Further, as shown in fig. 4, when the second conductive strip 415 is energized, the electromagnet 413 which is adjacent to the first conductive strip 414 counterclockwise is energized to generate magnetism, the permanent magnet 412 attracts the electromagnet 413, and the driving disk 404 is driven to rotate clockwise by 90 degrees, thereby driving the cut hard base paper to rotate 90 degrees, at this time, the first conductive strip 414 corresponding to the electromagnet 413 corresponds to the second conductive strip 415, the electromagnet 413 which is counterclockwise adjacent to the first conductive strip 414 is energized to generate magnetism, and the drive disc 404 rotates 90 degrees again, so that the hard base paper rotates 90 degrees again, the above steps are repeated to make the driving disk 404 intermittently rotate at 90 degrees, so that the cut hard base paper can be absorbed and moved to a collecting vehicle, and the positions of the hard base paper right below are consistent every time, so that the hard base paper is kept orderly when being collected, and the later printing is facilitated.

It should be noted that a rubber pad is disposed between an inner wall of the driving slot 403 away from the second conductive strip 415 and a side wall of the driving disc 404 away from the plurality of first conductive strips 414, which increases insulation when the device is used and increases stability when the driving disc 404 does not rotate.

Be equipped with on board 1 and carry out moving mechanism 5 that removes to the body paper, moving mechanism 5 is including seting up at the recess 501 of board 1 upper end, recess 501 inner wall rotates and is connected with lead screw 502, lead screw 502 lateral wall threaded connection has slider 503, slider 503 upper end is through third pole 505 fixedly connected with movable plate 506, two spouts 507 have been seted up to movable plate 506 inner wall, two spout 507 inner walls have clamping bar 509 through conductive spring 508 elastic connection, clamping bar 509 is the T type form, drive lead screw 502 pivoted second motor 504 is installed to board 1 lateral wall, conductive spring 508 passes through diode I and second motor 504 coupling connection.

It should be noted that the diode I only allows reverse current to pass through, that is, when the second motor 504 is energized with reverse current to make the lead screw 502 rotate in the reverse direction, the conductive spring 508 is energized to contract at this time, and then the two clamping rods 509 are away from each other, and then when the slider 503 drives the moving plate 506 to move towards the direction of the hard base paper, the hard base paper can be located between the two clamping rods 509 at this time, when the second motor 504 is energized with forward current to make the lead screw 502 rotate in the forward direction, the conductive spring 508 is deenergized to extend at this time, and then the two clamping rods 509 are close to each other to clamp the hard base paper, and then the slider 503 moves to drive the hard base paper to move, and then the hard base paper is conveyed to be cut at a fixed length, so that wrinkles are prevented from being accumulated together after the hard base paper is conveyed, and the cutting quality and appearance of the hard base paper are affected.

The second conductive strip 415 is coupled to the anode of the second motor 504 through a diode II, and the plurality of electromagnets 413 are coupled to the cathode of the second motor 504.

It should be noted that the diode II only allows a reverse current to pass through, that is, when the second motor 504 is energized with a reverse current, the circuit between the second conductive strip 415, the first conductive strip 414 and the electromagnet 413 counterclockwise adjacent to the first conductive strip 414 is conducted, and then the permanent magnet 412 attracts the electromagnet 413, so as to drive the driving disc 404 to rotate 90 ° clockwise, and at this time, the hard base paper is located between the two clamping bars 509, that is, when the second motor 504 is rotated in the reverse direction to move the moving plate 506 to the hard base paper, at this time, the driving disc 404 rotates just 90 °, when the second motor 504 is energized with a forward current, the circuit on the electromagnet 413 is disconnected, and the driving disc 404 remains stationary, so that one of the adsorption plates 407 is located right above to adsorb the hard base paper, so that when the second motor 504 periodically rotates in the forward direction and rotates in the reverse direction to convey the hard base paper, the driving disc 404 may intermittently rotate 90 ° at this time, and then sequentially convey the cut hard base paper.

Two second boards 6 of 2 lower extremes fixedly connected with of first board, two flattening rollers 7 are installed through the pivot to 6 lateral walls of two second boards, can carry out the flattening to the stereoplasm body paper in the transportation process, improve its cutting quality, and there is a raw paper section of thick bamboo 8 board 1 upper end through the support mounting.

In the invention, one end of the hard base paper on the base paper cylinder 8 passes through the two leveling rollers 7, then the second motor 504 is driven to rotate reversely, at the moment, the two conductive springs 508 are electrified and contracted, and then the two clamping rods 509 are far away from each other, so that when the lead screw 502 rotates reversely to drive the sliding block 503 to slide, at the moment, the moving plate 506 can move to the outer side of the hard base paper, then the second motor 504 is driven to rotate forwardly, at the moment, the two conductive springs 508 are electrified and contracted, and then the two clamping rods 509 approach each other to clamp the hard base paper, at the moment, the lead screw 502 rotates forwardly to move the hard base paper to the adsorption plate 407, then the first motor 302 is driven to rotate, and the position of the cutting knife 303 is operated through the control console 301 to cut the hard base paper;

when the hard base paper moves to the adsorption plate 407, because the air suction pipe 409 is connected with an external air suction pump at the moment, negative pressure is generated on the adsorption plate 407 at the moment, and then the adsorption plate 407 tightly adsorbs the hard base paper through the adsorption holes 408, so that the stability of the hard base paper during cutting is improved, and after the cutting is finished, the two electric push rods 401 are adjusted to extend, and then the adsorption plate 407 drives the cut hard base paper to move downwards;

then, the second motor 504 is continuously driven to rotate reversely, so that the moving plate 506 can move towards the direction close to the hard base paper again, and the hard base paper can be continuously conveyed and cut;

and when the second motor 504 rotates in the reverse direction, the circuit is conducted between the second conductive strip 415, the first conductive strip 414 and the electromagnet 413 adjacent to the first conductive strip 414 counterclockwise, the permanent magnet 412 attracts the electromagnet 413, and the driving disk 404 is driven to rotate clockwise by 90 degrees, thereby driving the cut hard base paper to rotate, and the absorption plate 407 which is anticlockwise adjacent to the absorption plate 407 rotates 90 degrees clockwise to the right upper side, and at this time, the hard base paper is again positioned between the moving plates 506, and then the two electric push rods 401 are adjusted to contract, and the movable frame 402 moves upwards to make the lower surface of the adsorption plate 407 flush with the lower surface of the hard base paper, and then the second motor 504 is driven to rotate in the forward direction, so that the hard base paper is conveyed to the adsorption plate 407 again to be cut, after the hard base paper is cut, the operations are repeated, and the driving disc 404 can be driven to intermittently rotate 90 degrees clockwise while the hard base paper is conveyed and cut;

when the driving disc 404 intermittently rotates clockwise by 90 degrees so that the hard base paper on the adsorption plate 407 is located right below, the connecting pipe 410 corresponding to the hard base paper is separated from the through groove 411, so that the air is not sucked in the connecting pipe 410, and the hard base paper can fall onto the collecting vehicle located below the movable frame 402 under the action of gravity, so that the hard base paper is placed and collected in order.
