Description
Technical Field
[0001] This utility model relates to the field of textile dyeing technology, specifically to a yarn separating mechanism for a warp transfer machine. Background Technology
[0002] Traditional yarn dyeing processes have low dye utilization rates, generate a large amount of waste, are resource-intensive, and cause air pollution, which is detrimental to environmental protection. To address this, the textile industry has developed warp transfer printing equipment, drawing inspiration from fabric printing transfer technology, which allows for dyeing without water. The warp transfer printing equipment is located at the front end of the textile machine; after the warp yarns are dyed through the equipment, they are fed into the machine to be woven into fabric with the weft yarns.
[0003] For fabrics with high warp density, the spacing between two warp yarns is less than 0.04 mm (for example, if the diameter of each warp yarn is 0.186 mm, and 8192 warp yarns need to be evenly distributed over a length of 1800 mm, the average is 4.55 yarns / mm. However, 4.55 warp yarns arranged compactly is 0.8463 mm, and the average spacing between each warp yarn is only 0.0337 mm). In this case, the traditional method of directly using a yarn separating mechanism cannot achieve a uniform distribution of yarns, which will still lead to color differences such as white showing, uneven center, uneven color, and vertical stripes in plain weave fabrics during the dyeing and printing process. Utility Model Content
[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a yarn separating mechanism for a warp transfer machine to improve the uniformity of warp yarn arrangement.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A yarn separating mechanism for a warp transfer machine includes a yarn separating bracket, a first yarn roller, two first guide rollers, a second yarn roller, a yarn separating roller, and a first yarn separating unit. The yarn separating bracket defines an installation space, and the first yarn roller, the first guide roller, the second yarn roller, and the yarn separating roller are arranged sequentially in the installation space along the warp yarn direction.
[0007] The warp yarn introduced by the first yarn roller is divided into a first warp yarn and a second warp yarn. The first warp yarn is led out from the second yarn roller after passing through one of the first guide rollers, and the second warp yarn is led out from the second yarn roller after passing through another of the first guide rollers. The first warp yarn and the second warp yarn led out by the second yarn roller are led out from both sides of the spacer roller, respectively.
[0008] The first yarn separating unit includes two yarn separating steel buckles and at least two yarn separating rollers. The yarn separating steel buckles are disposed between the first yarn roller and the first guide roller or between the second yarn roller and the first guide roller, and are used to separate the first warp yarn or the second warp yarn into multiple yarn bundles arranged at equal intervals. The yarn separating rollers are disposed between the second yarn roller and the first guide roller or between the first yarn roller and the first guide roller. After the first warp yarn and the second warp yarn pass through the yarn separating rollers, they are twisted into upper and lower yarn bundles. The two yarn bundles merge into one layer at the first guide roller or the second yarn roller.
[0009] The yarn separating mechanism further includes two second guide rollers, which are disposed between the second yarn roller and the first guide roller; a first region is formed between the two first guide rollers and the first yarn roller; a third region is formed between the two second guide rollers and the second yarn roller; and a second region is formed between the first guide roller and the second guide roller. The first warp yarn and the second yarn pass through the first guide roller and the second guide roller in sequence and are then led out from the second yarn roller.
[0010] The first region and / or the second region are provided with at least one yarn separating roller group, and each yarn separating roller group includes two yarn separating rollers arranged side by side; the third region is provided with two yarn separating steel buckles arranged side by side.
[0011] The two yarn-separating steel buckles are arranged in the first region and / or the second region; the third region is provided with at least one yarn-separating roller group, each yarn-separating roller group including two yarn-separating rollers arranged side by side.
[0012] The yarn separating mechanism further includes a second yarn separating unit disposed within the installation space, the second yarn separating unit being disposed between the second yarn roller and the yarn separating roller;
[0013] The second yarn separating unit includes a yarn separating steel buckle and at least one yarn separating roller group arranged sequentially along the warp yarn direction. The yarn separating roller group includes two yarn separating rollers. The first warp yarn and the second warp yarn led out through the second yarn roller pass through the yarn separating steel buckle and then pass through the two yarn separating rollers of the yarn separating roller group, and are led out through both sides of the yarn separating roller.
[0014] The yarn separating roller has evenly distributed equidistant thread grooves, which are used to separate the first warp yarn and the second warp yarn.
[0015] The yarn separating steel buckle includes a fixing strip and a plurality of steel buckle bodies spaced apart along the length of the fixing strip, with a guide gap formed between adjacent steel buckle bodies for guiding the first warp yarn or the second warp yarn.
[0016] By adopting the above scheme, this invention divides the warp yarns introduced by the first yarn roller into two groups. Then, a yarn separating steel clip and a yarn separating roller are used to separate and twist each group of warp yarns. Finally, a yarn separator roller is used to evenly fix the yarn direction, and the two groups of warp yarns are fed into a special warp yarn machine for dyeing. This invention divides the high-density warp yarns into two groups for processing, so that each group of warp yarns can be effectively separated and twisted, effectively improving the uniformity of the warp yarn arrangement.

[0034] Example 1
[0035] like Figure 1 As shown, this utility model discloses a yarn separating mechanism for a warp transfer machine, which includes a yarn separating bracket 10, a first yarn roller 21, two first guide rollers (31, 32), a second yarn roller 22, a yarn separating roller 40, and a first yarn separating unit. The yarn separating bracket 10 defines an installation space, and the first yarn roller 21, the first guide rollers (31, 32), the second yarn roller 22, and the yarn separating roller 40 are sequentially arranged within the installation space along the warp yarn direction. The first yarn separating unit is located between the first yarn roller 21 and the second yarn roller 22.
[0036] In this embodiment, the first yarn roller 21, the first guide rollers (31, 32) and the second yarn roller 22 are arranged from top to bottom, and the two first guide rollers (31, 32) are the left first guide roller 31 and the right first guide roller 32.
[0037] The first yarn separating unit includes two yarn separating steel clips 60 and at least two yarn separating rollers 50. The yarn separating steel clips 60 are positioned between the first yarn roller 21 and the first guide rollers (31, 32) or between the second yarn roller 22 and the first guide rollers (31, 32). The yarn separating rollers 50 are positioned between the second yarn roller 22 and the first guide rollers (31, 32) or between the first yarn roller 21 and the first guide rollers (31, 32). After the warp yarn passes through the yarn separating rollers 50, it is split into upper and lower yarn bundles, which then merge into one layer at the first guide rollers (31, 32) or the second yarn roller 22. When the yarn separating steel clips 60 are positioned between the first guide rollers (31, 32) and the first yarn roller 21, and the yarn separating rollers 50 are positioned between the first guide rollers (31, 32) and the second yarn roller 22, it indicates that the warp yarn is first processed by the yarn separating steel clips 60 and then split by the yarn separating rollers 50. When the yarn separating roller 50 is positioned between the first guide rollers (31, 32) and the first yarn roller 21, and the yarn separating steel buckle 60 is positioned between the first guide rollers (31, 32) and the second yarn roller 22, it indicates that the warp yarns first pass through the yarn separating roller 50 for splitting and then are processed by the yarn separating steel buckle 60. The specific positions of the yarn separating steel buckle 60 and the yarn separating roller 50 can be determined according to actual usage requirements.
[0038] like Figure 2 and Figure 3As shown, the yarn separating roller 50 has evenly distributed equidistant thread grooves 501, which are used to separate and twist the warp yarns. The yarn separating steel buckle 60 includes a fixing strip 601 and a plurality of steel buckle bodies 602 spaced apart along the length of the fixing strip 601. A guide gap 603 is formed between adjacent steel buckle bodies 602 to guide the warp yarns, thus dividing the warp yarns into a plurality of equally spaced yarn bundles.
[0039] In this embodiment, the first yarn separating unit includes two yarn separating steel clips 60 and two yarn separating rollers 50. The two yarn separating rollers are disposed between the first yarn roller 21 and the first guide rollers (31, 32), and the two yarn separating rollers 50 are the left yarn separating roller 51 and the right yarn separating roller 52. The two yarn separating steel clips 60 are disposed between the second yarn roller 22 and the first guide rollers (31, 32), and the two yarn separating steel clips 60 are the first yarn separating steel clip 61 and the second yarn separating steel clip 62.
[0040] After passing through the first yarn roller 21, the warp yarn is split into two, forming a first warp yarn 71 and a second warp yarn 72. The first warp yarn 71 is divided into two layers of yarn bundles, which are then separated and twisted by both sides of the left yarn separating roller 51. After being separated and twisted, the two layers of yarn bundles merge into one layer at the left first guide roller 31. The merged first warp yarn 71 then passes through the first yarn separating steel buckle 61, which separates it into multiple yarn bundles with equal spacing before being led out by the second yarn roller 22. Similarly, the second warp yarn 72 is divided into two layers of yarn bundles, which are then separated and twisted by both sides of the right yarn separating roller 52. After being separated and twisted, the two layers of yarn bundles merge into one layer at the right first guide roller 32. The merged second warp yarn 72 then passes through the second yarn separating steel buckle 62, which separates it into multiple yarn bundles with equal spacing before being led out by the second yarn roller 22. Finally, the first warp 71 and the second warp 72, which are led out by the second yarn roller 22, are led out by the two sides of the yarn separator roller 40 and enter the warp transfer machine for dyeing.
[0041] Example 2
[0042] like Figure 4 As shown, this second embodiment adds two second guide rollers (33, 34) to the first embodiment. These two second guide rollers (33, 34) are positioned between the second yarn roller 22 and the first guide rollers (31, 32). A first region is formed between the two first guide rollers (31, 32) and the first yarn roller 21; a second region is formed between the two first guide rollers (31, 32) and the two second guide rollers (33, 34); and a third region is formed between the two second guide rollers (33, 34) and the second yarn roller 22. The first warp yarn 71 and the second warp yarn 72 pass sequentially through the first guide rollers (31, 32) and the second guide rollers (33, 34) before exiting from the second yarn roller 22. The two second guide rollers (33, 34) are the left second guide roller 33 and the right second guide roller 34.
[0043] If the first warp yarn 71 and the second warp yarn 72 are first processed by the yarn separating roller 50 and then by the yarn separating steel buckle 60, then the first region and / or the second region shall have at least one yarn separating roller group, each yarn separating roller group including two yarn separating rollers 50 arranged side by side; the third region shall have two yarn separating steel buckles 60 arranged side by side. Figure 5 As shown, in this embodiment, the yarn separating roller group is located in the second region, and the second region has a total of 3 yarn separating rollers, for a total of 6 yarn separating rollers. Among them, three yarn separating rollers are the left yarn separating rollers 51, and the other three yarn separating rollers are the right yarn separating rollers 52. The two yarn separating steel buckles are the first yarn separating steel buckle 61 and the second yarn separating steel buckle 62.
[0044] After passing through the first yarn roller 21, the warp yarn is divided into the first warp yarn 71 and the second warp yarn 72.
[0045] The first warp yarn 71 first passes through the first guide roller 31 on the left, and then passes through the three right-side yarn splitting rollers 52 in sequence for splitting and yarn separation. After splitting and yarn separation, the first warp yarn 71 first passes through the second guide roller 34 on the right, and then passes through the second yarn splitting steel buckle 62. Under the action of the second yarn splitting steel buckle 62, the first warp yarn 71 is divided into multiple yarn bundles with equal spacing and then led out by the second yarn roller 22.
[0046] Similarly, the second warp yarn 72 first passes through the first guide roller 32 on the right side, and then passes through the three left yarn splitting rollers 51 in sequence for splitting and yarn separation. After splitting and yarn separation, the second warp yarn 72 first passes through the second guide roller 33 on the left side, and then passes through the first yarn splitting steel buckle 61. Under the action of the first yarn splitting steel buckle 61, the second warp yarn 72 is divided into multiple yarn bundles with equal spacing and then led out by the second yarn roller 22.
[0047] The first warp yarn 71 and the second warp yarn 72, which are drawn from the second yarn roller 22, are drawn from the upper and lower sides of the yarn separator roller 40, respectively, and then enter the subsequent warp transfer machine for dyeing.
[0048] If the first warp yarn 71 and the second warp yarn 72 are first processed by the yarn separating steel buckle 60 and then by the yarn separating roller 50, then the two yarn separating steel buckles 60 are set in the first region and / or the second region (the two yarn separating steel buckles 60 can be set in the first region simultaneously, or in the second region simultaneously, or in the first region and the second region respectively); the third region is provided with at least one yarn separating roller group, and each yarn separating roller group includes two yarn separating rollers 50 arranged side by side. Figure 6 As shown, in this embodiment, the first yarn-separating steel buckle 61 is disposed in the first region, and the second yarn-separating steel buckle 62 is disposed in the second region. The third region is provided with two yarn-separating roller groups, for a total of four yarn-separating rollers, of which two are left-side yarn-separating rollers 51 and the other two are right-side yarn-separating rollers 52.
[0049] After passing through the first yarn roller 21, the warp yarn is divided into the first warp yarn 71 and the second warp yarn 72.
[0050] The first warp yarn 71 passes through the first yarn splitting steel buckle 61, and the first warp yarn 71 is divided into multiple yarn bundles with equal spacing under the action of the first yarn splitting steel buckle 61; then the first warp yarn 71 passes through the left first guide roller 31 and the right second guide roller 34 in sequence, and then passes through the two right yarn splitting rollers 52 in sequence for splitting and yarn separation. After splitting and yarn separation, the first warp yarn 71 is led out by the second yarn roller 22.
[0051] Similarly, the second warp yarn 72 first passes through the first guide roller 32 on the right side, and then passes through the second yarn splitting steel buckle 62. Under the action of the second yarn splitting steel buckle 62, the second warp yarn 72 is divided into multiple yarn bundles with equal spacing. Then the second warp yarn 72 passes through the second guide roller 33 on the left side in sequence, and then passes through the two left yarn splitting rollers 51 in sequence for splitting and yarn separation. After splitting and yarn separation, the second warp yarn 72 is led out by the second yarn roller 22.
[0052] The first warp yarn 71 and the second warp yarn 72, which are drawn from the second yarn roller 22, are drawn from the upper and lower sides of the yarn separator roller 40, respectively, and then enter the subsequent warp transfer machine for dyeing.
[0053] Example 3
[0054] like Figure 7-9 As shown, based on the above embodiments one and two, this embodiment adds a second yarn separating unit. The second yarn separating unit is disposed within the installation space and located between the second yarn roller 22 and the yarn separating roller 40. The second yarn separating unit includes a yarn separating steel buckle 60 and at least one yarn separating roller group arranged sequentially along the warp yarn direction. The yarn separating roller group includes two yarn separating rollers 50. The first warp yarn 71 and the second warp yarn 72, which are led out through the second yarn roller 22, pass through the yarn separating steel buckle 60 and then pass through the two yarn separating rollers 50 of the yarn separating roller group, and are led out through both sides of the yarn separating roller.
[0055] Specifically, the second yarn separating unit in this embodiment includes a yarn separating steel buckle (hereinafter referred to as the third yarn separating steel buckle 63) and two yarn separating roller groups, totaling four yarn separating rollers 50. Two of these yarn separating rollers 50 are upper yarn separating rollers 53, and the other two are lower yarn separating rollers 54. The first warp yarn 71 (or the second warp yarn 72) led out via the second yarn roller 22 passes sequentially through the third yarn separating steel buckle 63 and the two lower yarn separating rollers 54, and is finally led out via the lower surface of the yarn separating roller 40. The second warp yarn 72 (or the first warp yarn 71) led out via the second yarn roller 22 passes sequentially through the third yarn separating steel buckle 63 and the two upper yarn separating rollers 53, and is finally led out via the upper surface of the yarn separating roller 40. The first warp yarn 71 and the second warp yarn 72 led out by the yarn separating roller 40 enter the warp transfer machine for dyeing.
[0056] In summary, the key to this invention lies in its method of dividing the warp yarns introduced by the first yarn roller 21 into two groups. Then, a yarn separating steel clip 60 and a yarn separating roller 50 are used to separately separate and twist each group of warp yarns. Finally, a yarn separator roller 40 evenly fixes the yarn direction, and the two groups of warp yarns are fed into a dedicated warp yarn dyeing machine. This invention divides high-density warp yarns into two groups for processing, ensuring that each group of warp yarns is effectively separated and twisted, thus significantly improving the uniformity of the warp yarn arrangement.
[0057] The above description is merely an embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
