Description

Technical Field

[0001] This application relates to the technical field of textile machinery, and specifically to a yarn guiding device for textile machinery. Background Art

[0002] Textile machinery refers to various mechanical equipment required to process natural fibers or chemical fibers into textiles. During the use of textile machinery, a yarn guide is needed to guide the yarn, so as to accurately place the yarn on the knitting needles and ensure the smooth progress of knitting.

[0003] For example, the patent with the publication number CN118753914 A specifically discloses a yarn guiding device for textile machinery. The patent includes a support base, on both ends of which a first guide roller and a second guide roller are respectively rotatably connected. A reciprocating spiral groove is provided on the first guide roller. Both ends of the first guide roller are elastically installed with adjusting discs through elastic adjusting components. The distance between the two adjusting discs can be adjusted through the elastic adjusting components. By adopting the above structures such as the reciprocating spiral groove and the adjusting discs, when the yarn passes through the first guide roller from the winding shaft, the yarn slides in the reciprocating spiral groove, so that under the action of the reciprocating spiral groove, the jitter area is reduced, achieving the purpose of reducing the jitter amplitude of the yarn after it breaks away from the winding shaft; by adjusting the distance between the two adjusting discs, the left - right movement amplitude of the yarn on the first guide roller can be further adjusted; the self - adaptive adjustment of the jitter amplitude of the yarn is realized by using two wire guide rollers, thus avoiding situations such as yarn jumping, abrasion, and breakage when the yarn contacts the yarn guiding device after breaking away from the yarn roll.

[0004] During the implementation of the above patent, when the yarn breaks away from the yarn guide roller, the end of the yarn will be in a free state. At this time, if the non - tensioned yarn is wound on the winding roller, it may be difficult to wind the end of the yarn, resulting in the slack of the end yarn. The end slack may cause the wound yarn to become loose, and thus it may be necessary to re - wind or fix it, increasing the operation time and labor cost and reducing the production efficiency. Therefore, it is necessary to provide a yarn guiding device for textile machinery to solve the above problems.

[0022] It should be noted that, without conflict, the embodiments and features in the embodiments of this application can be combined with each other. The following will describe this application in detail with reference to the drawings and in combination with the embodiments

[0023] In order to enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application Embodiment 1

[0024] This embodiment mainly elaborates on the basic structure and working principle of the yarn guiding device of textile machinery. Specifically As Figures 1 - 2 shown, this application provides a yarn guiding device for textile machinery, including a support base 1. Both ends of the support base 1 are fixedly installed with side plates 11. A winding mechanism 2 is arranged on the two groups of side plates 11, and the winding mechanism 2 is used for winding yarn

[0025] The winding mechanism 2 includes a winding motor 21 fixedly installed on the side plate 11. The output end of the winding motor 21 is fixedly installed with a winding shaft 22. The winding shaft 22 is installed on both groups of side plates 11 by bearings, so that the winding shaft 22 can be driven to rotate synchronously by the winding motor 21

[0026] At the same time, a winding roller 23 is fixedly installed on the winding shaft 22. The winding roller 23 is suitable for winding yarn, and then the winding operation of the yarn is carried out

[0027] As Figure 1 and Figure 3As shown in the figure, a first yarn guiding mechanism 3 is further provided on the two groups of side plates 11. The first yarn guiding mechanism 3 includes a first yarn guiding roller 31 installed on the two groups of side plates 11 through bearings. A spiral groove 32 is formed in the middle position of the first yarn guiding roller 31. The spiral groove 32 is in a reciprocating spiral state, so that the yarn passing through the first yarn guiding roller 31 slides in the spiral groove 32. Under the action of the spiral groove 32, the jitter area of the yarn is reduced, and it is not easy to separate from the first yarn guiding roller 31, thereby achieving the purpose of reducing the jitter amplitude of the yarn.

[0028] At the same time, threads (not shown in the figure) are provided at both ends of the first yarn guiding roller 31. Nuts 35 are spirally installed on the threads. At the same time, a first spring 34 is fixedly installed inside the nut 35. The first spring 34 is sleeved on the first yarn guiding roller 31. At the same time, a first retaining ring 33 is fixedly installed at the end of the first spring 34 away from the nut 35. The first retaining ring 33 is slidably installed with the first yarn guiding roller 31, so that a first gap (not marked in the figure) for guiding the yarn is formed between the two first retaining rings 33. The first gap can further adjust the moving amplitude of the yarn on the first yarn guiding roller 31, and the width of the first gap can be adjusted widely through the nut 35. It should be noted that to adjust the width of the first gap, the side wall of the first retaining ring 33 needs to be adjusted to the reciprocating intersection of the spiral groove 32, so as to ensure that the yarn smoothly changes direction and moves left and right along the middle part of the first yarn guiding roller 31 when passing through the spiral groove 32. At the same time, the first spring 34 makes the first retaining ring 33 avoid hard contact with the yarn, playing a certain protective role for both the first retaining ring 33 itself and the yarn.

[0029] As Figures 1 - 2 and Figures 4 - 5 shown in the figure, a second yarn guiding mechanism 4 is provided between the first yarn guiding mechanism 3 and the winding mechanism 2. The second yarn guiding mechanism 4 is used for further guiding the yarn. The second yarn guiding mechanism 4 includes a second yarn guiding roller 41 installed on the two groups of side plates 11 through bearings. Fixed rings 44 are fixedly installed at both ends of the second yarn guiding roller 41. A second spring 42 is fixedly installed inside the fixed ring 44. The second spring 42 is sleeved on the second yarn guiding roller 41.

[0030] At the same time, a second retaining ring 43 is fixedly installed at the end of the second spring 42 away from the fixed ring 44. A second gap (not marked in the figure) for guiding the yarn is formed between the two second retaining rings 43, so as to further guide the yarn through the second gap, enabling the yarn to adaptively adjust the jitter amplitude by using the first gap and the second gap during the wire guiding process, thus avoiding situations such as wire jumping, abrasion, and breakage when the yarn contacts the yarn guiding equipment. At the same time, the setting of the second spring 42 makes the yarn avoid hard contact with the second retaining ring 43, playing a certain protective role for both the second retaining ring 43 and the yarn.

[0031] And an inclined surface 431 is provided inside the second retaining ring 43. The inclined surface 431 can concentrate the yarn with small-amplitude jitter into the second gap, thereby ensuring the wire guiding function of the second gap, shrinking the moving range of the yarn, and finally achieving the effect that the yarn advances in a straight line.

[0032] As Figures 1 - 2 and Figure 5 shown, a tensioning mechanism 5 is provided between the first yarn guiding mechanism 3 and the second yarn guiding mechanism 4. The tensioning mechanism 5 includes a tensioning motor 51 fixedly installed at the top end of the side plate 11. The output end of the tensioning motor 51 is fixedly installed with a lead screw 54. At the same time, a square groove 12 is provided on the side plate 11, and the bottom of the lead screw 54 is rotatably installed with the bottom end of the square groove 12, so that the lead screw 54 can rotate driven by the tensioning motor 51; At the same time, a bearing seat 53 is drivingly arranged on the lead screw 54. The bearing seat 53 is slidably installed with the square groove 12, so that when the lead screw 54 rotates, the bearing seat 53 can be driven to move in the vertical direction.

[0033] And a tensioning roller 52 is installed on two groups of bearing seats 53. The position of the tensioning roller 52 is lower than the positions of the first yarn guiding roller 31 and the second yarn guiding roller 41, so that the yarn can pass through the upper end of the first yarn guiding roller 31, then pass through the bottom of the tensioning roller 52, and then pass through the upper end of the second yarn guiding roller 41.

[0034] During the wire guiding process of the above yarn, the yarn is tensioned by the bottom of the tensioning roller 52, and the tension force can be adjusted by the tensioning motor 51, so as to adapt to different yarn guiding operations. Embodiment 2

[0035] When the yarn breaks away from the yarn guiding roller, the end yarn will be in a free state. At this time, if the non-tensioned yarn is wound on the winding roller 23, it may cause the end yarn to be difficult to wind, resulting in the slack of the end yarn. The end slack may cause the wound yarn to become loose, so it may be necessary to rewind or fix it, increasing the operation time and labor cost and reducing the production efficiency.

[0036] To solve the above problems, as Figure 2 and Figures 6 - 8 shown, a tightening mechanism 6 is provided on the support base 1. The tightening mechanism 6 is located between the winding mechanism 2 and the second yarn guiding mechanism 4, and is mainly used to tension the yarn at the end of winding.

[0037] The tightening mechanism 6 includes two groups of first sliding rails 61 fixedly installed on the support base 1. The first sliding rails 61 are arranged along the direction of the yarn guide wire. At the same time, a first slider 63 is slidably arranged on the first sliding rails 61. A slide plate 62 is fixedly installed on the first slider 63, and the slide plate 62 is adapted to slide on the first sliding rails 61 along with the first slider 63.

[0038] At the same time, a limit seat 64 is fixedly installed on the support base 1. A third spring 65 is fixedly installed between the limit seat 64 and the slide plate 62. Thus, in the initial state, under the action of the third spring 65, the slide plate 62 is in a position away from the winding mechanism 2.

[0039] Continue to refer to Figures 7 - 8 , a clamping mechanism 7 is arranged on the slide plate 62. The clamping mechanism 7 includes two groups of second sliding rails 71 fixedly arranged on the slide plate 62 along the direction perpendicular to the yarn conveying direction. Slide seats 72 are slidably arranged on the two groups of second sliding rails 71. A guide rod 74 is fixedly installed on the slide seat 72. A clamping seat 75 is slidably arranged on the guide rod 74. A fourth spring 73 is fixedly installed between the clamping seat 75 and the slide seat 72. It should be noted that a clamping groove 721 is arranged on the slide seat 72, and the clamping groove 721 is adapted to the clamping seat 75, so that the clamping seat 75 slides more stably.

[0040] At the same time, clamping rings 751 are arranged at the opposite positions of the two groups of clamping seats 75. In the initial state, the two groups of slide seats 72 approach each other, so that the two groups of clamping rings 751 form a complete ring (not marked in the figure). This ring is used to clamp the yarn. It should be noted that a thread sleeve with a diameter slightly larger than the diameter of the yarn is arranged at the end of the yarn (not shown in the figure). The diameter of the ring formed by the two groups of clamping rings 751 is larger than the diameter of the yarn and smaller than the diameter of the thread sleeve. Thus, the ring can allow the yarn to pass through, while the thread sleeve cannot pass through.

[0041] In summary, when the yarn is wound to the end, by approaching the two groups of slide seats 72, the two groups of clamping rings 751 block the thread sleeve. Since the slide plate 62 slides on the first sliding rails 61, when the thread sleeve is blocked by the clamping rings 751, the slide plate 62 can slide on the first sliding rails 61, so as to tension the yarn and make the winding of the end of the yarn more compact.

[0042] In order to enable the two groups of clamping rings 751 to move away from each other, and then enable the thread sleeve to pass through, so as to facilitate the complete winding of the yarn on the winding roller 23, as Figures 8 - 10As shown, a driving mechanism 8 is provided on the skateboard 62. The driving mechanism 8 is used to control the sliding of the sliding seat 72 on the second slide rail 71. The driving mechanism 8 includes a driving seat 85 fixedly installed on the side of the sliding seat 72. A second rack 89 is fixedly installed on the driving seat 85. At the same time, a vertical rod 82 is rotatably installed on the skateboard 62. A first gear 81 is fixedly installed at the upper end of the vertical rod 82. The first gear 81 meshes with the second rack 89. Thus, when the first gear 81 rotates, the sliding seat 72 can be driven to reciprocate on the second slide rail 71 through the second rack 89.

[0043] At the same time, a second gear 83 is fixedly installed at the bottom of the vertical rod 82, and a first rack 84 is fixedly installed on the support seat 1. The first rack 84 meshes with the second gear 83. Thus, when the skateboard 62 moves, the second gear 83 can be driven to rotate on the first rack 84, and then the first gear 81 can be driven to rotate through the vertical rod 82 to drive the sliding seat 72 to reciprocate.

[0044] In summary, in the initial state, the skateboard 62 is in a position away from the winding roller 23. At the same time, the two clamping rings 751 are closest to each other under the action of the fourth spring 73, so that the wire sleeve can be blocked. And at this time, the fourth spring 73 is in a compressed state.

[0045] When the yarn is normally wound, since the diameter of the loop formed by the two clamping rings 751 is larger than the diameter of the yarn, the yarn can pass through the loop normally without being affected.

[0046] When the yarn is wound to the end, since the end of the yarn has a wire sleeve and the diameter of the wire sleeve is larger than the diameter of the loop, the wire sleeve will abut against the clamping ring 751 and drive the skateboard 62 to move synchronously and slowly approach the winding roller 23.

[0047] During the process of the skateboard 62 approaching the winding roller 23, the second gear 83 will rotate on the first rack 84 and drive the first gear 81 to rotate synchronously. Furthermore, the two sliding seats 72 will slowly separate, and the two clamping rings 751 will gradually separate.

[0048] Because the fourth spring 73 is in a compressed state in the initial state, during the process of the two clamping rings 751 slowly separating, the fourth spring 73 slowly releases, so that the two clamping rings 751 are still in a close state. Until the fourth spring 73 returns to its free state, the two clamping rings 751 separate from each other. At this time, the diameter formed between the two clamping rings 751 will be larger than the diameter of the wire sleeve, so that the wire sleeve can pass through between the two clamping rings 751 and be wound on the winding roller 23.

[0049] Because the wire sleeve is already relatively close to the winding roller 23 at this time, the end of the yarn has been basically wound up and there will be no excessive loose state.

[0050] Furthermore, as Figure 10 shown, a driving groove 851 is formed in the driving seat 85. A separating tooth 810 is slidably disposed inside the driving groove 851. A fifth spring 811 is connected between the separating tooth 810 and the driving seat 85. In the initial state, the distance between the separating tooth 810 and the second rack 89 is equal to the pitch of the second rack 89.

[0051] Thus, when the sliding plate 62 is reset under the action of the third spring 65, the distance between the two clamping rings 751 can be adjusted by the separating tooth 810. Even if the sliding plate 62 is reset excessively (due to the inertia of the third spring 65), it will not cause excessive interference between the two clamping rings 751.

[0052] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
