Description
Technical field
The utility model relates to a kind of serigraphy production line of figure code steel plate, belongs to figure code Plate Production and manufactures field.
Background technology
Serigraphy is called as four large printing processes together with lithograph printing, protruding seal printing, gravure printing.Serigraphy needs the serigraphy assembly to complete, the screen printing apparatus assembly mainly consists of top 5 factor: screen printing forme, scraper plate, printing ink, print station and stock, wherein, be provided with picture and text part mesh and non-graphic part mesh on screen printing forme, the mesh of picture and text part can see through printing ink, and the mesh of non-graphic part can not see through printing ink.
The basic process of utilizing the screen printing apparatus assembly to be printed is: during printing, pour printing ink in screen printing forme one side, printing ink position with scraper plate on screen printing forme applies certain pressure, make printing ink move towards the screen printing forme opposite side, printing ink is scraped scraper plate and is expressed on stock from picture and text part mesh in movement, because the viscous effect of printing ink makes the trace set within limits, and then the formation picture and text the same with picture and text part mesh.After scraper plate is scraped the whole space of a whole page, lifted, screen printing forme also lifts simultaneously, and printing ink is scraped back to initial position, is so far a print stroke, completes the printing of a kind of color or monochromatic pattern or decorative pattern.
In screen printing process, owing to keeping certain gap between screen printing forme and stock, screen printing forme while making printing produces the reaction force to scraper plate by the tension force of self, this reaction force is called screen resilience, due to the effect of screen resilience, makes screen printing forme and stock be portable line and contacts, and screen printing forme other parts and stock are disengaged position, and then make printing ink and the motion of screen printing forme fracture, therefore, serigraphy has higher dimensional accuracy.In addition, serigraphy, by the extruding of scraper plate, makes printing ink transfer on stock by picture and text part mesh, forms the picture and text the same with original copy, and its equipment is simple, easy to operate and with low cost.Serigraphy at present has been widely used in the printing of paper, and common serigraphy product has: colored oil painting, pictorial poster, business card, binding and layout front cover, product tag and dyeing textile product etc.
At present, screen printing technique is applied on steel plate by turning of success, to form printed layers comparatively abundant and that third dimension is stronger on steel plate.Yet, the printing precision of serigraphy is lower with respect to the intaglio printing technology, in order to obtain dimensional printed chart code or the striped that precision is higher, and guarantee that decorative cover has printed layers abundant and that third dimension is stronger, existing a lot of manufacturers attempt serigraphy and intaglio printing are combined, before serigraphy, adopt gravure printing apparatus to carry out the roller coat of background color decorative pattern, and after roller coat, adopt screen printing technique to realize abundant printed layers.
The existing roll coating apparatus assembly of realizing roller coat, comprise feeder apparatus, for coating is provided; The suction roller, its periphery is connected with described feeder apparatus, has a plurality of depressions that form image-region when filling with described coating on described periphery; The rubber-coated roller, its periphery is connected with described suction roller, the image-region formed on described applicator roll for accepting described coating, and described image-region is transferred on steel plate to form needed chromatic pattern.
Yet, the applicant states in the use in the roll coating apparatus component process and finds, the roll surface speed of described applicator roll, suction roller is often inconsistent with the process speed of whole production line, and the rotating speed that whole production line lacks described suction roller and applicator roll carries out the control system of adjusting on line, thereby cause moving a period of time by often stopping the line adjustment at whole production line, and then affected the efficiency of whole production line; And if do not stop the line adjustment, will to cause transporting the roll surface speed of the speed of steel plate and each roller inconsistent, and then often cause carrying out the roller coat transfer printing to steel plate according to preposition; In addition, in order to print multi color effect, often need several groups of roll coating apparatus assembly synergistic runnings, and above-mentioned roll coating apparatus assembly of the prior art lacks a kind of adjacent roller automatic doubler surface glouer assembly quantity-produced control system that makes, that is, need the staff whether a kind of color to be applied by first roll coating apparatus assembly of eye-observation, after definite the coating, by manually starting adjacent roller automatic doubler surface glouer assembly, thereby make between adjacent roller automatic doubler surface glouer assembly, can't realize continuous production again; Simultaneously, owing to lacking the control system that the rotating speed of suction roller and applicator roll is adjusted, thereby can't when the pattern dislocation of adjacent roller automatic doubler surface glouer assembly printing, carry out error correction.
In sum, when in the serigraphy production line, draw roll automatic doubler surface glouer assembly carries out the polychrome roller coat of priming paint, how the roll surface speed of each roller in the roll coating apparatus assembly is adjusted and made the roll surface speed of each roller consistent with the technique rotating speed, and then to enhance productivity be also there is no the technical barrier solved in prior art.
