The working principle is as follows: placing the reagents constituting the second mixture into a first barrel 7, placing the reagents constituting the first mixture into a second barrel 10, heating the reagents in the second barrel 10, keeping the temperature constant after the reagents reach a certain temperature, keeping the second barrel 10 in a closed state, and heating the reagents in the first barrel 7 at the temperature in the second barrel 10 and keeping the temperature of the reagents in the first barrel 7 to be basically constant;

the driving motor 1 is started, an output shaft of the driving motor 1 rotates to drive the first column 2 to rotate, the first column 2 rotates to drive the square column 23 to rotate, the square column 23 rotates to enable the first stirring rod 22 to rotate, the first stirring rod 22 rotates to drive the first rotating sleeve 24 to rotate, the sixth gear 49 rotates to drive the fifth gear 50 to rotate, the fifth gear 50 rotates to drive the inner gear 20 to rotate, the inner gear 20 rotates to enable the second stirring rod 25 to rotate, and the first stirring rod 22 and the second stirring rod 25 are enabled to simultaneously keep rotating and stirring in opposite directions, so that the reagent in the second barrel 10 is stirred, the reagent in the second barrel 10 is enabled to be mixed more fully, and the purpose that the reagent is prevented from rotating in one direction in the stirring process is achieved;

synchronously, the first column 2 rotates to drive the third column 15 to rotate, the third column 15 rotates to drive the first rod 14 to rotate, the first rod 14 rotates to drive the second column 12 to orbit, the second column 12 pushes the sliding rod 13 to enable the rack 11 to reciprocate on the top surface of the second barrel 10, the rack 11 moves to drive the third gear 9 to rotate, the third gear 9 rotates to drive the threaded column 16 to rotate, the threaded column 16 rotates to enable the connecting plate 18 to move up/down, further the first stirring rod 22 and the second stirring rod 25 move up/down, and through the up/down movement of the first stirring rod 22 and the second stirring rod 25 in the reagent, different component solute reagents in different layers in the solvent are scattered, the reagents are fully mixed, so that the component reagents can react more fully, and the reaction rate among the component reagents is improved;

synchronously, the connecting plate 18 drives the second lead screw 17 to move up/down in the process of moving up/down, the second lead screw 17 interacts with the second connecting sleeve 29 to enable the second lead screw 17 to rotate, the second lead screw 17 rotates to enable the rotary disc 46 to rotate, when the rotary disc 46 rotates towards a certain direction, the pawl 44 slides over the surface of the ratchet 47, the sector gear 45 does not rotate, when the rotary disc 46 rotates towards the direction opposite to the previous direction, the pawl 44 abuts against the ratchet 47, and the pawl 44 pushes the ratchet 47 to enable the sector gear 45 to rotate;

during the process of stirring the reagent in the second barrel 10, i.e. during the process of forming the first mixture, the sector gear 45 rotates, at this time, the tooth surface side of the sector gear 45 contacts and is meshed with the fourth gear 42 to drive the fourth gear 42 to rotate, the fourth gear 42 drives the fifth column 40 to rotate, the fifth column 40 rotates to drive the third rod 39 to rotate, so that the third rod 39 rotates away from the position right below the connecting column 36, i.e. the third rod 39 does not contact with the connecting column 36 during the up/down movement;

synchronously, the connecting plate 18 drives the first lead screw 3 to move up and down in the process of moving up and down, so that the first connecting sleeve 8 and the first gear 4 rotate, the first gear 4 rotates to drive the second gear 5 to rotate, the second gear 5 rotates to drive the fourth column 31 to rotate, and the fourth column 31 rotates to drive the third stirring rod to rotate, thereby achieving the purpose of stirring the component reagents in the first barrel 7 to uniformly mix the component reagents;

after the first mixture is formed, that is, after a certain time of stirring, the tooth surface side of the sector gear 45 is separated from the fourth gear 42, the sector gear 45 continues to rotate, at this time, the third rod 39 moves to just below the connecting column 36 and stops rotating, along with the up/down movement of the third rod 39, when the third rod 39 moves up, the connecting column 36 is pushed to move up, the spring 33 is compressed, the connecting column 36 pushes the piston 43 to move up, so that the gas in the discharging pipe 34 enters the first barrel 7 through the first conduit 32, the pressure in the first barrel 7 increases in a short time, the gas above the first barrel 7 pushes the second mixture in the first barrel 7 to flow out a certain amount of the second mixture through the second conduit 41, when the third rod 39 is separated from the connecting column 36, the spring 33 is restored to allow the piston 43 to move down, the check valve 28 is opened, a certain amount of gas is introduced into the discharge pipe 34, so that the piston 43 is moved, through the reciprocating motion of the above steps, to achieve the purpose of gradually adding the second mixture into the first mixture in a uniform amount;

through the intermittent type nature contact between sector gear 45 and fourth gear 42 to reach and provide certain time for the formation of first mixture, after first mixture forms, the device can add the purpose of the second mixture of mixing automatically, makes the degree of automation of this device high.

After the spring 33 is restored, the piston 43 is located below the second guide tube 41, and the first stirring rod 22 and the second stirring rod 25 continue to stir during the process of adding the gradually transported amount of the second mixture into the first mixture, so as to achieve the purpose of enabling the first mixture and the second mixture to react more fully.
