Technical Field

The invention relates to the technical field of screen printing machines, in particular to a screen printing device with high printing quality.

Background

The screen printer, also called a screen printer, first makes the characters and images to be printed into a printing plate, installs the printing plate on the printer, then coats the ink on the positions of the printing plate where the characters and images are located, transfers the characters and images to the workpiece through a scraper component, and thus copies the same printed matter as the printing plate.

Traditionally, the screen printer comprises a driving mechanism for driving a stencil and a squeegee to move up and down; during silk-screen printing, a workpiece to be silk-screen printed is placed on the objective table, the driving mechanism drives the stencil printing plate to move downwards to press the surface of the workpiece to be silk-screen printed, and the ink scraping plate horizontally reciprocates to finish the silk-screen printing; and after silk printing, the driving mechanism returns to the original position upwards. And the process is circulated. In actual production, the following aspects affect the silk-screen quality:

1. if the residues on the surface of the silk-screen workpiece or dust and particulate matters generated in the transportation process are not removed in time before silk-screen printing, the silk-screen printing ink is not easy to smear and falls off;

2. for bottle-type silk-screen workpieces, the bottle-type silk-screen workpieces are usually not plugged during silk-screen printing, so that dust and particulate matters remain in the bottle, and the quality of the whole silk-screen product is not influenced, but the whole silk-screen finished product is adversely influenced;

3. for glass silk-screen workpieces, a fog layer is easily formed on the silk-screen surface in a low-room-temperature environment, and the existence of the fog layer affects the adhesion performance of ink and the quality of silk-screen;

4. for high-grade silk-screen printing pieces, high requirements are placed on the positions of silk-screen patterns, and high-precision positioning cannot be achieved by a traditional positioning mode.

Therefore, a high-printing-quality silk-screen device is urgently needed, which can improve the silk-screen quality of workpieces and the overall quality of the whole silk-screen finished product.
