It is dynamic to drive the slow unlatching of fire door and slowly close, it can both realize that automation is opened the door, ensure that peace that is door opened or closing
Full property and stability.
Brief description of the drawings
Fig. 1 is a kind of structural formula schematic diagram of novel vacuum furnace automatic revolving door of the embodiment of the utility model one；
Fig. 2 is a kind of principle schematic of novel vacuum furnace automatic revolving door of the embodiment of the utility model one.
Embodiment
Fig. 1 and Fig. 2 schematically shows a kind of novel vacuum furnace automatic revolving door of embodiment of the present utility model.
As depicted in figs. 1 and 2, the novel vacuum furnace automatic rotary subcontracts the fire door 1 included on body of heater, fire door cantilever 2, fire door rotation
Axle 3, reducing motor 4 and control system.Control system includes central controller 6, in front of the door grating detector 7 and servo controller 8.
Fire door retaining ring 5 is provided between fire door 1 and body of heater, fire door retaining ring 5 is located at the periphery of fire door 1, fire door retaining ring 5
Fire door 1 and body of heater is set to be tightly connected.Fire door retaining ring is connected with central controller 6 by magnetic valve 51.It is easy to central control
Device 6 processed can control fire door retaining ring 5, add security performance.In use, if fire door retaining ring 5 makes a mistake
Action, fire door retaining ring 5 are opened, and the brake of the reducing motor 4 of fire door 1 can pin fire door rotary shaft 3, prevent stove inner high voltage will
Eject at front door.Reducing motor 4 is connected with fire door rotary shaft 3.The one end of fire door cantilever 2 is fixedly connected with fire door rotary shaft 3.Stove
The other end of door cantilever 2 is fixedly connected with fire door 1.Specifically, the other end of fire door cantilever 2 and the middle part of fire door 1 are fixed
Connection.It is easy to lift at fire door 1.Fire door rotary shaft 3 is connected with reducing motor 4, and reducing motor 4 and servo controller 8 connect.In
