For the adjustment of the height of the folding knife, the main shaft of the folding knife relies on the operating gear of the folding cylinder for planetary movement, so that the folding knife shaft has both autobiography and revolution. The transmission ratio of the autobiographical and co-rotation of the folding knife is expressed by the relationship between the number of teeth of the sun gear and the planet gears. Since the autobiography of the folding knife is actually the autobiography of the planetary gear, the revolution of the two folding knife is the rotation of the folding cylinder. In this way, the folding knife protrudes a total of 3 times per revolution of the folding cylinder, and the phase difference between the three times is 120, only the downward extension Only once, the report is inserted into the middle of the folding pinch roller to complete the horizontal folding action.
According to the mechanical principle, only when the folding length is equal to half of the distance from the center of the folding knife shaft to the center of the folding drum shaft, the movement path of the blade near the folding nip roller is a triangular star curve, and the folding position is accurate. If the folding knife length is too long, the movement path of the blade at the folding pinch roller is a small circle, while the folding knife length is too short, the moving track of the blade at the folding pinch roller is a small circular arc. The protruding height of the folding knife on the surface of the folding cylinder is 40cm.
Adjust the position of the folding knife and folding roller, adjust the long hole screw on the transmission gear of the folding knife shaft, and change the position of the long hole and the screw to change the phase of the folding knife, so that the relative position of the folding knife and the folding folder The purpose of the relationship.
When adjusting, apply ink to the blade of the folding knife, rotate the folding cylinder, and check the coloring of the folding knife and folding roller. Under the condition that the gap between the two folding nip rollers is 0.02 mm, it is appropriate that the folding nip rollers on both sides of the folding knife are not colored. Since a newspaper has been folded into four layers here after being folded vertically and horizontally, the accuracy can meet the requirements of use.
