Web-fed material printing equipment with adjustable width of plate with shaft

Abstract

The invention relates to the technical field of printing equipment, and particularly relates to web-fed material printing equipment with the adjustable width of a plate with a shaft. The equipment comprises a printing rack, the printing rack comprises a bottom plate, vertical plates are fixed on two sides of the top surface of the bottom plate, the middle part of one vertical plate is rotatably connected with a driven ejector shaft, the middle part of the other vertical plate is provided with a square hole, a main transverse rod and an auxiliary transverse rod are fixed between the upper portions of the inner side walls of the two vertical plates, conveying rollers are rotatably connected to the positions, located on the lower portion of the main transverse rod, of the inner side walls ofthe two vertical plates, and an ink fountain fixing mechanism used for bearing an ink fountain is arranged on the top face of the bottom plate. According to the web-fed material printing equipment, after a first nut block moves relatively, a driving rod can be driven to push an ejector shaft fixing frame to move along a sliding rail, and compared with the mode that the driven ejector shaft is changed to fix plate cylinders, the structure is higher in plate cylinder rotating stability, therefore, the fixing firmness of the printing equipment on the plate cylinders with different plate widths isimproved, and the investment cost of the equipment of enterprises is reduced.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a roll material printing equipment with adjustable tape shaft plate width. Background technique [0002] Web printing equipment is a machine that uses gravure printing. The graphic part of the printing plate is concave, and the blank part is on the same plane as the outer circle of the printing plate cylinder. When the roll material printing equipment prints, the entire plate cylinder is inked, and the ink on the blank part of the plate is scraped off with a scraper, leaving the ink on the graphic part, and then passed through the paper, and the impression cylinder is pressed on the back of the paper. Printing, so that the ink in the concave part is directly transferred to the paper surface, and finally the printed matter is piled up or rewound through the receiving part. [0003] When the roll material is printed, the corresponding wide-width version roller is usual...

Problems solved by technology

[0003] When the roll material is printed, the corresponding wide-width version roller is usually selected according to the width of the printing object, and these different-width version rollers will be combined with the printing equipment corresponding to the wide-width movable model, and a single model supports The width of the tape shaft plate is limited, and the length range of the tape shaft plate width is too large, which affects the stability of the plate roll rotation and the printing quality of the product. Therefore, for enterprises, the investment cost of printing equipment with multiple ranges of tape shaft plate width is high. At the same time, the existing When the roll material printing equipment installs the ink tank, it is usually installed by manual handling. However, due to the influence of the structure of the printing frame, when the operator carries it, the body is mostly in a twisted state, which is not convenient for the operator to apply force. , affect the loading and unloading efficiency of the ink tank, and even cause the ink tank to leak, affecting the normal operation of the printing equipment
