Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to an eight-spindle compact spinning device. Background Technology

[0002] Compared to compact spinning, yarn produced by drive ring spinning is more prone to fuzzing at the edges, and the loose fiber arrangement of the yarn affects its strength.

[0003] Purchasing compact spinning equipment directly is costly. A better approach is to convert ring spinning to compact spinning, reusing some core components and reducing upgrade costs. However, ring spinning rollers lack sufficient space for negative pressure tubes. Furthermore, some ring spinning systems use independently designed suction nozzles to absorb yarn fuzz; adding negative pressure tubes complicates adjusting the position and angle of these multiple suction nozzles.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an eight-spindle compact spinning device to facilitate the upgrading of traditional ring spinning to compact spinning.

[0006] The technical solution of this utility model is as follows: The eight-spindle compact spinning device includes: a roller seat, an extension sleeve connected to the roller seat, and a flute holder connected to the extension sleeve; a traction assembly is provided on the roller seat; a negative pressure tube is provided on the extension sleeve; a cotton suction flute is provided on the flute holder; wherein, a first slot is provided on the flute holder; plugs are respectively sealed at both ends of the cotton suction flute; the plugs are inserted into the first slot; along the axial direction of the negative pressure tube, the cotton suction flute has at least two suction ports facing the negative pressure tube; the negative pressure tube and the cotton suction flute each have interfaces for connecting to a negative pressure source.

[0007] A further technical solution is that the traction assembly includes a front roller, a middle roller, and a rear roller; a first slide, a second slide, and a third slot are provided on the roller seat; the first slide fixes the rear roller; the second slide fixes the middle roller; and the third slot fixes the front roller.

[0008] A further technical solution is that a fixing groove is formed on the roller seat along its length; a connecting hole is formed on the first slide to align with the fixing groove.

[0009] A further technical solution is that, along the length direction of the roller seat, the first slide block has a first groove on its surface near the roller seat; the roller seat is engaged in the first groove.

[0010] A further technical solution is that, along the length direction of the roller seat, a second slide groove is formed on the surface of the second slide near the roller seat; a slide rail is provided on the surface of the extension sleeve away from the roller seat; and the slide rail is engaged with the second slide groove.

[0011] A further technical solution is that a through hole is formed on the extension sleeve; a connecting hole is formed on the second slide to align with the through hole and the fixing groove.

[0012] A further technical solution is that, along the length of the cotton-absorbing tube, an overlapping portion extends from the plug; the overlapping portion is inserted into the first slot; perpendicular to the length of the cotton-absorbing tube, the cross-section of the overlapping portion is rectangular, and the cross-section of the first slot corresponds to the cross-sectional shape of the overlapping portion.

[0013] A further technical solution is to provide a bridge gear between the traction component and the negative pressure pipe.

[0014] A further technical solution is that the bridge gear includes a screw passing through the extension sleeve and a nut sleeved on the screw; the screw abuts against the end of the roller seat near the extension sleeve.

[0015] A further technical solution is that, perpendicular to the length direction of the roller seat, the extension sleeve is provided with a positioning pin and a threaded fastener.

[0016] The beneficial technical effects of this utility model are as follows: (1) In the eight-spindle compact spinning device of this utility model, an extension sleeve is added to the roller seat to facilitate the installation and fixing of the negative pressure pipe. At the same time, a flute bracket is set on the extension sleeve to fix the position of the cotton suction flute. The flute bracket has a first slot to engage the cotton suction flute, making the installation of the cotton suction flute convenient. By setting the extension sleeve and the cotton suction bracket on the conventional roller seat, the negative pressure pipe and the cotton suction flute can be fixed, so as to reuse the roller seat of ring spinning and reduce the cost of upgrading ring spinning to compact spinning. Moreover, multiple cotton suction ports are opened on the cotton suction flute. The position and angle of all cotton suction ports can be adjusted by adjusting the position and angle of the cotton suction flute individually, improving the efficiency of equipment modification.

[0027] Figure 1 A front view structural schematic diagram of an eight-spindle compact spinning apparatus according to an embodiment of the present disclosure is shown. Figure 2 A cross-sectional view at point A is shown of an eight-spindle compact spinning apparatus according to an embodiment of this disclosure. Please refer to... Figure 1 and Figure 2 The eight-spindle compact spinning device includes a roller seat 1, an extension sleeve 2 connecting the roller seat 1, and a flute holder 3 connecting the extension sleeve 2. A traction assembly is installed on the roller seat 1. The extension sleeve 2 facilitates the installation of a negative pressure tube 4. A suction flute 5 is installed on the flute holder 3. The flute holder 3 and the extension sleeve 2 can be integrated or separate. Separating the flute holder 3 and the extension sleeve 2 facilitates adjustment of the angle of the suction flute 5, ensuring the suction port accurately faces the suction position. A first slot 31 is provided on the flute holder 3. Plugs 51 are sealed at both ends of the suction flute 5. The plugs 51 engage with the first slot 31, connecting the suction flute 5 and the flute holder 3. The plugs 51 and the first slot 31 have an interference fit. This snap-fit ​​connection facilitates assembly and disassembly. Through the extension sleeve 2 and the flute holder 3, the roller seat 1 of the ring spinning machine can be reused. Along the axial direction of the negative pressure pipe 4, the suction pipe 5 has at least two suction ports facing the negative pressure pipe 4. Both the negative pressure pipe 4 and the suction pipe 5 have interfaces 41 connected to the negative pressure source. Adjusting the position and angle of the suction pipe 5 individually allows for adjustment of the position and angle of all suction ports, improving the efficiency of equipment modification.

[0028] Preferably, an overlapping portion 511 extends from the plug 51 along the length of the suction tube 5. The overlapping portion 511 engages with the first slot 31. Perpendicular to the length of the suction tube 5, the cross-section of the overlapping portion 511 is rectangular, and the cross-section of the first slot 31 corresponds to the cross-sectional shape of the overlapping portion 511. The rectangular overlapping portion 511 and the rectangular first slot 31 cooperate to fix the angle of the suction tube 5, ensuring that the suction port faces the negative pressure tube 4.

[0029] Figure 1 A front view structural schematic diagram of an eight-spindle compact spinning apparatus according to an embodiment of the present disclosure is shown. Figure 2 A cross-sectional view at point A is shown of an eight-spindle compact spinning apparatus according to an embodiment of the present disclosure. Figure 3A perspective view of the first slide in an eight-spindle compact spinning apparatus according to an embodiment of this disclosure is shown. Please refer to... Figure 1 , Figure 2 and Figure 3 The traction assembly includes a front roller 61, a middle roller 62, and a rear roller 63, which rotate at different speeds to refine and pull the yarn to the position of the negative pressure tube 4. The roller seat 1 is provided with a first slide 12, a second slide 13, and a third slot 11. The first slide 12 fixes the rear roller 63. The second slide 13 fixes the middle roller 62. The third slot 11 fixes the front roller 61. Specifically, bearings (not shown in the figure) can be fitted onto the rear roller 63, the middle roller 62, and the front roller 61. Slots (not marked in the figure) are respectively opened on the first slide 12 and the second slide 13. Each bearing and slot, as well as the bearing and the third slot 11, are interference-fitted. The rear roller 63, the middle roller 62, and the front roller 61 are rotatably connected to the roller seat 1 via bearings.

[0030] Preferably, a fixing groove 14 is formed on the roller seat 1 along its length. The fixing groove 14 can be a T-groove. A connecting hole 122 is formed on the first slide 12 to align with the fixing groove 14. A bolt (not shown in the figure) extends into the fixing groove 14 through the connecting hole 122 and is connected to a nut (not shown in the figure). The nut abuts against the T-groove opening of the fixing groove 14 to fix the first slide 12 on the roller seat 1.

[0031] More preferably, along the length of the roller seat 1, a first groove 121 is formed on the surface of the first slide block 12 near the roller seat 1. The roller seat 1 engages with the first groove 121. The first groove 121 restricts the positional relationship between the first slide block 12 and the roller seat 1, improving the stability of the connection between the first slide block 12 and the roller seat 1. At the same time, when adjusting the position of the first slide block 12 along the roller seat 1, the first groove 121 can serve as a guide.

[0032] Figure 4 A three-dimensional structural diagram of the elongated sleeve in a top view is shown in an eight-spindle compact spinning apparatus according to an embodiment of the present disclosure. Please refer to... Figure 1 , Figure 2 and Figure 4 Along the length of roller seat 1, a second groove (not shown in the figure) is formed on the surface of the second slide 13 near roller seat 1. An extension sleeve 2 extends from the surface of roller seat 1 with a slide rail 22. The slide rail 22 engages with the second groove. That is, roller seat 1, in conjunction with the second slide 13, clamps and fixes the position of the extension sleeve 2. Furthermore, the cooperation of the slide rail 22 and the second groove enhances the stability of the connection between the second slide 13 and the extension sleeve 2, while also allowing for quick positioning of the two components.

[0033] Preferably, the extension sleeve 2 has a through hole 221. The second slide 13 has a connecting hole 122 aligned with the through hole 221 and the fixing groove 14. The bolt extends into the fixing groove 14 along the connecting hole 122 and the through hole 221, and the part of the bolt extending into the fixing groove 14 is connected to the nut to fix the second slide 13 on the roller seat 1, while clamping and fixing the extension sleeve 2.

[0034] Figure 5 A perspective view of an eight-spindle compact spinning apparatus according to an embodiment of this disclosure is shown, with the negative pressure tube and tension bar omitted. Please refer to... Figure 1 , Figure 2 and Figure 5 A bridge gear 44 is provided between the traction assembly and the negative pressure tube 4. Specifically, a retainer 42 is sealed at both ends of the negative pressure tube 4. A second retainer 21 is provided on the extension sleeve 2 for the retainer 42 to be inserted, and the second retainer 21 and the retainer 42 are interference-fitted. A tension bar 43 is also fixed between the two retainers 42, and the tension bar 43 is connected to a tensioning plate (not shown in the figure) through a torsion spring (not shown in the figure). A mesh ring 45 is fitted on the negative pressure tube 4 and the tension bar 43 to prevent the yarn from being sucked into the negative pressure tube 4. A main gear ring 611 is provided on the surface of the front roller 61, and a driven gear ring 431 is provided on the surface of the tension bar 43. The bridge gear 44 simultaneously meshes the main gear ring 611 and the driven gear ring 431 to transmit the torque of the front roller 61 to the tension bar 43, so that the tension bar 43 drives the mesh ring 45 to rotate to pull the yarn. The bridge gear 44 is connected to a screw 441 that passes through the extension sleeve 2, and a nut fitted on the screw 441. The screw 441 abuts against the end of the roller seat 1 near the extension sleeve 2. That is, while the screw 441 and nut are fixing the gear, they also position the extension sleeve 2 and the roller seat 1.

[0035] In some embodiments, the roller seat 1 can contact the screw 441 through a recessed arcuate groove (not shown in the figure), and the arcuate groove and the screw 441 cooperate to further restrict the position of the roller seat 1.

[0036] Preferably, a locating pin 23 and a threaded fastener 24 are provided on the extension sleeve 2 perpendicular to the length direction of the roller seat 1. The locating pin 23 positions the extension sleeve 2 and the roller seat 1, or the extension sleeve 2 and the flute bracket 3. The threaded fastener 24 can be a bolt or nut to fix the extension sleeve 2 and the roller seat 1, or the extension sleeve 2 and the flute bracket 3.

[0037] The specific workflow of this utility model is as follows: When assembling the traction assembly, negative pressure tube 4, and suction flute tube 5 of the compact spinning process, the extension sleeve 2 is fixed to the roller seat 1 using threaded fasteners 24, and then the flute tube bracket 3 is fixed to the extension sleeve 2 using threaded fasteners 24. The bridge gear 44 is moved so that the screw 441 passes through the extension sleeve 2 and abuts against the roller seat 1. Then, the nut is connected to the end of the screw 441 away from the process gear, fixing the bridge gear 44 to the extension sleeve 2. The first slide 12 is moved so that the roller seat 1 engages in the first slide groove 121. The first slide 12 is adjusted to a predetermined position along the first slide groove 121. Then, the bolt extends along the connecting hole 122 of the first slide 12 into the fixing groove 14 and is connected to the nut, fixing the first slide 12 to the roller seat 1. Move the second slide block 13 so that the slide rail 22 engages with the second slide groove. Adjust the second slide block 13 to the predetermined position along the second slide groove. Then, insert the bolt into the fixing groove 14 through the through hole 221 and the connecting hole 122 of the second slide block 13, and connect the nut to fix the second slide block 13. Repeat the above actions to complete the configuration of the two sets of roller seats 1. Then, fix the rear roller 63 on the first slide block 12 in sequence, fix the middle roller 62 on the second slide block 13, fix the front roller 61 in the third slot 11, engage the negative pressure tube 4 and the second slot 21, and finally engage the suction tube 5 and the first slot 31. The bridge gear 44 simultaneously meshes the main gear ring 611 and the driven gear ring 431.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
