Description

Technical Field

[0001] This utility model relates to the field of yarn processing technology, and in particular to a yarn feeding device for yarn processing. Background Technology

[0002] In the yarn processing industry, the yarn feeding device is one of the most crucial pieces of equipment. Through the coordinated operation of the yarn guide, yarn storage roller, transmission mechanism, and tension adjustment device, it stably conveys the yarn from the yarn storage roller to the knitting system, ensuring that the yarn participates in the loop-forming process with constant tension, appropriate speed, and continuous operation. This guarantees the uniformity of fabric quality, reduces the risk of yarn breakage, and adapts to the processing needs of different machine types (such as flat knitting machines and circular knitting machines) and yarn types (staple fiber yarn, chemical fiber filament, spandex core-spun yarn).

[0003] A Chinese utility model patent (publication number: CN220564833U) discloses a yarn feeding device, which achieves the limiting and fixing of the yarn bobbin through the cooperation of structures such as push-pull blocks, movable plates, limiting plates, functional cylinders, and push-pull blocks, effectively preventing the yarn bobbin from falling out of the equipment due to tension.

[0004] Although the yarn feeding device has achieved the function of limiting the yarn bobbin, its stability still needs to be improved in practical applications. It achieves the tensioning and limiting effect on the yarn bobbin through the friction between the inclined surface of the triangular block and the inclined surface of the extrusion block. However, during the yarn feeding process, the vibration and shaking generated by the yarn feeding device can easily cause relative sliding between the inclined surface of the triangular block and the inclined surface of the extrusion block, thereby affecting the tensioning and limiting effect on the yarn bobbin and reducing the stability of the yarn bobbin. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, the purpose of this utility model is to propose a yarn feeding device for yarn processing. By adopting a tensioning installation and combining it with an axial limiting design, the device effectively limits the yarn bobbin, improves the problem of poor yarn bobbin stability during the yarn feeding process, and enhances the stability and reliability of yarn conveying.

[0007] To achieve the above objectives, this utility model proposes a yarn feeding device for yarn processing, comprising a mounting frame, multiple mounting shafts, a yarn bobbin limiting device, and a yarn tensioning assembly. The multiple mounting shafts are equidistantly arranged on the mounting frame. The yarn bobbin limiting device is mounted on the mounting shaft and rotatably connected to the mounting frame via the mounting shaft. The yarn tensioning assembly is mounted on the mounting frame and corresponds to the position of the yarn bobbin limiting device. The yarn bobbin limiting device includes a tensioning limiting assembly, a positioning ring, and an anti-detachment assembly. The anti-detachment assembly and the positioning ring are symmetrically arranged on the tensioning limiting assembly along the axial direction of the mounting shaft. Both the positioning ring and the tensioning limiting assembly are coaxially arranged with the mounting shaft.

[0008] In addition, the yarn feeding device for yarn processing proposed above according to this utility model may also have the following additional technical features: Specifically, the tensioning and limiting assembly includes a guide post, two mounting discs, multiple tensioning blocks, a connecting shaft, and a slider. The two mounting discs are symmetrically arranged at both ends of the connecting shaft, and multiple sliding grooves are symmetrically opened on the opposite faces of the two mounting discs. The multiple tensioning blocks are distributed in a ring along the connecting shaft and are slidably disposed in the sliding grooves by the slider. The guide post is disposed in the sliding groove and is covered with a first elastic element.

[0009] Specifically, the anti-detachment component includes two sliding columns, a pull block, a guide sleeve, and a second elastic element. Two limiting blocks are symmetrically arranged at the far ends of the two sliding columns, and the adjacent ends of the two sliding columns are slidably disposed in the guide sleeve. The second elastic element is located in the guide sleeve and abuts against the two sliding columns respectively. The pull block is disposed on the sliding column.

[0010] Specifically, the yarn tensioning assembly includes a mounting plate, a guide rod, a sliding seat, a connecting rod, and a tensioning rod. One end of the tensioning rod is pivotally connected to the mounting plate, and the other end of the tensioning rod is provided with a tensioning wheel. One end of the connecting rod is pivotally connected to the tensioning rod, and the other end of the connecting rod is pivotally connected to the sliding seat. The mounting plate is provided with a guide rail, the sliding seat is slidably disposed within the guide rail, the guide rod is disposed within the guide rail, and a third elastic element is sleeved on its exterior. The sliding seat is slidably disposed on the guide rod and is connected to the third elastic element.

[0011] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: This invention, by setting a tensioning limiting component, ensures that the tensioning block remains in close contact with the yarn bobbin under the action of the first elastic element, thereby limiting the position of the yarn bobbin. This allows the yarn bobbin to remain stable during rotational yarn feeding, reducing problems such as yarn breakage or uneven yarn feeding caused by yarn bobbin swaying. At the same time, in conjunction with the anti-detachment component, the axial position of the yarn bobbin is limited, further enhancing the stability of the yarn bobbin and preventing it from falling off during high-speed rotation or due to equipment vibration or swaying, thus ensuring the continuity and stability of the production process.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0015] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The yarn feeding device for yarn processing according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0017] like Figures 1-6 As shown in the figure, a yarn feeding device for yarn processing according to an embodiment of the present invention includes a mounting frame 1, multiple mounting shafts 2, a yarn bobbin limiting device, and a yarn tensioning assembly 6. The multiple mounting shafts 2 are equidistantly arranged on the mounting frame 1. The yarn bobbin limiting device is arranged on the mounting shaft 2 and is rotatably connected to the mounting frame 1 through the mounting shaft 2. The yarn tensioning assembly 6 is arranged on the mounting frame 1 and corresponds to the position of the yarn bobbin limiting device.

[0018] It should be noted that the mounting shaft 2 is used to install the yarn bobbin limiting device. Each yarn bobbin limiting device corresponds to a yarn tensioning component 6. The mounting shaft 2 is rotatably connected to a rotating shaft through a bearing. The end of the rotating shaft is connected to the yarn bobbin limiting device, so that the yarn bobbin limiting device can rotate with the rotating shaft, thereby realizing the rotational yarn feeding operation of the yarn bobbin.

[0019] The yarn bobbin limiting device is used to limit the yarn bobbin to prevent it from falling off or shifting during the yarn feeding process. The yarn tensioning component 6 is used to tension the yarn to ensure that the yarn can be fed with constant tension.

[0020] The yarn bobbin limiting device includes a tension limiting component 3, a positioning ring 4, and an anti-detachment component 5. The anti-detachment component 5 and the positioning ring 4 are symmetrically arranged on the tension limiting component 3 along the axial direction of the mounting shaft 2. Both the positioning ring 4 and the tension limiting component 3 are coaxially arranged with the mounting shaft 2.

[0021] It should be noted that the tensioning limit component 3 is used to tension and limit the yarn bobbin to ensure that the yarn bobbin remains stable during the yarn feeding process.

[0022] The positioning ring 4 is used to position the yarn bobbin, thereby ensuring that the yarn bobbin can be installed in place.

[0023] The anti-loosening component 5 is used to prevent the yarn bobbin from axially displacing on the tensioning limit component 3, thereby preventing it from falling off and ensuring the continuity and stability of the yarn feeding process.

[0024] Understandably, during the installation of the yarn bobbin, the yarn bobbin is fitted onto the outside of the tensioning and limiting assembly 3, so that the yarn bobbin contacts the positioning ring 4. At this time, the tensioning and limiting assembly 3 tensions and fixes the yarn bobbin, and the anti-detachment assembly 5 axially limits the yarn bobbin. Then, the yarn on the yarn bobbin is pulled through the yarn tensioning assembly 6 and connected to the textile equipment. During the yarn feeding operation, the yarn tensioning assembly 6 can ensure that the yarn maintains a constant tension during the conveying process.

[0025] In one embodiment of this utility model, such as Figures 2-4 As shown, the tensioning and limiting assembly 3 includes a guide post 33, two mounting discs 34, multiple tensioning blocks 35, a connecting shaft 36, and a slider 37. The two mounting discs 34 are symmetrically arranged at both ends of the connecting shaft 36, and multiple sliding grooves 32 are symmetrically opened on the opposite surfaces of the two mounting discs 34. The multiple tensioning blocks 35 are distributed in a ring along the connecting shaft 36 and are slidably disposed in the sliding grooves 32 by the slider 37. The guide post 33 is disposed in the sliding groove 32, and a first elastic element 31 is sleeved on its outside.

[0026] It should be noted that the two mounting discs 34 are fixed at both ends of the connecting shaft 36, and one mounting disc 34 is connected to the mounting shaft 2, so that the tensioning limit assembly 3 can rotate with the mounting shaft 2.

[0027] The shape of the groove 32 is adapted to the shape of the slider 37, and the slider 37 can slide along the groove 32. A limiting hole is provided on the slider 37, and the position of the limiting hole corresponds to the position of the guide post 33. The first elastic element 31 is a spring, which is sleeved on the outside of the guide post 33. Its bottom end is at the bottom of the groove 32, and its top end is located in the limiting hole and abuts against the slider 37, thereby providing radial outward elastic force to the slider 37 and the tensioning block 35 connected thereto.

[0028] Understandably, the tensioning block 35, pushed by the first elastic element 31, bears a force away from the connecting shaft 36. When installing the yarn bobbin, when the tensioning block 35 is subjected to the inward squeezing force of the yarn bobbin, the tensioning block 35 will slide inward along the slide groove 32 through the slider 37, while compressing the first elastic element 31. The first elastic element 31 generates a reverse elastic force, which acts on the tensioning block 35 through the slider 37, so that the tensioning block 35 generates a reverse tensioning force on the yarn bobbin, thereby achieving tensioning and limiting of the yarn bobbin.

[0029] In one embodiment of this utility model, such as Figure 5As shown, the anti-detachment component 5 includes two sliding posts 52, a pull block 53, a guide sleeve 54, and a second elastic element 55. Two limiting blocks 51 are symmetrically arranged at the far ends of the two sliding posts 52, and the adjacent ends of the two sliding posts 52 are slidably disposed in the guide sleeve 54. The second elastic element 55 is located in the guide sleeve 54 and abuts against the two sliding posts 52 respectively. The pull block 53 is disposed on the sliding post 52.

[0030] It should be noted that the guide sleeve 54 is fixedly installed on a mounting plate 34 away from the mounting shaft 2, thereby defining the position of the anti-detachment component 5.

[0031] The second elastic element 55 is a spring. A through groove adapted to the pull block 53 is provided on the outer wall of the guide sleeve 54. The pull block 53 can be limited by the through groove to prevent the sliding column 52 from coming out of the guide sleeve 54. The side of the limiting block 51 away from the mounting plate 34 is an inclined surface.

[0032] Understandably, during yarn bobbin installation, the yarn bobbin contacts the inclined surfaces on the two limiting blocks 51, and simultaneously pushes the limiting blocks 51 through the inclined surfaces. The limiting blocks 51 drive the sliding columns 52, and the two sliding columns 52 approach each other within the guide sleeve 54. When the yarn bobbin is installed in place, the limiting blocks 51 pass over the end face of the yarn bobbin. Under the elastic force of the second elastic element 55, the two limiting blocks 51 reset outward, thereby limiting the yarn bobbin axially and preventing it from displacing and falling off along the axis of the mounting shaft 2 during yarn feeding.

[0033] In addition, when it is necessary to disassemble the yarn bobbin, pull the two pull blocks 53. The pull blocks 53 drive the limiting blocks 51 through the sliding column 52. The two limiting blocks 51 move closer to each other. At this time, the axial limitation on the yarn bobbin is released, and the yarn bobbin can be removed.

[0034] In one embodiment of this utility model, such as Figure 6 As shown, the yarn tensioning assembly 6 includes a mounting plate 61, a guide rod 62, a sliding seat 63, a connecting rod 65, and a tensioning rod 66. One end of the tensioning rod 66 is pivotally connected to the mounting plate 61, and the other end of the tensioning rod 66 is provided with a tensioning wheel 67. One end of the connecting rod 65 is pivotally connected to the tensioning rod 66, and the other end of the connecting rod 65 is pivotally connected to the sliding seat 63. A guide rail 68 is provided on the mounting plate 61, and the sliding seat 63 is slidably disposed within the guide rail 68. The guide rod 62 is disposed within the guide rail 68, and a third elastic element 64 is sleeved on its exterior. The sliding seat 63 is slidably disposed on the guide rod 62 and is connected to the third elastic element 64.

[0035] It should be noted that the mounting plate 61 is fixedly mounted on the mounting bracket 1, the guide rail 68 is opened in the vertical direction, and the sliding seat 63 can slide in the guide rail 68 along the length of the guide rod 62; the guide rod 62 plays a guiding and limiting role in the sliding of the sliding seat 63, ensuring that the sliding seat 63 can slide smoothly.

[0036] The third elastic element 64 is a spring, which is sleeved on the outside of the guide rod 62, with one end abutting against the inner wall of the guide rail 68 and the other end abutting against the sliding seat 63. The spring force can push the sliding seat 63 to slide. The two ends of the connecting rod 65 are pivotally connected to the tensioning rod 66 and the sliding seat 63 respectively. When the sliding seat 63 slides, the connecting rod 65 can drive the tensioning rod 66 to rotate. The tensioning rod 66 drives the tensioning wheel 67 to swing. The tensioning wheel 67 is used to contact the yarn and tension the yarn.

[0037] Understandably, when the yarn tension changes during transport, the yarn pushes the tensioning wheel 67. The tensioning wheel 67 drives the sliding seat 63 to slide through the tensioning rod 66 and the connecting rod 65. The sliding seat 63 compresses the third elastic element 64, which generates a reverse elastic force. This elastic force acts on the tensioning wheel 67 through the sliding seat 63, the connecting rod 65, and the tensioning rod 66, causing the tensioning wheel 67 to generate a reverse tension force on the yarn. This achieves automatic adjustment of the yarn tension, ensuring that the yarn maintains a constant tension during transport.

[0038] In summary, the yarn feeding device for yarn processing according to this utility model, when installing the yarn bobbin, uses a positioning ring to position the yarn bobbin, ensuring its proper installation. The tensioning and limiting component tensions and fixes the yarn bobbin, ensuring its stability during the yarn feeding process. The anti-detachment component axially limits the yarn bobbin, preventing it from falling off. Simultaneously, the yarn tensioning component automatically adjusts the yarn tension, ensuring the yarn maintains constant tension throughout the feeding process, thus improving the quality and efficiency of yarn processing. Compared to existing technologies, this utility model, through the design of the tensioning and limiting component, ensures the yarn bobbin remains stable during rotational yarn feeding, reducing problems such as yarn breakage or uneven yarn feeding caused by yarn bobbin swaying. Furthermore, the anti-detachment component further enhances the stability of the yarn bobbin, preventing it from falling off during high-speed rotation or due to equipment vibration or swaying, ensuring the continuity and stability of the production process.
