Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, in an embodiment of the present invention, an overprinting cursor includes an unwinding device 5, a printing plate frame 2 is equidistantly disposed on one side of the unwinding device 5, a gravure plate 1 is mounted on the printing plate frame 2, and a plurality of lead rollers 3 are horizontally disposed on an upper side of the printing plate frame 2, so that the lead rollers 3 are matched with the gravure plate 1;

keep away from on the printing plate frame 2 of unwinding device 5 equal fixedly connected with photoelectric scanning head 8, and one side that unwinding device 5 was kept away from to printing plate frame 2 is provided with coiling mechanism 6, and a plurality of printing plate frames 2 are located between unwinding device 5 and the coiling mechanism 6.

The unreeling device 5 is wound with a paper roll 4, and one end of the paper roll 4 is wound on the printing plate frame 2 through the roller 3 and matched with the photoelectric scanning head 8 so as to be conveniently unfolded and placed.

The paper roll 4 passes through the plurality of photoelectric scanning heads 8 to form printing paper 7, and one end, far away from the photoelectric scanning heads 8, of the printing paper 7 is wound on the winding device 6, so that the printing paper 7 can be wound conveniently after being printed.

The photoelectric scanning head 8 comprises a light source 9, two symmetrically arranged lenses 10 are arranged on the lower side of the light source 9, and the lenses 10 are matched with the light source 9, so that the light source 9 can be conveniently irradiated on the overprint marks on the paper roll 4 through the lenses 10, and two focuses are formed on the paper roll 4.

One side of lens 10 is provided with photoelectric cell 11, and photoelectric cell 11 is located the downside of light source 9 and cooperatees with lens 10, and photoelectric cell 11 is connected with the computer through prior art, is convenient for photoelectric cell 11 to record the reflection of the light volume on scroll 4 to be convenient for photoelectric cell 11 will record and carry to the computer in.
