Technical Field

[0001] This utility model belongs to the field of air-bearing traction for rapier looms, and specifically relates to an air-bearing traction mechanism for rapier looms. Background Technology

[0002] In the textile industry, the rapier loom, as a mainstream shuttleless loom, is widely used in the production of various fabrics due to its high speed, high degree of automation and high efficiency. Its active weft insertion method is highly adaptable to yarn varieties and has significant advantages in multi-color weft weaving, capable of producing yarn-dyed products with up to 16 weft yarns. However, traditional rapier looms have many problems in the fabric traction process.

[0003] The conventionally designed guide rail and sword shaft experience frequent friction, leading to severe wear on both surfaces and significantly impacting the machine's lifespan. The gear and rack transmission mechanism is complex, with difficult-to-machine parts, prone to wear, and difficult to maintain. Furthermore, the lack of effective positioning at the sword shaft's tail results in poor operational stability, further exacerbating wear. Utility Model Content

[0007] As a preferred technical solution, the mounting component includes a snap-fit ​​block disposed on the upper end of the mounting base, a snap-fit ​​frame fixedly connected to the lower end of the operating needle, a snap-fit ​​hole being provided on the inner side of the snap-fit ​​frame, and the snap-fit ​​frame and the snap-fit ​​block being inserted into each other.

[0008] As a preferred technical solution, circular grooves are provided on both sides of the snap-fit ​​block, and snap-fit ​​springs are fixedly connected inside the circular grooves. A snap-fit ​​connector is fixedly connected to the other end of the snap-fit ​​spring, and the snap-fit ​​connector and the snap-fit ​​hole snap-fit ​​each other.

[0009] As a preferred technical solution, release springs are fixedly connected to both sides of the snap-fit ​​frame on both sides of the snap-fit ​​hole, and a pressing plate is fixedly connected to the other end of the release spring. A release block is fixedly connected to the inner side of the pressing plate, and the release block is inserted into the snap-fit ​​hole.

[0010] As a preferred technical solution, the lower end of the operating needle is fixedly connected to an installation edge, the outer surface of the installation edge is provided with an installation through hole, an installation screw is inserted into the installation through hole, and the installation screw passes through the installation through hole and is threadedly connected to the snap-fit ​​frame.

[0011] As a preferred technical solution, the lower end of the mounting base is slidably connected to the upper end of the guide rail frame, and a limit slider is fixedly connected to the lower end of the mounting base. Limit grooves are provided on both sides of the upper end of the guide rail frame, and the limit grooves and limit sliders are slidably connected to each other.

[0012] As a preferred technical solution, the lower end of the flexible sword shaft is provided with a fixing through hole, and a fixing screw is inserted into the fixing through hole. The fixing screw passes through the fixing through hole and is threadedly connected to the mounting base.

[0013] In summary, the present invention has the following main advantages:

[0014] First, when the air-bearing traction mechanism of this rapier loom is in use, the air pump delivers airflow to the air inlet chamber through the connecting pipe, and then distributes it evenly to the air outlet frame in the guide rail frame through the distribution pipe. Finally, the air is sprayed out by the air outlet head to form an air film. At the same time, the traction wheel drives the flexible rapier to move in the guide rail frame. The air film can reduce the direct friction between the flexible rapier and the guide rail frame. It works with the mounting base and operating needle to complete actions such as weft insertion. The air-bearing component reduces component wear through airflow buffering and extends the equipment life. The non-contact support makes the flexible rapier run more smoothly and reduces the impact of vibration on weft insertion accuracy. At the same time, it avoids the problems of rapier jamming or fabric damage that may occur in traditional mechanical traction, improves weaving stability and fabric quality, and is especially suitable for high-speed weaving scenarios.

[0015] Secondly, when installing the operating needle, the snap-fit ​​block is inserted into the snap-fit ​​frame. During insertion, the snap-fit ​​connector is squeezed into the circular groove. After the snap-fit ​​block is fully inserted into the snap-fit ​​frame, the position of the snap-fit ​​hole aligns with the position of the circular groove. At this point, the snap-fit ​​connector will pop out of the circular groove under the action of the snap-fit ​​spring, allowing the snap-fit ​​connector to engage with the snap-fit ​​hole, thus achieving the snap-fit ​​effect and enabling the installation of the operating needle. Through the insertion and engagement of the snap-fit ​​block and the snap-fit ​​frame, and the automatic snap-fit ​​of the snap-fit ​​connector, the operating needle can be installed quickly without the need for additional tools, simplifying the installation process and improving assembly efficiency. The continuous elasticity provided by the snap-fit ​​spring ensures that the snap-fit ​​connector and the snap-fit ​​hole are tightly engaged, making the structure of the operating needle stable after installation and not easy to loosen. This effectively avoids problems such as weft insertion deviation caused by needle shaking during weaving, ensuring the stability of equipment operation. Attached Figure Description

An air inlet chamber 85 is fixedly connected to the other end of the connecting pipe 84. Multiple diverter pipes 86 are fixedly connected to the other end of the air intake chamber 85. An air outlet frame 81 is fixedly connected inside the guide rail frame 1. An air outlet head 82 is fixedly connected inside the air outlet frame 81. The diverter pipes 86 pass through the guide rail frame 1 and are fixedly connected to the air outlet frame 81. An installation edge 14 is fixedly connected to the lower end of the operating needle 7. An installation through hole 15 is opened on the outer surface of the installation edge 14. An installation screw 16 is inserted into the installation through hole 15. The installation screw 16 passes through the installation through hole 15 and is threadedly connected to the snap-fit ​​frame 65. A fixing through hole 17 is opened at the lower end of the flexible sword rod 4. A fixing screw 18 is inserted into the fixing through hole 17. The fixing screw 18 passes through the fixing through hole 17 and is threadedly connected to the mounting base 5.

[0024] refer to Figures 1-4 The mounting component 6 includes a snap-fit ​​block 61 located on the upper end of the mounting base 5. A snap-fit ​​frame 65 is fixedly connected to the lower end of the operating needle 7. A snap-fit ​​hole 66 is provided on the inner side of the snap-fit ​​frame 65. The snap-fit ​​frame 65 and the snap-fit ​​block 61 are interlocked. Circular grooves 62 are provided on both sides of the snap-fit ​​block 61. A snap-fit ​​spring 63 is fixedly connected inside the circular groove 62. A snap-fit ​​connector 64 is fixedly connected to the other end of the snap-fit ​​spring 63. The snap-fit ​​connector 64 is interlocked with the snap-fit ​​hole 66. When the snap-fit ​​block 61 is inserted into the snap-fit ​​frame 65, the snap-fit ​​connector 64 is squeezed into the circular groove 62. After the snap-fit ​​block 61 is fully inserted into the snap-fit ​​frame 65, the position of the snap-fit ​​hole 66 is aligned with the position of the circular groove 62. At this time, the snap-fit ​​connector 64 will pop out of the circular groove 62 under the action of the snap-fit ​​spring 63, so that the snap-fit ​​connector 64 is interlocked with the snap-fit ​​hole 66, thereby achieving the snap-fit ​​effect and allowing the operating needle 7 to be installed.

[0025] refer to Figure 4Both sides of the snap-fit ​​frame 65 are fixedly connected to release springs 11 on both sides of the snap-fit ​​hole 66. The other end of the release spring 11 is fixedly connected to a pressing plate 12. The inner side of the pressing plate 12 is fixedly connected to a release block 13. The release block 13 is inserted into the snap-fit ​​hole 66. By pressing the pressing plate 12 inward, the release block 13 moves into the snap-fit ​​hole 66. After the release block 13 enters the snap-fit ​​hole 66, it can squeeze out the snap-fit ​​connector 64. After the snap-fit ​​connector 64 is disengaged from the snap-fit ​​hole 66, the operating needle 7 can be easily disassembled.

[0026] refer to Figure 2 The lower end of the mounting base 5 is slidably connected to the upper end of the guide rail frame 1. The lower end of the mounting base 5 is fixedly connected to the limit slider 10. The upper end of the guide rail frame 1 has limit grooves 69 on both sides. The limit grooves 69 and the limit sliders 10 are slidably connected to each other. The limit grooves 69 and the limit sliders 10 can limit the mounting base 5, so that the sliding is more stable when using the operating needle 7.

[0027] Operating principle and advantages: In use, the operating needle 7 is installed by inserting the locking block 61 into the locking frame 65. During insertion, the locking connector 64 is compressed into the circular groove 62. After the locking block 61 is fully inserted into the locking frame 65, the locking hole 66 aligns with the circular groove 62. At this point, the locking connector 64 is ejected from the circular groove 62 under the action of the locking spring 63, allowing it to engage with the locking hole 66, thus achieving the locking effect. This allows the operating needle 7 to be installed. After installation, the device can be used normally. During use, the air pump 83 delivers air through the connecting pipe 84... Airflow is delivered to the air inlet chamber 85, and then evenly distributed to the air outlet frame 81 within the guide rail frame 1 via the diverter pipe 86. Finally, it is ejected from the air outlet head 82 to form an air film. At the same time, the traction wheel 3 drives the flexible rapier 4 to move within the guide rail frame 1. The air film reduces the direct friction between the flexible rapier 4 and the guide rail frame 1. Together with the mounting base 5 and the operating needle 7, it completes actions such as weft insertion. The air flotation component 8 reduces component wear and extends equipment life through airflow buffering. The non-contact support makes the flexible rapier 4 run more smoothly, reducing the impact of vibration on weft insertion accuracy. At the same time, it avoids the problems of rapier jamming or fabric damage that may occur in traditional mechanical traction, thus improving weaving stability and fabric quality.
