[0025] Wherein, support mechanism 10 is used to support stirring mixing mechanism 20, and stirring mixing mechanism 20 can play a good protection effect to motor 231 when stirring starts.

[0026] Please refer to Figure 1 And Figure 2 Stirring mixing mechanism 20 includes barrel 210, top cover plate 220, rotating drive assembly 230, threaded transmission rod 240 and stirring blade piece 250.Barrel 210 is installed in the inside of support mechanism 10, top cover plate 220 is fixed at the top of barrel 210, and top cover plate 220 is provided with filling port, one side of barrel 210 is provided with discharge pipe 260, and discharge pipe 260 is provided with first valve 270.Threaded transmission rod 240 rotates and penetrates top cover plate 220, stirring blade piece 250 is located below top cover plate 220 and is screw connected with threaded transmission rod 240, and rotating drive assembly 230 is installed above support mechanism 10 to drive threaded transmission rod 240 to rotate.

[0027] The emulsion and ingredients such as shell powder are added from the top of the top cover plate 220 to the inside of the barrel 210. Before the emulsion and ingredients are added, the stirring blade 250 is located near the top cover plate 220, and the added emulsion and ingredients are located below the stirring blade 250. The rotating drive assembly 230 drives the threaded drive rod 240 to rotate, and the rotating threaded drive rod 240 drives the stirring blade 250 to move from top to bottom. When the stirring blade 250 moves to below the liquid surface, the stirring blade 250 is subjected to increased resistance from the emulsion, which provides good protection for the motor 231 in the rotating drive assembly 230. Until the stirring blade 250 moves to the bottom end of the threaded drive rod 240, the emulsion can be stably stirred and dispersed in the barrel 210. After the use of the equipment is completed and the emulsion is discharged through the discharge pipe 260, the rotating drive assembly 230 drives the threaded drive rod 240 to rotate in the opposite direction, and the stirring blade 250 is driven to move upward to the position near the top cover plate 220 to complete the reset before the emulsion and ingredients are added again.

[0028] Further, please refer to Figure 1 , the support mechanism 10 includes an outer frame 110 and a mounting bracket 120, the outer frame 110 is provided with support legs 130 at the bottom, and the mounting bracket 120 is arranged above the outer frame 110.

[0030] In the specific arrangement, please refer to Figure 2 , the barrel 210 is provided with an overflow pipe 280 outside, and the second valve 290 is installed on the overflow pipe 280. When the emulsion is added from the feeding port, the valve above the overflow pipe 280 is opened to prevent the emulsion from overflowing the stirring blade 250. After the emulsion is added, the second valve 290 is closed to prevent the emulsion from flowing out of the overflow pipe 280 during stirring and dispersion.

[0031] In the above specific embodiment, please refer to Figure 3 , the rotating drive assembly 230 includes a motor 231, a transmission shaft 232, a belt transmission part 233, and a gear transmission part 234. The transmission shaft 232 is rotatably arranged on the support mechanism 10, the belt transmission part 233 is connected to the transmission shaft 232 and the motor 231, and the gear transmission part 234 is connected to the transmission shaft 232 and the threaded drive rod 240.

[0032] The motor 231 drives the transmission shaft 232 to rotate through the belt transmission part 233, and the rotating transmission shaft 232 drives the threaded transmission rod 240 to rotate through the gear transmission part 234.

[0033] Further, the belt transmission part 233 comprises a driving pulley, a driven pulley and a transmission belt, the driving pulley is fixedly sleeved on the output shaft end of the motor 231, the belt transmission part 233 is fixedly sleeved on the outside of the transmission shaft 232, and the connecting belt connects the driving pulley and the driven pulley. The motor 231 drives the driving pulley to rotate, and drives the transmission shaft 232 to rotate through the cooperation of the driven pulley and the transmission belt.

[0034] Specifically, the gear transmission part 234 comprises a first bevel gear and a second bevel gear, the first bevel gear is fixedly sleeved on the end of the transmission shaft 232, the second bevel gear is fixedly sleeved on the top end of the threaded transmission rod 240, and the first bevel gear and the second bevel gear are engaged.

[0035] In the specific setting, please refer to Figure 4 The stirring blade member 250 comprises a sleeve 251, a leaf plate 252 and a back frame 253. The sleeve 251 is screwed and sleeved on the outside of the threaded transmission rod 240, the leaf plate 252 is obliquely arranged on the outside of the sleeve 251, and the back frame 253 is arranged on the back of the leaf plate 252 to connect and fix the leaf plate 252.

[0036] It should be noted that the specific model and specification of the motor 231 need to be selected and determined according to the actual specification of the device, and the specific selection and calculation method adopts the existing technology in the art, so it will not be described in detail. The power supply and principle of the motor 231 are clear to those skilled in the art, and will not be described in detail here.

[0037] The working principle of the acrylic emulsion dispersion device is as follows: when in use, the emulsion and ingredients such as shell powder are added into the barrel 210 from the charging port at the top of the top cover plate 220. Before the emulsion and ingredients are added, the stirring blade 250 is located close to the top cover plate 220, and the added emulsion and ingredients are located below the stirring blade 250. The rotating drive assembly 230 drives the threaded transmission rod 240 to rotate, and the rotating threaded transmission rod 240 drives the stirring blade 250 to move from top to bottom. When the stirring blade 250 moves to below the liquid surface at a higher position, the resistance of the stirring blade 250 to the emulsion is increased, which has a good protection effect on the motor 231 in the rotating drive assembly 230. Until the stirring blade 250 moves to the bottom end of the threaded transmission rod 240, the emulsion and ingredients can be stably stirred and dispersed in the barrel 210. After the use of the equipment is completed and the emulsion and ingredients are added again, the rotating drive assembly 230 drives the threaded transmission rod 240 to rotate reversely, and drives the stirring blade 250 to move upward to the position close to the top cover plate 220 to complete the reset.

[0038] The preferred embodiments of the present application are described above, but the present application is not limited to the above. Any modifications, equivalent replacements, improvements, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
