Description

Technical Field

[0001] This utility model relates to the field of spinning technology, and in particular to a filament separating mechanism for spinning equipment. Background Technology

[0002] With the advancement and development of textile technology, the requirements for the spinning quality of spinning machines are becoming increasingly stringent. Therefore, existing equipment also needs to be reformed and innovated to keep pace with the times. Among them, the filament separating device plays a major role in separating filaments and is an indispensable component of the spinning machine. The filament separating device on the existing spinning machine generally uses ceramic components such as filament separating combs, guide hooks, ceramic rods, and ceramic wheels to complete the filament separating.

[0003] However, the friction between the filaments and the ceramic parts is sliding friction, which is relatively high and can easily affect the quality of the final filaments produced. At the same time, the ceramic parts are also very prone to wear, requiring frequent replacements during long production periods, which greatly affects production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a filament splitting mechanism for spinning equipment, which has low friction with the filament bundle, long service life, and greatly improves the production quality of the filament bundle.

[0005] This utility model is achieved through the following technical solution:

[0006] A filament separating mechanism for a spinning equipment, comprising:

[0007] A wheel axle, which is fixedly mounted on the spinning equipment;

[0008] Multiple filament splitting wheels are rotatably mounted on the axle, and each filament splitting wheel is arranged in a one-to-one correspondence with multiple filament bundles. Each filament splitting wheel can rotate independently, and grooves are formed on the filament splitting wheel to guide the corresponding filament bundle.

[0009] Furthermore, the plurality of the splitting wheels are arranged at uniform intervals along the axial direction of the wheel shaft.

[0010] Furthermore, the multiple splitting wheels are arranged coaxially.

[0011] Furthermore, there is a gap between two adjacent filament splitting wheels, and a baffle is provided on the radially outer side of the gap, the baffle being configured to prevent the filament bundle from entering the gap.

[0012] Furthermore, the baffle is integrally formed on at least one of the wire-splitting wheels on both sides of the gap.

[0013] Furthermore, the baffle is formed with rounded corners, which are configured to avoid scratching the filament bundle.

[0014] Furthermore, the groove has a V-shaped opening and an arc portion, which is located at the corner of the V-shaped opening.

[0015] Furthermore, the wire splitting wheel is made of aluminum alloy and has a ceramic coating on its surface.

[0016] Furthermore, the thickness of the ceramic coating is between 0.1 and 0.2 mm.

[0017] Furthermore, the filament separating mechanism for the spinning equipment also includes multiple bearings, which are sleeved on the axle and correspond one-to-one with the multiple filament separating wheels.

[0018] Compared with existing technologies, the advantages of this utility model are:

[0019] 1. By setting multiple rotatable wire separating wheels, the original sliding friction between the wire bundle and the wire separating mechanism is changed to rolling friction, which greatly reduces the friction between the wire separating wheel and the wire bundle passing through, thereby reducing the wear of the wire bundle and the wire separating mechanism, and greatly improving the service life of the wire separating mechanism and the quality of the produced wire bundle.

[0020] 2. By setting multiple filament splitting wheels to be independently rotatable, the tension of the filament bundle passing through each filament splitting wheel can be adjusted independently, which solves the problem of uneven tension on each filament bundle during the winding process and greatly improves the quality of the filament bundle.

[0021] 3. Multiple filament splitting wheels are nested in sequence, forming baffles on the filament splitting wheels to block the gaps between adjacent filament splitting wheels, thereby preventing filament bundles from entering the gaps and affecting production quality and efficiency.

In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0028] like Figure 1 As shown in the figure, an embodiment of this utility model provides a filament separating mechanism for a spinning equipment. Its main function is to separate filaments, specifically guiding multiple filament bundles 9 to separate them. Traditional spinning equipment typically uses ceramic components for filament separation. The filament bundles 9 and the ceramic components experience rolling friction, resulting in high frictional force, low quality of the produced filament bundles 9, and severe wear of the ceramic components, requiring frequent replacement. The filament separating mechanism provided in this application uses rolling friction with the filament bundles 9, thereby reducing wear between the filament bundles 9 and the separating mechanism, significantly improving the service life of the separating mechanism and the quality of the produced filament bundles 9. The following description is based on specific embodiments.

[0029] The filament separating mechanism mainly includes a shaft 1 and multiple separating wheels. The shaft 1 is fixedly mounted on the spinning equipment, serving a supporting function. Multiple separating wheels are rotatably mounted on the shaft 1, and each separating wheel corresponds to one of the filament bundles 9. Grooves 20 are formed on the separating wheels to guide the corresponding filament bundles 9. The rotatable separating wheels cause the separating wheels to rotate as the filament bundles 9 pass through them, thus changing the original sliding friction between the filament bundles 9 and the ceramic component to rolling friction. This significantly reduces the friction between the separating wheels and the passing filament bundles 9, thereby reducing wear on the filament bundles 9 and the separating mechanism, greatly improving the service life of the separating mechanism and the quality of the produced filament bundles 9.

[0030] Optionally, a fixing plate 10 is threadedly connected to the end of the axle 1 away from the splitting wheel, so as to facilitate installation on the spinning machine. At the same time, a fixing nut 11 is also threaded in the opposite direction. The threads of the fixing nut 11 and the fixing plate 10 are opposite, so that the fixing nut 11 can further lock the fixing plate 10 and prevent the axle 1 from shaking.

[0031] In this embodiment, the end of the axle 1 with the thread-dividing wheel is hollow to further reduce the overall weight, avoid greater force on the threaded connection, and thus improve service life.

[0032] Preferably, the wire separating mechanism further includes multiple bearings 14. The multiple bearings 14 are arranged one-to-one with the multiple wire separating wheels and are sleeved on the wheel shaft 1, forming a structure in which the wire separating wheels are sleeved on the bearings 14 and the bearings 14 are sleeved on the wheel shaft 1, thereby reducing the resistance encountered by the wire separating wheels when they rotate, so as to avoid the situation where the wire separating wheels do not rotate when the wire bundle 9 passes by.

[0033] To prevent multiple bearings 14 from sliding axially, multiple first retaining rings 12 are also fitted on the axle 1, with the first retaining rings 12 positioned between two adjacent bearings 14. Simultaneously, a second retaining ring 13 is embedded in the wire-dividing wheel to prevent the wire-dividing wheel from disengaging from the bearings 14.

[0034] At the same time, this setup allows each yarn splitter to rotate independently without affecting each other, and the yarn bundle speed can be inconsistent during winding. The winding tension is easier to control evenly, and the yarn cake is easier to form, thereby greatly improving production quality.

[0035] For details, please refer to Figure 2 and Figure 3 The groove 20 has a V-shaped opening and an arc portion 200, which is located at the corner of the V-shaped opening. When the filament bundle 9 passes through, it can move along the inclined sidewall of the groove 20 to the arc portion 200 to avoid scratching the filament bundle 9.

[0036] In addition, multiple filament separating wheels are evenly spaced along the axial direction of the wheel shaft 1, so that the distance between each groove 20 is equal, thereby ensuring that the spacing between each filament bundle 9 is equal, so as to ensure the quality of filament bundle 9 separation and facilitate subsequent production.

[0037] Meanwhile, multiple filament splitting wheels are coaxially arranged, and all are coaxial with wheel shaft 1, to ensure that the distance from each filament bundle 9 to the next device is equal, thereby making the tension on each filament bundle 9 equal, thus improving production quality.

[0038] Furthermore, there is a gap 8 between two adjacent splitting wheels. To prevent the filament bundle 9 from entering the gap 8 in case of abnormal conditions such as filament entanglement during spinning production, a baffle 25 is also provided on the radial outer side of the gap 8. During the production process, the baffle 25 can obstruct the movement of the filament bundle 9, causing it to move to one of the upper and lower grooves 20, thereby preventing the filament bundle 9 from entering the gap 8 and affecting the production quality of the filament bundle 9.

[0039] Optionally, the baffle 25 is integrally formed on at least one of the wire-separating wheels on both sides of the gap 8. In this embodiment, the wire-separating wheel includes a first part 21, a second part 22, and a groove part 23. The groove 20 is formed on the groove part 23. The second height h2 of the second part 22 in the radial direction is less than the height h1 of the first part 21. The baffle 25 is formed on the first part 21 and covers the second part 22 of the next wire-separating wheel in the radial direction, thereby forming a nested structure of multiple wire-separating wheels, making the structure compact in the axial direction. This arrangement allows the wire bundle 9 to be blocked by the baffle 25 when passing through it, thus sliding into one of the two adjacent grooves 20, preventing the wire bundle 9 from getting stuck in the gap 8 and being difficult to clean. At the same time, the baffle 25 also has a rounded corner 250 to avoid scratching the wire bundle 9.

[0040] In a preferred embodiment, the plurality of wire-separating wheels includes a first wire-separating wheel 3, a third wire-separating wheel 5, and a plurality of second wire-separating wheels 4 disposed between the first wire-separating wheel 3 and the third wire-separating wheel 5. The second wire-separating wheels 4, as described above, include a first part 21, a second part 22, a groove part 23, and a baffle 25, and the second height h2 is less than the height h1 of the first part 21. Since the third wire-separating wheel 5 is located at the bottom, it does not need to be nested with another wire-separating wheel; therefore, the third wire-separating wheel 5 does not have a baffle 25, thereby further reducing the axial installation space of the wire-separating mechanism. Simultaneously, the first part 21 of the first wire-separating wheel 3 is extended radially to improve aesthetics.

[0041] Preferably, the wire separating wheel is made of aluminum alloy, which has a robust structure, can be used for a long time, and does not require frequent replacement of wire separating parts. Furthermore, the surface of the wire separating wheel is coated with a ceramic layer to further reduce friction. The thickness of the ceramic coating is between 0.1 and 0.2 mm, preferably 0.15 mm.

[0042] Reference Figure 4 The filament splitting mechanism provided in this application can be applied in multiple places on the spinning machine frame 6 to split and guide filaments. Arrow X in the figure indicates the direction of the filament bundle.

[0043] This invention, by setting multiple rotatable wire separating wheels, changes the original sliding friction between the wire bundle 9 and the wire separating mechanism to rolling friction, greatly reducing the friction between the wire separating wheels and the passing wire bundle 9. This reduces wear on both the wire bundle 9 and the wire separating mechanism, significantly improving the service life of the wire separating mechanism and the quality of the produced wire bundle 9. Simultaneously, by setting multiple wire separating wheels to rotate independently, the tension of the wire bundle 9 passing through each wire separating wheel can be adjusted independently, solving the problem of uneven tension on each wire bundle 9 during winding and greatly improving the quality of the wire bundle 9. Furthermore, the multiple wire separating wheels are nested sequentially, with baffles 25 forming on the wire separating wheels to block the gaps 8 between adjacent wire separating wheels, thereby preventing the wire bundle 9 from entering the gaps 8 and affecting production quality and efficiency.

[0044] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
