Abstract
The invention relates to a printing cylinder, particular to a printing cylinder of a drum offset printer. A blanket cylinder and an impression cylinder are arranged in the drum offset printer; the printing cylinder and the blanket cylinder are mutually contacted; printing papers are arranged between the blanket cylinder and the impression cylinder; the impression cylinder comprises a bottom cylinder, two brackets and an assembling block; two ends of the bottom cylinder are respectively provided with a bracket; and the assembling block is distributed between the two brackets. In the invention, the intermittent printing of the printer is realized by the unique structure of the printing cylinder; the intermittent printing can greatly broaden the application range of the prior printer, improve the utilization rate of papers and the production efficiency, and reduce the cost.
Description
Technical field
The present invention relates to a kind of printing cylinder, relate in particular to a kind of printing cylinder of roller drum offset machine.
Background technology
Nearly all offset press all is continuous printing sheets at present, because the size of printing press plate cylinder is fixed, is changeless with regard to the breadth that requires to print like this.In case the breadth of paper changes, will occur to print or wasting phenomenon.But in actual life, the breadth of paper is changeable; In present actual print process, the size of forme is owing to the restriction of mode of printing receives certain restriction, so actual at present plate size is a standard; As as far as start, two formes are installed on the plate cylinder, blanket cylinder rolls a circle; Plate cylinder rolls two circles, thereby all is delivered to the printed words of two formes on the plate cylinder on the blanket cylinder, then; Through the paper between impression cylinder and the blanket cylinder, the printed words on the blanket cylinder are delivered on the paper the most at last, accomplish whole printing process.Bring very big inconvenience for so first actual the use because, in case size and the different words of forme standard size that will print, just can't print, otherwise will cause a large amount of wastes of paper; Brought certain restriction second also for the use of printing machine.
Summary of the invention
The bright roll type offset press gap offset printing method that provides, it is unfixing to have solved above-mentioned printed article book size, causes the problem of paper waste.
The present invention is through following technical scheme technical solution problem:
Blanket cylinder, impression cylinder are installed in a kind of printing cylinder of roller drum offset machine, roll type offset press; Be in contact with one another between described plate cylinder and the blanket cylinder, arrange seal paper between blanket cylinder and the impression cylinder; It is characterized in that: described plate cylinder comprises end tube, support, and the assembly unit piece, support is respectively arranged at the two ends of tube of the described end, the assembly unit piece is arranged between the two stands; Also comprise chute, groove; Put up annular for said, and a side of tube is arranged the chute of annular the end of towards, support is arranged several grooves perpendicular to the annular groove direction.
The printing cylinder of roller drum offset machine of the present invention also comprises fixed block, abaculus; Said fixed block is fixed in the groove, and abaculus is arranged between two chutes.
The printing cylinder of roller drum offset machine of the present invention, described groove is a dovetail groove.
Beneficial effect
The present invention can realize the fine batch (-type) printing of offset press through the unique texture of printing cylinder, and the scope of application of current printing machine can be greatly widened in the batch (-type) printing, improve paper utilization rate, enhance productivity, reduce cost.
Description of drawings
Fig. 1 is a printing cylinder structural representation of the present invention;
Fig. 2 is a barrel structure sketch map at the bottom of the printing of the present invention;
Fig. 3 is print principle figure at intermittence of the present invention;
1 is end tube among the figure, the 2nd, and support, the 3rd, assembly unit piece, the 4th, chute, the 5th, groove, the 6th, fixed block, the 7th, abaculus.
The specific embodiment
Below in conjunction with accompanying drawing to further explain of the present invention:
Shown in Figure 1: that blanket cylinder, impression cylinder are installed in a kind of printing cylinder of roller drum offset machine, roll type offset press; Be in contact with one another between described plate cylinder and the blanket cylinder, arrange seal paper between blanket cylinder and the impression cylinder.
Plate cylinder comprises end tube 1, support 2, and assembly unit piece 3, chute 4, groove 5, fixed block 6, abaculus 7,
Fixed block 6 is fixed in the groove 5, and abaculus 7 is arranged between two chutes 4.Groove 5 is dovetail grooves.
As shown in Figure 2: offset press is generally by three cylinder composition-plate cylinders, blanket cylinder and impression cylinders, and by means of the elasticity of rubber, when blanket cylinder rotated, it can make plate cylinder and impression cylinder rotate together.In printing process, forme various to be printed is installed on the plate cylinder, and paper then passes through between blanket cylinder and impression cylinder, and through rolling mutually each other between the cylinder, the various printed words that need print the most at last print on the impression cylinder.
Therefore in the offset press of this patent, be provided with a series of assembly unit pieces, the size of these assembly unit pieces is made according to the plate size that possibly occur in the actual print process, and the size of every assembly unit piece is different, and every printing machine all is furnished with a cover assembly unit piece.They can be according to the concrete size assembly unit freely of treating forme with mobile.The fixed piece of carving refers to motionless inserting, and is mainly used in an end of fixing printing block; Portable abaculus then is to insert along what circumference moved, and it is used for fixing the other end of forme.The mounting blocks that other are inserted and then represent size to differ, they all can move along circumference.
Through such setting; In concrete printing process, the position of packaged type mounting blocks can be adjusted according to concrete print request, and the paper feed of paper is also done corresponding adjustment according to the requirement of plate cylinder with pausing; As antiquarian to be printed has only 1/3rd of plate cylinder; Then as long as adjust the position that forme is installed on the plate cylinder, it is just passable that three formes are installed on a plate cylinder, can not cause the waste of paper; No matter and for blanket cylinder, when no character segment passed through blanket cylinder, it is just passable that paper does not pass through with blanket cylinder, finally accomplishes can both print to great plate size.Thereby improved the utilization rate of paper, widened the scope of application of printing machine.The principle of the clearance-type printing that this patent carries that Here it is.
Claims (3)
