The present invention also provides a kind of sheet-fed to change picture and text printing method.
Description
Technical field
The invention belongs to the technical field that changes picture-text printing, be specifically related to a kind of equipment and method of changing picture and text printed on sheet-fed.
Background technology
In the technical field of printing picture and character, can whether unanimously divide into two classes according to the content of each printing: the first kind is to be called repetition picture-text printing, the content of each printing is all changeless, repetition, conventionally this class printing is all supporting a forme, the picture and text of its printing are engraved on forme in advance, such as traditional gravure, offset printing, thermoprint, impression etc.; Equations of The Second Kind is called variation picture-text printing, the printing figure message content of each paper can independently be set as required, each graph-text content of printing can not repeat conventionally, such as Antiforge, Quick Response Code, label, mark, ticket, sequence code etc., microprocessor can be inputted and be stored in to the data of each system paper impressing pattern in advance, when printing, form different dot matrix patterns by microprocessor control ink gun, realize thus the personalization of every sheet of printing material and print.
The equipment of conventional printed picture and text is divided into two classes: the first kind is printer, and Equations of The Second Kind is printing machine. The two makes a big difference, printer is a minimized office equipment, the scale of construction of whole printer is generally single just can arbitrarily move, generally complete by the assembling of printer manufacturer, without printing again Assembling debugging, printer is provided with printhead (printhead), and the ink using is from print cartridge; Printing machine is heavy mechanical equipment, and the scale of construction of whole printing machine is generally far from single or several people and just can moves, generally need to be in printing house's Assembling debugging; The ink that printing machine uses is from black groove, and ink dips at roller surface and passes to paper again.
In the prior art, owing to repeating picture-text printing for periodically repeating print, therefore generally adopt rotary printer, it has two rollers at least in the time of printing, wherein first roller surface is moistened with and the ink of forme pattern same shape, second roller with first roller compression fit, first roller surface is also provided with gap slot, is provided with and stings paper tooth in gap slot. When rotary printer printing sheet-fed, the paper tooth of stinging of second roller is taken over paper from stinging paper tooth of upstream chart driving mechanism, the paper tooth of stinging of second roller is bitten paper subsequently, paper is rotated in company with second roller, when paper from the point of contact between two rollers through out-of-date, first roller compresses paper, the picture and text ink of first roller surface is just transferred to above paper, finally, the paper tooth of stinging of second roller is rotated further, and paper handing-over is passed to downstream paper splicing mechanism sting paper tooth, so constantly repeat. The feature of cycle type printing equipment is: the girth of a, roller is greater than the length of paper; B, printing parts (being first roller) play the effect of paper location simultaneously, specifically, print moment at each, and first roller is not only responsible for printing, and is responsible for the seal point clamped position of paper; The ink that c, printing machine use is from black groove, and ink dips at roller surface and passes to paper again; D, implement printing owing to need to using pressure between first roller surface and second roller surface, therefore second roller surface must be complete and can not offers pore, otherwise the local location of offering pore just lacks pressure and cannot transmit ink to paper.
Traditional printing changes in the technology of picture and text, because the printing figure message of every paper constantly converts, therefore can not adopt forme, can not adopt rotary printer, and can only adopt printer, for example ink-jet printer. Ink-jet printer is suitable for printing and changing picture and text on sheet-fed, and as shown in Figure 1, it is provided with ink gun 5, ink gun 5 belows are provided with backing plate 6(packing paper member), ink gun 5 sides are provided with paper-sheets rolling wheel 7, drive paper 8 to move by paper-sheets rolling wheel 7, between paper-sheets rolling wheel 7 and ink gun 5, are provided with photocell eye 9. The design feature of ink-jet printer is: while one, printing, packing paper member 6 maintains static, and relies on photocell eye 9 to detect the run location of paper 8; Two, the girth of paper-sheets rolling wheel 7 is much smaller than the length of paper 5; Three, print parts (being ink gun) and can not play the effect of location simultaneously, print between point (being that ink gun is aimed at the some A of paper) and anchor point (being the some B that paper-sheets rolling wheel acts on paper) from a distance. Therefore, in Fig. 1, the distortion such as can not bend of the shape that must guarantee the AB section of paper 8, otherwise will cause printing position inaccurate, and to keep the AB section of paper indeformable, what mainly rely on is exactly the rigidity of paper itself and setting off of backing plate 6 in fact, also requires too fast (otherwise paper is easily out of shape) of paper gait of march. In a word, because the diameter of paper-sheets rolling wheel 7 is little, also require the paper gait of march can not be too fast, make ink-jet printer printing speed be much more slowly than cycle type printing equipment, the number of paper of existing ink-jet printer printing per hour is only equivalent to 1/tens even more than one percent of rotary printer.
And along with the development of planar bar code technology, anti-counterfeiting technology, the demand that changes picture and text printing product significantly increases, rely on merely printer can not meet market demand far away. Particularly, increasing industrial products production line need to be used and change picture and text printed matter, and these printed matters preferably can be assigned on product of correspondence of production line in real time, online, that is to say, on production line, when producing a product, preferably print out a printed matter with variation picture and text and carry out automatic matching simultaneously. Obviously, in prior art, rely on merely printer can not meet the real-time supporting needs of production line far away, therefore can only first print printed matter, print and be over again by manually printed matter being carried out to secondary distribution for product, this extremely trouble that seems.
