According to the invention, the edges of the two sides of the face-protecting paper are monitored in real time to timely adjust and simulate the paper width of the face-protecting paper, so that the midpoint is automatically searched on the simulated paper width to realize centering.

Therefore, the bending of the degree of the arc-shaped paper on the face-protecting paper conveyor belt 1 is caused due to the fact that the face-protecting paper conveyor belt 1 is long, the device can still automatically adjust the scoring machine 5 to achieve the purpose that the distances from nicks on two sides to the edge of the face-protecting paper are equal, and when the face-protecting paper is folded and overlapped to a certain degree, due to the fact that the simulation amplitude of the dynamic telescopic cylinder 61 is small, the dynamic telescopic cylinder 61 cannot simulate, the problem of the face-protecting paper outlet system is indirectly judged, at the moment, the control unit 6210 can report error information to an operator, and the operator can conveniently check the face-protecting paper outlet system.

As a preferred scheme of the present invention, the dynamic telescopic cylinder 61 includes two end sliding rings 611, the two end sliding rings 611 are fixedly connected to the two electrically controlled telescopic members 623 in a one-to-one correspondence, an automatic sliding ring 612 is disposed between the two end sliding rings 611, the automatic sliding ring 612 and the two end sliding rings 611 are both sleeved on the sliding support rod 622 in a linearly slidable manner by forming a sliding hole at the center of each of the automatic sliding rings 612 and the two end sliding rings 611, and the scoring machine 5 is movably connected to the automatic sliding ring 612; the sides of two end slip rings 611 facing to automatic slip ring 612 can generate a repulsive force acting on automatic slip ring 612, and when automatic slip ring 612 is located between two end slip rings 611, the repulsive forces of two end slip rings 611 borne by automatic slip ring 612 exactly cancel each other out.

The automatic slip ring 612 is used to perform an automatic centering function.

The principle of centering is mainly realized by the interaction of repulsive forces at two sides, wherein when the end slip ring 611 can generate repulsive forces such as wind power or magnetic force to drive the automatic slip ring 612, the wind power or the magnetic force has a characteristic that although the action strength is attenuated due to the action distance, the two sides of the automatic slip ring 612 are unbalanced in stress when the electric control expansion piece 623 automatically adjusts the two end slip rings 611 and the edge of the mask paper to align with each other, so that the automatic slip ring 612 needs to slide to change the position, and the forces at the two sides are balanced.

As a preferable aspect of the present invention, two first annular magnetic pieces 613 with the same specification are fixedly connected to the sides of the two end sliding rings 611 facing the automatic sliding ring 612, and two second annular magnetic pieces 614 with the same specification are fixedly connected to the two sides of the automatic sliding ring 612; the first annular magnetic sheet 613 and the second annular magnetic sheet 614 have the same size, and a magnetic repulsive force can be generated between the first annular magnetic sheet 613 and the second annular magnetic sheet 614 which are opposite to each other.

By increasing the same-pole repulsive force between the second ring-shaped magnetic sheet 614 and the first ring-shaped magnetic sheet 613, the reason why the magnetic force is selected instead of the wind force is that the strength with which the magnetic force can be actuated is higher.

In a preferred embodiment of the present invention, at least two first guide bars 615 are uniformly and fixedly connected to one of the end slide rings 611, at least two first guide bars 615 are uniformly and fixedly connected to the other end slide ring 611, a first guide groove 617 is provided on the automatic slide ring 612 so as to transversely penetrate the automatic slide ring 612, a second guide groove 618 is provided on the automatic slide ring 612 so as to transversely penetrate the automatic slide ring 612, the first guide bars 615 are linearly and slidably inserted into the first guide groove 617, the second guide bars 616 are linearly and slidably inserted into the second guide groove 618, and the number of the first guide bars 615 and the number of the second guide grooves 618 are the same. The electric control telescopic piece 623 is an electric telescopic cylinder nested on the sliding bearing rod 622.

The second guide slide 616 and the first guide slide 615 are guided to each other to avoid the friction of the automatic sliding ring 612 changing during sliding, and the same number of the first guide slide 615 and the second guide groove 618 is provided to ensure the same friction.

In a preferred embodiment of the present invention, the scoring machine 5 is connected to the automatic sliding ring 612 through a rotary connector 619, and the rotary connector 619 enables the rotary scoring machine 5 to rotate relatively when the automatic sliding ring 612 slides. The rotary connecting piece 619 comprises a first rotary plate 6191 fixedly connected to the automatic sliding ring 612 and a second rotary plate 6192 fixedly connected to the scoring machine 5, the first rotary plate 6191 is rotatably connected with the second rotary plate 6192 through a rotating shaft 6193, and a plurality of reset elastic pieces 6194 are uniformly connected between the first rotary plate 6191 and the second rotary plate 6192; electromagnet blocks 6195 are arranged on two sides of the first rotating plate 6191, a permanent magnet block 6196 is arranged between the two electromagnet blocks 6195, and the permanent magnet block 6196 is fixedly connected with the edge of the second rotating plate 6192.

When the dynamic telescopic cylinder 61 drives the scoring machine 5 to translate, the blade of the scoring machine 5 is arranged along the length direction, so the blade cuts along the length direction, and when the dynamic telescopic cylinder 61 needs to drive the scoring machine 5 to translate, the blade moves transversely, so no blade cuts on the protective paper when the blade moves transversely, and the protective paper is easy to generate a hair piece.

In the present invention, therefore, the scoring machine 5 is driven to deflect to some extent during translation by deflection of the rotary link 619, thereby allowing the blade to make an oblique cut and then reset at the end of translation.

When one of the two electromagnet blocks 6195 is energized, the electromagnet block 6195 generates magnetic action on the permanent magnet block 6196, so that the permanent magnet block 6196 deflects to one side, and the first rotating piece 6191 and the second rotating piece 6192 rotate relatively, and finally reset under the action of the reset elastic piece 6194.
