Description

TECHNICAL FIELD

[0001] The utility model relates to paper product processing technical field, especially a paper tube printing device. BACKGROUND

[0002] Paper tube printing is a processing technology of printing patterns, characters or marks on the surface of paper tube, which is widely used in textile, packaging, construction, home furnishing and other industries. As an important industrial material, the printing on the surface of paper tube not only can improve the appearance aesthetics of products, but also can be used for brand identification, product information transmission and functional marking (such as size, specification, etc.).

The above-mentioned patent mainly includes a third electric push rod, a first electric push rod, a second electric push rod and a bottom plate. Although the first electric push rod is used to drive the push rod to elongate so that the printing block moves downward to contact the surface of the paper tube, thereby realizing the printing treatment on the surface of the paper tube, the operation is simple. The first electric push rod is used to drive the printing block to move downward to contact the sponge pad, thereby realizing the re-coloring of the printing block at the end of the first electric push rod push rod. The second electric push rod is used to drive the printing block connected to the end of the push rod to move downward to contact the surface of the paper tube, thereby realizing continuous printing processing. However, the device sets a printing plate to cover print the pattern on the paper tube. Since the paper tube has a curved surface characteristic, the cover printing method is limited by the size and shape of the printing plate, it is difficult to print a long continuous pattern on the surface of the paper tube, and the applicability is poor. If the printing plate is set to an arc-shaped structure matching the paper tube to improve the adhesion, the length of the arc-shaped printing plate is increased, and the contact area between the arc-shaped printing plate and the flat printing box may be suspended in the middle due to the height, so that the ink cannot be uniformly attached to the surface of the printing plate when dipping, thereby easily causing local ink leakage, affecting the integrity and clarity of the pattern transfer.
