[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] Example 1

[0025] like Figs. 1-2 As shown, an aluminum foil rolling mill lighting control circuit includes an aluminum foil rolling mill, a lighting lamp 7, and a switch 1. The lighting lamp 7 is powered by the aluminum foil rolling mill and is connected to the switch 1. The aluminum foil rolling mill includes a controller 4, which is connected to a start switch 2 and a stop switch 3. A start-up lighting circuit and a stop-down lighting circuit are provided between the controller 4 and the lighting lamp 7.

[0026] The power-on lighting circuit includes a time-delay intermediate relay 5, and the power-off lighting circuit includes a time-delay relay 6. One end of the switch 1 is connected to the live wire, and the other end is electrically connected to the time-delay relay 6 via the time-delay intermediate relay 5. The time-delay relay 6 is connected to the lighting lamp 7, and the lighting lamp 7 is connected to the neutral wire to form a circuit.

[0027] The coils of the time-delay intermediate relay 5 and the time-delay relay 6 are connected to the controller 4.

[0028] The time-delay intermediate relay 5 includes normally open contacts K1 and K2 and normally closed contacts K3 and K4, and the time-delay relay 6 includes normally open contact K5 and normally closed contact K6.

[0029] The switch includes a contact, contact 1, and contact 2.

[0030] The contact 1 of the switch 1 is connected to K3, K3 is connected to K6, and K6 is connected to the lighting lamp 7 to form a first circuit.

[0031] The contact 1 of the switch 1 is connected to K1, K1 is connected to K5, and K5 is connected to the lighting lamp 7 to form a second circuit.

[0032] The contact 2 of the switch 1 is connected to K4, K4 is connected to K5, and K5 is connected to the lighting lamp 7 to form a third circuit.

[0033] The contact 2 of the switch 1 is connected to K2, K2 is connected to K6, and K6 is connected to the lighting lamp 7 to form a fourth circuit.

[0034] For ease of explanation, in this embodiment, the aluminum foil rolling mill operates for 5 hours, with the lighting lamp 7 working for the first 10 minutes. The lighting lamp 7 starts working 5 minutes before the aluminum foil rolling mill stops working, and turns off 10 minutes later and between 4 hours and 55 minutes. Therefore, the delay time of the intermediate delay relay 5 is set to 10 minutes, and the delay time of the delay relay 6 is set to 4 hours and 55 minutes. In this embodiment, there can be multiple lighting lamps 7, which are connected in series.

[0035] In the initial state, the contact of switch 1 is connected to contact point 1. When the start switch 2 is pressed, the controller 4 controls the aluminum foil rolling mill to be energized, and the lighting lamp 7 is energized. At this time, the current flows through contact 1 to K3 and K1. K1 is a normally open contact, and the second circuit is opened. The current flows through K3 and K6 to the lighting lamp 7, and the first circuit is energized and works. At the same time, the controller 4 energizes the coil of the time-delay intermediate relay 5 and the coil of the time-delay relay 6.

[0036] Ten minutes later, the time-delay intermediate relay 5 trips, closing normally open contacts K1 and K2 and opening normally closed contacts K3 and K4, breaking the first circuit and turning off the light 7. At this time, because the time-delay relay 6 does not trip and K5 is open, the second circuit is also broken. The light 7 remains off.

[0037] Until the aluminum foil rolling mill is about to stop working, after 4 hours and 55 minutes, the normally open and normally closed contacts of the time delay relay 6 will activate, K5 will close, the second circuit will be energized, and the lighting lamp 7 will be energized and illuminate.

[0038] When the stop switch 3 is pressed, the controller 4 de-energizes the coils of the intermediate delay relays 5 and 6, and the intermediate relays 5 and 6 immediately reset. Because the aluminum foil rolling mill has stopped due to power failure, the power supply to the lighting lamp 7 is lost, and the lighting lamp 7 goes out.

[0039] After the aluminum foil rolling mill has been operating for ten minutes, the lighting lamp 7 is de-energized. To turn it on, the contact of switch 1 needs to be connected to contact point 2. At this point, K2 is closed, the fourth circuit is energized, and the lighting lamp 7 illuminates. After 4 hours and 55 minutes, the time-delay relay 6 trips, and the lighting lamp 7 goes out.

[0040] At this time, the contact of switch 1 is connected to contact point 1, and the lighting lamp 7 is powered on through the second circuit to emit light, and switch 1 returns to its initial state.

[0041] If, after using the light 7 within the period of 10 minutes to 4 hours and 55 minutes, the light 7 is no longer needed, the contact of switch 1 is connected to contact point 1, and switch 1 returns to its initial state. However, both the first and second circuits are open, so the light 7 is turned off.

[0042] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
