Description

Technical Field

[0001] The invention relates to the fields of printing, transfer and nano pattern processing, and in particular to a production method based on pickled template processing. Background Art

[0002] At present, printing is divided into offset printing, gravure printing, flexographic printing, stencil printing, etc. These methods all use pickled stencils to print patterns. First of all, each color requires a set of printing units, and multiple colors require multiple sets of printing units and alignment detection units, so the equipment is expensive and bulky. Color overprint offset will also cause printing to be scrapped, and paper needs to be wasted to adjust the position accuracy of each printing unit. In addition, the ink is exposed to the air, causing volatilization and environmental pollution. Traditional transfer technology requires that the pattern be transferred to the workpiece through the transfer equipment after the printing pattern is on the film material, and there is no direct combination of the two machines for processing.

[0003] Therefore, it is necessary to provide a pattern processing method that is compact, moderately priced, odorless, and combines the advantages of printing and transfer. Summary of the invention

[0004] The present invention provides a method based on a pickled stencil transfer device, which adopts a closed ink transmission system to solve the problem of odor and environmental pollution; adopts a new printing + transfer technology for pattern processing to solve the problem of large equipment volume, and only requires one set of printing units for multi-color processing; adopts a new annular pickled stencil technology to solve the problem of color registration accuracy and automatic color registration processing.

[0005] In order to solve the above technical problems, the present invention provides a method based on a pickled stencil transfer device, comprising the following steps:

[0006] In the first aspect, the ink transfer adopted by the present invention is closed, the ink is transmitted to the liquid control system through a pipeline, and then the ink is accurately sprayed out through the CN115320233A inkjet head.

[0007] In the second aspect, before printing, the present invention arranges multiple patterns in a certain distance and order by plate-making equipment, and then uses laser welding to process them into an annular pickled template. During printing, the tension wheel drives the annular pickled template to rotate, and accurately outputs the overprint pattern to the transfer wheel.

[0008] Thirdly, the present invention adopts a coated transfer wheel or a rubber cloth transfer wheel cylindrical structure to receive the overprinted pattern - one pattern per rotation, and is matched with a dryer to dry the ink. After receiving the last layer of hot melt ink, it becomes sticky after drying, completing a cycle.

[0009] Fourthly, the present invention uses a circulating vacuum conveyor belt to drive the workpiece to move. After the transfer wheel completes a cycle, it drives the workpiece to combine with the transfer wheel once. Through the pressure and the release force on the transfer wheel, the pattern falls off the transfer wheel onto the workpiece, completing a cycle.

[0010] Fifthly, the present invention adopts a combination of cyclic gravure printing and transfer processing, which can shorten the length of a traditional gravure printing machine of more than ten meters to a few meters.

[0011] In a sixth aspect, the present invention adopts a combination of cyclic screen printing and transfer processing, and one machine can complete the work of several machines.

[0012] Seventhly, the present invention adopts a printing + transfer method, which is not liquid printing on the workpiece, but solid transfer to the workpiece, so more products are suitable for transfer.

[0013] In the eighth aspect, the present invention is equipped with a precise multi-pattern integrated pickling mold to achieve specific nano-printing transfer pattern processing. BRIEF DESCRIPTION OF THE DRAWINGS
