Description

[Detailed Description of the Invention] The present invention relates to an improvement of a printing ink spreading device on a rotating disk, and particularly relates to a new printing ink spreading device that can stably obtain a thin layer of new ink. It is something.

Conventionally, when stamping characters or the like on non-hygroscopic objects, it is common to spread quick-drying, moderately viscous ink onto a flat plate with a roller, and then manually apply the spread ink to the desired object using a rubber stamp or the like. It was stamped.

However, when the ink is spread manually using a roller, it is difficult to maintain a constant ink thickness, and when stamping is done manually, a rubber stamp is pressed once on the spread ink. There is a concern that the stamp may be applied redundantly, such as applying the stamp again to the area where it was applied and then applying it again for the next stamp.

Therefore, if a stamp is made in such a state, there is a risk that the stamped characters will be cut off because the amount of ink that adheres to that part is small or it does not adhere to that part.Furthermore, since the ink dries quickly, it is likely to harden, resulting in unreliable results. Economically, work efficiency is poor.

Moreover, there were problems such as the need for skill.

This invention 14. This method was developed to solve the above-mentioned problems, and focused on mechanically spreading ink etc. into a film.

Briefly stated, the present invention includes a rotating disk, an ink stretching block that stretches ink placed on the disk by forming a minute gap and is equipped with a pressure spring, and a pressure spring that stretches the ink. A block for removing ink on the disk stretched by the stretching block is arranged concentrically with a predetermined distance apart.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the sealing ink spreading device according to the present invention will be described in detail with reference to the drawings.

In the first chest, a is a plan view and b is a cross-sectional view for explaining one embodiment of the present invention, 1 is a rotating disk rotated by a drive shaft 11, and 2 forms a desired minute gasof 21. 3 is a block for removing the ink remaining on the surface of the rotating disk after it has been attached to a rubber stamp (not shown); 4 is an ink spreading block having steps for contacting the surface of the rotating disk on both sides; A spring presses the stretched flock 2 and the residual ink removal block 3 against the surface of the rotating disk, 5 is the ink placed on the rotating disk, and 51 is a thin layer of ink stretched on the surface of the rotating disk. be.

For such a configuration, an ink stretching block 2 provided with a pressure spring 4 and a residual ink removing block 3 are mounted on a rotating disk 1 integrally constructed with a drive shaft 11 rotated by a drive source (not shown). The ink 5 is then placed on the front surface of the ink stretching block 2 and on the surface of the rotating disk 1, and the rotating disk 1 is moved in the direction of the arrow. When rotated in direction A, the ink 5 placed on the rotating disk 1 is pushed by the ink stretching flock 2, and enters the minute gap 21 of the ink stretching flock 2, so that the ink 5 placed on the rotating disk 1 is pushed into the rotating circle. The pressure adheres onto the surface of the plate 1, and as the rotating disk 1 rotates, a thin ink layer 51 with a width and thickness defined by the gap 21 is formed on the plate surface.

The ink 5 placement portion of the ink stretching flock 2 placed on the front side in the rotational direction of the rotating disk 1 has a concave shape as is clear from the plan view a, so that the ink 5 stored in this portion has a concave shape. Instead of spreading to the sides of the block 2 and flowing out, an appropriate amount enters the retention orifice and minute gap 21 one after another.

In this manner, the stamp surface of a rubber stamp (not shown) is pressed against the thin ink film 51 to cause the ink to adhere, thereby stamping a predetermined object.

By the way, since the ink dries quickly, it solidifies after a predetermined period of time and therefore does not adhere to the rubber stamp.

The residual ink 52 that has solidified or does not adhere to the rubber is removed by scraping the surface of the rotating disk 1 with the residual ink removal block 3.

Therefore, continuous or intermittent operation can be performed freely depending on the content of the work, and furthermore, the thin ink film 51 is always in a state suitable for stamping so that the stamping work can be performed.

FIG. 2 is a side view for explaining an embodiment of automatic stamping to which the ink spreading device for stamping according to the present invention is applied, and parts equivalent to those in the previous figure are denoted by the same reference numerals.

Reference numeral 6 is a gusset provided with a holding portion 61 for the rubber stamp 7 via a telescoping shaft 62, and 8 is an object to be stamped.

As shown in the figure, a predetermined amount of ink is placed on the front surface of the ink stretching flock 2 placed on the rotating disk 1 in the direction of rotation, and the rotating disk 1 is moved in the direction of arrow A to correspond to the printing speed. When the ink 5 is moved, the ink 5 fills the minute gap 21 formed in the ink stretching flock 2, as described above.
As in the previous figure, a thin ink layer 51 defined by 1 is formed on the surface of the rotating disk.

With the thin ink layer 51 formed on the rotary disk 1 in this way, the holding part 62 of the rubber stamp 7 provided on the machine 6
When is moved in the direction of arrow B-B, the thin ink layer 51 adheres to the surface of the rubber stamp 7, so that the holding portion 6 of the rubber stamp 7
2 is moved in the direction of arrow C by extending the telescopic shaft 62, once stopped on the object 8 to be stamped, and then moved in the direction of the arrow to stamp.

By rotating the rotary disk 1 in accordance with the time required for this stamping operation, the thin ink layer 51 is prevented from being located at the same location on the rubber stamp 7, so that the optimal thin layer of stamping is always achieved. I can do it so that I can get it.

Stamping is automatically repeated as described above, but as the rotary disc 10 rotates, the remaining ink layer 51 on the rubber stamp attached to the rubber stamp is removed by the residual ink removal block 3.
It is removed 52 at .

Although we have described in detail the embodiment of the ink spreading device for stamping of the present invention that automates the stamping work, it is also possible to perform only the stamping work manually, but in this case, it is necessary to obtain a uniform and always optimal thin layer of ink. As a result, the operator can concentrate only on stamping and is freed from the work of spreading ink.

As is clear from the above explanation, according to the present invention, it is possible to form a thin ink film with the same thickness and in a state suitable for stamping at all times, so it is expected to improve work efficiency and improve the quality of stamping. Dogs contribute to the improvement of
