[0035] Optionally, the diverter solenoid valve group 350 includes a first diverter solenoid valve 351, a second diverter solenoid valve 352, a third diverter solenoid valve 353, a fourth diverter solenoid valve 354, a fifth diverter solenoid valve 355 and a sixth diverter solenoid valve 356. The first diverter solenoid valve 351 is arranged in the first air flow channel 311, the second diverter solenoid valve 352 is arranged in the second air flow channel 312, the third diverter solenoid valve 353 is arranged in the third air flow channel 313, the fourth diverter solenoid valve 354 is arranged in the fourth air flow channel 314, the fifth diverter solenoid valve 355 is arranged in the fifth air flow channel 315, and the sixth diverter solenoid valve 356 is arranged in the sixth air flow channel 316. By setting the first flow-dividing solenoid valve 351, the airflow of the first airflow channel 311 can be controlled; by setting the second flow-dividing solenoid valve 352, the airflow of the second airflow channel 312 can be controlled; by setting the third flow-dividing solenoid valve 353, the airflow of the third airflow channel 313 can be controlled; by setting the fourth flow-dividing solenoid valve 354, the airflow of the fourth airflow channel 314 can be controlled; by setting the fifth flow-dividing solenoid valve 355, the airflow of the fifth airflow channel 315 can be controlled; similarly, by setting the sixth flow-dividing solenoid valve 356, the airflow of the sixth airflow channel 316 can be controlled. By controlling the opening and closing states of the first flow-dividing solenoid valve 351, the second flow-dividing solenoid valve 352, the third flow-dividing solenoid valve 353, the fourth flow-dividing solenoid valve 354, the fifth flow-dividing solenoid valve 355 and the sixth flow-dividing solenoid valve 356, the airflow pressure ratio outputted from the first output end 330 and the second output end 340 can be controlled.

[0036] Specifically, the amount of gas flowing through the cross-section of the first diverter solenoid valve 351 per unit time is constant at Q1, the amount of gas flowing through the cross-section of the second diverter solenoid valve 352 per unit time is constant at Q1; the amount of gas flowing through the cross-section of the third diverter solenoid valve 353 per unit time is constant at Q2, the amount of gas flowing through the cross-section of the fourth diverter solenoid valve 354 per unit time is constant at Q2, the amount of gas flowing through the cross-section of the fifth diverter solenoid valve 355 per unit time is constant at Q2, and the amount of gas flowing through the cross-section of the sixth diverter solenoid valve 356 per unit time is constant at Q2; Q1 is equal to 2 times Q2. Through the above-mentioned arrangement, within unit time, the amount of gas flowing through the cross-section of the first diverter solenoid valve 351 is the same as the amount of gas flowing through the cross-section of the second diverter solenoid valve 352, the amount of gas flowing through the cross-section of the third diverter solenoid valve 353 is the same as the amount of gas flowing through the cross-section of the fourth diverter solenoid valve 354, the amount of gas flowing through the cross-section of the fifth diverter solenoid valve 355 and the amount of gas flowing through the cross-section of the sixth diverter solenoid valve 356, and the amount of gas flowing through the cross-section of the first diverter solenoid valve 351 is twice the amount of gas flowing through the cross-section of the third diverter solenoid valve 353.

[0037] Based on the above airflow discharge relationship, the first shunt solenoid valve 351, the second shunt solenoid valve 352, the third shunt solenoid valve 353, the fourth shunt solenoid valve 354, the fifth shunt solenoid valve 355 and the sixth shunt solenoid valve 356, any one or more of the shunt solenoid valves are opened and closed, which can ultimately control the airflow pressure output from the first output end 330 and the second output end 340. For example, when all the shunt solenoid valves are opened at the same time, the airflow pressure output from the first output end 330 and the second output end 340 is equal, and the output state of the first output end 330 and the second output end 340 can be controlled by continuing to control the opening and closing of the third shunt solenoid valve 353 or the fourth shunt solenoid valve 354. When the first shunt solenoid valve 351 and the second shunt solenoid valve 352 are both open and any of the third shunt solenoid valve 353, the fourth shunt solenoid valve 354, the fifth shunt solenoid valve 355, or the sixth shunt solenoid valve 356 is in a closed state, the airflow pressure ratio of the output of the first output end 330 and the second output end 340 can be controlled to be 1:2, 2:1, 1:1, or other combination output modes. In addition, the controller can also simultaneously control the output power of the fan body 100 according to the control conditions of each shunt solenoid valve to adapt the opening and closing quantity of each corresponding shunt solenoid valve.

[0038] In some embodiments, the front end of the input end 320 is detachably connected to a first air pipe 321, and the end of the first air pipe 321 is detachably connected to the air outlet of the fan body 100.

[0039] When using the above-mentioned tobacco equipment fan pressure regulating system, install the fan body 100 in an appropriate position, and electrically connect the shunt solenoid valve group 350 to the controller through the control terminal 360 to ensure that the controller can monitor and control the status of each shunt solenoid valve in real time. Start the system to ensure the normal operation of each component. According to actual needs, adjust the speed and power of the fan body 100 and the opening and closing state of the shunt solenoid valve group 350 to achieve the required airflow pressure and flow output. According to the actual production situation, adjust the parameters of the controller at any time, or manually adjust the opening and closing state of the shunt solenoid valve group 350 to meet the needs of different process links. Regularly inspect and maintain the system to ensure the normal operation of each component. Thereby, it can be ensured that the tobacco equipment fan pressure regulating system can operate stably and efficiently, and meet the precise control requirements of airflow pressure and flow in the tobacco processing process.

[0040] The above-mentioned fan pressure regulating system solution for tobacco equipment can more accurately control the airflow pressure and flow, improve production efficiency, save energy and reduce emissions, and has the characteristics of flexible adaptation to different needs. By adjusting the flow regulating valve group 300 and the pressure regulating valve group 400, the system can achieve precise adjustment of the airflow output to ensure the stability and accuracy of the air flow and pressure required in the tobacco processing process.

[0041] Stable airflow pressure and flow can ensure the normal operation of tobacco processing equipment, reduce production failures and downtime caused by unstable airflow, and thus improve production efficiency and output. Accurately controlled airflow pressure and flow can ensure stable air flow during tobacco processing and avoid product quality problems caused by airflow fluctuations, such as uneven drying of tobacco leaves and inaccurate sorting.

[0042] Each flow diversion solenoid valve in the system can combine different opening and closing states as needed to achieve a variety of airflow pressure ratios between the first output end 330 and the second output end 340 to meet the requirements of different tobacco processing techniques and improve the flexibility and adaptability of the system.

For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
