Abstract
The utility model provides a double diameter cylinder sheet-fed offset perfector. The double diameter cylinder sheet-fed offset perfector comprises an upper plate cylinder, a lower plate cylinder, an upper blanket cylinder which is in transmission connection with the upper plate cylinder, a lower blanket cylinder which is in transmission connection with the lower plate cylinder, an upper impression cylinder which is in transmission connection with the upper blanket cylinder and a lower impression cylinder which is in transmission connection with the lower blanket cylinder; the transmission connection between the upper impression cylinder and the lower impression cylinder is that the upper and lower impression cylinders are staggered up and down; the diameters of the upper and lower impression cylinders are double the diameters of the conventional upper and lower impression cylinders. When the double diameter cylinder sheet-fed offset perfector is used for printing, the double diameter cylinder sheet-fed offset perfector can effectively solve the problems that the sharpness of dots and reducibility of presswork are insufficient, paper is easily deformed and ink doubling is easily generated in the first type of perfector in the prior art, and also radically solves the problem that stripping roller marks are easily generated on presswork in the second type of perfector.
Description
Technical field
The utility model relates to printing technology, relates in particular to a kind of two-around cylinder sheet-fed offset perfector.
Background technology
The two-sided printed matter that all needs printing of paper, usual way is twice printing, on single-side machine, completes after one side printing, manually paper is turned over to a body, then carries out the printing of another side.Also having a kind of method is that paper once enters machine, completes double-edged printing with perfecting press.
Existing perfecting press mainly contains two kinds of forms:
Fig. 1 is the first perfecting press structural representation in prior art; As shown in Figure 1, a colour cell of the first perfecting press comprises upper and lower two plate cylinders, upper and lower two impression cylinders, coated blanket on impression cylinder, picture and text ink on upper and lower plate cylinder, transfer to separately on the blanket of upper and lower two impression cylinders, in the time that paper passes through between upper and lower two impression cylinders, complete double-edged each color printing simultaneously, conventionally chromatograp needs 2-4 color, a perfecting press can comprise 2-4 identical colour cell, to complete the printing of tow sides 2-4 look.
Fig. 2 is the second perfecting press structural representation in prior art; As shown in Figure 2, the second form perfecting press colour cell comprises upper and lower two plate cylinders, upper and lower two blanket cylinders, upper and lower two impression cylinders.Paper is process between lower blanket cylinder and lower impression cylinder first, completes a back face printing of paper.Then paper enters between impression cylinder and upper blanket cylinder, completes the once positive printing of paper.Between upper impression cylinder and lower impression cylinder, keep a kind of suitable spacing that ground paper is opened that is greater than, when ensureing that printing is carried out, paper is not squeezed in this position.
The perfecting press of the first form because all coated blankets of upper and lower two impression cylinder surfaces, paper is process between these two cylinders, be blanket and blanket to pressure, so be commonly called as " soft pressure is soft ".Such machine is efficient, simplify, especially arrogate to oneself the printed matters such as graphics, owing to being " soft pressure is soft " form, congenital structures shape the sharpness of dots of its printed matter, reproducibility Shortcomings, and easily produce paper distortion, the flaw of printed matter ink ghost image.
The perfecting press of the second form, paper prints (being commonly called as soft pressure hard) between blanket cylinder and impression cylinder, the coated ceramic coating corrosion resistant plate of preventing being stained with ink that scribbles in impression cylinder surface, its quality is hard, make that printed matter site is clear, Well-recovered, paper is not yielding, and thoroughly eliminate the flaw of the ink ghost image that the first form perfecting press easily produces.But also due to congenital structures shape paper printed not yet completely by the rigid impression cylinder of peeling off, thereby produce the black thick stick of peeling off on printed matter.
Utility model content
The purpose of this utility model is to solve the defect that above-mentioned prior art exists, and a kind of novel two-around cylinder sheet-fed offset perfector is provided.
A kind of two-around cylinder sheet-fed offset perfector, comprise plate cylinder, lower plate cylinder, with the upper blanket cylinder of upper plate cylinder driving coupling, with the lower blanket cylinder of lower plate cylinder driving coupling, with the upper impression cylinder of upper blanket cylinder driving coupling, with the lower impression cylinder of lower blanket cylinder driving coupling, the driving coupling of described upper impression cylinder, lower impression cylinder is for shifting to install up and down, and the diameter of upper impression cylinder, lower impression cylinder is the twice of existing diameter.
Further, two-around cylinder sheet-fed offset perfector as above, also comprise the first transfer roller, the second transfer roller, described the first transfer roller connects setting with lower impression drum drive, the upper impression cylinder driving coupling of the second transfer roller and an other colour cell offset press arranges, the horizontal driving coupling setting of described the first transfer roller and the second transfer roller.
Further, two-around cylinder sheet-fed offset perfector as above, also comprise the first transfer roller, the second transfer roller, described the first transfer roller and upper impression cylinder driving coupling arrange, the second transfer roller connects setting, the horizontal driving coupling setting of described the first transfer roller and the second transfer roller with the lower impression drum drive of other one group of offset press of look.
The two-around cylinder sheet-fed offset perfector that the utility model provides, among each print couple unit, has adopted two times of footpath impression cylinders of prior art to hocket and has printed the frame mode of action.While carrying out printing work, can effectively solve the flaw that existing the first form perfecting press printed matter sharpness of dots and reproducibility deficiency, paper are yielding, easily produce ink ghost image; The utility model two-around cylinder sheet-fed perfecting press has also solved the black thick stick of peeling off on the easy printed matter producing of the second form perfecting press completely.
