Description

Technical Field

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

[0002] Textile machinery refers to various mechanical equipment used to process natural or chemical fibers into textiles. During the use of textile machinery, yarn guides are needed to guide the yarn so that it can be accurately placed on the knitting needles and ensure smooth knitting.

[0003] For example, patent CN118753914 A discloses a yarn guiding device for textile machinery. This patent includes a support base, with a first guide roller and a second guide roller rotatably connected to both ends of the support base. The first guide roller has a reciprocating spiral groove, and both ends of the first guide roller are elastically mounted with adjusting discs through elastic adjusting components. The distance between the two adjusting discs can be adjusted by the elastic adjusting components. By using the above-mentioned reciprocating spiral groove and adjusting disc structure, when the yarn passes through the first guide roller from the winding shaft, the yarn slides in the reciprocating spiral groove, thereby reducing the shaking area under the action of the reciprocating spiral groove, achieving the purpose of reducing the shaking amplitude of the yarn after it leaves the winding shaft. By adjusting the distance between the two adjusting discs, the left and right movement amplitude of the yarn on the first guide roller can be further adjusted. The two guide rollers are used to achieve adaptive adjustment of the yarn shaking amplitude, thereby avoiding situations such as skipping, wear, and breakage when the yarn comes into contact with the yarn guiding device after leaving the winding.

[0004] In the process of implementing the above-mentioned patent, when the yarn leaves the guide roller, the yarn at the tail end will be in a free state. If the yarn that is not tensioned is wound on the take-up roller, it may be difficult to wind the yarn at the tail end, resulting in slack in the yarn at the tail end. Slack at the end may cause the wound yarn to come loose, which may require rewinding or fixing, increasing operation time and labor costs and reducing production efficiency. Therefore, it is necessary to provide a yarn guiding device for textile machinery to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application. Example 1

[0044] This embodiment mainly illustrates the basic structure and working principle of the yarn guiding equipment in textile machinery, specifically:

[0045] like Figures 1-2 As shown, this application provides a yarn guiding device for textile machinery, including a support base 1, with side plates 11 fixedly installed at both ends of the support base 1. A winding mechanism 2 is provided on the two sets of side plates 11, which is used to wind up the yarn.

[0046] The winding mechanism 2 includes a winding motor 21 fixedly mounted on the side plate 11. A winding shaft 22 is fixedly mounted on the output end of the winding motor 21. The winding shaft 22 is mounted with bearings on both sets of side plates 11, so that the winding motor 21 can drive the winding shaft 22 to rotate synchronously.

[0047] Meanwhile, a take-up roller 23 is fixedly installed on the take-up shaft 22. The take-up roller 23 is suitable for winding yarn, thereby performing the take-up operation on the yarn.

[0048] like Figure 1 and Figure 3 As shown, a first yarn guiding mechanism 3 is also provided on the two sets of side plates 11. The first yarn guiding mechanism 3 includes a first yarn guiding roller 31 with bearings mounted on the two sets of side plates 11. A spiral groove 32 is provided in the middle 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 shaking area of ​​the yarn is reduced and it is not easy to detach from the first yarn guiding roller 31, thereby achieving the purpose of reducing the shaking amplitude of the yarn.

[0049] Meanwhile, threads (not shown in the figure) are provided at both ends of the first yarn guide roller 31. Nuts 35 are screwed onto these threads, and a first spring 34 is fixedly installed inside the nut 35. The first spring 34 is sleeved on the first yarn guide roller 31, and 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 guide roller 31, thereby forming a first gap (not shown in the figure) between the two sets of first retaining rings 33 to guide the yarn. This first gap can further adjust the movement of the yarn on the first yarn guide roller 31, and the width of the first gap can be adjusted by the nut 35. It should be noted that the adjustment of the width of the first gap requires adjusting the side wall of the first retaining ring 33 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 guide roller 31 when passing through the spiral groove 32. At the same time, the first spring 34 prevents the first retaining ring 33 from making hard contact with the yarn, thus providing a certain degree of protection for both the first retaining ring 33 and the yarn.

[0050] like Figures 1-2 and Figures 4-5 As shown, 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 to further guide the yarn. The second yarn guiding mechanism 4 includes a second yarn guiding roller 41 with bearings mounted on two sets of side plates 11. Both ends of the second yarn guiding roller 41 are fixedly mounted with fixing rings 44. A second spring 42 is fixedly mounted on the inner side of the fixing rings 44. The second spring 42 is sleeved on the second yarn guiding roller 41.

[0051] Meanwhile, 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) is formed between the two sets of second retaining rings 43 to guide the yarn. The yarn is further guided through the second gap, so that the yarn can adaptively adjust the yarn vibration amplitude by using the first gap and the second gap during the yarn guiding process. This avoids situations such as yarn skipping, wear, and breakage when the yarn comes into contact with the yarn guiding device. At the same time, the setting of the second spring 42 prevents the yarn from making hard contact with the second retaining ring 43, and provides a certain degree of protection for both the second retaining ring 43 and the yarn.

[0052] Furthermore, an inclined surface 431 is provided on the inner side of the second retaining ring 43. This inclined surface 431 can concentrate the yarn that is shaking slightly into the second gap, thereby ensuring the guiding function of the second gap, reducing the range of yarn movement, and ultimately achieving the effect of the yarn moving in a straight line.

[0053] like Figures 1-2 and Figure 5 As 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 on the top of the side plate 11. A lead screw 54 is fixedly installed at the output end of the tensioning motor 51. 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 under the drive of the tensioning motor 51.

[0054] Meanwhile, a bearing seat 53 is provided on the lead screw 54 for transmission. The bearing seat 53 is slidably installed with the square groove 12, so that when the lead screw 54 rotates, it can drive the bearing seat 53 to move in the vertical direction.

[0055] Tensioning rollers 52 are installed on the two sets of bearing seats 53. The tensioning rollers 52 are positioned lower than the first yarn guide roller 31 and the second yarn guide roller 41, so that the yarn can pass through the upper end of the first yarn guide roller 31, then through the bottom of the tensioning roller 52, and then through the upper end of the second yarn guide roller 41.

[0056] During the yarn guiding process described above, the yarn is tensioned by the bottom of the tensioning roller 52, and the tension can be adjusted by the tensioning motor 51 to adapt to different yarn guiding operations. Example 2

[0057] After the yarn leaves the guide roller, the yarn at the tail end will be in a free state. If the yarn that is not tensioned at this time is wound on the take-up roller 23, it may be difficult to wind the yarn at the tail end, resulting in slack in the yarn at the tail end. Slack at the end may cause the wound yarn to come loose, which may require rewinding or fixing, increasing operation time and labor costs and reducing production efficiency.

[0058] To solve the above problems, such as Figure 2 and Figures 6-8 As 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 tighten the yarn at the end of the winding.

[0059] The tightening mechanism 6 includes two sets of first slide rails 61 fixedly installed on the support base 1. The first slide rails 61 are arranged along the direction of the yarn conductor. At the same time, a first slider 63 is slidably arranged on the first slide rails 61. A slide plate 62 is fixedly installed on the first slider 63. The slide plate 62 is adapted to slide on the first slide rails 61 with the first slider 63.

[0060] Meanwhile, a limiting seat 64 is fixedly installed on the support base 1. A third spring 65 is fixedly installed between the limiting seat 64 and the slide plate 62, so that in the initial state, the slide plate 62 is in a position away from the winding mechanism 2 under the action of the third spring 65.

[0061] Continue to refer to Figures 7-8 A clamping mechanism 7 is provided on the slide plate 62. The clamping mechanism 7 includes two sets of second slide rails 71 fixedly arranged on the slide plate 62 along the direction perpendicular to the yarn conveying direction. A slide seat 72 is slidably arranged on each of the two sets of second slide 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 provided on the slide seat 72. The clamping groove 721 is adapted to the clamping seat 75, thereby making the sliding of the clamping seat 75 more stable.

[0062] Meanwhile, clamping rings 751 are provided at opposite positions of the two sets of clamping seats 75. In the initial state, the two sets of sliding seats 72 are close to each other, so that the two sets of clamping rings 751 form a complete ring (not shown in the figure). This ring is used to clamp the yarn. It should be noted that a sleeve with a diameter slightly larger than the yarn diameter is provided at the end of the yarn (not shown in the figure). The diameter of the ring formed by the two sets of clamping rings 751 is larger than the yarn diameter but smaller than the diameter of the sleeve, so that the ring can allow the yarn to pass through, but the sleeve cannot.

[0063] In summary, when the yarn is wound to the end, by bringing the two sets of slide blocks 72 closer together, the two sets of clamping rings 751 block the yarn sleeve. Because the slide plate 62 slides on the first slide rail 61, when the yarn sleeve is blocked by the clamping rings 751, the slide plate 62 can slide on the first slide rail 61, thereby tensioning the yarn and making the winding at the end of the yarn more compact.

[0064] In order to keep the two sets of clamping rings 751 away from each other, so that the yarn sleeve can pass through, and so that the yarn can be completely wound onto the take-up roller 23, as follows: Figures 8-10 As shown, a drive mechanism 8 is provided on the slide plate 62. The drive mechanism 8 is used to control the slide block 72 to slide on the second slide rail 71. The drive mechanism 8 includes a drive seat 85 fixedly installed on the side of the slide block 72. A second rack 89 is fixedly installed on the drive seat 85. At the same time, a vertical rod 82 is rotatably installed on the slide plate 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. So when the first gear 81 rotates, the slide block 72 can be driven to reciprocate on the second slide rail 71 through the second rack 89.

[0065] Meanwhile, a second gear 83 is fixedly installed at the bottom of the upright 82, and a first rack 84 is fixedly installed on the support 1. The first rack 84 meshes with the second gear 83, so that when the slide plate 62 moves, it can drive the second gear 83 to rotate on the first rack 84, and then drive the first gear 81 to rotate through the upright 82, so as to drive the slide block 72 to reciprocate.

[0066] In summary, in the initial state, the slide plate 62 is located far away from the take-up roller 23, and the two sets of clamping rings 751 are closest to each other under the action of the fourth spring 73, which can block the wire sleeve. At this time, the fourth spring 73 is in a compressed state.

[0067] When the yarn is wound normally, because the diameter of the loops formed by the two sets of clamping rings 751 is larger than the diameter of the yarn, the yarn can pass through the loops normally without being affected.

[0068] When the yarn is wound to the end, because the end of the yarn has a loop and the diameter of the loop is larger than the diameter of the ring, the loop will abut against the clamping ring 751 and drive the slide plate 62 to move synchronously and slowly approach the take-up roller 23.

[0069] As the slide plate 62 moves toward the take-up roller 23, the second gear 83 rotates on the first rack 84 and drives the first gear 81 to rotate synchronously, thereby causing the two sets of slide blocks 72 to slowly separate and the two sets of clamping rings 751 to gradually separate.

[0070] Because the fourth spring 73 is in a compressed state in the initial state, it slowly releases as the two sets of clamping rings 751 gradually separate, so that the two sets of clamping rings 751 remain close together until the fourth spring 73 returns to a free state, at which point the two sets of clamping rings 751 separate from each other. At this time, the diameter between the two sets of clamping rings 751 is larger than the diameter of the wire sleeve, so that the wire sleeve can pass through the two sets of clamping rings 751 and be wound onto the take-up roller 23.

[0071] Because the yarn sleeve is already close to the take-up roller 23 at this point, the end of the yarn has been basically wound up and there will be no excessive looseness.

[0072] Furthermore, such as Figure 10 As shown, a drive groove 851 is provided on the drive seat 85. A separation tooth 810 is slidably arranged inside the drive groove 851. A fifth spring 811 is connected between the separation tooth 810 and the drive seat 85. In the initial state, the distance between the separation tooth 810 and the second rack 89 is equal to the tooth pitch of the second rack 89.

[0073] Therefore, when the slide plate 62 is reset under the action of the third spring 65, the distance between the two sets of clamping rings 751 can be adjusted by the separation teeth 810. Even if the slide plate 62 resets excessively (due to the inertia of the third spring 65), it will not cause excessive interference between the two sets of clamping rings 751.

[0074] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
