Detailed description of the invention
The object of the present invention is achieved like this, and the reverse-printed roller diameter that it is used is different from positive forme roller diameter.Thickness according to aluminium foil, width, the parameters such as oven temperature, length, pull strength, use the stress-strain relation of plasticity, set up stress-strain diagram, according to the model parameter of material, calculate aluminium foil elongation after drying for the first time, so reverse-printed roller girth is also increased a corresponding length than positive forme roller girth, controlling with electronics register sets, realize the alignment of positive and negative print smoothly, alignment precision is up to ± 0.1mm.
nullThe high speed medical aluminum foil printing machine positive reverse-printed registration device designed according to this method，At least include web-like aluminium foil unwinding unit 1 and web-like aluminium foil rolling unit 11，The first positive red ink paste used for seals 2 is had successively between web-like aluminium foil unwinding unit 1 and web-like aluminium foil rolling unit 11、Second positive red ink paste used for seals 3、3rd positive red ink paste used for seals 4、It is coated with protection glue 5、Lower floor's baking oven 6、First reverse-printed color 7、Second reverse-printed color 8、It is coated with adhesive glue 9、Upper strata baking oven 10，Web-like aluminium foil successively with web-like aluminium foil unwinding unit 1、First positive red ink paste used for seals 2、Second positive red ink paste used for seals 3、3rd positive red ink paste used for seals 4、It is coated with protection glue 5、Lower floor's baking oven 6、First reverse-printed color 7、Second reverse-printed color 8、It is coated with adhesive glue 9、Upper strata baking oven 10、Web-like aluminium foil rolling unit 11 Dynamic link library，It is characterized in that: have on web-like aluminium foil and just printing reverse-printed alignment mark line，At the second positive red ink paste used for seals 3、3rd positive red ink paste used for seals 4、First reverse-printed color 7、Second reverse-printed color 8 side is respectively arranged with detector unit (first detector unit 13 or the second detector unit 14 or the 3rd detector unit 15 or the 4th detector unit 16)，Detector unit is for detecting the mark line of web-like aluminium foil，Detector unit electrically connects with to version EOC 12，Version EOC 12 is electrically connected with roller servomotor，During aluminium foil，With detector unit (first detector unit 13 or the second detector unit 14 or the 3rd detector unit 15 or the 4th detector unit 16) the detection mark line of assorted printing element，When detector unit detects mark line，First detector unit 13 or the second detector unit 14 or the 3rd detector unit 15 or the 4th detector unit 16 export a signal to version EOC 12，Version EOC 12 is detected output signal and the corresponding chromatography output signal time difference，Control roller servomotor，Rear color marker is made to align with front color marker，Make just to print with reverse-printed set accurately.
Aluminium foil arrive tertiary color front printing 4 to the second color front printing 3 and enters the baking of lower floor more than 200 DEG C by being drawn to the first color front printing 2 again through being coated with protection glue 5 and carry out case drying by web-like aluminium foil unwinding unit 1 more again, then carries out arriving web-like aluminium foil rolling unit 11 after the first color back face printing 7 enters upper strata baking oven 10 drying again to the second color back face printing 8 again after being coated with adhesive glue.
Second color, the printing of tertiary color front and the first color, the second color reverse-printed are equipped with detector unit (probe), and detector unit is photographic head or a pair luminous tube and photoelectric receiving tube.Color marker line and front color marker line alignment error after detector unit detection, when there is error, will be to version EOC 12 output signal, version EOC 12 is controlled roller servomotor, color version roller angle position after change, color and the alignment of front color after realization, reverse-printed roller diameter is to increase an elongation by the elongation calculating in aluminium foil drying course than positive forme roller girth to determine.
The principle of the present invention is as shown in Fig. 2 A, Fig. 2 B, aluminium foil can produce permanent deformation by more than 200 DEG C oven for drying under the effect of pull strength, produce an elongation, this uses plasticity stress-strain relation, model parameter calculation elongation according to material, is revised reverse-printed roller diameter, increases an elongation than positive forme roller girth, make reverse-printed identical with the angle position of positive forme roller, then with electronics, version fine setting is realized the alignment precision of positive and negative print.
In the present embodiment, positive and negative red ink paste used for seals is several to be designed according to user's request.
If medicinal aluminum foil to be coated with after dry color just prints protection glue after, by more than 200 DEG C oven for drying, under the traction of transmission tension force, aluminium foil can extend, produce permanent deformation, during such reverse-printed will be just patterned alignment, depend merely on electronics to version dress control be difficult to.
It should be noted that parts that the present embodiment describes the most in detail and structure belong to well-known components and the common structure of the industry, some operating process belongs to the conventional of the industry or well-known operations process, describes the most one by one.
