Abstract
Description
Technical Field
[0001] The embodiments of this utility model relate to the field of towel loop weaving technology, specifically, to an anti-snagging towel loop weaving device. Background Technology
[0002] Towels are typically made of three types of yarns: pile warp, ground warp, and weft, resulting in a terry or looped surface. They are mainly used for everyday purposes such as washing, warmth, and decoration. Towels are classified as single-sided or double-sided based on the loop distribution. The ground warp and weft interweave to form the base fabric, while the pile warp and weft interweave to form the looped surface.
[0003] In existing technologies, it is difficult to adjust the tension of yarn during weaving in a knitting machine, resulting in uneven yarn tension. This leads to a loose and messy terry loop fabric. Therefore, we propose an anti-snagging terry loop weaving device. Utility Model Content
[0004] To overcome the above-mentioned defects, embodiments of this utility model provide an anti-snagging towel loop weaving device, which solves the problem of not being able to adjust yarn tension in related technologies.
[0005] According to one aspect, at least one embodiment of the present invention provides an anti-snagging towel loop knitting device, including a knitting machine, a control panel provided on the side of the knitting machine, a knitting component provided inside the knitting machine, a stretching mechanism provided inside the knitting machine, and a take-up roller provided on the side of the knitting machine. The knitting component adopts double-strand single-pitch knitting, which improves the towel resistance and prevents the towel from snagging.
[0006] The stretching mechanism includes a power chamber and a motor. The power chamber is located inside the knitting machine and is fixedly connected to the side of the motor. A threaded rod is fixedly connected to the output end of the motor. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod. A connecting rod is fixedly connected to the side of the threaded sleeve. The side of the connecting rod penetrates and slides through the inner wall of the power chamber. An adjusting plate is fixedly connected to the end of the connecting rod away from the side of the threaded sleeve. A conveying port is opened on the side of the adjusting plate. The purpose of this is to ensure uniform yarn tension, making the terry fabric tighter and neater.
[0007] For example, in at least one embodiment of the present invention, an anti-snagging towel loop knitting device is provided, which further includes: a sliding groove is provided inside the adjusting plate, a support shaft is slidably connected inside the sliding groove, and a pressing shaft is rotatably connected to the circumferential surface of the support shaft, the purpose of which is to ensure stable yarn feeding.
[0008] A compression spring is fixedly connected inside the adjusting plate. The end of the compression spring away from the inner wall of the adjusting plate is fixedly connected to the circumferential surface of the support shaft. Its purpose is to press and restrict the yarn to prevent the yarn from intertwining.
[0009] A limiting plate is fixedly connected to the inner wall of the power compartment. The bottom of the limiting plate penetrates the circumferential surface of the threaded rod. A conveying shaft is rotatably connected to the top of the braiding machine. The function of the limiting plate is to limit the displacement distance of the threaded sleeve, and the function of the conveying shaft is to improve the conveying effect of the yarn.
[0010] The number of the slide, pressing shaft and compression spring is set to two, and they are symmetrical to each other along the vertical central axis of the adjusting plate. The initial state of the compression spring is relaxed, which is to ensure that the yarn can be transported stably.
[0011] According to another aspect, at least one embodiment of this utility model also provides an anti-snagging towel loop weaving device, including a finishing mechanism. The finishing mechanism includes a rotating shaft, one end of which is fixedly connected to one end of a threaded rod. A gear is fixedly passed through the circumference of the rotating shaft. A moving groove is provided on the inner wall of the power chamber. A rack is slidably connected inside the moving groove. A push rod is fixedly connected to the side of the rack. A hydraulic cylinder is fixedly connected inside the power chamber. One end of the hydraulic cylinder is slidably connected to a force-bearing rod through a piston. The force-bearing rod is driven by a hydraulic rod through the hydraulic cylinder. A finishing sleeve is fixedly connected to the end of the hydraulic rod away from the side of the hydraulic cylinder. The purpose of this is to prevent unevenness on both sides of the rolled-up towel when adjusting the tension.
[0012] For example, in at least one embodiment of the present invention, an anti-snagging towel loop weaving device is provided, which further includes: a return spring fixedly connected to the side of the hydraulic cylinder, and the end of the return spring away from the side of the hydraulic cylinder is fixedly connected to the circumferential surface of the force-bearing rod. The purpose is to ensure that the force-bearing rod can automatically reset and reduce manual intervention.
[0013] The hydraulic cylinder has a sliding groove on its side, and a pressing plate is slidably connected inside the sliding groove. A movable column is fixedly connected to the side of the pressing plate. The purpose of this is to press the surface of the rolled-up towel to prevent the edges from curling up.
[0014] A tension spring is fixedly connected to the side of the hydraulic cylinder. The end of the tension spring away from the side of the hydraulic cylinder is fixedly connected to the side of the pressing plate. The purpose of this is to ensure that the pressing plate can automatically reset and reduce manual intervention.
[0015] The circumferential surface of the gear is fixedly connected to the side of the rack. One end of the force-bearing rod and the moving column are both located on the displacement trajectory of the push rod. The purpose is to ensure that the rotation of the gear can drive the rack to move, and the movement of the push rod can simultaneously squeeze the force-bearing rod and the moving column.
[0016] The beneficial effects of the embodiments of this utility model are as follows:
[0017] 1. In this utility model, through the cooperation of components such as the motor, adjusting plate, and conveying shaft of the stretching mechanism, when it is necessary to weave towel loops, after the worker installs the yarn, the worker can observe the yarn tension by starting the motor, causing the adjusting plate to move upward. At this time, the yarn, through the elasticity of the compression spring, drives the support shaft to move inside the slide groove. The support shaft drives the pressing shaft to press and restrict the yarn. Therefore, when the adjusting plate moves to adjust the yarn tension, the yarn will not cross due to the movement, thus adjusting the yarn to a suitable tension. This design achieves the effect of adjusting the yarn tension, ensuring uniform yarn tension, and making the loop fabric more compact and neat.
[0018] 2. In this utility model, through the mutual cooperation between the gears, racks, and sorting sleeves of the sorting mechanism, when the threaded rod rotates, it drives the rotating shaft to rotate. The rotating shaft drives the gear to rotate. Through the meshing between the gear and the rack, the push rod is pressed against the force rod during its movement. The sorting sleeve moves to sort both sides of the towel during the winding process. At the same time, the push rod presses against the moving column. The moving column moves through the sliding groove under force, causing the pressing plate to move. The moving pressing plate presses the towel during the winding process. This design achieves the effect of sorting the wound towel and prevents unevenness and curling edges from occurring when the towel is wound after weaving. Attached Figure Description

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0033] like Figures 1-6 As shown, it illustrates an anti-snagging towel loop knitting device according to an embodiment of the present invention, including a knitting machine 1, a control panel 2 on the side of the knitting machine 1, a knitting component 3 inside the knitting machine 1, a stretching mechanism 4 inside the knitting machine 1, and a take-up roller 5 on the side of the knitting machine 1. The knitting component 3 adopts double-strand single-pitch knitting, which improves the towel resistance and prevents the towel from snagging.
[0034] The stretching mechanism 4 includes a power chamber 41 and a motor 42. The power chamber 41 is located inside the knitting machine 1. The interior of the power chamber 41 is fixedly connected to the side of the motor 42. A threaded rod 43 is fixedly connected to the output end of the motor 42. A threaded sleeve 44 is threadedly connected to the circumferential surface of the threaded rod 43. A connecting rod 45 is fixedly connected to the side of the threaded sleeve 44. The side of the connecting rod 45 penetrates and slides through the inner wall of the power chamber 41. An adjusting plate 46 is fixedly connected to the end of the connecting rod 45 away from the side of the threaded sleeve 44. A conveying port 47 is provided on the side of the adjusting plate 46. The purpose of this is to ensure uniform yarn tension, so that the terry cloth fabric is tighter and neater.
[0035] In some examples, the adjustment plate 46 is provided with a groove 413 inside, a support shaft 48 is slidably connected inside the groove 413, and a pressing shaft 49 is rotatably connected to the circumferential surface of the support shaft 48, the purpose of which is to ensure stable yarn delivery.
[0036] A compression spring 410 is fixedly connected inside the adjusting plate 46. The end of the compression spring 410 away from the inner wall of the adjusting plate 46 is fixedly connected to the circumferential surface of the support shaft 48. Its purpose is to press and restrict the yarn to prevent the yarn from interlacing.
[0037] A limiting plate 411 is fixedly connected to the inner wall of the power compartment 41. The bottom of the limiting plate 411 penetrates the circumferential surface of the threaded rod 43. A conveying shaft 412 is rotatably connected to the top of the braiding machine 1. The function of the limiting plate 411 is to limit the displacement distance of the threaded sleeve 44, and the function of the conveying shaft 412 is to improve the conveying effect of the yarn.
[0038] The number of slide groove 413, pressing shaft 49 and compression spring 410 is set to two, and they are symmetrical to each other along the vertical central axis of adjusting plate 46. The initial state of compression spring 410 is relaxed, which is to ensure that the yarn can be transported stably.
[0039] For example, such as Figures 1-6 As shown, when it is necessary to weave the terry loops of a towel, after the worker installs the yarn, the worker can observe the yarn tension by using the weaving component 3 to weave the towel. The worker can start the motor 42, and the output end of the motor 42 will rotate. The rotation of the output end of the motor 42 will drive the threaded rod 43 to rotate, and the rotation of the threaded rod 43 will drive the threaded sleeve 44 to move. The movement of the threaded sleeve 44 will drive the adjusting plate 46 to move upward through the connecting rod 45. At this time, the yarn will move the support shaft 48 inside the slide groove 413 through the elasticity of the compression spring 410. The support shaft 48 will drive the pressing shaft 49 to press and restrict the yarn. Therefore, when the adjusting plate 46 moves to adjust the yarn tension, the yarn will not cross due to the movement, and the yarn will be adjusted to a suitable tension, making the terry loop fabric tighter and neater. At this time, the towel is woven using the double-strand single-distance weaving method through the weaving component 3. The woven towel is then wound up by the take-up roller 5.
[0040] like Figures 1-6 As shown, this invention illustrates another embodiment of an anti-snagging towel loop weaving device, which is largely the same as the above-described technical solution. Therefore, only the differences are described. The device includes a sorting mechanism 6, which includes a rotating shaft 61. One end of the rotating shaft 61 is fixedly connected to one end of a threaded rod 43. A gear 62 is fixedly passed through the circumference of the rotating shaft 61. A moving groove 63 is provided on the inner wall of the power chamber 41. A rack 64 is slidably connected inside the moving groove 63. A push rod 65 is fixedly connected to the side of the rack 64. A hydraulic cylinder 66 is fixedly connected inside the power chamber 41. One end of the hydraulic cylinder 66 is slidably connected to a force-bearing rod 67 via a piston. The force-bearing rod 67 is driven by a hydraulic rod 68 via the hydraulic cylinder 66. A sorting sleeve 69 is fixedly connected to the end of the hydraulic rod 68 away from the side of the hydraulic cylinder 66. The purpose of this is to prevent unevenness on both sides of the rolled-up towel when adjusting the tension.
[0041] In some examples, a return spring 610 is fixedly connected to the side of the hydraulic cylinder 66. The end of the return spring 610 away from the side of the hydraulic cylinder 66 is fixedly connected to the circumferential surface of the force rod 67. The purpose is to ensure that the force rod 67 can automatically reset and reduce manual intervention.
[0042] The hydraulic cylinder 66 has a sliding groove 611 on its side. A pressing plate 612 is slidably connected inside the sliding groove 611. A moving column 613 is fixedly connected to the side of the pressing plate 612. The purpose of this is to press the surface of the rolled-up towel to prevent the edges from curling up.
[0043] A tension spring 614 is fixedly connected to the side of the hydraulic cylinder 66. The end of the tension spring 614 away from the side of the hydraulic cylinder 66 is fixedly connected to the side of the pressing plate 612. The purpose is to ensure that the pressing plate 612 can automatically reset and reduce manual intervention.
[0044] The circumferential surface of gear 62 is fixedly connected to the side of rack 64. One end of force rod 67 and moving column 613 are both located on the displacement trajectory of push rod 65. The purpose is to ensure that the rotation of gear 62 can drive rack 64 to move, and the movement of push rod 65 can simultaneously squeeze force rod 67 and moving column 613.
[0045] For example, such as Figures 1-6 As shown, when the threaded rod 43 rotates, it drives the rotating shaft 61 to rotate. The rotation of the rotating shaft 61 drives the gear 62 to rotate. Through the meshing between the gear 62 and the rack 64, the rotation of the gear 62 drives the rack 64 to move inside the moving groove 63. The movement of the rack 64 drives the push rod 65 to move. During the movement of the push rod 65, it squeezes the force rod 67. The force rod 67 is forced to retract into the hydraulic cylinder 66. At this time, the hydraulic rod 68 is forced outward by the pressure of the liquid inside the hydraulic cylinder 66. The extension of the hydraulic rod 68 drives the sorting sleeve 69 to move, sorting the two sides of the towel during winding to prevent unevenness during towel winding. At the same time, the push rod 65 squeezes the moving column 613. The moving column 613 is forced to move through the sliding groove 611, causing the pressing plate 612 to move. The moving pressing plate 612 presses the towel during winding to prevent the surface of the wound towel from curling up.
[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
