Based on this, the mandrel is placed on the textile machine, and the yarn is wound around the roller body. During the rotation of the roller body, the yarn is guided.

[0004] However, there are many problems with the current guide rollers. For example, after the guide rollers have been used on the machine for a long time, the roller body may fly off due to mechanical fatigue accumulation, resulting in insufficient structural stability. Therefore, it is necessary to improve the existing technology.

[0005] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

[0035] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] In the description of this utility model, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component that is centrally positioned therein. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be a component that is centrally positioned therein.

[0037] Furthermore, terms such as "long," "short," "inner," and "outer" indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings. They are used only for the convenience of describing this utility model and do not indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of this utility model.

[0038] The following is in conjunction with the appendix Figures 1-7 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0039] Example 1

[0040] Please refer to Figure 1 and Figure 2 This utility model provides a yarn guide wheel structure, which mainly includes a wheel body 1, a bearing 2, and a spindle 3.

[0041] The mandrel 3 is usually mounted on the frame of the yarn guiding device to support the bearing 2 and the mandrel 3. Depending on the actual setup requirements, the mandrel 3 can be a straight structure or a bent structure. The specific structure of the mandrel 3 is not limited here. In this embodiment, the mandrel 3 with a bent structure is used as an example. Based on this, the wheel 1 is rotatably connected to the mandrel 3 through the bearing 2. In the specific setup, the inner ring of the bearing 2 is first fixedly connected to one end of the mandrel 3, and the outer ring of the bearing 2 is connected to the wheel 1. In this way, the wheel 1, the bearing 2 and the mandrel 3 are connected as a whole, and the wheel 1 can be rotatably mounted on the mandrel 3 through the bearing 2.

[0042] It should be explained that the term "connection" here can be understood as either a direct connection or an indirect connection. The specific connection method can be adjusted according to the actual setup requirements. In this embodiment, the connection between bearing 2 and wheel 1 is an indirect connection. The specific connection method between wheel 1 and bearing 2 will be described in detail below, and no specific restrictions will be made here.

[0043] Meanwhile, the wheel body 1 is used to guide the yarn. In this embodiment, a guide recess 11 extending circumferentially along the wheel body 1 is provided in the middle of the wheel body 1. The guide recess 11 makes one side of the wheel body 1 form a V-shaped cross-sectional structure. At this time, the guide recess 11 can accommodate the yarn, making it less likely for the yarn to come loose from the wheel body 1 during the transmission process.

[0044] In other embodiments, the number of guide recesses 11 can be set in multiple groups at intervals on the wheel body 1, so that multiple yarns can be guided. In addition, in other embodiments, the guide recesses 11 can also adopt a cross-sectional structure with a concave profile, such as trapezoidal or semi-circular. The structure of the wheel body 1 itself is not limited here. Any wheel body 1 structure that can guide the yarn can be tried.

[0045] Based on the above configuration, in order to prevent dust and yarn from getting tangled in the bearing 2 when the wheel 1 rotates, and to prevent the wheel 1 from loosening from the bearing 2 under long-term use conditions, the yarn guide wheel structure disclosed in this embodiment also includes an isolation component 4.

[0046] Continue to refer to Figure 1 and Figure 2 The wheel body 1 has a mounting part 12. It is understood that the mounting part 12 is located at the middle position of the wheel body 1, and the mounting part 12 can be a through hole, a blind hole, a through groove or a blind groove. The mounting part 12 is mainly used to provide mounting for the bearing 2 so that the bearing 2 is built into the inside of the wheel body 1.

[0047] Based on this, the mounting part 12 is designed with an opening on at least one side of the wheel body 1, according to the selection of its actual structure. On the one hand, this arrangement facilitates the assembly of the bearing 2 into the wheel body 1, and on the other hand, it also facilitates the subsequent provision of barrier protection by the isolation component 4. Therefore, the specific outline of the mounting part 12 is not limited in this embodiment. In this embodiment, the mounting part 12 is provided with a through-hole structure and has openings on opposite sides of the wheel body 1.

[0048] Reference Figure 2 Based on the above structural configuration, the bearing 2 is located inside the mounting portion 12, and the isolation component 4 covers the opening of the mounting portion 12. The isolation component 4 is fixed to the wheel body 1 by interlocking grooves 7 and snap rings 6. At this time, the isolation component 4 can abut against the bearing 2, thereby limiting the bearing 2 within the mounting portion 12. Under long-term use, the bearing 2 is less likely to loosen from the wheel body 1. Furthermore, the isolation component 4 can also prevent external dust, yarn, and other debris from entering the mounting portion 12, thus preventing such debris from entering the bearing 2. This reduces the possibility of the bearing 2 jamming, optimizing and improving structural stability.

[0049] Furthermore, in order to satisfy the connection relationship between the spindle 3 and the bearing 2, a clearance hole 5 is also opened through the isolation component 4. The opening size of the clearance hole 5 is not smaller than the size of the spindle 3. This allows the spindle 3 to pass through the clearance hole 5, thereby enabling the spindle 3 to still provide support for the bearing 2 and the wheel body 1 under the condition of setting the isolation component 4, thus meeting the working conditions requirements under actual use conditions.

[0050] Optionally, the opening size of the clearance hole 5 should not be too large, otherwise dust can easily enter the mounting part 12. Therefore, in one embodiment, the opening size of the clearance hole 5 can be adapted to the size of the mandrel 3, so that the hole wall of the clearance hole 5 abuts against the mandrel 3, thereby reducing the possibility of dust and yarn entering the bearing 2. In another embodiment, the opening size of the clearance hole 5 can also be slightly larger than the size of the mandrel 3. For example, the opening radius of the clearance hole 5 can be set to no more than 0.1 mm of the radius of the mandrel 3, so that a gap can be formed between the clearance hole 5 and the mandrel 3. The gap, while isolating larger dust particles, also prevents the wall of the clearance hole 5 from contacting the spindle 3, reducing friction and facilitating the rotation of the wheel 1. It is understood that the opening size of the clearance hole 5 can be adjusted according to the actual working environment requirements and the thickness of the yarn. In this embodiment, the specific size of the clearance hole 5 is not limited. In addition, in another embodiment, a sealing ring can be added to the wall of the clearance hole 5 to block the gap between the spindle 3 and the isolation component 4, thus also satisfying the blocking effect during use.

[0051] Continue to refer to Figure 2To achieve a blocking effect, in this embodiment, the isolation component 4 includes a first dust cover 41 and a second dust cover 42. The first dust cover 41 and the second dust cover 42 respectively cover the openings on both sides of the mounting part 12. In a specific setting, the outer edge dimensions of the first dust cover 41 and the second dust cover 42 are both larger than the opening size of the mounting part 12, so that the opening of the mounting part 12 can be covered in all directions.

[0052] Optionally, depending on actual needs, the clearance hole 5 can be provided on the first dust cover 41 or the second dust cover 42. There is no restriction on the specific location of the clearance hole 5. In this embodiment, the clearance hole 5 is provided on the second dust cover 42.

[0053] In order to stably cover the opening of the mounting portion 12 with the first dust cover 41 and the second dust cover 42, in this embodiment, the first dust cover 41 has a first extension 411, which is located inside the first dust cover 41 and extends into the mounting portion 12, and the second dust cover 42 has a second extension 421, which is located inside the second dust cover 42 and extends into the mounting portion 12.

[0054] Understandably, both the first extension 411 and the second extension 421 are typically cylindrical. The first dust cover 41 is integrally formed with the first extension 411, and the second dust cover 42 is integrally formed with the second extension 421. The opening profile of the first extension 411 is adapted to the mounting portion 12, thereby enabling it to abut and be positioned against the wheel 1. Furthermore, the size profile of the second extension 421 is adapted to the inner edge opening profile of the first extension 411, allowing the first extension 411 and the second extension 421 to be interlocked to ensure good structural stability.

[0055] Meanwhile, the first extension 411 and the second extension 421 are fixedly connected. In this embodiment, grooves 7 are respectively provided on the first extension 411 and the second extension 421, and the two grooves 7 are arranged opposite to each other. The retaining spring 6 is embedded in the two opposite grooves 7. Specifically, the retaining spring 6 is a C-shaped retaining spring 6. When the retaining spring 6 is installed, annular groove structures can be provided on the first extension 411 and the second extension 421 respectively. The two grooves 7 are arranged opposite to each other, and the retaining spring 6 is embedded in the two grooves 7 to achieve a fixed connection between the first extension 411 and the second extension 421. At this time, the first dust cover 41 and the second dust cover 42 are fixed to each other and clamped and installed on the wheel body 1. At this time, although the grooves 7 and the retaining spring 6 are provided on the isolation component 4 itself, the isolation component 4 is fixed on the wheel body 1 by clamping, so that the isolation component 4 is not easy to loosen and the structure is stable.

[0056] Furthermore, under these conditions, the wheel body 1 is indirectly connected to the bearing 2 via the isolation component 4. Specifically, in this embodiment, when the bearing 2 is installed, its outer ring is fixedly installed on the inner edge of the first extension 411. At this time, since the isolation component 4 is fixed to the wheel body 1 by clamping, the isolation component 4 will also rotate when the wheel body 1 rotates, thereby providing indirect rotational guidance for the wheel body 1. Therefore, the wheel body 1 is indirectly connected to the bearing 2 via the isolation component 4.

[0057] Continue to refer to Figure 3 To further improve the structural stability of the guide roller, a first limiting protrusion 8 and a second limiting protrusion 9 are also provided on the mandrel 3. The first limiting protrusion 8 and the second limiting protrusion 9 are spaced apart. At this time, by placing the bearing 2 between the first limiting protrusion 8 and the second limiting protrusion 9, the first limiting protrusion 8 and the second limiting protrusion 9 abut against the opposite sides of the bearing 2 respectively. Under the support of the first limiting protrusion 8 and the second limiting protrusion 9, the bearing 2 is not easy to loosen from the mandrel 3, and the structural stability is further optimized and improved.

[0058] Optionally, in one embodiment, the first limiting protrusion 8 is located at the end of the mandrel 3, and the first limiting protrusion can be formed into a flared structure by riveting, thus providing a limiting effect on one side of the bearing 2; at the same time, the second limiting protrusion 9 is closer to the middle section of the mandrel 3 than the first protrusion. The second limiting protrusion 9 is an integrally formed toothed structure, and it has a positioning plane on the side facing the bearing 2, thus providing a limiting and positioning effect on the other side of the bearing 2. When installing the bearing 2, it is only necessary to fit the bearing 2 onto the mandrel 3 so that the bearing 2 abuts against the positioning plane. At this time, the bearing 2 reaches the installation position. Then, by riveting and flaring the first limiting protrusion 8, the bearing 2 is fixedly installed under the bidirectional positioning action of the first limiting protrusion 8 and the second limiting protrusion 9. The installation process is efficient and reliable.

[0059] The implementation principle of this embodiment is as follows: by placing the bearing 2 inside the mounting location, the bearing 2 can be located inside the wheel body 1. At this time, the openings on both sides of the mounting part 12 are closed by the first dust cover 41 and the second dust cover 42, which can restrict the wheel body 1 from falling off and prevent debris from entering the bearing 2, making the guide wheel run more smoothly and stably.

[0060] Example 2:

[0061] Based on Embodiment 1, features not explained in this embodiment will be explained using the methods in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is that the first dust cover 41, the second dust cover 42, and the bearing 2 are arranged differently.

[0062] Among them, reference Figure 4 In this embodiment, the first dust cover 41 also has a first extension 411, and the second dust cover 42 also has a second extension 421. However, the difference is that the first dust cover 41 and the second dust cover 42 are respectively fixedly mounted on the wheel body 1. Based on this setting, the openings on both sides of the mounting part 12 can also be sealed to achieve a sealing effect.

[0063] Furthermore, when configuring the first dust cover 41 and the second dust cover 42, grooves 7 can be provided on the first dust cover 41 and the wheel body 1 respectively, with the two grooves 7 facing each other, and the retaining spring 6 embedded in the two facing grooves 7; alternatively, grooves 7 can also be provided on the second dust cover 42 and the wheel body 1 respectively, with the two grooves 7 facing each other, and the retaining spring 6 embedded in the two facing grooves 7. Based on the above configuration, at least three combination assembly methods between the first dust cover 41 and the second dust cover 42 can be obtained:

[0064] 1. In the first method, the first dust cover 41 and the wheel body 1 are fixedly connected by a retaining spring 6. The retaining spring 6 is set in the same way as in embodiment one, and also adopts a C-shaped retaining spring 6 structure. The difference from embodiment one is that in this embodiment, grooves 7 need to be set on the first extension 411 and the wheel body 1 respectively. The two grooves 7 are arranged opposite to each other and the retaining spring 6 is embedded in the two grooves 7 to achieve a fixed connection between the first dust cover 41 and the wheel body 1. At the same time, the second dust cover 42 and the wheel body 1 can be fixedly connected by other forms of connection structure besides the retaining spring 6, which will not be described in detail here.

[0065] 2. In the second method, the second dust cover 42 is fixedly connected to the wheel body 1 by a snap ring 6. Similarly, grooves 7 for the snap ring 6 to be assembled need to be opened at the corresponding positions of the second extension 421 and the wheel body 1. The specific setting method will not be described in detail here. At the same time, the first dust cover 41 and the wheel body 1 can be connected by other forms of connection structure besides snap ring 6 connection, so that the openings on both sides of the mounting part 12 can also be sealed and covered.

[0066] 3. In the third combination, the first dust cover 41 is fixedly connected to the wheel body 1 by a retaining spring 6, and the second dust cover 42 is fixedly connected to the wheel body 1 by a retaining spring 6. Under this condition, two grooves 7 need to be opened on the wheel body 1 respectively, and grooves 7 are respectively set on the first extension 411 and the second extension 421. By pairing them in pairs, the two retaining springs 6 are installed into the two sets of paired grooves 7 to achieve the fixed installation of the first dust cover 41 and the second dust cover 42, which can also seal the opening of the mounting part 12.

[0067] In summary, regardless of the connection method between the first dust cover 41 and the wheel body 1, or the connection method between the second dust cover 42 and the wheel body 1, or the combination method of the above two sets of structures, any fixing method that can seal the openings on both sides of the mounting part 12 should be included within the same scope of interpretation of this application.

[0068] It should be explained that the arrangement of bearing 2 in this embodiment is different from that in embodiment one. Specifically, in this embodiment, bearing 2 and wheel 1 are fixed to each other by direct connection. This is equivalent to setting bearing 2 between the first dust cover 41 and the second dust cover 42, and the outer ring of bearing 2 is interference-fitted or overfitted with the mounting part 12 to complete the setting of bearing 2. Under the guidance of bearing 2, wheel 1 can rotate smoothly.

[0069] The implementation principle of this embodiment is as follows: the groove 7 and the snap ring 6 play a direct fixing role. By fixing the first dust cover 41 to the wheel body 1 and fixing the second dust cover 42 to the wheel body 1, the opening of the mounting part 12 can also be closed, which can restrict the wheel body 1 from falling off and restrict debris from entering the bearing 2, making the guide wheel run more smoothly and stably.

[0070] Example 3:

[0071] Based on Embodiment 1 and Embodiment 2, features not explained in this embodiment are explained using the methods in Embodiment 1 and Embodiment 2, and will not be repeated here. The difference between this embodiment and Embodiment 1 and Embodiment 2 is that the mounting part 12 in this embodiment is open on one side of the wheel body 1 and closed on the other side of the wheel body 1.

[0072] Based on this, refer to Figure 5 In this embodiment, a blind hole structure is adopted. When the opening of the mounting part 12 is closed, the isolation component 4 includes a third dust cover 43. The structure of the third dust cover 43 is similar to that of the first dust cover 41 and the second dust cover 42. A third extension 431 is provided inside the third dust cover 43, and the third extension 431 extends into the mounting part 12.

[0073] Based on this, the third dust cover 43 is fixedly connected to the wheel body 1 and covers the opening of the mounting part 12. Specifically, the third dust cover 43 is fixedly connected to the wheel body 1 by a retaining spring 6. When setting the retaining spring 6, it is only necessary to set a groove 7 on the wheel body 1 and the third extension part 431 respectively. The two grooves 7 are set opposite to each other, and the retaining spring 6 is embedded in the two opposite grooves 7.

[0074] The implementation principle of this embodiment is as follows: Based on the above structural settings, it can also prevent foreign objects from entering the bearing 2 and prevent the wheel 1 from loosening, and the structure is simpler and the manufacturing cost is relatively lower.

[0075] Example 4:

[0076] Based on Embodiment 1, Embodiment 2, and Embodiment 3, features not explained in this embodiment are explained using the methods described in Embodiment 1, 2, and 3, and will not be repeated here. The difference between this embodiment and Embodiment 1, Embodiment 2, and Embodiment 3 is that the groove 7 and the retaining ring 6 can be replaced by other equivalent connecting structures.

[0077] In one embodiment, the isolation component 4 is connected to the wheel body 1 via a resilient latch structure. Specifically, refer to... Figure 6 Taking the assembly structure of Embodiment 1 as an example, an elastic hook 1001 is provided on the first dust cover 41, and correspondingly, a snap-fit ​​groove 1002 is provided on the second dust cover 42 to engage with the elastic hook 1001. At this time, by movably snapping the elastic hook 1001 into the snap-fit ​​groove, the first dust cover 41 and the second dust cover 42 can be connected to each other, thereby realizing the connection between the isolation component 4 and the wheel 1.

[0078] It is understandable that in Embodiments 2 and 3, any connection part using the groove 7 and the snap ring 6 can be replaced with the elastic hook 1001 and the snap-fit ​​groove 1002. Thus, by using the elastic snap hook structure, the interconnection between components can also be achieved. Therefore, similar elastic snap hook structures should be regarded as equivalent replacements for the snap ring 6 and the groove 7.

[0079] Furthermore, in another embodiment, the isolation component 4 is connected to the wheel body 1 via a threaded structure. Specifically, refer to... Figure 7 Similarly, taking the assembly structure in Embodiment 1 as an example, an external thread 1003 is provided on the first dust cover 41, and correspondingly, an internal thread 1004 is provided on the second dust cover 42 that is threadedly connected to the external thread 1003. At this time, by combining the external thread 1003 and the internal thread 1004 together, the mutual connection between the first dust cover 41 and the second dust cover 42 can be realized, thereby realizing the mutual connection between the isolation component 4 and the wheel body 1.

[0080] It is understandable that in Embodiments 2 and 3, any connection part using the groove 7 and the snap ring 6 can be replaced with a threaded structure. Thus, by using a threaded structure, the interconnection between components can also be achieved. Therefore, similar threaded connection methods should be regarded as equivalent replacements for the snap ring 6 and the groove 7.

[0081] In summary, the groove 7 and snap ring 6 in Embodiments 1, 2 and 3 can be replaced with an elastic snap hook structure or a threaded structure. Any replacement scheme that can achieve a fixed connection can be tried and should be included in the equivalent means of this solution.

[0082] Example 5:

[0083] This embodiment discloses a yarn guiding device, including a device body and any one of the yarn guiding wheel structures in Embodiment 1, Embodiment 2, Embodiment 3, and Embodiment 4. The yarn guiding wheel structure is disposed on the device body. By improving the yarn guiding wheel structure, the yarn guiding device is also optimized and improved, and the yarn guiding process is more stable.

[0084] It should be explained that the device body referred to here can be different types of functional devices in a loom, such as warp knitting, weft knitting, flat knitting, crochet knitting, glove knitting, etc. The yarn guide wheel structure can be combined with any functional device that needs to pull the yarn. There are no restrictions on the specific model and type of the device body. Regardless of the type of device body adopted, it should be included in the same interpretation.

[0085] Therefore, the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
