How to maintain the white ink direct injection machine

In the past three years, the government hasWhite ink direct injection machineThe requirements of printing and dyeing factories are becoming stricter. Every factory that meets the standard must have a certain proportion of high-speed industrial digital printing machines. At the same time, the government has also issued various tax policies to encourage the use and research and development of digital printing machines. The textile industry needs sustainable development, and digital printing technology is very necessary.

Requirements for industrial sprinklers

Digital printing has been in development for more than 20 years, but high-speed digital printing machines have really begun to be accepted by the market only in a short period of 2-3 years in recent years. For digital printing technology, now is the breakthrough period of rapid technological development, and the joint efforts of nozzles, inks, machinery, and integrators are needed to accelerate the maturity and leap of technological improvement. Among many factors, the sprinkler is the leader of the entire technology, so it is even more important.

So, what kind of nozzle can meet the needs of high-speed industrial digital printing? Through research, the following three points are the key:

(1) Durability and long service life:

The nozzle is recognized as the most expensive component in the whole machine. The more high-speed production, the more specifications and numbers of nozzles. Once the loss of cost is great, printing and dyeing factories require nozzles to be more durable. It is well known that Dimatix nozzles have the characteristics of high full-load cycle, long life, and scratch resistance. Starlight nozzles are the first nozzle on the market that can be disassembled, repaired and replaced.Digital direct injection equipmentThe factory bids farewell to the era of buying new nozzles once there is any problem with the nozzles.

(2) Realize uniform and stable printing at high speed:

In order for the printing and dyeing factory to exchange the digital printing machine from the inherent production line, it must achieve at least acceptable speed and stability. According to the survey at this year’s ITEX exhibition, printing and dyeing factories generally accept digital printing speeds of 30-40m/min. But they also emphasized that in printing, to maintain the consistency of inkjet density and stable printing.

The ejection speed of the nozzle and the ability to cooperate with the ink are very critical. For the starlight nozzle, the printing speed of 30-40m/min is not a problem, and the equipment factory has easily achieved it. For textile water-based inks, especially pigment inks that have received widespread attention, Starlight nozzles are specially designed for dual ink internal circulation. Each of the 1024 nozzle holes on a single nozzle is circulated separately to keep the ink flowing at any time. Take away bubbles and reduce precipitation.

During long hours of work,Piece printing machineThe ink can print smoothly and stably, reducing the possibility of wire drawing and clogging, and reducing maintenance frequency. And even if the machine rests overnight, and the internal circulation is turned on the next day, the ink can work normally immediately, reducing the time for starting up preparation.
