Positive and negative air pressure auxiliary printing head device

Abstract

The invention provides a device of a printing head assisted by positive and negative air pressure. The device comprises a negative pressure vacuum chamber, a printing ink chamber and a positive pressure chamber. Printing ink for traditional offset printing, intaglio printing, silk-screen printing, flexible plate printing and the like is manually added or transferred in a non-sealed mode, printing defects caused by reduction of the quality of the printing ink are often caused, and the printing ink volatilizes to pollute the environment. When a CN115320233A ink jet head is used for transferring ink, micropores in a pickling template in a fine pattern can be incompletely filled, and the printing quality is influenced; according to the device, gas in micropores in the pickling template is exhausted through negative air pressure, then ink is driven to be filled through the scraper, finally, positive air pressure assists the ink to be separated from the pickling template, and the precise printing requirement is met.

Description

Technical Field

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

[0002] At present, printing is divided into offset printing, gravure printing, flexographic printing, stencil printing, etc. These methods all use pickled stencil printing processing methods, and the ink is exposed to air pressure, causing volatilization and environmental pollution. With the improvement of precision printing and environmental requirements, when using CN115320233A inkjet head to print precision products, it is difficult for the ink to perfectly fill the tiny micropores of the pickled stencil, which easily causes poor printing.

[0003] Therefore, it is necessary to provide an inkjet head suitable for precision printing. Summary of the invention

[0004] The present invention provides a device for assisting a printing head with positive and negative air pressures, adopting sealed ink transmission; adopting negative pressure vacuum pre-treatment, the negative pressure is very helpful for plugging and filling micropores with ink, especially since the ink used for printing is generally highly viscous; adopting a scraper at a certain angle to scrape the ink and fill the pores of the pickled template; adopting positive pressure air pressure post-treatment, the positive pressure is very helpful for the exhaust, compaction and demolding of high-precision electrode printing and solder paste printing.

[0005] In order to solve the above technical problems, the present invention provides a device for assisting a printing head with positive and negative air pressure, comprising the following steps:

[0006] In the first aspect, the ink transfer adopted by the present invention is closed, and the ink pipeline joint is directly connected to the present invention, and the ink is evenly and quantitatively filled into the ink chamber through the flow channel in the present invention.

[0007] Secondly, the present invention forms an ink chamber by using a scraper + a flow channel sheet at a certain angle in the front and rear, which can print not only forward but also backward.

[0008] In the third aspect, the present invention processes an air pressure chamber in front of and behind the ink chamber by combining a scraper baffle, a flow sheet, and an air inlet / outlet; and forms a positive or negative pressure in the air pressure chamber by changing the state of the positive and negative pressure solenoid valves by a machine.

[0009] In a fourth aspect, the present invention prints inks of different colors or types through different ink inlet holes, thereby realizing a multi-purpose printing head. BRIEF DESCRIPTION OF THE DRAWINGS
