Description

Technical Field

[0001] The utility model belongs to the technical field of textiles, and in particular relates to a heald frame connecting device for a loom. Background Art

[0002] The heald frame is an important component of the loom. It is a frame with heald rods connected by upper and lower beams and left and right side rails. After the flat healds are arranged on the heald frame, the warp yarns inserted into the flat healds are gathered into one. With the movement of the heald lifting mechanism of the loom, the heald frame moves up and down according to the program of the opening device, so that the warp yarns are opened in layers, allowing the weft yarns to shuttle through the warp yarns and be interwoven into fabrics with different patterns.

[0003] The prior art scheme is as follows: Announcement No.: CN211947430U The utility model discloses a heald frame connecting device, which belongs to the technical field of textile machinery, including a loom, a heald lifting mechanism is installed on the top of the loom, and there are two heald lifting mechanisms. The loom is movably connected with a fixed clamp through the heald lifting mechanism, and a spring is welded at the bottom of the fixed clamp. The fixed clamp is movably connected with a movable clamp through the spring. The movable clamp is pulled to place the heald frame between the fixed clamp and the movable clamp, and the movable clamp is released. Under the action of the spring elastic force, the movable clamp and the fixed clamp are close to each other, squeezed and fixed the position of the heald frame, and then the heald frame is connected to the loom together. The disassembly is simple and the replacement is easy. When the heald lifting mechanism drives the heald frame to move up and down through the fixed clamp and the movable clamp, the moving range of the movable clamp can be limited under the action of the limit rod, so as to avoid the displacement of the movable clamp and improve the stability of the fixed clamp and the movable clamp during the movement, thereby improving the efficiency and quality of the heald threading.
