Adjustment of the paper receiving part of the offset press during printing

1 Time and displacement

during printing, the paper receiving cylinder takes paper from the imprinting cylinder. The time and displacement must be matched accurately to ensure stable paper taking. When the position of the imprint cylinder is determined, the position of the paper receiving cylinder is also determined and cannot be adjusted. When the position of the chain row is found to be inappropriate, you can only adjust the chain row, not the paper receiving roller. When the position of the jaw at the receiving stack is not appropriate, only the jaw can be adjusted, not the receiving chain row. Therefore, the paper receiving drum is the absolute benchmark for the adjustment of the paper receiving part, and the paper receiving chain is the relative benchmark for the adjustment of the paper receiving part

the adjustment of the tooth pad of the paper receiving chain row should be based on the tooth pad of the embossing cylinder, and the adjustment of the tooth pad of the chain row should be based on its own tooth pad. Therefore, the tooth pad of the embossing cylinder is the absolute benchmark for the adjustment of the tooth pad of the paper receiving chain, and the international influence of the plastic extruder industry of the tooth pad of the paper receiving chain continues to rise as the relative benchmark for the adjustment

generally, the user can adjust the paper receiving chain row as follows when using it: the position of the tooth pads at both ends of the chain row usually does not change, that is, it can ensure the function of relative benchmark. At this time, the position of the middle tooth pad can be calibrated with the tooth pads at both ends, and then the position of the dental slice can be calibrated

2. Paper size

the size of paper size directly affects the amount of powder spraying, and the area of powder spraying must be adjusted according to the size of the paper. The position of the brake roller and the position of the side paper aligning mechanism should also be adjusted with the change of the paper size. The adjustment benchmark of these components is the front Qi cardboard, because the position of the front Qi cardboard set by former Cui Lixin is not adjustable for many years
