Description

Technical Field

[0001] The utility model relates to the technical field of inkjet printers, in particular to an automatic ink supply digital printer. Background Art

[0002] Inkjet printers can be divided into two types according to the working principle: solid inkjet and liquid inkjet. The liquid inkjet method can be further divided into bubble jet and liquid piezoelectric jet. The bubble technology sprays ink onto the printing medium by heating the nozzle to generate bubbles in the ink. After years of development, the technology of inkjet printers has made great progress. Ink liquid is an essential part of inkjet printers, and the printer continuously consumes ink liquid during the printing process.

[0003] After searching, the applicant found that a Chinese patent disclosed "an ink supply device for a printer", with the publication (announcement) number of "CN215751463U". This patent mainly sets up a rotatable ink supply device and a fixing device, so that the ink supply device can be applied to most printers by relying on the fixing device. The ink supply device is hung on the fixing device, and the fixing device can be hung on the outer side wall of most printers. The fixing property can be increased by clamping blocks, which greatly enhances the practicability of the ink supply device and reduces ink supply abnormalities caused by unnecessary factors such as dumping. However, this ink supply device requires manual addition of ink to the ink barrel. Once the ink in the ink barrel is exhausted without knowing it, it is easy to cause empty spraying. At this time, it is not only troublesome to resume ink supply, but also seriously damages the inkjet nozzle, seriously affecting the service life of the inkjet nozzle, and it is not convenient to disassemble and replace the ink storage box, so the practicability is not good. Therefore, we propose an automatic ink supply digital printer. Content of the Utility Model

[0035] In an embodiment of the present utility model: The booster pump 140 is fixed on the guiding track 121 and is fixedly connected to the right end of the guiding track 121. At the bottom of the ink storage box 125, an inkjet nozzle 142 is fixed. The number of the inkjet nozzles 142 is not limited;

[0036] In an embodiment of the present utility model: The number of the guiding grooves 158 is three. Because the number of the arranged guiding grooves 158 is three, it is convenient for the fixed block 157 to be stuck in three gears for positioning, and the use effect is good;

[0037] Working principle:

[0038] First, by starting the controller 5, the staff places the printing paper main body 7 to be printed at the position of the paper inlet 6, so that the printing paper main body 7 is placed at the center position of the paper inlet 6, thereby ensuring the printing effect. Then, the controller 5 controls the hydraulic cylinder 124 to drive the set ink storage box 125 and the inkjet nozzle 142 at the bottom to move. When moving to the position where inkjet printing is required, the controller 5 controls the hydraulic cylinder 124 to stop. At this time, with the telescopic movement of the set telescopic cylinder 152, the set fixed block 157 is driven to be stuck into the inside of the set guiding groove 158 to realize positioning. At the same time, the controller 5 controls the booster pump 140 and the connecting hose 138 to extract the ink in the ink storage tank 132. The inkjet nozzle 142 performs inkjet printing on the printing paper main body 7 at the paper inlet 6. After printing is completed, the printing paper main body 7 pops out from the paper outlet 4, realizing the inkjet printing of the whole process;

[0039] After being used for a period of time, the amount of ink inside the inkjet cartridge gradually decreases. At this time, the floating ball 128 will lower its height as the ink flow rate decreases. Since the liquid level sensor 127 is electrically connected to the controller 5, when the liquid level sensor 127 is set to issue an instruction when the ink amount is less than 30%, after receiving the instruction, the controller 5 starts the booster pump 140 and the connecting hose 138 to extract the liquid in the inkjet tank. When the inkjet tank needs to be disassembled, first pull the pull block 9 upwards to open the cover plate provided on the upper part of the printer main body 1, and extract the snap ring 136 from the inside of the card slot 135 and the fixing ring 134. At this time, the ink will not flow out from the bottom of the connecting hose 138, realizing the disassembly of the connecting hose 138. Then, pull out the ink storage cartridge 125 from the guide frame 131 to disassemble the ink storage cartridge 125. Thus, the entire working process ends.
