Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to a scraper assembly of a printing machine. Background Art

[0002] A printing press is a machine for printing text and images. It is generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding. The text and image to be printed are first made into a printing plate and mounted on a printing press. Ink is then applied to the areas on the printing plate where there are text and images, either manually or by a printing press, and then directly or indirectly transferred to paper or other substrates, thereby reproducing a printed product identical to the printing plate.

[0003] With the development of science and technology and the progress of society, the types and functions of printing machines are becoming more and more perfect. For example, the model WJPS-350D offset intermittent rotary printing machine is composed of a feeder, a printing unit, a cold stamping unit, a flexographic printing unit, a circular die-cutting machine and a winder. In the printing unit, a scraper assembly is needed to wash the ink of the inking roller. In actual use, bolts are generally used to fix the ink-washing scraper. Due to the small size of the ink-washing scraper, it is not easy to operate when fixed with bolts, which may easily cause the operator to be scratched by the scraper.

[0035] A fixing mechanism 4, the fixing mechanism 4 is arranged inside the ink washing tank 3;

[0036] A rotating mechanism 5, wherein the rotating mechanism 5 is arranged outside the ink washing tank 3;

[0037] The fixing mechanism 4 includes a positioning groove 401, which is opened at the bottom of the front end of the ink washing tank 3, and the inside of the positioning groove 401 is movably sleeved with an ink washing scraper 402, and the left and right ends of the inside of the positioning groove 401 are movably sleeved with a pressing block 403, the number of the pressing blocks 403 is two, and the back surfaces of the two pressing blocks 403 are respectively fixedly installed with short rods 404, the number of the short rods 404 is two, and the bottoms of the opposite surfaces of the two short rods 404 are respectively fixedly installed with long rods 405 There are two long rods 405, and the insides of the two long rods 405 are movably connected with limit blocks 406 respectively. The top of the limit block 406 is fixedly connected to the outer surface of the ink washing tank 3, and the tops of the two long rods 405 are movably connected to the bottom end of the ink washing tank 3. The rear ends of the two long rods 405 are hinged with inclined rods 407 respectively. There are two inclined rods 407, and the tops of the two inclined rods 407 are movably connected to the bottom end of the ink washing tank 3. The inclined rods 407 will cause the pressing block 403 to move.

[0038] When the rear ends of the two inclined rods 407 move backward, the front ends of the inclined rods 407 will generate a pulling force on the long rods 405, pulling the two long rods 405 to move toward each other along the outer surface of the limit block 406, so that the short rod 404 fixedly connected to the long rods 405 moves along the inner surface of the positioning groove 401 with the pressure block 403. Since the top of the pressure block 403 is an inclined surface, as the pressure block 403 moves, a pressure will be generated on the bottom end of the ink washing scraper 402, thereby pressing the ink washing scraper 402 to prevent the ink washing scraper 402 from moving, thereby facilitating the installation and disassembly of the ink washing scraper 402.

[0039] Wherein, the rotating mechanism 5 comprises:

[0040] A support block 501, which is fixedly mounted on the top of the middle of the front end of the ink washing tank 3, and a threaded rod 502 is movably sleeved inside the support block 501;

[0047] When the pressure regulating bolt 10 is rotated, the pressure regulating bolt 10 can be moved along the inner surface of the locking block 9, thereby adjusting the pressure between the ink washing scraper 402 and the ink stringing roller.

[0048] Among them, a cleaning plate 11 is movably sleeved at the rear end of the ink washing tank 3, a mounting rod 12 is fixedly installed on the top of the cleaning plate 11, the right side of the bottom end of the mounting rod 12 is movably connected to the top of the ink washing tank 3, a second handle 13 is fixedly installed in the middle of the top of the mounting rod 12, a fixing plate 14 is movably sleeved on the right side of the outer surface of the mounting rod 12, the bottom end of the fixing plate 14 is fixedly connected to the top of the ink washing tank 3, and the second handle 13 will drive the cleaning plate 11 to move.

[0049] When the second handle 13 is pushed, the mounting rod 12 will move along the inner surface of the fixing plate 14 , thereby causing the cleaning plate 11 to move along the inner surface of the ink washing tank 3 .

[0050] A slot 15 is provided on the right side of the top end of the mounting rod 12 , and a block 16 is movably sleeved inside the slot 15 . The top end of the block 16 penetrates the fixing plate 14 and extends to the outside of the fixing plate 14 .

[0051] The presence of the locking slot 15 and the locking block 16 will lock the position of the mounting rod 12 .

[0052] Among them, the top of the clamping block 16 is movably sleeved with a limit plate 17, and the limit plate 17 is fixedly sleeved inside the fixed plate 14. The top of the clamping block 16 is fixedly installed with a circular plate 18, and the bottom end of the circular plate 18 is fixedly installed with a spring 19, and the other end of the spring 19 is fixedly installed on the top of the fixed plate 14.

[0054] The working principle and use process of this utility model:

[0055] First, when installing the ink scraper 402, the operator first inserts the ink scraper 402 into the positioning groove 401, and then turns the first handle 503 to rotate the threaded rod 502. At this time, the movable block 504 threadedly connected to the threaded rod 502 will move downward with the bottom end of the inclined rod 407, so that the top end of the inclined rod 407 produces a pulling force on the long rod 405, pulling the two long rods 405 to move toward each other along the outer surface of the limit block 406, so that the pressing block 403 moves along the inner surface of the positioning groove 401 with the long rod 405 through the short rod 404. Since the end of the pressing block 403 facing the ink scraper 402 is an inclined surface, as the pressing block 403 moves, a pressure will be generated on the ink scraper 402, thereby fixing the ink scraper 402, thereby improving the convenience of installing and disassembling the ink scraper 402.

[0056] After the ink washing scraper 402 is installed, the operator can turn the pressure regulating bolt 10 to make the slider 7 move with the ink washing tank 3 and the ink washing scraper 402 along the inner surface of the long groove 6 toward the ink roller, so as to adjust the pressure between the ink washing scraper 402 and the ink roller through the pressure regulating bolt 10, thereby adjusting the cleaning force of the outer surface of the ink roller. As the ink roller rotates, the ink and solvent on the outer surface of the ink roller will be scraped into the ink tank 3 by the ink washing scraper 402. When cleaning the substances inside the ink washing tank 3, in order to ensure The inner wall of the ink tank 3 is cleaned thoroughly, and the operator pulls the circular plate 18, so that the circular plate 18 moves upward along the outer surface of the limit plate 17 with the block 16 and stretches the spring 19 until the block 16 and the slot 15 are separated, releasing the lock of the block 16 on the position of the mounting rod 12. Then the operator pushes the second handle 13, so that the second handle 13 moves along the inner surface of the ink washing tank 3 with the cleaning plate 11 through the mounting rod 12, thereby scraping off the residual material on the inner wall of the ink washing tank 3, thereby improving the convenience of cleaning the ink washing tank 3.

[0057] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
