The invention provides a novel aluminum-plastic composite belt longitudinal wrapping and releasing tension constant device, which comprises a belt releasing frame, a pneumatic brake installed at an aluminum-plastic composite belt releasing shaft of the belt releasing frame, and a straightening roller assembly arranged on a straightening roller mounting frame and provided with a tension sensor. Thepneumatic brake and the tension sensor are connected to a controller. The brake and the belt releasing frame of the releasing tension constant device are integrated as a whole. After the belt is released by the belt releasing frame, the belt is straightened by the straightening roller. Meanwhile, the tension borne by the belt is fed back to a PLC integrated control system through the tension sensor. The PLC integrated control system compares the tension fed back by the tension sensor with a preset tension and then sends an adjusting signal to a pneumatic proportional control valve. The pneumatic proportional control valve uses compressed air as a power source and uses an air cylinder as an actuator to achieve proportional adjustment of a brake for braking or loosening. Therefore, the constant tension is achieved.
