Open Type Rotary Screen Printer usually consists of four parts: the feeding device, the printing head, the drying device, and the falling device. Although it looks very simple, we need to know what are the common problems of the rotary screen printing machine and make it easy to plan.
The common problems of the general Open Type Rotary Screen Printer are relatively easy to solve. The summary of the Chinese printing network mainly has the following eight points:
First, the white cloth of Open Type Rotary Screen Printer is poorly pasted.
Found this situation, the first step to do is to check whether the position of the rubber roller is aligned with the position of the white cloth, whether the rubber knife edge is flat, and whether the glue concentration is appropriate, so that the problem of poor white cloth sticking can be basically solved.
If the use of thermoplastic plastics causes poor adhesion of white cloth, it is necessary to check whether the glue is even or leaks. If there is no problem, check whether the heating temperature of the curved plate meets the requirements, and also It should be noted that the speed of the car is appropriate.
Licheng believes that it is also necessary to pay special attention to whether the surface of the plastic layer has been touched by hand or stained with oil.
Second, printing volume is too little or too much, and the pattern is blurred.
There is usually only one solution to this situation: adjust the position of the scraper and the pressure of the scraper. What needs to be known is that when the blade is tilted backwards, the amount of ink is increased, and vice versa.
Third, printed patterns have strips
Solution: Check that the doctor blade is straight and that the blade has wavy wrinkles.
Fourth, the blanket of Open Type Rotary Screen Printer is laterally offset.
Solution: adjust the tension of the blanket and the guide controller of the blanket or adjust the distance between the stop point of the guide controller and the micro switch (generally 2~3cm). If there is a horn sound, stop immediately and trace the cause until Until the troubleshooting, China Printing Network reminded that it can not continue to operate.
Fifth, the circular screen of Open Type Rotary Screen Printer is not accurate.
There are many reasons for this situation, which need to be carefully checked, such as whether the rotary screen has loose head and shedding tendency, whether the scraper gas volume is sufficient, the paste paste is applied to the semi-product, the level of the color slurry in the rotary screen changes, and the flower device And whether it affects the parts of the flower, whether the parts of the flower are wet or not, and whether the piled cloth is smooth or not.
