Anti-backflow section-by-section ink supply type continuous supplying ink box integrated with front cover

Abstract

The invention relates to an anti-backflow section-by-section ink supply type continuous supplying ink box integrated with a front cover. The anti-backflow section-by-section ink supply type continuoussupplying ink box comprises the front cover used for being hinged to the front end of a printing machine, an ink storage bin used for storing ink, air pressure bins used for balancing the air pressure of the ink storage bin, ink suction pipes used for sucking the ink in the ink storage bin, air pressure buffering pipes used for buffering the air pressure, an integrated pipeline and ink conveyingpipelines. The anti-backflow section-by-section ink supply type continuous supplying ink box is hinged to the front end of the printing machine through hinged inserting heads, compared with an external continuous supplying ink box in the prior art, the overall consistency is greatly improved, external ink box damage is avoided, and transport is convenient; the ink is supplied more stably in the section-by-section mode, and the anti-backflow function is achieved; and the air pressure buffering pipes have the ink leakage preventing function.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to an anti-backflow segmented ink supply continuous ink cartridge integrated in a front cover. Background technique [0002] Printers are commonly used office supplies, and ink and paper are necessary consumables. In order to continue to earn ink profits after the printers are sold, the printer manufacturers in the prior art design the ink cartridges of the printers as a style that needs to be replaced, and they need to be purchased separately every time they are used up. The condition of the ink. [0003] Some simple continuous supply ink cartridges have appeared in the prior art, and the ink cartridges are directly connected to the printer through pipelines, but they are prone to backflow problems and ink leakage problems, and the continuous supply ink cartridges do not match the structure of existing printers. It can only be placed outside the printer, and it is easy to break....
