No. two conduits 321 import the inside of No. two soft air-guide pipes 32, and then the importing of solenoid valve 21 through opening is connected to solenoid valve 21
It in air flue 22, then tilts and sprays through spray orifice 23, jet is carried out to the surface of demonstration mechanism 4, to use demonstration mechanism 4
The dust that surface is adhered in journey is cleared up, and the efficiency of dust collection of demonstration mechanism 4 is further increased.
When work, controller can be set on fixed frame 1, controller is electrically connected with motor 11 and solenoid valve 21, is being needed
When using demonstration mechanism 4, is rotated by two motors of controller, 11 main story drive shaft, rotating disc 111 is driven when shaft rotates
Rotation, rotating disc 111 drive auger 6 to rotate, and auger 6 is when the inside of No.1 inner screw sheath 51 and No. two inner screw sheaths 52 rotates
It is contacted with spiral lamination, so that auger 6 is shunk when rotating, sliding bar 2 is driven to move to the direction far from 1 vertical center line of fixed frame
It is dynamic, when sliding bar 2 is mobile, sheet rubber 34 is pushed to bend, at this point, demonstration mechanism 4 is exposed in order to use, mechanism 4 to be demonstrated is complete
When full exposing, motor 11 is closed, when auger 6 is shunk, the air in 61 inner cavity of extruding gasbag imports No.1 air guide through gas-guide tube 62
In hose 31, then the inside through the importing strip air bag 33 of No.1 conduit 311,33 inflation of strip air bag, to demonstration machine
The two sides of structure 4 are protected, and personnel is avoided to collide with the two sides for demonstrating mechanism 4, are avoided demonstration mechanism 4 from damaging, are mentioned
High safety factor controls motor 11 by controller and inverts after demonstrating 4 use of mechanism, at this point, auger 6 rotates backward,
Along the spiral lamination rotation of No.1 inner screw sheath 51 and No. two 52 insides of inner screw sheath, so that auger 6 extends, extruding gasbag 61 passes through
Check valve is pumped into air, and the direction that auger 6 pushes sliding bar 2 to close 1 vertical center line of fixed frame is mobile, meanwhile, controller control
Solenoid valve 21 processed is opened, and the air in strip air bag 33 is successively through 321, No. two soft air-guide pipes 32 of No. two conduits and solenoid valve 21
Discharge, strip air bag 33 restores to the original state, and after two sliding bars 2 contact with each other, controller controls motor 11 and stalls, and controls
Solenoid valve 21 is closed, and after two sliding bars 2 contact, sheet rubber 34 again closes demonstration mechanism 4, effectively reduces dust
The probability being attached in demonstration mechanism 4, the inside for avoiding dust from entering demonstration mechanism 4 cause component short-circuit, extend demonstration machine
The service life of structure 4, it is easy to use.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
