Description

Reinforced sandwich oblique-angle frictioning strip

Technical Field

The utility model relates to a screen printing technical field, concretely relates to adhesive tape is scraped to strenghthened type sandwich oblique angle.

Background

The silk-screen printing is composed of five major elements, namely a silk-screen printing plate, scraping glue, printing ink, a printing table and a printing stock. The basic principle that the meshes of the image-text part and the non-image-text part of the screen printing plate are permeable to ink and impermeable to ink is utilized to print.

The squeegee is a glue strip used in the screen printing process and is generally also called glue squeegee. The frictioning with different hardness and different section shapes can be selected according to the characteristics of the printing stock of the silk-screen printing, the precision requirement of the printing pattern and the difference of the printing modes; when printing, ink is poured into one end of the screen printing plate, a certain pressure is applied to the ink position on the screen printing plate by using frictioning, meanwhile, the ink moves towards the other end of the screen printing plate at a constant speed, and the ink is extruded onto a printing stock from meshes of the image-text part by frictioning in the moving process; the frictioning always presents line contact with the silk screen printing plate and the printing stock in the printing process, and the contact line moves along with the frictioning movement.

The softer the colloid of the scraping adhesive tape, the tighter the contact with the printing ink is, so that the removal of the redundant printing ink on the screen printing plate is facilitated; however, the deformation degree of the scraping strip in the construction process is influenced by the fact that the scraping strip is soft, and the phenomenon of uneven printing ink is caused; in addition, the existing scraping rubber strips are often in straight angles, so that the line contact between the scraping rubber strips and the screen printing plate and the printing stock is not always ensured, and the lines are not flat; and the upper end of the existing adhesive scraping strip often needs to be provided with a handle for a worker to hold, but the adhesive scraping strip is not easy to be fixedly connected with the handle due to the flat surface.
