[0027] The stirring motor 5, the funnel 6, the stirring shaft 7, the stirring rod 8 and the fixed tube 100 cooperate with each other, so as to facilitate the breaking up of the agglomerated powdered raw materials and avoid affecting the processing of the subsequent reaction kettle.

[0028] A servo motor 9 is installed on the back of the connecting shell 3, and the front end of the output shaft of the servo motor 9 passes through the connecting shell 3 and extends into the interior thereof. A fixed shaft 10 is installed on the front end of the output shaft of the servo motor 9, and the adjusting column 4 is installed on the surface of the fixed shaft 10. The surface of the adjusting column 4 is in rotational contact with the inner wall of the connecting shell 3. A placement groove 11 is provided on the top and bottom of the adjusting column 4, and a pressure sensor 12 is installed on the inner wall of the placement groove 11. A placement plate 13 is installed on the side where the two pressure sensors 12 are away from each other. A through opening 14 which is interconnected with the placement groove 11 is provided on the top of the connecting shell 3, and a feeding pipe 15 which is interconnected with the fixed shell 2 is installed on the top of the reactor body 1.

[0029] Furthermore, the stirring motor 5, the solenoid valve on the fixed tube 100, the servo motor 9 and the pressure sensor 12 are electrically connected to the controller respectively, and the control circuit can be implemented by simple programming by technicians in this field. This is common knowledge in this field and will not be elaborated here.

[0030] By the mutual cooperation of the connecting shell 3, the adjusting column 4, the servo motor 9, the fixed shaft 10, the placement groove 11, the pressure sensor 12, the placement plate 13, the through port 14 and the feeding tube 15, the effect of quantitative feeding is achieved, avoiding too much or too little raw material being put into the reactor, thereby improving the effect of preparing the modified starch adhesive.

After breaking up, the solenoid valve on the fixed tube 100 is opened by the controller, so that the raw materials in the funnel 6 are discharged into the placement groove 11 at the top through the fixed tube 100 and the through port 14. The weight is sensed by the pressure sensor 12. When the weight reaches the set value, the signal is transmitted to the controller. The controller immediately closes the solenoid valve on the fixed tube 100, and then starts the servo motor 9. The servo motor 9 drives the adjusting column 4 to rotate 180 degrees through the fixed shaft 10, so that the raw materials in the placement groove 11 are put into the interior of the reactor body 1 through the feeding pipe 15, and are processed by the reactor body 1. After the processing is completed, when the raw materials need to be put in again, another placement groove 11 coincides with the position of the through port 14. The solenoid valve on the fixed tube 100 is opened again to discharge the raw materials into the placement groove 11, and the cycle is repeated.
