Summary of Faults in Cut-size Sheeter Work

A Cut-size sheeter can’t be cut during work, how to solve it?

(1) Use a multimeter to measure the circuit inside the Cut-size sheeter button.

(2) Use a multimeter to stop the safety pin contactor km7, cutting contactor km8, cutting time limit relay kt2 and other circuit positions, safety pin solenoid valve yv3, solenoid valve yv2, and electromagnetic clutch yc2 at the center control position of the front-end circuit In the test, a flat-blade screwdriver is used to connect the circuit at the position of the contactor km8, and it is found that the knife bed can normally cut down and return to its position.

 (3) Check and clear the electromagnetic safety plug. Remove the electromagnetic safety latch. First, remove the two unit line printed bodies that connect the travel switch, remove the hexagonal screw for fixing, slowly draw out 3 sets of electrical roads from the junction of the two ends, and remove the electromagnetic safety pins.

(4) It is found that there is greasy, dirty, rusted and other conditions in the armature seat, and the compression spring, screw, armature seat and other parts of the Cut-size sheeter plug should be cleaned and scrubbed with an appropriate amount of gasoline. When the machine is turned on, the printing paper can be cut normally, and the sound of the safety pin is also rigid and loud.

The above is the summary of the phenomenon that the Cut-size sheeter does not drop the knife. A machine must not only be used well, but also be maintained is the long-term development.
