When certain ultraviolet LED group passes through the switch connection power supply of its correspondence, this ultraviolet LED group is energized and sends the ultraviolet light of respective wavelength.
Each ultraviolet LED in same ultraviolet LED group can connect by mode that is in parallel or series connection, and the mode that also series and parallel connections can be adopted to combine connects.
During production, according to the characteristic of UV ink used, determine one or several wavelength of this ultraviolet light needed for UV ink solidification, then two or a switch in closed corresponding switches set 74, make one or several ultraviolet LED group 73 corresponding to this one or several wavelength or the energising of one of them ultraviolet LED group, and send the ultraviolet light (other unwanted ultraviolet LED groups 73 or ultraviolet LED group are then in off-position) of respective wavelength, these UV-irradiations, on the UV ink layer of spray printing, can effectively impel the UV ink layer of spray printing to solidify.
The operation principle of brief description once this spray code spraying apparatus:
Paper feeding unit 8 can store the stacked paper treating coding, is separated by stacked paper and sends on delivery platform 9 front end one by one; When paper 17 arrives delivery platform 9 rear end, front lay positioner 10 and side mark positioner 11 position paper 17 jointly, make this paper 17 being about to be sent to coding cylinder 2 arrive on coding cylinder 2 exactly in position; By front feeding mechanism 3, paper 17 is passed to coding cylinder 2 subsequently, the paper of holding in the month on coding cylinder 2 is grited one's teeth and 5 is held paper in the month, and suction hole 6 air-breathing simultaneously on coding cylinder 2 surface, is adsorbed on the surface of coding cylinder 2 by paper 17; Coding cylinder 2 rotates and paper is delivered to successively code spraying head 1 and UV ink curing device 7 position, carry out spray printing when paper 17 needs the position of coding to march to below code spraying head 1, when coding position marches to UV ink curing device 7 position, carry out UV solidification process; Hold paper subsequently in the month to grit one's teeth 5 relieving paper 17, by rear feeding mechanism 4, the paper 17 completing spray printing is passed to collection conveyer belt 12, the paper 17 completing spray printing is delivered to delivery unit 13 and is carried out receipts and fold by collection conveyer belt 12.
Hold in the month paper grit one's teeth 5 hold paper in the month after, drive paper 17 pass through between air roll 14 and coding cylinder 2, utilize the pressing effect of air roll 14 pairs of paper 17, can make paper 17 touch better coding cylinder 2 surface, paper 17 be there will not be and wags the tail and tilt phenomenon.
In other embodiments, the quantity of ultraviolet LED group, the centre of luminescence wavelength of each ultraviolet LED group, the quantity of each ultraviolet LED group medium ultraviolet LED and arrangement mode, all can adjust as required.
In other embodiments, also can be divided into multiple ultraviolet LED group by the ultraviolet LED in some ultraviolet LED group, all the other ultraviolet LED groups are then without separating into multiple ultraviolet LED group; Or each ultraviolet LED group is all without separating into multiple ultraviolet LED group.When ultraviolet LED group is without separating into multiple ultraviolet LED group, corresponding switches set only includes a switch, by unified unlatching or the closedown controlling all ultraviolet LEDs in corresponding ultraviolet LED group of this switch.
