The adjustment of the height of the folding knife, the main axis of the folding knife is to make the planetary movement by the operation gear of the folding cylinder, so that the folding knife shaft has the autobiography and the revolution. The transmission ratio of autobiography and co-rotation of knives is expressed by the relationship between the number of teeth of the sun gear and the number of teeth of the planetary gear. Since the autobiography of the knives is actually the planetary wheel autotransport, the revolution of the two-fold knives is the rotation of the folding cylinder. In this way, the folding knives are extended three times for each revolution of the folding cylinder. The phase difference is three times and it is only 120 degrees downwards. Once out, it only interleaves between the folding rollers to complete the transverse folding action.
According to the mechanical principle, only when the folding length is equal to half of the center of the folding knife shaft to the center of the folding roller shaft, the trajectory of the cutting edge near the folding pinch roller is a triangular star curve, and the folding seam position is accurate. If the length of the knife is too long, the trajectory of the knife edge at the folder nip roller is a small circle. When the length of the knife is too short, the trajectory of the knife edge at the folder nip roller is a small arc, and the specific adjustment should be made The protruding height of the folding knife on the surface of the folding roller is 40cm.
Adjust the position of the folding knife and folding roller, adjust the long hole screw on the gear shaft 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 folding clamp can be adjusted. The purpose of the relationship.
When adjusting, apply ink to the knife edge of the knife, rotate the folding roller, and check the coloring of the folding knife and the folding pinch roller. In the case where the gap between two folding nip rollers is 0.02 mm, it is not preferable that the folding nip rollers on both sides of the folding blade are colored. Since a newspaper has undergone vertical and horizontal folding, it has been folded into four layers here, so this accuracy can meet the requirements for use.
