Description

Two nameplate printing machines

Technical field

The utility model belongs to print field, relates in particular to a kind of two nameplate printing machine.

Background technology

1439, the paddy Rustenburg of Germany produced wooden letterpress, although that this vertical spin formula hand is pulled printing machine is simple in structure, had continued to use 300 years; 1812, the Ke Nixi of Germany made First circle and flattens letterpress; 1847, the Huo Yi invention rotary press of the U.S.; 1900, make six look rotary press; 1904, the Karl Ruberl invention offset press of the U.S..

Before twentieth century fifties, traditional letterpress technique occupies dominant position in press, and the development of printing machine is also take letterpress as main.But metal letterpress technique exists, and labour intensity is high, the production cycle long and the shortcoming of contaminated environment.From the sixties, there is cycle offset lithography technique short, productivity ratio high and start rise and development, metal letterpress is replaced by lithographic offset printing gradually.Soft letterpress, porous printing, electrostatic printing, ink jet printing etc., also developed aspect packages printing, advertising and printing.

World's printing machinery has been obtained larger development since the eighties in 20th century.Over more than 20 year, the development experience of printing machinery three phases.

First stage is initial stage early 1980s to the nineties, and this one-phase is the period of great prosperity of offset printing technological development. the sheet-fed offset press maximum print speed in this period be 10000 seals/hour.Pre-adjustment time before a four-color press printing was generally about 2 hours.The automatic control of printing machine mainly concentrates on automatic detection and the China ink amount aspect such as adjusting and alignment remote control automatically of automatically tying paper, automatically paper collecting, automatic cleaning, mass colour.This period, each sheet-fed offset press manufacturer nearly all also had the manufacturing capacity of four-color machine except monochromatic, double-colored machine, and paper turning mechanism can be manufactured in most commercial cities of manufacturing, and carries out printed on both sides.

Second stage is end of the century early 1990s to 20.Enter the nineties in 20th century, take sheet-fed offset press as mark, printing machinery designing and manufacturing level has striden forward major step in the world.Compared with the type of first stage, the speed of type of new generation further improves, by 10000 seals/hour bring up to, 15000 seals/hour, before printing, the pre-adjustment time also shortened to about 15 minutes greatly by about 2 hours of the first stage.The gentle production efficiency of Automated water of machine also improves greatly.

Since entering 21 century, printing machinery welcomes the 3rd developing stage.At present, some type of sheet-fed offset press can reach 17000-18000 print/hour, but the raising of printing machine maximum print speed is not done one's utmost to pursue by manufacturer, but by the application of information technology, further shorten the time that prints front time and change living-article and pursue more high efficiency.

Aspect printing machinery automation, networking, produce integrated, Digital Workflow, become the emphasis of exploitation with technology such as linking of management information system (MIS).The CP2000 automatic control system of Heidelberg company except to full machine from paper feeding, defeated paper and lead paper, inking, water delivery, plate change, alignment, cleaning, dry, glazing coating, dust and each working link such as collection carries out preset, regulation and control and fault diagnosis, the function such as image deal with data (CIP3/PPF or CIP4/JDF data) before also thering are the whole production process networkings of the printing enterprise of realization, online transmission and printing.Enter the new century, most offset press manufacturing firm has all developed corresponding DI digital printer.

In the technical scheme that realizes prior art, find that prior art exists following technical problem:

Because the data of the nameplate of printing machine are extremely important, and for printing machine, its working environment is not very good conventionally, and the time has been grown the problem that can cause the data of single nameplate to see clearly.

Accompanying drawing explanation

The structure chart of two nameplate printing machines that Fig. 1 provides for the utility model;

The circuit diagram of the paperboard circuit that Fig. 2 provides for the utility model;

The body structure figure that Fig. 3 provides for the utility model.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

The utility model provides a kind of two nameplate printing machine, this structure as shown in Figure 1, described printing machine comprises printing machine body 300, and printing machine body 300 comprises: paper feeding device, paper positioning device, Web transfer apparatus, printing equipment, inking and damping device, delivery device and operating platform; Wherein, printing machine body 300 also comprises the nameplate case 301 that is fixed on printing machine body;

Nameplate case (as shown in Figure 3) comprising: casing 302, sliding door 303, door lock 304 and two nameplates 305, wherein two nameplates 305 are separately fixed at front (as shown in Figure 1) and the back side (as shown in Figure 3) of sliding door 303.

Two nameplate printing machines that the utility model provides; by two nameplates are set at the body of printing machine; and a nameplate is in front; a nameplate overleaf, if positive nameplate damages, because the nameplate at the back side is in casing; it is preserved can be relatively good; so in the case of not affecting the use of normal nameplate, a nameplate for subsequent use is also set, so it has advantages of the nameplate of protecting.

Optionally, paperboard circuit is installed in above-mentioned paper feeding device, this paperboard circuit as shown in Figure 2, comprising: power supply 110, light source 111, photoelectric sensor 101, comparator 102, triode 103 and alarm lamp 104; Wherein, power supply 110 is electrically connected with light source 111, and one end of photoelectric sensor 101 is connected with DC source (DC), and output is connected with the reverse input end of comparator 102, the positive input of comparator 102 and normal voltage VC ₁connect, comparator 102 is connected with the base stage of triode 103, the colelctor electrode of triode 103 and voltage source V C ₂connect, the emitter stage of triode 103 is by alarm lamp 104 ground connection.

Its principle is: in the time of paper feeding device paper feed, if number of paper is one, because now number of paper can be fewer, the intensity that light source 111 sees through paper arrival photoelectric sensor 101 is stronger, now the positive input voltage of comparator 102 is less than the voltage of reverse input end, comparator 102 output low levels, triode 103 cannot conducting, in the time that the quantity of paper is two or multiple, because now quality quantity is thicker, affect light source 111 less through the intensity that reaches photoelectric sensor 101 of paper, now the positive input voltage of comparator 102 is greater than the voltage of reverse input end, comparator 102 is exported high level, triode 103 conductings, alarm lamp 104 is lighted, thereby remind operator's number of paper too much, there is paperboard.

Optionally, described printing machine also comprises multiple cameras, and described multiple cameras are arranged on top and the bottom of printing machine body.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
