Abstract
The invention discloses an offset printing press with an excellent printing effect. The offset printing press comprises a plate cylinder, a blanket cylinder and an impression cylinder, wherein the plate cylinder is matched with the blanket cylinder; the blanket cylinder is matched with the impression cylinder; a blowing pipe is arranged beside the blanket cylinder and is also arranged at the one fourth circumferential position of the blanket cylinder which rotates to pass through a tangential point of the blanket cylinder and the impression cylinder; a hot air source is connected to the blowing pipe; the blowing pipe is arranged in the axial direction of the blanket cylinder; and a plurality of through holes are distributed in the wall of the blowing pipe in the axial direction. According to the offset printing press disclosed by the invention, the blowing pipe is mounted at the position close to the blanket cylinder; after the blanket cylinder rotates to pass through the tangential point of the blanket cylinder and the impression cylinder, the blowing pipe blows uniformly hot air and can be used for blowing a foundation solution with high water content resided on the blanket cylinder to be uniform and volatizes consistent part of water content. Therefore, water transferred to paper of the printing cylinder is reduced, the deformation of the paper is really reduced and the quality of printed matters is improved.
Description
Technical field
The present invention relates to a kind of offset press, particularly a kind of offset press with good printing effect.
Background technology
Offset press comprises plate cylinder, blanket cylinder, impression cylinder.The inking system of offset press, water-carriage system are supplied with printing ink and fountain solution on the forme of plate cylinder; Utilize the immiscible principle of profit; Picture and text on the forme partly are ink-receptive, only accept the printing ink of ink feeding system: and blank parts is hydrophilic, only accepts fountain solution; Plate cylinder is with the picture and text of having accepted printing ink and fountain solution on the forme; Transfer on the blanket cylinder, picture and text printing ink that blanket cylinder shifts forme again and fountain solution are printed onto impression cylinder and grit one's teeth on the paper of biting, and promptly accomplish the printing of a color.Picture and text printing ink and forme liquid are from plate cylinder → blanket cylinder → paper, and through secondary transferring, printing ink and fountain solution are all transferred on the paper; Printing process is to have accomplished, but last unwanted fountain solution also transfers on the paper, and this fountain solution contains large quantity of moisture; And skewness, paper have absorbed these uneven moisture, can cause distortion; And produce printing net-point distortion, printing overprint error, influenced the quality of printed matter.
Summary of the invention
The present invention has overcome the technical problem that exists in the above-mentioned prior art, and a kind of offset press that can effectively reduce paper distortion, improve printing quality is provided.
Technical scheme of the present invention is achieved in that
A kind of offset press with good printing effect; Comprise plate cylinder, blanket cylinder and impression cylinder, described plate cylinder matches with blanket cylinder; Blanket cylinder matches with impression cylinder; Be provided with blower in that blanket cylinder is other, and blower is arranged on the quadrant position at the point of contact that turns over blanket cylinder and plate cylinder of blanket cylinder, described blower is connected with hot air source; Blower is along the setting of blanket cylinder axial direction, on the blower tube wall, is provided with a plurality of through holes that distribute vertically.
As preferably, the through hole on the blower be shaped as rectangle.The through hole of rectangle forms a word air outlet, reaches the effect of " air knife ", has improved the blowing ability.
As preferably, described blower is made up of two hollow pipes.
Adopted the invention has the beneficial effects as follows of technique scheme:
The present invention has installed blower in the position near blanket cylinder; After blanket cylinder rotates through the point of contact with plate cylinder; Blower blows out uniform hot blast, and can the fountain solution that has large quantity of moisture remaining on the blanket cylinder be blown and comfort evenly, and the moisture of volatilization considerable part.Made it to reduce on the paper of water transport to the printing cylinder, reduced Deformation of Paper effectively, also reduced printing net-point distortion, overprint error, improved the quality of printed matter.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of blower.
The specific embodiment
The specific embodiment of the present invention is following:
Embodiment: a kind of offset press with good printing effect, as shown in Figure 1, comprise plate cylinder 7; Blanket cylinder 6 and impression cylinder 9, described plate cylinder 7 matches with blanket cylinder 6, and blanket cylinder 6 matches with impression cylinder 9; At the blanket cylinder 6 other blowers 4 that are provided with; Blower 4 that the position is set is also important, through experiments, blower 4 is arranged on the quadrant position that turns over blanket cylinder 6 and the point of contact 8 of plate cylinder 7 of blanket cylinder 6; Described blower 4 is made up of two side-by-side hollow pipes; Described blower 4 is connected with the hot air source (not shown), and blower 4 is along blanket cylinder 6 axial direction settings, on blower 4 tube walls, is provided with a plurality of through holes 5 that distribute vertically.
As shown in Figure 2, the through hole 5 on the blower 4 be shaped as rectangle.The through hole of rectangle forms a word air outlet, reaches the effect of " air knife ", has improved wind-force.
