Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a high-efficiency circular knitting machine for underwear. Background Technology

[0002] A high-efficiency circular knitting machine is a machine used to produce textiles, including various fabrics such as underwear. This type of machine is typically used to produce continuous circular or tubular fabrics, such as socks, pantyhose, and T-shirts. High-efficiency circular knitting machines for underwear may be structurally similar to ordinary circular knitting machines; they may share some basic mechanical structures and components, such as the needle bed, needle holder, and drive system. These basic structures and components are common in the design and manufacture of circular knitting machines. The yarn carriage is an important component of the circular knitting machine, used to guide and transport the yarn bundles, facilitating the knitting of the underwear by the needle carriage.

[0003] The tension of the yarn wheels on a common yarn frame is adjusted manually by operating the lower yarn wheels. Usually, the operator needs to adjust each one individually to ensure that the tension of each yarn wheel meets the required standard. However, this method, because it is adjusted one by one, is prone to errors in the adjustment height of the yarn wheels, which will affect the subsequent production of underwear. In view of this, we propose a high-efficiency circular knitting machine for underwear. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a high-efficiency circular knitting machine for underwear.

[0005] The technical solution of this utility model is as follows: A high-efficiency circular knitting machine for underwear includes a yarn frame. A first support is installed on the outer surface wall of the top ring of the yarn frame. A first bearing seat is installed on the bottom wall of a plurality of first supports. The rotating ends of the plurality of first bearing seats are respectively connected to a first threaded rod. A yarn bobbin is sleeved on the outer ring surface of the first threaded rod. A second support is installed on the inner ring surface of the top ring of the yarn frame. A first guide frame and an adjustment component are arranged on the plurality of second supports to facilitate the conveying of the yarn bundle. A transmission belt is sleeved on the rotating structure of the plurality of adjustment components. A base is connected to the inner surface wall of the bottom ring of the yarn frame. A forward and reverse motor is installed on the top wall of the base to provide power for adjusting the tension of the yarn bundle.

[0006] Preferably, the first bracket is in the shape of an inverted L, and the first bearing seat is mounted on the bottom wall of the horizontal structure of the first bracket.

[0007] Preferably, the yarn bobbin has a first threaded hole, and the first threaded rod is disposed in the first threaded hole at the corresponding position.

[0008] Preferably, the adjustment component includes a positioning block, a second bearing seat is installed on the bottom wall of the positioning block, a second threaded rod is connected to the rotating end of the second bearing seat, and the bottom end of the second threaded rod is connected to the output end of the forward and reverse motor.

[0009] Preferably, a movable block and a gear are fitted on the outer ring surface of the second threaded rod, and a second guide frame is connected to one side wall of the movable block.

[0010] Preferably, the movable block has a second threaded hole, and the second threaded rod is disposed in the second threaded hole.

[0011] Preferably, the vertical structure of the second bracket has a guide groove, and the movable block is disposed in the guide groove.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] This invention facilitates the transmission of the wire harness through the cooperation of the first wire guide frame and the adjustment components. By activating the forward and reverse motors, the gears in one set of adjustment components rotate. Under the transmission belt, the rotating gears in multiple adjustment components also rotate. These rotating gears, in conjunction with the second bearing seat, drive the second threaded rod to rotate. This rotation of the movable block and the second wire guide frame allows for the adjustment of the wire harness tension, preventing loose wire harnesses from tangling during transmission and preventing the wire harness from becoming too tight and prone to breakage. Furthermore, the simultaneous adjustment of multiple wire harnesses reduces the risk of errors from individual adjustments, providing convenience for subsequent underwear knitting processing.

Detailed Implementation

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example

[0020] like Figure 1-3 As shown, this utility model proposes a high-efficiency circular knitting machine for underwear, comprising a yarn frame 1, multiple first supports 2 all in an inverted L-shape and distributed in a ring on the outer surface of the top ring of the yarn frame 1, the vertical sidewalls of the multiple first supports 2 all connected to the outer surface of the top ring of the yarn frame 1; multiple first bearing seats 3 are fixedly installed on the bottom wall of the horizontal structure of the multiple first supports 2, supporting the first bearing seats 3 through the first supports 2; the top ends of multiple first threaded rods 4 are respectively connected to the rotating ends of the multiple first bearing seats 3, facilitating the rotation of the first threaded rods 4 with the assistance of the first bearing seats 3, avoiding interference with subsequent yarn harness processing. The yarn spools 5 are guided and conveyed by multiple yarn bobbins 5, which are connected to multiple first threaded rods 4 through first threaded holes. The first threaded holes make it easy for workers to unscrew the yarn bobbins 5 from the first threaded rods 4, which is convenient for replacement and avoids affecting the weaving process of underwear after the yarn bundle is used up. The multiple second supports 6 are also inverted L-shapes. The transverse structural sidewalls of the multiple second supports 6 are fixedly connected to the inner ring surface of the top ring of the yarn frame 1, and are also distributed in a ring array so that their positions correspond to the positions of the first supports 2, avoiding the deviation between the positions of the first supports 2 and the second supports 6, which would affect the conduction and conveying of the yarn bundle on the yarn bobbins 5.

[0021] Furthermore, each of the multiple second supports 6 is equipped with a first conductor frame 7 and an adjustment assembly 8 for facilitating the transport of the wire harness. The adjustment assembly 8 includes a positioning block 81, the side wall of which is fixedly connected to the vertical structure of the second support 6, and the second support 6 supports the positioning block 81. A second bearing seat 82 is fixedly installed on the bottom wall of the positioning block 81, and the top end of the second threaded rod 86 is connected to the rotating end of the second bearing seat 82, which facilitates the rotation of the second threaded rod 86 by means of the second bearing seat 82. A second threaded hole is provided on the movable block 83, and the second bearing seat 82 is sleeved on the outer ring surface of the second threaded rod 86 through the second threaded hole, which facilitates the rotation of the second threaded rod 86 by means of the second threaded hole. The rotation of the threaded rod 86 drives the movable block 83 to move. The movable block 83 is also set in a guide groove opened on the vertical structure of the second bracket 6 to prevent the movable block 83 from rotating with the second threaded rod 86 and thus avoid affecting the height adjustment of the movable block 83. The gear 84 is fixedly sleeved on the outer ring surface of the second threaded rod 86, so that the rotation of the second threaded rod 86 can drive the gear 84 to rotate. The transmission belt 9 is sleeved on the outer ring of the gear 84 in the multiple sets of adjustment components 8 and meshes with the teeth of the gear 84. This arrangement of the gear 84 allows one gear 84 to drive the rotation of the other sets of gears 84 with the assistance of the transmission belt 9, so that the movable block 83 can move in multiple directions. With gear 84 in place, synchronous lifting and lowering are achieved. The second wire guide frame 85 is installed on the side wall of the movable block 83. The second wire guide frame 85 is also located on one side wall of the vertical structure of the second support 6, which facilitates vertical lifting and lowering of the second wire guide frame 85 under the guidance of the movable block 83. This allows the second wire guide frame 85 to approach or move away from the first wire guide frame 7, enabling simultaneous tension adjustment of multiple wire harnesses without the need for manual adjustment, reducing the risk of errors and avoiding impact on subsequent wire harness delivery. The forward and reverse motor 11 is installed on the top wall of the base 10. The output end of the forward and reverse motor 11 is connected to the bottom end of the second threaded rod 86, facilitating the driving of the second threaded rod. The rotation of the thread rod 86 provides power for adjusting the tension of the yarn harness. By adjusting the tension of the yarn harness, it is possible to prevent the yarn harness from becoming loose and tangled during transmission, and to prevent the yarn harness from becoming too tight and breaking during transmission, thus affecting the progress of the underwear knitting process. The first guide frame 7 and the second guide frame 85 are structurally similar, both consisting of an auxiliary frame and a yarn wheel. The yarn wheel of the second guide frame 85 is staggered from the yarn wheel of the first guide frame 7, which facilitates the rotation of the yarn wheel during transmission and prevents the temperature of the yarn harness from rising due to friction, thereby reducing the risk of breakage and yarn slugging. The base 10 is installed on the inner ring surface of the bottom ring of the yarn frame 1 to support the forward and reverse motors 11.

[0022] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
