Anti-loosening accurate-metering adhesive tape rewinding device

The utility model discloses an anti-loosening accurate-metering adhesive tape rewinding device which comprises a rack, a driving device, a transmission belt, a rewinding roller, an unwinding roller, a metering wheel and an adhesive tape roll, and the unwinding roller is sleeved with the adhesive tape roll. The driving device drives the rewinding roller to rotate through the transmission belt, the adhesive tape unwound by the adhesive tape roll sequentially bypasses the metering wheel and the rewinding roller, the adhesive tape drives the metering wheel to rotate, and the length of the adhesive tape on the rewinding roller can be calculated according to the number of turns of rotation of the metering wheel. The rotating axes of the metering wheel, the unwinding roller and the rewinding roller are arranged in parallel; the edge of the metering wheel is connected with an inductive head, the rack is connected with a position sensor and a counter, and when the inductive head is close to the side of the position se
