Printing process and printing principle of PVC profile printing machine

- May 12, 2019-

The PVC profile printing machine adopts the principle of electro-engraving gravure printing. It can directly contact the workpiece through the flower plate or transfer the pattern through the rubber wheel. To a certain extent, it can simultaneously print or glaze the special-shaped multi-faceted product at the same time. Wood-based metal, PVC and other surface printed with pattern or full glazing, used for skirting, door line, plastic steel window and other products.

The pattern of PVC profile printing machine can be made according to the customer's drawings. The approximation degree is 98.8%. The frequency conversion speed regulation can be adjusted to 0-30 m/min. Printing paint (ink) can be recycled through the oil tank.

During the printing process of the PVC profile printing machine, the screen printing plate and the squeegee plate are moved relative to each other, and the pressing force F1 and the resilience force F2 are also synchronously moved. Under the action of the resilience force, the screen is detached from the substrate in time. Contact to avoid smudging the print. That is, the screen is constantly in the process of deformation and rebound during the printing process.

After the squeegee finishes unidirectional printing, it is separated from the substrate together with the screen printing plate, and at the same time, returning ink is returned, that is, a printing cycle is completed. The distance between the top of the substrate and the opposite side of the screen printing plate after ink return is called the same plate spacing or mesh distance, and should generally be 2 to 5 mm. When hand-printed, the manipulation and proficiency of the operator directly affects the formation of the embossed
