Automatic ink color blending apparatus

An automatic ink color blending apparatus, characterized in that the automatic ink color blending apparatus comprises:

• an apparatus cabinet (1) having a carrying platform (11),
• an ink bucket moving platform (2) provided on the carrying platform (11) wherein the ink bucket moving platform (2) includes a moving guide rail (21), a weighing device (22) and an ink bucket (23)with the ink bucket (23) being disposed on the weighing device (22),and the weighing device (22) being disposed on the moving guide rail (21) and moving along the moving guide rail (21),
• an ink supply tank (3) arranged above the ink bucket movement platform (2), wherein the ink supply tank (3) includes a plurality of ink supply devices (31), each one of which provides inks of different chromaticity,
• a control terminal (4), provided on the carrying platform (11), electrically connected with the ink supply tank (3), the moving guide rail (21) and the weighing device (22) respectively wherein, the control terminal (4) obtains target chromaticity information, generates control information of ink selection according to the target chromaticity information, selects one or more ink supply devices (31) to inject the ink with corresponding chromaticity into the ink bucket (23) successively, and the weighing device (22) performs on-line weighing of the amount of the injected ink for each type of chromaticity so that the actual injection amount of the ink for each type of chromaticity is same as the amount desired to be injected, further the control information of ink selection includes selection information of an ink device and information of the amount of ink desired to be injected.
