[0064] The gas inlet 4013 is connected with the second pipeline 402, and the two are installed through the installation flange 4021, and the gas outlet 4014 is connected with the nozzle 403, and threads can be arranged at the gas outlet 4014, and the nozzle 403 is screwed to realize the installation.

[0065] Further, the power source 301 and the gas source are respectively connected with a control system, and the control system is used for controlling the action of the power source 301 and the flow and flow rate of the gas provided by the gas source.

[0066] Specifically, the control system is integrated on a blade redrying machine control electric cabinet, and the control system comprises a first controller and a second controller, the first controller is connected with the power source 301, when the power source 301 is a pneumatic cylinder 3011, the first controller is connected with a first electromagnetic valve and a speed regulating valve on the gas path in the pneumatic cylinder 3011, the movement of a piston rod 3012 in the pneumatic cylinder 3011 can be controlled according to the on-off of the first electromagnetic valve, and the speed of the movement of the piston rod 3012 can be controlled by adjusting the opening size of the speed regulating valve.

[0067] The second controller is connected with the gas source control, the gas source is connected with the second pipeline 402, a stop valve, a filter and a second electromagnetic valve are arranged on the pipeline connected with the gas source, the second controller is connected with the stop valve and the second electromagnetic valve, whether the gas source supplies gas is realized by controlling the opening and closing of the second electromagnetic valve, and the flow rate and flow of the steam are controlled by adjusting the opening of the stop valve.

[0068] When the screen plate 20 is cleaned, an operator manually starts the cleaning program through the blade redrying machine control cabinet configuration screen, the control system sends instructions through the configuration screen, controls the opening and closing of the first electromagnetic valve in the gas circuit, and drives the piston rod 3012 of the air cylinder 3011 to move downward, drives the connecting rod 302 connected with the piston rod 3012 and the first pipeline 401 connected with the connecting rod 302 to move downward, until the nozzle 403 approaches the surface of the screen plate 20, when the gas circuit supplies gas, the movement of the piston rod 3012 is ensured to be stable by controlling the speed regulating valve, so as to avoid impacting the screen plate 20;

[0069] When the first pipeline 401 moves to the cleaning position, the control system automatically opens the second electromagnetic valve, the gas source provides steam into the second pipeline 402 and the first pipeline 401, and the nozzle 403 realizes uniform steam spraying, so that the steam covers the entire surface of the screen plate 20, and effectively removes the tobacco residue and dirt attached to the screen plate 20.

[0070] During the cleaning process, an operator can adjust the steam pressure, cleaning time and cleaning frequency and the like in real time through the configuration screen, so as to adapt to different working conditions and cleaning requirements, when the cleaning is completed, the control system automatically closes the second electromagnetic valve of the gas source, stops the gas supply, and then drives the piston rod 3012 to move upward, drives the first pipeline 401 to move upward to the initial position, and completes the entire cleaning process.

[0071] In summary, through the device, the screen plate 20 can be kept unobstructed, the blade redrying processing quality is not affected due to the screen plate 20 being blocked, the labor intensity is reduced, the cost is saved, and the efficiency is improved.
