Description

Technical Field

[0001] This utility model relates to the field of air-jet loom technology, specifically to a selvage device for textile air-jet looms. Background Technology

[0002] Air-jet looms are looms that use the high-speed airflow generated by releasing compressed air to pull the weft yarn through the weft hole to complete the weft insertion. The selvage device of an air-jet loom is a device used to treat the edge of the fabric during the weaving process. Its main function is to ensure that the edge of the fabric is neat and smooth, and to prevent problems such as unraveling and wear during subsequent processing or use.

[0003] Publication No. CN218115753U discloses a selvage device for air-jet looms, relating to the technical field of air-jet loom equipment. It includes a yarn guide seat with a rotating shaft at its top. A guide wheel is rotatably mounted on the side of the rotating shaft. Limiting rings are fixedly installed at both the top and bottom of the rotating shaft and the guide wheel. A first fixing ring and a second fixing ring are respectively fitted onto the top and bottom of the limiting rings on the rotating shaft. A first support rod is fixedly installed on one side of the first fixing ring, and an upper frame is fixedly installed on one side of the first support rod. A second support rod is fixedly installed on one side of the second fixing ring, and a lower frame is fixedly installed on one side of the second support rod. A yarn guide is provided between the upper and lower frames. Mounting blocks are fixedly installed on both sides of the bottom of the upper frame. The selvage device for air-jet looms described in this application has a simple structure, is easy to use, enhances connection stability, improves performance, and facilitates installation and disassembly.

[0004] The aforementioned patent addresses the shortcomings of existing edge guides, where the yarn exerts a certain force on the yarn guide during the yarn guiding process. Due to the poor connection strength between the yarn guide and the guide wheel, the yarn vibrates during transmission, easily causing wear. However, this patent uses nuts to limit and fix the first and second fixing rings. The nut fixing method makes the disassembly and installation of the yarn guide relatively cumbersome. In case of yarn breakage or yarn guide failure, it becomes difficult to quickly replace the yarn guide, which can easily affect production efficiency. Furthermore, the maintenance process relies on specialized tools, which not only increases maintenance costs but also makes maintenance impossible if the tools are missing or damaged. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a selvage device for a textile air-jet loom, which has the advantage of facilitating the maintenance of the yarn guide. It solves the problem that in the existing technology, the yarn guide uses nuts to limit and fix the first and second fixing rings, and special tools are required to disassemble the nuts when replacing or maintaining the yarn guide, resulting in poor maintenance efficiency and convenience.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a selvage device for a textile air-jet loom, comprising a fixed base, a rotating yarn guide, and a yarn guide wheel, wherein the fixed base is provided with a fixing mechanism for limiting and fixing the yarn guide and the yarn guide wheel;

[0007] The fixing mechanism includes a side plate fixedly installed on the surface of the fixed base. A rectangular hollow cylinder is fixedly installed on the surface of the side plate. An internally threaded cylinder is slidably installed inside the rectangular hollow cylinder. A threaded post is threadedly connected inside the internally threaded cylinder. A connecting rod extending to the outside of the rectangular hollow cylinder is rotatably installed on the top of the internally threaded cylinder. A retaining strip is fixedly installed on the top of the connecting rod. A limit sleeve is fixedly installed at one end of the retaining strip. A retaining groove is opened on the surface of the side plate.

[0008] Furthermore, a first fixed cylinder and a second fixed cylinder are sleeved on the surface of the rotating shaft, and a fixed rod is fixedly installed on the surface of both the first fixed cylinder and the second fixed cylinder. The yarn guide is fixedly installed at the end away from the fixed rod, and the yarn guide wheel is sleeved on the surface of the rotating shaft and located between the first fixed cylinder and the second fixed cylinder.

[0009] Furthermore, a groove is provided on the surface of the rotating shaft, and a limiting slide bar that is inserted into the groove is fixedly installed on the inner surface of the first and second fixed cylinders.

[0010] Furthermore, a limiting ring is fixedly installed on the surface of the rotating shaft, and the bottom of the second fixed cylinder is in contact with the limiting ring.

[0011] Furthermore, bearings are fixedly installed on the opposite side surfaces of the first and second fixed cylinders, and the bearings are in contact with the yarn guide wheel.

[0012] Furthermore, a rotating rod extending to the outside of the rectangular hollow cylinder is fixedly installed at the bottom of the threaded column, and a rotating knob is fixedly installed at the bottom of the rotating rod, and the rotating knob is rotatably connected to the bottom of the rectangular hollow cylinder.

[0013] Furthermore, a rectangular limiting frame is fixedly installed on the outer surface of the internally threaded cylinder. The rectangular limiting frame is adapted to the rectangular hollow cylinder, and the surface of the rectangular limiting frame is in sliding contact with the inner surface of the rectangular hollow cylinder.

[0014] Furthermore, the limiting sleeve is adapted to the rotating shaft, and the locking strip is adapted to the locking groove.

[0015] Furthermore, the fixed base has mounting holes on its surface, and the number of mounting holes is multiple and evenly distributed on the surface of the fixed base.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] This selvage device for textile air-jet looms uses a threaded connection between an internal threaded cylinder and a threaded column to raise and lower the connecting rod, locking strip, and limiting sleeve. This enables quick limiting and fixing of the yarn guide and yarn guide wheel. When the yarn guide needs to be replaced or maintained, the limiting sleeve can be easily fixed and released simply by rotating the knob, without the need for professional tools, thus significantly improving the maintenance efficiency and convenience of the yarn guide.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4This embodiment provides a selvage device for a textile air-jet loom, comprising a fixed base 1, a rotating shaft 2, a yarn guide 3, and a yarn guide wheel 4. The fixed base 1 has multiple mounting holes 22 evenly distributed on its surface. The fixed base 1 also has a fixing mechanism for limiting and fixing the yarn guide 3 and the yarn guide wheel 4. This fixing mechanism includes a side plate 5 fixedly mounted on the surface of the fixed base 1, and a rectangular hollow cylinder 6 fixedly mounted on the surface of the side plate 5. An internally threaded cylinder 7 is slidably installed inside. A threaded post 8 is threadedly connected inside the internally threaded cylinder 7. A connecting rod 9 extending to the outside of a rectangular hollow cylinder 6 is rotatably installed on the top of the internally threaded cylinder 7. A retaining strip 10 is fixedly installed on the top of the connecting rod 9. A limiting sleeve 11 is fixedly installed on one end of the retaining strip 10. A retaining groove 12 is opened on the surface of the side plate 5. The limiting sleeve 11 is adapted to the rotating shaft 2. The retaining strip 10 is adapted to the retaining groove 12, so that the limiting sleeve 11 can be sleeved on the surface of the rotating shaft 2 and the retaining strip 10 can be inserted into the retaining groove 12.

[0025] Among them, a rotating rod 23 extending to the outside of the rectangular hollow cylinder 6 is fixedly installed at the bottom of the threaded column 8. A rotating knob 20 is fixedly installed at the bottom of the rotating rod 23. The rotating knob 20 is rotatably connected to the bottom of the rectangular hollow cylinder 6. The rotating rod 23 and the rotating knob 20 facilitate the rotation of the threaded column 8. A rectangular limiting frame 21 is fixedly installed on the outer surface of the inner threaded cylinder 7. The rectangular limiting frame 21 is adapted to the rectangular hollow cylinder 6. The surface of the rectangular limiting frame 21 is in sliding contact with the inner surface of the rectangular hollow cylinder 6.

[0026] It should be noted that a first fixed cylinder 13 and a second fixed cylinder 14 are sleeved on the surface of the rotating shaft 2. A fixed rod 15 is fixedly installed on the surface of both the first fixed cylinder 13 and the second fixed cylinder 14. The yarn guide 3 is fixedly installed at the end away from the fixed rod 15. The yarn guide wheel 4 is sleeved on the surface of the rotating shaft 2 and is located between the first fixed cylinder 13 and the second fixed cylinder 14.

[0027] The rotating shaft 2 has a groove 16 on its surface. The inner surfaces of the first fixed cylinder 13 and the second fixed cylinder 14 are fixedly installed with limiting slide strips 17 that are inserted into the groove 16. The rotating shaft 2 has a limiting ring 18 fixedly installed on its surface. The bottom of the second fixed cylinder 14 is in contact with the limiting ring 18.

[0028] It should be noted that bearings 19 are fixedly installed on the opposite side surfaces of the first fixed cylinder 13 and the second fixed cylinder 14. The bearings 19 are in contact with the guide wheel 4, which facilitates the rotation of the guide wheel 4 between the rotating shaft 2 and the first fixed cylinder 13 and the second fixed cylinder 14.

[0029] The working principle of the above embodiments is as follows:

[0030] In use, the second fixed cylinder 14, the guide wheel 4, and the first fixed cylinder 13 are sequentially fitted onto the surface of the rotating shaft 2, so that the limiting slide bar 17 is engaged in the slide groove 16 to limit the second fixed cylinder 14 and the first fixed cylinder 13. At this time, the guide wheel 4 is located between the second fixed cylinder 14 and the first fixed cylinder 13 and is in contact with the bearing 19. Then, the locking bar 10 and the connecting rod 9 are rotated so that the locking bar 10 corresponds to the locking groove 12. Then, the threaded column 8 is rotated by rotating the knob 20 and the rotating rod 23. The threaded column 8 drives the internal threaded cylinder 7 to move downward in the rectangular hollow cylinder 6, so that the locking bar 10 and the connecting rod 9 can follow the internal thread. The cylinder 7 moves downward, causing the limiting sleeve 11 to gradually move downward and fit onto the rotating shaft 2 until the limiting sleeve 11 is in close contact with the top of the first fixed cylinder 13. This allows for the limiting and fixing of the second fixed cylinder 14, the guide wheel 4, and the first fixed cylinder 13. The internal thread cylinder 7 can be limited by the rectangular limiting frame 21. During disassembly, simply move the limiting sleeve 11 upward to separate the retaining strip 10 from the retaining groove 12 and rotate the retaining strip 10 and the limiting sleeve 11 so that the limiting sleeve 11 is misaligned with the rotating shaft 2. This allows the second fixed cylinder 14, the guide wheel 4, and the first fixed cylinder 13 to be removed from the rotating shaft 2.
