Description

Technical Field

[0001] The utility model relates to the technical field of roll material printing, in particular to a roll material PS plate printing device. Background Art

[0002] As an important printing equipment, the printing press is widely used in the printing industry and publishing industry. It is a mechanical equipment that can realize large-scale printing. It can print text, graphics, images and other contents on paper or other materials in an efficient and accurate manner. The PS plate printing press is the most common printing equipment, which is mostly suitable for printing roll materials. The existing PS plate printing press adopts digital exposure technology to transfer the image to the PS plate through a laser printer. Subsequently, the developer is injected into the plate through the plate surface liquid path system to make the image part ink-receptive and the non-image part water-receptive. Then, the fountain solution is injected into the plate surface to form a water film on the non-image part and the image part water-receptive. Ink, then, the plate is mounted on the plate cylinder. When printing, the ink flows out from under the ink cartridge, and after being evenly spread by a series of ink-distributing rollers, the ink-distributing roller applies the ink to the image part of the plate. When the plate contacts the rubber-coated roller, the ink sticks to the surface of the rubber-coated roller, and the rubber-coated roller transfers the ink to the paper by rotation to complete the printing work. When the traditional PS plate printing machine is working, the single ink filling tube fills the ink, and the ink cannot be evenly injected into the ink cartridge, which will cause the ink-distributing roller to distribute the ink unevenly, affecting the printing quality. After working for a period of time, the ink on the edge of the ink cartridge will adhere to or even condense on the inner wall of the ink cartridge, affecting the ink feeding speed. For this reason, we propose a roll material PS plate printing equipment. Utility Model Content

[0025] The working principle of a roll material PS plate printing device provided by the utility model is as follows: when printing, the processed PS plate is installed on the surface of the plate cylinder 483, and the roll printing material is installed on the installation roller 5, so that the printing material passes between the two rubber-coated cylinders 484, and the single-chip microcomputer 3 controls the right-angle motor 49 to operate. The output shaft of the right-angle motor 49 drives the screw rod 41 to rotate forward, and the slider 42 moves forward. Because the gear 44 located on the same side is meshed and connected with the rack plate 45, the gear 44 will rotate with the forward movement of the slider 42, driving the stirring frame 43 to rotate. The stirring frame 43 and the stirring rod stir the ink inside the ink cartridge 2 to prevent the ink from condensing. As the stirring frame 43 rotates, the rubber scraper 46 also rotates accordingly. The rubber scraper 46 scrapes off the ink attached to the inner wall of the ink cartridge 2. At the same time, the ink is injected into the ink cartridge 2 through the ink injection tube 47. When the ink is injected, it is just stirred and spread evenly by the stirring frame 43 and the stirring rod. The slider 42 moving along the direction of the ink cartridge 2 can also make the ink be evenly injected into the ink cartridge 2. When the slider 42 moves to the appropriate position, the single chip computer 3 controls the right angle motor 49, the output shaft of the right angle motor 49 drives the screw 41 to reverse, and the slider 42 moves backward with the rotating stirring frame 43, and the cycle is repeated, so that the ink in the ink cartridge is quickly stirred, and the ink attached to the inner wall of the ink cartridge is scraped off at all times, and the ink filling work can be performed evenly, and the ink can be prevented from adhering and condensing while the ink is evenly filled. At the same time, the single chip computer 3 controls the motor 482 to operate, and the motor 482 drives the ink roller 481 to rotate, and the ink roller After a series of rotations, 481 spreads the evenly spread ink on the ink-loving surface of the PS plate. The single-chip computer 3 controls the operation of the motor 2 485, which drives the plate cylinder 483 to rotate, and the rubber-coated cylinder 484 also rotates accordingly. When the rubber-coated cylinder 484 contacts the PS plate on the surface of the plate cylinder 483, the ink on the graphic part of the PS plate is adhered to the surface of the rubber-coated cylinder 484, and the rubber-coated cylinder 484 continues to rotate, and the rubber-coated cylinder 484 contacts the surface of the printing material, transfers the ink to the printing material, and completes the printing work.
