Ink storage device for ink-jet printer

Abstract

The invention discloses an ink storage device for an ink-jet printer. The ink storage device comprises an ink box and an ink barrel used for feeding ink into the ink box. The ink box comprises a shell, a flow guide plate and an ink baffle, the flow guide plate is mounted in the shell and comprises an ink guide plate and an upper ejector plate, the ink guide plates are obliquely arranged at outlets of an ink inlet tube and an ink return tube, the upper ejector plate is connected with the upper ends of the ink guide plates, and a bubble passage is formed between the upper ejector plate and the upper top face of the shell. The ink baffle is arranged on the lower portion of the flow guide plate, a gap for ink feeding is reserved between the ink baffle and the side wall of the shell, an ink containing gap is reserved between the ink baffle and the inner bottom face of the shell, the lower end of an ink outlet tube penetrates through the ink baffle to extend into the ink containing gap, and a bubble guide device is arranged in the bubble passage and used for guiding bubbles away and eliminating the bubbles. Replacement of the ink box is not needed, so that printing cost is saved. In addition, bubbles in the ink box are effectively eliminated, and accordingly printing quality is improved.

Description

technical field [0001] The invention relates to the technical field of inkjet printing machines, in particular to an ink storage device for inkjet printing machines. Background technique [0002] With the development of inkjet printing technology, currently commercially available inkjet printers provide ink sources from ink cartridges, and transport ink to nozzles through ink delivery tubes. The nozzles eject ink onto printing media such as paper under the drive of printing signals. To complete the printing of characters or graphics. [0003] However, in the existing inkjet printing machine, its ink cartridge must be replaced after being used for a period of time because of its ink depletion. The common replacement method is to discard the depleted ink cartridge of its ink and replace it with a new ink cartridge. In order to provide the ink source, this method inevitably causes waste of the ink body of the ink cartridge. [0004] In addition, for inkjet printers using the ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide an ink storage device for an inkjet printing machine, which firstly solves the problem of waste caused by replacing ink cartridges and saves printing costs. Air bubbles cause the pressure instability of the ink supply system, which improves the printing quality
