Description
Technical Field
The utility model relates to the technical field of ink-jet printing equipment, in particular to a secondary ink box for an ink-jet printer.
Background
The automobile glass is visible everywhere in life, and can be generally divided into front windshield glass, rear windshield glass, door glass, triangular window glass and skylight glass, and from the aspect of manufacturing technology, the automobile glass processing is mainly divided into three steps of cutting large sheets, cutting, grinding, washing, baking and printing, wherein in the printing step, the printed objects mainly comprise three steps: black border, heater wire and trademark. Traditional automobile glass printing adopts a screen printing mode, namely, glass screen printing is performed on glass products by using a screen printing plate and glass glaze. The glass glaze is also called glass ink, and is a pasty printing material formed by mixing coloring materials and binder, wherein the coloring materials comprise inorganic pigment and low-melting-point fluxing agent (lead glass powder), and the binder is commonly called as plate benefiting oil in the glass screen printing industry. The printed glass product is fired in a furnace at 520-600 ℃ to form patterns by consolidating the glaze printed on the surface of the glass.
However, the glass screen printing process is easy to have quality problems such as plate pasting, pinhole phenomenon, bubble in ink, outward expansion of printing size, spot shape in image-text part and dark tone part, and the like. The reasons for these problems are mostly due to the influence of the printing environment, the specificity of the glass ink and the defects of some uses of the screen printing plate itself, for example, the glass surface is not treated cleanly, dirt such as watermarks, fingerprints, mimeographies, dust particles and the like can cause the paste plate, the volatilization solvent in the glass ink is volatilized quickly due to the excessively high temperature and the relatively low humidity of a workshop, or the fluidity of the glass ink is deteriorated due to the excessively low temperature of the workshop, the viscosity of the ink is increased, the meshes of the screen printing plate are blocked, or the coloring material in the glass ink is separated from the solvent, precipitation is generated, and the meshes of the screen printing plate are blocked, so that the printing quality is affected. In addition, with the advent of the information age, the production of automobile glass is also continuously adapted to the needs of the age, for example, the corner mark of the front windshield will gradually evolve into two-dimension codes representing the identity of each automobile, the two-dimension codes can trace back the country of production, manufacturing company or manufacturer (looking up price, reference, preferential policy), automobile model, brand name, automobile series, automobile body form, engine model, automobile model, safety protection device model, inspection number, assembly factory name, factory number and the like of the automobile, and the information including the engine, transmission, braking system and the like configured by the automobile manufacturer can be scanned and read, so the printing of the automobile corner mark is approaching to personalized customization, and the traditional screen printing cannot be adapted to the customization needs due to the limitation of plate making.
Therefore, the mode of printing marks, black edges, heating wires and the like on the automobile glass by adopting a variable data ink-jet printing technology through an ink-jet printer is generated, so that the personalized customization requirement of the automobile glass is met. In the ink supply system of the ink-jet printer, the glass ink has low fluidity, which is easy to cause ink path blockage, and the glass ink has high fluidity, which is easy to cause ink drop diffusion after printing, so that printed patterns are fuzzy and the boundaries are unclear, and particularly, the subsequent reading and identification of the patterns of the type of two-dimensional codes can be influenced; in addition, the content of the lead glass powder in the glass ink entering the printing nozzle is also required to be in a proper proportion, if the proportion of the lead glass powder is too large, the nozzle of the printing nozzle is extremely easy to be blocked, and the insufficient content of the lead glass powder can cause insufficient adhesive force of a pattern on glass after subsequent firing, so that the quality requirement cannot be met.
In the ink supply system of the ink jet printer in the prior art, a secondary ink box is usually arranged in an ink path which is close to a printing nozzle, ink flows into the secondary ink box from a main ink tank, and then the secondary ink box supplies ink to each printing nozzle. The liquid level sensor in the prior art is mostly a contact type liquid level sensor and needs to be arranged in a secondary ink box, such as a secondary ink box disclosed in Chinese patent CN103832080B, and comprises an ink box body and an ink box cover, wherein a sensor mounting hole is formed in the horizontal part of the ink box cover and is used for mounting the liquid level sensor, and the liquid level sensor is a secondary liquid level float sensor. The secondary liquid level float sensor is a contact type liquid level sensor, the contact type liquid level sensor needs to be in direct contact with liquid, the liquid level height is measured by measuring the conductivity or the capacitance of the liquid, but for special ink such as glass ink, the consistency and the viscosity are higher, when the liquid level rises and falls, more ink still adheres to the liquid level sensor, and the liquid level sensor can be caused to erroneously measure to be a high liquid level, so that the secondary ink box lacks ink.
Therefore, how to avoid ink precipitation in the secondary ink cartridge and how to accurately measure the liquid level in the secondary ink cartridge becomes a key technical problem to be solved when the ink jet printer prints glass.
