Viscometer and ink supply system

Abstract

The invention discloses a viscometer and an ink supply system, and relates to the field of printers. The viscometer comprises a containing part; a base formed by extending outwards along one end of the containing part, wherein the base is conical, an ink injection port is formed in the side wall of the base, and an ink discharging pipe is further arranged at the bottom of the base; a top cover arranged opposite to the base and fixed to the other end of the containing part; and an electrode assembly fixed to the top cover and located in the containing part, and wherein the electrode assembly is used for determining the time required for emptying the ink with the preset capacity in the containing part. According to the viscometer and the ink supply system, the viscosity of the ink can be detected, and meanwhile the ink can be fully mixed and stirred.

Description

technical field [0001] The invention relates to the field of printers, in particular to a viscometer and an ink supply system. Background technique [0002] Continuous inkjet printers typically consist of a main structure that includes two compartments, one housing the ink supply and the other housing the electronics, and is connected to the main structure by conduits containing a number of pipes and wires of the print head. [0003] The ink supply system pumps the ink under pressure to the print head, and then into the spray chamber containing the nozzles, through which the ink is formed into continuous jets. Generally, during the printing process, a large amount of inkjet will be collected by the recovery tube, and then it will be recovered to the ink supply system by a suction pump, so that the ink can be reused. [0004] However, since the recovery tube is open and the ink and air mixture is introduced into the recovery tube using pumping techniques, air is inevitably ...

AI Technical Summary

Problems solved by technology

Although pigmented inks have good opacity and are the only practical way to convey white codes, they have some notable drawbacks: The inks are made from suspensions of submicron particles that have a tendency to agglomerate and can Causes clogging of filters or jetting nozzles; pigmented inks are composed of dense particles that have a tendency to settle at rest, causing loss of opacity

However, agitating the ink in the mixing tank exacerbates another known problem: the tendency of the ink to foam as it returns from the printhead to the ink-air mixture

However, such systems are expensive, complex, contain mechanical components subject to wear, and, for best results, must be active even when the printer's fluid system is shut off
