Transfer ink bin of printing machine

Abstract

The invention provides a transfer ink bin of a printing machine. The transfer ink bin comprises a bin body. An overflow cavity is defined in the bin body by a transverse partition plate, a bin body inner wall and a first vertical partition plate which are arranged in the bin body. A flow return cavity is defined in the bin body by the transverse partition plate, the bin body inner wall and a second vertical partition plate arranged in the bin body. An ink supply cavity is defined in the bin body by the first vertical partition plate, the second vertical partition plate and the bin body inner wall arranged in the bin body. The ink supply cavity communicates with the flow return cavity. An ink supply pipe communicating with the bin body is arranged at the top end of the bin body. The ink supply pipe is used for supplying ink to the flow return cavity. An ink outlet pipe and an overflow flow return pipe which communicate with the bin body are arranged at the bottom end of the bin body. The ink outlet pipe communicates with the ink supply cavity, and the overflow flow return pipe communicates with the overflow cavity. When the ink exceeds the height of the transverse partition plate and the first vertical partition plate, excess ink can overflows into the overflow cavity from the ink supply cavity and the flow return cavity, the phenomenon that the ink is too full to overflow out of the bin body is avoided, and the ink in the overflow cavity can automatically flow back into an ink barrel through a soft pipe communicating with the overflow flow return pipe.

Description

Technical field [0001] The invention relates to the technical field of printers, in particular to a transfer ink warehouse of a printer. Background technique [0002] Inkjet printers can be divided into solid inkjet and liquid inkjet according to their working principles, and liquid inkjet printers can be divided into bubble type and liquid piezoelectric type. Among them, the bubble type is to heat the nozzle to make the ink generate bubbles, which are ejected onto the printing medium to complete printing. When the ink of the ink cartridge in the printer is used up, you can continue printing by directly replacing the ink cartridge. However, because the internal space of the printer is relatively small, the built-in ink cartridge can hold the volume of ink is relatively small. When a large number of reports are to be printed, such as printing patient test reports in a hospital, the ink cartridges need to be replaced frequently, which is inconvenient to complete a large amount of ...

AI Technical Summary

Problems solved by technology

However, although the printer is equipped with such an automatic ink supply system, the external ink barrels in this system are directly connected to the built-in ink cartridges, and there is still a risk of ink overflow during ink supply, and this ink supply system is not easy to maintain
