[0019] It should be noted that, during the emulsion polymerization of acrylic emulsion, when powdered materials are added, it is easy for the powdered materials to adhere to the inner wall of the reactor, thereby affecting the reaction efficiency. In this solution, the scraper 33 is attached to and rotated on the inner wall of the reaction barrel 11, so that the scraper 33 can effectively scrape off the materials attached to the inside of the reaction barrel 11, and the stirring mechanism 3 is driven to move vertically as a whole by the up and down movement of the driving rod 24, thereby achieving efficient mixing and stirring of the materials inside the reaction barrel 11.
[0020] Specifically, in the present embodiment, the present scheme mainly comprises a kettle body 1, a driving mechanism 2 is fixedly connected to the top of the kettle body 1, a stirring mechanism 3 is arranged inside the kettle body 1, the driving mechanism 2 and the stirring mechanism 3 are fixedly connected to each other, when the driving rod 24 rotates, the inside of the chute 25 will slide with the outer side of the end of the fixed block 26, so that the chute 25 drives the driving rod 24 to move up and down, when the driving rod 24 rotates, the driving rod 24 will drive the rotating shaft 31 to rotate, because the chute 25 itself will move up and down at the same time when rotating, so that the driving rod 24 drives the stirring mechanism 3 to move up and down while rotating as a whole, when the rotating shaft 31 rotates, the rotating shaft 31 drives the scraper 33 to rotate through two connecting frames 32, at this time, the scraper 33 will slide on the inner wall of the reaction barrel 11, and at the same time, the rotating shaft 31 will also drive multiple stirring rods 34 to rotate, so as to stir the material inside the reaction barrel 11.

[0023] First, start the motor inside the driving device 21 to make the motor drive the driving shaft 22 to rotate. At this time, the driving shaft 22 drives the driving rod 24 to rotate through the limit bar. When the driving rod 24 rotates, the inside of the slide groove 25 will slide with the outer side of the end of the fixed block 26, so that the slide groove 25 drives the driving rod 24 to move up and down.
