Description

Technical Field

[0001] The utility model specifically relates to the technical field of scraping and cleaning a silk screen screen, in particular to a scraping and cleaning structure for a silk screen screen after printing. Background Art

[0002] The squeegee used in screen printing is also called a scraper or scraper. It is an important tool for screen printing. The squeegee used in printing can be divided into printing squeegee and ink return squeegee. The function of the screen printing squeegee is to squeeze the ink through the opening of the screen printing plate of the screen printing machine and transfer it to the surface of the substrate.

[0003] After printing, traditional silk screen printing screens will have ink residue on the printing plate. When printing again, the residual ink on the printing plate will affect the printing, which greatly reduces the working efficiency of the printing equipment. Traditional printing devices do not have a special structure for scraping and cleaning the silk screen screens, and most of them use manual scraping, which has low working efficiency.

[0004] After searching, Chinese patent publication number CN202022538147.X discloses a scraper structure of a screen printing machine; it includes a scraper sleeve, the scraper sleeve is plugged and connected inside, push plates are provided on both sides of the scraper, the push plates are rotatably connected to the inside of the scraper sleeve, a fixed cylinder is fixedly connected to the top of the scraper, a spring is provided inside the fixed cylinder, a telescopic end is fixedly connected to the top of the spring, a first fixed plate is provided on the top of the telescopic end, the scraper can be clamped by the provided scraper sleeve, the scraper can be retracted into the scraper sleeve by starting the first electric push rod, and the ink solidified on the scraper surface can be scraped off when the scraper is retracted into the scraper sleeve by the provided push plate;

[0005] The structure in the above patent uses a scraper to scrape the ink during printing, so that the ink is evenly scraped onto the screen printing screen. After the scraping is completed, the ink on the screen printing screen cannot be effectively cleaned, so that the ink remaining on the screen printing screen will affect the printing during the next printing, resulting in color bleeding or incomplete printing.

[0006] In view of the above situation, we provide a scraping and cleaning structure after silk screen printing. In this device, after the printing roller completes printing on the silk screen and the workpiece on the printing table, the movable plate installed on the printing table is pulled by the push frame. When the movable plate moves, the teeth on the movable plate mesh with the gears, and the gears drive the tooth plate to move, so that the connecting frame installed with the tooth plate and the scraper can move along the second slide rail. When the connecting frame moves, the scraper can effectively move along the surface of the silk screen. In the process of movement, the scraper can effectively scrape and clean the ink remaining on the surface of the silk screen. Utility Model Content
