Laterally setting, supervisor (9) upside are equipped with multiple interfaces, and multiple interface intervals, which open up, to be set, on multiple interfaces and multiple stavings (7)
Delivery line (8) corresponds, and delivery line (8) lower end is docked and connected with sealing joint, is responsible for that (9) are open at one end to be sealedly connected with electricity
Base (10) is provided with stirring motor on motor cabinet (10), and stirring motor output end is fixedly connected with screw rod (11), screw rod (11)
It is coaxially disposed in supervisor (9) and with supervisor (9), screw rod (11) is cooperatively formed with multiple interface inner ends on the upside of supervisor (9)
For aspirating and squeezing the spinning feeding structure of viscous resin raw material, screw rod (11) front end extends to supervisor (9) other end, supervisor
(9) other end is connected to the feed pipe (3).
8. a kind of method for mixing using high strength composite raw material multistage mixing device a kind of in claim 7, feature
It is: the first order helical screw agitator feeding structure output end S1, is connected to setting with second level blending bunker stirring structure input terminal；
S2, starting first order helical screw agitator feeding structure, realize closing mixing and feeding for the first time；S3, starting second level blending bunker stir
Structure is mixed, realizes second of closing mixing.
9. the method for mixing according to claim 8, it is characterised in that: in step S2: first opening the bucket of staving (1) upper end
Then lid opens solenoid valve (12), slowly injection supervisor (9) is interior under Gravitative Loads for the interior viscous resin raw material of staving (7), simultaneously
Start stirring motor, the rotation in supervisor (9) of screw rod (11) movable set, screw rod (11) will be responsible for (9) interior plurality of raw materials forward
It promotes and carries out first time mixing, be then sent into blending bunker (2) by feed pipe (3) and carry out second of stir mixing, thus real
Now close mixing.
10. the method for mixing according to claim 9, it is characterised in that: in step S3: resin raw material feeding top is stirred
Slot (23) are mixed, in the case where first order helical screw agitator feeding structure is fed forward pressure, resin raw material passes through multiple stirrings from top to bottom
Slot (23) is simultaneously successively stirred by multiple groups stirring blade (22), to realize the second of resin raw material in the closed state sufficiently
It is stirred.
