Description

Technical Field

[0001] This application relates to the technical field of mechanical control of the spinning process, and in particular to a yarn guiding device. Background Technology

[0002] Currently, Chinese patent CN209368422U discloses an open yarn guide hook, which includes an adjusting tooth, a yarn guide ring, and a winding hook. One end of the adjusting tooth is connected to the yarn guide ring, and the adjusting tooth is arranged radially along the yarn guide ring with one end connected to the yarn guide ring. The yarn guide ring has an opening on the side away from the adjusting tooth. The winding hook includes a first winding hook and a second winding hook that extend from the two side walls of the opening to the side away from the adjusting tooth. Both the first winding hook and the second winding hook are arc-shaped, and the distance between the first winding hook and the second winding hook gradually increases from one end of the opening to the other end. The length of the first winding hook is greater than the length of the second winding hook.

[0003] Because there is an opening in the yarn guide ring, the yarn cannot enter from an angle facing the opening when passing through the yarn guide ring, otherwise the yarn guide ring cannot perform its guiding function, so its applicability is relatively low. Utility Model Content

[0004] To improve applicability, this application provides a wire guide device.

[0005] This application provides a wire guide device, which adopts the following technical solution:

[0006] A wire guide device includes a first guiding mechanism, which includes a support block, a support plate, and a first guide block. The support plate is disposed on the support block, and the first guide block is disposed on the support plate. The first guide block includes a first component block and a second component block. The first component block is spirally arranged to form a ring-shaped guiding channel, and the second component block is disposed at both ends of the first component block. The first component block is connected to the support plate, and the included angle between the two second component blocks is an obtuse angle.

[0007] By adopting the above technical solution, a single strand of yarn passes through the guide channel of the first guide block, and then the yarn passing through the guide channel is twisted together. The two second component blocks can block the yarn and reduce the phenomenon of yarn tangling together. The annular guide channel can guide the yarn at any angle, thereby improving applicability. Therefore, the first guide mechanism can guide the yarn at any angle, thereby improving applicability.

[0008] Optionally, the support plate abuts against the support block, and the support block is provided with a connecting mechanism. The connecting mechanism includes a first connecting plate, a second connecting plate, and a connecting component. The first connecting plate is fixedly connected to the second connecting plate. The first connecting plate abuts against the support block and is connected to the support block through the connecting component. The second connecting plate abuts against the support plate and is connected to the support plate through the connecting component.

[0009] By adopting the above technical solution, after the support plate abuts against the support block, the first connecting block is connected to the support block through the connecting component, and the second connecting plate is connected to the support plate through the connecting component, thereby fixing the support plate to the support block; the provided connecting mechanism facilitates fixing the support plate to the support block.

[0010] Optionally, the connecting assembly includes a connecting bolt and a connecting nut. The first connecting plate and the second connecting plate are each provided with a first through hole, and the support block and the support plate are provided with a second through hole. The end of the connecting bolt away from its own nut passes through the first through hole and the second through hole in sequence, and the connecting nut is threadedly connected to the connecting bolt passing through the second through hole.

[0011] By adopting the above technical solution, when the support plate abuts against the support block, the first connecting plate abuts against the support block, and the second connecting plate abuts against the support plate; then, one end of one connecting bolt away from its own nut passes through the first through hole on the first connecting plate and the second through hole on the support block in sequence, and the connecting nut is threadedly connected to the connecting bolt passing through the second through hole on the support block, with the nut of the connecting bolt pressing against the first connecting plate and the connecting nut pressing against the support block; then, the other end of the connecting bolt away from its own nut passes through the first through hole on the second connecting plate and the second through hole on the support plate in sequence, and the connecting nut is threadedly connected to the connecting bolt passing through the second through hole on the support plate, with the nut of the connecting bolt pressing against the second connecting plate and the connecting nut pressing against the support plate; the structure of the connecting assembly is simple and easy to operate.

[0012] Optionally, the support block has a third through hole, and a limiting block that engages with the third through hole is fixedly connected to the support plate.

[0013] By adopting the above technical solution, before the first connecting plate and the support block are connected by the connecting assembly, the end of the limiting block away from the support plate is first engaged with the third through hole, and then the first connecting plate is connected to the support block by the connecting assembly after the support plate abuts against the support block. The limiting block can position the support plate, reduce the adjustment time of the support plate, and thus improve the installation efficiency of the support plate.

[0014] Optionally, the support block is provided with a reinforcement mechanism, which includes a reinforcement block and an adjustment component. The reinforcement block is slidably disposed on the support block through the adjustment component, and the limiting block is provided with a reinforcement groove that engages with the reinforcement block.

[0015] By adopting the above technical solution, when the support plate abuts against the support block, the adjustment component drives the reinforcing block to move, so that the reinforcing block engages with the reinforcing groove on the limiting block; the set reinforcement mechanism can improve the stability of the support plate on the support block.

[0016] Optionally, the adjustment assembly includes a fixed plate, a fixed block, a first spring, and a movable block. The fixed plate is disposed on the support block, and the fixed block is disposed on the fixed plate. The fixed block has a first groove for the reinforcing block to engage. One end of the first spring is connected to the fixed block and the other end is connected to the reinforcing block. The fixed block has a clearance groove communicating with the first groove, and the movable block is disposed on the reinforcing block and can slide within the clearance groove.

[0017] By adopting the above technical solution, when it is necessary to separate the support plate from the support block, the operator moves the moving block, which drives the reinforcing block to move, so that the reinforcing block separates from the reinforcing groove on the limiting block; then the operator moves the support plate so that the end of the limiting block away from the support plate passes through the fourth through hole, thereby realizing the separation of the limiting block and the support block.

[0018] Optionally, the support block is provided with a second guiding mechanism, the second guiding mechanism including a first connecting block, a second connecting block, a second guiding block and a fixing component, the first connecting block is disposed on the support block and a guiding groove is formed on the first connecting block; the second connecting block is disposed on the first connecting block and the second guiding block is disposed on the second connecting block through the fixing component.

[0019] By adopting the above technical solution, the single yarn first passes through the guide channel of the second guide block, then through the guide groove on the first connecting block, and then through the guide channel of the first guide block; the second guide mechanism can guide the yarn that is to pass through the guide channel on the first guide block, reduce the phenomenon of yarn tangling together, and can also tension the yarn.

[0020] Optionally, the structure of the second guide block is the same as that of the first guide block. The fixing component includes a fixing screw and a fixing nut. A fourth through hole is provided on the second connecting block. The fixing screw is disposed on the first component of one of the second guide blocks, and one end of the fixing screw passes through the fourth through hole. Two fixing nuts are provided. Both fixing nuts are threadedly connected to the fixing screw, and the two fixing nuts respectively abut against the sidewalls of the second connecting block on both sides of the fourth through hole.

[0021] By adopting the above technical solution, one of the fixing nuts is first threaded onto the fixing screw, then the fixing screw passes through the fourth through hole, and the fixing nut on the fixing screw abuts against the second connecting block. Then, the other fixing nut is threaded onto the fixing screw passing through the fourth through hole and also abuts against the second connecting block. The fixed assembly not only facilitates operation and allows for quick fixing of the second guide block to the second connecting block, but also allows adjustment of the position of the second guide block relative to the support block based on the positions of the two fixing nuts on the fixing screw, thereby improving the applicability.

[0022] Optionally, a protective pad is provided on the side wall of the guide groove.

[0023] By adopting the above technical solution, the yarn will come into contact with the protective pad when passing through the guide groove, and the protective pad can protect the yarn.

[0024] Optionally, both the first and second component blocks are provided with a wear-resistant coating.

[0025] By adopting the above technical solution, since the yarn will come into contact with the first and second component blocks when passing through the guide channel, the wear-resistant coating can protect the first guide block and reduce wear.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The first guiding mechanism can guide yarns at any angle, thereby improving applicability;

[0028] 2. The second guiding mechanism can guide the yarn that is about to pass through the guiding channel on the first guiding block, reduce the phenomenon of yarn tangling together, and also provide tension to the yarn. Attached Figure Description

The first component block 131 is fixed to the support plate 12. Both the sidewalls of the first component block 131 and the second component block 132 are coated with a wear-resistant coating. In this embodiment, the wear-resistant coating is a chromium nitride coating with an ultra-low coefficient of friction and good wear resistance.

[0042] refer to Figure 2 and Figure 4 The second guiding mechanism 5 includes a first connecting block 51 fixedly connected to the support block 11. The first connecting block 51 is L-shaped, and a guide groove 511 is formed at the end of the first connecting block 51 away from the support block 11. A protective pad 6 is fixedly connected to the side wall of the guide groove 511. A second connecting block 52 is fixedly connected to the first connecting block 51. The second connecting block 52 includes a third connecting plate 521 fixedly connected to the first connecting block 51. A fourth connecting plate 522 is integrally formed at the end of the third connecting plate 521 away from the first connecting block 51. A fourth through hole is formed on the fourth connecting plate 522. A second guiding block 53 is formed on the side of the fourth connecting plate 522 away from the first connecting plate 21. The structure of the second guiding block 53 is the same as that of the first guiding block 13. The fourth connecting plate 522 is provided with a fixing component 54 connected to the second guide block 53. The fixing component 54 includes a fixing screw 541, which is integrally mounted on one of the second component blocks 132 of the second guide block 53. The end of the fixing screw 541 away from the second component block 132 passes through the fourth through hole of the fourth connecting plate 522. Two fixing nuts 542 are threadedly connected to the fixing screw 541, and the two fixing nuts 542 abut against the two side walls of the fourth connecting plate 522 respectively.

[0043] The single strand of yarn first passes through the guide channel 133 on the second guide block 53 and then through the guide groove 511 on the first connecting plate 21.

[0044] refer to Figure 2 and Figure 5The support block 11 has a second groove 112 and a third through hole 111 communicating with the second groove 112. A limiting block 3 is fixedly connected to the support plate 12. One end of the limiting block 3 away from the support plate 12 passes through the third through hole 111 and is located in the second groove 112, and the limiting block 3 is engaged with the third through hole 111.

[0045] A reinforcing mechanism 4 is provided in the second groove 112 of the support block 11. The reinforcing mechanism 4 includes an adjusting component 42. The adjusting component 42 includes a fixing plate 421 fixedly connected to the support block 11. An L-shaped fixing block 422 is fixedly connected to the fixing plate 421. A first groove 4221 is provided at the end of the fixing block 422 away from the fixing plate 421. The reinforcing block 41 is slidably connected in the first groove 4221. A reinforcing groove that engages with the reinforcing block 41 is provided on the limiting block 3. A first spring 423 is provided in the first groove 4221. One end of the first spring 423 is connected to the fixing block 422 and the other end is connected to the reinforcing block 41. A moving block 424 is fixedly connected to the reinforcing block 41. An avoidance groove 4222 is provided on the fixing block 422, which communicates with the first groove 4221 and can slide with the moving block 424.

[0046] Before the limiting block 3 passes through the third through hole 111 on the support block 11, the operator first holds the moving block 424 and then moves the moving block 424. The moving block 424 drives the reinforcing block 41 to move, and the first spring 423 will be compressed. Then, the end of the limiting block 3 away from the support plate 12 passes through the third through hole 111 on the support block 11. When the support plate 12 touches the support block 11, the moving block 424 is released. The force of the first spring 423 restoring its elastic deformation drives the reinforcing block 41 to move towards the limiting block 3, so that the reinforcing block 41 engages with the reinforcing groove on the limiting block 3.

[0047] refer to Figure 2 A connecting mechanism 2 is provided on the support block 11. The connecting mechanism 2 includes a first connecting plate 21 that abuts against the support block 11, and a second connecting plate 22 integrally provided on the first connecting plate 21. The second connecting plate 22 abuts against the support plate 12. A first through hole is provided on both the first connecting plate 21 and the second connecting plate 22, and a second through hole is provided on both the support block 11 and the support plate 12. A connecting component 23 is provided on both the first connecting plate 21 and the second connecting plate 22. The connecting component 23 includes a connecting bolt 231. The end of the connecting bolt 231 away from its own nut passes through the first through hole and the second through hole in sequence. A connecting nut 232 is threaded onto the connecting bolt 231 that passes through the second through hole.

[0048] When the support plate 12 abuts against the support block 11, the first connecting plate 21 abuts against the support block 11, the second connecting plate 22 abuts against the support plate 12, and the first through hole on the first connecting plate 21 communicates with the second through hole on the support block 11, and the first through hole on the second connecting plate 22 communicates with the second through hole on the support plate 12. Then, the end of the connecting bolt 231 in one of the connecting components 23 away from its own nut passes through the first through hole on the first connecting plate 21 and the second through hole on the support block 11 in sequence, and is located in the second groove 112 of the support block 11. Then, the connecting nut 232 is threadedly connected to the connecting bolt 231 passing through the second through hole on the support block 11, and the nut of the connecting bolt 231 abuts against the first connecting plate 21, and the connecting nut 232 abuts against the side wall of the second groove 112 on the support block 11. Then, the end of the connecting bolt 231 in the other connecting component 23 away from its own nut passes through the first through hole on the second connecting plate 22 and the second through hole on the support plate 12 in sequence. Then, the connecting nut 232 is threadedly connected to the connecting bolt 231 passing through the second through hole on the support plate 12, and the nut of the connecting bolt 231 abuts against the second connecting plate 22, and the connecting nut 232 abuts against the support plate 12.

[0049] refer to Figure 1 The third guiding mechanism 8 includes a third connecting block 81 connected to the frame 7. The structure of the third connecting block 81 is the same as that of the second connecting block 52. The third connecting block 81 is connected to the third guiding block 82 by a fixing component 54. The structure of the third guiding block 82 is the same as that of the first guiding block 13. That is, one of the second components 132 of the third guiding block 82 is installed on the fourth connecting plate 522 of the third connecting block 81 by a fixing screw 541 and two fixing nuts 542.

[0050] The implementation principle of Embodiment 1 of this application is as follows: a single strand of yarn first passes through the guide channel 133 of the second guide block 53, then through the guide groove 511 on the first connecting block 51, and then through the guide channel 133 of one of the first guide blocks 13. After multiple strands of yarn have passed through the guide channels 133 of the first guide blocks 13, they pass together through the guide channel 133 of the third guide block 82. Finally, the multiple strands of yarn that have passed through the guide channels 133 of the third guide block 82 are twisted together.

[0051] Example 2

[0052] refer to Figure 6The difference from Embodiment 1 is that the end of the limiting block 3 away from the support plate 12 has a sliding hole 31 and an adjusting hole 32 communicating with the sliding hole 31. The fixing mechanism includes a slidably connected to a stabilizing block 43 in the sliding hole 31. Two stabilizing blocks 43 are provided, and a second spring 44 is connected to each stabilizing block 43. The end of the second spring 44 away from the stabilizing block 43 is connected to the limiting block 3. A first adjusting rod 45 is hinged to each stabilizing block 43. The ends of the two first adjusting rods 45 away from the stabilizing blocks 43 are connected to an adjusting shaft, and both first adjusting rods 45 are rotatably connected to the adjusting shaft. A second adjusting rod 46 is slidably connected in the adjusting hole 32. One end of the second adjusting rod 46 is fixedly connected to the adjusting shaft, and the other end passes through the adjusting hole 32.

[0053] When the support plate 12 needs to contact the support block 11, the operator presses the two stabilizing blocks 43, so that the ends of the two stabilizing blocks 43 that are far apart from each other enter the sliding hole 31 of the limiting block 3, and the two second springs 44 are compressed. Then, the end of the limiting block 3 that is far away from the support block 11 and the two stabilizing blocks 43 pass through the fourth through hole and are located in the second groove 112 of the support block 11. When the support plate 12 contacts the support block 11, the force of the second spring 44 restoring its elastic deformation drives the stabilizing blocks 43 to move, so that the ends of the two stabilizing blocks 43 that are far apart from each other move out of the sliding hole 31, and the two second fixing blocks 422 will contact the bottom wall of the second groove 112.

[0054] When it is necessary to separate the support plate 12 from the support block 11, the operator pulls the second adjusting rod 46. The second adjusting rod 46 drives the adjusting shaft to move, which in turn drives the two first adjusting rods 45 to move. The two first adjusting rods 45 then drive the two stabilizing blocks 43 to move in opposite directions, so that the ends of the two stabilizing blocks 43 that are far apart from each other are both located within the sliding holes 31 of the limiting block 3. Then the operator removes the support plate 12, which drives the limiting block 3 to move. The limiting block 3 then drives the two stabilizing blocks 43 to move. When both stabilizing blocks 43 are no longer located within the second groove 112 and have passed through the fourth through hole, the operator releases the second adjusting rod 46.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
