Description

Technical Field

[0001] This utility model relates to the field of loom technology, and in particular to a guiding mechanism for a wide-width water jet loom. Background Technology

[0002] The wide-width water jet loom is a shuttleless loom that uses high-pressure water jets as the weft insertion medium. Its width typically exceeds 2.8 meters, far surpassing that of ordinary looms. During operation, it uses water jets to precisely carry the weft yarn through the warp opening area, completing the weft insertion action with high speed and stability. This type of loom boasts advantages such as high production efficiency and low energy consumption. Water jet weft insertion reduces yarn wear and improves fabric surface smoothness. It is highly compatible with hydrophobic yarns such as synthetic fibers and is widely used in the production of wide-width fabrics such as curtain fabrics, decorative fabrics, and industrial fabrics. With its high degree of automation and ease of operation, it has become a core piece of equipment in the modern textile industry for wide-width fabric production.

[0003] When transporting fabrics on existing wide-width water-jet looms, the fabric often deviates from the correct transport position, directly affecting the processing quality. When limiting the fabric on both sides, the contact parts are made of hard materials, which can cause scratches and damage to the fabric surface, affecting the product appearance.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] Reference Figure 1-4 A guiding mechanism for a wide-width water jet loom includes a fixed frame 1, a lifting frame 2 at the bottom of the fixed frame 1, and adjusting components 3 symmetrically arranged at both ends of the rear side of the lifting frame 2. The adjusting assembly 3 includes an air collecting plate 4, a swing frame 5, a first air blowing end 6, a second air blowing end 7, a gear 8, a rack 9, and a first cylinder 10. Two swing frames 5 are rotatably connected to adjacent sides of the two air collecting plates 4. Each swing frame 5 has a first air blowing end 6 on its surface, located above and below the second air blowing end 7 respectively. Both the first air blowing ends 6 and the second air blowing end 7 are connected to the interior of the air collecting plate 4. A gear 8 is fixedly connected to the rear side of each swing frame 5, and a first cylinder is fixedly connected to the upper and lower ends of the rear side of the air collecting plate 4. 10. Each of the two first cylinders 10 has a rack 9 fixedly connected to its output end on an adjacent side. Both racks 9 are slidably connected to the rear side of the air collecting plate 4. The racks 9 are meshed with the adjacent gears 8. Specifically, when the first cylinder 10 extends or retracts, it drives the racks 9 to slide along the rear side of the air collecting plate 4. Through the meshing transmission between the racks 9 and the gears 8, it drives the two first blowing ends 6 to swing around the rotation connection point with the air collecting plate 4, thereby adjusting the tilt angle of the first blowing ends 6. Together with the second blowing end 7 with a fixed angle, a gradient airflow is formed to flexibly guide the edge of the fabric.

[0018] Furthermore, a movable groove 12 is provided on the rear side of the lifting frame 2. A bidirectional lead screw 13 is rotatably connected between the inner walls of the two sides of the movable groove 12. A motor 14 is fixedly connected to the other side of the lifting frame 2. The output end of the motor 14 is fixedly connected to the other end of the bidirectional lead screw 13 through the lifting frame 2. Specifically, after the motor 14 starts, it drives the bidirectional lead screw 13 to rotate in the movable groove 12. Utilizing the thread transmission characteristics of the bidirectional lead screw 13, it drives the sliders 15 at both ends to slide synchronously in opposite directions along the movable groove 12. Then, the distance between the two adjustment components 3 is adjusted by the connecting frame 16 to adapt to fabrics of different widths.

[0019] Furthermore, both ends of the bidirectional lead screw 13 are threaded with sliders 15, which are slidably connected inside the movable groove 12. Each slider 15 is fixedly connected to a connecting frame 16 on its rear side. Specifically, the sliders 15 are rigidly connected to the air collecting plate 4 through the connecting frame 16 to ensure the stability of the adjusting component 3 when it moves synchronously with the sliders 15. At the same time, the connecting frame 16 provides a stable support for the air collecting plate 4 to avoid shaking caused by airflow impact.

[0020] Furthermore, the two air collecting plates 4 are fixedly connected to the surface of the corresponding connecting frame 16. The ends of the two air collecting plates 4 that are far apart are fixedly connected to a telescopic hose 17 for conveying airflow. Each telescopic hose 17 is connected to the interior of the corresponding air collecting plate 4. Specifically, one end of the telescopic hose 17 is connected to an external air source, and the other end extends and retracts flexibly with the movement of the air collecting plate 4, so as to always maintain a stable air supply to the air collecting plate 4 and ensure that the airflow pressure of the first blowing end 6 and the second blowing end 7 remains stable.

[0021] Furthermore, a second cylinder 18 is fixedly connected to the top of the fixed frame 1, and the bottom output end of the second cylinder 18 is fixedly connected to the top of the lifting frame 2. A camera body 19 is fixedly connected to the top of the inner side of the fixed frame 1. Specifically, the extension and retraction of the second cylinder 18 can drive the lifting frame 2 to move up and down as a whole, adjusting the distance between the adjustment component 3 and the fabric surface to adapt to fabrics of different thicknesses; the camera body 19 captures the edge position of the fabric in real time, providing position signal basis for the action of the adjustment component 3.

[0022] Furthermore, a first roller 20 is rotatably connected between the inner walls of both sides of the fixed frame 1, and a second roller 11 is rotatably connected between the inner walls of both sides of the lifting frame 2. The second roller 11 is located on top of the first roller, and both adjusting components 3 are located behind the second roller 11. Specifically, the first roller 20 and the second roller 11 form an upper and lower clamping structure, and the fabric passes through the two to achieve initial flattening and conveying. After being guided by the second roller 11, it enters the working area of ​​the adjusting components 3 to ensure that the fabric is in a taut state during guidance.

[0023] In summary: The second cylinder 18 drives the lifting frame 2 to rise and fall, adjusting the distance between the adjustment component 3 and the fabric to adapt to fabrics of different thicknesses. The camera body 19 captures the edge position of the fabric in real time, providing positional basis for precise alignment. On the lifting frame 2, the motor 14 drives the bidirectional lead screw 13 to rotate, causing the slider 15 to move the two air collecting plates 4 towards or away from each other through the connecting frame 16, flexibly adapting to fabrics of different widths. In the adjustment component 3, the first cylinder 10 drives the rack 9 to slide, and through the meshing of the gear 8, it drives the first blowing end 6 to swing and adjust the angle, forming a gradient airflow with the fixed second blowing end 7. The flexible action of the airflow on the fabric edge achieves alignment, avoiding damage from hard objects. The first roller 20 and the second roller 11 clamp the fabric to complete the initial flattening and conveying, ensuring that the fabric is in a stable tension state when it enters the alignment area. The coordinated operation of all components efficiently solves the fabric deviation problem and ensures stable processing quality.
