

[0026] Make multiple fibers pass between the cooling roller 5 and the wrapping roller 15. When the electric telescopic rod 8 drives the sliding bracket 6 away from the cooling roller 5, the sliding bracket 6 will drive the rotating plate 14 to rotate clockwise through the push-pull plate 16, so that the rotating plate 14 drives the wrapping roller 15 to rotate clockwise along the outer peripheral wall of the cooling roller 5. At this time, the wrapping roller 15 will gradually reduce the contact area of ​​the fiber on the outer peripheral wall of the cooling roller 5, and the cooling effect will be weakened. The sliding bracket 6 will drive the focusing ring 7 away from the cooling roller 5. By increasing the distance between the focusing ring 7 and the cooling roller 5, the fiber can be given more time to complete the crystallization and solidification process, and the fiber has more opportunities to stretch before twisting. Otherwise, the contact area between the fiber and the outer peripheral wall of the cooling roller 5 will gradually increase, the cooling effect will be enhanced, the focusing ring 7 will be close to the cooling roller 5, the time for the fiber to complete crystallization and solidification will be shortened, and the opportunity for the fiber to stretch will be reduced.

[0027] When the present invention is in use, the extruder 2 extrude multiple fibers through the spinneret 3, so that the multiple fibers pass through a pair of separation rollers 4 for separation, and then pass the separated multiple fibers between the wrapping roller 15 and the cooling roller 5. According to the characteristics of the fibers, the stretching requirements of the fibers are analyzed, and then the distance between the sliding bracket 6 and the cooling roller 5 is controlled by the electric telescopic rod 8 to adjust the distance between the focusing ring 7 and the cooling roller 5. When the distance between the focusing ring 7 and the cooling roller 5 increases, the wrapping roller 15 restricts the fibers to the outer peripheral wall of the cooling roller 5, and the contact area is reduced. The fibers have more time to complete crystallization and solidification. The multiple fibers have more time to be stretched before twisting, so that the fibers have greater tensile deformation, otherwise the tensile deformation of the fibers will be reduced. After passing through the focusing ring 7, the multiple fibers are driven by the traction ring 11 and twisted into a fiber bundle, thereby enhancing the strength and wear resistance of the fiber bundle. Finally, the fiber bundle is pulled by the rotating winding roller 9 and wound up on its outer peripheral wall to complete the spinning and traction of the fibers.
