Abstract
The invention relates to a full-sheet multi-color register offset press in the printing industry. The full-sheet multi-color register offset press comprises a paper conveying mechanism, a first printing component, a general printing unit, a paper collection mechanism and a rack, wherein the paper conveying mechanism is connected with the rack; the first printing component is arranged on the rack; at least one group of general printing unit is arranged on the rack; the rack is provided with the paper collection mechanism; the diameter of an impression cylinder and a paper delivery cylinder in the general printing unit is double of the diameter of a plate cylinder and a rubber cylinder; and the impression cylinder is provided with a paper occluding tooth opening torsion spring device. As the diameter of the impression cylinder and paper delivery cylinder is double of the diameter of the plate cylinder and rubber cylinder, the curve of the paper is reduced, and the printing precision is improved; multiple groups of general printing units are combined in a superposed mode, and the required color-register offset press can be obtained by superposition according to the need; with the ink oscillation position adjusting mechanism, the position with maximum use of printing ink can be adjusted; and due to the paper occluding tooth opening torsion spring device, the paper occluding pressure can be conveniently adjusted.
Description
Technical field
The present invention relates to a kind of offset press of printing industry, specifically a kind of chromatography offset press more than complete.
Background technology
Through the relevant patent documentation of retrieval, do not retrieve complete the open many chromatography offset press identical at present as yet with structure of the present invention.The offset press structure of domestic existing production is more, differs from one another, and existing many chromatographys offset press is generally only split four colour offset press; And for various reasons, make printing quality be difficult to guarantee, particularly for the large format printing; Because the large format printshop is bigger with the paper breadth; Be prone to distortion after the printing, give back road printing, particularly make precision be difficult to be guaranteed for many chromaticity printings; And because existing many chromatographys offset press structure is comparatively complicated, versatility is bad, when needs carry out the trapping printing increase; Then be difficult to offset press is improved upgrading; So be necessary existing offset press is improved, it is better to reach versatility, improves the purpose of printing quality.
Summary of the invention
The objective of the invention is to provide a kind of improvement on existing offset press basis, it is big to have a printing format, and paper distortion is little, complete many chromatographys offset press of opening of highly versatile.
Technical characterictic of the present invention is: at complete many chromatographys offset press of considering to be designed on the high basis of highly versatile, printing precision to be made up of paper feed mechanism, first printing assembly, general printing element, paper collecting mechanism, frame; Paper feed mechanism links to each other with frame; First printing assembly is arranged on the frame; On frame, be provided with at least one group of general printing element, be connected through bolt between the adjacent general printing element; On frame, be provided with paper collecting mechanism, the impression cylinder in the described general printing element, the diameter of transfer roller are the doubly footpath of plate cylinder, blanket cylinder; Described impression cylinder is provided with stings paper Ya Kaiya torsion spring device.
The diameter of the impression cylinder of described first printing assembly is the two-around of plate cylinder, blanket cylinder.
Described general printing element is made up of impression cylinder, transfer roller, plate cylinder, blanket cylinder, ink system, frame wallboard; The diameter of impression cylinder, transfer roller is the doubly footpath of plate cylinder, blanket cylinder, and described ink system is provided with scurries black position adjusting mechanism.
The impression cylinder of described general printing element by cam, open tooth lever, cylinder, housing screw, open the tooth spin, cutting ferrule, square torsion spring, sting paper tooth axle, torsion regulating sleeve, regulate holder, torsion adjustment frock hole, sting teeth and form; Opening the tooth spin is fixed on out on the tooth lever; Open the tooth lever and be fixed on through housing screw and sting on the paper tooth axle, cutting ferrule is fixed on to be stung on the paper tooth axle, and an end of square torsion spring is through in the cutting ferrule; The other end is through in the torsion regulating sleeve; Clamp through clamping screw by regulating holder, and be fixed on the cylinder, described cam is arranged on the cylinder.
During work, energized, complete machine begins to get into the seal state of treating; When pressing play button, paper feed mechanism separates paper from pile automatically, and paper is delivered to well-behaved mechanism place; Paper gets into first printing assembly and carries out the first impression; Under the drive of paper product transfer roller in general printing element of printing, get into general printing element and carry out the second impression, under the effect of next stage printing element transfer roller, get into the 3rd printing element after the second impression is good again, completion is printed after multistage printing element printing; Under the effect of paper collecting mechanism, printing is received foldedly, accomplished whole printing process.What of trapping printing can superpose according to required requirement in the printing element, reach many chromaticity printings; Double its objective is in order to reduce the bending of seal paper in printing is transmitted that the diameter of the impression cylinder in first printing assembly is designed to plate cylinder, blanket cylinder diameter reduced distortion and design; Impression cylinder in the general printing element, the diameter of transfer roller are designed to the two-around of plate cylinder, blanket cylinder; Its purpose also is in order to prolong the time in the transfer; It is dry to be convenient to print China ink, reduces the flexural deformation of paper, designs to improve printing precision; To be provided with in the general printing element and to scurry black position adjusting mechanism, to its objective is in order easily the inking position being regulated to be provided with; Impression cylinder is provided with stings paper Ya Kaiya torsion spring device and its objective is to regulate for ease and sting the paper tooth power of gritting one's teeth of paper is provided with.
Advantage of the present invention is: because the diameter of impression cylinder, transfer roller is designed to the two-around of plate cylinder, blanket cylinder, thereby reduced the bending of paper, printing precision is improved; Owing to take the pattern of the general printing element stack of many groups to make up, thereby can be superimposed as required chromatography offset press as required; Owing to be provided with and scurry black position adjusting mechanism, thereby can in time regulate to printing the big position of black consumption, reduced the consumption of printing ink, improved printing quality simultaneously; Owing to be provided with and sting paper Ya Kaiya torsion spring device, thereby can regulate the pressure of stinging paper easily; Since rational in infrastructure, highly versatile, printing format is big, and printing quality is good, so very big practical and popularizing value is arranged.
