Abstract
The utility model provides a hard-pressing soft sheet-fed double-surface double-color offset printer, and is composed of rigid impression cylinders E, A, a rubber blanket cylinder B, a plate cylinder P, paper-transferring cylinders G, D, S and a collecting cylinder F which are all supported on a base. The hard-pressing soft sheet-fed double-surface double-color offset printer comprises four printing units, a printing unit I and a printing unit II are formed by sequentially arranging the rigid impression cylinder E, the blanket cylinder B and the plate cylinder P from up to down, a printing unit III and a printing unit IV are formed by sequentially arranging the impression cylinder A, the rubber blanket cylinder B and the plate cylinder P from up to down, further, the paper-transferring cylinder utilizes a double-diameter cylinder of the rubber blanket cylinder which can efficiently reduce the bending deflection of papers, simultaneously reduces connecting times of papers, and is favorable for sleeving wires. The cylinders which utilize the structure to realize sharing one gripper edge, avoiding turning over, achieving hard-pressing soft print, and meet requirements of high-quality printing.
Description
Technical field
The utility model relates to a kind of offset press, is specifically related to the soft sheet-fed dual-sided two color of a kind of hard pressure offset press.
Background technology
Relevant by retrieval patent documentation does not retrieve the dual-sided two color offset press identical with the utility model structure at present, and only retrieving the patent No. is 200520074414.5, and patent name is a Perfector for hard press soft single paper.Along with the development of print utility, the quality requirement of book and periodical printing is also improving greatly, and not only the definition to font has improved requirement, to the also raising greatly of requirement of written color, no longer is satisfied with single color.In order to address this problem, some placards, advertising and printing and books and periodicals mostly adopt the import printing machine.And the machinery of foreign country is because structure is very complicated, paper is required high, also high to operating personnel's specification requirement, this mode of the general incompatibility of native paper is printed, so extremely be difficult to promote, and the machine cost is very expensive, even the strong producer of minority is afforded, also is difficult to bear the expense of paper during use.So be necessary existing offset press is improved, to satisfy demand of practical production.
The utility model content
The utility model provides the soft sheet-fed dual-sided two color of a kind of hard pressure offset press, form by support upper support rigidity impression cylinder E, A, blanket cylinder B, plate cylinder P, transfer roller G, D, C and collecting cylinder F, preceding transfer roller G reaches paper in the transfer roller D, it is characterized in that: the soft sheet-fed dual-sided two color of described hard pressure offset press has four printing elements, and printing element I, II are rearranged by rigidity impression cylinder E, blanket cylinder B, plate cylinder P respectively successively from top to bottom; Printing element III, IV are rearranged by impression cylinder A, blanket cylinder B, plate cylinder P respectively successively from top to bottom; Between described printing element I and II, connect with transfer roller D respectively; Also be to connect between described printing element III and IV with transfer roller D; Between printing element II and III, connect with transfer roller D, C, four transfer rollers of D, D successively.
Transfer roller G, blanket cylinder B are identical with plate cylinder P size before described.
Described transfer roller D, rigidity impression cylinder E, A, collecting cylinder F are the twice footpath of blanket cylinder B.
Described transfer roller C is three times of footpaths of blanket cylinder B.
Have anti-set-off sheath on the described impression cylinder A.
The advantage of above structure is: described transfer roller adopts the diameter cylinder of blanket cylinder, can reduce the flexural deformation of paper effectively, simultaneously, reduces the handing-over number of times of paper, helps overlapping line; Described cylinder adopts the arrangement of this structure, realizes a shared leading edge, does not overturn, and presses soft printing firmly, satisfies high-quality printing demand.
Description of drawings
Figure is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, paper feeding parts 1 link to each other with rack unit 2, and institute's seal paper is sent on the preceding transfer drum G3.Transfer roller G3 and printing element I4, II5, III6, IV7 and transfer roller C8, D9, rigidity impression cylinder E10, blanket cylinder B11, plate cylinder P12 collecting cylinder F13 all are bearing on the rack unit 2 before described.Printing element I4, II5 are rearranged by rigidity impression cylinder E10, blanket cylinder B11, plate cylinder P12 respectively successively from top to bottom; Printing element III6, IV7 are rearranged by impression cylinder A14, blanket cylinder B11, plate cylinder P12 respectively successively from top to bottom.Described rigidity impression cylinder E10, A14 are the twice footpaths of blanket cylinder B11, plate cylinder P12, and be identical with the doubly footpath of transfer roller D9, collecting cylinder F13; The doubly footpath of blanket cylinder B11, plate cylinder P12 and preceding transfer roller is identical.Connect with transfer roller D9 respectively between printing element I4 and the II5; Also be to connect between described printing element III6 and IV7 with transfer roller D9; Connect with transfer roller D9, C8, four transfer rollers of D9, D9 successively between printing element II5 and III6, the doubly footpath of described transfer roller C8 is three times of footpaths of blanket cylinder B11.
Paper is passed to transfer roller D9 by preceding transfer roller G3, transfer roller D9 delivers to printing element I4 with the reverse side of paper, rigidity impression cylinder E10 by printing element I4, with the impression of blanket cylinder B11, all picture and text of first kind of color of reverse side of paper are imprinted on the paper, and the color of color has plate cylinder P12 to provide; After this program finishes, by transfer roller D9 paper is passed to printing element II5, printing element II5 is impressed into the color that the plate cylinder P12 of this unit is provided on the reverse side of paper by same path.
After the picture and text impression of reverse side of paper finishes, pass to the transfer roller C8 in three times of footpaths by the transfer roller D9 in twice footpath, transfer roller C8 passes to impression cylinder A14 by two transfer roller D9 again, be with anti-set-off porcelain sheath on the impression cylinder A14, impress the picture and text in paper front jointly with blanket cylinder B11, the course of work of printing element III6 and printing element IV7 is identical with the course of work of the printing I4 of unit, II5, no longer repeats at this.Paper is sent paper collecting mechanism 15 to by collecting cylinder F13 after going out from the impression cylinder A14 of printing element 4.
