TECHNICAL FIELD

[0001] The utility model relates to a silk screen printing equipment technical field, especially relates to a silk screen printing machine's scraping device for ink. BACKGROUND

[0002] Silk screen printing refers to using silk screen as a plate base, and making a silk screen printing plate with graphics through a photosensitive method. Silk screen printing is composed of five elements, including a silk screen printing plate, a squeegee, ink, a printing table, and a printing substrate. It uses the basic principle that the graphic part of the silk screen printing plate can pass through ink, and the non-graphic part cannot pass through ink to print. During printing, ink is poured into one end of the silk screen printing plate, and the squeegee applies pressure to the ink part of the silk screen printing plate while moving at a constant speed towards the other end of the silk screen printing plate. The ink is squeezed from the graphic part of the screen by the squeegee onto the printing substrate.

[0023] In the present embodiment, as shown in Figure 1 , a squeegee device of a screen printing machine comprises a mounting frame 1, the inside of the mounting frame 1 is provided with a partition plate, the top end of the mounting frame 1 is provided with a squeegee cylinder 2 and a ink covering cylinder 10, the output end of the squeegee cylinder 2 is provided with a lifting support 3, both ends of the lifting support 3 are provided with mounting plates 4, the mounting plates 4 are provided with connecting rods 5, the connecting rods 5 are provided with squeegee holders 6, the bottom end of the squeegee holders 6 is provided with squeegees 7, the mounting plates 4 are provided with angle adjusting mechanisms 9, both ends of the connecting rods 5 are rotatably connected with the mounting plates 4, the bottom end of the ink covering cylinder 10 is provided with an ink covering mechanism 8, the ink covering mechanism 8 and the squeegees 7 are arranged on both sides of the partition plate.

[0024] In the present embodiment, both sides of the mounting frame 1 are provided with movable grooves 11, both ends of the connecting rods 5 pass through the movable grooves 11 and are connected with the angle adjusting mechanisms 9, both ends of the lifting support 3 are slidably connected with the movable grooves 11. When the squeegee cylinder 2 pushes the lifting support 3 to move towards each other, the lifting support 3 will slide in the movable grooves 11, so as to control the lifting action of the squeegees 7.

[0025] In the present embodiment, the main function of the ink covering mechanism 8 is to complete the ink covering action on the printing plate. As shown in Figure 2 and Figure 3 , the ink covering mechanism 8 comprises: an ink covering support 81 arranged at the bottom end of the ink covering cylinder 10, slide rails 82 arranged at both sides of the mounting frame 1, sliding blocks 83 arranged on the slide rails 82, ink covering knives 84 arranged at the bottom end of the ink covering support 81, and fixing pieces 85 arranged at both ends of the ink covering support 81.

[0026] Among them, both ends of the ink covering support 81 are provided with fixed grooves 811, the ink covering knives 84 are fixedly installed in the inside of the fixed grooves 811 through the fixing pieces 85.

[0027] In the present embodiment, the angle adjusting mechanism 9 is mainly used to adjust the angle of the squeegee 7 to adapt to the use conditions under different circumstances. As shown inFigure 4 as well as Figure 5 As shown, the angle adjustment mechanism 9 includes: an outer support base 91 mounted on the mounting plate 4, a movable toothed ring 92 mounted inside the outer support base 91, saw gears 93 mounted at both ends of the connecting rod 5, a spring 94 mounted inside the outer support base 91, and a retaining strip 95 mounted on the outer support base 91.

[0028] In this embodiment, one end of the movable toothed ring 92 is placed outside the outer support seat 91 and meshes with the saw gear 93; the other end of the movable toothed ring 92 is placed inside the outer support seat 91 and is slidably connected to the outer support seat 91. When it is necessary to adjust the angle of the scraper, the retaining strip 95 must be removed first, and then the movable toothed ring 92 is pushed to retract into the outer support seat 91, so that the movable toothed ring 92 is completely disengaged from the saw gear 93. At this time, the angle of the scraper 7 can be adjusted. After the adjustment is completed, the movable toothed ring 92 is released. Since the spring 94 inside the outer support seat 91 is compressed, its rebound force will push the movable toothed ring 92 to re-mesh with the saw gear 93, thereby fixing the connecting rod 5.

[0029] In this embodiment, as Figure 6 As shown, the top of the scraper holder 6 is provided with a fixing bolt 61, and the connecting rod 5 is fixedly installed on the top of the scraper holder 6 by the fixing bolt 61.
