Description

Technical Field

[0001] The utility model relates to the technical field of water jet looms, in particular to a thread pressing device for a water jet loom. Background Art

[0002] A water jet loom is a shuttleless loom characterized by high friction and low diffusion of the weft yarn, making it particularly suitable for weaving smooth-surfaced fabrics using filament weft insertion, such as synthetic fibers and glass fibers. Furthermore, water jet looms consume less energy and produce less noise when injecting the weft yarn, resulting in high efficiency and low costs. The thread-holding device plays a crucial role in the weaving process. It controls the weft yarn tension, ensuring it is properly clamped as it enters the shed and exits. The performance of the thread-holding device directly impacts fabric quality, including smoothness, texture definition, and production efficiency.

[0003] Traditional water jet loom thread pressing devices usually rely on manual adjustment to control the tension of the yarn. This method is time-consuming during the adjustment process and is not conducive to quickly responding to changing weaving conditions. The low efficiency and lack of flexibility of this operation limit the rapid adaptability of the weaving process, which may affect the overall production efficiency and fabric quality. In addition, most traditional water jet loom thread pressing devices are designed with a single slide, which may cause faster wear because the movement and positioning of all yarns rely on this single path. This design makes the slide bear greater pressure during the weaving process, requiring more frequent maintenance and replacement, which correspondingly increases the operation and maintenance costs of the loom.

[0004] Therefore, those skilled in the art provide a thread pressing device for a water jet loom to solve the problems raised in the above background technology. Utility Model Content

[0008] The upper and lower parts of the front end outer wall of the main body plate close to the first hinge are both fixedly connected with the second hinge.

[0009] Through the above technical solution, the electric telescopic rod is activated to move inward and outward directions respectively, and the electric telescopic rod can accurately adjust the position of the fixed plate, thereby directly controlling the tension of the yarn. This precise control helps to ensure that the yarn maintains a constant tension during the weaving process, so that the tightness of the yarn can be quickly adjusted to meet different weaving requirements. In addition, the design of the electric telescopic rod enables the thread pressing device to adapt to various weaving conditions and yarn materials, thereby improving the versatility and flexibility of the equipment.

[0014] Furthermore, the inner walls of the first hinged parts are hingedly connected to a rotating plate, and the inner walls of the second hinged parts are hingedly connected to an electric telescopic rod;

[0015] Through the above technical solution, the hinged design allows the rotating plate and the electric telescopic rod to move freely within a certain range, so that the thread pressing device can adapt to different weaving requirements, thereby enhancing the flexibility and adaptability of the device.

[0016] Furthermore, the middle portion of the rear end of the outer wall of the rotating plate is fixedly connected to a third hinged member, and the inner wall of the third hinged member is hingedly connected to the output end of the electric telescopic rod;

[0017] With the above technical solution, the output end of the electric telescopic rod is hingedly connected to the third hinge member so that the electric telescopic rod drives the rotating plate to move, thereby achieving precise control of the position of the rotating plate.

[0018] Furthermore, one end of the outer wall of the rotating plate away from the first hinge is fixedly connected to a fixed plate, and a plurality of second sliding grooves are formed on the outer wall of the outer wall of the fixed plate away from the first hinge;

[0019] Through the above technical solution, a fixed guiding path is provided for the yarn through the second slide groove, ensuring that the yarn can move along a predetermined trajectory when passing through the fixed plate, which helps to accurately position and control the yarn.

[0020] Furthermore, a plurality of power supply slots are provided on the lower portion of one side of the outer wall of the main body plate;
