Abstract
The invention discloses a single-piece paper double-side printing machine, which comprises an upper embossing roller, a lower embossing roller, an upper rubber roller and a lower rubber roller. The upper rubber roller is arranged between an upper printing plate roller and the upper embossing roller. The upper rubber roller is respectively matched with the upper printing plate roller and the upper embossing roller. The lower rubber roller is arranged between a lower printing plate roller and the lower embossing roller. The lower rubber roller is respectively matched with the lower printing plate roller and the lower embossing roller. The upper embossing roller and the lower embossing roller are covered by stainless steel plates. A gap for passing paper is kept between the upper embossing roller and the lower embossing roller. The single-piece paper double-side printing machine has the advantages that since the paper is printed between the rubber rollers and the embossing rollers, the embossing rollers are covered by the stainless steel plates coated with ceramic coating layers capable of preventing from sticking ink and the texture is rigid, the dots of presswork are clear, the reducibility is good, the paper is not apt to be deformed and the defect of ink ghosting which is apt to occur by using soft-to-soft and rolling-type double-side printing machines is thoroughly eliminated.
Description
Technical field
The present invention relates to a kind of printing machine, particularly relate to a kind of sheet-fed perfecting press.
Background technology
The two-sided printed matter that all need print of paper, usual way is twice printing, after one side is accomplished printing, paper is turned over a body, carries out the printing of another side then.Also having a kind of method is to use perfecting press, and paper once gets into machine, accomplishes double-edged printing; As shown in Figure 1, a colour cell of this perfecting press comprises two plate cylinders 1, two impression cylinders 2 up and down up and down; Coat blanket 3 on the impression cylinder 2; Picture and text printing ink on two plate cylinders 1 is up and down transferred on the blanket 3 of two impression cylinders 2 up and down separately, when paper 4 through up and down between two impression cylinders 2 time; Accomplish a double-edged color printing simultaneously; Usually chromatograp needs 2～4 colors, and then a perfecting press can comprise 2～4 identical colour cells, to accomplish the printing of tow sides 2～4 looks.
Such perfecting press because two impression cylinder 2 surfaces all coat blanket 3 up and down, paper is process between these two cylinders, be blanket and blanket to pressing, so be commonly called as " soft pressure is soft to roller ".Such machine is efficient, simplify, arrogate to oneself especially printed matters such as literal and chart owing to be " soft pressure is soft " form, congenital structures shape the sharpness of dots of its printed matter, reproducibility, all there is deficiency in Deformation of Paper property, and is prone to produce the flaw of printing ink ghost image.
Summary of the invention
The present invention has overcome the deficiency that exists in the above-mentioned prior art; Provide a kind of and made that the printed matter site is clear, Well-recovered, paper is not yielding, and can thoroughly eliminate the new type printing press of the printing ink ghost image flaw that " soft pressure is soft to roller " type perfecting press is prone to produce.
Technical scheme of the present invention is achieved in that
A kind of sheet-fed perfecting press; Comprise upper and lower plate cylinder; Upper and lower impression cylinder and upper and lower blanket cylinder, last blanket cylinder are arranged between plate cylinder and the last impression cylinder, and last blanket cylinder matches with last plate cylinder, last impression cylinder respectively; Following blanket cylinder is arranged on down between plate cylinder and the following impression cylinder; And following blanket cylinder matches with following plate cylinder, following impression cylinder respectively; On upper and lower impression cylinder, all be coated with the stainless steel metal plate, and leave paper supply between last impression cylinder and the following impression cylinder and open the gap of passing through.
After preventing back face printing, the fresh printing ink of the not bone dry on the paper is stained with the dirty impression cylinder of going up, and as preferably, on described stainless steel metal plate, scribbles antiseized black ceramic coating.
Adopted the principle of the present invention and the beneficial effect of technique scheme to be:
One group of colour cell of perfecting press of the present invention comprises up and down two plate cylinders, two blanket cylinders, two impression cylinders up and down up and down; Paper is process between following blanket cylinder and following impression cylinder earlier, accomplishes a back face printing of paper, and paper gets into and goes up between impression cylinder and the last blanket cylinder then, accomplishes the once front printing of paper; Keep a kind of suitable spacing of opening greater than ground paper between last impression cylinder and the following impression cylinder, when guaranteeing that printing is carried out, paper is not squeezed in this position.
Novel two-sided printing machine of the present invention can be made 1 and can be connected by transfer roller between the colour cell until colour cell about in the of 5 by the demand of printed matter print color, can this type of be pushed into 5 colour cells.
Novel two-sided printing machine of the present invention; Paper prints between blanket cylinder and impression cylinder; Impression cylinder coats and scribbles the anti-corrosion resistant plate of being stained with the ceramic coating of printing ink; Its quality is hard, makes that the printed matter site is clear, Well-recovered, paper is not yielding, and thoroughly eliminates the flaw that " soft pressure is soft " " to roller " type perfecting press is prone to the printing ink ghost image of generation.
Description of drawings
Fig. 1 is the structural representation of a colour cell of printing machine in the prior art;
Fig. 2 is the structural representation of a colour cell of printing machine of the present invention.
The specific embodiment
The specific embodiment of the present invention is following:
Embodiment: a kind of sheet-fed perfecting press; As shown in Figure 2; Comprise upper and lower plate cylinder 1,2; Upper and lower impression cylinder 3,4 and upper and lower blanket cylinder 5,6, last blanket cylinder 5 is arranged between plate cylinder 1 and the last impression cylinder 3, and go up blanket cylinder 5 respectively with last plate cylinder 1, go up impression cylinder 3 and match; Following blanket cylinder 6 is arranged on down between plate cylinder 2 and the following impression cylinder 4; And following blanket cylinder 6 is respectively with following plate cylinder 2, impression cylinder 4 matches down; On upper and lower impression cylinder 3,4, all be coated with stainless steel metal plate 7, and leave paper supply between last impression cylinder 3 and the following impression cylinder 4 and open the gap of passing through.On described stainless steel metal plate 7, scribble antiseized black ceramic coating.
Paper is process between following blanket cylinder 6 and following impression cylinder 4 earlier, accomplishes a back face printing of paper; Paper gets into and goes up between impression cylinder 3 and the last blanket cylinder 5 then, accomplishes the once positive printing of paper.
Claims (2)
1. sheet-fed perfecting press; It is characterized in that: comprise upper and lower plate cylinder; Upper and lower impression cylinder and upper and lower blanket cylinder, last blanket cylinder are arranged between plate cylinder and the last impression cylinder, and last blanket cylinder matches with last plate cylinder, last impression cylinder respectively; Following blanket cylinder is arranged on down between plate cylinder and the following impression cylinder; And following blanket cylinder matches with following plate cylinder, following impression cylinder respectively; On upper and lower impression cylinder, all be coated with the stainless steel metal plate, and leave paper supply between last impression cylinder and the following impression cylinder and open the gap of passing through.
