Description

Technical Field

[0001] This utility model relates to the field of printing technology, and in particular to a printing press that facilitates ink cartridge replacement. Background Technology

[0002] A printing press generally consists of mechanisms for mounting the printing plate, inking, printing, and paper feeding. During operation, the text and images to be printed are first made into a printing plate, which is then mounted on the printing press. Ink is then applied manually or by the printing press to the areas on the printing plate containing the text and images, and the ink is directly or indirectly transferred to paper or other printing substrates, thus producing a printed product identical to the printing plate.

[0003] Existing printing press ink cartridges are usually designed to be installed upside down on the ink supply equipment. However, if the operator is not careful or skilled enough during the placement process, the ink cartridge may not be properly positioned, which may lead to problems such as ink leakage, air entering the system, or poor ink supply, affecting printing quality and normal equipment operation.

[0004] To address the existing problems, a printing press that facilitates cartridge replacement needs to be designed. Utility Model Content

The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0024] Example: A printing press that facilitates cartridge replacement, such as Figures 1-8As shown, the system includes a printing press 1, a switch door 101, a connecting plate 3, a sliding plate 4, an ink cartridge 6, a mounting ring 7, a hose 8, a connecting pipe 801, a first guide rod 9, a lifting plate 10, a docking ring 11, a telescopic rod 12, a first spring 13, a mounting plate 14, a sliding rod 15, a wedge block 16, a second spring 17, a lead screw 18, a second guide rod 19, an adjusting plate 20, and a sealing ring 21. The switch door 101 is rotatably connected to the left side of the printing press 1. A placement groove 2 is provided on the left side of the printing press 1, and a connecting plate 3 is connected within the placement groove 2. A sliding plate 4 is slidably connected to the connecting plate 3. A sliding groove is provided on the left side of the sliding plate 4 to facilitate pulling the sliding plate 4. Multiple docking slots 5 are evenly spaced on the sliding plate 4, each containing an ink cartridge 6. An mounting ring 7 is installed on the connecting plate 3, and multiple flexible tubes 8 are connected to the mounting ring 7. Each flexible tube 8 has a connecting tube 801 at its other end, which is used to insert into the ink cartridge 6 to extract the ink. A first guide rod 9 is connected to the placement slot 2, and a lifting plate 10 is slidably connected to the first guide rod 9. Multiple docking rings 11 are evenly spaced at the bottom of the lifting plate 10, and the docking rings 11 can fit against the bottle opening of the ink cartridge 6. The connecting pipe 801 is slidably connected to the docking ring 11, which is in contact with the ink cartridge 6. A telescopic rod 12 is installed at the top of the placement groove 2 to guide the first spring 13. The first spring 13 is connected between the top of the placement groove 2 and the lifting plate 10, and can apply pressure to the lifting plate 10. An installation plate 14 is connected inside the placement groove 2, and a sliding rod 15 is slidably connected to the installation plate 14. A wedge block 16 is connected to the front end of the sliding rod 15, which can limit the lifting plate 10. A second spring 17 is connected between the wedge block 16 and the installation plate 14. A lead screw 18 is rotatably connected to the lifting plate 10, and a rotating ball is connected to the top of the lead screw 18 to facilitate rotation of the lead screw 18. A second guide rod 19 is connected to the lifting plate 10, and an adjusting plate 20 is threadedly connected to the lead screw 18. The adjusting plate 20 is slidably connected to the second guide rod 19. Multiple connecting pipes 801 are connected to the adjusting plate 20. The adjusting plate 20 can drive the five connecting pipes 801 to adjust the length of the inserted ink cartridge 6. Sealing rings 21 are evenly spaced on the top of the lifting plate 10. The sealing rings 21 contact and cooperate with the connecting pipes 801 to seal the gap between the connecting pipes 801 and the mating ring 11.

[0025] When the ink cartridge 6 of the printing press 1 needs to be replaced, the operator first rotates the switch door 101 to open it, then pushes the push plate upward along the first guide rod 9. The lifting plate 10 moves all the components on it. When the lifting plate 10 moves, the telescopic rod 12 retracts, and the first spring 13 is compressed. When the lifting plate 10 moves to a certain position, it will squeeze the wedge block 16, causing it to move the sliding rod 15 backward. The second spring 17 is compressed. When the lifting plate 10 moves upward, it will no longer squeeze the wedge block 16, and the second spring 17 will return to its original position, aligning the sliding rod 15 with the wedge block 16. After resetting, the operator can release the lifting plate 10, which will be blocked by the wedge block 16 and remain stationary. The operator then pulls the sliding plate 4 along the connecting plate 3 using the actuating groove on the sliding plate 4. Once the sliding plate 4 has moved to a certain position, it will no longer be pulled. The operator can then remove the used ink cartridge 6 and place a new ink cartridge 6 in the corresponding docking slot 5, opening the cover of the ink cartridge 6. After the ink cartridge 6 is placed, the sliding plate 4 is pushed back to reset. Once the sliding plate 4 has reset, the length of the connecting rod can be adjusted. When the ink cartridge 6 is at the correct depth, the operator can rotate the lead screw 18. Rotation of the lead screw 18 will cause the adjusting plate 20 to move along the second guide rod 19. The adjusting plate 20 will then cause multiple connecting rods to rise and fall. When the connecting rods reach the appropriate depth position of the ink cartridge 6, the lead screw 18 will no longer be rotated. Then, the operator will hold the lifting plate 10 with one hand and push the wedge block 16 backward with the other hand to release its restraint on the lifting plate 10. The lifting plate 10 will then be moved downward along the first guide rod 9. When the lifting plate 10 is lower than the height of the wedge block 16, the operator can release the hand pushing the wedge block 16. The spring will then move the wedge block 16 downward. 6. Reset: During the movement of the lifting plate 10, the connecting tube 801 will be inserted into the bottle opening of the ink cartridge 6. When the lifting plate 10 moves to its original position, the docking ring 11 at the bottom of the moving plate will engage with the bottle opening of the ink cartridge 6 to seal it. At the same time, the connecting tube 801 will be fully inserted into the ink cartridge 6. When the lifting plate 10 resets, the telescopic rod 12 will also retract, and the first spring 13 will reset. The first spring 13 will continuously apply pressure to the lifting plate 10 to prevent the lifting plate 10 from moving. Then, the operator can close the switch door 101 to complete the replacement of the ink cartridge 6.
