Digital inkjet printer-how to use and maintain its ink supply tube

The printing ink supply tube of digital inkjet printer is the connection channel between the printing nozzle and the ink supply cartridge. Usually, the photo machine consists of a total of 8 ink tubes in a row, which is responsible for conveying ink to the nozzle. Don't look at a small plastic tube, its role is very important, such as printing ink breaks in the common fault of the photo machine, the ink supply is not on, the ink tube leaks, small holes, cracks, blockage, etc. Wait, it will directly affect the normal print job of the photo machine.

First of all, the ink tube of wide format textile printer should have high corrosion resistance, so the material selected for the ink supply tube must have strong corrosion resistance and toughness. It is undoubted that the ink supply tube of the photo machine needs toughness. If there is no toughness, it will not be able to withstand such a range when it needs to move back and forth. For example, the portion of the ink tube connected to the nozzle needs an unrestricted high-speed back and forth movement, which may cause the ink tube to rupture ink ejecting, leaking gas, etc., and the chain reaction may cause catastrophic consequences of the scrapping of the entire photo machine. Therefore, many photo machine manufacturers in the process of the arrangement of the ink tube of the machine, in order to better protect the toughness of the ink tube, the tank chain-type drag chain is installed on the outer layer of the ink tube, which can effectively protect the ink tube printing process in the printer. The frequent coming and coming movements cause damage to the ink tubes. In addition, the corrosion resistance of the ink tube is also important. If the ink tube cannot resist the pollution of the ink, then every part of the ink tube will not be safe in the ink supply process, and even the entire ink tube will leak due to corrosion. In the case, the hazard is even greater than the lack of toughness.

In addition to the selection of the ink tube, usually pay attention to the maintenance work in the use of the inkjet printing machine, do not disassemble the ink tube, pay attention to the tightness of the ink tube and the joint. Pay attention to check the integrity and patency of the ink tube. Do not let other inks precipitate or other impurities cause the ink to solidify and block the ink supply tube.

Therefore, the use and maintenance of the ink supply tube of the photo machine is very important, and the user of the photo machine must pay attention to it.

How to choose calender heat transfer diameter and thickness of the drum

The rollers of calender heat transfer in the drum line are mostly cylindrical parts and are usually divided into drive and moving rolls. Suitable for rotary screen printing machines, digital printers and other conveying equipment. So how do you choose the diameter and thickness of the drum line? Let me give you a brief explanation:

 Calender Heat Transfer
 Calender Heat Transfer
After the drum is formed, it is generally surface treated, and some are painted, galvanized, rubberized, chrome-plated. According to the size, it can be divided into large-sized mechanical drums, the length can reach more than 10 meters, the diameter can reach more than 1500MM, and the small flat rollers like the belt conveyor on the automatic assembly line, the length is generally 1 meter. Within, the diameter is between 159MM.

The roller diameter of sublimation heat press transfer machine selection range: 25mm, 2mm, 38mm, 42mm, 50mm, 57mm, 60mm, 76mm, 80mm, 89mm. The principle of determining the diameter of the drum is that when the tensile stress of the conveyor belt is large, the additional bending force should be smaller, whereas when the bending force is large, the tensile stress is smaller, and a smaller roller can be selected.

 Rotary Heat Transfer Machine

The calculation of the thickness for the roller heat press machine's drum usually depends on the diameter of the drum, the length of the cylinder, and the tension of the transport tape and the wear during braking. Therefore, the calculation of the thickness of the drum is difficult, and the calculated value is small, and the wear and the ease of manufacture are also considered, so the thickness of the cylinder is usually selected to be thick. After determining the thickness of the shell, we need to check the strength of the shell, but because the shell is subjected to normal and tangential loads, and the size of the load will vary along the circumference of the drum. Therefore, there is no accurate calculation method for the calculation of the thickness of the roller line drum. Although the finite element calculation can relatively accurately calculate the results, there is still a lack of a common procedure for the calculation of the conveyor roller, and only the finite element of the individual drum can be performed. Analysis, but can not analyze the calculation of the roller line drum.

What effect does dispersed sublimation ink viscosity have on the print head?

The most direct effect of the increase in dispersed sublimation ink viscosity of the printer is the flow of ink in the tubing, which causes the ink to break. The change of viscosity indirectly affects the surface tension of the ink. The surface tension of the liquid is the attraction between the molecules inside the liquid and the molecules on the surface of the liquid. When the viscosity increases, the shear resistance between the molecules and the molecules increases. It also indirectly affects the surface tension of the liquid. At the moment when the ink droplets leave the ink head, if the tension is too large, the ink droplets will not be ejected, and ink droplets will remain on the surface of the nozzle, resulting in non-particle plugging.Another characteristic of the composite solution is that the solubility of the composite solution is relatively low at low temperatures, and some solute is often present.

 Dispersed Sublimation Ink

If the dye sublimation ink appears to be precipitated, the precipitated material may also cause the ink bag and the ink head to become clogged. The most direct factor in the above cases is the temperature, which also affects the adhesion between the ink and the medium. Increasing the room temperature is critical to the stability of the ink during printing.

The same ink, the temperature is lowered, the viscosity will become larger, the viscosity is too large, and it is prone to "broken wire" at high speed printing. Many inkjet printer users will think that the nozzle is blocked, but once cleaned, it will be normal immediately. It will not repeat for a long time, and some customers will think it is a problem of ink quality. This is followed by the problem of ink absorption and drying. If the temperature is too low, it is not conducive to the absorption of ink by the inkjet coating, and it is not conducive to the evaporation of the solvent of the ink, resulting in "stacking" phenomenon. Therefore, the majority of users should maintain a suitable temperature when using in cold weather, which is conducive to the normal operation of the printer.

Under the influence of temperature, the thinness of the ink changes, which is a physical phenomenon, but the change is the form, and its essence is not changed.

The inkjet sublimation printer ink becomes thicker and the viscosity becomes larger. However, it is recommended not to use thinner or varnish to pour into the ink to reconcile and change its consistency. Because when users use these additives to adjust the ink, you do not know the total amount of additives that can be accommodated by the ink. It is easy to exceed the amount, which will affect the performance of the ink and affect the print quality.

Digital printing machine-the sequence steps to properly check printer nozzle failures

As we all know, the nozzle is the core of the digital printing machine, so its value is also very expensive. How to check and eliminate the failure of the printer nozzle?

 Digital Printing Machine
 Digital Printing Machine
When we are using the inkjet printing machine, if the nozzle can't discharge the ink, don't think about changing the nozzle first. Check it carefully to make sure that the nozzle is burnt, don't blindly replace the nozzle, and waste money. There are many factors that may cause the nozzle to fail to ink. Just a simple check, we can determine the actual situation of the nozzle of the printing machine.

First of all, when the nozzle does not discharge ink, first remove the nozzle, be careful when removing the nozzle, do not scratch the surface of the nozzle. After removing the nozzle, you can use a paper towel or towel without dander to gently touch the surface of the nozzle to see if there is any ink oozing. If there is no ink oozing out, the nozzle is internally clogged, and the nozzle can be re-cleaned. It may also be caused by a problem with the raster of the photo machine or the poor deformation of the small frame. At this time, it is only necessary to determine the cause of the problem. Normal repair or replacement of the accessories is sufficient.

If the above methods can not eliminate the problem of the nozzle, we can first check the other accessories of the photo machine, first check if the ink in the ink cartridge is insufficient, whether the ink tube is leaking or damaged. Also, check if the ink damper is damaged. If there is no problem with the photo machine accessories, the user can clean the nozzle multiple times, then increase the print accuracy mode, and then print the test to see if it can print normally. If it can print normally, it means that some nozzles are damaged, but it can be used normally if it is printed in high-precision mode. If it still cannot be printed normally, it means that all the nozzles of a certain color are burnt out and cannot be used any more, then it needs to be replaced.

The nozzle is the core of the large format digital printer, so its value is also very expensive. Please refer to the above suggestions when there is a problem with the photo machine nozzle.

Printing ink-how to check quality to judge whether it is inferior ink

 Printing Ink
 Printing Ink
It is well known that the use of inferior printing inks is very harmful to the nozzle. Burning the printer nozzle not only affects the printing results but also increases operating costs and damage to the printer equipment. The cheapest to buy a photo machine is thousands, expensive tens of thousands or even hundreds of thousands. If you bought a cheap inferior ink, it may be caused serious damage to the equipment, it is really worth the loss. Therefore, to remind the majority of photo machine users, we must buy regular factory ink or use the original ink of the printing machine. How to distinguish the quality of ink?  Here is a brief introduction to how to distinguish the quality of ink.

The method of distinguishing ink quality:

1. With a matchstick soaked incompatible printer ink, the line is uninterrupted on the paper. The finer the line, the more broken the line, the darker the ink, the better the quality.
2. You can use the inkjet printing machine to print some grid and thin lines. If there is a color cast or short line, it is good to show that the ink quality is poor. Of course, it is necessary to clean the nozzle before printing to ensure that it is not the fault caused by the machine so that it can be tested most accurately. However, this method is used to waste ink. Secondly, if the printer ink quality is poor, the nozzle should be re-cleaned, so this is not the best method.

3. Actual print inspection, first add the inkjet ink to the empty ink cartridge as required (the ink cartridge electrode must be good). Then install the ink cartridge with the ink to perform inkjet cleaning to see if the self-test printing is normal (if the self-test is not passed, it is necessary to immediately clean the improper ink and change the ink). Next, use WORD to typeset, set the back background of various 0 fonts and "screen". Finally, the printing test is carried out on paper by the LQ model/HQ printing method, and good ink should have no problems such as the lack of pen drawing and color cast.

Therefore, remind the majority of users of inkjet photo machine, must buy regular factory ink or use original ink.
