Description

Technical Field

[0001] The utility model relates to the technical field of printing ink supply, in particular to a printing ink supply structure for a printing press. Background Technique

[0002] Generally, there are mainly two types of ink supply structures for inkjet printers, namely ink tank type and ink cartridge type. The advantages and disadvantages of the two complement each other exactly. The ink tank type is suitable for large-volume printing, and the ink cartridge type is suitable for small-volume printing. On the other hand, whether it is the ink tank type or the ink cartridge type, their basic structural components are the same, mainly including: a housing, a stirring structure, a ventilation structure, and an ink outlet structure. In addition, other auxiliary structures such as liquid level monitoring can also be included. Ultimately, it is ensured that even ink containing solid powder pigments can always eject ink evenly, avoiding frequent clogging of the inkjet head of the printer.

[0003] For example, patent number CN202322707979.3 discloses an ink supply structure for an inkjet machine, including a two-time ink path circulation system. The first ink path circulation system includes a main ink tank, an ink tank sealing cover, a DC stirring motor, and a supply ink stirring rod. The ink tank sealing cover is fixedly arranged on the top of the main ink tank, the DC stirring motor is fixedly arranged on the top end of the ink tank sealing cover, the output end of the DC stirring motor penetrates through the ink tank sealing cover and is fixedly provided with a supply ink stirring rod, and the supply ink stirring rod is arranged inside the main ink tank. The second ink path circulation system includes a secondary ink cartridge one and a secondary ink cartridge two. The utility model makes the following through the way of setting a cover plate, a stirring motor, a supply ink pipe, a pneumatic balance pipe, a liquid level sensor, two side baffle units, and an overall stirring blade unit on the barrel body: 1. The overall upper and lower covering type stirring structure, through the reciprocating rotation method, ensures sufficient stirring effect and will not damage the supply ink pipe and the liquid level sensor; 2. The two side baffle units can not only prevent the stirring blade from accidentally knocking against the supply ink pipe and the liquid level sensor, but also ensure that the supply ink pipe and the liquid level sensor are not easily displaced, loosened or damaged by the impact of ink;

[0004] When the ink supply structure in this patent stirs the ink, it is easy to produce uneven stirring phenomenon and thus cause the ink to easily coagulate and precipitate, which affects the ink quality. Moreover, after the ink is stirred, the ink will also remain on the inner wall of the ink supply structure, which is not convenient for cleaning. Content of the Utility Model
