Multi-color-process curved printing machine provided with flat type screen plate

Abstract

The invention relates to a multi-color-process curved printing machine provided with a flat type screen plate. The multi-color-process curved printing machine is characterized by comprising a printingstation, curved table plate components, a table plate track driving mechanism, a screen plate follow-up driving mechanism, a mold roller rotation driving mechanism and a mold roller angle locking mechanism, wherein the printing station comprises the flat type screen plate; each curved table plate component is used for supporting a printed material; the table plate track driving mechanism is connected with all curved table plate components and is used for driving each curved table plate component to do cyclic horizontal movement according to a closed track; the screen plate follow-up driving mechanism is used for driving each float type screen plate to synchronously and horizontally move; the mold roller rotation driving mechanism is used for driving all curved table plate components positioned on the corresponding printing stations to rotate synchronously; and the mold roller rotation driving mechanism comprises a clutching driving component which is used for driving the mold roller rotation driving mechanism to leave away from or approach to a rotating shaft to realize torque transmission or release. The multi-color-process curved printing machine provided by the invention has the advantages of realizing rotation of the rotating shaft by adopting a centralized synchronous driving way and also preventing a movement interference problem of a rotating shaft driving mechanism, thereby smoothly realizing multi-color-process high-precision printing on an elliptic screen printing machine.

Description

technical field [0001] The invention relates to a multicolor printing machine, in particular to a multicolor flat screen curved surface printing machine. Background technique [0002] Curved printing refers to the general term of printing methods for printing substrates with curved surfaces. According to the different development stages of curved surface printing, curved surface color printing is divided into traditional methods and modern methods. There are several types of printing, pad printing and letterpress offset printing of formed objects. Modern methods are divided into 3D color printing, rotating body surface inkjet printing and three-dimensional inkjet printing methods according to the different spatial motion forms of the substrate. [0003] In terms of curved screen equipment technology, due to the low price of screen printing equipment, long history of use, and relatively mature related facilities, it still has certain competitiveness and market prospects compa...

Problems solved by technology

[0008] As we all know, in multi-color printing, the mold roller supporting the substrate not only needs to rotate to realize curved surface printing, but also needs to be able to move through multiple screen printing stations in sequence on the same plane according to a circular or elliptical trajectory. The screen is used for color registration. If the current substrate and mold roller move to the bottom of each screen for printing, the change of the reference position of the substrate on the mold roller and the screen on each corresponding station exceeds the required error range, then It will cause the problem of inaccurate color registr
