Description

[Detailed Description of the Invention] This invention relates to an automatic inking machine that applies ink while moving the ink in a circular manner to the rubbing surface of a rotating inkstone.

In the past, there were devices that used planetary gears to ink ink in order to obtain similar movements, but the structure was complicated and the mechanism required a large inkstone to use thick and large ink. There were some shortcomings.

This invention solves these problems using a simple mechanism.

To explain this with reference to the drawings, (a) Attach the inkstone 3 to the rotating shaft 2 of the drive motor 1.

(b) The starting shaft 5 driven by the drive belt 4 from the rotating shaft 2 passes through a bearing 6 to which an eccentric piece 7 is fixed.

(c) Attach the eccentric shaft 8 at a position offset from the rotation center of the eccentric piece 7 with the starting shaft 5 as the rotation center.

(d) A connecting shaft 9 having a hole that can freely rotate up and down is fitted onto the eccentric shaft 8, and an ink 11 is attached to a holder 10 at the tip of the shaft via a guide 12, and tightened with a screw 13.

With the above configuration, the eccentric shaft 8 attached to the eccentric piece 7 rotates around the starting shaft 5, and the fitted connecting shaft 9 transmits rotational motion to the holder 10 at the tip using the guide 12 as a fulcrum. The ink 11 attached to it moves in a circular motion on the wet surface of the rotating inkstone 3, and by attaching an appropriate weight to the holder 10, ink can be applied. Furthermore, the circle drawn by the ink 11 can be large or small depending on the position of the guide 12 serving as a fulcrum, so that the movement can be set to match the size of the inkstone 3.

Note that there are the following embodiments.

(b) The inkstone 3 does not rotate and the ink is inked only by the circular motion of the ink 11.

(b) A motor that drives the rotating shaft 2 that rotates the inkstone 3;
Equipped with a separate motor to drive the starting shaft 5.

Due to the structure described above, it is very easy to handle and attach ink, and since it moves in a smooth circular motion, it is possible to easily make high-quality ink liquid similar to that made by hand.

Claims (1)

[Scope of utility model registration request] In an automatic sanding machine in which an inkstone 3 attached to a rotating shaft 2 of a drive motor 1 rotates and an ink 11 attached to a holder 10 is also rotated by the rotating shaft 2, a starting shaft is connected to the rotating shaft 2 by a drive belt 4. The eccentric piece 7 fixed to the starting shaft 5 has an eccentric shaft 8 attached at a position offset from the position of the starting shaft 5, and the other end of the connecting shaft 9 is fitted to the eccentric shaft 8 so that the eccentric piece 7 can be rotated up and down at one end. An automatic blacking machine is provided with a holder 10 and a black marker 11 attached thereto, and a guide 12 serving as a fulcrum of the connecting shaft 9 is installed at an appropriate position on the connecting shaft 9.
