The adjustment of the height of the folding knife, the main axis of the folding knife is to make planetary motion by the folding roller operating gear, so that the folding knife shaft has autobiography and revolution. The relationship between the sun gear and the number of teeth of the planetary gear is the ratio of the autorotation and the common rotation of the folding knife. To show that because the folding knife autobiography is actually the planetary wheel autobiography, the two-fold knife revolution is the rotation of the folding roller, so that every time the folding roller rotates, the folding knife extends a total of 3 times, the phase difference of 3 times is 120, only Once it is extended downward, it is inserted into the middle of the folding roller to complete the horizontal folding action.
According to the mechanical principle, only when the folding length is equal to half the distance from the center of the folding knife shaft to the center of the folding roller shaft, the movement path of the cutting edge near the folding nip roller is a triangular star curve, and the crease position is accurate. The length of the folding knife is too long, the movement path of the cutting edge at the folding nip roller is a small circle, and the folding knife length is too short, the movement path of the cutting edge at the folding nip roller is a small arc, and the specific adjustment should be folded The height of the knife on the surface of the folding cylinder is 40 cm.
4. Adjust the position of the folding knife and the folding roller, adjust the long hole screw on the folding shaft transmission gear, change the position of the long hole and the screw connection, and change the phase of the folding knife, so as to adjust the folding knife and the folding folder The purpose of the relative relationship.
When adjusting, apply ink to the edge of the folding knife and turn the folding roller to check the coloring of the folding knife and the folding roller. In the condition that the gap between the two folding nip rollers is 0. 02 mm, the folding nip rollers on both sides of the folding knives are not colored. Since a newspaper has been folded into 4 layers here after being folded vertically and horizontally, this precision can meet the requirements for use.
