DETAILED DESCRIPTION

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

[0036] Please refer to Figures 1-7 A production method and production system for imitating wool and linen fibers, comprising the following steps:

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

[0038] S2, differential processing:

[0039] ​a. the first POY yarn is sequentially treated by roller drafting (drafting ratio 1.01-1.1), hot box heating (180-235 DEG C);

[0040] b. the second POY yarn is directly conveyed by a guide without drafting and hot box treatment;

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

[0042] In the production process of nylon fibers, it is usually necessary to ply multiple spinnings and twist the bundle after plying. The existing plying and twisting methods usually have two kinds. The first kind is to separate the plying and twisting, that is, to ply first and then twist. In this case, the plying is directly winding three different spinnings on the winding wheel, and then moving the winding wheel to the twisting machine for twisting. However, this method needs multiple devices to work together, which is more troublesome to operate, and the multiple devices also occupy a large space. The second kind is to rotate the three spinnings while unwinding, so that the winding wheel is wound while the rotation of the unwinding disc twists. However, in this method, the multiple bundles of yarns are twisted after leaving the unwinding disc, so it is difficult to perform oiling and other operations to improve the surface cleanliness of the single bundle of yarns.

[0043] Therefore, in another embodiment of the present application:

[0044] a servo motor 4;

[0045] a plying pipe 61 for restraining and plying a plurality of bundles of textile threads;

[0046] a winding frame 51 disposed above the plying machine 1 and rotatably mounted at the top end of the plying pipe 61, the inside of the winding frame 51 being provided with a winding wheel 55, and the winding wheel 55 sliding along its own axial direction while the winding frame 51 rotates and rotates;

[0047] wherein the plying pipe 61 and the servo motor 4 are fixedly installed on the plying machine 1, and the output end of the servo motor 4 is fixedly connected with the winding frame 51, wherein a winding disc 3 is fixedly installed on the plying machine 1 for placing fiber bundles, and a control console 2 is fixedly installed on the plying machine 1;

[0048] When plying and twisting, the winding disc 3 unwinds the bundle, and the servo motor 4 drives the rotation of the winding frame 51, so that the winding wheel 55 winds. While the winding frame 51 rotates, the multiple bundles of yarns wound by the winding wheel 55 are twisted between the plying pipe 61 and the positioning frame 510. The single bundle of yarns at the front end of the plying pipe 61 can still be independently oiled and operated.

[0049] In another embodiment of the present application: the two ends of the winding frame 51 are respectively rotatably installed with a first constraint rod 52 and a second constraint rod 56, and the inside of the first constraint rod 52 is slidably installed with an extension rod 53 along the axial direction, and the one end of the extension rod 53 inside the winding frame 51 is fixedly installed with a first connecting disc 54;

[0050] The inside of the second constraint rod 56 is slidably installed with a limiting rod 59 along the axial direction, and the one end of the limiting rod 59 inside the winding frame 51 is fixedly installed with a second connecting disc 57;

[0051] The winding wheel 55 is arranged between the first connecting disc 54 and the second connecting disc 57, and the winding wheel 55 is fixedly connected with the first connecting disc 54 and the second connecting disc 57 through screws or other detachable ways.

[0052] In another embodiment of the present application: it further comprises:

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

[0054] When the servo motor 4 drives the winding frame 51 to rotate, at this time, since the first constraint rod 52 is in contact with the friction ring 71, with the rotation of the winding frame 51, 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 disc 54 and the winding wheel 55 to rotate through the extension rod 53, at this time, the winding wheel 55 will rotate to wind, so as to wind the fiber line extending from the upper end of the plying pipe 61, wherein the diameter of the second constraint rod 56 is smaller than that of the first constraint rod 52, so that when the first constraint rod 52 is in contact with the friction ring 71, the second constraint rod 56 and the friction ring 71 maintain a certain spacing;

[0055] A vertical rod is fixedly installed on the friction ring 71, and the vertical rod is fixedly installed above the plying machine 1.

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

[0057] A spherical body 531 is fixedly installed on the extension rod 53, and a spring 58 is fixedly installed between the second connecting disc 57 and the second constraint rod 56;

[0058] The outer ring 72 is vertically arranged, and the displacement plate 73 is provided with two, and the two displacement plates 73 are symmetrically arranged, for example, Figure 4When the winding wheel 55 is installed between the two connecting plates, the spring 58 will push the winding wheel 55 to move to the left until the ball 531 contacts the left side of the variable position plate 73, and the thickness of the variable position plate 73 gradually increases from left to right, so that when the ball 531 contacts the left side of the variable position plate 73, the winding wheel 55 is located inside the winding frame 51 close to the first constraint rod 52, and when the servo motor 4 drives the winding frame 51 to rotate, the winding frame 51 rotates counterclockwise, the first constraint rod 52 moves on the surface of the friction ring 71 and rotates to drive the winding wheel 55 to rotate and wind, and at the same time, the ball 531 rotates along the inner wall of the outer ring 72, and the ball 531 constantly moves to the right of the variable position plate 73, and the thickness of the variable position plate 73 gradually increases, so that the ball 531 pushes the telescopic rod 53 to move to the inside of the winding frame 51, and the telescopic rod 53 drives the first connecting plate 54 to push the winding wheel 55 to move to the direction of the second constraint rod 56, so as to compress the spring 58, and at the same time, the winding wheel 55 rotates and winds, and also moves axially to make the winding wire evenly wound on the surface.

[0059] In another embodiment of the present application, the inner wall of the winding frame 51 is fixedly provided with a positioning frame 510, and the middle end of the positioning frame 510 is provided with a circular hole.

[0060] The circular hole is arranged directly above the plying pipe 61, and the wire passing through the plying pipe 61 passes through the circular hole again to be wound on the winding wheel 55, so that the wire does not deviate greatly between the plying machine 1 when being wound on the winding wheel 55.

[0061] In another embodiment of the present application, the plying pipe 61 is provided with a through hole 62, and the longitudinal section of the through hole 62 is plum blossom-shaped.

[0062] In the present application, the plying wire is three, so the plum blossom-shaped through hole 62 is formed by three circular holes partially overlapping together, so that when the three wires pass through the through hole 62, they can pass through the three circular holes of the plum blossom-shaped through hole 62 one by one, and when the winding frame 51 rotates, the wire wound on the winding wheel 55 passes through the circular hole to keep the part of the wire between the through hole 62 in a vertical state, and at the same time, the winding frame 51 rotates to drive the three wires to twist in the vertical direction, and the plum blossom-shaped through hole 62 makes the three wires keep independent state when passing through the plying pipe 61, so that the twisting process can be carried out in turn without over-twisting.

[0063] In another embodiment of the present application, the plying pipe 61 is provided with a bending part.

[0064] When the wire harness passes through the inside of the plying pipe 61, since the plying pipe 61 is provided with the bending part, when the wire harness passes through the bending part, the bending part of the wire harness causes an extrusion to the wire harness so as to increase the friction force suffered by the wire harness, and at the same time, since the winding of the upper winding wheel 55 is pulled on the wire harness, it will ensure that the wire harness coming out of the upper end of the plying pipe 61 and the winding wheel 55 always maintain a tight and straight state without loosening.

[0065] In another embodiment of the present application: the plying pipe 61 is provided with a hair separating hole 65, and the inner wall top end of the hair separating hole 65 is fixedly installed with a hair separating piece 63;

[0066] Wherein one end of the hair separating piece 63 close to the through hole 62 is arc-shaped to adapt to the curvature of the through hole 62, and the hair separating piece 63 is triangular in shape, and the tip thereof is close to the through hole 62 and is arranged 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 separating piece 63 will extrude most of the hair, so as to be bundled inward, and the bending part of the plying pipe 61 will also extrude the hair on the wire harness so as to be more neat.

[0067] In another embodiment of the present application: the hair separating piece 63 is provided with a separating groove 64;

[0068] Wherein referring to Figure 6 , the separating groove 64 is more sharp and the included angle is smaller as it goes downward, when there is a part of the hair which is longer and opens outward seriously, when it passes through the hair separating piece 63, since its opening angle is larger and the length is longer, it will pass the rounded corner and contact with the separating groove 64, and since the bottom end of the separating groove 64 is smaller and sharp, at this time, the hair can be stuck in the sharp bottom end of the separating groove 64, so as to be separated from the wire harness, avoiding the wire harness carrying the longer and larger opening angle hair to ply and twist, so as to improve the smoothness of the wire harness;

[0069] Wherein the hair separating hole 65 is provided with a plurality of holes, when the hair is separated by the separating groove 64 on the hair separating piece 63, it can be removed through the hair separating hole 65.

[0070] The above only describes certain exemplary embodiments of the present application by way of illustration, and it is not doubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above figures and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present application.
