Mechanism for controlling ink of roller stamping machine

Abstract

The invention relates to a mechanism for controlling ink of a roller stamping machine. An ink box mechanism comprises an ink box base; a sponge wheel, a printing pad, sponge oil adsorption pillars and a printing pad spring are arranged in the ink box base; the printing pad is supported in the ink box base by the printing pad spring; at least one sponge oil adsorption pillar is arranged between the printing pad and the bottom of the ink box base; the upper part of the ink box base is provided with an opening; the sponge wheel is arranged on the opening by a rebounding device, so that the sponge wheel is in contact with the printing pad under the action of the pressure and is rebounded and returned after the pressure is relieved; the position on a paper pickup roller shaft of a paper pickup roller mechanism, which is above the sponge wheel, is fixedly provided with a stamp wheel; the stamp wheel comprises a convex surface and a concave surface; a stamp of the stamp wheel is arranged on the convex surface; and when the paper pickup roller shaft drives the stamp wheel to rotate, the convex surface of the stamp wheel presses down the sponge wheel, so that the sponge wheel is pressed down to be in contact with the printing pad and is pressed up to be in contact with a paper feeding rubber wheel. The mechanism has a simple structure; when the mechanism continuously feeds ink and continuously works for a long time, ink is uniform; and the stamp is integrated and is not deformed.

Description

technical field [0001] The invention relates to a mechanism for ink control of a roller stamping machine. Background technique [0002] At present, most of the ink filling and ink volume control of the automatic roller stamping machines on the market use the sponge wheel to take out the ink from the ink cartridge to supply ink to the stamp. Improper operation by the user, such as continuously adding ink to the ink cartridge in violation of regulations or continuous operation of the machine for a long time will cause the oil content of the sponge wheel to be too high, resulting in too much stamp ink or local ink accumulation. The purpose of this mechanism is to design a mechanism that can overcome the ink control when the user continuously adds ink and the machine works continuously for a long time. Contents of the invention [0003] The object of the present invention is to provide a mechanism for controlling the ink of the roller stamping machine with simple structure, c...

AI Technical Summary

Problems solved by technology

Improper operation by the user, such as continuous refilling of ink cartridges in violation of regulations or continuous operation of the machine for a long time will cause the oil content of the sponge wheel to be too high, resulting in excessive stamp ink or partial accumulation of ink, etc.
