[0048] When the roller frame 514 moves away from the middle pressing plate 3, the plug-in plate 702 is continuously pulled outwards, when the roller frame 514 moves to the edge of the binding, the limiting roller 607 moves away from the side plate 601, so that the first conductive rod 609 on the movable plate 604 is in contact with the conductive slide strip 611, and the conductive slide strip 611 is electrically connected with the external circuit of the electromagnet 7048, so that the external circuit of the electromagnet 7048 is connected, and after the electromagnet 7048 is powered on, the magnetic block 7047 is repelled, the auxiliary pressing plate 7045 is pushed towards the binding, so that a plurality of auxiliary pressing plates 7045 are pressed tightly under the repulsive force of the electromagnet 7048, the pressing effect of the binding is improved, and at the same time, when the fixed column 7041 on the plug-in plate 702 moves out of the plug-in groove 701, the moving block 7052 moves upwards under the elastic force of the fourth spring 7055, so that the second conductive rod 7056 is in contact with the second contact 7057, the independent parallel circuit connected with the electromagnet 7048 is connected, and only the electromagnet 7048 located outside the plug-in groove 701 can be connected, so that the electromagnet 7048 in the plug-in groove 701 is not connected, the auxiliary pressing plate 7045 is pressed tightly with the inner wall of the plug-in groove 701, and the moving stability of the pressing roller 515 is affected;

[0049] After the processing is completed, the second power switch connected with the motor 508 is turned on, so that the motor 508 is connected with the reverse current, the moving plate 503 is moved back, in the moving back process, the limiting roller 607 is pushed back, so that the first conductive rod 609 is separated from the conductive slide strip 611, the electromagnet 7048 is all powered off, the auxiliary pressing plate 7045 is moved back, and the plug-in plate 702 is moved back to the inside of the plug-in groove 701.
