Abstract

The invention relates to the technical field of carton printing machines, in particular to a paper feeding method lowering lifting plates at the same time and elevating the lifting plates at different time. According to the paper feeding method, the strength of a paper board is not damaged on the premise that the paper feeding precision is not affected, the competitive power of a printer is improved, meanwhile, the mechanical structure of the printer is simplified, and the paper feeding quality is improved.

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 time-shares to raise and lift boards. Background technique [0002] The servo leading edge feeding of the carton printing machine is through the precise movement of the feeding wheel and grid plate controlled by the servo drive and the appropriate size of the vacuum suction cardboard fixing system to ensure that the cardboard is fed into the machine. A carton printing machine is generally equipped with only one paper feeding unit. Once the paper feed function is activated, the function of the grid is to ensure that the cardboard is lowered around the feed roller so that the cardboard is in contact with the feed roller. When the paper feed mode is activated, the wheel speed is almost zero, but can be quickly accelerated by the servo drive, reaching 100% of the machine's tangential speed and...
