Key technology of fabric screen printing
Textile screen printing equipment precision requirements, equipment operating environment is relatively harsh, long working hours, the test of the equipment is harsh.In printing equipment, there are many key technologies to be mastered, such as plate transmission, plate positioning, plate energy-saving drying, plate reversing, plate scraping device, etc.
(1) The positioning technology between platen and screen frame is one of the most important technologies. In screen printing equipment, the positioning accuracy between screen frame and screen plate is very high. The accuracy between the two directly affects the printing quality of cutting pieces and determines the quality level of products.
(2) The energy-saving drying technology of the platform is also very important. In the drying process, basically high-power heating pipes are used to bake in an open space for a short time, so the energy utilization rate is low.
(3) In the transmission link of the platform, there are more of the overall chain drive mode, which is easy to achieve, low cost, but low precision, the positioning of the platform is also affected.
(4) The reversing device and scraping device of the platens affect the quick reversing of the platens on both sides of the equipment and the quick printing of cutting pieces. The reversing device has fast speed and high precision, stable scraping of the printing device and moderate pressure, which can significantly improve the working efficiency of the printing equipment and increase the economic benefits of the manufacturer.
Pneumatic system is a relatively weak link in the screen printing equipment. Due to the poor working environment of the printing machine, the surrounding is full of dust and short fibers, which has a great impact on the pneumatic system.The maintenance, maintenance and repair of pneumatic system are all problems that need to be paid attention to. The pneumatic system of automatic screen printing requires quick response, high positioning accuracy, accurate control and easy operation.
