Description

Technical Field

[0001] The utility model relates to the technical field of composite film-tearing and dust-removing mechanisms, in particular to a composite film-tearing and dust-removing mechanism for a sheet-to-roll silk-screen printing all-in-one machine. Background Art

[0002] Silk screen printing belongs to the orifice printing of the four major printing techniques (letterpress printing, gravure printing, lithography, orifice printing). The mesh holes of the image and text part can pass through the ink and leak onto the substrate, while the rest of the printing plate is blocked and cannot pass through the ink, forming a blank on the substrate. Silk screen printing is to weave silk, synthetic fiber or metal wire into a mesh, stretch it tightly on the screen frame, and use manual film engraving or photochemical plate making methods to make a screen. Only the image and text part of the screen can pass through the ink, while the mesh holes of the non-image and text part are all blocked and cannot pass through the ink. Commonly used silk screen printing machines are mostly sheet-to-roll silk screen printing all-in-one machines.

[0003] When the sheet-to-roll screen printing machine is in use, the substrate is usually coated with a dust-proof film before printing. The dust-proof film needs to be removed during printing before screen printing. However, the commonly used sheet-to-roll screen printing machine does not remove dust when tearing the film. When the substrate is being transported, dust will fall on the top of the dust-proof film. When tearing the film, the dust will float around the film tearing mechanism and then fall on the top of the substrate, causing defects and other problems during subsequent printing.
