The double-station printing coating machine is mainly used for making tape, reflective film, protective film, coloring, and potion for BOPP, PVC, PET paper and other materials. A-type machine is mainly used for coating BOP P, PVC, PET And paper, materials that will not stretch after being heated, and B-type machine is used for PE and other materials that will stretch after being heated. The double-station printing machine adopts Delta frequency conversion speed controller to control the speed, Delta PLC system uses automatic tension control technology, adopts line roller coating or three-roller reverse metering blade coating, etc., the glue is uniform, and the amount of glue can be To adjust, use electric heating or steam heating drying method.
1 Application Brief
The mechanical structure of the double-station printing and coating machine can be divided into the double-station unwinding part, the printing coating and drying part, the rewinding part, etc .; the transmission points mainly include the unwinding A axis, the unwinding B axis, and the unwinding traction , Printing and coating shaft, sprocket drive shaft, main traction motor, winding shaft, etc.
The working principle of the double station printing and coating machine is to install the paper or PE film to be processed on the unwinding axis A or B axis, and then pretension the unwinding and rewinding rollers and press them against the roller, while pressing the paper direction Pass the paper to start the main motor, make the plate roller and the pressure roller press, and adjust to the appropriate tension to start the machine; adjust the position of the deviation roller to adjust the flatness of the paper; adjust the air pressure of the swing cylinder to control the paper or PE film, etc. The tension of the processed product, the unwinding shaft adjusts the speed of the film through the tension swing rod, and the unwinding traction, coating printing and winding shaft, etc., all run smoothly through the swing rod feedback to adjust the speed of the transmission point, so as to achieve good printing quality and effect. The main technical parameters of the equipment are shown in Table 1 below.
