Embodiment 1
[0023] Such as Figure 1~2 Shown is a preferred embodiment provided by the present invention.
[0024] The ink circulation method of the ceramic inkjet printing machine provided in this embodiment can keep the ink of the ceramic inkjet printing machine in the process of circulating and flowing continuously, so as to ensure that the solute will not be precipitated in the solvent, as follows:
[0025] Provide a control center 100, which can control the circulation of the entire ink path;
[0026] A first ink cartridge 101 and a second ink cartridge 102 for storing ink, an inkjet head 103 for inkjet, and an ink supply cartridge 104 for providing ink are provided;
[0027] Utilize the control center 100 to control the ink to circulate among the first ink cartridge 101, the ink channel 1031 of the inkjet head 103, the second ink cartridge 102 and the first ink cartridge 101 in sequence;
[0028] The control center 100 controls the ink to circulate among the second ink box 102 , t...
Embodiment 2
[0071] Such as image 3 Shown is another preferred embodiment provided by the present invention.
[0072] The difference between this embodiment and Embodiment 1 is that: image 3 As shown, in this embodiment, the first negative pressure device 112 and the second negative pressure device 113 apply different pressures to the first ink cartridge 101 and the second ink cartridge 102 respectively, that is, P 1 ≠P 2 , that is, the pressure acting on the ink in the first ink cartridge 101 and the ink in the second ink cartridge 102 is different, and the first ink cartridge 101 and the second ink cartridge 102 are arranged in parallel, and the upper liquid level of the ink inside it Being on the same level in theory, the height of the ink in the first ink cartridge 101 and the ink in the second ink cartridge 102 is consistent, i.e. H1=0, like this, can get by formula (6):
[0073]
[0074] That is to say, the necessary condition for ink to enter the second ink cartridge 102 fro...
Embodiment 3
[0079] Such as Figure 4 Shown is another preferred embodiment provided by the present invention.
[0080] The difference between the present embodiment and the second embodiment is that the first ink cartridge 101 and the second ink cartridge 102 are arranged together, that is, arranged together in adhering manner, so that cost and space can be saved.

Abstract
The present invention relates to the technical field of ink path circulation, and discloses an ink path circulation method for a ceramic inkjet printer and a device thereof, and a ceramic inkjet printer including the device. The method is as follows: providing a control center, an inkjet head, and a first ink cartridge , a second ink box and an ink supply box, the inkjet head is provided with an ink channel; the control center controls ink to circulate between the first ink box, the ink channel and the second ink box in sequence; the control center The ink is controlled to circulate sequentially between the second ink box and the ink supply box. Under the control of the control center, the ink can circulate between the first ink box, the ink channel and the second ink box, and between the second ink box and the ink supply box. In the two circulation paths, the second ink box is used as the Therefore, the ink can flow between the first ink box, the ink channel, the second ink box and the ink supply box, so as to avoid the precipitation of solutes in the solvent, avoid clogging the inkjet head, and will not affect the printed product.
Description
technical field [0001] The invention relates to the technical field of ink path circulation, in particular to a ceramic inkjet printer ink path circulation method and device thereof and a ceramic inkjet printer comprising the ceramic inkjet printer ink path circulation device. Background technique [0002] The inks commonly used in inkjet printing machines include water-based inks, weak solvent inks and UV inks. The density of the solute in these inks is relatively close to that of the solvent, so it is not easy to precipitate in the solvent where the solute is easy to suspend, so it is generally not necessary. Special treatment for its ink path. [0003] In recent years, people have invented ceramic inks and ceramic inkjet printers using ceramic inks. Ceramic inkjet printers have changed the defects of traditional ceramic crafts such as complex production process, single color and pattern change, and greatly improved production efficiency. However, ceramic inkjet printers ...
