Abstract
The utility model relates to a total sheet four-color offset press in printing industry, which comprises a paper feed machine, a first color unit, a second color unit, a third color unit, a fourth color unit and a paper collection machine. Five central paper transferring cylinders of the same diameter, which are used for transferring printing paper, are arranged between the second color unit and the third color unit, and the diameter of each central paper transferring cylinder is the same as the diameter of each of plate cylinders and each of impression cylinders, wherein the plate cylinders and the impression cylinders are arranged in the four single color units. The structure of the four single color units is basically the same so that components of the complete machine have good universality. The five central paper transferring cylinders which have the same diameter as the diameter of each plate cylinder and each impression cylinder of the four single color units are used for transferring paper between the second color unit and the third color unit; thereby, the paper transferring cylinders have good universality, and meanwhile, the time interval between second color printing and third color printing is extended, the drying time of ink is extended, the phenomenon of dirty ink is reduced and convenience is offered to the adjustment of the units.
Description
Technical field
The utility model relates to the offset press of printing industry, particularly a kind of four colour offset press.
Background technology
Relevant by retrieval patent documentation does not retrieve a kind of complete the four colour offset press identical with the utility model structure at present as yet.Existing four colour offset press, the general employing adding three transfer rollers or adopting a doubly directly middle transfer roller to realize the transmission of seal paper between two groups of dichromatism units between two groups of dichromatism seal machines, though these class methods obtain certain utilization, but the also reason of arranging owing to roller frame, it is more to add to the printing chromatic number, and seal paper can not get effective dry, makes printing quality fail to obtain optimum efficiency, so be necessary to develop a kind of printing precision, offset press that quality is higher, to adapt to actual demand.
Summary of the invention
The purpose of this utility model is that a kind of improvement on existing four colour offset press will be provided, and it is long to have the printing gap time, and the universal component performance is good, printing quality height, a kind of complete four colour offset press easy to adjust.
Technical characterictic of the present utility model is: consider that universal performance is good, printing is designed to a kind of complete four colour offset press comprising that paper guide, the first look unit, the second look unit, the 3rd look unit, four-color machine group, paper collecting machine are formed clearly on the basis; Five identical middle transfer rollers that are used to transmit seal paper of diameter also are installed between the second look unit, the 3rd look unit.Plate cylinder in the middle of described in diameter and four the monochromatic units of transfer roller, the diameter of impression cylinder are identical.
Add man-hour, connect power supply, paper guide will print paper and pass to the first look unit and print, to print paper again passes to the second look unit and carries out the second look printing, the transmission of transfer rollers in the middle of five will be printed paper again and be passed to the 3rd look and print, and the 3rd look unit will print paper again and pass to the four-color machine group and carry out four-color process, the printing that prints is collected folded through paper collecting mechanism, then obtain required printing.
The utility model has the advantages that:, thereby make the complete machine parts have good versatility because four monochromatic set structures are basic identical; Owing to adopt and four monochromatic unit plate cylinders, five middle transfer rollers that the impression cylinder diameter is identical are as the transmission of paper between second look and the 3rd look unit, thereby not only make transfer roller that good versatility is arranged, make time interval growth between second and third look printing simultaneously, extended the ink setting time, reduced the generation of dirty black phenomenon, and, made the adjustment of unit more convenient because the distance between second and third look unit increases; Because rational in infrastructure, the print quality height is so have very big exploitation and market sale prospect.
Description of drawings
Below with reference to description of drawings embodiment of the present utility model:
Accompanying drawing is the structural representation of a kind of complete four colour offset press of the utility model.
The specific embodiment
With reference to accompanying drawing, the utility model is made up of paper guide 1, the first look unit 2, the second look unit 3, the 3rd look unit 4, four-color machine group 5, paper collecting machine 6, be equipped with also between the second look unit 3, the 3rd look unit 4 that diameter is identical to be used to transmit transfer roller 7a in the middle of five of seal paper, 7b, 7C, 7d, 7e, the plate cylinder in the diameter of middle transfer roller 7 and four the monochromatic units, the diameter of impression cylinder are identical.
Claims (2)
1, a kind of complete four colour offset press, comprise paper guide (1), the first look unit (2), the second look unit (3), the 3rd look unit (4), four-color machine group (5), paper collecting machine (6), it is characterized in that: five identical middle transfer rollers (7) that are used to transmit seal paper of diameter also are installed between the second look unit (3), the 3rd look unit (4).
