Description

Ink-jet printing device

Technical Field

The utility model relates to an inkjet printing device especially relates to an inkjet printing device who is used for printing waiting of cylinder cone and prints the object.

Background

The traditional printing mode of the cone (such as a cone-shaped cup) generally adopts a screen printing mode or a trademark pasting mode, the process flow of the screen printing for typesetting, plate making and repeated chromatography is more complicated, the printing cost of small-batch multi-color personalized plate making can be greatly increased, and the personalized printing market is not facilitated. The most important advantage of the ink-jet printing technology is that the printed graphic information can be flexibly changed. The ink-jet printing does not need plate making, has no limit of printing amount, saves all prepress preparation processes of the traditional printing, only needs to input the required image-text information during printing, and can print the required image-text on the object to be printed by using one computer for operation.

Inkjet printing has become increasingly popular in recent years due to its higher printing speed and superior image resolution, and the greater flexibility in the design and layout of the final image that is achieved by the use of inkjet printing devices in conjunction with computers.

Inks used in prior art inkjet printers include water-based inks, solvent-based inks, and UV inks. Aqueous inks are used with porous substrates or substrates having a coating of a specific receptor that absorbs water. When used for printing water-based ink on a coated and non-porous film, the effect is not ideal. Solvent-based inks are suitable for printing on non-porous films, but most solvent-based inks contain about ninety percent by weight of organic solvent. When solvent-based inks dry, the solvent evaporates and creates a pollution hazard to the environment. Although there are some environmental systems available in the prior art that can be used to reduce the emission of solvent to the atmosphere, these environmental systems are expensive. And the inkjet printing apparatus using the water-based ink and the solvent-based ink requires a relatively large amount of solvent and water to be dried during the printing process, which limits the speed of the entire printing process. And the UV printing ink can be cured immediately, so that the printing speed is high, and the printing ink can be widely applied to media. Adopting UV printing ink to carry out inkjet printing work needs a solidification equipment to work with it, and solidification equipment's effect has two points: spreading is controlled, the ink flows and infiltrates on a medium to be printed, and the position and the shape of the ink can be shaped by proper curing, so that the ink is necessary in occasions with high requirements on jet printing precision; curing to dry the ink, crosslinking the internal molecules, and fully curing to affect the performances of the ink such as adhesive force, hardness and the like.

The curing device in the inkjet printing apparatus is generally disposed on both the left and right sides of the printing carriage or on one side of the printing carriage. The printing carriage carries a curing device which ejects ink droplets onto the printing medium during the reciprocating movement, and the curing device cures the ink droplets ejected onto the printing medium while the printing medium is stationary during the printing. Because the curing device of the ink-jet printing device is close to the printing head, ultraviolet light emitted by the curing device during operation is easily directly radiated to the plane of the printing head nozzle or reflected to the plane of the printing head nozzle after being refracted by a printing medium to cure and dry ink on the surface of the nozzle, so that the printing head nozzle is blocked.
