Practice has proved that an automatic cleaning plastic head system is installed beside the Hot Air Stenter Machine device, which will greatly improve the quality of printing. Because in the printing process, it is impossible for all the ink on the surface of the rubber head to be transferred to the substrate, the ink remaining on the rubber head will slowly change, which will form the edge of the pattern trace on the surface of the rubber head, resulting in a clear degree of clarity. reduce. There are two ways to deal with this kind of problem: one is to improve the deinking level of the rubber head; the other is to add an additional automatic rubber head cleaning system. However, it is not so easy to improve the deinking level of the rubber head, so most of the solutions are to install an automatic rubber head cleaning system. The feature of the automatic rubber head cleaning system is that in the process of retraction of the pad printing rubber head, there is one more step to switch the ink on the rubber sheet than the general Hot Air Stenter Machine, and the remaining ink on the surface layer will be cleaned. clean. Multi-color chromatic printing, the automatic cleaning of the plastic head system can be clearly seen in the correctness of chromatic pad printing. For example, multi-color chromatic printing involves the printing of dots, and the dots become larger. Obvious control will be achieved. Therefore, the automatic cleaning plastic head system of Flat Screen Printing Machine Factory is essential for the application of high-end precision Hot Air Stenter Machine.
