A paper -cutting machine does not show a knife in the work. After using a multimeter to measure related circuits, check the electromagnetic clutch site, and use local disassembly and liquidation of electromagnetic clutch installation, clearing the prices of oil pollution printing.
(1) Use a universal meter to measure the internal circuit of the button to show normal.
(2) In the control location of the center of the front circuit of the fuselage, the multimeter has successively used the circuit position of the Ping An In contactor KM7, the tailoring contactor KM8, the time -cut relay KT2 and other circuits and the Pingan -sale solenoid valve YV3, the solenoid valve YV2 and the electromagnetic clutch YC2 stopping Testing Zhengzhou printing is normal, but it is always impossible to get off the knife during the practice test. At this time, the flat screwdriver knife was connected to the contact car KM8 position, and it was found that the knife bed could be cut and returned normally.
(3) Check and settle electromagnetic safety insertion. Remove the electromagnetic safety insertion. First unload the two unit line prints of the connection itinerary switch, remove the hexagonal screws used to fix, and slowly draw 3 sets of electricity roads from the two ends (pay attention to the roadkin of the 77th logo, beware of scattered) printing) Price, unload electromagnetic safety sales.
(4) Discover greasy, dirty, rust and other conditions in the tissue, and stop liquidation and scrubbing in an appropriate amount of gasoline for the interpretation of the embarpper, screw, and toddic iron, and other parts. The booting operation can be printed on the knife normally. At the same time, the sound of Ping An's suction and combination also has a sense of rigidity.
