Description

Technical Field

[0001] The utility model relates to the technical field of textile production technology, in particular to a retreat-stopping intermediate supporting device for a heald frame. Background Art

[0002] The heald frame, also known as the heald frame, plays a key role in textile engineering. It consists of a frame connected by upper and lower beams and left and right side rails, equipped with a heald rod and drive components. When the flat healds are installed on the heald frame, they gather the warp yarns that have been passed through the flat healds into a single unit. The movement of the heald lifting mechanism on the loom causes the heald frame to move up and down according to the shedding mechanism, shedding the warp yarns in layers, allowing the weft yarns to weave through them and interweave into fabrics of varying patterns.

[0003] During use, traditional heald frames only support the upper and lower beams on both sides, resulting in an unstable connection in the middle position. This makes the heald frames unstable and easily damaged when moving up and down at high speed. In addition, in traditional devices, the connections between the heald frames are unstable, and displacement between the heald frames may occur, increasing the failure rate. In order to reduce the failure rate of the heald frames during operation and improve the stability of the connections between the heald frames, we propose a stop-retraction intermediate support device for the heald frames.
