The positioning ring 401b is fixedly connected to the inner wall of the ventilation slot 3. The mounting assembly 401 is mounted on one side of the mounting bracket 401a.

[0035] This utility model detachably connects the mounting bracket 401a and the positioning ring 401b via a screw 401c, and fixes the positioning ring 401b to the inner wall of the ventilation slot 3. The mounting assembly 401 is installed on one side of the mounting bracket 401a. The mounting bracket 401a can be installed by setting the positioning ring 401b and the screw 401c, and the drive shaft 402 and the motor 404 can be installed by setting the mounting bracket 401a.

[0036] In one embodiment of the safety interlocking protective door for a cigarette factory according to this utility model, such as Figures 1 to 6 As shown, the protective mechanism 5 includes two sealing plates 501 and two sliding grooves 502. The sliding grooves 502 are opened on the inner wall of the ventilation groove 3. The sealing plates 501 are slidably connected to the inside of the sliding grooves 502. The inner wall of the sliding grooves 502 is provided with a through groove 6. A linkage mechanism 7 is provided inside the through groove 6. The through groove 6 and the two sliding grooves 502 are interconnected.

[0037] Specifically, when the smoke sensor 2 issues an alarm, it will activate the linkage mechanism 7. The linkage mechanism 7 will retract inside the through groove 6, thereby causing the sealing plate 501 to slide inside the slide groove 502, exposing the ventilation groove 3 to facilitate smoke exhaust.

[0038] In one embodiment of the safety interlocking protective door for a cigarette factory according to this utility model, such as Figures 3 to 6 As shown, the linkage mechanism 7 includes a linkage plate 701 and an electric push rod 702. One side of each of the two sealing plates 501 is connected to the linkage plate 701. The linkage plate 701 is slidably connected to the inside of the through groove 6. One side of the linkage plate 701 is fixedly connected to the electric push rod 702. The bottom end of the electric push rod 702 is connected to the inner wall of the through groove 6. A power supply mechanism 8 is provided inside the through groove 6.

[0039] Specifically, by using the electric actuator 702 to drive the linkage plate 701 to slide inside the through groove 6, the sealing plate 501 connected to the linkage plate 701 can move synchronously, exposing the ventilation groove 3 and facilitating smoke exhaust.

[0040] In one embodiment of the safety interlocking protective door for a cigarette factory according to this utility model, such as Figures 3 to 6 As shown, the power supply mechanism 8 includes a socket 801, a plug 802 and a spring 803.

The top surface of the plug 802 is set as an arc surface.

[0041] Specifically, when the linkage plate 701 moves, it will squeeze the plug 802 downward and cause the spring 803 to deform. When the linkage plate 701 moves to the maximum position, the plug 802 and the socket 801 engage with each other, thus supplying power to the motor 404 and enabling it to work.

[0042] It should also be noted that the bottom of the socket 801 is connected to a wire, one end of which is fixedly connected to the motor 404. The motor 404 and the electric push rod 702 share the same internal power supply with the door body 1.

[0043] The working principle of this utility model for a safety interlocking protective door in a cigarette factory is as follows: When a fire occurs, a smoke sensor 2 can be installed to detect the fire. The smoke sensor 2 causes the electric push rod 702 to retract. Under the action of the linkage plate 701, the sealing plate 501 can slide in the slide groove 502 until the ventilation groove 3 is exposed. When the linkage plate 701 retracts, it will squeeze the plug 802 downward and cause the spring 803 to deform. When the linkage plate 701 moves to the maximum position, the plug 802 and the socket 801 are engaged with each other, completing the power supply to the motor 404. The motor 404 starts, driving the transmission shaft 402 to rotate, which in turn drives the exhaust fan blade 403 to rotate, thereby performing smoke exhaust operation and reducing the risk of personnel injury.
