Curved-surface offset printing machine for large basin printing

Abstract

The invention relates to the technical field of large basin printing, in particular to a curved-surface offset printing machine for large basin printing. The curved-surface offset printing machine forlarge basin printing comprises an index plate mounted on an indexer. A driving roller is transversely arranged in a cylinder, one end of the driving roller penetrates through the cylinder to extend to the outside, and the driving roller is rotationally connected with the cylinder. A conveying disc sleeves the driving roller and is connected with the driving roller through a second fixing assemblyand matched with the cylinder. A conveying belt is horizontally arranged on the upper side of the cylinder, the input end of the conveying belt corresponds to an inlet and an outlet in the upper sideof the cylinder in position, and the index plate, the driving roller and the conveying belt are connected through a transmission assembly. An abutting rod is fixedly and vertically connected with thelower side of a movable frame body, an inner curved surface offset printing assembly is arranged on the abutting rod, and the movable frame body is driven by a pneumatic telescopic rod on the upper side of the movable frame body. Offset printing can be carried out on the inner curved surface and the outer curved surface of a large basin, automatic offset printing is achieved through the whole machine, the conveying belt, the conveying disc and the index plate work synchronously, transmission is carried out through the transmission assembly, and errors are avoided.

Description

technical field [0001] The invention relates to the technical field of large basin printing, in particular to a curved offset printing machine used for large basin printing. Background technique [0002] Curved surface offset printing machine is a special printing equipment used to print trademarks, characters and patterns on the surface of containers such as plastic cups, plastic bowls, plastic hoses or plastic barrels. Because the outer surface of this type of plastic container is generally a curved surface, it is called a curved surface offset printing machine. Both screen printing and curved offset printing can be used to print on the surface of plastic containers, but compared with screen printing, curved offset printing uses rubber rollers for pattern transfer, and through the ductility of rubber, the pattern is perfectly printed on the container. , has higher printing convenience, so curved surface offset printing technology has developed rapidly in recent years. ...

AI Technical Summary

Problems solved by technology

[0005] 1. It is not convenient to offset the curved surface inside the large basin;

[0006] 2. Each step of the scheme is independent, and errors are prone to occur in mechanical control, resulting in poor offset printing effect
