Abstract
Description
Technical Field
[0001] The present application relates to the technical field of printing presses, and in particular to a printing roller for a printing press. Background Art
[0002] A printing press is a machine used to print text and images. Modern printing presses generally consist of mechanisms such as plate mounting, inking, embossing, and paper feeding (including folding). Its working principle is as follows: the text and image to be printed are first made into a printing plate and mounted on the printing press. Ink is then applied to the areas of the plate where the text and image appear, either manually or by the printing press. The ink is then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood, glass, and ceramics), thereby reproducing a printed product identical to the printing plate. During use, ink is applied to the outer surface of the printing roller and then transferred to the printed product.
[0003] In the prior art, when cleaning the printing roller, the brush is brought into contact with or out of contact with the roller by engaging a limiting rod with different limiting grooves provided on a sleeve. When the brush is not needed to clean the roller, the limiting rod is engaged with the limiting groove provided on the upper end of the sleeve. When the brush is needed to clean the roller, the limiting rod is engaged with the limiting groove provided on the lower end of the sleeve. However, during the brush cleaning process, when the brush contacts the printing roller, the ink on the printing roller easily adheres to the brush. As the brush moves, the ink adheres to the printing roller again, resulting in inadequate cleaning of the printing roller and reduced cleaning effect of the printing roller. Therefore, those skilled in the art provide a printing roller for a printing press to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0026] The following is combined with Figure 1-4 This application is described in further detail.
[0027] The embodiment of the present application discloses a printing roller for a printing machine. Figure 1-4A printing roller for a printing press comprises a bracket 1 and a printing roller 2 rotatably arranged on the bracket 1. A U-shaped frame 3 is fixed to one side of the bracket 1. An L-shaped frame 4 is slidably provided at the bottom end of the U-shaped frame 3. A driving assembly 5 for driving the L-shaped frame 4 to move is provided at the top of the U-shaped frame 3. A storage box 6 is fixed to the horizontal end of the L-shaped frame 4. A mounting bracket 7 is fixed to the top of the storage box 6. A cleaning brush 8 that contacts the printing roller 2 is provided at the top of the mounting bracket 7. The cleaning brush 8 is connected to the mounting bracket 7 through a mounting assembly 9. A water pipe 10 is fixed to the top of the storage box 6. The water pipe 10 is connected to a nozzle 11 facing the cleaning brush 8.
[0028] In this embodiment, when the printing roller 2 needs to be cleaned, the water pipe 10 is first connected to the external water source, and water is supplied to the water pipe 10 through the external water source. Then, under the movement of the driving component 5, the L-shaped frame 4 is driven to move, and the L-shaped frame 4 drives the storage tank 6 to move. The storage tank 6 drives the cleaning brush 8 on the mounting frame 7 to move along the printing roller 2, so that the cleaning brush 8 cleans the surface of the printing roller 2. At the same time, with the cooperation of the water pipe 10 and the nozzle 11, the contact position between the cleaning brush 8 and the printing roller 2 is flushed, and then the flushing water falls and is collected in the storage tank 6, thereby reducing the ink residue on the surface of the cleaning brush 8, facilitating the full cleaning of the printing roller 2, and improving the cleaning effect of the printing roller 2.
[0029] In a further embodiment, Figure 1-3 As shown, the driving assembly 5 includes a first slider 51 fixedly arranged at the vertical end of the L-shaped frame 4, a first slide groove 52 for the first slider 51 to slide is opened at the top of the U-shaped frame 3, a screw rod 53 threadedly connected to the first slider 51 is rotatably connected in the first slide groove 52, and a driving motor 54 fixed to the screw rod 53 is fixed on one side of the U-shaped frame 3. The mounting assembly 9 includes a first magnet 91 fixedly arranged at the top of the mounting frame 7, and a second magnet 92 magnetically connected to the first magnet 91 is fixed to the bottom end of the cleaning brush 8.
[0030] When cleaning the printing roller 2, the movement of the driving motor 54 drives the rotation of the screw rod 53, the screw rod 53 drives the movement of the first slider 51, the first slider 51 drives the movement of the L-shaped frame 4, the L-shaped frame 4 drives the movement of the storage tank 6, and the storage tank 6 drives the cleaning brush 8 on the mounting frame 7 to move, so that the cleaning brush 8 moves to clean the surface of the printing roller 2. At the same time, with the cooperation of the water pipe 10 and the nozzle 11, the contact position between the cleaning brush 8 and the printing roller 2 is flushed, thereby reducing the adhesion residue of ink, facilitating the full cleaning of the printing roller 2, and improving the cleaning effect of the printing roller 2. When the cleaning of the printing roller 2 is completed, the driving motor 54 moves again, and the storage tank 6 is moved to the end position of the printing roller 2 to avoid affecting the use of the printing roller 2. When the cleaning brush 8 needs to be disassembled and replaced, the first magnet 91 and the second magnet 92 are connected to facilitate the replacement and use of the cleaning brush 8.
[0031] In a further preferred embodiment of the present invention, Figure 4 As shown, the bottom end of the bracket 1 is connected with an adjustment plate 12, and the bottom end of the adjustment plate 12 is fixed with a base 13. The bottom end of the bracket 1 is provided with a through slot 14 for the adjustment plate 12 to pass through. The through slot 14 is connected to the adjustment plate 12 through a sliding component 15. An adjustment component 16 is provided in the through slot 14 to drive the adjustment plate 12 to move.
[0032] When printing on printed materials of different thicknesses, the movement of the adjusting component 16 drives the bracket 1 to move up and down, and the bracket 1 drives the printing roller 2 to move up and down, so that the printing roller 2 adapts to the printed materials, thereby facilitating the printing of the printed materials and improving the printing efficiency of the printed materials.
[0033] In a further embodiment, Figure 4 As shown, the sliding assembly 15 includes a second slider 151 fixedly arranged on both sides of the adjustment plate 12, and a second sliding groove 152 for the second slider 151 to slide is provided on both sides of the inner wall of the through groove 14. The adjustment assembly 16 includes a groove 161 opened on the inner wall of the through groove 14, and a moving block 162 is slidably connected in the groove 161.
