How to adjust the receiving part of sheet-fed offset printing machine
1. Time and displacement The take-up roller takes the paper from the impression cylinder, the time and displacement must be matched accurately to ensure the smooth take-out. After the position of the impression cylinder is determined, the position of the take-up cylinder is also determined and cannot be adjusted. When it is found that the position of the chain row is not suitable, the chain row can only be adjusted, but not the receiving roller. When the position of the splint at the stack of paper is not suitable, you can only open the splint, not the chain of the sprocket. Therefore, the delivery roller is the absolute reference for the adjustment of the delivery section, and the delivery chain is the relative reference for the adjustment of the delivery section. The adjustment of the dental pads of the delivery chain should be based on the dental pads of the impression cylinder, and the adjustment of the dental pads of the chain row should be based on its own dental pads. Therefore, the tooth pad of the impression cylinder is the absolute reference for the adjustment of the pads of the delivery chain, and the tooth pad of the delivery chain is the relative reference for adjustment. Under normal circumstances, users can adjust the delivery chain row as follows: the position of the dental pads at both ends of the chain row usually does not change, that is, it can ensure the role of the relative reference, then the dental pads at both ends can be used to correct the position of the intermediate dental pads. Then come to calibrate the position of the dental disc. 2. Paper format The size of the paper format directly affects the amount of powder sprayed, and the area of ​​powder sprayed 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 as the paper width changes. The adjustment basis of these components is the front paper board, because the position of the front paper board cannot be adjusted.
