During printing, motor 6 starts, and motor 6 drives roller platen 5 to rotate, and roller platen 5 passes through driven gear 42 and driving gear
53 engagement drives roller 4 to rotate, and due to ink roller 2, anilox roll 3, roller 4 and roller platen 5 successively tangent setting, ink roller
2 lower part is located in ink tank 1 and in the ink 10 being immersed in ink tank 1, so, ink roller 2 passes ink 10 in ink tank 1
Anilox roll 3 is given, ink 10 is transferred on the areas of the printing plate 40 in roller 4 by anilox roll 3 again, then, by roller 4
Printing pressure between roller platen 5, the ink on the areas of printing plate 40 will be transferred to printable fabric 11 the upper surface of.
The specification of the printing figure message of traditional flexible plate printer is determined by the picture and text on printing plate 40, and printing figure message it
Between interval be to be determined by 4 diameter of roller and driven gear 42, therefore, if to print out the same print of different interval size
Map brushing text, must just replace roller 4 and driven gear 42, this just makes troubles to printing, meanwhile, replace roller 4 and driven tooth
Wheel 42 is also time-consuming and laborious, reduces production efficiency, improves labor intensity.On the other hand, factory need to store the version of a large amount of specifications
Roller 4 and driven gear 42.
For this purpose, designing a kind of can easily print out same printing figure message and the interval between printing figure message can root
According to the flexible plate printer that actual needs is configured, to improve production efficiency, reduce labor intensity, this has become current urgency
The technical issues of need to solving.
Utility model content
Can easily print out same printing figure message the technical problem to be solved by the utility model is to provide one kind and
