Description
Technical Field
The utility model relates to the technical field of screen printers, in particular to a screen printing device for batch printing, which can prevent ink from dripping downwards from meshes of an image-text part in the ink returning process of a scraping and printing scraper so as to influence the printing effect.
Background
The screen printer uses the principle that the mesh of the image-text part of the screen printing plate is permeable to ink and the mesh of the non-image-text part is impermeable to ink, and the ink is poured into one end of the screen printing plate during printing, and then the ink is extruded onto a printing stock from the mesh of the image-text part by a scraping scraper, so that the printing of a product is completed. In order to ensure that the printing ink on the next product is sufficient, the previous product is usually taken out after the printing on the previous product is finished, the scraping blade is returned to the initial position, and the excessive ink is scraped back to the initial position in the process that the scraping blade is returned to the initial position.
However, in the process that the scraping scraper returns to the initial position, as the meshes of the image-text part of the screen printing plate are penetrated by ink, the excessive ink can drop downwards from the meshes, so that the ink quantity of a subsequent printing product is thicker than that of the previous product or the ink quantity of each mesh drop is inconsistent, the ink coverage is uneven, and even the dropped ink can be scraped on the edge of a target pattern, thereby affecting the printing quality of the product. Especially in batch printing line operations, the dripping ink can easily cause uneven printing effect of the same batch of products.
In order to obtain better printing quality, a silk screen printing machine with even oil coating is disclosed in patent application No. CN217415191U, and through uniformly arranging a diversion hole and a diversion pipe at one end of the ink scraping part close to the screen plate, ink is uniformly provided for the ink scraping part, so that the ink scraping part can uniformly coat oil when printing a product. There is still the problem of ink dripping down from the mesh of the image portion, affecting the quality of subsequent printing.
Based on the above problems, improvements are needed to be made on existing screen printers to obtain printing devices for batch printing that can avoid ink dripping down from the mesh of the graphics part, which would affect the print quality of the subsequent product.
