Description

Ink refilling machine

The present invention relates to a printing press, and more particularly, to an ink refilling apparatus of a printing press having an improved structure so that ink can be quickly supplied to an ink cartridge embedded in a printer main body.

In general, a printing machine applied to a computer laser printer or a copier includes a dry developing method using powdery toner, and a wet developing method using a developer in which toner is mixed with a liquid carrier. Both of these methods transfer electrostatic toner or developer to a photosensitive medium on which an electrostatic latent image is formed, and then pass a sheet of paper between the rotating transfer medium in contact with the photosensitive medium to print a desired image on the recording paper. Use

In the conventional electrophotographic printing machine, the method of supplying ink to the developing unit is made through an ink cartridge installed close to the lower side of the developing unit, which involves difficulty in allocating space inside the printing machine. That is, the position of the developing unit is limited to the position close to the lower surface of the photosensitive belt, so the installation position of the ink cartridge has to be limited in consideration of problems such as the volume of the ink cartridge installed in the printing press, replacement of ink, replenishment, cleaning and repair. .

In consideration of this point, a method of fixing the ink cartridge at a location not limited by the installation space and supplying ink to the fixed ink cartridge using a separate refill cartridge may be employed. This method is inexpensive because only refill cartridges, which are consumables, can be replaced without replacing functional parts such as agitators, dripless valves, air holes, and a detachment device in a general ink cartridge.

However, when the refill cartridge is adopted, when the ink in the refill cartridge is injected into the ink cartridge, the time required for the injection becomes long, which is inconvenient as the waiting time of the user is extended.

The present invention was conceived in view of the above problems, and an object thereof is to provide an ink refilling apparatus for a printer which can supply a concentrated ink to an ink cartridge by employing an ink refill cartridge.
