Embodiment Construction

[0026] In the traditional horizontal guide belt printing equipment, there is usually a roller shaft under the plate roller assembly for printing, and the roller shaft and the printing plate roller or transfer roller press the guide belt and the printing material between the two , especially in the wide-format printing process, in order to achieve a stable printing effect, a certain pressure is usually applied between the roller shaft and the printing plate roller or transfer roller through the cylinder. During the printing process, the guide belt needs to withstand the printing The moving horizontal pulling force also bears the vertical pulling force, especially between two adjacent plate printing components, it is easy to appear U-shaped depression or skewed deformation and distortion, which will seriously affect the quality of color printing. This situation is also very complicated and troublesome, the maintenance and debugging of the equipment are relatively difficult, and t...

Abstract

The invention discloses a chain plate guiding belt type version roller printing mechanism and belongs to the technical field of version roller printing. The chain plate guiding belt type version roller printing mechanism comprises horizontally-arranged guiding belts and guiding belt roller shafts supporting the guiding belts. A motor is arranged at one end of one guiding belt roller shaft. The upper surface of an upper-layer guiding belt is configured and used to bear a printed material. Multiple version roller assemblies are arranged above the upper-layer guiding belt. The version roller assemblies are configured and used to conduct polychrome printing operation on the printed material. A gyration chain plate mechanism is arranged below the upper-layer guiding belt. The gyration chain plate mechanism comprises multiple chain plates capable of meshing front and back. The chain plates are connected with chains. The chain plates are connected end to end by the chains, and gyration movement can be conducted by the chains. Chain plate roller shafts are arranged on the inner sides of two ends of the chains. The motor and a gearbox are connected to one end of one chain plate roller shaft. Weight-bearing transverse beams are arranged below the chain plates. The upper surface of the gyration chain plate mechanism is attached tightly to the lower surface of the upper-layer guiding belt.

Description

technical field [0001] The invention belongs to the technical field of version roller printing, in particular to a chain plate guide belt type version roller printing mechanism. Background technique [0002] During the printing process of the plate roller gravure printing machine, the auxiliary patterns to be printed are decomposed into simple patterns such as dry and engraved on the printing plate rollers. When printing, the printing materials pass through the printing units in sequence through the feeding part. The printing unit prints the corresponding pattern on the printing material, and finally obtains the auxiliary printed pattern. In the printing process, there is a problem of accurate positioning of the corresponding printing pattern of each unit, that is, the problem of color registration error, and the accuracy of color registration is very important to the impact of product quality. [0003] In view of the impact of color registration accuracy on product quality...
