Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the above-mentioned prior art solutions have the following defects: because the special ink for high-temperature glass is prone to precipitation after long-term static, the ink can be ejected from the nozzle relatively smoothly in the early stage, but in the later stage , due to the precipitation in the ink, the nozzle is easily blocked by the precipitation, which will cause the nozzle to fail to discharge ink and affect the normal operation of the equipment

Embodiment Construction

[0053] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0054] refer to figure 1 , is a method for preventing nozzle clogging on a high-temperature digital glass printer disclosed by the present invention, comprising:

[0055] S1: Obtain ink from the ink input place; obtain ink from the ink input place through the ink pump.

[0056] S2: The ink is suspended by negative pressure; after the ink is obtained, suction is generated by negative pressure, and the ink itself has gravity. After the suction and gravity are balanced, the ink is in suspension. At this time, the ink is affected by two forces. function, making the ink fully mixed inside. When the ink is in a suspended state, the minimum liquid level information and the maximum liquid level information of the ink are obtained, so as to determine the position of the ink in this segment. Then compare the ink position information with the preset position informat...

Abstract

The invention relates to the field of high-temperature digital glass printing machines and discloses a method for preventing a spray head from being blocked on a high-temperature digital glass printing machine. The method includes the steps that ink is acquired from the ink input position; the ink is in a suspended state due to the negative pressure; the liquid level of the ink is acquired and theink input amount is controlled according to the liquid level; and the ink is output to the ink input position. The method for preventing the spray head from being blocked on the high-temperature digital glass printing machine has the effect that the normal work efficiency of equipment cannot be easily affected.

Description

technical field [0001] The invention relates to the technical field of high-temperature digital glass printers, in particular to a method for preventing nozzle clogging on high-temperature digital glass printers. Background technique [0002] At present, the high-temperature digital glass printer is a machine that can directly print color patterns on the glass. Whether it is a simple block color pattern or a pattern with gradient colors, it can be printed at one time without plate making, plate printing and repeated color registration. , colorful and rich, lifelike effect, image waterproof, sunscreen, wear-resistant, no fading, simple and convenient operation, in full compliance with printing industry standards. [0003] Existing high-temperature digital glass printers generally use special ink for high-temperature glass. When ink is needed, the glass printer sends the ink to the nozzle to realize the supply of ink. [0004] The above-mentioned existing technical solutions ...
