The machine I/O box 9 controls the opening of the air pressure balancer 10 according to the received wind pressure fluctuation signal, and then controls the constant wind pressure of the cigarette process.

The working process of the present utility model is:

1. The high-damping air supplement system is a device that simulates the resistance characteristics of the pipe network. It has the advantages of large air supplement resistance, good air supplement effect, small change in main pipe pressure, and small maintenance workload; and it directly supplies air from the main pipe, and the air supplement effect is direct. efficient.

For the centralized negative pressure process dust removal system, each system has its minimum air intake volume. When the system intake air volume is lower than its minimum air intake volume under normal working conditions, the system starts to prepare for supplementary air.

The working principle of the high damping make-up air system is:

The flow meter installed on the air supply pipe 6 of the cigarette machine detects the wind force flow value of the cigarette making machine process, and feeds back the detected wind force flow value to the PLC controller 5, and the PLC controller 5 controls the high flow rate according to the received wind force flow information. The opening of the damping supplementary air valve 2 and the control valve 1;
