Abstract

The invention belongs to the technical field of printing, and discloses a constant-liquid-level hydraulic ink supply system. The system is used for solving the problems that an existing ink supply device is complex in structure and unstable in liquid level hydraulic pressure. The system comprises a mounting base, a printing spraying head is arranged on the mounting base, and is provided with an ink bag device, and the system is characterized in that the ink bag device comprises a plurality of ink bag cavities, an ink bag cavity gland is arranged at the upper end of each ink bag cavity, each ink bag cavity is provided with an ink bag ink inlet, an ink bag ink outlet and an ink bag heating pipe used for heating ink in the ink bag cavity, and an ink bag soft film is arranged between each ink bag cavity and the corresponding ink bag cavity gland.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to a constant liquid level hydraulic ink supply system. Background technique [0002] Inkjet printers are equipped with an ink supply device that continuously supplies ink to the nozzle. The ink supply device is divided into negative pressure ink supply and constant pressure ink supply. The constant pressure ink supply is realized according to the principle of siphon, so that the ink liquid level in the ink cartridge The height difference of the nozzle of the printer maintains a relatively stable value to realize the control of the ink supply point of the nozzle of the printer. [0003] For example, the utility model patent with application number 201120041330.7 discloses a constant-pressure ink supply device for inkjet printers, which includes several sub-ink boxes that can be connected to the nozzles of the printer through ink delivery tubes. The sub-ink boxes are sup...
