The electromagnetic preheating roller 2 is internally provided with an induction coil, the heating principle is that the induction coil generates an alternating magnetic field in the electromagnetic preheating roller 2 through alternating current, the electromagnetic preheating roller 2 body is made of metal materials with magnetic conduction characteristics, magnetic lines of force of the alternating magnetic field pass through the electromagnetic preheating roller 2 from one magnetic pole to the other magnetic pole to form a loop, the magnetic lines of force can cut the electromagnetic preheating roller 2, induced electromotive force is generated in the electromagnetic preheating roller 2, and therefore eddy current is generated, and the electromagnetic preheating roller 2 generates heat due to the eddy current.

Wherein, a damping is arranged between the swinging cylinder 13 and the connecting shaft 14, the connecting shaft 14 is provided with a counter weight 6 through a jacket 11, the front-end base paper enters the shaking device 4 conveyed to the lower end after being preheated by the electromagnetic preheating roller 2, and the counter weight 6 is used for balancing and adjusting the gravity center because the tension of the preheated base paper and the non-preheated base paper is different, the hardness and the extensibility of the base papers with different preheating times are also different, so that the opening angle changes under the tension change when the base papers are conveyed by the floating roller 5, the damping is used for balancing the change, the edge curling of the conveyed base papers caused by the too fast opening angle change is prevented, and the counter weight 6 is used for balancing and adjusting the gravity center.

The rear end of the oscillating cylinder 13 is integrated with an angle sensor at the connecting shaft 14, the angle sensor can adopt a capacitive inclination angle sensor, when the connecting shaft 14 deflects, the capacitance resistance changes, so that the output voltage and the current change, and the oscillating cylinder 13 is controlled to automatically adjust and oscillate according to the output signals of the voltage and the current.
