Description

Technical Field

[0001] The invention belongs to the technical field of printing, and in particular relates to a carbon fiber magnetic quick-install closed scraper system. Background Art

[0002] Flexographic printing presses use highly fluid inks. The ink is transferred to the image and text part of the printing plate by the ink fountain rubber roller and the anilox roller, and then the pressure roller applies printing pressure to transfer the ink on the printing plate to the substrate. Finally, the printing process is completed after drying.

[0003] In the prior art, the Chinese utility model with application number: CN202122205485.6 discloses an all-carbon fiber scraper device, including a fixed crossbeam, a control airbag, a mounting cavity and a scraper blade. The utility model makes the fixed crossbeam, the mounting cavity, the connecting frame, the fixing frame and the scraper buckling plate out of carbon fiber material, so that the entire device is not easy to deform and corrode after long-term use, and it is also easy to clean and maintain the stained ink; by arranging a fixing plate and a hinge seat on the top of the fixed crossbeam, and the hinge seat and the connecting piece are movably connected by a hinge, the scraper blade can be better close to the ceramic anilox roller for scraping ink, so as to obtain a uniform ink layer and improve the ink hanging quality; the scraper blade is buckled and connected by the scraper buckling plate, and then fixed by an adjustable bolt. Compared with the prior art in which the scraper blade is directly fixed on the mounting cavity, this design can effectively prevent the scraper blade from deformation after long-term use;

[0004] When printing wide-format items, the printing device in the prior art usually uses a group of scrapers to scrape the anilox roller, which may cause uneven scraping of the anilox roller. When the printing speed is too fast, it may cause uneven printing and reduce the printing quality. The ink immersion area of ​​the anilox roller is open, which may cause ink splashing. Since the scraper is fixed with multiple groups of bolts, the efficiency of scraper replacement is reduced, which in turn increases the time for maintaining the equipment.

[0041] like Figure 2 As shown, the adjustment assembly 8 includes an adjustment bolt 83 threadedly connected to the other side of the casing 1, one end of the adjustment bolt 83 passes through the casing 1 and is rotatably connected to a mounting frame 81, a limiting roller 82 that fits the anilox roller 13 is rotatably connected inside the mounting frame 81, the mounting frame 81 is slidably arranged on both sides of the inner cavity of the casing 1, two groups of clamping rollers 9 are rotatably arranged in the inner cavity of the casing 1, a guide plate 10 located below the limiting roller 82 is fixedly connected to the inner cavity of the casing 1, the position of the mounting frame 81 is conveniently adjusted by using the adjustment bolt 83, so that the limiting roller 82 can press the printing paper against the anilox roller 13, and the clamping roller 9 can be used to quickly transport the printing paper, thereby improving the overall printing efficiency.

[0042] like Figure 3As shown, the material receiving assembly 15 includes a mounting plate 153 fixedly connected between the two groups of fixed plates 111 and a material box 151 arranged between the two groups of mounting plates 153. The opposite sides of the two groups of mounting plates 153 are provided with slots 154 for sliding and inserting the material supply box 151. A return valve tube 152 is provided on one side of the material box 151. The use of the material receiving assembly 15 effectively reduces the waste of ink.
