In addition, the third cylinder can be set to extend out of a preset length according to a corresponding instruction of the control signal so as to cut off the current paper; the control circuit is configured to output a release command to the hold-down mechanism and a retract command to the shut-off mechanism 8 when the shut-off mechanism 8 completes the shut-off operation. The control circuit outputs a release instruction to the pressing mechanism, namely controls a corresponding electromagnetic valve of a circuit where a second cylinder connected with the pressing mechanism is located to act so as to realize the piston retraction action of the second cylinder; the control circuit outputs a retraction command to the cut-off mechanism 8, that is, controls the corresponding solenoid valve of the line in which the third cylinder connected to the cut-off mechanism 8 is located to move, so as to realize the retraction movement of the piston of the third cylinder.
In the specific operation, the initial state of the cutting wire is positioned below the working paper; when the cutting action is needed, the cutting wires extend out and extend to the lower surface of the current working paper. As shown in fig. 3, the cutting wire is provided with a cutting edge, and the cutting edge can cut the working paper 11 in a tensioned state by the action of the paper surface tension when the cutting edge touches the lower surface of the paper; after the cutting operation is finished, the cutting wire returns to the initial position; meanwhile, the paper head 12 of the new paper roll to be received above the current working paper 11 is in a release state, namely a non-tensioning state, and the cutting wire cannot cut the new paper to be received above in the cutting process of the current working paper. The cutting mechanism 8 provided by the application can be used for ingeniously utilizing the characteristic that the paper head of the new paper roll to be received is in a release state and the paper of the current working paper roll is in a tension state, and cutting operation of cutting wires is implemented. According to the existing cutting structure, each cutting operation needs to be independently arranged between new paper to be received and current working paper so as to complete the cutting operation, and the cutting mechanism needs to be adjusted to an area between the two pieces of paper when each cutting operation is carried out. However, the structure provided by the application can realize the cutting of the paper of the working paper roll from the lower part and does not cut the new paper to be received from the upper part based on the performance characteristic that the paper head of the new paper roll to be received is in a release state; based on this, the cutting structure that this application proposed can set up in the below of the current work paper, need not set up between two papers, and need not the independent setting of every turn.

It should be noted that, in the process of paper receiving operation, the tightening belts 9 are not temporarily installed on two sides of the new paper roll to be received, and are intended to keep the new paper roll to be received in a release state, so as to effectively ensure accurate cutting operation of the cutting wire during subsequent cutting operation; after the paper receiving operation is completed, namely the cutting wire cuts the current working paper roll, the new paper roll to be received becomes a new working paper roll at the moment, and when the paper is conveyed to a subsequent production line, the tightening belts 9 can be installed on two sides of the paper roll to provide friction force required in the subsequent normal unreeling process.
In the specific operation, the unwinding mechanism is a free unwinding mechanism and belongs to a tension-free controlled unwinding process; the paper roll can be effectively ensured to be in a tensioning state through the friction force between the tightening belt 9 and the paper roll; at the same time, the friction between the arc-shaped contacts will decrease as the radius of the roll decreases, based on the elastic properties of the tightening band 9; i.e. the friction experienced by the initial state of the roll is greatest and then decreases slowly, keeping the paper in tension all the time, which enables a technical effect similar to that of the tension control of the prior art to be obtained.
