Photo printer-ambient temperature and cleaning method affect the life of its nozzle

The viscosity index of the ink will change with the change of the ambient temperature, and the corresponding working voltage of the corresponding photo printer nozzle will change accordingly. Otherwise, the injection of the nozzle will be unstable, and the phenomenon of disconnection and ink breakage will occur easily. When the temperature is high, the viscosity of the ink is lowered. At this time, the working voltage of the nozzle should be appropriately reduced. Otherwise, it is easy to form a bubble inside the ink tube, causing no ink to be ejected from the nozzle, resulting in a white line of the screen. Conversely, when the temperature is low, the viscosity of the ink will increase. If the working voltage of the nozzle is not adjusted, the ink will accumulate inside the ink tube. In a short time, it may be seen as a virtual spray. After a long time, the nozzle is easily irreversible. Damage, serious damage to the nozzle hole. The nozzle works from the beginning, the temperature of the nozzle plate is relatively low, but with the continuous operation of the piezoelectric ceramic, the temperature inside the nozzle plate will gradually increase, and as the ink is continuously ejected, part of the heat will be taken out. Finally, the working temperature of the nozzle will be constant at a fixed range. If you start from the beginning of the nozzle to the constant temperature stage, you need to adjust the nozzle voltage according to the nozzle plate or the ink temperature to ensure the normal operation of the nozzle. Otherwise, the nozzle will be unstable.

 Photo printer

For the processing of the digital textile printer nozzle not printing, in the actual printing process, the width of the screen often appears to be smaller than the design width of the nozzle, then the portion of the nozzle that does not come out will not be inkjet. If the ink is sprayed, it will cause a large amount of ink residue to be transported. If the cleaning is not clean, the belt life will be reduced. In addition, because of the interval between the nozzle and the belt, the small ink droplets ejected will drift around with the airflow, flying around the nozzle, and even the control circuit on the nozzle, affecting the normal operation of the circuit part, and being inhaled by the staff is also a great hazard. For this reason, the excess nozzle will not work. If the excess nozzle does not work, the ink in the nozzle nozzle and the ink on the nozzle surface will inevitably cause the ink to dry on the nozzle pipe and the nozzle surface due to volatilization, and the nozzle is blocked. Normally, the nozzle should be cleaned at regular intervals so that the ink in the nozzle tube is in a flowing state.

 Inkjet printer

The effect of the cleaning method on the nozzle. When the ink is ejected normally, the ejected ink droplets will have satellite points, and the satellite dots will adhere to the nozzle surface. As the printing time increases, the satellite dots will increase, thereby forming ink beads on the surface of the nozzle film. If there is damage near the nozzle hole of the nozzle plate, it is not conducive to the diffusion of the ink beads, it will accumulate around the nozzle hole, causing the nozzle hole to be temporarily blocked, and no ink is ejected; if it is not cleaned in time, or the cleaning is not complete, it is possible Causes the ink to dry on the surface of the mouth, speeding up the blockage of the nozzle orifice. In addition, because the cleaning method is not correct, or the cleaning material is incorrectly selected, the nozzle film may be scratched, and the nozzle may be scratched, as if the water is discharged from the faucet. If the water outlet of the faucet is damaged, then The water flow coming out is not under direct current, but is biased out. The same is true for the nozzle inkjet water. Once the nozzle hole is destroyed, it will directly cause irreversible damage to the nozzle. After the nozzle hole is destroyed, the ink around the nozzle hole is more likely to accumulate ink, block the nozzle hole, and shorten the service life of the nozzle. In addition, it also causes oblique spray, which reduces the print quality of the screen.

From the application of the industry, the nozzle of large format digital printing machine manufacturers must have targeted development, in order to better adapt to the industry applications, equipment manufacturers must also have a wealth of nozzle experience, to ensure the cooperation of nozzles and ink, professional manufacturers can provide complete nozzles Maintenance program to extend the life of the nozzle.

Textile printer is garbled or fan does not turn, what should we do?

In recent days, I have seen a lot of people rushing to ask questions about the failure of the textile printer, mainly because of the garbled phenomenon of the photo machine and the fact that the fan of the printer does not turn. Today, I have probably sorted out some related solutions for your reference. I hope I can bring you some help.

There are two main situations in the garbled version of the inkjet printing machine: one is that the photo machine is garbled, that is, the image that is printed is completely inconsistent with the original image, and the deviation is very large. Another situation is that the display of the photo machine is garbled.

 Textile printer

If the printer is garbled, it can be solved according to the following conditions. First, if the real machine uses a parallel port print line, make sure that the parallel port mode of the computer is ECP. If the mode is correct, check if the data cable or the print cable is normal. If there is any problem, please replace it in time. In addition, there may be a problem with paper feeding. Check if the paper is normal and whether the paper is correct. If these are normal, it may be that the computer software or the system has failed. You can reinstall the Montevideo software or replace the computer and test it. If it still doesn't work, then there may be a problem with the motherboard of the photo machine, so you need to replace it in time.

Another situation is the problem that the photo display is garbled. First of all, please pay attention to whether it is in English. If this is not the case, please check the static electricity or ground connection, or the plug on the screen and the motherboard are not plugged in, just plug it in again. You can also use alcohol to wipe the memory and decryption cards to improve the situation. If it doesn't work, it's probably a display problem, and you need to change the display in time.

 Digital printer

Finally, let's talk about the fan problem of digital inkjet printer. Generally, there is a problem with the connection. You can re-plug it or change the root line. It may also be a problem with the socket. Put the fan in another slot and test it. If it can be used normally, it proves that there is a problem with the socket. Of course, if it can't rotate normally, most of the fan is broken, you need to replace it. In some cases, the fan is faulty due to the motherboard problem. It is best to ask the technician to check it and determine if the motherboard needs to be replaced.

For the time being, I have summed up so much for everyone. I hope that I can help you. I also remind everyone to be careful when using it, so as to avoid unnecessary problems and affect work efficiency.

Digital printer printing speed is slower after system is modified,how to do?

I believe everyone knows that the continuous ink supply system used in digital printers on the market is also a common trend. The development of the continuous supply system is relatively mature. The most important use is convenient and fast, which can greatly improve the work efficiency of the photo machine, thus deeply welcomed. However, some users also directly modify the continuous ink supply system, so there is a situation in which the printing speed is reduced after the system is modified. I also want to know that it was originally intended to improve the efficiency of work, but it was not enough to lose the result. Let me share with you today the solution to this situation, I hope to help you make up for this advantage.

 Digital printer

Generally speaking, when the continuous ink supply system of digital inkjet printer is modified, the original ink cartridge will be modified. In this case, it will inevitably
burden the word car. When the load is too heavy, the car will run slowly, and the overload will lead to accelerated aging of the photo machine and increase the friction between the car and the connecting rod, resulting in a lower working speed. The car could not be reset and could not be used completely.

To solve this situation, there are the following methods:

The first is to replace the motor. When the hose of the continuous ink supply system rubs against the wall of the printer, the load of the electric motor will gradually increase. This will cause the loss of the motor for a long time, so it needs to be replaced. The second is to lubricate the connecting rod. Sometimes low-speed printing is because the use time is longer, the friction between the carriage and the connecting rod inside the machine becomes larger, and the increase in resistance causes the electric motor to run slowly, so that the lubrication of the connecting rod can solve the fault. Finally, pay attention to the aging of the belt of the printing equipment. The frictional force of the driven gear connected to the motor accelerates the aging of the belt of the printer. At this time, the cleaning and lubricating machine can avoid the failure of the belt aging.

 Inkjet printer

It is worth noting that you should be careful to connect the wires of large format digital printing machine, and do not cause the pulling of the car to be blocked. Since the internal structure of different photo machines is somewhat different, and there is no support for modification and supply, it is crucial that the wiring problem becomes a modification. I hope these methods can bring you some reference!

The roller heat press machine-do you know how it is pressurized?

The installation of the multi-function roller heat press machine is divided into a lining cloth and a white cloth. The lining cloth adopts a tight type, and the white cloth is mostly loose, and is fed by super-feeding, so that the fabric is suspended in the shape of the cloth ring, and the speed of feeding the super-feeding roller is controlled by the photoelectric tube to ensure the white cloth is relaxed. The state enters the front of the car, making the fabric tension different and achieving excellent printing results. The lining-free printing machine only has a white cloth installed in the cloth.

 Roller heat press machine

Pressing mechanism of the garment rotary heat transfer machine: the pressing mechanism applies pressure to the flower cylinder through the bearings at both ends of the flower cylinder shaft. In order to make the printed pattern clear, the left and right prints are averaged, and the pressure must be applied properly. The pressure is too light, and the printed pattern is light in color, so that the bottom is too thick, it will be ambiguous, and it will additionally increase the power loss and increase the wear of the parts. Usually, the thick-lined, large-patterned flower cylinder and the pressure roller as a light plate are lightly pressed, and the flower tubes of fine lines, clouds, and snowflakes are heavily pressed.

The line pressure ranges from 100 to 600 N/cm and is commonly used from 200 to 400 N/cm. The total pressure of each flower tube can reach 2 × 104 - 8 × 104N depending on the length of the flower tube.

In addition, the pressurization mechanism should also meet the following process and operational requirements:

 Heat transfer machine

1. The calender heat press can not only control the advance and retreat of the flower tube and the bearing seat, but also precisely adjust the pressure on the left and right sides respectively.
2. The pressurizing system should be flexible. When the joint of the cloth passes through the pressing point or the shaft is bent, it can act as a buffer to reduce the pressure passively.
