Description

Technical Field

[0001] The utility model relates to the technical field of chenille machines, in particular to a wire breakage monitoring device for chenille machines. Background Art

[0002] Chenille yarn, also known as chenille, is a new type of fancy yarn. It is made of two strands of yarn as the core, and the feather yarn is sandwiched in the middle by twisting. Chenille decorative products can be made into sofa covers, bedspreads, bed blankets, table blankets, carpets, wall decorations, curtains and other indoor decorative accessories. It is made by chenille machines. During its use, one person needs to look after several machines, and thus it is impossible to find the broken thread problem in time;

[0003] The existing patent discloses a thread breakage monitoring device for a chenille machine (publication number: CN212771183U). When the chenille yarn breaks or becomes abnormally loose, the guide wheel loses pressure and rises under the action of a spring, triggering a pressure-touch switch and lighting a warning light to realize alarm processing. However, the elastic force of the spring decreases during long-term compression, and then when the yarn breaks or becomes abnormally loose, the thread cannot be driven to rise in time, thereby failing to trigger the pressure-touch switch in time and thus failing to alarm in time. Therefore, the utility model proposes a thread breakage monitoring device for a chenille machine. Utility Model Content
