Problems solved by technology
This kind of movement will make the cover 122 always cover the cover 122 completely after contacting the inkjet head C1 with one side edge first, which will make the side edge prone to wear and affect its achievable airtightness.
Especially in today's printing systems, an air suction pump (not shown) is often added to connect with the cover 122 to extract the remaining ink remaining in the inkjet head C1. If, as mentioned above, poor airtightness occurs time, the suction pump will lose its function, and the residual ink cannot be smoothly pumped out
[0016] In addition, this linkage method of pushing the slider 121 through the ink cartridge C to complete the purpose of covering needs to leave a certain space in advance for the ink cartridge C to move laterally (the distance D in the figure), so that the maintenance area needs to be occupied. The larger horizontal space increases the width of the printing system, which is a shortcoming that urgently needs to be improved for today's increasingly compact and lightweight business machines.

Embodiment Construction
[0033] see image 3 , which is a schematic diagram of the inkjet maintenance device of the present invention installed in a printing system. What has been explained here is that in current color printing systems, generally speaking, two ink cartridges (such as a black ink cartridge and a three-color ink cartridge, or two three-color ink cartridges) are installed, so in this comparison In the preferred embodiment, it is designed to be suitable for two ink cartridges. Certainly, under different implementation modes (such as being used in a monochrome printing system), those who have the technology can of course also implement according to the content disclosed below in this manual, and change it into a design suitable for a single ink cartridge, Therefore, details are not described here, and a printing system with two ink cartridges C is taken as an example for illustration.
[0034] As shown in the figure, the two ink cartridges C are arranged side by side, and move back and ...

A protecting unit for the ink-jet head of an ink box is composed of a casing base with the first moving path parallel to the bottom surface of casing base and the second moving path perpendicular to said bottom surface, a slide block sliding back and forth in said first moving path and with at least one pair of guide slots, a cover holder sliding back and forth in said second moving path and with two side flanges embedded in said guide slots, and a cover on said cover holder.
Description
technical field [0001] The invention relates to an inkjet maintenance device, in particular to an inkjet maintenance device whose cover is vertically lifted up and down to seal the cover. Background technique [0002] Inkjet printing system has been widely used in various business machines. Its main working principle is to drive the ink cartridge to move by its internal stepping motor, and at the same time eject ink from the inkjet head of the ink cartridge to the paper. And complete the printing job. [0003] However, during the printing process, there are often excess ink droplets remaining near the inkjet head, or dust particles from the environment. If they are not removed in time, the inkjet head will often be blocked and the ink will not flow smoothly. , affecting print quality. Therefore, in the printing system, it is generally divided into a printing work area and a maintenance area. The maintenance area is located on the side of the printing system, and an inkjet ...
