Rewinding machine with variable speed ratio of unwinding roller and control system of rewinding machine

The invention discloses a rewinding machine with a variable speed ratio of an unwinding roller and a control system of the rewinding machine, and aims to solve the problems that the reduction ratio of a reduction gearbox between an existing motor and the unwinding roller is fixed, so that the existing motor needs to select a special large-range excitation adjustable direct current motor, and the cost of the motor is multiplied. According to the technical scheme, the rewinding machine with the variable speed ratio of the unwinding roller and the control system of the rewinding machine comprise the unwinding roller and a driving motor, a speed reduction box with the variable speed ratio is arranged between the unwinding roller and the driving motor, and the speed reduction box with the variable speed ratio is connected with the unwinding roller and the driving motor through connecting flanges. The speed reduction box with the variable speed ratio comprises a gear shifting mechanism. The gear shifting mechanism
