[0049] When used specifically, the following processes are included:

[0050] In the first step, the staff installs the self-cleaning device of the cigarette conveying system at the lower end of the cigarette conveyor belt. Then, the staff turns on the power of the cigarette conveyor belt, manually turns on the power and air source of the self-cleaning device of the cigarette conveying system, or sets the operating time of the power and air source of the self-cleaning device of the cigarette conveying system according to actual needs.

[0052] In the third step, the staff observes the dust and debris stored in the dust bin 26. If the dust and debris stored in the dust bin 26 are full, the staff will turn off the power and air source of the self-cleaning device of the cigarette conveying system, open the dust exhaust port of the dust bin 26, and clean the dust and debris in the dust bin 26. After cleaning, the staff will close the dust exhaust port of the dust bin 26, and then open the power and air source of the self-cleaning device of the cigarette conveying system to let it.

[0053] The fourth step is to manually shut down the power supply and gas supply of the self-cleaning device of the cigarette transport system after completing the required workload, or to automatically shut down the power supply and gas supply of the self-cleaning device of the cigarette transport system according to the settings.

[0054] The above steps can be completed by the staff manually turning on or off the power and air source of the self-cleaning device of the cigarette conveying system to complete the cleaning work, or by setting a time to allow the self-cleaning device of the cigarette conveying system to automatically turn on or off the power and air source. The following is the automatic cleaning working principle of the self-cleaning device of the cigarette conveying system.

[0055] The staff connected the input point X2 in the electrical device 5 to the external start button, X3 to the external stop button, the S / S common terminal to the power supply MX2401 (DC0V), Y0 to the AC motor starting coil K1, Y1 to the blowing solenoid valve K2, and Y3 to the operation indicator light.

[0056] During automatic cleaning, the external start signal X2 is input, the Y1 air blowing solenoid valve actuates K1, the Y0 AC motor coil is energized to start cleaning, and the Y3 running indicator light is on. When the external signal X3 is input, Y1 is disconnected, the solenoid valve closes the air blowing, the Y0 AC motor coil is disconnected, cleaning stops, and the Y3 running indicator light stops.
