[0030] 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.
[0031] 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.
[0032] 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.
[0033] The following is in conjunction with the appendix Figure 1-2 The technical solution of this utility model will be further illustrated through specific implementation methods.
[0034] Example 1:
[0035] Please refer to Figure 1 and Figure 2This utility model provides a filter sheet to prevent yarn escape, including a sheet body 1, on which a filter groove 2 is provided. One end of the filter groove 2 is close to the middle of the sheet body 1, and the other end extends to the edge of the sheet body 1.
[0036] Specifically, the filter tank 2 includes a filter section 21 and an opening section 22 connected in sequence. In this embodiment, the opening section 22 opens at the edge of the sheet 1, and the filter section 21 has a straight profile. One end of the filter section 21 is close to the middle of the sheet 1, and the other end is connected to the opening end. The filter section 21 plays the role of filtering the yarn. Specifically, the size of the gap in the filter section 21 is often related to the filtration accuracy required by the yarn during the filtration process. By embedding the yarn into the filter section 21, the yarn moves in a direction perpendicular to the sheet 1 during the yarn feeding process. At this time, the yarn scrapes off impurities through the opposite two side edges on the filter section 21, thereby realizing the yarn filtration function.
[0037] At the same time, the opening section 22 also has two opposing edge parts. Here, the two side edges of the opening section 22 are defined as the first edge 221 and the second edge 222 that are arranged opposite to each other. The first edge 221 is provided with a hook part 3. Usually, the hook part 3 is integrally connected with the sheet body 1 to obtain good connection stability. On this basis, the hook part 3 extends into the opening section 22 so that the inner side of the hook part 3 is arranged opposite to one end of the filter section 21. The hook part 3 can play the role of preventing the yarn from falling out of the filter groove 2.
[0038] It is understandable that the second edge 222 is spaced apart from the hook part 3 to form an assembly gap that communicates with the filter section 21. The yarn can be installed and removed from the sheet 1 through this assembly gap, so that the yarn can be replaced normally.
[0039] Based on the above solution, this embodiment provides a hook 3 at the opening section 22 of the filter tank 2, and sets the hook 3 opposite to the filter section 21 so that the yarn is blocked by the hook 3 when it jumps or deviates, thereby making it difficult for the yarn to loosen from the filter sheet and ensuring that the filtration operation is carried out smoothly.
[0040] Continue to refer to Figure 2For ease of description, the side of the hook portion 3 closest to the edge of the sheet 1 is defined as the outer side, and the side of the hook portion 3 away from the edge of the sheet 1 is defined as the inner side. To further prevent the yarn from falling out of the filter groove 2, a positioning notch 31 is recessed on the inner side of the hook portion 3. Specifically, in this configuration, the opening of the positioning notch 31 is positioned opposite to the filter section 21. When the yarn attempts to detach from the filter section 21, it will first be obstructed by the hook portion 3, and then the yarn will fall into the positioning notch 31. At this point, the yarn is further restricted, making it even more difficult for the yarn to detach from the filter section 21, thus further optimizing and improving the anti-detachment effect of the filter sheet.
[0041] Reference Figure 2 To further prevent the yarn from easily coming loose from the opening section 22, in this embodiment, the second edge 222 is flat in a portion of the area near the filter section 21, and the second edge 222 is inclined toward the side away from the hook part 3.
[0042] With the above structural arrangement, an inclined assembly gap can be formed between the second edge 222 and the hook part 3, thereby making the opening section 22 form a curved structural profile, making it more difficult for the yarn to come off from the opening section 22.
[0043] Optionally, an angle α is formed between the second edge 222 and the filter section 21, where α ranges from 20° to 40°. When α is less than 20°, the curvature of the opening section 22 may be too small, resulting in insufficient anti-loosening effect of the yarn. Conversely, when α is greater than 40°, the curvature of the opening section 22 may be too large, making yarn replacement difficult and inconvenient. Therefore, in this embodiment, the range of α is limited to 20° to 40°, ensuring stable anti-loosening function of the filter yarn without affecting yarn replacement operations.
[0044] For example, the specific value of α can be 20°, 30° or 40°. There is no limitation on the specific value of α. No matter what the specific value of α is, as long as it falls within the above range, it should be included in the scope of interpretation of this application.
[0045] Reference Figure 2In practical applications, since the yarn needs to be replaced regularly, the opening section 22 of the filter groove 2 forms a curved structural profile under the action of the hook part 3. This profile may make it difficult for the yarn to be assembled from the outside into the filter section 21 of the filter groove 2. Based on this, the hook part 3 in this embodiment is also provided with a first arc section 32 in the shape of an flared opening. At this time, under the guidance of the first arc section 32, the yarn is tightened on the outside of the sheet 1, and the first arc section 32 guides the yarn to move, so that the yarn slides into the filter section 21 by itself, thus optimizing and improving the convenience of yarn replacement.
[0046] Furthermore, the second edge 222 near the edge of the sheet 1 is provided with a second arc segment 33 in the shape of an opening. At this time, the second arc segment 33 can also guide the yarn. By tightening the yarn, the yarn slides into the filter section 21 by itself, and the convenience of yarn replacement is optimized and improved.
[0047] It should be added that the first arc segment 32 and the second arc segment 33 in this embodiment are arranged opposite to each other. This arrangement forms a trumpet-shaped structure. Therefore, whether the yarn is on the left or right side of the outer edge of the sheet 1, it can be smoothly slid into the filter section 21, and the ease of use is comprehensively improved.
[0048] In addition, looking back Figure 1 The filter tank 2 consists of multiple sets, spaced circumferentially along the sheet body 1. By using multiple sets of filter tanks 2, the yarn can be switched to different filter tanks 2 for filtration. In one embodiment, the gap size of the filter section 21 in different filter tanks 2 can be the same. In this case, multiple filter tanks 2 can avoid the impact of wear on filtration accuracy, greatly extending the service life of the filter sheet. In another embodiment, the gap size of the filter section 21 in different filter tanks 2 can also be different. In this case, filter tanks 2 with different gap sizes can provide different filtration accuracies for different yarn types, optimizing and improving the versatility of the filter sheet.
[0049] Optionally, when the gap size of the filter section 21 in different filter tanks 2 is different, the gap size of the filter section 21 is 0.25mm, 0.4mm, 0.6mm or 0.8mm. The gap size of the filter section 21 can be adjusted according to actual needs, and no specific limitation is made here. In this embodiment, there are four filter tanks 2, and the gap sizes of the filter section 21 in the four filter tanks 2 are 0.25mm, 0.4mm, 0.6mm and 0.8mm respectively. This can achieve four filtration precision functions to meet the filtration needs of various yarn types.
[0050] Furthermore, the sheet body 1 is provided with through holes 4 extending through both sides. On the one hand, the through holes 4 can reduce the overall weight of the sheet body 1, making the structure lighter and thinner; on the other hand, the through holes 4 can also optimize the heat dissipation effect of the sheet body 1 and improve the heat dissipation efficiency. Moreover, by setting the through holes 4, the structural strength of the sheet body 1 can also be improved, and the service life of the filter yarn sheet can be extended.
[0051] Example 2:
[0052] Based on Embodiment 1, features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here. This utility model provides a yarn feeder, including the anti-yarn escape filter sheet in Embodiment 1, and also includes a yarn feeder body. The anti-yarn escape filter sheet is disposed on the yarn feeder body, thus obtaining a yarn feeder that can effectively prevent yarn from loosening.
[0053] 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.
