Description

Technical Field

[0001] The utility model relates to the technical field of chemical fiber production, in particular to a tension regulating device used in chemical fiber production. Background Art

[0002] During the production and processing of chemical fibers, the filamentous fibers are flexible. During the processing, the equipment often switches between start and stop. When the equipment starts, the transmission mechanism runs and the chemical fibers are transmitted; when the equipment stops, the transmission mechanism stops running, but due to the effect of inertia, some shafts will rotate a certain angle before stopping, which causes the chemical fibers to relax. The relaxed chemical fibers not only make the chemical fiber products insufficient in tension, but also easily get entangled in the machinery and equipment after being relaxed for a long time, causing equipment failure and other production accidents. Therefore, it is necessary to design a tensioning mechanism to tension the chemical fibers. However, the tensioning force and tensioning distance of the conventional tensioning mechanisms are not convenient to adjust, making it difficult to adapt to the use of chemical fibers of different materials. Therefore, we propose a tension adjustment device for chemical fiber production to solve this problem. Utility Model Content
