Therefore, at present, there is an urgent need for a print machine which can synchronously lift the two ends of the press roller, so as to ensure the quality of prints, and meanwhile, the press machine needs to forcibly press the electric print machine and other related products with the same function on the use cost of the function, so that the print machine with the practicability can be popularized and applied in large scale in colleges and universities and other artistic institutions.

The existing engraving machine has the defects in the aspect of realizing pressure balance. Because the required impression power of upper roll is leaned on both sides spiral closing device control at the printing in-process of traditional commercial engraving coining mill, before printing, drives the slider through rotatory handle and reciprocates on the guide rail of portal frame to adjust the impression power of upper roll to the drawing board, but only rely on experience and feel when adjusting pressure, there is left and right pressure imbalance.
