The specific process of step 3 is: the printing process is divided into two paths:

The first route, the floating roller position detection linear potentiometer detects the position information of the synchronous floating roller in real time, and transmits the position information to the servo control system. The servo control system compares the received position information with the set position information to obtain the position deviation. If the position deviation is -10mm<θ<10mm, the running speeds of the synchronous control unit traction roller, creasing roller and punching roller remain unchanged. If the position deviation θ>10mm, the servo control system controls the speeds of the synchronous traction motor, creasing roller motor and creasing roller motor by adjusting the electronic gear ratios of the synchronous traction driver, creasing roller driver and punching roller driver, respectively, thereby controlling the speed of the synchronous control unit traction roller, creasing roller and punching roller to be adjusted forward; if the position deviation θ<-10mm, the speeds of the synchronous control unit traction roller, creasing roller and punching roller are adjusted in the opposite direction;

The creasing roller motor and the creasing roller motor adjust the phase of the creasing roller and the punching roller in the positive direction. If the position deviation δ<-0.02mm, the phase of the creasing roller and the punching roller is adjusted in the negative direction. If the average value of the synchronization deviation is -0.1mm<η<0.1mm, the speed of the traction roller of the synchronous control unit remains unchanged. If the average value of the synchronization deviation η>0.1mm, the servo control system controls the speed of the synchronous traction motor by adjusting the electronic gear ratio of the synchronous traction drive, thereby controlling the speed of the traction roller of the synchronous control unit to be adjusted in the positive direction.
