Automatic pressure regulation system of multi-color flexographic roller printing machine based on fpga

Abstract

The invention provides an FPGA-based automatic pressure regulating system of a multi-color flexo roller printing press. The automatic pressure regulating system is used for solving the technical problem that in an existing multi-color flexo roller printing press, the pressure regulating efficiency is low. The automatic pressure regulating system comprises a human-machine interface, controllers and a plurality of multi-color pressure regulating mechanisms. The controllers comprise the master controller and a plurality of slave controllers. Each multi-color pressure regulating mechanism comprises a plurality of single-color pressure regulating mechanisms. Each single-color pressure regulating mechanism comprises four servo motor drivers, four servo motors, flexo rollers, ink rollers and impression rollers. The master controller is directly connected with the slave controllers and controls the slave controllers in parallel according to an instruction of the human-machine interface, the slave controllers control different servo motor drivers of the corresponding multi-color pressure regulating mechanisms, the servo motor drivers control the servo motors to drive the flexo rollers and the ink rollers to move, and thus the inking pressure and the printing pressure are regulated. The automatic pressure regulating system can be applied to the field of multi-color flexo roller printing presses.

Description

technical field [0001] The invention belongs to the technical field of printing machinery control, and relates to an automatic pressure regulating system of a multi-color flexographic roller printing machine, and specifically designs an automatic pressure regulating system of a multi-color flexographic roller printing machine based on FPGA, which can be used for multi-color flexographic roller printing machines. The field of printing presses. Background technique [0002] Flexographic printing plate is a letterpress made of rubber plate, photosensitive resin plate and other materials, so flexographic printing belongs to the category of letterpress printing. Flexographic printing has the characteristics of letterpress printing, offset printing and gravure printing. From the structure of the printing plate, its graphic part is raised, higher than the blank, and has the characteristics of embossing; from its printing suitability, it is the flexible offset printing surface that...
