Description

Technical Field

[0001] This utility model relates to the field of textile processing technology, specifically to a tension-adjustable guide wheel assembly for textile machinery. Background Technology

[0002] One of the most essential steps in yarn processing is yarn guiding, which involves guiding the yarn wound on the bobbin for further processing according to the processing requirements. Guide wheels are used for guiding the yarn and are commonly found in the yarn guiding devices of textile machinery. These guide wheels play a role in guiding the core yarn during the spinning process, assisting in the weaving process. Existing technology discloses a guide wheel that is easy to replace (application number 202322968430.X). This guide wheel is assembled using a snap-fit ​​method, making it easy to install and disassemble.

[0003] However, in the actual yarn guiding process, different yarns require different guiding tensions. During the guiding process, it is not possible to ensure that the yarn is in a taut state, which can easily cause the yarn to not make sufficient contact with the guide wheel, affecting the actual guiding effect of the yarn. It can also cause the yarn to tangle when it is loose. Summary of the Invention

[0006] The telescopic end inside the fixed sleeve is connected to a telescopic rod. The wheel frame is fixedly connected to the end of the telescopic rod, and the other end of the telescopic rod is fixedly connected to a connecting rod. A tension spring is sleeved on the outside of the connecting rod. The end of the fixed sleeve is fixedly connected to a fixed plate. A threaded rod is provided in the middle of the fixed plate. One end of the threaded rod is connected to an adjusting nut, and the other end of the threaded rod is screwed into an adjusting screw hole opened inside the connecting rod.

[0007] As a preferred technical solution of the adjustable tension guide wheel assembly for textile machinery according to this utility model, the guide frame is fixedly installed at the guide position of the textile machinery by the mounting seat at its side end. The yarn passes through the guide holes on both sides of the guide frame and contacts the yarn groove at the side of the guide wheel.

[0008] As a preferred technical solution of the adjustable tension guide wheel assembly for textile machinery of this utility model, one end of the tension spring is fixedly connected to the top of the telescopic rod, and the other end is fixedly connected to the inner wall of the fixed plate.

[0009] As a preferred technical solution of the adjustable tension guide wheel assembly for textile machinery of this utility model, the fixed plate is provided with a through hole for the threaded rod to pass through, and the threaded rod passes through the through hole and is screwed into the adjusting screw hole by threads.

[0010] As a preferred technical solution of the adjustable tension guide wheel assembly for textile machinery of this utility model, the side end of the guide frame is located at the yarn inlet position and is detachably mounted with a mounting sleeve by means of a disassembly ring seat. Rubber scraper heads are evenly arranged on the inner side of the mounting sleeve.

[0011] Negative pressure pipes are connected through both sides of the mounting sleeve. One end of the negative pressure pipe extending to the inside of the mounting sleeve is connected to a gas collection box, and the other end of the negative pressure pipe is connected to a central pipe. The end of the central pipe is connected to the top of the central box. A negative pressure fan is installed at the bottom inside the central box, and a slidable accumulation box is embedded in the top inside the central box. An interception net is provided at the bottom inside the accumulation box.

[0012] As a preferred technical solution of the adjustable tension guide wheel assembly for textile machinery of this utility model, the disassembly ring seat is detachably connected to the inner wall of the guide wire frame by screws, and the center of the disassembly ring seat and the center of the guide wire hole at the infeed position are on the same straight line.

[0013] As a preferred technical solution of the adjustable tension guide wheel assembly for textile machinery of this utility model, the air collection box is arranged laterally on the inner side of the mounting sleeve, the negative pressure pipe and the concentrating pipe are detachably connected through a detachable pipe head, and the accumulation box and the inner wall of the concentrating box are tightly fitted together.

[0014] Compared with the prior art, this utility model provides a tension-adjustable guide wheel assembly for textile machinery, which has the following advantages:

[0015] 1. The tension spring inside the fixed sleeve provides elastic support for the telescopic rod, ensuring that the end wheel frame and guide wheel are in close contact with the wire under elastic support. The multiple sets of elastically connected guide wheels ensure that the wire is in close contact with the guide wheels after passing through them, preventing the wire from becoming loose or tangled, and effectively guiding the wire for subsequent processing.

[0016] By using the threaded rod and adjusting nut connected inside the fixed plate, combined with the connecting rod at the end of the telescopic rod and the adjusting screw hole inside the connecting rod, the position of the connecting rod can be easily adjusted by rotating the threaded rod. This facilitates the adjustment of the tension support force of the tension spring, allowing for adjustment of the elastic support force according to different types of wire strength. This ensures that the elastic tension force of the guide wheel can adapt to the wire strength, preventing wire breakage while ensuring its guiding effect.

[0017] 2. By installing a round sleeve at the guide hole where the yarn enters, and with the rubber scraper head inside, the broken yarn and lint covering the outside of the yarn can be scraped off when the yarn enters by the scraping contact between the rubber scraper head and the outside of the yarn. This prevents the broken yarn and lint from getting tangled on the outside of the guide wheel and affecting its rotation, while improving the overall quality of the yarn after it is guided and combed.

[0018] The negative pressure fan, central pipe, negative pressure pipe, and collection box facilitate the negative pressure collection of broken threads and lint scraped from the disassembled ring seat, preventing the threads and lint from accumulating in the installation sleeve. At the same time, the collection box, combined with the interception net at the bottom of the collection box, facilitates the collection of broken threads and lint by drawing them into the collection box for centralized collection, making subsequent centralized cleaning convenient.

[0030] Example: Please refer to Figure 1-6 This utility model provides the following technical solution: a tension-adjustable guide wheel assembly for textile machinery, including a guide frame 1, four sets of mounting seats 2 symmetrically installed on the back side of the guide frame 1, and guide holes 3 are provided at the inlet and outlet positions on both sides of the guide frame 1. Fixed sleeves 4 are fixedly installed on the top two sides and the middle of the bottom of the guide frame 1, and wheel frames 5 are connected to the telescopic ends of the fixed sleeves 4. Guide wheels 6 are rotatably connected to the inner side of the wheel frames 5. The edge of the guide wheel 6 is provided with a wire groove 7. The guide frame 1 is fixedly installed at the guide position of the textile machinery through the mounting seats 2 at its edge. The wire passes through the guide holes 3 on both sides of the guide frame 1 and contacts the wire groove 7 on the edge of the guide wheel 6, which facilitates the stable installation and use of the guide frame 1 and facilitates the feeding of the wire.

[0031] The telescopic end inside the fixed sleeve 4 is connected to a telescopic rod 8. The wheel frame 5 is fixedly connected to the end of the telescopic rod 8, and the other end of the telescopic rod 8 is fixedly connected to a connecting rod 9. A tension spring 10 is sleeved on the outside of the connecting rod 9. A fixed plate 11 is fixedly connected to the end of the fixed sleeve 4. One end of the tension spring 10 is fixedly connected to the top of the telescopic rod 8, and the other end is fixedly connected to the inner wall of the fixed plate 11, which facilitates the connection and fixation of the tension spring 10. A threaded rod 12 is provided in the middle of the fixed plate 11. One end of the threaded rod 12 is connected to an adjusting nut 13, and the other end of the threaded rod 12 is screwed into the adjusting screw hole 14 opened inside the connecting rod 9. The fixed plate 11 is provided with a through hole for the threaded rod 12 to pass through. The threaded rod 12 passes through the through hole and is screwed into the adjusting screw hole 14 by threads, which facilitates the connection of the threaded rod 12. By rotating the threaded rod 12, the position of the connecting rod 9 can be easily adjusted.

[0032] The side end of the conductor frame 1 is located at the wire inlet position and can be detachably installed with the mounting sleeve 15 via the disassembly ring seat 16. The disassembly ring seat 16 is detachably connected to the inner wall of the conductor frame 1 by screws. The center of the disassembly ring seat 16 and the center of the wire guide hole 3 at the wire inlet position are on the same straight line, which facilitates the installation of the disassembly ring seat 16 and makes the mounting sleeve 15 easy to install and remove, and facilitates the precise feeding of the wire. Rubber scraper heads 17 are evenly arranged on the inner side of the mounting sleeve 15.

[0033] Negative pressure pipes 18 are connected through both sides of the mounting sleeve 15. One end of the negative pressure pipe 18 extends to the inside of the mounting sleeve 15 and is connected to a gas collection box 19. The other end of the negative pressure pipe 18 is connected to a central pipe 20. The end of the central pipe 20 is connected to the top of the central box 21. A negative pressure fan 22 is installed at the bottom inside the central box 21. An accumulation box 23 is slidably connected to the top inside the central box 21. The gas collection box 19 is arranged horizontally inside the mounting sleeve 15. The negative pressure pipe 18 and the central pipe 20 are detachably connected through a detachable pipe head. The accumulation box 23 is tightly fitted to the inner wall of the central box 21, which facilitates the negative pressure collection of broken threads and lint scraped from the disassembly ring seat 16, preventing the accumulation of broken threads and lint in the mounting sleeve 15, making the connection between the negative pressure pipe 18 and the central pipe 20 convenient, and ensuring the airtightness inside the central box 21. An interception net 24 is provided at the bottom inside the accumulation box 23.

[0034] The working principle and usage process of this utility model are as follows: During the yarn guiding process, the wire guide 1 is first installed through the mounting base 2, so that the wire guide 1 is fixedly installed in the yarn guiding position of the textile machinery through the mounting base 2 at its side end, so that the yarn passes through the yarn guiding holes 3 on both sides of the wire guide 1 and contacts the yarn groove 7 on the side of the yarn guiding wheel 6, which facilitates the stable installation and use of the wire guide 1 and facilitates the yarn guiding.

[0035] When the yarn enters through the guide hole 3 at the yarn inlet of the wire frame 1, a circular sleeve 15 is installed at the guide hole 3 at the yarn entry position. In conjunction with the rubber scraper head 17 inside, the broken yarn and lint covering the outside of the yarn can be scraped off by the scraping contact between the rubber scraper head 17 and the outside of the yarn when the yarn enters. This prevents the broken yarn and lint from getting tangled on the outside of the guide wheel 6 and affecting its rotation, while improving the overall quality of the yarn after being guided and combed.

[0036] Meanwhile, after the rubber scraper head 17 removes the broken threads and lint, the negative pressure fan 22 is started. In conjunction with the central pipe 20, the negative pressure pipe 18 and the collection air box 19, the broken threads and lint in the disassembly ring seat 16 are collected under negative pressure. The interception net 24 at the bottom of the accumulation box 23 is used to draw the broken threads and lint into the accumulation box 23 for centralized collection, which is convenient for subsequent centralized cleaning.

[0037] When the wire is guided by the guide wheel 6 in the wire frame 1, the tension spring 10 provides elastic support for the telescopic rod 8, so that the wheel frame 5 and the guide wheel 6 at the end of the telescopic rod 8 can be in close contact with the wire under the action of elastic support. Moreover, the guide wheel 6 connected by multiple sets of elastic support ensures that the wire can be in close contact with the guide wheel 6 after passing through multiple sets of guide wheels 6, avoiding the wire from becoming loose and preventing tangling.

[0038] When it is necessary to adjust the elastic support strength of the guide wheel 6, the threaded rod 12 and adjusting nut 13 connected inside the fixed plate 11 are used, combined with the connecting rod 9 at the end of the telescopic rod 8 and the adjusting screw hole 14 inside the connecting rod 9. The position of the connecting rod 9 is adjusted by rotating the threaded rod 12, which facilitates the adjustment of the tension support force of the tension spring 10. It is convenient to adjust the elastic support force according to the strength of different types of wires, so that the elastic tension of the guide wheel 6 can adapt to the strength of the wire, prevent wire breakage, and ensure that it has excellent guiding effect.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
