Summary of the invention:
Purpose of the present invention is exactly the deficiency that exists for prior art and provide a kind of and can automatically open and close air door, control easily automatic air door of baking oven.
To achieve these goals, the technical solution used in the present invention is: automatic air door of baking oven, include the air door that is arranged on the air channel exhaust ports, air door is connected with the air channel by automatic switch device, automatic switch device includes the holder that is fixed on the air channel, be rotatably connected on the rotating shaft on the air channel, be socketed in the runner of rotating shaft one end, motor, by motor-driven screw mandrel, be slidingly connected at the slide block on the holder, flexible member, one end of air door is socketed in the rotating shaft other end, the other end of air door is unsettled, screw mandrel is rotatably connected on the holder, slide block and wire rod thread are flexibly connected, one end of flexible member is connected on the slide block, and its other end is connected to submarginal position on the runner; Air door relies on deadweight to open in opening procedure, air door is closed by the automatic switch device driving in closing process, when air door is in closed condition, turn to the closest approach of relative slide block on the runner with the junction of flexible member, make air door self-locking under the effect of flexible member.
Described flexible member is spring or elastic webbing.
The screw that has been threaded respectively on described slide block and the runner, the two ends of flexible member are connected with the screw that slide block is connected with runner respectively.
Described runner is provided with a plurality of screws that are positioned at diverse location.
Described motor drives connection wire rod by shaft coupling.
Beneficial effect of the present invention is: automatic air door of baking oven provided by the invention, include air door, air door is connected with the air channel by automatic switch device, automatic switch device includes holder, rotating shaft, runner, motor, screw mandrel, slide block, flexible member, one end of air door is socketed in the rotating shaft other end, the other end of air door is unsettled, screw mandrel is rotatably connected on the holder, one end of flexible member is connected on the slide block, and its other end is connected to submarginal position on the runner, when the excess Temperature before the catalysis in the air channel, motor does not rotate, air door can rely on deadweight to open, and when the temperature before the catalysis in the air channel was in OK range, electric machine rotation slided by screw mandrel band movable slider and strains flexible member, runner slowly rotates under the effect of flexible member, drive air door and rotate exhaust close, can automatically open and close air door, and open and close by flexible member control air door, so that air door slowly rotates, control is accurately convenient, and high efficiency reduces labour intensity.
Description of drawings:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of automatic switch device of the present invention.
Embodiment:
The present invention is further illustrated below in conjunction with accompanying drawing, see shown in Fig. 1,2, automatic air door of baking oven of the present invention includes the air door 1 that is arranged on 3 exhaust outlets, 2 places, air channel, air door 1 is connected with air channel 3 by automatic switch device 4, automatic switch device 4 includes the holder 41 that is fixed on the air channel 3, is rotatably connected on the rotating shaft 42 on the air channel 3, the runner 43 that is socketed in rotating shaft 42 1 ends, motor 44, by the screw mandrel 45 of motor 44 drivings, be slidingly connected at slide block 46, flexible member 47 on the holder 41.Motor 44 is by PLC control running, motor 44 drives connection wire rod 45 by shaft coupling 49, one end of air door 1 is socketed in rotating shaft 42 other ends, the other end of air door 1 is unsettled, screw mandrel 45 is rotatably connected on the holder 41, slide block 46 is flexibly connected with screw mandrel 45 screw threads, one end of flexible member 47 is connected on the slide block 46, its other end is connected to submarginal position on the runner 43, when air door 1 is in closed condition, turn to the closest approach of relative slide block 46 on the runner 43 with the junction of flexible member 47, when motor 44 did not rotate, runner 43 can be owing to the deadweight of air door 1 is rotated under the effect of flexible member 47, so that air door 1 can self-locking under in off position, in the time of need to opening, only need motor 44 to rotate, runner 43 can rely on because of the effect of the element 47 that follows the string the deadweight rotating opening of air door 1.
