Referring to fig. 2, the first control switch is the normally opened contact 51 of the first relay 5.Device further includes second branch 6, the
Two branches 6 are equipped with the second coil 52 of the second control switch and the first relay 5.Wherein, when the second control switch is in closure
State, the second coil 52 of the first relay 5 in second branch 6 it is electric, the first relay 5 in the first branch 4 it is normally opened
Contact 51 is closed.
By the closure and unlatching of the second control switch in control second branch 6, the first relay in second branch 6 is controlled
5 the second coil 52 whether it is electric.
Referring to Fig. 3 and Fig. 4, the second control switch is the normally opened contact 71 of the second relay 7.Device further includes third branch
8, third branch 8 is equipped with the tertiary coil 72 of third control switch and the second relay 7.Wherein, when third control switch is in
Closed state, the tertiary coil 72 of the second relay 7 on third branch 8 it is electric, the second relay 7 in second branch 6
Normally opened contact 71 is closed.
Using the normally opened contact of the first relay 5 and second 7 two relay logical control contactors 3 of relay, realize
Forceful electric power and light current and isolation, also achieve vulnerabilities scan forceful electric power.
Referring to fig. 4, third control switch includes hand push button 9.It, in case of need, can be easy using hand push button 9
Realize the control to contactor 3 in ground.
Referring to fig. 4, third branch 8 is additionally provided with scram button 10.When pressing scram button 10, the coil of the second relay 7
Power loss.Scram button 10 is set, convenient for disconnecting emergency power supply manually when needed, improves the convenience that equipment uses.
Referring to fig. 4 and Fig. 5, packing machine power control further include indicating equipment 12, the coil electricity with the second relay 7
Connection, indicating equipment 12 are configured to issue indication signal when the tertiary coil 72 of the second relay 7 obtains electric.
In some embodiments, indicating equipment 12 includes indicator light or alarm.When indicating equipment 12 issues instruction letter
Number, illustrate that emergency power supply has been powered on.
In some embodiments, breaker 2 is configured to the disconnection main road 1 when overloading or being short-circuit occur in main road 1.
In some embodiments, referring to Fig. 1, main road 1 is additionally provided with primary power source control switch 13, primary power source control switch
13 connect with the normally opened contact 31 of contactor 3.
Above-described embodiment is discussed in detail with reference to the accompanying drawing.
Referring to Fig. 1, packing machine power control includes primary power source control switch 13 and breaker 2.It breaker 2 and connects
The normally opened contact 31 of tentaculum 3 is connected with primary power source control switch 13.
Breaker 2 is configured such that jump Electricity Functional when circuit keeps overcurrent, overload.The normally opened contact 31 of contactor 3
Realize mechanical power transmission function.
In addition, indicating equipment 12 will control on-off by relay K8.
Referring to Fig. 1 to Fig. 3, when pressing emergency power supply start button, the second coil 52 of the first relay 5 must be electric, the
The normally opened contact 51 of one relay 5 is closed, and the first coil 32 for the contactor 3 being serially connected in 220V main road 1 is made to obtain electric, contact
The normally opened contact 31 of device 3 is closed, and emergency power supply is connected.
When pressing emergency power supply scram button 10, the second coil 52 of the first relay 5 is powered off, the first relay 5
