[0028] Furthermore, the stirring and cutting mechanism 200 includes an installation frame 201 fixedly installed on the left side of the emulsification tank 100 and a rotating motor 202 installed on the top of the emulsification tank 100, the output end of the rotating motor 202 is connected to the rotating shaft 203 through a coupling transmission, the bottom end of the rotating shaft 203 is fixedly connected to the stirring rod 204, the outer surface of the stirring rod 204 is fixedly installed with a first cutting knife 205, the interior of the installation frame 201 is provided with a power assembly 206, the right side of the power assembly 206 is transmission-connected to a rotating drum 207, and the inner side wall of the rotating drum 207 is fixedly installed with a second cutting knife 208.

[0029] It should be noted that the stirring rod 204, the first cutting knife 205, the rotating drum 207 and the second cutting knife 208 are all arranged in the reaction chamber 101, and the first cutting knife 205 and the second cutting knife 208 are arranged in multiple rows, and each row is provided with multiple ones, each row of the first cutting knife 205 and each row of the second cutting knife 208 are staggered, and the gap between the first cutting knife 205 and the second cutting knife 208 is small.

[0030] In the stirring and cutting mechanism 200, when the rotating motor 202 is started, the stirring rod 204 and the first cutting knife 205 can be driven to rotate in the reaction chamber 101 in the forward direction through the rotating shaft 203, and the rotating drum 207 and the second cutting knife 208 can be driven to rotate in the reaction chamber 101 in the reverse circle through the arranged power component 206, so that under the joint action of the first cutting knife 205 and the second cutting knife 208, the molecular chains of the high-hardness acrylic resin in the solution can be cut and the stirring effect can be achieved, so that the acrylic resin is evenly dispersed in the water phase, thereby improving the emulsification efficiency of the device, reducing energy consumption, and obtaining a high-quality emulsion with uniform particle size.
