Description

Technical Field

[0001] The utility model belongs to the technical field of printing machines, in particular to a rotary double-sided printing machine. Background Art

[0002] A machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate mounting, 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 and mounted on the printing press. Then, the ink is applied to the places with text and images on the printing plate by humans or the printing press, 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. The invention and development of the printing press plays an important role in the dissemination of human civilization and culture. Therefore, in modern printing workshops, a rotary double-sided printing press is needed to facilitate high-speed printing of the printing device.

[0003] At present, a Chinese patent with announcement number CN218906619U discloses a rotary double-sided printing press, which relates to the technical field of printing press equipment, including a feed table, a fixed frame is fixedly connected to the upper surface of the feed table, a spring is fixedly connected to the center of the inner wall of the fixed frame, the other end of the spring is fixedly connected to a fixed plate, a fixed block 2 is fixedly connected to the lower surface of the fixed plate, a roller is arranged between the two fixed blocks 2, a fixed shaft 1 is fixedly connected on both sides of the roller, the two fixed shafts 1 respectively penetrate the surface of the rotatably connected fixed block 2, a fixed block 4 is fixedly connected to the side of the lower surface of the fixed plate away from the fixed block 2, a printing wheel 1 is arranged between the two fixed blocks 4, and a fixed block 1 is fixedly connected to one side of the feed table, which solves the problem that when the thickness of the printed products is different during the printing process, different printing equipment needs to be replaced to achieve a better printing effect, thereby reducing the printing work efficiency.

[0004] However, when the above device is printing on cardboard, due to the large amount of cardboard piled up, the surface of the cardboard may be contaminated with dust during transportation. At this time, if the cardboard is not cleaned and the material enters the printing device in a state of being contaminated with dust, the printing device may be stuck or the printed product may be unqualified, resulting in a waste of materials.

The inner wall cross-section of the fixing cylinder 6 and the fixing block 7 are both rectangular structures. The fixing block 7 can slide into the fixing cylinder 6 to fix the cleaning roller 4. After the fixing block 7 is separated from the inner wall of the fixing cylinder 6, the cleaning roller 4 can be disassembled and replaced to ensure the qualified quality of printed product production. Both ends of the cleaning roller 4 are provided with fixing grooves 8, and the inner wall of one end of the fixing groove 8 is fixedly connected to a fixing spring 9. The fixing spring 9 is fixedly connected to the fixing block 7. The fixing spring 9 can apply pressure to the fixing block 7 through the fixing spring 9, so that the fixing block 7 can slide into the inner wall of the fixing cylinder 6 through the inner wall of the fixing groove 8, so that the cleaning roller 4 can be fixed.

[0028] Reference Figure 2-3The connection mechanism includes two symmetrically distributed connection blocks 10, which are rotatably connected to the fixed cylinder 6 through a bearing. The two connecting plates 3 are each provided with a T-shaped connection groove 11 on one opposite side. The inner wall of the connection groove 11 at the same end contacts with the connection block 10 and forms a sliding fit.
