Description

Technical Field

[0001] The utility model relates to the technical field of printing, and more specifically to an inking mechanism for flexographic printing which is convenient for inking. Background Art

[0002] Flexographic printing refers to a printing method that uses a flexible plate to transfer ink through an anilox roller. The layout structure of the printing plate is the same as that of the relief printing plate, with the image and text part raised (that is, the image and text are higher than the non-image and text part), and both are direct printing. The flexographic printing machine is generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding (including folding). Its working principle is: first, the text and image to be printed are made into a printing plate, installed on the printing press, and then the ink is applied to the place where the text and image are on the printing plate by hand or by the printing machine, and then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass and ceramics), thereby replicating the same printed product as the printing plate.

[0003] For example, the authorization announcement number CN214727417U discloses a rubber roller brushing device for a printing machine. The ink is sprayed directly onto the rubber roller through the cooperation of the arc-shaped ink disk and the nozzle, and the ink on the rubber roller is evenly coated by the cooperation of the scraper rod and the scraper head. The excess ink can drip into the ink receiving box for subsequent use, thereby improving the utilization rate of the ink and minimizing the waste of ink. The rubber roller can be directly driven to rotate through the cooperation of the rotating shaft and the rotating plate, thereby improving the brushing efficiency. The rubber roller can be cleaned through the cooperation of the cleaning liquid pipe and the cleaning brush of the cleaning component to ensure the cleanliness of the rubber roller surface.

[0004] However, during use, the ink is sprayed directly and then the ink on the rubber roller is evenly applied, and it cannot be guaranteed that every part of the rubber roller is coated with the same amount of ink. Different amounts of ink will lead to poor printing results. When cleaning, the scraper rod and scraper head need to be cleaned, which increases the time cost. Utility Model Content

[0023] like Figure 1 to Figure 2 As shown,

[0024] The invention discloses an inking mechanism for flexographic printing which is convenient for inking, comprising an anilox roller, a frame 1 and a rubber roller 2 movably connected to the frame 1, wherein the outer wall of the anilox roller contacts the outer wall of the rubber roller 2, and the rubber roller 2 is used for inking the outer wall of the anilox roller. The frame 1 comprises a main body and a cover 11, and the cover 11 is sleeved on the lower end of the frame 1. The cover 11 is detachably connected to the frame 1, and the outer wall of the frame 1 is protected by the cover 11 to prevent the outer wall of the frame 1 from being stained with ink during the inking process.

[0025] An ink fountain is provided under the rubber roller 2, and ink is injected into the ink fountain. The rubber roller 2 extends into the ink fountain to take ink. Connecting rods 3 are provided at both ends of the rubber roller 2. The connecting rods 3 are rotatably connected to the bearing seat 4. The bearing seat 4 and the frame 1 are slidably connected. The bearing seat 4 moves in the frame 1 to drive the rubber roller 2 to rise and fall, thereby realizing the adjustment of the height of the rubber roller 2.

[0026] A moving assembly is provided between the bearing seat 4 and the frame 1, and the moving assembly includes a hydraulic cylinder 5, a guide rod 6 and a slider. The hydraulic cylinder 5 is electrically connected to a controller 12, and the controller 12 is placed on the outer wall of the frame 1. The output distance of the hydraulic cylinder 5 is controlled by the controller 12, so as to achieve the purpose of accurately adjusting the height of the rubber roller 2.

[0027] The output end of the hydraulic cylinder 5 is connected to the lower end surface of the bearing seat 4. A cavity 8 for the hydraulic cylinder 5 to be placed is opened on the frame 1. The slider is placed on the upper end surface of the bearing seat 4. A connecting hole is opened on the bearing seat 4. The bearing seat 4 is connected to the sliding seat 7 by a screw passing through the connecting hole.

[0028] The guide rod 6 is placed in the cavity 8. There are two guide rods 6, which are symmetrical. A positioning hole 9 connected to the cavity 8 is opened on the outer wall of the frame 1. There is a screw in the positioning hole 9. The screw assists the hydraulic cylinder 5 to limit the bearing seat 4.

[0029] The bearing seat 4 and the guide rod 6 are slidably connected, one end of the guide rod 6 is fixed to the frame 1, and the bearing seat 4 and the slide seat 7 are provided with mutually connected through grooves, and the guide rod 6 passes through the through grooves. Both ends of the guide rod 6 are fixedly connected to the inner wall of the cavity 8. A spring 10 is sleeved on the guide rod 6, one end of the spring 10 is connected to the inner wall of the cavity 8, and the other end of the spring 10 is connected to the upper end surface of the slider. The elastic force of the spring 10 further limits the slider and the bearing seat 4 to enhance its stability.

[0030] Working principle: when it is necessary to apply ink to the surface of the rubber roller 2, the hydraulic cylinder 5 is driven to output through the controller 12, driving the slider and the bearing seat 4 to slide on the guide rod 6, changing the height of the rubber roller 2, and then immersing the rubber roller 2 in the ink fountain so that the outer wall of the rubber roller 2 is completely in contact with the ink. After adjusting to a suitable height, the hydraulic cylinder 5 is stopped by the controller 12, and the screw is inserted into a suitable positioning hole 9 so that the screw assists the hydraulic cylinder 5 to position the rubber roller 2. After the ink is taken out, the screw is removed, and the hydraulic cylinder 5 is driven again to make the outer wall of the rubber roller 2 contact with the outer wall of the anilox roller to apply ink to the anilox roller. The height of the rubber roller 2 can be adjusted according to the ink content in the ink fountain so that the rubber roller 2 is completely immersed in the ink.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
