Abstract
Description
Technical Field
[0001] This application relates to the field of textile equipment, and more particularly to a filament separating device and an industrial filament stretching and winding device. Background Technology
[0002] In existing spinning equipment, it is necessary to adjust the yarn splitting. Typically, in industrial yarn stretching and winding equipment, this can be achieved by adjusting the splitting wheel or the splitting wheel bracket.
[0003] When adjusting the wire divider, first use a tool to hold the nut on one side of the wire divider in place, then use the same tool to slightly loosen the nut on the other side. After adjusting, reverse the process to tighten the wire divider. When adjusting the support, the tool needs to pass through the wire bundle adjustment screw.
[0004] It should be noted that the above description of the background technology is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background technology section of this application. Utility Model Content
[0005] The inventors discovered the following problems with the existing wire separating device: When adjusting the wire separating wheel, the nut on the opposite side must not be loosened too quickly, otherwise the wire separating wheel will be bounced away by the wire, resulting in wire tangling. Furthermore, both hands are occupied at this time, and if the tool is used to move the wire separating wheel, the position is difficult to control and the tool is prone to detaching from the nut; the bolt must be quickly pressed down by hand before adjustment. When adjusting the support, the tool will rub and shake the wire bundle, easily leading to wire tangling and fuzzing. In other words, the existing device makes online adjustment of the wire separating wheel difficult, prone to wire tangling or breakage. Additionally, the operating space is small, making operation inconvenient. Gaskets are placed between the wire separating wheel, support, and nut, which is not conducive to installation. After replacing the wire separating wheel, the wire path needs to be readjusted. During the adjustment process, the operator's arms are in the confined space of the insulation box for a long time, making them prone to burns and / or cuts.

[0031] The embodiments of this application will now be described with reference to the accompanying drawings.
[0032] First aspect of the embodiments
[0033] An embodiment of the first aspect of this application provides a wire splitting device.
[0034] Figure 1 This is a schematic diagram of a wire splitting device according to an embodiment of the first aspect of this application, showing a front view of the wire splitting device viewed from the right side; Figure 2 It is along Figure 1 A cross-sectional view of line A-A' shows a schematic diagram of the wire splitting device viewed from above.

[0035] like Figure 1 and Figure 2 As shown, the wire splitting device 1 may include a frame 10, a slider 20, a connecting rod 30, and a wire splitting wheel 40. The frame 10 forms a receiving cavity S1 that is recessed rearward in a first direction A1. The slider 20 is threadedly connected to a bolt BT that passes through the receiving cavity S1 in a second direction A2. The slider 20 is slidably received in the receiving cavity S1 in the second direction A2. The connecting rod 30 is movably fixedly connected to the frame 10 and the slider 20 in the first direction A1. That is, the connecting rod 30 can move relative to the frame 10 and the slider 20. When it moves to a certain position, the connecting rod 30 can be fixed together with the frame 10 and the slider 20, that is, no relative displacement occurs. The wire splitting wheel 40 is fixedly connected to the connecting rod 30.
[0036] According to the above embodiment, by providing a slider 20 that is threadedly connected to the receiving cavity S1 of the frame 10 through the bolt BT thread in the second direction A2, and a connecting rod 30 that is movably fixedly connected to the frame 10 and the slider 20, the movement of the wire separating wheel 40 in the first direction A1 and the second direction A2 can be easily realized, thereby facilitating online adjustment of the wire separating wheel 40, which is convenient, quick, and less likely to cause wire breakage.
[0037] In this embodiment, the slider 20 can be threadedly connected to the bolt BT using any feasible structural form to achieve sliding of the slider 20 in the second direction A2. The structure of the threaded connection between the slider 20 and the bolt BT will be illustrated below.
[0038] In the embodiments of this application, the connecting rod 30 can move relative to the frame 10 and the slider 20 in the first direction A1 through any feasible structural form, and can also be fixedly connected to both through any feasible structural form. Specific examples will be given below illustrating the specific structures by which the connecting rod 30 moves relative to and is fixed to the frame 10 and the slider 20.
[0039] In this embodiment, the wire splitter 40 can be fixedly connected to the connecting rod 30, for example, by screws.
[0040] In the embodiments of this application, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7As shown, the frame 10 may include: a base plate 101, a first vertical wall portion 102, a second vertical wall portion 103, a third vertical wall portion 104, and a top plate 105. The first vertical wall portion 102 extends upward from the left end of the base plate 101 into a plate shape; the second vertical wall portion 103 extends upward from the right end of the base plate 101 into a plate shape; the third vertical wall portion 104 extends upward from the rear end of the base plate 101 into a plate shape and is fixedly connected to the rear ends of the first vertical wall portion 102 and the second vertical wall portion 103 respectively in the second direction A2. That is, the left end of the third vertical wall portion 104 is fixedly connected to the first vertical wall portion 102, and the right end of the third vertical wall portion 104 is fixedly connected to the second vertical wall portion 103.
[0041] Thus, the receiving cavity S1 is formed by the bottom plate 101, the first vertical wall portion 102, the second vertical wall portion 103, the third vertical wall portion 104 and the top plate 105.
[0042] In the embodiments of this application, the fixed connection between the components of the frame 10 can be achieved by means of bonding or other methods, or the components can be integrally formed.
[0043] In the embodiments of this application, such as Figure 3 As shown, a hook HH can also be formed on the right side of the top plate 105. The specific location of the hook formation is not limited to that shown in the figure.
[0044] In the embodiments of this application, such as Figure 5 As shown, the first vertical wall portion 102 is provided with a first through hole H1 that penetrates its thickness in the second direction A2, and the second vertical wall portion 103 is provided with a second through hole H2 that penetrates its thickness in the second direction A2. The bolt BT passes through the first through hole H1 and the second through hole H2.
[0045] The left end of the bolt BT is provided with a nut N that is integral with the bolt BT, and the right surface F1 of the nut N abuts against the left surface F2 of the first vertical wall 102.
[0046] A shaft retaining ring SR is fixedly connected to the right end of the bolt BT, and the left surface F3 of the shaft retaining ring SR abuts against the right surface F4 of the second vertical wall 103.
[0047] Therefore, the nut N can prevent the bolt BT from shifting to the left, and the shaft retaining ring SR can prevent the bolt BT from shifting to the right. In other words, the bolt BT will only rotate in place and will not move left or right. Thus, when adjusting the threaded wheel, the nut N and the shaft retaining ring SR can limit the left and right movement of the bolt, eliminating the need for the operator to quickly press the bolt down by hand and then adjust it, thereby further achieving the purpose of convenient operation.
[0048] In the embodiments of this application, such as Figure 5As shown, the bolt BT in the first through hole H1 and the second through hole H2 is unthreaded, and the bolt BT connected to the shaft retaining ring SR is also unthreaded. In other words, the portion of the bolt BT in the through hole is unthreaded, and the bolt BT has a clearance fit with the through hole. This allows the bolt BT to rotate more smoothly without increasing resistance.
[0049] In the embodiments of this application, such as Figure 5 and Figure 6 As shown, a fastening nut FBT is provided on the right end of the bolt BT, which is movably threaded to the bolt. The fastening nut FBT has a groove G1 recessed to the right from its left surface. The depth D1 of the groove G1 in the second direction A2 is greater than the thickness D2 of the shaft retaining ring SR in the second direction A2. When the fastening nut FBT is in the tightened state ( Figure 5 When (as shown), the left side surface F5 of the fastening nut FBT abuts against the right side surface F4 of the second vertical wall portion 103, that is, when the fastening nut FBT is in the tightened state (as shown), Figure 5 As shown, the shaft retaining ring SR is accommodated in the groove G1, which facilitates the fastening nut FBT to lock the bolt BT.
[0050] Thus, when the fastening nut FBT is tightened, the bolt BT cannot rotate, meaning the slider 20 and connecting rod 30 cannot move in the second direction A2. When the fastening nut FBT is loosened, the bolt BT can rotate, meaning the slider 20 and connecting rod 30 can move in the second direction A2; for example, as... Figure 1 As shown, the bolt BT has a standard hexagonal shape at its axial position, which allows the bolt BT to be rotated using tools such as hexagonal sockets, enabling relatively accurate adjustment of minute dimensions.
[0051] In the embodiments of this application, such as Figure 4 and Figure 5 As shown, the slider 20 is provided with a third through hole H3 penetrating the slider 20 in the second direction A2, a fourth through hole H4 penetrating the slider 20 in the first direction A1, and a fifth through hole H5 penetrating the top of the slider 20 from the fourth through hole H4 upwards. The bolt BT is threadedly connected to the slider 20 through the third through hole H3. For example, the third through hole H3 of the slider 20 is provided with an internal thread that engages with the external thread of the bolt BT. In this way, when the bolt BT rotates, it can drive the slider 20 to move in the second direction.
[0052] like Figure 3 , Figure 4 , Figure 5 and Figure 7As shown, the third vertical wall 104 is provided with a sixth through hole H6 that penetrates its thickness in the first direction A1, and the top plate 105 is provided with a seventh through hole H7 that penetrates its thickness in the third direction A3. The seventh through hole H7 and the fifth through hole H5 are opposite each other in the third direction A3. The connecting rod 30 penetrates the fourth through hole H4 and the sixth through hole H6. The connecting rod 30 is movably and fixedly connected to the frame 10 and the slider 20 through the set screw JS that penetrates the seventh through hole H7 and the fifth through hole H5.
[0053] In this embodiment, the connecting rod portion 30 can be clearance-fitted with the fourth through hole H4 and the sixth through hole H6. When the set screw JS is tightened, the connecting rod portion 30 is immovable relative to the frame 10 and the slider 20. When the set screw JS is loosened, the connecting rod portion 30 can move relative to the frame 10 and the slider 20. Therefore, the connecting rod portion 30 equipped with the wire dividing wheel 40 is easy to assemble and disassemble from the frame 10. Simply loosen the set screw and remove or install the wire dividing wheel together with the connecting rod.
[0054] In the embodiments of this application, such as Figure 3 and Figure 7 As shown, the sixth through hole H6 and the seventh through hole H7 have a certain length in the second direction A2, that is, the inner diameter of the through hole. The inner diameter of the sixth through hole H6 and the inner diameter of the seventh through hole H7 are approximately the same, and this inner diameter is the range of movable distance of the slider 20 in the second direction.
[0055] In the embodiments of this application, such as Figure 2 As shown, the connecting rod portion 30 may include a wire-splitting wheel receiving portion 301 and a connecting fixing portion 302. Viewed from a third direction, the wire-splitting wheel receiving portion 301 is formed as a U-shaped portion capable of accommodating the wire-splitting wheel 40; the connecting fixing portion 302 extends rearward from the rear end of the wire-splitting wheel receiving portion 301 in a rod-like shape, and the connecting fixing portion 302 is integrally formed with the wire-splitting wheel receiving portion 301, such as... Figure 4 As shown, the connecting fixing part 302 passes through the fourth through hole H4 and the sixth through hole H6, and is movably and fixedly connected to the frame 10 and the slider 20 by the set screw JS.
[0056] In this way, the splitting wheel 40 can be easily installed and removed through the splitting wheel receiving part 301, and during the adjustment of the splitting wheel, there is no need to put your hands into the heat preservation box, avoiding burns and cuts and improving safety.
[0057] In this embodiment, a scale may also be provided on the connecting fixing part 302, so that the original thread path can be quickly restored when the connecting rod part 30 is disassembled and reinstalled.
[0058] In the embodiments of this application, the main structure of the wire splitting device 1 has been described above, but the wire splitting device 1 may also include other structures, as can be found in the prior art.
[0059] According to the embodiment of this application, the wire splitting device can easily realize the movement of the wire splitting wheel 40 in the first direction A1 and the second direction A2 by providing a slider 20 that is threadedly connected to the receiving cavity S1 of the frame 10 through the bolt BT thread in the second direction A2, and a connecting rod portion 30 that is movably fixedly connected to the frame 10 and the slider 20. This facilitates online adjustment of the wire splitting wheel 40, which is convenient, quick, and less likely to cause wire breakage.
