S1. Coarse adjustment: Turn on the hydraulic pump and control the output end of the hydraulic cylinder to move downward to push the screw to move downward. Since the relative position of the screw and the rotating shaft is fixed, and the two ends of the rotating shaft slide relatively on the side plate, so , that is, the overall vertical and horizontal displacement of the cutter can be controlled by the hydraulic pump, and the synchronization of both ends of the cutter can be adjusted through the diverter and flow valve 21;

S2. Fine adjustment: Control the screw motors on both sides of the side plate respectively. The screw motor drives the screw to rotate, and the screw drives the mediation gear to rotate. Here, the meshing of the screw and the mediation gear is similar to the principle of the indexing plate. It should be noted that the axial directions of the screw rod and the mediating gear are not necessarily parallel to each other, but can be perpendicular to each other in the axial direction like the worm in the indexing plate and the indexing plate body, so as to minimize the rotation between the two Proportion; then the mediating gear and the small intermediate wheel rotate coaxially, the small intermediate wheel drives the large intermediate wheel to rotate, the large intermediate wheel drives the driven wheel to rotate, the driven wheel and the screw rotate coaxially, and the screw and the nut seat rotate mutually to realize the position of the cutter fine-tuning;

Due to the multi-level deceleration between the screw rod and the intermediate gear, as well as between the small intermediate wheel, the large intermediate wheel, and the driven wheel, the fine-tuning accuracy is high; and because of the existence of the coarse-adjustment unit, the two can be adjusted accurately The relative position of the cutting knife, the adjustment time is short and convenient, and will not produce more waste.

Axially parallel to each other; this kind of teeth can play two roles, one is to drive and connect the large intermediate wheel 22 and the driven wheel 27, and the other is to play a guiding role. The teeth of the driven wheel are on the teeth of the large intermediate wheel. The teeth move relative to each other along the vertical direction, and then precisely locate. Correspondingly, the length of the large middle wheel is greater than the stroke of the screw rod along the vertical direction.

In the fully automatic die-cutting machine of the present utility model, in order to prevent the position of the cutter from changing due to long-term vibration when the cutter rotates, both sides of the base 10 are also provided with a positioning oil cylinder 28, and the output end of the positioning oil cylinder 28 is arranged at the bottom of the screw rod 18. And relatively move relative to the bottom of the screw rod 18;
