[0034] Furthermore: the staff only needs to start the drive motor 1101 to drive the rotating shaft 1103 and the sleeve 1204 to rotate in the opposite direction, so that the stirring rods 2104 located on the upper and lower sides of the preparation kettle 3 rotate in the opposite direction, thereby increasing the stirring efficiency of the stirring rods 2104 on the raw materials in the preparation kettle 3, improving the emulsification efficiency of the raw materials in the preparation kettle 3, and making it easier for the staff to use.

[0035] Example 2

[0036] See Figure 2 、 Figure 6 and Figure 7 , and on the basis of Example 1, it is further obtained that the emulsifying mechanism 2 includes a stirring component 21, a limiting component 22 and an emulsifying component 23, the stirring component 21 is arranged on the outer ring of the driving component 11 and the transmission component 12, the limiting component 22 is arranged at the bottom of the outer ring of the stirring component 21, and the emulsifying component 23 is arranged inside the outer side of the stirring component 21.

[0037] The stirring assembly 21 includes a convex ring 2101, which is fixedly connected to the rotating shaft 1103 and the outer ring of the sleeve 1204. The outer ring of the convex ring 2101 is fixedly connected to the fixed rotating frame 2102. The outer side of the fixed rotating frame 2102 is connected to the fixed shaft 2103 for internal rotation. The outer side of the fixed shaft 2103 is fixedly connected to the stirring rod 2104. The limiting assembly 22 includes a support rod 2201, which is fixedly connected to the convex ring 2101. At the bottom of the outer ring, the outside of the support rod 2201 is fixedly connected with a gasket 2202, and the top of the gasket 2202 is in contact with the bottom of the stirring rod 2104. The emulsifying component 23 includes a feed hole 2301, and the feed hole 2301 is opened inside the outside of the stirring rod 2104. The inner ring of the feed hole 2301 is fixedly connected with a convex strip 2302, and the inner side of the convex strip 2302 is fixedly connected with a convex rod 2303, and the inner side of the convex rod 2303 is fixedly connected with a liquid cylinder 2304.

[0038] Furthermore: during the rotation of the stirring rod 2104, part of the raw liquid comes into contact with the liquid cylinder 2304 and the convex strip 2302 through the material passing hole 2301, and the raw liquid passing through is broken and emulsified by the rapidly rotating convex strip 2302 and the liquid cylinder 2304, thereby increasing the emulsification efficiency of the raw materials. At the same time, when the stirring rod 2104 stops rotating, it will fall downward by itself under the action of gravity, and the stirring rod 2104 is supported by the gasket ring 2202, thereby increasing the distance between the outer end of the stirring rod 2104 and the inner wall of the preparation kettle 3, thereby facilitating the staff to clean the inner wall of the preparation kettle 3.

[0039] During actual operation, when this device is used, when the original liquid in the preparation kettle 3 needs to be emulsified, the staff first starts the drive motor 1101, and the drive motor 1101 starts to drive the rotating shaft 1103 to rotate. At the same time, the rotating shaft 1103 rotates through the cooperation of the gear disc 1 1201, the transmission gear 1202 and the gear disc 2 1203 to drive the sleeve 1204 to rotate synchronously in the opposite direction. The rotation of the rotating shaft 1103 and the sleeve 1204 drives the convex rings 2101 on the upper and lower sides to rotate. The rotation of the convex ring 2101 drives the stirring rod 2104 to rotate through the fixed rotating frame 2102 and the fixed shaft 2103. The stirring rod 2104 rotates and then flips upward vertically under the action of centrifugal force. After that, the stirring rods 2104 on the upper and lower sides rotate in the opposite direction to contact the original liquid in the preparation kettle 3 to complete the emulsification of the original liquid.
