In recent years, inkjet printing technology in a wide range of industries, inkjet printing to facilitate the production, but how to use a good
inkjet printer, how to strengthen the inkjet equipment, process management, good professional reserves and so on , Are the current must pay attention to the problem.
First, the management of inkjet professional technicians
Inkjet than the roller, screen printing in the personnel skills on the higher requirements, in addition to understand the basic operation of inkjet, but also have a certain computer, transfer capacity, have a stronger sense of responsibility, so inkjet personnel management should focus on In the skills training, discipline system constraints.
1, inkjet technicians should be familiar with the basic mechanism of inkjet equipment and operation, know how to change the ink process, proficient, skilled PS version, the correct maintenance and maintenance of inkjet equipment. Can solve the inkjet printing process appears drawing, drop ink, ink, ink, hanging ink and other common problems, can correctly identify and deal with inkjet equipment alarm failure.
Training work mainly for the above issues, and must be practicing training, after the practice of assessment can be posts.
2, personnel discipline and system management. In addition to the personnel who have been allowed to access, other personnel without the consent of the workshop manager to prohibit access to the inkjet room, inkjet printers to supervise the management of responsibility.
3, the inkjet software parameters in addition to the designated training of the inkjet in charge of the staff, the rest of the operator shall not be free to prevent changes to the parameters of inkjet equipment to work properly. Regularly back up the configuration files on the machine so that the system can quickly restore various settings and restore production due to an unexpected crash. Inkjet device USB interface prohibit the insertion of U disk, generally only inserted through the special anti-virus processing U disk, otherwise the system is infected by the virus, easily lead to computer operating system and inkjet software system failure or error.
4, equipment failure, must be handled by professional maintenance personnel. Machine failure, or pull the line in the cleaning nozzle is invalid, the immediate shutdown notice inkjet management.
Second, the management of inkjet ink
1, manage the ink into the factory acceptance. Each batch of ink into the factory should be sampled to check the ink color, ink viscosity, the proportion of ink, if the three indicators and the standard sample no difference, you can think of this batch of ink qualified, of course, there are other indicators of ink, but the manufacturer No need to put the appropriate testing equipment for testing.
2, the management of the use of ink. In addition to the provisions of the ink, but also should be careful not to add the wrong ink, add the wrong ink after the re-cleaning takes a long time, delay production. If the ink in the ink tank for more than a month did not run out, should promptly update the ink, otherwise it is prone to plugging and so on.
3, manage the precipitation of ink problems. Because the ink is composed of inorganic colorants, organic solvents, dispersants and other ingredients, long-term after the toner particles will settle to the bottom of the container to form pigment layer, known as precipitation, precipitation, the ink viscosity will be reduced, hair color will Weakened, other indicators will change, but the ink after standing precipitation is a normal phenomenon, is inevitable.
Properly manage the ink, reduce the precipitation, pay special attention to the following:
1) Store the ink in an indoor temperature of 15 to 25 ° C.
2) as soon as possible in the shelf life (within 6 months) run out, the sooner run out, the lower the risk of ink problems. And should be planned in advance warehouse warehouse ink inventory, should not be stored too much, and arranged to store the ink on the machine once a week to shake the ink to reduce the settlement, is conducive to the use of production, re-production should be 10 to 15 days before the single stocking.
3) ink before use, the application of red ink and redistribution, shake ink time should be more than 30 min, which 10 min roll once the ink bottle. After shaking ink, do not rush to open the lid, should be standing for more than 10 min, so that the bubble fully eliminated. When opening the lid, pay attention to aluminum foil do not fall into the ink tank.
Third, the inkjet printing process technology management
Inkjet production on the stability of the field process has a relatively high demand, need attention. Usually require pre-printing blank temperature can not be higher than 45 ℃, and glaze volatilization of water vapor should be as low as possible, or easily lead to hanging ink so that ink drops; too high billet temperature and water vapor will lead to nozzle, board life shorten.
Inkjet process management should pay attention to detail management and quantitative management, after the first understanding of the production number, check the standard version and inkjet effect, check the belt speed, jet height and other parameters, if in doubt immediately asked the shift staff, check the amount of ink, Must be added in time.
Check the temperature of each cartridge once every 1 h, whether the vacuum degree is different from the set value. Check the flow of the natural return pipe of each cartridge once every 1 h, and must flow above half the tube. Every 1 h to clean the belt scraper once, to prevent the accumulation of dust affect the normal operation of the inkjet. Strictly monitor the printing effect, every 1 h on the printing effect, pattern, color and sampling once and make a record. Every 2 h must wash the nozzle once, there is a serious increase in the number of cleaning line cleaning. In normal production, the inkjet machine must use the automatic flash spray function to protect the nozzle.
Fourth, the management of inkjet printing equipment
Scientific management of inkjet equipment, both to extend the service life of equipment, can reduce the occurrence of equipment failure, improve production efficiency. Ceramic inkjet equipment management, the main focus on the nozzle maintenance, filter replacement, ink system cleaning management, maintenance management, inkjet working parameters and software management, fault management and so on. Specific details include the following:
1, nozzle maintenance. Production and shutdown should pay attention to the maintenance of the nozzle, the production should be automatically every hour an hour cleaning nozzle, for exhaust, tube, wipe the nozzle and other manual operation, to do the whole dust, Electrostatic protection, to avoid improper operation caused by dust adsorption to the nozzle caused by plugging and other defects. Wipe the nozzle should wear protective gloves, the use of infiltration cleaning fluid dedicated clean cloth, spray nozzle in the same direction of the same direction to wipe. Wipe once every wipe to clean the clean part with a clean cloth. Spray hole parts and nozzle sheath to separate the wipe, is strictly prohibited by the jacket to the nozzle part of the wipe.
Routine maintenance should also pay attention to the overall cleaning of the nozzle clean, in addition to the nozzle area is the most important, the non-working surface of the rack, nozzle shell, board, etc. should also be cleaned up in time. Pay attention to check whether the inlet and outlet ink leakage, leakage ink, bubbles, ink precipitation and other anomalies. Cleaning operation to disconnect the nozzle power, let go of the body of static electricity, good dust control measures.
2, scientific and rational use of filters
1) Regularly clean the entire ink system. Running time after a long ink tank, filters, pipes, nozzles, etc. will have a certain ink particles deposition adsorption, timely and thorough cleaning is conducive to the overall operation of the inkjet and post-production stability. Need to pay attention to the cleaning must be completely clean, or may be due to sediment loose and not clean up lead to nozzle plugging, the effect is not good. According to the actual situation of ceramic production line, usually in the end of the kiln overhaul when the thorough cleaning ink Road.
2) regular replacement of the filter, usually every 2 months to change once. Filter is an important part of the normal operation of the nozzle protection, the use of a long time there will be part of the residue deposition, affecting the efficiency of filtration, increase the ink pump, circulating pump work intensity, easy to damage the ink pump and circulation pump, Leading to lack of ink.
3) do downtime maintenance
Inkjet machine is not in production, in addition to automatic micro-spray and other maintenance measures, the manual should be manually squeeze ink cleaning 2 to 3 times, continuous high-dimensional maintenance with 20 to 30 times. At the same time check the main technical parameters and ink system, print the state diagram to check the status of the nozzle, so that problems in a timely manner. For a long time do not produce the ink should be appropriate to reduce the operating temperature. Reduce the amount of ink stored in the ink tank, regular printing consumption and then add the amount of new ink.
Fifth, the use of inkjet environment management
In order to reduce the environmental dust on the nozzle pollution, the need for inkjet room environment for strict management.
1, inkjet room need to maintain a positive pressure. Positive pressure environment is conducive to reducing the concentration of environmental dust, according to the relevant personnel pointed out that the best positive pressure of the inkjet room can be expressed by a basic formula: inkjet room required the best positive pressure air volume = ink waste ink Fan air volume +1000 m3 / h (fixed positive pressure), the greater the room volume, positive pressure required air volume of the fixed value is a corresponding increase.
2, to keep the room temperature at 18 ~ 24 ℃, humidity in the 40% to 65%. Good temperature and humidity, is conducive to equipment cooling and inkjet system stable work.
In order to maintain a good inkjet environment, we must also pay attention to the hygiene and cleanliness of the inkjet room, such as into the inkjet room to be replaced slippers, non-inkjet staff, without permission shall not enter; each class on the outside of the inkjet Wipe, every time dragging the ground; regular fan, air filter, air conditioning filter maintenance.
With more and more inkjet machines put into use, the factory in the follow-up management must be further improved. "Want to do good things must first of its profits," the scientific management of inkjet will become more important.
