Description

Technical Field

[0001] The invention relates to the technical field of printers, and in particular to an ink scraper maintenance device and a printer with the ink scraper maintenance device. Background Art

[0002] Inkjet printers turn colored liquid ink into tiny particles through nozzles and spray them onto printing paper. Some inkjet printers have three or four print heads to print yellow, magenta, cyan and black; some share one print head and print in four colors. The print head of the printer sprays ink droplets on the print medium to form images and texts. After printing for a period of time, the ink jet port of the print head is prone to residual ink, dust and impurities scraped from the printing paper, which can easily cause the ink jet port of the print head to be blocked, and the ink is cut off, which affects the quality of the printed image. At this time, the print head needs to be sucked and scraped to dredge the ink jet port. During the process of sucking and scraping the print head, the ink splashed from the ink jet port needs to be collected by a container and discharged in time. Once the dripping waste ink cannot be effectively discharged, it will not only affect the appearance but also easily cause pollution. When the print head is not working, the print head needs to be capped, otherwise the ink remaining on the surface of the print head is easy to dry and cause the ink jet port of the print head to be blocked. Therefore, in the structural design of the inkjet printer, an ink sealing maintenance device and an ink scraping maintenance device are generally provided. Most of the existing ink scraping maintenance devices are arranged with an ink scraping strip and an ink sealing strip on the service station. When the service station moves to the print head, the ink scraping strip cleans the ink jet port, and then the ink sealing strip seals the ink jet port. However, the existing ink scraper strips are prone to ink accumulation after repeated use, and ink mixing is prone to occur when cleaning the ink jet ports of the print head, resulting in poor cleaning effects. In addition, the ink sealing strips on the service station have poor sealing effects on the ink jet ports. Summary of the invention

[0029] Reference Figure 1 As shown, the ink scraping maintenance device according to an embodiment of the present invention is applied to a printer, and the ink scraping maintenance device is driven by a second power mechanism to move along a left-right straight line close to or away from the print head. The ink scraping maintenance device includes a mounting seat 100, a sponge roller 200 and an ink sealing rubber ring 300. The mounting seat 100 is arranged on the right side of the print head, and the mounting seat 100 can be close to or away from the print head; the sponge roller 200 is rotatably arranged at the left end of the mounting seat 100, and the sponge roller 200 is driven to rotate by the first power mechanism; the ink sealing rubber ring 300 is arranged on the mounting seat 100, and the ink sealing rubber ring 300 is arranged on the right side of the sponge roller 200. Compared with the prior art, the embodiment of the present invention is provided with a sponge roller 200 driven to rotate by a first power mechanism on the mounting seat 100. When not in operation, the mounting seat 100 moves toward the position of the print head, and the first power mechanism drives the sponge roller 200 to rotate. When the sponge roller 200 moves to the inkjet port of the printer nozzle, the rotating sponge roller 200 absorbs the ink on the inkjet port at different positions of itself, and the inkjet port is cleaned. Then the ink-sealing rubber ring 300 blocks the inkjet port. Since the ink-sealing rubber ring 300 has a certain elasticity, the blocking effect is good, and the effect of preventing ink from condensing and overflowing is good. In the non-operating state, the embodiment of the present invention absorbs the ink on the inkjet port of the print head at different positions of itself through the rotating sponge roller 200.
