[0002] Filter yarn device is a device for cleaning yarn itself during cloth forming process, such as in the process of cotton fiber spinning into yarn, there will be inevitably neps, hairiness and other impurities in the fiber, the above defects will cause the cloth to appear cross grain, pilling and other phenomena, and even affect the luster effect, sizing effect and dyeing and printing effect of the cloth, thereby affecting the forming quality of the cloth; in this case, the yarn storage device of the loom usually has a filter yarn function to remove neps, hairiness and other impurities to prevent them from entering the machine with the yarn and then entering the cloth.

[0003] A filter yarn device of a yarn storage and feeding device is disclosed in the utility model patent with the patent announcement No. CN2357019Y, which is arranged between the yarn inlet guide eye and the presser on the yarn inlet side of the yarn feeding device; the filter yarn device includes a plate body, which is punched from a metal plate, the plate body has a fixed hole in the center, and the plate body has a polygonal structure with a filter yarn groove around the periphery, the filter yarn groove extends into the interior of the plate body, and the filter yarn groove clamps the yarn without slipping; based on the above structure, during spinning, the yarn first moves from the yarn inlet guide eye to the filter yarn groove, the size of the filter yarn groove is relatively narrow, and the plate body can scrape off impurities during the process of the yarn passing through the filter yarn groove, thereby preventing the impurities from entering the loom and the cloth with the yarn, and realizing the filter yarn effect.

[0004] However, the current filter yarn device still has many defects, such as in a loom, usually hundreds or even thousands of fibers need to be spun, because the demand for yarn is large, a large number of yarn storage devices are usually arranged accordingly, and each yarn storage device is correspondingly provided with a filter yarn device; however, because different products have different filtering precision requirements, in actual production process, in order to adapt to the change of products, the filtering precision needs to be adjusted; the specific adjustment process is as follows: first, the equipment needs to be stopped, then the yarn needs to be cut off, and the plate body in each filter yarn device needs to be adjusted one by one, and the minimum filter gap of the commonly used filter yarn device is 0.4mm, and the filter yarn device with a filter gap smaller than 0.4mm is usually not easy to achieve, if it is made by other means, the yarn needs to be cut off first, then the original filter yarn device is removed by a screwdriver tool to replace the plate body, because the yarn storage device is usually arranged at a machine table higher than 1.8 meters, it is not easy to operate, even the whole yarn storage device needs to be removed for plate body replacement, and finally the yarn storage device and the yarn are reinstalled; the above replacement steps are complex, and because the number of yarns is large, the replacement work has a huge workload, and there is a problem of inconvenience in quickly replacing and adjusting the filtering precision of the yarn, which greatly affects the production efficiency of the product.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] The following is in conjunction with the appendix Figures 1-8 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0052] Example 1:

[0053] Please refer to Figure 1 This utility model provides a yarn filtering device, including a yarn guide arm 1 for guiding yarn. The yarn guide arm 1 is typically vertically fixed on a yarn storage device (not shown in the figure). The top of the yarn guide arm 1 has a wire guide hole 101. The yarn passes through the wire guide hole 101 into the yarn storage device. During this process, the yarn passes through the filter groove of the plate (not shown in the figure), which filters the yarn to remove impurities such as knots and feathers.

[0054] Furthermore, referring to Figure 2 Some products need to pass through air ducts before filtering the yarn, so the yarn guide arm 1 has an air duct installation port 102; specifically, the air duct installation port 102 is a long strip structure, and the air duct installation port 102 is used for the installation of air ducts; at this time, by passing the yarn through the air duct and passing airflow into the air duct, impurities on the yarn are blown away.

[0055] Different fabric products require different yarn filtration precisions. Common yarn filtration precisions include 0.4mm, 0.5mm, 0.7mm, or 1mm. However, before a loom can produce different fabric products, it is usually necessary to switch the yarn filtration precision. This requires stopping the machine. If a filter disc (plate) with a different, less common filtration precision is needed, the yarn may even need to be cut and the entire yarn storage unit removed for replacement. This disrupts the production process. Furthermore, a single loom typically has hundreds of yarn storage units, and correspondingly, the number of filter devices that need adjustment is also numerous. Moreover, the yarn storage units are usually located at a height of over 1.8 meters, making replacement work extensive and difficult. Therefore, there is a problem with the inconvenience of adjusting the filtration precision.

[0056] Based on this, refer to Figures 1-3The filter device disclosed in this embodiment includes, in addition to the yarn guide arm 1, a quick-release seat 2, a limiting element 3, a magnetic suction element 4, and a filter element 5. The quick-release seat 2 in this embodiment has a block-shaped structure. The limiting element 3 is disposed on one side of the quick-release seat 2 and is inserted into the duct installation port 102. The quick-release seat 2 is movably engaged with the yarn guide arm 1 via the limiting element 3. When the limiting element 3 is inserted into the duct installation port 102, the quick-release seat 2 is positioned on the yarn guide arm 1. Furthermore, by removing the limiting element 3 from the duct installation port 102, the quick-release seat 2 can be disassembled, making operation convenient.

[0057] It should be explained that, for ease of description, the following description is based on the placement of the quick-release bracket 2 in the installed state, at which point the quick-release bracket 2 has specific orientations such as bottom, side, and top.

[0058] Meanwhile, the magnetic suction element 4 is disposed on the quick-release base 2. It is understood that the magnetic suction element 4 can be a neodymium iron boron magnet, and the yarn guide arm 1 is made of metal. In this embodiment, the quick-release base 2 has a recessed receiving groove on the side opposite to the limiting element 3, and the magnetic suction element 4 is disposed in the receiving groove and fixed on the quick-release base 2. When the limiting element 3 engages with the yarn guide arm 1, the magnetic suction element 4 attracts to the yarn guide arm 1, thereby magnetically fixing the quick-release base 2 to the yarn guide arm 1, thus achieving a fixed installation of the quick-release base 2.

[0059] In addition, the filter element 5 is disposed on the quick-release seat 2. Specifically, the filter element 5 extends toward the side opposite to the limiting element 3, and the extended part of the filter element 5 has a filter gap 6 for the yarn to pass through. The size of the filter gap 6 is different from the size of the filter yarn groove on the original plate, and is usually smaller than the filter size of the plate filter yarn groove in order to obtain higher filtration accuracy.

[0060] Based on the above technical solution, when it is necessary to change the filtration accuracy of the yarn, the limiting element 3 can be directly inserted into the air duct installation port 102 without stopping the machine, and the limiting element 3 can be snapped into the air duct installation port 102, thereby positioning the quick-release seat 2. On this basis, the quick-release seat 2 is now tightly attached to the surface of the yarn guide arm 1, and the magnetic suction 4 presses the quick-release seat 2 onto the yarn guide arm 1 through magnetic attraction. The limiting element 3 is not easy to loosen from the air duct installation port 102, and the quick-release seat 2 is fixedly installed. Then, the filtration accuracy can be adjusted simply by moving the yarn into the filter gap 6 of the limiting element 3.

[0061] Correspondingly, when the filtration accuracy needs to be restored, the quick-release seat 2 can be directly removed from the yarn guide arm 1. The above process is quick and convenient, and can meet the needs of quick adjustment of large batches of yarn in the loom. Moreover, the adjustment process does not require stopping the machine or cutting the yarn, and does not affect the continued production, thus greatly optimizing and improving production efficiency.

[0062] Reference Figure 3 and Figure 4 To facilitate the quick-release seat 2 to be quickly assembled and positioned onto the yarn guide arm 1, the limiting element 3 in this embodiment includes a snap-fit ​​seat 31 and a snap-fit ​​strip 32. The snap-fit ​​seat 31 is connected to the quick-release seat 2, and typically, the snap-fit ​​seat 31 and the quick-release seat 2 are integrally connected to ensure good connection stability. Furthermore, the snap-fit ​​seat 31 in this embodiment has a long strip structure, thus adapting to the contour of the duct installation port 102. The length of the snap-fit ​​seat 31 is less than the opening length of the duct installation port 102, allowing the snap-fit ​​seat 31 to be adjusted and displaced along the length of the duct installation port 102 for easy snap-fit ​​installation.

[0063] Furthermore, the locking strip 32 is connected to the side of the locking seat 31 away from the quick-release seat 2. Typically, the locking strip 32 and the locking seat 31 are integrally connected to ensure good structural strength of the locking element. Simultaneously, the length of the locking strip 32 is set to be greater than the opening length of the duct mounting port 102. At this point, both ends of the locking strip 32 extend to opposite sides of the locking seat 31. It can be understood that the opposite sides referred to here are opposite sides of the locking seat 31 in the length direction. Based on this, a notch 33 is formed between the locking strip 32 and the locking seat 31, and there are two notches 33. The notches 33 can movably engage with the edge of the duct mounting port 102, thereby allowing the limiting element 3 to be locked and positioned onto the yarn guide arm 1.

[0064] Based on the above structure, when the limiting element 3 is snapped into the duct installation port 102, one side of the limiting element 3 can be tilted and inserted into the duct installation port 102 first, so that one of the notches 33 is embedded in the edge of the duct installation port 102. At this time, it is equivalent to avoiding the other side of the limiting element 3. Then, the limiting element 3 is straightened so that the other side of the limiting element 3 is inserted into the duct installation port 102. Then, the limiting element 3 is slid along its length in the duct installation port 102 until both ends of the locking strip 32 abut against the yarn guide arm 1 to achieve the snapping and positioning effect. Then, under the reinforcement of the magnetic suction part 4, the quick release seat 2 is fixed.

[0065] Furthermore, the equipment usually vibrates during operation. If the quick-release seat 2 is loose, the filter element 5 will swing. Since the filter element 5 has a high filtration accuracy, the yarn usually moves at high speed during the filtration of impurities. When the filter element 5 swings, the yarn is prone to wear or even breakage. Based on this, under the magnetic attraction, the contact surface 21 and the surface of the yarn guide arm 1 are tightly attached to each other, thereby increasing the connection stability between the quick-release seat 2 and the yarn guide arm 1, making the quick-release seat 2 and the filter element 5 less prone to loosening and the structure more robust.

[0066] Understandably, based on the above structural setup, under the bonding action of the bonding plane 21, and under the positioning action of the limiting element 3 and the attraction action of the magnetic suction part 4, not only is the quick-release seat 2 and the filter element 5 quickly disassembled and assembled, but the stability of the filter yarn action is also improved, avoiding damage or breakage of the yarn, and ensuring the smoothness and stability of the filtration action.

[0067] Furthermore, as the production quality requirements of products continue to improve, the requirements for the filtration accuracy of yarn also continue to improve. In this embodiment, the spacing of the filter gap 6 is less than or equal to 0.2mm, thereby improving the filtration accuracy and enabling the removal of more impurities. For example, the size of the filter gap 6 can be customized to 0.1mm, 0.15mm or 0.2mm, etc., and no specific limitation is made here.

[0068] It needs to be explained that, based on the aforementioned filter gap 6 configuration, traditional filter yarn structures struggle to achieve high-precision filtration below 0.2mm. This is because the filter plates are typically produced using two processes. One is stamping, which involves using a stamping die to cut into the plate material. However, gaps smaller than 0.2mm cannot be achieved through stamping. Firstly, the punch is too thin and prone to breakage, and the cutting area is too narrow, resulting in a high defect rate. Secondly, the edges of the gaps formed by stamping have burrs, which increase wear on the yarn, easily causing breakage and hindering the desired filtration effect.

[0069] Another process is the integral ceramic molding process, which uses ceramic sintering to obtain a sheet structure with gaps. However, the ceramic molding process also has limitations. Specifically, the resulting sheet structure is too brittle during the ceramic sintering process. When the gap is less than 0.2mm, uneven heating or cooling of the sheet structure can lead to deformation or even cracking of the component. Therefore, the overall yield of the sheet obtained by the ceramic molding process is low. In addition, the ceramic sintering process is complicated, resulting in high production costs, which also cannot meet the requirements.

[0070] Based on this, refer to Figure 4 and Figure 5 To achieve filtration accuracy below 0.2mm, this solution includes a first filter element 51 and a second filter element 52. Both the first filter element 51 and the second filter element 52 are mounted on the quick-release base 2, specifically at the bottom of the quick-release base 2 and adjacent to each other. The first filter element 51 has a first edge, and the second filter element 52 has a second edge. The first and second edges are opposite to each other and parallel to each other. Based on this structure, a filter gap 6 can be formed between the first and second edges.

[0071] In the above scheme, the filter element 5 adopts a split filter structure. By setting two independent first filter plates 51 and second filter plates 52, on the one hand, the two components can be stamped separately, which greatly reduces the processing difficulty, makes the yield rate higher, and further reduces the manufacturing cost; on the other hand, by controlling the distance between the two, a narrower filter gap 6 can be obtained conveniently and accurately, which makes it possible to set the filter gap 6 below 0.2mm.

[0072] In addition, by setting two first filter plates 51 and a second filter plate 52, the first and second edges can be polished. Specifically, the first and second edges can be polished using sandpaper or a grinding wheel. At this time, smooth polished surfaces are formed at the relative positions of the first and second edges, which can overcome the burr problem in traditional stamping processes. The polished surfaces can avoid abrading the yarn, thus optimizing the filtration effect.

[0073] Here, compared with conventional stamping processes, the filter element 5 of this solution achieves a filter gap 6 of less than 0.2mm by adopting a split structure. At the same time, it can also avoid the problem of burrs in the filter gap 6 under conventional stamping conditions. In addition, compared with ceramic forming processes, the split filter element 5 of this embodiment can also reduce manufacturing difficulty, thereby improving forming yield and reducing manufacturing costs, and effectively solving the problems of low yield and high cost of sintering processes.

[0074] It can also be understood that this embodiment provides a filter element 5 that can meet the high-precision filtration requirements below 0.2mm, and overcome the problems of burrs in the filter gap 6 and excessive manufacturing costs. Furthermore, the filter element 5 in this solution can also be integrated into the quick-release seat 2, ultimately resulting in a filter yarn device that can quickly adjust the filtration accuracy without stopping the machine and reduce manufacturing and usage costs.

[0075] Furthermore, continue to refer to Figure 4 and Figure 5 One end of the first filter 51 is connected to the quick-release seat 2, and the other end of the first filter 51 is away from the quick-release seat 2; correspondingly, one end of the second filter 52 is also connected to the quick-release seat 2, and the other end of the second filter 52 is away from the quick-release seat 2.

[0076] At this time, a hook portion 511 is provided on the end of the first filter 51 away from the quick-release seat 2. The hook portion 511 passes around the end of the second filter 52 away from the quick-release seat 2 and extends to the side of the second filter 52 away from the first filter 51. An anti-detachment gap 7 is formed between the hook portion 511 and the second filter 52 and is connected to the filter gap 6. The anti-detachment gap 7 has a barbed structure.

[0077] By adopting the above structure, before the yarn is moved to the filter gap 6, it is first moved to the anti-loosening gap 7. The barbed structure of the anti-loosening gap 7 can prevent the yarn from loosening from the filter gap 6, thus optimizing and improving the stability of the filtration action.

[0078] Reference Figure 4 In this embodiment, the first filter element 51 and the second filter element 52 are respectively fixedly mounted on the quick-release base 2 by threaded fasteners 8. Specifically, a threaded hole is provided at the bottom of the quick-release base 2, and mounting holes are provided on the first filter element 51 and the second filter element 52 respectively. The threaded fasteners 8 are screws. By passing the screws through the mounting holes and threading them into the threaded holes, the first filter element 51 and the second filter element 52 are fixedly mounted. The assembly process is simple and convenient.

[0079] Furthermore, to improve the overall accuracy of the filter gap 6, a positioning block 9 is provided on the quick-release base 2. In this embodiment, the positioning block 9 is located at the bottom of the quick-release base 2 and is rectangular in shape, with two parallel positioning sides. At the same time, the positioning block 9 is positioned between the first filter sheet 51 and the second filter sheet 52, and the first filter sheet 51 and the second filter sheet 52 are respectively provided with a latch 10 that engages with the positioning block 9. The opening contour of the latch 10 matches the outer contour of the positioning block 9, and the inner edge of the latch 10 abuts against the positioning side.

[0080] Based on the above structural configuration, the positioning block 9 positions the spacing between the first filter element 51 and the second filter element 52, thereby optimizing and improving the dimensional accuracy of the filter gap 6.

[0081] Furthermore, the positioning blocks 9 and the locking slots 10 that cooperate with each other can be set in multiple groups, such as two, three or four groups. By setting multiple groups of positioning blocks 9 and locking slots 10, the positional accuracy of the first filter 51 and the second filter 52 can be further improved. In this embodiment, the number of positioning blocks 9 and locking slots 10 is set to two groups as an example. The specific number of positioning blocks 9 and locking slots 10 is not limited here.

[0082] This embodiment has the following effects:

[0083] 1. By using a plug-in and snap-fit ​​method, the quick-release base 2 and the filter element 5 can be quickly installed and removed from the yarn guide arm 1, allowing for efficient and convenient adjustment of the yarn filtration accuracy.

[0084] 2. By using the existing air duct installation port 102 on the yarn guide arm 1 as the installation hole of the quick-release seat 2, the versatility of the yarn filter device can be effectively improved. There is no need to add a complex installation structure, and it can be used with most mainstream yarn storage devices, thus achieving cost reduction and efficiency improvement.

[0085] 3. The filter element 5 adopts a split first filter sheet 51 and a second filter sheet 52, which can realize the free combination of filter gaps 6 and can also grind the edge of the filter gaps 6, thus significantly improving the filtration accuracy and filtration effect, and can well meet the filter yarn accuracy requirements of different products.

[0086] Example 2:

[0087] Based on Embodiment 1, features not explained in this embodiment will be explained using the methods described in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is that the filter element 5 is set in a different way.

[0088] Reference Figure 6 and Figure 7 To further improve the ease of installation of the filter element 5, the quick-release base 2 is provided with a first slot 11. Specifically, the first slot 11 is recessed from the outside to the inside on the side of the quick-release base 2 away from the yarn guide arm 1, and the first slot 11 also has an opening at the bottom surface of the quick-release base 2; at the same time, the first filter sheet 51 has a first elastic buckle 12 that is movably engaged with the first slot 11. The first elastic buckle 12 has a spring sheet structure and is usually obtained by punching and bending the first filter sheet 51.

[0089] At this time, by inserting the first filter element 51 into the opening on one side of the first slot 11 until the first elastic buckle 12 is engaged with the opening on the bottom surface of the first slot 11 at the quick-release base 2, the first filter element 51 is fixedly installed on the quick-release base 2. When it is necessary to replace the first filter element 51, simply press the first elastic buckle 12 to loosen it from the first slot 11, and the first filter element 51 can be pulled out of the quick-release base 2. The operation is simple and quick.

[0090] Correspondingly, the quick-release base 2 is provided with a second slot 13, which is set in the same way as the first slot 11. The second filter 52 has a second elastic buckle 14 that is movably engaged with the second slot 13. The setting principle of the second filter 52 is the same as that of the first filter 51, and will not be described in detail here.

[0091] It should be explained that, in order to ensure that the filter gap 6 has high structural accuracy when using the first slot 11 and the second slot 13 for installation, on the one hand, the spacing accuracy of the filter gap 6 can be controlled by controlling the distance between the first slot 11 and the second slot 13; on the other hand, the distance between the first edge and the second edge can also be controlled by controlling the external dimensions between the first filter sheet 51 and the second filter sheet 52. Both of these methods can ensure that the filter gap 6 maintains high structural accuracy.

[0092] In this embodiment, the filter element 5 is quickly installed and removed by using a flexible snap-fit ​​mechanism, which facilitates the periodic replacement of the filter element 5 and helps the filter yarn device maintain a high filtration accuracy.

[0093] Example 3:

[0094] 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 snap-fit ​​positioning method of the limiting element 3 is different.

[0095] Reference Figure 8 The limiting element 3 includes two parallel elastic hooks 34. The two elastic hooks 34 are parallel to each other and are set on the quick-release seat 2. Usually, the elastic hooks 34 are integrally connected with the quick-release seat 2 to obtain good connection stability. At the same time, the structural length of the elastic hooks 34 is adapted to the length of the air duct installation port 102. At this time, the elastic hooks 34 can be inserted into the air duct installation port 102 and movably locked with the yarn guide arm 1.

[0096] In this embodiment, the elastic hook 34 can quickly assemble the quick-release seat 2 onto the yarn guide arm 1, thus achieving the same convenient assembly and disassembly function. It is understood that any structure that can quickly install the limiting element 3 onto the air duct installation port 102 can be used. No specific setting method will be limited here. Furthermore, regardless of the specific limiting element 3 used, it should be included in the interpretation scope of the limiting element 3 in this application.

[0097] 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.
