Description

Technical Field

[0001] This utility model relates to the field of weft straightening machine technology, specifically a weft straightening machine for adjusting the tilt angle of a canvas. Background Technology

[0002] Fabric is generally made of warp and weft yarns that are perpendicular to each other and interwoven at a 90-degree angle. The longitudinal yarns are called warp yarns, and the transverse yarns are called weft yarns. During the transportation process, the fabric is transported by multiple conveyor rollers and is in a traction state. Due to the influence of mechanical movement and production operations, the weft yarns often become skewed or bent, which affects the production quality of the fabric. Usually, it is necessary to straighten the skewed or bent weft yarns.

[0003] Patent document CN216551257U discloses an easily adjustable weft straightening structure, relating to the technical field of textile processing. It includes a frame, a horizontally mounted weft straightening rod, and a weft straightening frame mounted on the weft straightening rod. Both ends of the weft straightening rod are rotatably connected to the frame. One end of the weft straightening rod is equipped with an angle adjustment mechanism for adjusting the angle between the weft straightening frame and the fabric. The weft straightening frame abuts against the fabric and is used to straighten the weft yarns at locations where they are skewed. A sliding assembly is provided between the weft straightening frame and the weft straightening rod, allowing the weft straightening frame to slide along the axial direction of the weft straightening rod. The angle adjustment mechanism drives the weft straightening rod to rotate along its axial direction, allowing the operator to adjust the angle of the weft straightening frame according to the degree of weft yarn skew. The weft straightening frame is slidably mounted on the weft straightening rod via the sliding assembly, enabling it to straighten the weft yarns at different positions on the fabric, thus improving the production quality of the fabric.

[0004] Although the angle adjustment mechanism in the aforementioned application document can drive the weft straightening rod to rotate along its axial direction so that the operator can adjust the angle of the weft straightening frame according to the degree of weft yarn skew, it requires the operator to manually reach into the machine to adjust the position of the weft straightening rod, making the adjustment inconvenient.

[0005] Therefore, a weft straightening machine for adjusting the tilt angle of the canvas is proposed to solve the problems mentioned above. Utility Model Content
