Technical Field

[0001] The utility model relates to the technical field of monochrome double-sided offset printing machines, in particular to a high-efficiency monochrome double-sided offset printing machine. Background Art

[0002] A monochrome double-sided offset printing machine is a printing device specially used for printing monochrome images and capable of double-sided printing. It usually adopts offset printing technology and can print monochrome images on both sides of the paper, thereby improving printing efficiency and saving paper costs. It has the advantages of fast printing speed, high printing quality, and easy operation. It is a common printing device in the printing industry.

[0003] The existing related technologies often have the following defects: when a single-color double-sided printing machine is in use, the offset-printed paper will fall onto the surface of the receiving paper board. As the amount of offset-printed paper on the receiving paper board gradually increases, the worker needs to manually turn the handle to adjust the height of the receiving paper board. Manually adjusting the height of the receiving paper board increases the labor intensity of the workers, which may cause hand fatigue and inconvenience, especially when used for a long time.

[0004] Therefore, the utility model provides a high-efficiency single-color double-sided offset printing machine. Utility Model Content

[0016] Preferably, an extension plate is fixedly connected to one side of the cleaning plate, and a scraper plate is fixedly connected to a side of the extension plate away from the cleaning plate.

[0017] The effect achieved by the above components is: when the cleaning plate moves, it will drive the extension plate to move, the movement of the extension plate will drive the scraper to move, the movement of the scraper will slide along the surface of the ventilation holes on the surface of the paper output bin, thereby scraping off the more stubborn dust, making it easier for the cleaning plate to wipe and improving the dust cleaning effect.

[0018] Preferably, one end of the driving rod away from the cleaning plate is fixedly connected to a connecting plate, and one side of the connecting plate is fixedly connected to a U-shaped plate.

[0020] In summary:

[0021] 1. In the utility model, by setting a feeding structure, the two ends of a spring with appropriate elasticity are hung on the first hook and the second hook respectively according to the weight of the paper, and the paper after offset printing will fall onto the surface of the receiving paper board. When the accumulated paper on the receiving paper board reaches a certain weight, the receiving paper board will drive the slider to slide in the slide groove with the help of the pressure exerted by the paper. When the slider moves, it will drive the first hook to move. The movement of the first hook will stretch the spring. When the accumulated paper on the receiving paper board reaches the moving amount, it is convenient to remove the paper from the receiving paper board, avoiding the need to manually adjust the position of the receiving paper board when offset printing the paper.

[0022] 2. In the utility model, by setting a cleaning structure, the driving rod is pulled, and the driving rod moves to slide in the fixed plate. The movement of the driving rod drives the cleaning plate to slide along the surface of the paper output bin. The movement of the cleaning plate will wipe the position where the ventilation holes on the surface of the paper output bin are opened, thereby erasing the dust blocked in the ventilation holes, thereby improving the effect of the heat dissipation fan on air-drying the surface of the paper after offset printing.

[0030] The specific arrangement and function of the material discharging structure 7 and the cleaning structure 8 will be described in detail below.

[0031] Reference Figure 2 and Figure 3 and Figure 4As shown, in this embodiment: the unloading structure 7 includes two rectangular plates 701, the two rectangular plates 701 are fixedly connected to the surface of the base 1, a slide groove 702 is opened on the surface of the rectangular plate 701, the inner wall of the slide groove 702 is slidably connected with a slider 703, the surface of the slider 703 is fixedly connected with a first hook 704, the inner wall of the slide groove 702 is fixedly connected with a second hook 705, the surface of the first hook 704 is sleeved with a spring 706, the other end of the spring 706 is sleeved on the surface of the second hook 705, and the side of the two sliders 703 close to each other is fixedly connected with a connecting paper board 707. The surface of the slider 703 is fixedly connected to the limit plate 708, and the surface of the rectangular plate 701 is slidably penetrated by a latch 709. The latch 709 will slide in the rectangular plate 701 and gradually insert into the limit plate 708. When the latch 709 is inserted into the limit plate 708, the latch 709 reaches the position of limiting the limit plate 708, thereby limiting the position of the receiving paper board 707, thereby preventing the spring 706 from driving the receiving paper board 707 to move due to the change in pressure on the receiving paper board 707 when removing the paper, thereby facilitating the removal of the paper from the receiving paper board 707. One end of the latch 709 is fixedly connected to a rope 710, and the end of the rope 710 away from the latch 709 is fixedly connected to the rectangular plate 701. When the latch 709 moves, it will drive the rope 710 to move, and the rope 710 reaches the position of limiting the latch 709, thereby preventing the latch 709 from being lost after being pulled out of the limit plate 708. The surface of the receiving paper board 707 is fixedly connected with an anti-skid pad 711, which is made of rubber. The paper after offset printing will fall onto the anti-skid pad 711 on the surface of the receiving paper board 707. The anti-skid pad 711 can increase the friction between the paper and the receiving paper board 707, thereby preventing the paper from falling onto the surface of the receiving paper board 707 and slipping.

[0032] Reference Figure 5As shown, specifically, the cleaning structure 8 includes two fixed plates 81, both of which are fixedly connected to the surface of the paper discharge bin 5, a driving rod 82 is slidably penetrated through the surface of the fixed plate 81, one end of the driving rod 82 is fixedly connected to a cleaning plate 83, and a bolt 84 is threadedly connected to the surface of the fixed plate 81. An extension plate 85 is fixedly connected to one side of the cleaning plate 83, and a scraper 86 is fixedly connected to the side of the extension plate 85 away from the cleaning plate 83. When the cleaning plate 83 moves, it will drive the extension plate 85 to move, and the movement of the extension plate 85 will drive the scraper 86 to move. The movement of the scraper 86 will slide along the surface of the ventilation hole 9 on the surface of the paper discharge bin 5, thereby scraping off the stubborn dust, which is convenient for the cleaning plate 83 to wipe and improve the dust cleaning effect. One end of the driving rod 82 away from the cleaning plate 83 is fixedly connected to a connecting plate 87, and one side of the connecting plate 87 is fixedly connected to a U-shaped plate 88. The movement of the U-shaped plate 88 will drive the connecting plate 87 to move, and the movement of the connecting plate 87 will simultaneously drive the two driving rods 82 to move. The U-shaped plate 88 reaches a position that is convenient for pulling the connecting plate 87, thereby facilitating the simultaneous pulling of the two driving rods 82.

The anti-skid pad 711 can increase the friction between the paper and the receiving paper board 707, thereby preventing the paper from falling onto the surface of the receiving paper board 707 and slipping. When the accumulated paper on the receiving paper board 707 reaches a certain weight, the receiving paper board 707 will use the pressure exerted by the paper to drive the slider 703 to slide in the slide groove 702. When the slider 703 moves, it will drive the first hook 704 to move. The movement of the first hook 704 will stretch the spring 706. When the receiving paper board 707 moves to a suitable position, it pushes the latch 709, and the latch 709 will The locking cam 708 is in the state of being moved by the spring 706, so that the locking cam 708 can be easily removed from the locking cam 708.

[0034] When it is necessary to improve the offset printing effect of the monochrome double-sided offset printing machine, first turn the bolt 84, the bolt 84 will move in the fixed plate 81 with the help of the thread, and the bolt 84 will be out of contact with the driving rod 82 after moving to a suitable position, and then pull the U-shaped plate 88, the movement of the U-shaped plate 88 will drive the connecting plate 87 to move, and the movement of the connecting plate 87 will simultaneously drive the two driving rods 82 to move, the movement of the driving rod 82 will slide in the fixed plate 81, and the movement of the driving rod 82 will drive the cleaning plate 83 to slide along the surface of the paper discharge bin 5, and the movement of the cleaning plate 83 will wipe the position where the ventilation hole 9 on the surface of the paper discharge bin 5 is opened, thereby erasing the dust blocked at the ventilation hole 9, and the cleaning plate 83 will move. When moving, the extension plate 85 will be driven to move, and the movement of the extension plate 85 will drive the scraper 86 to move. The movement of the scraper 86 will slide along the surface of the ventilation hole 9 on the surface of the paper outlet bin 5, thereby scraping off the more stubborn dust, making it easier for the cleaning plate 83 to wipe and improve the dust cleaning effect. After cleaning the position where the ventilation hole 9 on the surface of the paper outlet bin 5 is opened, the U-shaped plate 88 is pushed in the opposite direction until the cleaning plate 83 is reset, and then the bolt 84 is turned. The bolt 84 will move in the fixing plate 81 with the help of the thread until the bolt 84 is tightly fitted on the surface of the driving rod 82, thereby limiting the driving rod 82 and then limiting the position of the cleaning plate 83.
