Embodiment Construction

[0024] The features of the present invention and other relevant features are described in further detail below through the embodiments, so as to facilitate the understanding of those skilled in the art:

[0025] Such as Figure 1-Figure 6 As shown, an ink supply system includes a control module 1, a primary ink bottle 2, a metal secondary ink cartridge 3, and a metal tertiary ink cartridge 4, and the metal secondary ink cartridge 3 is provided with a secondary ink cartridge side wall to feed ink Holes 31, secondary ink cartridge top wall ventilation hole 32, secondary ink cartridge top wall liquid level sensor mounting hole 33, secondary ink cartridge bottom wall ink outlet hole 34, and secondary ink cartridge temperature sensor mounting hole 35, the metal tertiary ink cartridge 4. There is an ink inlet 41 on the top wall of the third-stage ink cartridge, an air hole 42 on the top wall of the third-stage ink cartridge, and an ink outlet hole 43 on the bottom wall of the third-...

Abstract

The invention discloses an ink supply system. The space between ink inlet holes in the side walls of both a first-level ink bottle and a second-level ink box is in pipeline connection with an electricpump, and thus ink in the first-level ink bottle is conveniently pumped to the metal second-level ink box; a positive and negative pressure generator is connected to the metal second-level ink box for adjusting the pressure in the metal second-level ink box, so that the metal second-level ink box well supplements the ink to a metal third-level ink box in the inkjet using process, the pressure between the metal third-level ink box and a micro-piezo inkjet printing head is stabilized advantageously, and stability of the inkjet quality is kept advantageously; and a solenoid valve is connected between an ink outlet hole in the bottom wall of the second-level ink box and an ink inlet in the top wall of the third-level ink box, and thus the situation that in the case of power outage, the ink lose the negative pressure, and consequently, the micro-piezo inkjet printing head drips the ink can be avoided.

Description

technical field [0001] The invention relates to an ink supply system. Background technique [0002] At present, the ink bottle of the existing ink supply system is connected to the ink cartridge through the ink pump, and then the ink cartridge sprays ink through the inkjet head. This secondary structure has the situation that the pressure in the ink cartridge will be unstable when the ink pump is working, resulting in Occurrence of unstable inkjet quality of inkjet head. [0003] In addition, the ink cartridge in the existing ink supply system only has a heating control function, but does not have a cooling control function, which is inconvenient to control the temperature of the ink cartridge within an appropriate range. [0004] Therefore, how to overcome the above existing defects has become an important issue to be solved urgently by those skilled in the art. Contents of the invention [0005] The present invention overcomes the disadvantages of the above technologie...
