Ink injection amount detecting system and method for ink box

Abstract

The invention relates to an ink injection amount detecting system and method for an ink box. The ink injection amount detecting system comprises the ink box and an ink injection machine; the ink box comprises an ink box body which comprises an ink storage bin and an ink injection hole formed in the ink storage bin; the ink injection machine comprises a first pipeline, a second pipeline, a carrier,a pressure gauge, an ink supply part, an air control valve, a vacuum pump and a controller; an air outlet of the air control valve communicates with a ventilation channel of the ink supply part through the first pipeline, and the first pipeline does not make contact with ink in the ink supply part; the pressure gauge is arranged at the bottom of the carrier, and the ink storage bin communicates with an ink discharging channel of the ink supply part through the second pipeline inserted into the ink injection hole; a switch valve is arranged on the position, close to the ink injection hole, ofthe second pipeline, and a flowmeter is arranged on the position, close to the ink injection hole, in the second pipeline; and the controller is connected with the air control valve, the switch valve,the vacuum pump, the pressure gauge and the flowmeter. The ink injection amount is monitored in real time, and the amount of the ink injected into the ink box can be quickly and conveniently known without manually visually observing the scale of an ink measuring device.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a system and method for detecting the ink filling amount of an ink cartridge. Background technique [0002] An inkjet printer is a device that ejects ink through the nozzles of the print head onto recording media such as paper to form character or graphic records under the drive of a printing signal. With the continuous development of inkjet technology, the volume of inkjet printers is getting smaller and smaller. Correspondingly, the volume of ink cartridges used as ink storage containers is also getting smaller and smaller. The consumption of ink cartridges is fast, and users need to constantly replace ink cartridges. [0003] Since the ink cartridges include plastic, film and other components, when replacing the ink cartridges, if the ink cartridges are discarded directly, it will cause waste of resources and environmental pollution, and will also increase the cost of using t...

Problems solved by technology

[0003] Since the ink cartridges include plastic, film and other components, when replacing the ink cartridges, if the ink cartridges are discarded directly, it will cause waste of resources and environmental pollution, and will also increase the cost of using the ink cartridges. Therefore, it is necessary to recycle the ink cartridges to improve the utilization of the ink cartridges , reduce the cost of ink cartridges, avoid waste of resources and environmental pollution
