Problems solved by technology

Existing general technology, such as patent CN101117055A, is to control the liquid level of the ink cartridge through the detection of the liquid level sensor, and to control the ink environment pressure, pressure and liquid in the ink cartridge through the pressure generator (such as positive and negative pressure gas generating device, etc.) The level control is completely independent, and there are many sensors and control devices used, especially gas devices and liquid devices. Once some devices (such as liquid level sensors) fail, the ink will directly enter the gas device, which will cause serious damage to the system. irreparable damage

Embodiment Construction

[0016] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0017] The embodiment of the present invention provides an ink cartridge liquid level and pressure control device, such as figure 1 As shown, it includes: an ink pool 101, an ink cartridge 102, a nozzle 103, a pressure sensor 104, an ink inlet pump 105, an ink return pump 106, and a controller 107, wherein:

[0018] The ink pool 101 is connected to the atmosphere and includes an ink inlet port and an ink return port. The ink inlet port is located at the bottom of the ink pool 101 , and the ink return port is located at the top of the ink pool 101 .

[0019] The ink cartridge 102 is an airtight container, which communicates with the outside world through an ink inlet, an i...

Abstract

The invention relates to a united control device for ink box liquid level and pressure. The device includes: a nozzle connected to the ink cartridge; an external ink pool connected to the inlet of the ink cartridge through an ink inlet pump; an ink return pump connected to the external ink pool through a pipeline at one end and connected to the outlet of the ink cartridge at the other end; a pressure sensor for pressure The sensor is installed on the ink cartridge to detect the actual pressure value inside the ink cartridge; the controller, the controller collects the data of the pressure sensor, calculates the control voltage of the ink inlet pump and the ink return pump and outputs it to control the ink inlet pump and the ink return pump The actual output flow of the pump, thereby controlling the pressure and liquid level in the ink cartridge. The invention only needs one pressure sensor to realize dual control of liquid level and pressure, and the reliability of the whole device is greatly enhanced due to the reduction of liquid level sensors with poor reliability.

Description

technical field [0001] The invention relates to the technical field of printing ink supply, in particular to an ink cartridge liquid level and pressure combined control device and method. Background technique [0002] The commonly used ink-jet printing ink supply system in the prior art usually uses the ink cartridge as the print nozzle, that is, the ink cartridge directly provides ink and printing pressure at the same time. Existing general technology, such as patent CN101117055A, is to control the liquid level of the ink cartridge through the detection of the liquid level sensor, and to control the ink environment pressure, pressure and liquid in the ink cartridge through the pressure generator (such as positive and negative pressure gas generating device, etc.) The level control is completely independent, and there are many sensors and control devices used, especially gas devices and liquid devices. Once some devices (such as liquid level sensors) fail, the ink will direc...
