Description

Technical Field

[0001] The utility model belongs to the technical field of printing equipment, and particularly relates to a rotary printing device.

Background Art

[0002] Printing is a process of transferring ink to the surfaces of materials such as paper, textiles, plastics, leather, PVC, PC, etc. through processes such as plate making, inking, and pressing for originals such as text, pictures, photos, anti-counterfeiting, etc. Currently, more and more products and packaging need to be printed, and printing technology is becoming more and more advanced. When printing a large number of products, a printing production line is usually used to ensure the printing efficiency. The existing printing production line uses a conveyor line to convey the products to be printed. When the products to be printed pass through the printing device, they are first fixed and then printed. After printing, they are directly discharged by the conveyor line. The products to be printed and the printed products are both conveyed on the same conveyor line in the same conveying direction, resulting in a large overall floor area.
