Abstract

The present invention relates to the technical field of carton printing machinery, and more specifically, to a paper feeding method that simultaneously descends and time-shares to raise and lift boards. The invention does not damage the strength of the cardboard under the premise of ensuring that the paper feeding accuracy is not affected, improves the competitiveness of the printing machine, simplifies the mechanical structure of the printing machine, and improves the paper feeding quality.

Description

Technical field [0001] The present invention relates to the technical field of carton printing machinery, and more specifically, to a paper feeding method that simultaneously descends and raises a lifting plate in a time-sharing manner. Background technique [0002] The servo leading edge paper feeding of the carton printing machine is coordinated with the precise movement of the paper feed wheel and the grid plate controlled by the servo drive and the vacuum suction cardboard fixing system of the appropriate size to ensure that the cardboard is fed into the machine. A carton printing machine generally only has one paper feeding unit. Once the paper feeding function is activated, the function of the grille is to ensure that the cardboard is positioned around the feeding roller and lowered so that the cardboard is in contact with the feeding roller. When the paper feed mode is activated, the wheel speed is almost zero, but it can be quickly accelerated by the servo drive to reach...
