The Open Type Rotary Screen Printing Machine is the key equipment of the printing and dyeing factory and one of the important equipment for the coordination and unification of machinery and electric. The rotary screen printing machine is the equipment responsible for printing as its name suggests, and the printing precision is particularly important. However, there are many factors affecting the accuracy of rotary screen printing. As you know, the current rotary screen printing machine is a high combination of machinery and electric. The analysis of printing accuracy factors cannot be simply divided according to machinery and electric. Instead, the rotary screen printing should be considered as a system.
This paper analyzes the factors of printing accuracy as follows:
1.comprehensive precision of printing system
As is known to us, the printing precision of the traditional mechanical transmission printing machine is mainly ensured by good mechanical cooperation. The traditional mechanical transmission printing machine has to achieve the synchronization of the circular net and the conduction belt. That is to say, the running speed of the rotary net and nickel net, regardless of the steady or variable speed of the conduction belt, strictly controlled within the range of -0.2% to -3%, that is, the speed difference between the circular net and the conduction belt is generally stable. Therefore, we must consider the factors of belt speed, such as the main motor pulley, the transition shaft pulley, the worm gear reducer, the main roller diameter, the guide belt or the fabric thickness; at the same time, it is necessary to consider the gap between the rotary screen and the guide belt, the speed ratio of the net head and the head drive gear, and the speed ratio of the head drive gearbox.
2. Human factors in the printing system
Of course, the human factor in the system is the most important. Different people do the same thing with different results. Designers’ understanding of the Flat Screen Printing Machine , the skill level of the installers, the practical experience, the proper arrangement of the process, the working attitude of the operators, the understanding of the equipment, the responsibility of the maintenance personnel can affect the accuracy of the printing.
