After the base material is manufactured, in order to facilitate its inspection, slitting or combining with other materials, the base material is usually rolled and rewound through a rewinding machine. For its winding tension, the winding mechanism must be separately controlled for its winding tension; however, since the tension of the substrate is continuous during the winding and unwinding process of the rewinder, it is often caused by the continuous tension. In this state, when different winding tensions are applied, it often causes the substrate of the unwinding device to shrink, which will cause the winding of the substrate on the unwinding device to shrink, resulting in deformation and extrusion.

1. Through the setting of the blocking device in this creation, in the normal state, the conveying wheel, the braking wheel and the rewinding wheel are in a state of equal tension to convey the material correspondingly, and when the tension needs to be blocked, When the tension is discontinuous, the braking device can be set to correspondingly brake on the braking wheel according to the first tension value, so that the tension between the conveying wheel and the braking wheel, as well as the tension between the braking wheel and the winding wheel, will be affected by the braking wheel. Therefore, the tension between the two of them is discontinuous, so as to achieve the effect of tension blocking; through this, the tension between the braking wheel and the braking wheel can be adjusted to achieve the tension between the conveying wheel and the braking wheel.

If the tension of material 2 needs to be adjusted according to the requirements of inspection, slitting, subsequent processing, and compounding with other substrates, the tension of material 2 can be adjusted as shown in Figure 2. In a blocking state, the brake device 31 is correspondingly braked on the brake wheel 4 according to the first tension value; this will cause the tension of the material 2 at one end of the take-up wheel 3 to be braked by the brake wheel 4, so that the The tension T1 between the braking wheel 4 and the take-up wheel 3 is not continuous with the tension T2 between the braking wheel 4 and the conveying wheel 1 and is blocked.
