Description

Gravure proofing machine Technical Field The utility model relates to the technical field of intaglio printing, in particular to an intaglio proofing machine. Background In the field of printing, a gravure proofing machine is a key device for verifying the quality and printing effect of a printing plate, and generally comprises a plate roller coated with ink, a printing roller wound with a printing piece and other basic components, wherein the ink on the plate roller is transferred onto the printing piece of the printing roller during proofing so as to realize sample output. A conventional intaglio proofing machine in the prior art is shown in a patent with the application number of CN200510033541.5, a rubber drum is arranged on a frame through an upper sliding seat and a lower sliding seat, the upper sliding seat and the lower sliding seat are guided by guide rails, a tailstock part comprises a left tailstock and a right tailstock, the left tailstock and the right tailstock are matched with a transverse screw rod arranged on the frame, and the left tailstock and the right tailstock are driven by the screw rod driven by a motor to clamp a plate roller. After the technical scheme is adopted, firstly, the rubber drum is driven to advance through the sliding of the upper sliding seat and the lower sliding seat and the twice feeding, so that the upper sliding seat and the lower sliding seat can cooperatively work for the movement with larger displacement, and the rubber drum is driven to move only through the upper sliding seat for the movement with smaller displacement.
