stapler main circuit

The main motor of the stapler in the main drive part is an electric phosphorus speed-regulating asynchronous motor, which can perform stepless speed
regulation. The secondary side of the transformer "T'" U1 and U2 in the main control circuit are the power sources of the speed regulation system.
    The stapler blade As shown in Figure 7-63a, the main circuit of the machine is shown in Figure 7-63b. Ml is a slip motor, M2 and M3 are cage
motors , QK is the power switch, and FU1, FU2 and FU3 are three motors respectively. Leopard fuses, FR1, FR2 and FR3 are thermal relays for motor overload
protection. 1KM1, 3KM1 and 4KM1 are contactor control switches of the motor.
    The host control circuit of the machine is shown in Figure 7-63c, in which TC is the control transformer. , its capacity is 400W. Primary voltage: 380V. Secondary
voltages are: 170-2Z OV , 30-100V, loo-llov and 6.3-Z OV . VD is a 24V bridge rectifier, used for brake
clutch YB and the power supply of transmission clutch YC; the rectifier element is a 2CZ silicon diode with a rated current of 5A and a maximum reverse operating voltage of
loov. R1 is a shunt load resistor for voltage stabilization, and capacitors C and Rz are connected in series to form a normally open contact 2KM1 Arc extinguishing circuit. HL1-HL8 are
the indicator lights of the corresponding buttons, and the voltage is 6.3V.
    (z) Main control circuit In the host control circuit, KM1 is the control contactor of the main motor Ml. Press button SB2, the contactor KM1
is energized and self-locking, and its main contact KM1 causes the motor M1 to rotate. However, the dry transmission clutch is not closed and the machine does not run. If
you want to make the machine jog, just press the "jog" button SB4. Contactor When KM2 is energized, its normally open contact KM2 will connect the transmission clutch YC, and the machine
will rotate in short motion. SB5 is also a jog button, and its function is the same as SB4. It is installed in other control parts.
    SB6 is the operation control button. Press With this button, the relay Kl is energized, the contact Kl is closed and self-cutting, and its normally open contact Kl is
connected to KM2 to make the machine run. In the circuit of the contactor KM2, the normally open contact K2 is connected in series with another contact Kl, It is
the contact of the power failure relay K2 of the bad book detection control part . When the +12V power supply or 6V power supply of the automatic control circuit of the bad book detection circuit loses voltage, the contact K2 is disconnected and
the machine cannot operate normally because the power supply When the pressure is lost, bad books cannot be detected, which prevents bad books from entering the finished product. If you only stop binding but not
the main motor, just press the stop button SB3. If the contactor KM2 is broken, its main contact KM2 will be disconnected. clutch, the machine stops running
. There are 16 micro switches SB1-SB16 connected in series with the parking button SB3. Among them, SB1-SB8 are the page rolling parking
switches When the page layer is too thick, the The lever will be pushed to disconnect one of the switches, thereby stopping the whole machine. SB9 is a manual lock switch for long vehicles, which is used for locking during
maintenance adjustment; when it is disconnected, the start button on the console cannot start the machine, ensuring To ensure the safety of maintenance operations. SB10~gB13 are
the book rolling switches for each part of the long car respectively, and SB14-SB16 are the book rolling and parking switches for each part of the three-sided knife respectively. Horse riding linkage stapler blade
