The application belongs to the field of
metal strip winding, in particular to a
metal thin strip longitudinal shearing tension adjusting anti-loosening device, which comprises a
caisson and driving tables arranged on the
caisson and close to both sides, the
metal strip after longitudinal shearing passes through the two driving tables, the top of the
caisson is provided with an opening, the inner side of the caisson is provided with an adjusting groove for adjusting the tension of the metal strip, the middle top of the caisson is provided with a
wind power module, the
wind power module comprises a fan for generating
wind power and an air exhaust device for adjusting the direction of wind power; through such a setting, not only the influence of the tension after longitudinal shearing on the metal strip is self-adaptively adjusted by using the gravity of the metal strip itself, but also for the
thin metal strip with low quality, the wind power acting from top to bottom is used to reduce the
vibration amplitude of the metal strip and improve the interval between adjacent
metal strips, so that the safe and stable transportation process of the
metal strips without collision under high-speed transportation is ensured, the work efficiency is improved, and the
operation safety is also ensured.
