Description

Technical Field

[0001] The present invention relates to the technical field of printing presses, and more particularly to an ink storage device for a printing press with a total amount monitoring function. Background Art

[0002] With the development of inkjet printing technology, currently available inkjet printers use ink cartridges to supply ink. The ink is transported to a printhead via an ink tube. Driven by a printing signal, the printhead ejects the ink onto a printing medium such as paper to print characters or graphics. However, after a period of use, the ink cartridges of existing inkjet printers deplete and must be replaced. This replacement method typically involves discarding the depleted cartridge and replacing it with a freshly stocked cartridge. This inevitably results in wasted ink.

[0003] Patent application number 201210171130.2 discloses an ink storage device for an inkjet printer, comprising an ink cartridge and an ink barrel for refilling the cartridge. The cartridge comprises a housing; a guide plate mounted within the housing, the guide plate comprising an inclined ink guide plate disposed at the outlet of an ink inlet pipe and an ink return pipe, and an upper top plate connected to the upper end of the ink guide plate, with a bubble channel formed between the upper top plate and the upper top surface of the housing; an ink baffle disposed below the guide plate, the ink baffle having a gap for ink flow between the ink baffle and the side wall of the housing, an ink-containing gap between the ink baffle and the inner bottom surface of the housing, and the lower end of the ink outlet pipe extending through the ink baffle into the ink-containing gap; and a bubble guide device disposed within the bubble channel for guiding and eliminating bubbles. This patent eliminates the need to replace ink cartridges, saving printing costs. Furthermore, it effectively eliminates bubbles in the ink cartridge, improving print quality.

[0004] However, the above patents and the prior art both monitor the total amount of stored liquid by installing a liquid level sensor inside the ink cartridge. However, the liquid level sensor has reduced sensitivity due to being in the ink cartridge for a long time, and is not easy to observe and calibrate in real time. Conventional liquid level sensors only display and remind the highest and lowest ink levels, and are unable to monitor in real time and understand the ink level. This poses a major problem in monitoring the ink level of the ink storage device.

[0005] Therefore, how to provide an ink storage device for a printing press with a total amount monitoring function is a problem that those skilled in the art urgently need to solve. Summary of the Invention

[0006] In view of this, the present invention provides an ink storage device for a printing press with a total amount monitoring function, aiming to solve the above technical problems.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] An ink storage device for a printing press with a total amount monitoring function, comprising:

[0009] Box body;

[0010] The cover body is buckled on the top edge opening of the box body, and is provided with an ink filling interface, an ink outlet interface and a float limit port on the cover body. The ink filling interface is connected to an ink filling tube inserted into the inside of the box body, and the ink outlet interface is connected to an ink outlet tube inserted into the bottom of the box body.

[0011] The limiting tube is connected between the bottom wall of the box body and the bottom surface of the cover body, and corresponds to the floating scale limit opening, and the bottom of the limiting tube is provided with flow holes around it;

[0012] Floating ruler; the floating ruler is arranged in the limiting tube, and the top end passes through the floating ruler limiting opening;

[0014] Through the above technical solution, the ink storage device for a printing press provided by the present invention abandons the traditional principle of using a liquid level sensor for detection, and uses a float to monitor the liquid level, and reads the liquid level data through a numerical reading mechanism. On the one hand, it can monitor the liquid level in real time, and on the other hand, it is easy to maintain through an external numerical reading mechanism. Moreover, when the float is stuck, it is only necessary to manually extract the top of the float, which is convenient for timely calibration of the float. Not only is the structure simple, but the monitoring effect is also better.

[0015] Preferably, in the above-mentioned ink storage device for a printing press with a total amount monitoring function, a pump body and a filter are sequentially connected to the outside of the ink filling interface.
