On The Remote Control System For Ink And Maintenance Technologies
Through the years on the ROLAND 700 Sheet-fed offset press Maintenance, the author summarizes some ink remote system maintenance and maintenance experience, would like to discuss with industry colleagues.
ROLAND 700 Offset printing Machine a color group from 34 individual ink keys control the ink, each ink key components further from the blade (knife, knife tray, advance and retreat stent device) and gear box (motor, precision potentiometer, deceleration gear and motor drive circuit board) of two parts, the exact match between the various components is particularly important.
In the printing process, in order to make uniform ink distribution of natural, vivid colors, they must control well the various parts of the ink. ROLAND700 automatic ink system uses high-precision potentiometer location of the ink keys back to the computer center, from the console to set ink key value, through the ink key position on the stepper motor to drive the ink keys, so that ink key within the movement in the appropriate schedule to the ink tank of the ink distribution required to ensure that the ink on the ink roller bit of ink thickness accurately.
Press after a period of running, the parts will be some wear and tear, the control system may also produce errors, and therefore should periodically clean the knife open the ink tank, ink on the remote control system for maintenance and maintenance.
Installed in the leak-proof plastic and ink keys should note the following:
1. In a plastic slot on the plastic pallets before, should be in the plastic tank and plastic tank surrounded by a thin layer of grease, then glue evenly on the ground at leak-proof plastic tank, leak-proof plastic pallet surface to be more than 3 4cm, on the cover of the glue the same way with this.
2. Ink key component in the installation, adjust the blade support shaft section of the copper nut, the front blade on both sides of the semicircle trough placed in the plastic pallet plastic tank on the Department’s leak, tighten the screws, installed later leak-proof plastic squeeze ink knife, the knife between the two leakproof plastic tank from a semi-circular extrusion, resulting in plastic columns, so that you can more effectively prevent ink leakage.
3. Ink knife blade bracket can swing around, which is to the knife when in contact with ink roller will not produce deviation caused by unevenness of ink, so when the last fixed blade must be 34 from both sides of the blade squeeze tight, leaving no gap between the knife so the knife and the ink roller in contact with the front office lined up.
4. Installed in the gear box when the component to the knife, make the gear box output shaft of the notch aligned blade rotating the nut on the rear components of the slot, or blade components of two fixed feet pressure can easily be broken.
5.34 ink key board is 26 lines in parallel, with address strobe inspection, patrol control methods. The use of hand-held terminal regulator check, sometimes find more ink key circuit problems, and in fact may be only a circuit board damage and affect the normal other circuit board inspection, then take one by one check, to find damage The piece of circuit board.
