JR242 flexographic plate printer is characterized by long printing length (190-400mm),
easy register, stable control of tension, non-dislocation when starting up, and quick drying.
1. Unfolding part:
The rolling out tension can be made by adjusting the friction plate, spring and nut on
the rolling axle. The tension of the material on the rolling out axle can be made by
inserting a stainless-steel rod into the paper.
2. Photoelectric switch:
There are two modes in the setting: ON and OFF. When the machine is in the ON mode,
the photoelectric switch must be screened by the material for the machine to start up. When
the material has been printed, the machine stops working.
Tension roller: The tension roller is used to control the tension of the rolling out
material. When the material is found looser and looser in the process of printing when
passing the tension roller and the tension presser, the rolling out tension must be adjusted
greater (there is adjusting knob in the electric part.)
Unfolding roller:
It has synchronization function when the material passes this structure.
3. Printing station:
The printing station is composed of the front and two colors on the back, of which
one-color group is made of printing cylinder, paired gear anilox roller, ink duct, movable
plate, hand wheel, and registering device when the machine stops.
The size of the printing cylinder and the paired gear can be changed. (for details, please
refer to Measurement Table)
The anilox roller is set at 200 lines per inch when the machine leaves the factory. When
dot pattern is printed, the anilox roller can be selected by the ratio of 4 to 1. The cleaning
of the anilox roller is very important, because the color will become dim when the anilox
roller is blocked by ink.
4. Ink duct:
The ink duct is composed of ink knife, duct distributor and ink adjusting screw. When
the ink duct is mounted on to the machine, the screws at both sides of the ink duct must be
adjusted so that the ink distributor touches slightly with the ex-circle of the anilox roller.
When the anilox roller is turned with hand, it must be turned smoothly.
