Description

Technical Field

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

[0002] Textile machinery is a general term for various machines and equipment that process natural or chemical fibers into textiles. It covers a series of processes from fiber pretreatment, spinning, weaving to fabric dyeing and finishing. Its performance and technical level have a key impact on the quality, production efficiency and production cost of textiles, and drive the progress and transformation of the textile industry.

[0003] In textile machinery, when guiding yarn, in order to avoid the entanglement that can easily occur when multiple strands of yarn are guided at the same time, the existing yarn guiding device arranges several guiding holes in an array to allow the yarn to pass through the through holes separately, so as to realize the separate transport of the yarn strands. However, there are certain sharp edges at the ends of the through holes, which can easily cause severe wear on the yarn during the yarn guiding process. Utility Model Content

[0004] The purpose of this invention is to provide a yarn guiding device for textile machinery, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A yarn guiding device for textile machinery includes a roller body. Several guide rings are spaced apart on the outside of the roller body along its length. Each guide ring has an annular concave guide groove on its outer peripheral wall for accommodating yarn. Each guide ring can be slidably adjusted along the length of the roller body. Each guide ring is provided with a locking mechanism for locking the guide ring when it is not slidably adjusted.

[0007] Furthermore, the cross-sectional shape of the guide channel is V-shaped, and all corners of the guide channel are rounded.

[0008] Furthermore, the yarn guiding device of this textile machinery also includes a pair of mounting brackets. The two mounting brackets are arranged symmetrically and extend vertically. A shaft is coaxially fixed inside the roller body. A bearing seat is provided on the top of each mounting bracket. The two ends of the shaft are rotatably installed in the bearing seats on the corresponding sides.

[0009] Furthermore, the locking mechanism includes a slider and a locking bolt. A groove is provided on the outer peripheral surface of the roller body, and the groove extends along the length of the roller body. A slider is fixed on the inner edge wall of each guide ring. Each slider is fitted into the groove in a matching sliding fit. Each slider is provided with a vertical through threaded hole. A locking bolt is screwed into each threaded hole with matching threads. The end of the locking bolt abuts against the inner wall of the groove.

[0010] Furthermore, the mounting bracket consists of an upper top frame and a lower base frame. Two bearing seats are respectively installed on the top of the corresponding top frame. One side of the base frame has a vertically extending side groove, in which a vertically extending telescopic cylinder is installed. The telescopic end of the telescopic cylinder is fixed to the bottom end of the top frame on the same side.

[0011] Furthermore, a sliding hole is provided on the top of the base frame on the side away from the telescopic cylinder, and a vertically extending sliding rod is slidably inserted into the sliding hole, with the top of the sliding rod fixed to the bottom of the top frame on the same side.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0013] By mounting multiple guide rings on the roller body and setting guide grooves on each guide ring, each yarn is placed in the corresponding guide groove, realizing the stranded guidance of the yarn. The guide grooves have no sharp edges, so they will not cause wear to the yarn during guidance.

[0014] The V-shaped cross-section of the guide groove can accommodate yarns of different thicknesses, making it highly versatile. The corners of the guide groove are rounded to eliminate sharp edges and further reduce wear on the yarn.

[0015] Each guide ring can slide and adjust along the length of the roller body, which can adjust the guide spacing between two adjacent yarns to meet processing needs. When not sliding, the guide ring can be locked by the locking mechanism to prevent the guide ring from shifting randomly, so as to fix and maintain the yarn guide position and spacing.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0023] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Example 1

[0024] Please see Figures 1-4 The present invention provides a yarn guiding device for textile machinery, comprising a roller body 1, wherein a plurality of guiding rings 2 are spaced apart on the outside of the roller body 1 along its length direction, and each guiding ring 2 has an annular concave guiding groove 21 on its outer peripheral wall for accommodating yarn. The guiding rings 2 are made of polyoxymethylene material with a wear resistance coefficient ≤0.3 and good self-lubricating properties.

[0025] Each yarn is placed in its corresponding guide groove 21 to achieve yarn stranding and guiding. The guide groove 21 has no sharp edges, so it will not cause wear to the yarn during guiding. The cross-sectional shape of the guide groove 21 is V-shaped, and the included angle of the V-shape is 55°-60°. In this application, it is preferably 60°, which can accommodate yarns of different thicknesses. That is, the finer yarn sinks deeper in the guide groove 21, and the thicker yarn sinks closer to the outer peripheral wall of the guide ring 2. It has high versatility. In addition, the corners of the guide groove 21 are all rounded to eliminate the sharp edges at the corners of the guide groove 21, further reducing wear on the yarn.

[0026] Each guide ring 2 can be slidably adjusted along the length of the roller body 1 to adjust the guide spacing between adjacent yarns to meet processing requirements. In addition, each guide ring 2 is equipped with a locking mechanism 4 to lock the guide ring 2 when not sliding, thereby preventing the guide ring 2 from shifting arbitrarily during non-sliding adjustment, and thus fixing and maintaining the yarn guide position and spacing.

[0027] Specifically, the locking mechanism 4 includes a slider 41 and a locking bolt 43. A groove 11 is provided on the outer peripheral surface of the roller body 1. The groove 11 extends along the length of the roller body 1. A slider 41 is fixed on the inner edge wall of each guide ring 2, that is, the slider 41 and the guide groove 21 are integrally formed.

[0028] Each slider 41 is fitted into the slide groove 11. Each slider 41 is provided with a vertical through threaded hole 42. Each threaded hole 42 is fitted with a locking bolt 43 with matching threads. The end of the locking bolt 43 abuts against the inner wall of the slide groove 11. The locking bolt 43 is an internal hex head bolt.

[0029] When it is necessary to slide and adjust the guide ring 2, loosen the locking bolt 43, and the end of the locking bolt 43 will separate from the inner wall of the slide groove 11, that is, the locking of the guide ring 2 will be released. At this time, the guide ring 2 can be slid and translated for adjustment.

[0030] After adjustment, tighten the locking bolt 43. The locking bolt 43 abuts against the inner wall of the slide groove 11 to lock the position of the guide ring 2.

[0031] Secondly, the slider 41, which is fixed on the inner edge wall of the guide ring 2, is slidably installed in the slide groove 11, which can guide and limit the translation of the guide ring 2, ensuring the smooth and stable translation process of the guide ring 2, achieving two goals at once.

[0032] The tightening torque of the locking bolt 43 is 3-5 N·m to ensure that the contact force with the inner wall of the slide groove 11 is ≥50 N, so as to prevent the guide ring 2 from sliding and deviating. Example 2

[0033] like Figure 1 and Figure 4 As shown, the differences between this embodiment and Embodiment 1 are as follows:

[0034] The yarn guiding device of this textile machinery also includes a pair of mounting brackets 3. The two mounting brackets 3 are arranged symmetrically and extend vertically. A shaft 12 is coaxially fixed inside the roller body 1. A bearing seat 13 is provided on the top of each of the two mounting brackets 3. The two ends of the shaft 12 are rotatably installed in the bearing seat 13 on the corresponding side.

[0035] Two mounting brackets 3 are used as supports to lift the roller body 1 to the required height position. The two ends of the shaft 12 inside the roller body 1 are respectively installed in the bearing seats 13 at the top of the two mounting brackets 3, realizing the rotational installation of the roller body 1 and the shaft 12. This enables the rotational conveying of the yarn by the guide ring 2 and the guide groove 21, effectively reducing friction between the yarn and the guide ring 2, further reducing wear, and ensuring a smoother yarn conveying process.

[0036] Specifically, the mounting bracket 3 consists of an upper top frame 32 and a lower base frame 31. The two bearing seats 13 are respectively installed on the top of the corresponding top frame 32, realizing the split design of the mounting bracket 3.

[0037] One side of the base frame 31 has a vertically extending side groove 311, and a vertically extending telescopic cylinder 33 is installed in the side groove 311. The telescopic end of the telescopic cylinder 33 is fixed to the bottom end of the top frame 32 on the same side.

[0038] The top of the base frame 31 on the other side is provided with a sliding hole 312, and a vertically extending slide rod 321 is slidably inserted into the sliding hole 312. The top end of the slide rod 321 is fixed to the bottom end of the top frame 32 on the same side.

[0039] The telescopic cylinder 33 extends and retracts, which can drive the top frame 32 on the same side to be raised and lowered, while the top frame 32 on the other side is raised and lowered synchronously, thereby realizing the height adjustment of the roller body 1 so as to adjust the yarn feeding height. During the lifting and lowering adjustment, the slide rod 321 slides synchronously in the slide hole 312, which plays a guiding and limiting role.

[0040] The telescopic cylinder 33 is hidden in the side groove 311, which provides a certain anti-collision protection for the telescopic cylinder 33. The telescopic cylinder 33 can be a linear drive mechanism such as an electric cylinder, hydraulic cylinder, pneumatic cylinder or screw cylinder.

[0041] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art. Furthermore, the specific structure, model and coefficient index of all its components are its own technology. As long as it can achieve its beneficial effect, it can be implemented. Therefore, it will not be described in detail.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
