Description
Technical Field
[0001] This utility model relates to the field of loom equipment technology, specifically to a connection device for a loom box and a U-shaped beam. Background Technology
[0002] A loom is a textile machine used to weave or spin yarn or other thin materials into fabrics. Based on its power source, looms can be classified as water-powered looms, pneumatic looms, and electric looms. The main structure of a loom includes a yarn feeding device, a yarn guiding device, loom drums, a shuttle system, and the mechanisms that drive the various components of the loom. Among these, the shuttle system is a crucial part of the loom, consisting of the shuttle body, shuttle case, and shuttle beam, responsible for loading and conveying the weft yarn.
[0003] In a loom, the U-beam primarily serves a supporting and transmission function. It supports other components of the loom, such as the warp and weft beams, ensuring stable operation. Simultaneously, the U-beam, through its structural characteristics, transmits power to all parts of the loom, enabling fabric weaving. The heald frame is a crucial component in textile machinery. Its main function is to move the warp yarns up and down through the heald frame's movement, thus achieving warp and weft yarn interlacing. The design and structure of the heald frame directly affect the loom's operating efficiency and fabric quality.
[0004] Chinese Patent Application No. 202323344905.4 discloses a lifting arm bearing structure for a cam opening device. The disclosed lifting arm bearing structure includes a U-shaped beam and a cam box. A swing arm shaft is provided inside the cam box. Swing arms are connected to both ends of the swing arm shaft. A short connecting rod is hinged to the swing arm. The short connecting rod is connected to the lifting arm at one end relative to the swing arm. The lifting arm is sleeved on the lifting arm shaft. Triangular brackets are connected to the two side walls of the U-shaped beam by first fixing bolts. One end of the triangular bracket is a vertical mounting part fixedly connected to the cam box body, and the other end is provided with a bearing for fixing the lifting arm shaft. The vertical mounting part is fixedly connected to the cam box body by several second fixing bolts. An arc-shaped cover plate is provided on the bearing plate. The lifting arm shaft is located between the bearing plate and the arc-shaped cover plate, and the arc-shaped cover plate is fixedly connected to the bearing plate by a third fixing bolt. Chinese Patent Application No. 202210418315.2 discloses an upper-mounted loom shedding device. The disclosed loom shedding device includes: a frame component; a housing assembly installed at one end of the frame component; a heddle shedding component installed inside the frame component, and the heddle shedding component cooperates with the housing; the housing assembly includes: a cam housing, a shaft mounting seat, a cam assembly, a swing arm assembly, and a transmission assembly.
[0005] In the aforementioned prior art, the housing and U-shaped beam are connected and fixed by a triangular bracket, and the heald arm shaft is connected to the shaft seat of the triangular bracket. When the loom is running, the U-shaped beam vibrates significantly, and the triangular bracket will vibrate synchronously with the U-shaped beam. This can easily reduce the connection strength between the triangular bracket, the U-shaped beam, and the housing, further increasing the vibration amplitude of the U-shaped beam, thus affecting the weaving precision of the loom and consequently the quality of the fabric. At the same time, the triangular bracket does not provide sufficient support for the heald arm shaft, which can easily cause the heald arm shaft to wobble. Utility Model Content
