Daily maintenance tip of roller heat transfer machine

If the machine is used for a long time without maintenance, it will end its life prematurely. Paying attention to daily maintenance is an important way to extend the life of the roller heat transfer machine.

Daily maintenance tip of roller heat transfer machine

👍 Tip 1

Regular inspection of the roller thermal transfer machine can ensure the stable operation of the roller thermal transfer machine. During the use of the roller thermal transfer machine, it is also necessary to frequently check whether the ink supply pipeline of the roller thermal transfer machine is cracked or damaged. If found, it should be repaired or replaced as soon as possible;

👍Tip 2

Clean the roller thermal transfer machine in time, and clean the dust inside the cabinet regularly. Do not use inferior ink;

👍Tip 3

Pay attention to the use of ink for roller heat transfer machines. Different roller heat transfer machines need to use matching inks, and the inks cannot be used in common. When using it, you must pay attention to the distinction, and don't make mistakes. Pay attention to see if the ink model is the same as the previous ink model;

👍Tip 4

Regularly check the shell of the roller heat transfer machine to prevent the corrosion of the outer shell caused by ink leakage. Protecting the shell can effectively extend the service life of the roller heat transfer machine. Although most of the roller heat transfer machines now have a corrosion-resistant shell, long-term immersion in ink or cleaning fluid can also cause damage to the roller heat transfer machine. Therefore, when ink or cleaning fluid sticks to the case, it needs to be cleaned in time;

👍Tip 5

In terms of oil circuit, the mechanical lubrication of the roller heat transfer machine is an important part of equipment maintenance. Keeping the oil circuit of the printing machine unblocked is related to the lubrication of the moving parts of the whole machine. The oil must be changed regularly and the oil filter device must be cleaned, so that the oil flowing into the pipeline does not contain impurities, and part of the oil circuit is prevented from being blocked. Especially the needle roller bearing of the supporting roller of the unit, if there is no lubrication and cooling of the oil, it will cause long-term dry friction between the bearing and the roller shaft. When an abnormality is found, the shaft and the inner ring of the bearing have been glued, the lighter case is replaced with the inner ring, and the heavier case is the roller. The shaft is severely damaged.

👩‍🎓Knowledge of roller heat transfer machine heat transfer steps

1. Ink

When printing, the viscosity of different inks is directly related to the heating temperature, and the heating temperature and the viscosity of the ink should be strictly controlled. Generally, the closer the ink is to this state, the better the thermal transfer transfer performance.

2. Thermal transfer paper

The substrate of thermal transfer media transfer paper is generally divided into paper substrate, polyester substrate and celluloid substrate, and different substrates have different properties. For example, the material of the thermal transfer paper must be able to withstand the influence of the transfer temperature of the thermal transfer equipment and keep the properties unchanged.

3. Thermal transfer printing head

The speed of thermal transfer printing depends on the time required for each line of graphics and text. Therefore, the thermal transfer print head and the transfer paper should have good heat transfer properties, so that the heat generated by the heating element can quickly pass through the protective layer, the transfer paper substrate and the gaps and then transfer to the surface of the substrate to ensure that the ink has Sufficient transfer time.

4. Substrate

Substrates with a little rough surface have better print quality, which is a significant feature of thermal transfer. Because the rough surface of the substrate indicates that the substrate has a larger surface energy, the ink on the transfer paper can be transferred to the substrate well, and the ideal level and tone can be obtained; but too rough will affect the ink quality Normal transfer is not conducive to the realization of the printing process.
