Water-based ink printing press capable of changing printing area

Abstract

The invention discloses a water-based ink printing press capable of changing printing area. The water-based ink printing press comprises a case body; the inner bottom wall of the case body is fixedly provided with a reference seat, and an automatic telescopic rod is fixedly installed in the reference seat; the telescopic end of the automatic telescopic rod is fixedly connected with a tool holding table; a driving motor is fixedly installed on the inner top wall of the case body; and the output end of the driving motor is fixedly connected with a rotating shaft. According to the water-based ink printing press capable of changing the printing area, in the rotating process of a printing mechanism, the power of the driving motor is controlled to increase to make the rotating speed increase, and accordingly, centrifugal force increases; print heads move outwards along base plane telescopic grooves under the action of the centrifugal force, and at this time, the centrifugal force is larger than the elastic force of the print heads to overcome the elastic force of springs, so that the printing area increases, so that larger to-be-printed matter can be conveniently printed, and on the contrary, if the power of the driving motor is reduced, the printing area is reduced; and the printing area is adjusted by the water-based ink printing press according to the specification of the to-be-printed matter, thus avoiding waste of electric energy.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a water-based ink printing machine capable of changing the printing area. Background technique [0002] A machine for printing text and images, a modern printing machine generally consists of mechanisms such as plate loading, ink application, embossing, and paper feeding. Its working principle is: first make the printing plate of the text and image to be printed, install it on the printing machine, and then apply the ink to the place where the text and image are on the printing plate manually or by the printing machine, and then transfer it directly or indirectly Printing onto paper or other substrate to reproduce the same print as the printing plate. [0003] However, the existing water-based ink printing machine cannot adjust the printing area during the printing process, which easily leads to incomplete printing, and is not suitable for printed materials of different specifi...

Problems solved by technology

[0003] However, the existing water-based ink printing machine cannot adjust the printing area during the printing process, which may easily lead to incomplete printing, and is not suitable for printed materials of different specifications, so its use has great limitations.
