Specifically, as shown in fig. 3 to 4, the wind door panel 302 is provided with a rotating shaft 3021 extending to both sides, the rotating shaft 3021 is connected to the mounting plate 301 in a horizontal rotating manner, and both sides of the mounting plate 301 are provided with bearing seats 3012 connected to the rotating shaft 3021. The driving assembly comprises a connecting arm 303 mounted at one end of the rotating shaft 3021 and a cylinder 304 mounted on the mounting plate 301, and a cylinder rod 3041 of the cylinder 304 is connected with one end of the connecting arm 303 far away from the rotating shaft 3021. After the air cylinder 304 is ventilated, the air cylinder rod 3041 extends out to drive the connecting arm 303 to swing upwards, so that the rotating shaft 3021 connected with the connecting arm 303 rotates upwards, and the air suction port 3011 is opened by the air flap plate 302. When the rotating shaft 3021 rotates together with the damper panel 302, the bearing seats 3012 at both ends can reduce the frictional resistance when the rotating shaft 3021 rotates, and also stabilize the positions of the rotating shaft 3021 and the damper panel 302.

The cylinder rod 3041 of the cylinder 304 is provided with a connecting head 305, and the connecting head 305 is connected to the connecting arm 303. In this embodiment, the connecting head 305 is in threaded connection with the cylinder rod 3041, the initial position of the connecting arm 303 connected to the connecting head 305 can be adjusted by adjusting the mounting position of the connecting head 305 on the cylinder rod 3041, and the mounting position of the connecting head 305 is adjusted in a state where the air door plate 302 covers the air suction opening 3011, so that the connecting head 305 and the connecting arm 303 are fixedly connected, and the air door plate 302 can tightly cover the air suction opening 3011 in the initial state, thereby ensuring the sealing performance. In the present embodiment, one end of the connecting arm 303 is connected to the rotating shaft 3021 by a pin, and the other end is connected to the connecting head 305 by a pin.

In addition, the mounting plate 301 is provided with a mounting seat 3013 for fixing the cylinder 304, and the cylinder 304 is rotatably connected to the mounting seat 3013. The extending angle of the cylinder rod 3041 can be adjusted, so that the installation of the cylinder 304 can be better matched with other parts, and the installation efficiency of the air door module 3 is improved.

The working principle or working process of the embodiment is as follows: a plurality of passage openings 201 are formed in the air duct 2 of the lathe bed 1, the passage openings 201 are communicated with the interior of the air duct 2, and an air door module 3 is installed at each passage opening 201. Because the air door plate 302 and the driving component of each air door module 3 are both installed on the installation plate 301, the installation plate 301 is installed on the channel after the air door modules 3 are assembled at other stations except the lathe bed, and the installation of the air door modules 3 is realized. When smoke and dust are required to be removed, the air cylinder 304 is started, the air cylinder rod 3041 drives the connecting arm 303 to swing upwards, the rotating shaft 3021 drives the air door plate 302 to rotate upwards, the air suction port 3011 is opened, and smoke and dust can enter the air duct 2 from the air suction port 3011 to be discharged. Since each damper module 3 is provided with the independent damper plate 302 and the air cylinder 304, the damper plates 302 can be independently opened, and therefore, the number of the damper plates 302 to be opened can be selected as required.

As shown in fig. 4, the suction port 3011 is T-shaped, and the maximum width of the suction port 3011 is equal to the width of the flap 302. When the rotating shaft 3021 drives the air flap panel 302 to rotate, the air flap panel 302 partially extends out from the position where the width of the T-shaped air suction port 3011 is large, so that interference between the air flap panel 302 and the air suction port 3011 is avoided. And in the state that the air door plate 302 covers the air suction port 3011, because the width of the air door plate 302 is equal to the maximum width of the air suction port 3011, the air door plate 302 can closely cover the air suction port 3011.

The remaining features and principles of this embodiment are consistent with embodiment 1.
