Ink path system used based on pickling template printing

Abstract

The invention provides an ink path system used based on pickling template printing. The ink path system comprises an ink circulating system, an ink pressure input and output system and a nozzle cleaning system. At present, an ink system based on a pickling template printing process for offset printing, intaglio printing, flexographic printing, silk-screen printing and the like is used for simply extracting and adding ink, and is not environment-friendly or intelligent. When a CN115320233A ink jet head is matched with the ink jet printer, the ink jet printer has the following advantages: 1, ink is directly conveyed to the ink jet head through a pipeline, and the whole process is in a closed state, so that the ink jet printer is environment-friendly and does not volatilize; 2, by matching with a viscosity detector, the ink and the solvent can be fully automatically mixed to reach a required viscosity value; and 3, the printing ink flow can be accurately controlled through sectional type printing ink pressure output. And 4, a matched cleaning system is more intelligent.

Description

Technical Field

[0001] The invention relates to the field of printing and transfer processing, and in particular to a production method based on pickling stencil processing. Background Art

[0002] At present, printing is divided into offset printing, gravure printing, flexographic printing, stencil printing, transfer printing, etc. These methods are all produced by pickled stencil printing. Most of the ink is exposed to the outside, which is easy to cause environmental pollution. The CN115320233A inkjet head is used to replace the traditional scraper to seal the ink transmission, which requires a suitable ink path system to match. In order to accurately fill the grooves and pores on the pickled stencil, the transmission pressure needs to be precisely controlled. Too much pressure will cause ink waste, and too little pressure will cause incomplete ink filling patterns. Because pickled stencil printing is a high-speed printing, the ink path system needs to be quickly switched on and off and conveniently cleaned automatically.

[0003] Therefore, it is necessary to provide an ink system suitable for pickled stencil printing and transfer: closed ink transmission, fast start and stop ink transmission, stable pressure delivery, intelligent cleaning and maintenance, and intelligent ink viscosity adjustment. Summary of the invention

[0004] The present invention provides an ink path system based on pickled stencil printing, which uses compressed air as a driving force to output ink directly to the inkjet head to start working. Although the structure is simple and the cost is low, due to the friction between the ink and the pipeline, the pressure is lost after passing through other devices, making it difficult to control the output pressure and difficult to quickly respond to the switch demand. The viscosity modulation of the ink, the cleaning of the pickled stencil, the nozzle, and the pipeline are all areas that need to keep up with automation.

[0005] In order to solve the above technical problems, the present invention provides an ink path system based on pickled stencil printing, comprising the following steps:

[0006] In the first aspect, in order to ensure the stability of the ink pressure and the rapid switching control, the present invention designs a segmented ink transmission: the ink transmission control circuit (21) transmits the pressure of the compressed air (1) to the mixing ink cartridge (10) through the air pipe, drives the ink in the mixing ink cartridge (10) to be transmitted to the switching solenoid valve (14) through the liquid pipe, and then transmits it to the pressure switch valve (3) through the liquid pipe; the ink output control circuit (22) transmits the pressure of the compressed air (1) to the gas valve controller (3) through the air pipe, the gas valve controller (3) controls the pressure switch valve (3) by adjusting the gas pressure, controls the ink flow pressure and flow by adjusting the pressure switch valve (3), transmits the ink to the inkjet head (4), and the ink flows out through the inkjet head (4).

[0007] In the second aspect, the ink circuit system of the present invention is designed as follows: the ink cleaning control circuit (23) transmits the pressure of the compressed air (1) to the cleaning liquid box (13) through the air pipe, drives the liquid in the cleaning liquid box (13) to be transmitted to the switching electromagnetic valve (14) through the liquid pipe, and then transmitted to the pressure switch valve (3) through the liquid pipe, and then to the inkjet head (4), and then to the electromagnetic valve (5), and then to the waste ink box.

[0008] 10. In the third aspect, the ink circuit system of the present invention is designed as follows: the ink modulation control circuit (24) detects whether the ink in the mixing ink cartridge (10) activates the solenoid valve (5) to open / close through the liquid level detector (8); detects whether the ink in the liquid tube activates the solenoid valve (5) to open / close through the ink viscosity detector (12), adds solvent to the mixing ink cartridge (10), and starts / closes the ink agitator (7).
