Description

Technical Field

[0001] The utility model relates to the technical field of film printing, in particular to a screen printing device for film printing. Background Art

[0002] A screen printer works by applying a squeegee to the mesh, applying a pattern to the screen. The screen film is a specialized material used for printing. It's typically a transparent polyester film covered with a photosensitive coating. First, the design is digitally converted to a design. A printer then prints the design onto the screen film. The screen film and screen are placed in an exposure machine, where ultraviolet light is applied to the film, creating the image. The exposed film is then placed in a developer, where chemical reagents are used to develop the film, removing the coating from the unexposed areas and leaving the pattern. The developed film is then dried in a dryer. The screen film and screen are then placed in a printing press, where pressure forces ink into the product, creating the print.

[0003] However, when printing on existing films, a doctor blade and an ink return knife are usually used for scraping back and forth. However, the relative height of the doctor blade and the ink return knife is not easy to adjust, so that the ink will always remain between the doctor blade and the ink return knife, resulting in a shorter time for the ink to stay on the film, which reduces the printing efficiency. Utility Model Content

[0004] The utility model aims to provide a screen printing device for film printing, which has the advantage of adjusting the relative heights of a scraper and an ink return knife, and solves the problem of low film printing efficiency.

[0006] Preferably, two clamping mechanisms are symmetrically installed on the second telescopic mechanism, and the clamping mechanism includes a U-shaped frame, and the openings of the two U-shaped frames are both facing the frame. A long plate is installed in the U-shaped frame, and limiting rods are installed on both sides of the upper end surface of the long plate.

[0007] Preferably, the top ends of the two limiting rods extend out of the upper end surface of the U-shaped frame, and the limiting rods are slidably connected to the U-shaped frame.

[0008] Preferably, a threaded rod extending from the upper end surface of the U-shaped frame is installed in the middle of the long board, and a rotating handle is spirally connected to the outer edge surface of the threaded rod, and the rotating handle is rotationally connected to both the U-shaped frame and the long board.

[0009] Preferably, a rubber pad is installed at the bottom end of the U-shaped frame, and a plurality of first arc-shaped rubber lines are installed at equal intervals on the rubber pad. The plurality of first arc-shaped rubber lines are arranged in groups of two on the upper end surface of the rubber pad, and the long plate is installed with second arc-shaped rubber lines placed between the first arc-shaped rubber lines.

[0012] 1. The utility model is provided with a first lifting mechanism, a second lifting mechanism, a first connecting mechanism, a second connecting mechanism, a first scraper and a second scraper. The first lifting mechanism and the second lifting mechanism drive the first connecting mechanism and the second connecting mechanism to rise and fall. The first scraper and the second scraper at the bottom of the first connecting mechanism and the second connecting mechanism are used to perform scraping printing, thereby achieving the effect of adjusting the height of the scraper device. When the scraper is moved, the ink will not be immediately scraped away by the ink return knife, which increases the time that the ink stays on the film.

[0013] 2. The utility model is provided with a U-shaped frame, a long board, a limiting rod, a threaded rod, a rotating handle, a rubber pad, a first arc-shaped rubber line and a second arc-shaped rubber line.

The rubber pad and the long board in the U-shaped frame clamp the film, and the first arc-shaped rubber line and the second arc-shaped rubber line adhere to the surface of the film to increase the friction between the film and the long board.

[0014] 3. The utility model is provided with a load-bearing platform, a receiving platform and an adjusting mechanism. By adjusting the adjusting mechanism, the receiving platform is driven to move on the load-bearing platform, thereby adjusting the printing position. BRIEF DESCRIPTION OF THE DRAWINGS
