Description

Technical Field

[0001] This invention relates to the field of textile technology, and more particularly to a yarn separating device. Background Technology

[0002] A three-dimensional cylindrical fabric loom is a machine used to weave cylindrical fabrics of a certain thickness. Since this machine requires a large amount of yarn and demands that the yarn be evenly distributed in a circular pattern, a yarn-separating mechanism is necessary. The yarn-separating mechanism is an important component of the three-dimensional cylindrical fabric loom, and its functions are: (1) to ensure that the yarn is evenly distributed on the circular reed before weaving; and (2) to prevent interference between the yarns during weaving, ensuring a clear yarn pattern. Most existing cylindrical fabric looms are single-layer structures and do not require a large amount of yarn. Their existing yarn-separating mechanisms cannot adequately solve the yarn-separation problem of the three-dimensional cylindrical fabric loom. Therefore, we need to research a new type of yarn-separating mechanism to meet these requirements. Summary of the Invention

The axis of each roller extends vertically, and each roller is rotatably mounted on the mounting frame about its axis. Each roller includes a main body and two limiting protrusions protruding from the upper and lower ends of the main body. A slot for inserting one of the heald frames is formed between the two limiting protrusions.

[0010] Optionally, the frame is provided with a slide groove that extends away from the coiling and tensioning mechanism, and the lower end of the lifting mechanism is provided with a sliding plate that slides with the slide groove. The lifting mechanism is slidably mounted on the slide groove via the sliding plate.

The ends of each yarn on multiple yarn loops are first manually passed through the multiple yarn separating holes on the yarn gathering mechanism to facilitate preliminary yarn combing. Then, through the heddle frame on the heddle lifting mechanism, the ends of each yarn are manually passed through the heddle eye on each heddle wire for fine yarn separation. The heddle eyes on the multiple independent heddle wires on the heddle frame constrain the multiple yarns, ensuring a uniform distribution of the yarns on the same plane. The ends of each yarn are then pulled to the curling and tightening mechanism, where they are manually and evenly fixed to the fixing structure on the reed plate. This ensures that the yarns are evenly arranged on the reed plate, meeting the yarn arrangement requirements of the next manufacturing process in a three-dimensional cylindrical fabric loom. This addresses the problem of existing yarn separating devices being unable to effectively separate yarns in three-dimensional cylindrical fabric looms when a large amount of yarn is required.

[0021] A three-dimensional cylindrical fabric loom is a machine used to weave cylindrical fabrics of a certain thickness. Since this machine requires a large amount of yarn and demands that the yarn be evenly distributed in a circular pattern, a yarn-separating mechanism is necessary. The yarn-separating mechanism is an important component of the three-dimensional cylindrical fabric loom, and its functions are: (1) to ensure that the yarn is evenly distributed on the circular reed before weaving; and (2) to prevent interference between the yarns during weaving, ensuring a clear yarn pattern. Most existing cylindrical fabric looms are single-layer structures and do not require a large amount of yarn. Their existing yarn-separating mechanisms cannot adequately solve the yarn-separation problem of the three-dimensional cylindrical fabric loom. Therefore, we need to research a new type of yarn-separating mechanism to meet these requirements.

[0022] To solve the above problems, the present invention provides a yarn separating device 100. Figure 1 This is a perspective view of an embodiment of the yarn separating device provided by the present invention; Figure 2 for Figure 1 A three-dimensional schematic diagram of the yarn gathering mechanism in the diagram; Figure 3 for Figure 1 A three-dimensional schematic diagram of the yarn gathering mechanism from another perspective; Figure 4 for Figure 3 Enlarged view of point A in the middle; Figure 5 for Figure 1 A three-dimensional schematic diagram of the lifting mechanism in the middle; Figure 6 for Figure 1 A three-dimensional schematic diagram of the coiling and tensioning mechanism in the middle; Figure 7 for Figure 6 A three-dimensional schematic diagram of the curled core mold structure in the diagram; Figure 8 for Figure 7 Enlarged view of point B in the middle; Figure 9 for Figure 1 A three-dimensional schematic diagram of part of the coiling and tensioning mechanism.

[0023] Please see Figure 1 The yarn separating device 100 includes a frame 10, a yarn gathering mechanism 20, a heddle lifting mechanism 30, and a curling and tensioning mechanism 40. The yarn gathering mechanism 20 is located on the frame 10 and includes a yarn separating section with multiple yarn separating holes for multiple yarns to pass through. The heddle lifting mechanism 30 is located on the frame 10 and includes a heddle frame 31 with multiple heddle wires and heddle eyes for a single yarn to pass through. The curling and tensioning mechanism 40 is located on the frame 10 and includes a reed plate 41 and a fixing structure on the reed plate 41 for fixing the beginning ends of each yarn.

[0024] In the technical solution provided by this invention, the yarn separating device 100 includes a yarn gathering mechanism 20, a heald lifting mechanism 30, and a curling and tensioning mechanism 40 disposed on the frame 10. The ends of each yarn on multiple yarn loops on the yarn bobbin are first manually passed through the multiple yarn separating holes on the yarn gathering mechanism 20 to facilitate preliminary manual combing of the yarn. Then, through the heald frame 31 on the heald lifting mechanism 30, the ends of each yarn are manually passed through the heald eye on each heald wire for fine yarn separation. Multiple independent heddles constrain multiple yarns, ensuring that the yarns are evenly distributed on the same plane. Then, the ends of each yarn are pulled to the crimping and tensioning mechanism 40, and the ends of each yarn are manually and evenly fixed to the fixing structure on the reed plate 41. This ensures that the yarns are evenly arranged on the reed plate 41, meeting the yarn arrangement requirements of the next manufacturing process of the three-dimensional cylindrical fabric loom. This solves the problem that the existing yarn separating device 100 cannot handle large quantities of yarn, thus better addressing the yarn separating issue of the three-dimensional cylindrical fabric loom.

[0025] Furthermore, in this embodiment, the curling and tensioning mechanism 40 is located in the middle of the frame 10; multiple yarn gathering mechanisms 20 and multiple heddle lifting mechanisms 30 are provided, with the multiple yarn gathering mechanisms 20 and multiple heddle lifting mechanisms 30 arranged circumferentially along the curling and tensioning mechanism 40, and each yarn gathering mechanism 20 located on the side of the heddle lifting mechanism 30 away from the curling and tensioning mechanism 40, and arranged one-to-one; the fixing structure includes multiple fixing parts 42 provided on the reed plate 41, the multiple fixing parts 42 arranged circumferentially along the reed plate 41, and each fixing part 42 corresponding to one heddle lifting mechanism 30. In this way, multiple yarn loops corresponding to the yarn separation needs can be set on the side of each yarn gathering mechanism 20 away from the heddle lifting mechanism 30, and more yarn loops are arranged around the periphery of the yarn separating device 100, which also facilitates yarn feeding from various directions, and finally evenly distributes multiple yarns on the circular reed plate 41.

[0026] Specifically, please refer to Figures 2 to 4 In this embodiment, the yarn separating section includes a first yarn separating section 21, which includes a first mounting frame 211, a plurality of horizontal bars 212, and a plurality of vertical bars 213. The first mounting frame 211 extends vertically. The plurality of horizontal bars 212 are installed within the first mounting frame 211, extending horizontally and spaced apart vertically. The plurality of vertical bars 213 are installed within the first mounting frame 211, extending vertically and spaced apart horizontally. A first gap is formed between two adjacent horizontal bars 212, and a second gap is formed between two adjacent vertical bars 213. The spaces corresponding to and communicating with the first gap and the second gap form the plurality of yarn separating holes. Thus, the yarn is initially separated into layers between the plurality of horizontal bars 212. Then, the yarn separated by the plurality of horizontal bars 212 is further sorted, thereby achieving preliminary yarn combing.

[0027] Further, please refer to Figures 2 to 4 In this embodiment, the yarn separating section further includes a second yarn separating section 22 located on the side of the first yarn separating section 21 near the heald frame mechanism 30. The second yarn separating section 22 includes a plurality of yarn separating rods 222 spaced vertically, with a yarn separating gap formed between each pair of adjacent yarn separating rods 222. Each yarn separating gap is used for passing through a portion of the yarn passing through the plurality of yarn separating holes. Thus, the first yarn separating section 21 first performs preliminary combing of the yarn, and the second yarn separating section 22 then separates the combed yarn into layers, facilitating subsequent yarn separating processing.

[0028] Specifically, the heald frame 30 is located above the yarn gathering mechanism 20; the second yarn separating section 22 includes a second mounting frame 221 and a plurality of yarn separating rods 222 mounted within the second mounting frame 221. The second mounting frame 221 and the plurality of yarn separating rods 222 are inclined from bottom to top in a direction away from the first yarn separating section 21. Thus, when the yarn passes through the plurality of second crossbars 212 of the second yarn separating section 22 from the outlet end of each of the yarn separating holes of the first yarn separating section 21 and travels towards the heald frame 30, the inclination of the upper end of the second mounting frame 221 towards the heald frame 30 reduces the angle of yarn bending, thereby mitigating friction and fuzzing during yarn curling and improving fabric quality.

[0029] Further, please refer to Figure 5 In this embodiment, multiple heald frames 31 are provided, and the heald lifting mechanism 30 further includes a mounting frame 32 and multiple positioning structures. The multiple positioning structures are arranged sequentially on the mounting frame 32 in the vertical direction, and each positioning structure is used to position a corresponding heald frame 31. Each positioning structure includes at least two rollers 33 arranged opposite each other in the horizontal direction. The axis of each roller 33 extends vertically, and each roller 33 is rotatably mounted on the mounting frame 32 around its axis. Each roller 33 includes a main body and two limiting protrusions protruding from the upper and lower ends of the main body. A slot for inserting the heald frame 31 is formed between the two limiting protrusions.

[0030] Thus, by setting more heald frames 31, more yarns can be separated through multiple heald frames 31. In specific installation, the edge of each heald frame 31 can be aligned with two slots arranged opposite each other in the horizontal direction, and then the heald frame 31 can be pushed in. The two slots can guide and limit the movement, so that the heald frame 31 can be positioned between the at least two rollers 33. In order to facilitate the installation of the heald frame 31, the rollers 33 can be rotated. When pushing the heald frame 31 to move, the sliding friction between the heald frame 31 and the rollers 33 can be converted into rolling friction, reducing frictional resistance.

[0031] Furthermore, since the operator needs to operate at the winding and tensioning mechanism 40 during the yarn threading process, to avoid interference from the heald lifting mechanism 30, please refer to [the relevant documentation / reference needed]. Figure 5In this embodiment, the frame 10 is provided with a sliding groove extending away from the coiling and tensioning mechanism 40. The lower end of the heddle-lifting mechanism 30 is provided with a sliding plate 34 that slidably engages with the sliding groove. The heddle-lifting mechanism 30 is slidably mounted on the sliding groove via the sliding plate 34. Thus, when operation near the coiling and tensioning mechanism 40 is required, the heddle-lifting mechanism 30 can be slid away from the coiling and tensioning mechanism 40. Furthermore, when laying the weft threads, the weft thread laying mechanism may interfere with the heddle-lifting mechanism 30; therefore, when the weft thread laying mechanism is working, the heddle-lifting mechanism 30 can also be slid away from the coiling and tensioning mechanism 40.

[0032] Specifically, since the textile process involves the interlacing of warp and weft yarns to form a fabric, to prevent yarn interference, please refer to [the relevant documentation / reference needed]. Figures 6 to 8 In this embodiment, the curling and tensioning mechanism 40 includes a curling core mold structure 43. The curling core mold structure 43 includes a partition 431, a reed 432, a driving device, and a constraint plate 433. The partition 431 includes a plurality of partition pieces 4311 extending vertically and spaced horizontally. The reed 432 includes a plurality of reed blades 4321 extending horizontally and spaced apart. A reed gap is formed between every two reed blades 4321, and a partition piece 4311 is disposed in each reed gap. The reed 432 is movably mounted on the frame 10 in the vertical direction; the drive device is mounted on the frame 10, and the drive device has a drive part that is movably arranged in the vertical direction. The drive part is connected to the reed 432 to drive the reed 432 to move up and down; the constraint plate 433 is mounted on the frame 10, and the constraint plate 433 extends in the horizontal direction. At one end near the plurality of segmented pieces 4311, a toothed part 4331 that is adapted to the plurality of segmented pieces 4311 is provided.

[0033] Thus, the yarn is guided upwards between the multiple dividing plates 4311. During the curling and tightening process, the constraint pressure plate can hold the bundled yarns at the edges of the multiple dividing plates 4311, preventing the yarns on the dividing plates 4311 from interfering with each other, which is beneficial to the curling movement of the yarns. The reed 432 is used to operate the weft yarn, while the multiple dividing plates 4311 in this embodiment are used to separate the warp yarns.

[0034] It should be noted that the driving device can be a cylinder, and the driving part is the cylinder rod of the cylinder. Of course, the driving device can also be other driving structures, and no specific limitations are made in this invention.

[0035] Specifically, please refer to Figure 9In this embodiment, the curling and tensioning mechanism 40 further includes a plurality of partition posts 44 disposed on the reed plate 41. The plurality of partition posts 44 are disposed around the plurality of fixing parts 42 and are spaced apart along the circumference of the reed plate 41. A space for yarn to pass through is formed between each pair of adjacent partition posts 44. It can be understood that the distance between each pair of adjacent partition posts 44 is equal, so that the space is consistent. In this way, the plurality of partition posts 44 evenly separate the final yarn, so that the yarn located between the fixing structure and the plurality of partition posts 44 can be evenly distributed radially.

[0036] Specifically, in this embodiment, each fixing part 42 includes a base 421 and a pressure block 422. The base 421 extends horizontally, and its upper end surface is provided with a groove extending horizontally. The lower end surface of the pressure block 422 is provided with a limiting protrusion that matches the groove. Thus, when the final bundled yarn enters the winding and tensioning mechanism 40 along the multiple dividing pieces 4311, the pressure block 422 presses the yarn onto the reed plate 41. During the winding process, the yarn is stretched to maintain a certain tension. The reed plate 41 is small in size and can fix many yarns, improving weaving efficiency. Therefore, this invention not only improves fabric quality and has a simple structure that saves significant costs, but also has high working efficiency.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made under the inventive concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
