Description

Technical Field

[0001] This application relates to the field of textile machinery, and in particular to a yarn isolation mechanism for a warp knitting machine. Background Technology

[0002] A warp knitting machine uses one or more groups of parallel yarns fed into all the working needles of the machine in the warp direction to simultaneously form loops and create knitted fabric. It is a commonly used piece of machinery in the textile machinery field. A warp knitting machine mainly consists of a knitting mechanism, a guide bar traverse mechanism, a warp feed mechanism, a take-up and tension mechanism, and a transmission mechanism. Warp knitting machines are highly adaptable to various raw materials and fabric types, and have high productivity, thus leading to their rapid development.

[0003] When a warp knitting machine feeds yarn, several yarns are fed at the same time, resulting in dense yarns with small intervals between them. This can easily cause the yarns to shift, leading to mistakes or tangling during knitting. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a warp knitting machine yarn isolation mechanism.

[0005] The technical solution for a warp knitting machine yarn isolation mechanism provided in this application is as follows:

[0006] A warp knitting machine yarn isolation mechanism includes a yarn frame, a mounting frame, yarn bobbins, inserts, and a separating component. The yarn frame provides overall load-bearing capacity. Several mounting frames are installed at predetermined intervals along the vertical direction of the yarn frame. Several inserts are installed on the mounting frames and extend horizontally. Each insert is fitted with a yarn bobbin, and yarn is wound on the surface of the yarn bobbin. The separating component is installed on the yarn frame and is arranged along the horizontal extension direction of the yarn frame. The yarn passes through the separating component and is separated and conveyed to external knitting equipment.

[0007] By adopting the above technical solution, the yarn frame and mounting frame provide installation and load-bearing functions. Several yarn bobbins are sleeved on the corresponding inserts. When unwinding, the yarn is pulled out by rotating along the inserts. The yarn is separated by the separating components to ensure the stability of the yarn conveying.

[0008] Optionally, the separating component includes a separating part, a pulling part, and an adjusting part; the pulling part is provided in two sets, which are respectively connected to the yarn frames at both ends and extend through the yarn frames in a direction away from the mounting frame; the adjusting part is screwed to the pulling part and provides a limit for the pulling part; the separating part is elastic, and its two ends are respectively connected to the two sets of the pulling parts, and the pulling part is divided with a plurality of separating openings for yarn to pass through.

[0009] By adopting the above technical solution, the separation part is opened by fixing the pulling part, and the position of the pulling part is adjusted by the adjusting part to adjust the degree of opening of the separation part, thereby adjusting the position of the yarn passing through the separation part, and providing a certain tension effect by utilizing the elastic effect.

[0010] Optionally, the pulling part includes a pulling hook and a screw; the pulling hook is installed at one end of the screw; the screw passes through the yarn frame, and the adjusting part is screwed to the screw.

[0011] By adopting the above technical solution, the position of the adjusting screw is adjusted through the adjusting part, thereby achieving the function of adjusting the position of the pulling hook.

[0012] Optionally, each end of the partition is provided with a hanging ring.

[0013] By adopting the above technical solution, when maintenance or repair is required, the device can be directly removed from the surface of the pull hook via the hanging ring, improving ease of use.

[0014] Optionally, at least one set of the pull hooks may be provided.

[0015] By adopting the above technical solution, the purpose of setting multiple sets of pull hooks is to make it easier and more convenient to adjust the tightness of the partition and the size of the partition opening. Simply remove the hanging ring from one pull hook and hook it onto another pull hook that is farther or closer to adjust the tightness of the partition and the size of the unfolded partition opening. At the same time, it can also be used in conjunction with the adjustment part for further adjustment, improving the convenience and flexibility of adjustment.

[0016] Optionally, the separating component further includes a lifting section; the lifting section is provided in a plurality of such sections and is installed on the mounting frame at preset intervals, and the separating section is located on the lifting section.

[0017] By adopting the above technical solution, the lifting part is used to hold the lower part of the partition, so that the partition will not sag under force, thus improving the partition stability of the partition.

[0018] Optionally, the dividing part is a dividing segment and an adjusting segment. A set of adjusting segments is provided between two adjacent dividing segments. The lifting part has a lifting opening. The adjusting segment is located in the lifting opening. The adjusting segment is provided with a limiting protrusion at a preset distance. The limiting protrusion is engaged with the lifting opening.

[0019] By adopting the above technical solution, the size of the limiting protrusion is larger than the lifting opening, so it will be stuck by the lifting opening. The adjustment section is equipped with multiple limiting protrusions, so that the adjustment section between adjacent limiting protrusions can be inserted into the lifting opening. By adjusting the position of the adjustment section at the lifting opening of different limiting protrusions, the pulling position of the partition can be adjusted.

[0020] Optionally, the number of separator components shall be at least one set, and if there are multiple sets, they shall be spaced apart in the vertical direction.

[0021] By adopting the above technical solution, setting multiple separating components can separate the yarn at certain intervals, allowing the yarn to be transported more orderly and avoiding the situation where the yarn is deviated due to airflow, humidity, etc., because the span is too long.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0038] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0039] This application discloses a yarn isolation mechanism for a warp knitting machine.

[0040] A yarn isolation mechanism for a warp knitting machine is applied to the warp knitting machine to prevent the yarns from tangling together during the yarn feeding process.

[0041] refer to Figure 1 and Figure 2 As shown, it includes a yarn frame 1, a mounting frame 2, a yarn tube 3, an insert 4, and a partition assembly 5; the yarn frame 1 is arranged vertically to provide overall load-bearing capacity, and includes several vertically arranged support frames and a horizontally arranged crossbeam frame, with the support frames installed at the bottom of the crossbeam frame to provide load-bearing capacity for the crossbeam frame.

[0042] The mounting frame 2 is provided in several parts and is divided into two groups, front and back. The front group is installed at a preset distance along the vertical direction of the yarn frame 1, and the back group extends backward at a preset distance. The connection point of the mounting frame 2 is the crossbeam in the yarn frame 1 and extends in the vertical direction. The back group is used for installation through the yarn tube 3.

[0043] Several inserts 4 are provided and installed on the mounting frame 2, specifically in the last set of mounting frames 2. The inserts 4 extend horizontally and provide installation for the yarn tube 3. The inserts 4 can be insert rods, and each insert rod has an anti-drop buckle at the end to prevent the yarn tube 3 from falling off when the yarn is pulled.

[0044] Each insert 4 is fitted with a yarn tube 3, which can rotate along the insert 4. Yarn is wound on the surface of the yarn tube 3. During the rotation of the yarn tube 3, the yarn can be pulled out from the yarn tube 3. The pulled-out yarn is threaded horizontally into the external weaving equipment. The weaving equipment simultaneously provides tension to the yarn to pull out the yarn and perform weaving or spinning work. The yarn can be polyester filament or other textiles.

[0045] Since there are many yarn bobbins 3 on the yarn frame 1, the polyester filaments and other raw materials unwound from each yarn bobbin 3 are easily tangled together during unwinding. Therefore, the yarns can be separated by the separating component 5. The separating component 5 is installed on the yarn frame 1 and is set along the horizontal extension direction of the yarn frame 1 so that the separation range can encompass all the yarns. The yarns are conveyed through the separating component 5.

[0046] Specifically, the yarn frame 1 and the mounting frame 2 provide installation and load-bearing functions. Several yarn bobbins 3 are fitted onto corresponding inserts 4. When unwinding, the yarn is pulled out by rotating along the inserts 4. The yarn is separated by the separating components 5 to ensure the stability of the yarn transport.

[0047] In some embodiments, reference Figure 2 and Figure 3As shown, the separating component 5 includes a separating part 51, a pulling part 52, and an adjusting part 53. The pulling part 52 is provided in two sets, which are respectively connected to the yarn frames 1 at both ends and extend through the yarn frames 1 in a direction away from the mounting frame 2. The yarn frames 1 have through holes for the pulling part 52 to pass through. After the pulling part 52 is inserted into the through hole, it is fixed by the adjusting part 53.

[0048] The adjusting part 53 is screwed to the pulling part 52, which provides a limit for the pulling part 52. The adjusting part 53 can be a nut, and there can be two sets of nuts. One set is located on the side of the thread opening of the yarn frame 1, and the other set is located on the side of the thread opening, thereby limiting the pulling part 52 and preventing the pulling part 52 from moving along the thread opening, so as to achieve the limiting function. After the nut is rotated to adjust the position, the pulling part 52 can move along the thread opening to adjust the position.

[0049] The separator 51 is elastic and serves as the main component for separating yarns. Both ends are connected to two sets of pulling parts 52 respectively, and the connection method is detachable, such as fastening or binding. The separator 51 is divided with several dividing openings 511 for yarns to pass through.

[0050] The separator 51 can be made of tension spring, with its two ends fastened or tied to the two pulling parts 52 respectively. When pulled by the two pulling parts 52, the tension spring unfolds, thereby opening the spiral space and forming the separator 511. The yarn passes through the separator 511. At the same time, by adjusting the position of the pulling parts 52, the tension of the tension spring can be adjusted to adjust the degree of unfolding of the separator 511, adapting to different yarn feeding methods.

[0051] By fixing the pulling part 52, the separating part 51 unfolds the separating opening 511, and the adjusting part 53 adjusts the position of the pulling part 52 to adjust the degree of unfolding of the separating opening 511, thereby adjusting the position of the yarn passing through the separating opening 511, and using the elastic effect to provide a certain tension effect.

[0052] Further reference Figure 3 or Figure 4 As shown, the pulling part 52 includes a pulling hook 522 and a screw 521; the pulling hook 522 is installed at one end of the screw 521; the screw 521 passes through the yarn frame 1, and the adjusting part 53 is screwed to the screw 521. The screw 521 needs to pass through the insertion opening of the yarn frame 1. Therefore, before entering the insertion opening, the adjusting part 53 is screwed in, then passes through the insertion opening, and then falls into another adjusting part 53, so that the screw 521 is fixed by the two adjusting parts 53 and cannot be removed from the insertion opening, thereby completing the installation. The pulling hook 522 provides the fastening or binding of the separating part 51.

[0053] When it is necessary to adjust the position of the pulling part 52, rotate the corresponding adjusting part 53 according to the required adjustment direction to open the adjustable length of the screw 521. Pull the screw 521 along the insertion opening to adjust the position of the pulling hook 522. Finally, rotate the other adjusting part 53 until it reaches the insertion opening of the yarn frame 1 to complete the fixation. The position of the screw 521 is adjusted by adjusting the adjusting part 53 to achieve the function of adjusting the position of the pulling hook 522.

[0054] Furthermore, refer to Figure 3 or Figure 4 As shown, both ends of the divider 51 are provided with hanging rings 512. When the divider 51 uses hanging rings 512, it is easier to connect to the pull hook 522. It can be simply put on the top along the hook opening of the pull hook 522 to fix the position. Then, the position can be adjusted by the screw 521 along with the pull hook 522 to adjust the tightness of the divider 51 or to adjust the unfolding of the divider 51 to open and close the divider opening 511, which is convenient for yarn to be threaded. When maintenance or repair is required, it can also be directly removed from the surface of the pull hook 522 through the hanging rings 512, which improves the convenience of use.

[0055] Further, refer to Figure 4 As shown, at least one set of pull hooks 522 is provided. When one set of pull hooks 522 is provided, the connection of the hanging ring 512 can be completed. When more than one set of pull hooks 522 is provided, several pull hooks 522 can be set at preset intervals along the screw 521. The purpose of setting multiple sets of pull hooks 522 is to make it easier and more convenient to adjust the tightness of the partition 51 and the size of the partition opening 511. Simply remove the hanging ring 512 from one pull hook 522 and hook it into another pull hook 522 that is farther or closer to adjust the tightness of the partition 51 and the size of the unfolded partition opening 511. At the same time, it can also be used in conjunction with the adjustment part 53 for further adjustment, improving the convenience and flexibility of adjustment.

[0056] In some embodiments, since the yarn frame 1 is relatively long, the dividing part 51 extends along the length of the yarn frame 1. The middle part is prone to drooping due to stress, which reduces the dividing effect and affects the accuracy of the yarn threading position. Therefore, the dividing component 5 also includes a lifting part 54.

[0057] The lifting part 54 can be a lifting frame or a lifting seat. Several lifting parts 54 are provided and set at preset intervals. They are installed on the previous set of mounting frames 2. The partition part 51 is located on the lifting part 54. The lifting part 54 abuts against the bottom of the partition part 51, so that the partition part 51 will not sag under force, thereby improving the partition stability of the partition part 51.

[0058] Furthermore, refer to Figure 2The partition 51 shown is divided into a partition section 513 and an adjustment section 514. An adjustment section 514 is provided between two adjacent partition sections 513. When the partition 51 uses a tension spring, the partition section 513 can be a tension spring and the adjustment section 514 can be a straight steel wire, so that there is a short section of straight steel wire between adjacent tension springs. The straight steel wire abuts against the lifting part 54 to prevent the spiral structure of the tension spring from moving randomly.

[0059] refer to Figure 2 and Figure 5 As shown, the lifting part 54 has a lifting opening 541, and the adjusting section 514 is located inside the lifting opening 541. The adjusting section 514 is provided with limiting protrusions 5141 at preset distances. The limiting protrusions 5141 are engaged with the lifting opening 541. The size of the limiting protrusions 5141 is larger than that of the lifting opening 541, so they will be locked by the lifting opening 541. The adjusting section 514 is provided with multiple limiting protrusions 5141, so that the adjusting section 514 between adjacent limiting protrusions 5141 can be locked into the lifting opening 541. By adjusting the position of the adjusting section 514 at the lifting opening 541 by different limiting protrusions 5141, the pulling position of the dividing part 51 can be adjusted.

[0060] Furthermore, the lifting port 541 of a single lifting part 54 can be provided in two places, and the adjusting section 514 can bypass the two lifting ports 541 and be fixed by the limiting protrusion 5141, thereby making it convenient to adjust the partitions 51 on both sides.

[0061] In some embodiments, at least one set of separating components 5 is provided. When there are multiple sets, they are spaced apart in the vertical direction. Providing multiple separating components 5 can enable the yarn to be separated at a certain distance, allowing the yarn to be transported in a more orderly manner and avoiding the situation where the yarn is deviated due to the influence of airflow, humidity, etc. because the interval span is too long.

[0062] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
