At this time, the new paper roll is replaced as a new work paper roll, and when the feeding to the subsequent production line is started, the tightening belt 9 can be installed on both sides thereof. To provide the friction required for subsequent normal unwinding.

In the specific operation, the unwinding mechanism is set as a free unwinding mechanism, and belongs to a tension-free control unwinding process; by tightening the friction between the belt 9 and the paper roll, the paper roll can be effectively ensured to be in a tension state; To tighten the elastic properties of the belt 9, the friction between the arcuate contacts decreases as the radius of the paper roll decreases; that is, the initial state of the paper roll is subject to the greatest friction, then slowly decreases, and the paper is always kept. Being in a tensioned state, it is possible to obtain a technical effect similar to the tension control in the prior art.

Optionally, in order to further improve the adaptability of the tightening strap, a sliding base may be disposed between the connecting rod or the connecting hole and the chain swinging mechanism, and the sliding base is configured to adjust the distance between the adjacent two connecting rods or the connecting holes The sliding direction of the sliding base is perpendicular to the central axis of the paper roll. The sliding base may be configured as a sliding structure such as a sliding groove type or a sliding block type, so as to achieve position adjustment. By adjusting the position of the sliding base provided by the connecting rod or the connecting hole, the distance between two adjacent mounting points can be realized correspondingly, and the size of the curved contact surface can be indirectly realized, thereby adjusting the friction force. It should be noted that the above-mentioned slider position adjustment is mostly used for the initial state of the paper roll, and the paper rolls of different specifications may have outer diameters of different sizes; therefore, the tightening belt is required to have a position adjustment function to realize paper of different outer diameters. The tension of the roll is left and right; when the paper roll is in a stable unwinding state, the above slider adjustment operation is not required.
