Coiled material flat screen silk-screen printing method and coiled material flat screen silk-screen printing machine

Abstract

The invention discloses a coiled material flat screen silk-screen printing method. The coiled material flat screen silk-screen printing method comprises the following steps that (1), a coiled material printed object is wound on a roller shaft assembly and uniformly moves forward with the speed v1, a screen frame uniformly and horizontally moves with the speed v2 in the same direction with printed object moving, the screen frame uniformly and vertically moves upward with the speed v3 along a guiding column, therefore the screen frame operates with the overall speed v4 in the inclined direction, and a scraper structure and the roller shaft assembly move uniformly and horizontally with the same speed as the screen frame and in the reverse direction with the screen frame; (2), when the screen frame and the coiled material printed object are in a relatively static state, the scraper structure moves downward to squeeze printing inks on the screen frame, and the printing inks leak onto the coiled material printed object through meshes; (3), after the screen frame and the scraper structure move oppositely and horizontally by a half length of a screen frame graph, one time of graphic printing is completed; and (4), the coiled material printed object continues to move uniformly, the screen frame, the scraper structure and the roller shaft assembly return to the initial positions, and the actions are repeated. The invention further discloses a coiled material flat screen silk-screen printing machine

Description

technical field [0001] The invention relates to the field of flat-screen screen printing machines for coil materials, in particular to a flat-screen screen printing method for coil materials and a flat-screen screen printing machine for coil materials. Background technique [0002] Flat-screen screen printing machine is a kind of equipment that squeezes the ink on the screen with a certain pressure by the squeegee, and the ink leaks to the substrate through the mesh of the graphic part on the screen. The flat screen screen printing machine has simple structure, cheap consumables, and convenient operation, and has been widely used in the markets of self-adhesive labels, electronic processing, printed circuit boards, and packaging materials. [0003] At present, there are two main structures of coil flat screen printing machines on the market: [0004] (1) The printing platform is flat, the screen is placed on the printing platform, the squeegee is on the screen, and the prin...

Problems solved by technology

With this structure, the screen frame and the roll material move together during silk screen printing, and the position of the printing cylinder is fixed, and it only rotates in a circle. After each image and text printing is completed, the roll material has to move a certain distance in the opposite direction, and the printing speed is not high. Low production efficiency

[0006] It can be seen from this that the existing coil flat screen screen printing machines on the market have slow running speed, low production efficiency, poor screen printing effect, and low productivity. With the daily fierce market competition and continuous improvement of screen printing process requirements, they will gradually withdraw. market
