Ⅰ. Machine Performance Introduction
1. Using precision motors and linear guides combined to make the blade holder printing
stable.
2. Double-knife printing pressure uses the precise throttle valve behind the upper
cylinder to set the blade speed, avoiding resonance.
3. The printing base can be lifted up 450 and fixed to facilitate scraper loading and
unloading and screen cleaning.
4. The print base can be moved forward to fit the position of the steel plate pattern for
better printing effect.
5. The high and low setting of the double scraper of the printing seat can be adjusted.
6. Printing plate and steel plate spacing, with fine adjustment bar scale setting.
7. Machine arm can be adjusted separately for 470 to 750mm different sizes.
8. The modular printing platen has a groove and positioning PIN, and the setting is
simple. It is easy to change and is suitable for production of single-sided substrates
and double-sided substrates.
9. The calibration plate method using arm (steel plate) movement and print (platen)
X.Y.Z correction adjustment. Convenient and quick.
10. Pneumatic adopts microcomputer PLC control, man-machine interface touch control,
and can freely choose single/double stroke printing.

VI. Machine Operation and Adjustment Essentials
1. Machine Station Origin Confirmation:
After starting up (power transmission), the original point of self confirmation.
2. Zero Setting Essentials:
Select the steel plate block rising down key, the steel plate down
to the beginning point, the use of a ruler or PCB placed between the table and the seat
into a horizontal line, while the distance between the mobile rotation scale to zero set,
according to the thickness of the PCB to determine the printing spacing (generally
according to the board thickness plus 40)
3. Printing setting Mode:
The machine adopts movable positioning PI positioning, please according to the steel
version of the sketch, put the PCB to the platform in a moderate position.
4. Version setting method:
After completing the above (2) action, manual correction (Proofreading the print base and
the printed circuit board) is performed again.
For version guidelines: first set the R.C.L or pairing angle, after finding the target, fix the
steel plate and use the platen to fine-tune the correction.
5. Printing Itinerary Setting Mode:
After the completion of the PCB set alignment, and then use the printing block after the
two induction switch, according to the steel version of the design, printing size set left and
right induction switch position.
6. Knife assembly method:
The knife is assembled using a center screw type. The center hole of the aluminum
handle of the knife is used to fix a screw in accordance with the center of the knife.
7. Knife Height Adjustment Mode:
First loosen the adjustment button's fixed screw, adjust the screw height namely is the
knife height adjustment way.
8. Knife Elevation Adjustment Mode:
Knife inside and outside use a single screw control elevation, front and rear screws need
to be adjusted at the same time to control the knife front and rear elevation.
9. Printing Speed setting:
(1) Printing gap: 2.0mm (general substrate thickness plus 40mm)
