[0034] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0035] Refer to Figure 1 and Figure 2 For the first embodiment of the yarn separating device of the present utility model, it is used to separate a plurality of moving yarns 8. The yarn separating device includes a base 1, a yarn separating reed 2, a yarn separating rod 3, a yarn separating plate 4, a temperature control unit 5, a driving unit 6, and a control unit 7. In Figure 2 , only the yarn separating reed 2, the yarn separating rod 3 and the yarn separating plate 4 separating the yarn 8 are shown.

[0036] Refer to Figures 1 to 3 , the yarn separating reed 2 is disposed on the base 1 and includes a frame 21 defining a region 23, and a plurality of partition bars 22 disposed on the frame 21. The partition bars 22 are spaced along a first axial direction D1 and extend along a second axial direction D2 transverse to the first axial direction D1. The partition bars 22 divide the region 23 into a plurality of gaps 231, and the gaps 231 are for the yarn 8 to pass through at intervals. Specifically, the first axial direction D1 extends horizontally. The second axial direction D2 extends vertically, and each of the partition bars 22 is a steel wire.

[0037] Refer to Figure 1 , Figure 2 , and Figure 4 , the yarn separating rod 3 is disposed on the base 1 and is located downstream of the yarn separating reed 2 along the conveying direction of the yarn 8. The yarn separating rod 3 includes a rod body 31 that can rotate relative to the base 1 and extends along the first axial direction D1, two bearings 32 respectively disposed at two opposite ends of the rod body 31, and two shaft rods 33 respectively disposed on the bearings 32 and disposed on the base 1. Therefore, the rod body 31 can rotate relative to the base 1 through the bearings 32. The rod body 31 has an outer peripheral surface 311, and a plurality of annular grooves 312 formed on the outer peripheral surface 311 and spaced along the first axial direction D1. The annular grooves 312 are for the yarn 8 to be disposed at intervals. Each of the annular grooves 312 is jointly defined by two side groove surfaces 313 connected to the outer peripheral surface 311, and a lower arc surface 314 connected between the side groove surfaces 313 and having a concave surface facing upward. Each of the side groove surfaces 313 has a convex arc segment 3131 connected to the outer peripheral surface 311, and a side segment 3132 extending from a side of the convex arc segment 3131 opposite to the outer peripheral surface 311 along a radial direction perpendicular to the first axial direction D1 to the lower arc surface 314. That is to say, the side segments 3132 are generally parallel.

[0038] The number of the gaps 231 is greater than the number of the annular grooves 312. Therefore, the user can thread the yarn 8 through different positions of the gaps 231 according to appropriate width requirements, and then dispose the yarn 8 in the corresponding annular grooves 312 to make the yarn 8 extend in parallel. Moreover, when the yarn 8 is installed on the yarn separating rod 3, it can slide into the corresponding annular groove 312 along the convex arc segment 3131, and the setting is quite convenient.

[0039] Refer to Figure 1 、 Figure 2 and Figure 5 The yarn separating plate 4 is disposed on the base 1 and is located downstream of the yarn separating roller 3 along the conveying direction of the yarn 8. The yarn separating plate 4 includes a top surface 41 and a plurality of grooves 42 formed in the top surface 41 for the yarn 8 to be disposed at intervals. The grooves 42 extend along a third axial direction D3 intersecting the first axial direction D1 and the second axial direction D2 and are spaced along the first axial direction D1. Each of the grooves 42 is jointly defined by two side inclined surfaces 43 connected to the top surface 41 and a concave surface 44 connected between the side inclined surfaces 43 and facing upward. The side inclined surfaces 43 extend from the top surface 41 towards each other and gradually approach the concave surface 44. In other variant embodiments of the present embodiment, a plurality of perforations (not shown in the figure) respectively communicating with the grooves 42 may also be drilled in the yarn separating plate 4, and the perforations are adjacent to the downstream of the moving direction of the yarn 8. Therefore, the auxiliaries or solvents required before dyeing the yarn 8 can be respectively injected into the grooves 42, and the redundant auxiliaries or solvents can be extracted through the perforations by a negative pressure device (not shown in the figure).

[0040] The temperature control unit 5 includes a heating member 51 disposed on the yarn separating plate 4 for heating the yarn separating plate 4 and a temperature sensor 52 disposed on the yarn separating plate 4. The heating member 51 is an electric heating tube or an electric heating plate.

[0041] The driving unit 6 is disposed on the base 1 and is used to drive the roller body 31 of the yarn separating roller 3 to rotate. The driving unit 6 includes a transmission belt 61 wound around the roller body 31 of the yarn separating roller 3 and a motor 62 disposed on the base 1 and coupled to the transmission belt 61. The motor 62 is used to drive the transmission belt 61 to rotate, so that the transmission belt 61 drives the roller body 31 of the yarn separating roller 3 to rotate.

[0042] The control unit 7 is electrically connected to the heating member 51, the temperature sensor 52 and the motor 62. The control unit 7 can control the heating member 51 to heat the yarn separating plate 4 to a target temperature according to the temperature detected by the temperature sensor 52. The heated yarn separating plate 4 can heat the yarn 8 in the grooves 42, remove the moisture of the yarn 8 and make the yarn 8 dry and fluffy. The target temperature is about 35 to 80 degrees Celsius.

[0043] The control unit 7 can also receive a conveying speed. The conveying speed is the moving speed of the yarn 8. The control unit 7 can control the rotation speed of the motor 62 according to the conveying speed, so that the motor 62 drives the stick body 31 of the yarn-dividing stick 3 to rotate in accordance with the moving speed of the yarn 8, so that the tension of the yarn 8 remains stable and the risk of yarn breakage is reduced. The control unit 7 can receive the conveying speed from a sensor (not shown) arranged on a yarn-discharging roller (not shown) or a yarn-collecting roller (not shown). The yarn-discharging roller is located upstream of the yarn-dividing device and is used to output the yarn. The yarn-collecting roller is located downstream of the yarn-dividing device and is used to wind up the yarn. In this embodiment, the control unit 7 is a programmable logic controller (PLC).

[0044] See also Figure 6 , is a second embodiment of the yarn splitting device of the utility model, and the difference from the first embodiment is that the yarn splitting device includes a plurality of yarn splitting rollers 3 for winding the yarn 8. The driving unit 6 includes a plurality of transmission belts 61 wound between the yarn splitting rollers 3. The user can set the positions of the yarn splitting reed 2 and the yarn splitting plate 4 according to the required movement path of the yarn 8, and then set the position of the yarn splitting roller 3, so that the yarn 8 can change the moving direction in a neatly arranged state, so that the yarn 8 can maintain a stable tension and smoothly pass through the yarn splitting reed 2, the yarn splitting roller 3 and the yarn splitting plate 4.

[0045] See also Figure 7 , is a third embodiment of the yarn splitting device of the utility model, and the difference from the first embodiment is that the yarn splitting device further includes a yarn straightening unit 9 disposed between the yarn splitting reed 2 and the yarn splitting roller 3. The yarn straightening unit 9 is wavy and includes a plurality of yarn straightening plates 91 pivotally connected to each other. Each of the yarn straightening plates 91 has a base plate 911, and a plurality of yarn splitting needles 912 spaced apart on the base plate 911. The base plates 911 are pivotally connected to each other and disposed on a movable structure (not shown). The yarn splitting needles 912 define a plurality of gaps 913 for the yarn 8 to pass through. The base plate 911 can be moved through the movable structure to cause the yarn straightening unit 9 to extend and retract to change the spacing between the yarns 8. In this embodiment, the yarn straightening unit 9 extends to widen the spacing between the yarns 8.

[0046] In summary, the advantages of the yarn separating device of the present invention are described as follows.

[0047] First, the yarn 8 is separated by the slit 231 of the yarn reed 2, so that the position of the yarn 8 can be fixed to prevent the yarn 8 from being interlaced or overlapped. The yarn 8 is transported by the yarn separation roller 3 to prevent the yarn 8 from being worn due to friction with the roller body 31 of the yarn separation roller 3, so that the tension of the yarn 8 is kept stable to avoid the problem of fuzzing or yarn breakage.

[0048] II. When the yarn 8 output from the yarn splitting device enters a waterless dyeing device (not shown in the figure) for dyeing, by setting the temperature control unit 5 on the yarn splitting plate 4, heating the yarn 8 through the yarn splitting plate 4 can increase the heating area of the yarn 8 and remove the moisture on the yarn 8, making the yarn 8 dry and fluffy. When the dye is sprayed from the waterless dyeing device onto the yarn 8, it can be better absorbed, so as to increase the binding property between the yarn 8 and the dye. Therefore, by heating the yarn 8 with the yarn splitting plate 4 and the temperature control unit 5, the moisture on the yarn 8 can be removed, the humidity state of each yarn 8 entering the dyeing device can be normalized, and the dyeing quality can be improved.

[0049] III. Since the two side segments 3132 corresponding to each annular groove 312 are generally parallel, when the rod body 31 of the yarn splitting rod 3 rotates, the corresponding yarn 8 is not easily slipped out along the side segment 3132, so that the corresponding yarn 8 can stably move in the annular groove 312.

[0050] IV. By arranging a plurality of yarn splitting rods 3, the moving direction of the yarn 8 can be changed, and the turning angle of the movement of the yarn 8 can be 30 degrees, 45 degrees, 90 degrees, 180 degrees or 200 degrees, so that the yarn splitting device can be applicable to dyeing systems or weaving systems with different structures.

[0051] V. When the spacing of the yarns 8 from the yarn splitting reed 2 is too wide, too narrow or uneven, by adjusting the yarn arranging plate 91 of the yarn arranging unit 9, the spacing of the yarns 8 can be changed to correspond to the width of the yarn splitting rod 3 or the yarn splitting plate 4, so that the yarns 8 can pass through the yarn splitting rod 3 and the yarn splitting plate 4 in parallel and with an average spacing.

[0052] The above-described embodiments only represent three implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
