Abstract
The utility model provides a tension detecting apparatus comprising a shaft core, a roller, and a pedestal. One end of the shaft core is inserted into a fixed slot on the pedestal. The two ends of the roller are both equipped with bearings. The two ends of the shaft core are mutually pivoted on the bearings through detecting modules. Because the two ends of the shaft core are mutually pivoted on the bearings through detecting modules, the position of belt material placed on the roller does not affect detection precision any more. Therefore, the detection precision is increased.
