Dual-arm and dual-shaft crossed type pillow iron structure of flexo printing machine

Abstract

The invention relates to a dual-arm and dual-shaft crossed type pillow iron structure of a flexo printing machine. The dual-arm and dual-shaft crossed type pillow iron structure comprises an anilox roller, a forme roller and an impression roller, wherein shoulder irons are coaxially arranged on forme shafts on the outer sides of the two ends of the forme roller in a sleeving manner; impression roller pillow irons and anilox roller pillow irons are arranged on the outer sides of the two ends of each of the impression roller and the anilox roller respectively; the shoulder irons are pressed against the impression roller and the anilox roller; the lower parts of the two impression roller pillow irons are arranged on a rotating shaft of the impression roller together in a penetration manner; the lower parts of the two anilox roller pillow irons are arranged on a shaft of the anilox roller together in a penetration manner. The dual-arm and dual-shaft crossed type pillow iron structure is simple in structure, scientific in design and easy to manufacture; compared with the existing design, the novel design has the advantages of higher stability and more convenience in adjustment, and the structure is hardly required to be adjusted by an operator; the overall machine is low in design consumption, high in efficiency and relatively low in cost.

Description

technical field [0001] The invention relates to the field of flexographic printing machines, in particular to a double-arm, double-axis cross-type sleeper structure of a flexographic printing machine. Background technique [0002] The flexographic printing machine is one of the commonly used printing machines. The transmission unit inside the existing flexographic printing machine is mainly composed of anilox roller, printing plate roller and embossing roller. Iron, on the outside of the embossing roller and the anilox roller, the embossing roller sleeper iron and the anilox roller sleeper iron are respectively arranged, the shoulder iron is placed on the embossing roller sleeper iron and the anilox roller sleeper iron, and the paper passes from the printing plate roller and the anilox roller Printing and coloring can be done by passing between the embossing rollers. During the printing process, the printing plate rollers are usually replaced according to the printing needs....

AI Technical Summary

Problems solved by technology

Under the specified thickness of the double-sided adhesive tape, after one adjustment, the replacement of the plate roller does not need to adjust the anilox roller sleeper. Under a specific material thickness (this probability is very small), after one adjustment, it is not necessary to replace the impression roller Adjust the embossing roller sleeper, this design is less adaptable to the thickness of the material, because when the embossing roller sleeper is adjusted, the increment of point D (the point of tangency between the maximum printing plate roller and the embossing roller) is greater than that of point C (minimum The tangent point between the printing plate roller and the embossing roller) increment, when the material is thicker, the printing pressure of the printing plate roller is small, and the printing pressure of the printing plate roller is small; when the material is thin, the printing pressure of the printing plate roller is large, and the printing plate roller Small printing pressure is small, so fine-tuning is required when changing jobs, which also leads to long adjustment time and low adjustment accuracy, which affects the quality of printed matter
