Engaged in the outdoor industry these years, from gas spray to Piezoelectric spray, from unreachable prices to parity status, from huge profits to today's small profits. Throughout these years, how many people have gone through, talked about and talked about, and how many people can understand the bitterness of customers.
In today's low-margin era, how to save your every penny and how to make your equipment bring you greater profits is something everyone is thinking about, but how effective is it. Obviously, extending the service life of the nozzle is one of the means to reduce costs. I visited a lot of customers, and summed up a little experience from their various usage situations. I hope to help my colleagues.
1. Environment:
Why put environmental requirements first? Customers who have been using the spray head for more than half a year with a continuous line, their environment is tidy, the fuselage is not sticky, and there is a set of reasonable management system. I once met such a customer, let ’s not talk about the environment first — it ’s impossible to step in, the machine is covered with dust, but the customer and the staff also said in unison, it ’s okay, dirty, messy, without affecting the machine The service life of the nozzle. This is probably a part of the typical Chinese. Fortunately, such customers are very few. They may not realize that dust can easily enter the main ink tank and then the sub ink tank, and then enter the nozzle, affecting the printing effect of the nozzle and shortening the nozzle. life. It is conceivable that no machine like this has a service life of more than three months; at the same time, many customers are lost.
A year ago, Mr. Zhang, a customer of Kaiping, told me this sentence: The machine is my lifeblood, and it cannot be broken (stopped). If it is broken, it means that my wealth is also broken. Moreover, many customers have such a consensus that to cherish the equipment and treat the equipment is tantamount to treating yourself. Therefore, their sprinklers are used for more than one year, and even a few are used for about two years. Such an example is worth emulating and learning.
2. Operation
Some operators do not listen carefully during training, and do whatever they want during operation. It ’s quite reasonable to say him. Some bosses have no control, some bosses think that such trained people can't be dismissed, otherwise there will be no operators, which brings a series of consequences. I visited a customer who used a roll of paper to wipe the nozzle. The nozzle part of the xaar nozzle should not rub against any objects, so it is easy to scrub the nozzle surface. Moreover, there are many fine fiber hairs on the surface of the toilet paper, which are easy to enter the nozzle, and the fine hairs are easy to hang on the nozzle surface. Cause clogging and dripping ink, which affects the printing effect. Therefore, it is very important to study and listen carefully, and operate the equipment in strict accordance with the requirements.
Third, auxiliary accessories
Every accessory on the machine has its purpose, do not remove it at will. The customer I mentioned earlier has no air filters on their main and secondary ink tanks. Various particles in the air easily enter the ink. No one can guarantee that there is no dust in his indoor air. The air filter is used to filter the air and cannot be thrown away at will. If it is blocked or damaged, it should be replaced immediately.
Some brand machines have a ground wire and heat sink on the nozzle. The ground wire is to protect the spray head and prevent static electricity. A customer in Fangxian, Hubei, bought a domestic machine nozzle without a ground wire, and burned three nozzles within half a year. I did not agree to purchase the nozzles of my company because the voltage of the nozzles used by each manufacturer is different Yes, the use of other spray heads can damage the spray head and the equipment itself. In addition, a constant temperature is required when the nozzle works (see the introduction of the nozzle by Xaar Company for details). The heat generated by the nozzle is mainly taken away by the ink jet and then discharged by the heat sink. I often hear and see that some customers burn out the nozzles. This is actually related to the voltage level of the nozzles, whether they are connected to ground, or whether they have heat sinks.
Here, it is very important that the ground wire of the device. The particles in the air have static electricity, the static electricity generated by the friction between the medium and the device, the device itself has some leakage, etc., which causes the body to be charged. If it is not grounded, the static electricity cannot be eliminated, and it is easy to damage the main accessories such as the nozzle and the main board. .
4. Ink
As we all know, the quality of ink directly affects the picture quality and the print head. At present, domestic inks are mainly used in the market, while the price and quality of famous brand inks are different. Cheap prices are not equivalent to reducing costs, sometimes causing nozzle clogging, screen printing interruption, scrapping, poor color returns, etc., thereby wasting more manpower and material resources, increasing costs and causing unnecessary losses. This is the experience of many customers themselves. Therefore, it is best to use the ink recommended by the equipment manufacturer (agent), because these inks have undergone rigorous and long-term testing, which guarantees the equipment and the nozzle.
5. Maintenance
Originally I put maintenance in the operation column, but thinking about its independence and importance, I decided to put it at the last point. In fact, the maintenance of the nozzle is very critical. There are several types of inkjet printers with automatic cleaning systems. Compared with the overnight shutdown of the nozzle with ink, the service life of the nozzle is very different.
Before the equipment is shut down and powered off, the nozzle must be cleaned, and the nozzle should be placed on the moisturizing sea surface pad, so as to ensure that the condition of the nozzle is the same as the previous day, and the picture quality is the same.
Relatively, there is no cleaning system equipment (such as a 3.2-meter large Inkjet Printer). When the machine is stopped, be sure to apply cleaning liquid to the surface of the nozzle and wrap it with cling film. The cling film is close to the nozzle, which reduces the volatilization of the cleaning liquid and ink. To a certain extent, extend the service life of the nozzle.
If you will not use it for a long time (such as May, National Day, Spring Festival and other long holidays), you must remove the nozzle from the device, soak it in the cleaning solution, and wrap the container with plastic wrap to prevent the invasion of dust and the evaporation of the cleaning solution.
