Reasons and solutions for pulling the UV flat panel
The situation of the cable pull in the UV flatbed printing and printing is a problem that many users and models may have. The occurrence of these problems does not mean that there is a problem with the conventional UV tablet. It is necessary to repair the machine, but some small The problem, you can adjust the machine by yourself, or change the ink, change the paper, for the UV tablet pull, we found the reason and solution for everyone:
One: regular cable
Auxiliary equipment abnormal nature pull line: refers to the lack of ink between the entire nozzle or a continuous number of spray points. The reason for this kind of pulling is that the nozzle does not emit ink or the ink of the UV flatbed printer is insufficient, or the ink is stuck on the nozzle due to the instability of the UV flatbed printer. However, most of these pull wires are usually caused by nozzle circuit boards or negative pressure pumps and ink supply pumps. In general, replace the corresponding circuit board and vacuum pump. Of course, there is also a way to increase the frequency of the ink supply pump and periodically replace the filter to eliminate the abnormal nature of the auxiliary equipment.
Two: feathering pull line
Feather pull line: This kind of pull line is generally realized by the arrangement of the nozzles in the direction of the apparently equidistant arrangement or the white line. The state diagram of the print head can observe that the stitching positions are overlapped, spaced or poorly feathered. Such a pull wire only needs to check and adjust the belt to make the UV flatbed printer operate normally, and adjust the nozzle's spray point transfer position or adjust the feathering to solve. However, it should be noted that in the case of different grayscale graphics printed, the degree of feathering required for the same handover location may be different.
Three: blocking cable
The pull wire of the plugging property: the UV flatbed printer pull wire of this nature is generally a "white line" of a certain color channel fixed position, and there are many "white lines" in severe cases. The reason for the blockage is that there are many aspects. For example, the operation mode and environmental factors will cause the pull line of the plugging property. The uv ink shakes the ink unevenly. During the process of adding the uv ink, some impurities are introduced. When the wipe is cleaned, the nozzle is not standardized, so that the dust of the environment adheres to the nozzle. . Use a sponge to clean other inks such as ink or glaze powder when cleaning and maintaining the nozzle.
Tips:
When users use UV flatbed printers, pay more attention to observe, pay attention to daily cleaning to reduce the occurrence of cable problems, even if it does not need to be anxious, according to the above method, your own operation can be quickly resolved.
