The invention relates to a ceramic large plate inkjet machine, which includes a main machine, one or more slave machines and a tail machine. The main machine, the slave machines and the tail machine are connected and spliced successively, the main machine, the slave machines and the tail machine are provided with independent suspension cages correspondingly, and printing spraying heads are installed in the suspension cages; the main machine, the slave machines and the tail machine are provided with independent ink supply systems correspondingly, and the ink supply systems circularly transportink to the printing spraying heads in the suspension cages; corresponding inkjet systems of the main machine, the slave machines and the tail machine are provided with one or more color channels; theceramic large plate inkjet machine further includes a bottom belt transmission mechanism, the bottom belt transmission mechanism passes through the main machine, the slave machines and the tail machine, and is used for transporting print substrate materials; the corresponding suspension cages of the main machine, the slave machines and the tail machine are arranged at equal interval on the upper part of the bottom belt driving mechanism; and the main machine, the slave machines and the tail machine are provided with the independent suspension cages capable of ascending and descending synchronously. According to the ceramic large plate inkjet machine, the printing width of the ceramic large plate inkjet machine is large, and the number of the color channels can be freely quantified; and theceramic large plate inkjet machine is of a separated structure, free disassembly and assembly can be achieved, and synchronous ascending and descending of each suspension cage can be achieved.
