Abstract

The invention provides an ink supply control system, a printing machine and an ink supply control method; wherein the ink supply control system comprises at least one ink inlet electromagnetic valve which is arranged between an ink inlet cavity and a spray nozzel; at least one ink return electromagnetic valve which is arranged between an ink return cavity and the spray nozzle; a control device, which is electrically connected with the at least one ink inlet electromagnetic valve and the at least one ink return electromagnetic valve and is used for controlling the working states of the at leastone ink inlet electromagnetic valve and the at least one ink return electromagnetic valve according to different working instructions; the ink supply control system provided by the invention has a simple structure, saves the consumption of ink during ink drop maintenance of the printing machine of a spliced module sub-nozzle, increases the service life of the nozzle, accurately controls the actual ink drop time, and avoids the difficulty of frequently replacing the spliced module nozzle.

Description

technical field [0001] The invention relates to the technical field of ink supply in inkjet printing, in particular to an ink supply control system, a printing machine, and an ink supply control method. Background technique [0002] In the field of inkjet printing technology, nozzle splicing modules are usually used in inkjet printers to print wide-format printing jobs. Such as figure 1 The shown splicing sub-spray head module equipment has three print heads (the first print head 102, the second print head 104, the third print head 106), from figure 2 From the top view shown, it can be seen that the first nozzle 102, the second nozzle 104, and the third nozzle 106 effectively expand the printing width and integrate the functions of installing two or more nozzles in a single module. In the current technical scheme, only one secondary ink cartridge is installed in a splicing module, and ink will be delivered from the ink inlet cavity in the secondary ink cartridge to all no...
