[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] See also Figure 1-7 A method and system for producing linen-like and wool-like nylon fibers, comprising the following steps:

[0037] S1. Raw material configuration: Select nylon 6 POY raw yarn with a breaking elongation of 50%-60%, including a first POY yarn (60d / 48f), a second POY yarn (25d / 24f) and a cotton fiber yarn (75d / 48f);

[0038] S2. Differentiated processing:

[0039] a. The first POY yarn is sequentially drawn by rollers (draft ratio 1.01-1.1) and heated in a hot box (180-235°C);

[0040] b. The second POY yarn is directly delivered through the yarn guide without being drawn and treated with a hot box;

[0041] S3. Compounding: The first POY yarn of step (S2-a), the untreated second POY yarn of step (S2-b), and the environmentally friendly regenerated polyester fiber filament are formed into a plied yarn through a plying machine 1.

[0042] In the production process of nylon fiber, it is usually necessary to combine multiple strands of spun yarn and twist the strands after combining. There are usually two existing methods of combining and twisting. The first is to separate the combining and twisting, combining first and then twisting. In this case, the three different spun yarns are directly wound on the winding wheel, and then the winding wheel is moved to the twisting machine for twisting. However, this method requires the use of multiple devices, which is more troublesome to operate and occupies a large space. The second method is to rotate the three unwound spun yarns while unwinding, so that the winding wheel rotates the unwinding disk while winding and twisting. However, in this method of combining and twisting, the multiple strands released from the unwinding disk are twisted after leaving the unwinding disk, making it difficult to apply oil to the single strand to improve the surface cleanliness.

[0043] Therefore, in another embodiment of the present invention, further comprising:

[0044] Servo motor 4;

[0045] A plying tube 61, which is used to constrain and ply a plurality of textile yarns;

[0046] The winding frame 51 is disposed above the stranding machine 1 and is rotatably mounted on the top of the stranding tube 61. A winding wheel 55 is disposed within the winding frame 51. The winding wheel 55 slides and rotates along its own axis as the winding frame 51 rotates.

[0047] The stranding tube 61 and the servo motor 4 are fixedly mounted on the stranding machine 1, and the output end of the servo motor 4 is fixedly connected to the winding frame 51. The stranding machine 1 is fixedly mounted with a reel 3 for placing fiber bundles, etc., and a control console 2 is fixedly mounted on the stranding machine 1.

[0048] When the strands are twisted, the unwinding disk 3 unwinds the wire harness, and the servo motor 4 drives the winding frame 51 to rotate, so that the winding wheel 55 is wound. While the winding frame 51 is rotating, the multi-strand wire harness wound by the winding wheel 55 will be twisted between the stranding tube 61 and the positioning frame 510, and the single-strand wire harness located at the front end of the stranding tube 61 can still be independently oiled and other operations.

[0049] In another embodiment of the present invention, a first restraining rod 52 and a second restraining rod 56 are rotatably mounted on both ends of a winding frame 51, and a telescopic rod 53 is slidably mounted inside the first restraining rod 52 along its axial direction. A first connecting plate 54 is fixedly mounted on one end of the telescopic rod 53 located inside the winding frame 51.

[0050] A limiting rod 59 is installed inside the second restraining rod 56 along its axial direction, and a second connecting plate 57 is fixedly installed on one end of the limiting rod 59 located inside the winding frame 51;

[0051] The winding wheel 55 is disposed between the first connecting plate 54 and the second connecting plate 57 , and the winding wheel 55 is fixedly connected to the first connecting plate 54 and the second connecting plate 57 by screws or other detachable means.

[0052] In another embodiment of the present invention, further comprising:

[0053] A friction ring 71 is disposed on the periphery of the winding frame 51 , and the first restraining rod 52 is in contact with the friction ring 71 ;

[0054] When the servo motor 4 drives the winding frame 51 to rotate, the first constraint rod 52 and the friction ring 71 are in contact with each other. As the winding frame 51 rotates, the first constraint rod 52 will rotate on the surface of the friction ring 71. At this time, the rotation of the first constraint rod 52 will drive the first connecting disk 54 and the winding wheel 55 to rotate through the telescopic rod 53. At this time, the winding wheel 55 will rotate to reel in the fiber line extending from the upper end of the stranding tube 61. The diameter of the second constraint rod 56 is smaller than that of the first constraint rod 52, so that a certain distance is maintained between the second constraint rod 56 and the friction ring 71 when the first constraint rod 52 is in contact with the friction ring 71.

[0055] A vertical rod is fixedly mounted on the friction ring 71 , and the friction ring 71 is fixedly mounted above the stranding machine 1 via the vertical rod.

[0056] In another embodiment of the present invention, an outer ring 72 is fixedly mounted on the friction ring 71, and an arc-shaped displacement plate 73 is fixedly mounted on the inner wall of the outer ring 72;

[0057] A sphere 531 is fixedly mounted on the telescopic rod 53, and a spring 58 is fixedly mounted between the second connecting plate 57 and the second restraining rod 56;

[0058] The outer ring 72 is vertically arranged, and two displacement plates 73 are provided. The two displacement plates 73 are symmetrically arranged. Figure 4When the winding wheel 55 is installed between the two connecting disks, the spring 58 will push the winding wheel 55 to move to the left until the ball 531 contacts the left side of the displacement plate 73. The displacement plate 73 gradually increases in thickness from left to right. Therefore, when the ball 531 contacts the left side of the displacement plate 73, the winding wheel 55 will be located inside the winding frame 51 near the first constraint rod 52. When the servo motor 4 drives the winding frame 51 to rotate, the winding frame 51 rotates counterclockwise, and the first constraint rod 52 moves on the surface of the friction ring 71, thereby rotating to drive the winding wheel. 55 rotates and reels, and at the same time, the ball 531 will also rotate along the inner wall of the outer ring 72. At this time, the ball 531 will continue to approach the right side of the displacement plate 73, and the thickness of the displacement plate 73 will gradually increase. At this time, the ball 531 will push the telescopic rod 53 to move toward the inside of the winding frame 51. At this time, the telescopic rod 53 will drive the first connecting disk 54 to push the winding wheel 55 to move toward the direction of the second constraint rod 56, thereby compressing the spring 58. At this time, the winding wheel 55 will also move axially while rotating and reeling, so that the wound wire harness can be evenly reeled on its surface.

[0059] In another embodiment of the present invention: a positioning frame 510 is fixedly installed on the inner wall of the winding frame 51, and a circular hole is provided at the middle end of the positioning frame 510;

[0060] The circular hole is set just above the stranding tube 61. The wire bundle passing through the stranding tube 61 will pass through the circular hole again to be wound on the winding wheel 55. The circular hole ensures that the wire bundle will not be significantly offset from the stranding machine 1 when it is wound on the winding wheel 55.

[0061] In another embodiment of the present invention: a through hole 62 is provided on the joint pipe 61, and the longitudinal section of the through hole 62 is plum blossom-shaped;

[0062] In the present application, there are three strands of wire bundles, and therefore they correspond to plum blossom-shaped through holes 62. The plum blossom-shaped through holes 62 are formed by partially overlapping three circular holes. Therefore, when the three wire bundles pass through the through holes 62, they can pass through the three circular holes of the plum blossom-shaped through holes 62 one by one. When the winding frame 51 rotates, the wire bundles wound on the winding wheel 55 will pass through the circular holes so that the part of the wire bundles between the through holes 62 remains in a vertical state. At this time, when the winding frame 51 rotates, it will drive the three wire bundles to be twisted with each other in the vertical direction, and the plum blossom-shaped through holes 62 enable the three wire bundles to remain independent when passing through the stranded tube 61, so that they can be wound in sequence in the subsequent winding process without excessive winding.

[0063] In another embodiment of the present invention: the joint pipe 61 is provided with a bending portion;

[0064] When the wire harness passes through the inside of the combined tube 61, since the combined tube 61 is provided with a bending portion, the bending portion squeezes the wire harness, thereby increasing the friction force on the wire harness. At the same time, since the winding wheel 55 above is pulling the wire harness upward, it will ensure that the wire harness coming out of the upper end of the combined tube 61 and the winding wheel 55 are always kept taut and straightened without becoming loose.

[0065] In another embodiment of the present invention, a dividing hole 65 is formed on the combined pipe 61, and a dividing piece 63 is fixedly installed on the top of the inner wall of the dividing hole 65;

[0066] One end of the hair-dividing piece 63 close to the through hole 62 is arc-shaped to adapt to the curvature of the through hole 62. At the same time, the hair-dividing piece 63 is triangular in shape, and its tip is close to the through hole 62 and facing downward, and the tip is provided with a rounded corner. When the wire harness moves upward from the through hole 62, the tip of the hair-dividing piece 63 will squeeze most of the hairs, thereby making them gather inward. At the same time, the bent portion of the stranding tube 61 will also squeeze the hairs on the wire harness to make it more neat.

[0067] In another embodiment of the present invention: a dividing groove 64 is provided on the hair dividing piece 63;

[0068] Among them reference Figure 6 The dividing groove 64 becomes sharper and smaller in angle as it points downward. When a portion of hair that is long and severely spreads outward passes through the dividing piece 63, it will pass over the rounded corner and contact the dividing groove 64 due to its large spread angle and long length. However, since the bottom end of the dividing groove 64 has a small and sharp angle, the hair can be stuck in the sharp bottom end of the dividing groove 64 and thus separated from the yarn bundle, preventing the yarn bundle from carrying long hair with a large spread angle for plying and twisting, thereby improving the smoothness of the yarn bundle.

[0069] There are a plurality of separating pores 65 , and when hair is shed by the separating grooves 64 on the separating sheet 63 , the hair can be removed through the separating pores 65 .

[0070] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
