Description

Adjustment structure of head's positon in Digital Printing Machine

The present invention relates to a head position adjusting structure of a digital printing machine, and more particularly, to a device capable of adjusting the position of the head for ejecting ink in the horizontal direction and the rotation direction.

In general, a digital printing machine uses a subtractive blending technique that creates various colors by using three primary colors such as magenta, yellow, and cyan, and creates various colors. I used black temple color for.

In order to use the subtractive mixing technique, ink having each color is individually received and supplied to the head for scanning each color, so that ink of the color scanned from each head is overlaid so that a new color is exhibited.

A digital printing machine having the above principle will be briefly described with reference to FIG.

A rail-shaped transfer table 5 is installed on the upper base 3 supported by both legs 1, and a cartridge 9 having the head portion 7 fixed to one side is transferred to the transfer table 5. Possibly combined.

And, the media (media) is supplied from the paper feed roller 11 installed on the back of the digital printing machine to the upper surface of the base 3, when the cartridge (9) is reciprocated left and right on the upper surface of the media, In cooperation with the ink of the predetermined color is scanned from the head portion 7 is performed a printing operation.

The media is a term known in the art, and refers to an object for outputting ink ejected by the head portion 7 such as paper or cloth.

As shown in FIG. 2, the structure of the head part 7 is formed by a lower case 22 and an upper case (not shown), and a portion of the lower case 22 is cut off to allow passage of a wiring. Wiring holes 25 are formed.

In the lower case 22, a head 26 for injecting ink of different colors forms a predetermined angle with the head portion 7 in the moving direction, and an injection hole of the head in the insertion hole 30 formed in the lower case 22. 27 is inserted and mounted.

Screw holes 32 are provided at both sides of the insertion hole 30, and a fixing bracket 40 having a through hole 42 corresponding to the screw hole 32 is mounted on the top of the head 26.

In addition, separate fastening holes 44 for fixing the top of the head 26 and the fixing bracket 40 to each other are formed, respectively, and the fixing bracket 40 is attached to the head 26 and the screw hole 32, respectively. Fixing screw 46 is used to fasten.

On the other hand, the ink supply line 48 is connected to the head 26 through the fixing bracket 40 to supply the ink stored in the outer tank to the head 26, the injection hole 27 below the head 26 Ink is injected into the media through the media.

Then, the head portion 7 is moved left and right along the conveyer 5, the ink ejected through each head 26 is injected into the media to obtain a desired output.

The reason why the head 26 is mounted on the lower case 22 in an inclined manner is to increase the resolution by spraying more ink into the unit space.

The head 26 of the conventional digital printing machine as described above is fixed to the lower case 22 by a fixing screw 46 and a fixing bracket 40.

For this reason, the head 26 may be caused by a manufacturing failure such that the insertion hole 30 or the screw hole 32 is manufactured at a position different from the set position, or the fixing bracket 40 is manufactured at a different size from the design dimension. ), The desired output is not obtained because the ink is not ejected to a predetermined place.

In addition, when a change in the mounting position of the head 26 is required during product design, a change in the position of the insertion hole 30 and the screw hole 32 is required, and thus, a new production of the lower case 22 is required. With this demand, the production time is increased with the increase of the production cost.

SUMMARY OF THE INVENTION An object of the present invention for solving the above-listed problems is to provide a head position adjusting structure of a digital printing machine which allows the head to be positioned at a predetermined position even in the case of dimensional errors that may occur during design or manufacture.
