[0056] A cooling assembly 6 is provided on the top of the cover plate 35. The cooling assembly 6 includes a first auxiliary frame 61 and a second auxiliary frame 62, both of which are fixedly connected to the top of the cover plate 35. Two through slots 63 are provided on the cover plate 35, and the two through slots 63 are respectively located at the bottom of the first auxiliary frame 61 and the second auxiliary frame 62. A second electric push rod 64 is fixedly connected to the front side wall of the U-shaped plate 393. A push plate 65 is fixedly connected to one end of the second electric push rod 64. The top of the second auxiliary frame 62 is fixedly... An air supply duct 66 is connected, which passes through one side wall of the connecting plate 36 and is fixedly connected to the connecting plate 36. After the second electric push rod 64 is working, it can push the push plate 65. Both ends of the push plate 65 are fixedly connected to the sealing blocks 67. The two sealing blocks 67 extend into the first auxiliary frame 61 and the second auxiliary frame 62 respectively. The two sealing blocks 67 are matched with the first auxiliary frame 61 and the second auxiliary frame 62 respectively. A fan 68 is fixedly connected inside the air supply duct 66. The sealing plates can seal the through groove 63.

[0057] An observation window 7 is fixedly connected to the outside of the mixing tank 31. An electric heating plate 8 is fixedly connected to the bottom wall of the inner cavity of the mixing tank 31. A temperature sensor 9 is fixedly connected to the inner wall of the mixing tank 31. The temperature sensor 9 can detect the temperature of the mixture inside the mixing tank 31.

[0058] In actual operation, when using the mixing device, first connect the power supply to the mixing device. After the first electric push rod 398 works, it pushes and pulls the lifting plate 397. The lifting plate 397 drives the rack 381 to move. After the rack 381 moves, it drives the first gear 399 to rotate. After the first gear 399 rotates, it drives the connected connecting rod 32 to rotate. The connecting rod 32 drives the mixing tank 31 to rotate around the connecting rod 32 as the axis, thereby controlling the mixing tank 31 to flip. When the opening of the mixing tank 31 tilts downward, the mixture inside can be poured out.

[0059] After the first motor 396 starts working, it drives the threaded adjusting rod 395 to rotate. After the threaded adjusting rod 395 rotates, it drives the rectangular plate 394 to move up and down. The rectangular plate 394 drives the connecting plate 36 to move up and down. The connecting plate 36 drives the cover plate 35 to move up and down. The cover plate 35 drives the hollow rod 37 to move up and down. In this way, the height of the hollow rod 37 can be adjusted. When the opening of the mixing tank 31 faces upward, the hollow rod 37 can be inserted into the mixing tank 31. After the cover plate 35 is closed on the top opening of the mixing tank 31, the various materials to be mixed are put into the feeding tank 51 respectively. After the materials enter the feeding tank 51, the electronic scale device 4 weighs the materials in the feeding tank 51 to make accurate proportions.

[0060] In this device, the second motor 382 operates and drives the second gear 383 to rotate. The second gear 383 drives the third gear 384 to rotate, and the third gear 384 drives the hollow rod 37 to rotate. The hollow rod 37 drives the stirring blade 38 to rotate, which can stir the material inside the mixing tank 31. When the material in the feeding tank 51 reaches the required volume, the solenoid valve is opened, and the pump body 55 operates to transport the material in the feeding tank 51 to the hollow rod 37. After the material enters the hollow rod 37, it further enters the stirring blade 38 and the bottom plate 39, and passes through the first drainage trough 3. 91 and the second row of liquid tank 392 are discharged, so as to directly spray the material into different areas inside the mixing tank 31. This spraying and feeding, combined with the above steps of rotating and stirring with hollow rod 37, can quickly achieve a uniform mixing effect. During the mixing process, for steps that require heating, the mixture inside the mixing tank 31 can be heated by electric heating plate 8. Temperature sensor 9 can detect the temperature of the mixture for precise temperature control. Observation window 7 allows the staff to observe the color and other changes of the mixture inside, ensuring the accuracy of the stirring work.

[0061] For step 4, which requires cooling the heated mixture, rapid cooling can be achieved using cooling component 6 to avoid the time-consuming process of waiting for it to cool. Specifically, during cooling, the second electric push rod 64 operates and pulls the push plate 65, causing the push plate 65 to move the two sealing blocks 67 to the front of the two through slots 63 to release the sealing effect on the through slots 63. Then, the fan 68 operates and sends airflow through the air supply pipe 66 into the interior of the second auxiliary frame 62, and into the mixing tank 31 through the through slot 63 inside the second auxiliary frame 62. This air-cools the mixture inside the mixing tank 31, and the heat generated during the cooling process is discharged through the through slot 63 below the first auxiliary frame 61, thereby accelerating the cooling process and saving processing time.

[0062] Finally, after the mixture is stirred, the mixing tank 31 is tilted and the mixture inside is discharged through a similar operation as described above. If the inside of the mixing tank 31 needs to be cleaned after processing, the cleaning water can be poured into the feeding tank 51 and the feeding operation can be repeated. The cleaning water is discharged through the first drain trough 391 and the second drain trough 392 to directly rinse the inner wall of the mixing tank 31. During the rinsing process, in order to ensure that different areas of the inner wall of the mixing tank 31 are covered, the hollow rod 37 is raised and lowered. During the raising and lowering process, the first drain trough 391 can evenly rinse the areas at different positions. Compared with the traditional method of directly using water pipes or manual rinsing, this method of direct cleaning is more labor-saving and has a better cleaning effect.

[0063] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
