A nozzle control method, device and computer-readable storage medium

Abstract

A spray head control method, comprising: joining a first spray head, a second spray head, a third spray head and a fourth spray head, wherein the first spray head and the second spray head are transversely joined, the third spray head and the fourth spray head are transversely joined, the first spray head and the third spray head are vertically joined, and the second spray head and the fourth spray head are vertically joined; proportioning and completing data printing tasks by means of the four spray heads according to four groups of timing sequences, wherein a first nozzle and a third nozzle of the first spray head print first data at a first moment, a fifth nozzle and a seventh nozzle of the second spray head print third data at a second moment, a second nozzle and a fourth nozzle of the third spray head print second data at a third moment, and a sixth nozzle and an eighth nozzle of the fourth spray head print fourth data at a fourth moment. By means of rationally controlling spray heads and nozzles, the full quantity of nozzles of the spray heads may be used, and printing speed and printing quality are not reduced due to a spray head alarm; meanwhile, the control method may guarantee that the spray head stops in case of an overheating alarm, and may guarantee that the movement of a medium is not interrupted, thereby improving the printing efficiency and usage ratio of a printing device.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a method for controlling a nozzle. Background technique [0002] In the prior art, in the operation and use of industrial inkjet printing equipment, the application of unconventional printing is increasing day by day, such as the production of liquid crystal screens and the production of thin film circuits. As the batch production method of graphene slurry becomes more and more mature, the production of graphene film (non-single-layer film) by jet printing has also become a reality. [0003] Graphene films have many advantages, such as good thermal conductivity and strong electrical conductivity, and the important prerequisite for these advantages is that the thickness of the film should be thin. Industrial nozzles can realize high-precision, high-speed, and small-dose liquid injection (ink-like solutions that meet the requirements of nozzles). The graphene slurry is configure...

Problems solved by technology

[0006] In order to solve the problem in the prior art, the overheating method of the print head is generally that the sensor detects that the inside of the print head reaches the preset temperature threshold, and the printing will be slowed down or stopped, and finally the equipment will be shut down, whether it is to stop the printing or shut down the equipment. All will cause waste of time or printing substrate technical defects, the present invention proposes a nozzle control method, the method includes:
