Working Mechanism and Feeding Principle of Leading-edge Feeding Carton Printing Machines

Leading-edge feeding carton printing machines adopt a leading-edge paper feeding structure to complete the separation and conveying of corrugated boards.Different from friction feeding modes,this structure contacts the front edge of paper boards to realize single sheet separation,effectively lowering the probability of double-sheet feeding during operation.The paper feeding part is equipped with adjustable baffle components to adapt to paper boards of different widths.The whole feeding process cooperates with the printing host through synchronous electronic control to ensure stable conveying speed.The feeding system can reduce surface scratch damage on the liner paper of corrugated boards,which is beneficial to protect the integrity of carton raw materials before printing.The equipment sets strict requirements for the stacking state of paper boards.Paper stacks with irregular edges,serious warping or excessive tilting will interfere with the normal separation of the leading-edge feeding mechanism.Operators need to arrange paper boards neatly before feeding to guarantee continuous and stable operation of the feeding system.This feeding structure improves the consistency of paper positioning and creates conditions for accurate overprinting in multi-color printing processes.
