Abstract

The invention discloses a three-roller printing and driving device of a gravure printing machine, comprising an embossing roller, a rubber roller and an edition roller, wherein the embossing roller, the rubber roller and the edition roller are fixed on both side wallboards, and a large embossing cylinder and a small embossing cylinder are provided at the same time. The large embossing cylinder ensures the pressure between the rubber roller and the edition roller, and the small embossing cylinder ensures the pressure between the embossing roller and the rubber roller. The embossing roller and the edition roller are respectively provided with an edition roller driver and an embossing roller driver, and double drivers respectively comprise a PCC (Programmable Computer Controller) servo control system, a servo driver and a servo motor. By utilizing a double-drivers control manner, power is applied on a press roller, and the synchronization of each color of embossing roller and the linear velocity of the edition roller during active control can be ensured.

Description

technical field [0001] The invention relates to a gravure printing mechanical device, in particular to a three-roller printing and driving device of a gravure printing machine. Background technique [0002] The embossing unit is the core component of the gravure printing machine. The current embossing unit of the gravure printing machine all adopts the method of transferring patterns directly to the printing substrate, that is, the material film, by the plate roller for printing. This method meets the needs of most printed products, but at the same time, for some users with special needs, it is not necessary to use this method of directly transferring patterns from the plate roller to the material film for printing. Not enough. Some printing companies transfer the pattern to the rubber roller through the plate roller for the printing of some substrates due to the factors of technological secrecy and the requirements for special printed products, and then print the pattern ...
