Abstract
Description
Technical Field
[0001] This utility model relates to the field of warp stop frame technology, specifically a warp stop frame support arm for a loom. Background Technology
[0002] As the core component of the warp breakage automatic stop device of the loom, the warp stop bracket arm mainly functions to support and fix the warp stop plate (thin steel plate) with the yarn threading hole to ensure the stability of the warp tension and to trigger the stop mechanism in time when the yarn breaks.
[0003] Traditional loom stop frame supports generally employ a fixed structure, primarily consisting of a mounting plate and fixed supports, which are directly fixed to the loom frame via welding or bolts. This design limits the flexibility of adjusting the length and position of the supports. Although some improved designs attempt to achieve length adjustment through recessed adjustment of the supports, these still rely on manual sliding and simple positioning hole locking, resulting in limited adjustment range and insufficient precision, making it difficult to meet practical usage requirements. Therefore, we propose a new type of loom stop frame support. Utility Model Content
