Description

Technical Field

[0001] This utility model relates to the field of spinning production technology, and more specifically to a standardized device for winding nylon 6 yarn. Background Technology

[0002] In the winding and forming process of nylon 6 spinning, the multiple strands of raw yarn, after being drawn and heat-set by the first and second hot rollers, are separated into individual yarns. These yarns need to be precisely guided and separated before being wound onto their respective winding heads to form qualified yarn cakes. To ensure winding quality, such as uniform tension, good package formation, and no twisted or tangled yarns, and to improve production efficiency (especially the starting speed), a yarn separation guide point needs to be set on the yarn path after the first and second hot rollers and before the winding head.

[0003] Currently, the common practice in the industry is to simply place a transverse wire between the first and second hot rollers as a wire guide. Since the wire itself is a smooth cylindrical surface without fixed wire-separating points, operators need to manually "throw" or "wrap" the entire bundle of wire onto the wire during the initial winding process. The winding position, number of turns, and tightness depend on the operator's personal habits and skill level. Therefore, different employees, and even the same employee in different operations, will result in different initial distributions of the wire bundle on the wire. This leads to inconsistent starting points and spacing of the individual wires entering the winding head, which is a potential cause of subsequent winding tension fluctuations and poor forming. Summary of the Invention

[0004] To address the technical problems existing in the nylon 6 filament splitting technology, the first aspect of this utility model proposes a standardized device for nylon 6 winding yarn, comprising:

[0005] A wire splitting structure is installed at the wire path outlet of the first and second hot rollers;

[0006] The filament splitting structure includes a support structure and a filament splitting guide structure. The filament splitting guide structure is installed on the support structure, and the filament splitting guide structure is provided with multiple independent guide grooves, each of which is used to guide a single strand or a single bundle of nylon 6 filaments.

[0007] The guide groove is disposed on the outer wall of the wire splitting guide structure, and the inner wall of the guide groove is constructed as a ceramic layer with a smooth curved surface.

[0008] Preferably, the plurality of guide wire grooves are linearly distributed along the length direction of the support structure.

[0009] Preferably, the support structure includes a first plate and a second plate, the first plate and the second plate are perpendicular to each other and form an L-shape, and the wire guiding structure is connected to the second plate.

[0010] Preferably, the first plate has a pair of waist-shaped holes.

[0011] Preferably, the wire-splitting guide structure is a ceramic gourd, comprising multiple wire-splitting guide plates connected together, with a wire-guide groove formed between every two adjacent wire-splitting guide plates, wherein the wire-splitting guide plate located at the end is connected to a connecting screw, and the connecting screw is connected to a second plate body.

[0012] Preferably, the connecting screw can be adjusted in position relative to the second plate along its axial direction and is fixed by a pair of nuts.

[0013] Preferably, the diameter of the wire bundle passing through the guide groove is defined as d, and the width D of the guide groove satisfies d <D≤1.5d。

[0014] Preferably, the roughness Ra of the inner wall of the guide wire groove is ≤ 0.1 μm.

[0015] Preferably, the inlet and outlet of the guide wire groove are both configured with a flared curved surface.

[0016] Preferably, the wire-splitting guide plate is a ceramic structure.

[0017] Compared with existing technologies, this utility model proposes a standardized device for winding nylon 6 yarn. By replacing the iron wire with a yarn separating component with an independent guide groove, the ceramic guide groove can forcefully separate the yarn bundle, avoiding the randomness of yarn position caused by manual winding of iron wire. This lays the foundation for uniform tension and high-quality winding. By replacing winding with a separate device, the start-up time is shortened, and inconsistencies caused by differences in personnel operation are avoided. This helps to ensure the standardization of the yarn path and makes the quality of the final wound yarn cake highly consistent. Attached Figure Description

[0024] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0025] like Figure 1 and Figure 2 As shown, currently, the wires are separated at the wire outlets of the first hot roller 10 and the second hot roller 20 via iron wire 200. When starting the wires, the operator needs to manually "throw" or "wrap" the entire bundle of wires onto the iron wire. The position, number of turns, and tightness of the wrapping depend entirely on the operator's personal habits and skill level. Multiple strands of wire are prone to sliding and gathering on the smooth cylindrical surface of the iron wire, making it difficult to maintain a uniform spacing. Even if the initial position meets the requirements, it is easy to deviate due to tension fluctuations during operation. Different positions and different wrapping methods will result in different contact angles and wrap angles between each strand of wire and the iron wire, which in turn will result in different tensions and frictions for each strand of wire. Therefore, the wires are not uniformly separated, which is not conducive to the formation of consistent tension in subsequent winding.

[0026] Combination Figure 3 and Figure 4 As shown, the first aspect of this utility model proposes a standardization device for nylon 6 winding yarn, including a yarn splitting structure 300 disposed at the yarn outlet of the first hot roller 10 and the second hot roller 20.

[0027] The first hot roller 10 and the second hot roller 20 are both heating rollers, such as roller structures that are electrically powered or heated by a heat medium. In the heated state, they can stretch and shape the nylon filament bundles coated with oil, eliminate internal stress, stabilize the fiber structure, and reduce subsequent shrinkage.

[0028] like Figure 5 As shown, the filament splitting structure 300 includes a support structure 310 and a filament splitting guide structure 320. The filament splitting guide structure 320 is installed on the support structure 310, and the filament splitting guide structure 320 is provided with multiple independent guide grooves 301, each guide groove 301 being used to guide a single strand or a single bundle of nylon 6 filaments.

[0029] Thus, compared to the existing method of separating wires by wire, since the positions of the wire guide grooves 301 are fixed and precise, the wire guide grooves 301 can provide separation points for the wire bundle. The operator only needs to place each wire through the designated groove. When starting the new wire bundle, the wire bundle can be directly placed on the corresponding wire guide groove 301 to form a bundle. Moreover, each bundle does not interfere with each other after passing through the wire guide groove 301, preventing wires from bundling after passing through the wire. It can also ensure that different wire bundles maintain a relatively equal spacing and the same wire resistance, which is conducive to the formation of consistent tension in subsequent winding and eliminates the differences caused by manual winding.

[0030] As mentioned above, by modifying the splitting structure, the starting action is simplified from the original skill-based winding action to a mechanical threading action. This change makes the action simpler, clearer, and easier to master. Furthermore, the threading action is faster than repeatedly adjusting the winding speed, resulting in a higher success rate and avoiding rework caused by unsatisfactory winding.

[0031] The wire guide groove 301 is disposed on the surface of the wire splitting guide structure 320, and the inner wall of the wire guide groove 301 is constructed as a ceramic layer with a smooth curved surface.

[0032] Because ceramics have high surface hardness and a smooth surface, the coefficient of friction for nylon filaments is much lower than that for iron wire. This allows the filaments to slide smoothly in the guide groove 301, making them less prone to sticking due to tension changes. This reduces filament skipping caused by sudden changes in friction, helps maintain the uniformity of winding tension, and reduces the occurrence of thick and thin filaments and breakage due to tension differences.

[0033] As mentioned above, due to the uniformity of the yarn path, low friction during yarn passage, and stable tension, the final wound yarn cake exhibits high consistency in quality.

[0034] In an optional embodiment, the diameter of the wire bundle passing through the guide groove 301 is defined as d, and the width D of the guide groove 301 satisfies d <D≤1.5d。

[0035] Thus, the dimensions of the guide groove 301 serve to constrain and precisely limit the nylon 6 filament bundle.

[0036] Furthermore, the roughness Ra of the inner wall of the guide wire groove 301 is ≤ 0.1 μm. Preferably, both the inlet and outlet of the guide wire groove 301 are set as rounded corners or flared surfaces.

[0037] Thus, this structural design can effectively reduce the scratching or jamming of the filament bundle at the inlet or outlet, thereby reducing the generation of fuzz, improving the smoothness of threading the new filaments, and reducing the breakage rate.

[0038] In an optional embodiment, the wire splitting guide plate 321 is entirely made of ceramic. This ensures low friction and high durability for the wire splitting guide plate 321.

[0039] Preferably, the plurality of guide wire grooves 301 are linearly distributed along the length direction of the support structure 310. For example... Figure 5 As shown, the filament splitting guide structure 320 includes two adjacent filament splitting guide plates 321. This allows for the fulfillment of the requirement to divide the filament bundle into two parts.

[0040] Combination Figure 2 As shown, in the existing method of splitting wire 200, the wire bundle 100 forms two separate wire bundles 102 after passing through the splitting point 101. Since the spacing between the two separate wire bundles 102 relies entirely on the tension of the wire 200, it is unstable. Figure 4 As shown, the filament bundle 100 is guided by two filament guide plates 321 to form two independent filament bundles 102 with a predetermined spacing, and each filament bundle can maintain the same thread tension.

[0041] Combination Figure 5 As shown, in an optional embodiment, the support structure 310 includes a first plate 311 and a second plate 312, the first plate 311 and the second plate 312 are perpendicular to each other and form an L-shape, and the wire guiding structure 320 is connected to the second plate 312.

[0042] Furthermore, the first plate 311 is provided with a pair of oblong holes 313. In this way, the first plate 311 can be installed into a suitable position on the housing of the winding equipment by screws.

[0043] Furthermore, the wire-splitting guide structure 320 is a ceramic gourd, including multiple wire-splitting guide plates 321 connected together, with a wire-guide groove 301 formed between every two adjacent wire-splitting guide plates 321, wherein the wire-splitting guide plate 321 located at the end is connected to a connecting screw 322, and the connecting screw 322 is connected to the second plate 312.

[0044] The connecting screw 322 can be adjusted in position relative to the first plate 311 along its axial direction and is fixed by a pair of nuts 323.

[0045] Thus, by controlling the position of the connecting screw 322 and the second plate 312, the wire splitting guide plate 321 is placed in the appropriate position.

[0046] In conjunction with the above embodiments, this application replaces iron wire with a wire separating component with an independent wire guide groove. The ceramic wire guide groove can be used to forcibly separate the wire bundle, avoiding the randomness of the wire path position caused by manual winding of iron wire. This lays the foundation for uniform tension and high quality of subsequent winding. By replacing winding with wire bonding, the start-up time is shortened, and inconsistencies caused by differences in personnel operation are avoided. This helps to ensure the standardization of the wire path and makes the final wound wire cake of high quality.

[0047] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
