Printer negative pressure adsorption mechanism

Abstract

The invention provides a printer negative pressure steam adsorption mechanism which is installed on a printer and used for adsorbing ink-jet steam. The adsorption mechanism is of a tubular hollow structure and is provided with an adsorption passage and an adsorption portion, one end of the adsorption passage is provided with a connection mouth connected with a negative pressure adsorption device,the adsorption portion is distributed to the lower side surface of the adsorption mechanism and is indented in the middle portion, and a plurality of adsorption holes are distributed in the surface ofthe adsorption portion. According to the printer negative pressure steam adsorption mechanism, by means of the manner that the tubular hollow adsorption mechanism is arranged between spray-head trays, the installation space can be saved to the greatest extent, the overall volume of an inkjet support is reduced, moving of the inkjet support is made to be more convenient, and printing is made to bemore stable; in addition, by means of the arrangement of the indented-type adsorption portion, the adsorption area can be increased, meanwhile, the adsorption space is made to be larger at the same time, and the adsorption efficiency is improved; by means of the manner that the plurality of adsorption holes are arranged in the adsorption portion, full coverage of adsorption can be realized for aplurality of spray heads, and the adsorption effect is made to be better; and by means of the arrangements of the adsorption holes, because the adsorption holes are small, the adsorption holes have better adsorption force.

Description

technical field [0001] The invention belongs to the field of printing equipment, and in particular relates to a negative pressure adsorption mechanism of a printer. Background technique [0002] Inkjet printing technology first appeared in the 1960s. With the gradual maturity of the technology in the mid-1980s, the first commercial inkjet printer was officially born. It sprayed ink onto the surface of various media through the nozzles on the print head to achieve Non-contact, high-speed, low-noise monochrome and color text and image printing. On the basis of inkjet printing technology, the special powder is prepared into ink, controlled by computer, and the configured ink can be directly printed on the surface of ceramics for surface modification or decoration by using a special printer. [0003] At present, the application field is mainly to print on large-sized media such as ceramic tiles, wood boards, glass, corrugated paper, and gussets. By inkjet, various colors of ink...

Problems solved by technology

Therefore, there is usually a high temperature in the printing area, so the inkjet will evaporate to a certain extent. Once the gaseous water molecules with high temperature hit the cold nozzle tray, they will quickly condense into water droplets, and most of these water molecules It is evaporated from the ink, more or less mixed with minerals in the ink, once these water droplets flow into the micropores on the nozzle or mix with the ink ejected from the nozzle, it will pollute the ink and affect the printing effect; in addition, If the steam mixed with minerals spreads further, it will also pollute the surrounding air, and in the long run, it will also have a certain impact on the operator's body
