Description

Technical Field

[0001] This utility model relates to the field of spinning equipment technology, and in particular to a negative pressure module for compact spinning. Background Technology

[0002] Compared to ring spinning, which only has suction tubes, compact spinning adds a negative pressure tube. During yarn production, the negative pressure tube provides continuous negative pressure to adsorb the main fibers, allowing the short fibers and floating fibers at the edges of the main fibers to adhere tightly to the main guide bundle.

[0003] In existing compact spinning equipment, the negative pressure tube and the suction tube are independently installed on the spinning machine. When installing the negative pressure tube and the suction tube onto the spinning machine, the negative pressure tube assembly needs to be fixed on-site, and then the suction tubes are installed spindle by spindle, aligning the suction holes of the suction tubes with the negative pressure holes on the negative pressure tubes. Installation and debugging are relatively complex, and on-site assembly is prone to errors, affecting the spinning effect.

[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 a compact spinning negative pressure module to simplify the assembly of compact spinning.

[0006] The technical solution of this utility model is as follows: A compact spinning negative pressure module includes a support, negative pressure tubes, and suction tubes. The support is mounted on a spinning machine and has a negative pressure chamber inside. The negative pressure chamber is connected to a negative pressure source on the spinning machine. Negative pressure tubes are mounted on the support opposite the negative pressure chamber. Negative pressure holes are formed on the negative pressure tubes, connecting to the negative pressure chamber. Suction tubes are also mounted on the support opposite the negative pressure chamber. Suction holes are formed on the suction tubes, connecting to the negative pressure chamber.

[0007] A further technical solution involves creating an arc groove between the support and the negative pressure tube on the side facing the front roller, forming an arc transition.

[0008] A further technical solution involves creating tension holes on the support. An elastic element and a tension shaft parallel to the negative pressure pipe are installed within the tension holes. The tension shaft is positioned on the side of the elastic element furthest from the negative pressure pipe.

[0009] A further technical solution is that the elastic element is an elastic pressure plate.

[0010] A further technical solution involves creating a first positioning groove and a geothermal positioning groove along the radial direction of the tension shaft. An elastic element extends into the first positioning groove. The geothermal positioning groove is aligned with the negative pressure hole of the negative pressure pipe.

[0011] A further technical solution involves providing a cover on the negative pressure pipe. Adsorption holes are formed on the cover. These adsorption holes connect to the negative pressure chamber along the negative pressure hole.

[0012] A further technical solution involves installing a plug at the end of the negative pressure pipe furthest from the support. The plug seals the negative pressure pipe. Along the radial direction of the negative pressure pipe, the outer diameter of the plug is larger than the outer diameter of the negative pressure pipe.

[0013] A further technical solution involves extending a limiting protrusion along the radial direction of the suction tube. A limiting groove is provided on the bracket for the limiting protrusion to engage.

[0014] A further technical solution involves the bracket still having a rotating shaft and a locking part. The locking part connects to the rotating shaft. A locking groove is provided on the locking part, and a protrusion on the spinning machine engages with the locking groove.

[0015] A further technical solution involves installing a torsion spring on the rotating shaft. One end of the torsion spring contacts the bracket, and the other end of the torsion spring contacts the locking part.

[0016] The beneficial technical effects of this utility model are as follows: (1) In this utility model, the negative pressure module for compact spinning has the negative pressure tube and the suction tube centrally mounted on a support, with a negative pressure chamber on the support connecting the negative pressure tube and the suction tube. That is, the negative pressure tube and the suction tube are integrated as a single unit, and pre-assembly and debugging of the negative pressure tube, suction tube, and support are completed at the factory. During on-site installation, the entire structure of the support, negative pressure tube, and suction tube is fixed to the spinning machine, and the yarn is aligned, eliminating the need for alignment steps between the negative pressure tube and the suction tube, facilitating on-site assembly. Furthermore, the negative pressure tubes and suction tubes fixed on different supports work independently without interfering with each other, facilitating customized compact spinning. If a negative pressure tube or suction tube is damaged, it can be easily replaced, facilitating the maintenance of compact spinning.

[0017] (2) Furthermore, a tension shaft is also provided on the support to facilitate tensioning of the mesh ring on the negative pressure tube. The tension shaft, negative pressure tube and suction tube are all set on the support to form an integrated unit, which further improves the integration of the compact spinning negative pressure module. Pre-assembly improves the efficiency of on-site assembly, and customized compact spinning is more flexible.

[0018] (3) Furthermore, the bracket shaft is connected to a snap-fit ​​part, which is connected to the spinning machine to fix the bracket on the spinning machine. The shaft connection between the bracket and the snap-fit ​​part improves the flexibility of the bracket during installation. Attached Figure Description

[0025] Figure 1 A three-dimensional structural schematic diagram of a compact spinning negative pressure module according to an embodiment of the present disclosure is shown. Figure 2 A vertical cross-sectional view of the support structure in a compact spinning negative pressure module according to an embodiment of this disclosure is shown. Please refer to... Figure 1 and Figure 2A compact spinning negative pressure module includes a support 1, a negative pressure pipe 2, and a suction pipe 4. The support 1 is mounted on a spinning machine and has a negative pressure chamber 11 inside. The negative pressure chamber 11 is connected to a negative pressure source (not shown in the figure) on the spinning machine; the negative pressure source can be a fan. Specifically, a negative pressure source interface is pre-installed on the spinning frame, and the negative pressure chamber 11 and the negative pressure source are directly connected through this interface. The structure can be a flexible joint made of rubber. The orientation of the support 1 can be adjusted by the elastic deformation of the flexible structure, improving the installation flexibility of the support 1. On the support 1 opposite the negative pressure chamber 11, negative pressure pipes 2 are respectively installed. Negative pressure holes 21 are opened on the negative pressure pipes 2, connecting to the negative pressure chamber 11. On the support 1 opposite the negative pressure chamber 11, suction pipes 4 are respectively installed. Suction holes 41 are opened on the suction pipes 4, connecting to the negative pressure chamber 11. The negative pressure pipes 2 and suction pipes 4 are symmetrical structures arranged along the support 1, with the support 1 centrally supporting both the negative pressure pipes 2 and suction pipes 4. The support bracket 1 provides central support, preventing insufficient support on one side of the negative pressure tube 2 or the suction tube 4, thereby improving the stability of the support for the negative pressure tube 2 and the suction tube 4. The negative pressure tube 2 and the suction tube 4 are centrally mounted on the support bracket 1, and a negative pressure chamber 11 is provided on the support bracket 1 to connect the negative pressure tube 2 and the suction tube 4. That is, the negative pressure tube 2 and the suction tube 4 are integrated units, and the pre-assembly and debugging of the negative pressure tube 2, the suction tube 4 and the support bracket 1 are completed at the factory. During on-site installation, the overall structure of the support bracket 1, the negative pressure tube 2 and the suction tube 4 are fixed on the spinning machine, and the yarn is aligned, eliminating the need for alignment steps between the negative pressure tube 2 and the suction tube 4, which facilitates on-site assembly. Moreover, the negative pressure tube 2 and the suction tube 4 fixed on different supports 1 work independently without interfering with each other, which facilitates the customization of compact spinning. If a negative pressure tube 2 or the suction tube 4 is damaged, it can also be easily replaced, which facilitates the maintenance of compact spinning.

[0026] In other embodiments, the negative pressure tube 2 and the support 1 can be a separate structure, while the cotton suction tube 4 and the support 1 can be an integrated structure. This application does not limit this.

[0027] Figure 3 A schematic diagram of the internal structure of a compact spinning negative pressure module according to an embodiment of this disclosure is shown. Please refer to... Figure 1 and Figure 3Tension holes 13 are provided on the support 1. An elastic element 6 and a tension shaft 7 parallel to the negative pressure tube 2 are disposed within the tension hole 13. The tension shaft 7 is located on the side of the elastic element 6 away from the negative pressure tube 2. A mesh ring (not shown in the figure) fitted onto the negative pressure tube 2 is simultaneously fitted onto the tension shaft 7. Under the action of the elastic element 6, the tension shaft 7 tensions the mesh ring on the negative pressure tube 2. The tensioning of the mesh ring eliminates the gap between the mesh ring and the negative pressure tube 2, preventing negative pressure leakage. The tension shaft 7, negative pressure tube 2, and suction tube 4 are all assembled on the support 1 to form an integrated unit, further improving the integration of the compact spinning negative pressure module. Pre-assembly improves the efficiency of on-site assembly, and customized compact spinning is more flexible. In some embodiments, a groove can also be provided within the tension hole 13, with the elastic element 6 disposed within the groove, limiting the relative position between the elastic element 6 and the support 1.

[0028] Preferably, the elastic element 6 is an elastic pressure plate. Specifically, the elastic pressure plate is bent at an acute angle, with the acute angle facing away from the negative pressure pipe 2. The tension shaft 7 is positioned inside the acute angle to open it. The stretched and deformed elastic pressure plate is in an open and deformed state. Under the action of elastic force, the elastic pressure tends to restore the angle of the acute angle, thereby pushing the tension shaft 7 away from the negative pressure pipe 2, and the tension shaft 7 tensions the mesh ring.

[0029] More preferably, a first positioning groove 71 and a second positioning groove 72 are formed on the tension shaft 7 along its radial direction. The elastic member 6 extends into the first positioning groove 71. The first positioning groove 71 restricts the axial position of the elastic member 6 and the tension shaft 7, enhancing the stability of the tension shaft 7. The second positioning groove 72 is aligned with the negative pressure hole 21 of the negative pressure pipe 2. When the mesh ring is wound on the tension shaft 7, it can be engaged in the second positioning groove 72, preventing the mesh ring from sliding along the axial direction of the tension shaft 7 and enhancing the stability of the mesh ring.

[0030] Please refer to Figure 1 and Figure 2 On the side facing the front roller, an arc groove 12 is formed between the support 1 and the negative pressure tube 2. The front roller on the textile machine can be inserted into the arc groove 12, which restricts the relative position between the front roller and the support 1 and enhances the stability of the support 1 on the textile machine.

[0031] Preferably, a cover 3 is also provided on the negative pressure pipe 2. An adsorption hole 31 is formed on the cover 3. The adsorption hole 31 connects to the negative pressure chamber 11 along the negative pressure hole 21. The cover 3 and the negative pressure pipe 2, the plug 22 and the negative pressure pipe 2, and the suction tube 4 and the support 1 can all be bonded together. By replacing different covers 3 on the negative pressure pipe 2, different shapes of adsorption holes 31 can be used to adapt to different working conditions.

[0032] More preferably, a plug 22 is provided at the end of the negative pressure pipe 2 away from the support 1. The plug 22 seals the negative pressure pipe 2, and there can be an interference fit between the plug 22 and the negative pressure pipe 2. Along the radial direction of the negative pressure pipe 2, the outer diameter of the plug 22 is larger than the outer diameter of the negative pressure pipe 2. When the mesh ring is fitted onto the negative pressure pipe 2, the outer diameter of the plug 22 can contact the side of the mesh ring to limit the relative position between the mesh ring and the negative pressure pipe 2, prevent the mesh ring from slipping off the negative pressure pipe 2, and enhance the stability of the mesh ring fixation.

[0033] Please refer to Figure 3 A limiting protrusion 42 extends radially from the suction tube 4. A limiting groove (not shown in the figure) is provided on the bracket 1 for the limiting protrusion 42 to engage. Specifically, a hole (not shown in the figure) is provided on the bracket 1 for inserting the suction tube 4. The limiting groove is provided in the hole to restrict the rotation of the suction tube 4 relative to the bracket 1, fix the orientation of the suction tube 4, and ensure that the suction tube 4 faces the yarn.

[0034] Please refer to Figure 1 and Figure 3 The bracket 1 is also provided with a rotating shaft 51 and a snap-fit ​​part 5. The snap-fit ​​part 5 connects to the rotating shaft 51. A slot 53 is provided on the snap-fit ​​part 5, and a protrusion on the spinning machine is provided to engage with the slot 53. The slot 53 and the protrusion cooperate to position the bracket 1 and the spinning machine. In some embodiments, the bracket 1 and the spinning machine are also provided with corresponding screw holes 14, which facilitates the threaded fasteners (not shown in the figure) to fix the bracket 1 on the spinning machine, thereby enhancing the stability of the connection between the bracket 1 and the spinning machine.

[0035] Preferably, a torsion spring 52 is also provided on the rotating shaft 51. One end of the torsion spring 52 contacts the bracket 1, and the other end of the torsion spring 52 contacts the locking part 5. The locking part 5 and the bracket 1 rotate relative to each other, increasing the degree of freedom of the bracket 1 during installation and facilitating the installation of the bracket 1 on the spinning machine. The elastic force of the torsion spring 52 drives the locking part 5 to rotate around the bracket 1, and the locking part 5 cooperates with the bracket 1 to clamp the bracket 1 on the spinning machine.

[0036] The specific assembly process of this utility model is as follows: At the factory, plugs 22 are installed at both ends of the negative pressure pipe 2 to seal it. A cover 3 is installed on the negative pressure pipe 2. The suction pipe 4 and the bracket 1 are connected by insertion, connecting the suction pipe 4 and the negative pressure chamber 11. The elastic element 6 is inserted into the tension hole 13, and a tension shaft 7 is positioned along the tension hole 13. The elastic element 6 is simultaneously inserted into the first positioning groove 71. The tension shaft 7 is positioned on the side of the elastic element 6 away from the negative pressure pipe 2. Then, a mesh ring is fitted onto the negative pressure pipe 2 and the bracket 1. The outer edge of the mesh ring contacts the outer diameter of the plug 22, and the mesh ring is simultaneously inserted into the second positioning groove 72. Finally, the rotating shaft 51 and the torsion spring 52 connect the bracket 1 and the snap-fit ​​part 5. This completes the pre-assembly of the bracket 1 at the factory. During subsequent on-site installation of the bracket 1 on the spinning machine, the negative pressure chamber 11 is connected to the negative pressure source of the spinning machine. The protrusion on the spinning machine is snapped into the slot 53, and the bracket 1 is threaded onto the spinning machine through the screw hole 14. This completes the installation of a single compact spinning negative pressure module. Finally, based on the number of spindles on the spinning machine, repeat the above steps to fix the corresponding number of compact spinning negative pressure modules on the spinning machine, thus completing the assembly of the compact spinning negative pressure modules on the spinning machine.

[0037] 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.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the 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.
