This utility model relates to the field of heald frame installation technology for looms, and in particular to a modular heald frame motion
coupling mechanism, including a bracket with both ends bent upwards and a first guide rail installed on both sides. The advantages of this utility model are: by setting up a
drive motor,
crank, first connecting rod, second connecting rod, transmission rod, and actuating rod, the
drive motor is energized and operates. Utilizing the
crank-rocker mechanism, the slider is driven to circulate up and down within the second guide rail, thereby allowing the first and second heald frames to slide relative to each other between the first guide rails, layering the warp yarns. By setting four adjustment components, the length of the mechanism can be adjusted, thereby adjusting the relative movement amplitude of the first and second heald frames. Furthermore, the structure is simple, combining the advantages of quick
assembly and adjustability, while also offering good
maintainability. It enables rapid reconstruction of the motion transmission path and
assembly positioning, facilitating widespread use.
