The utility model discloses a constant tension control system for surface protection paper of a forming station, which comprises a paper unwinding machine and a forming platform, and is characterized by further comprising a paper pulling machine arranged between the paper unwinding machine and the forming platform, the paper pulling machine comprises a driving roller, a driven roller and a motor, a gap for surface protecting paper to pass through is formed between the driving roller and the driven roller, the thickness of the gap is smaller than that of the surface protecting paper, the rotating direction of the driving roller is consistent with the moving direction of the surface protecting paper, the motor is used for driving the driving roller, and the rotating speed of the motor is adjustable. Therefore, the tension of the surface protecting paper can be adjusted by adjusting the rotating speed of the motor, so that the tension of the surface protecting paper is always kept at the preset tension value.
