Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and in particular to a premixing device for raw materials used in salad dressing production. Background Technology

[0002] Salad dressing is made with a large amount of eggs and oil. This type of sauce has a long history in the diet, and its consumption continues to increase, indicating a large market prospect. Depending on the taste, ingredients such as butter, bananas, and potatoes can be added to salad dressing to create different flavors. When making flavored salad dressings, a premixing device is required to mix the raw materials in advance and then emulsify them.

[0003] Existing premixing devices, such as the one disclosed in patent CN221230362U, typically have one or more stirring blades to mix the materials. The mixing effect is poor, the shear force on the raw materials is small, and lumpy raw materials cannot be quickly broken up. Moreover, during the mixing process, the raw materials tend to adhere to the inner wall of the mixing tank, which cannot be fully mixed. They cannot be discharged during the discharge process, resulting in waste and difficulty in cleaning.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

The end of the scraper facing the central stirring shaft has several spaced notches that mate with the side stirring blades. The end of the scraper facing away from the central stirring shaft is used to contact the inner wall of the mixing tank.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0020] Please see Figures 1 to 4This application provides a raw material premixing device for salad dressing production, including a frame 1 and a mixing tank 2 mounted on the frame 1. The top of the mixing tank 2 is open. A lifting device 3 is mounted on the frame 1, and a lifting frame 4 is mounted on the output end of the lifting device 3. The lifting device 3 is a cylinder, and two lifting devices 3 are configured. The two lifting devices 3 work synchronously to drive the lifting frame 4 to move linearly above the mixing tank 2. A drive motor 5 is fixedly mounted on the lifting frame 4, and a central stirring shaft 6 and a rotating disk 7 are rotatably mounted on the lifting frame 4. The rotating disk 7 is rotatably mounted on the lifting frame 4 through a rotating disk bearing. The output end of the drive motor 5 is connected to the central stirring shaft 6 through a coupling, thereby driving the central stirring shaft 6 to rotate. Multiple central stirring blades 8 are mounted on the central stirring shaft 6 along its axial direction. The central stirring blades 8 stir the material at the center of the mixing tank 2. A side stirring shaft 9 is rotatably mounted on the rotating disk 7, and multiple side stirring blades 10 are mounted on the side stirring shaft 9 along its axial direction. The rotating disc 7 rotates 10 times while simultaneously rotating on its own axis to agitate the material at the edge of the mixing tank 2. The side stirring blades 10 and the central stirring blades 8 are staggered, allowing them to work together to shear the raw materials, facilitating the crushing of lumpy materials and improving the mixing effect. A scraper 11 is fixedly installed at the lower end of the rotating disc 7, and the rotating disc 7 is fixedly connected to the scraper 11 via a connecting frame 25. The end of the scraper 11 facing the central stirring shaft 6 has several spaced notches 12, which are designed to cooperate with the side stirring blades 10. When the side stirring blades 10 rotate, their edges pass through the notches 12, which can shear the raw materials, facilitating the crushing of lumpy materials and improving the mixing effect. The end of the scraper 11 facing away from the central stirring shaft 6 is used to contact and cooperate with the inner wall of the mixing tank 2, thereby scraping off the material adhering to the inner wall of the mixing tank 2. The central stirring shaft 6 is connected to the side stirring shaft 9 via a gear transmission assembly, and the central stirring shaft 6 is connected to the rotating disc 7 via a reduction transmission assembly.

[0021] Among them, at least two side stirring shafts 9 are provided, and the side stirring shafts 9 are distributed in a circle around the central stirring shaft 6.

[0022] The gear transmission assembly includes a central cylindrical gear 13 and a side cylindrical gear 14. The central cylindrical gear 13 is fixedly mounted on the central stirring shaft 6, and the side cylindrical gear 14 is fixedly mounted on the side stirring shaft 9. The central cylindrical gear 13 and the side cylindrical gear 14 are meshed together. The central stirring shaft 6 drives the central cylindrical gear 13 to rotate, and the central cylindrical gear 13 drives the side cylindrical gear 14 and the side stirring shaft 9 to rotate.

[0023] The reduction transmission assembly includes a first cylindrical gear 15, a second cylindrical gear 16, a worm 17, a worm wheel 18, a first transmission shaft 19, a second transmission shaft 20, a first bevel gear 21, a second bevel gear 22, a third cylindrical gear 23, and an external gear ring 24. The worm 17, the first transmission shaft 19, and the second transmission shaft 20 are all rotatably mounted on the lifting frame 4. The first cylindrical gear 15 is fixedly mounted on the central stirring shaft 6, the second cylindrical gear 16 is fixedly mounted on the worm 17, the worm wheel 18 and the first bevel gear 21 are fixedly mounted on the first transmission shaft 19, and the worm 17 is meshed with the worm wheel 18. The second bevel gear 22 and the third cylindrical gear 23 are fixedly mounted on the second transmission shaft 20, and the first bevel gear 21 is meshed with the second bevel gear 22. The external gear ring 24 is fixedly mounted on the rotating disk 7 and is coaxially arranged with the central stirring shaft 6. The third cylindrical gear 23 is meshed with the external gear ring 24. The central stirring shaft 6 drives the first cylindrical gear 15 to rotate, which in turn drives the second cylindrical gear 16 and the worm gear 17 to rotate. The worm gear 17 drives the worm wheel 18, the first transmission shaft 19, and the first bevel gear 21 to rotate. The first bevel gear 21 drives the second bevel gear 22, the second transmission shaft 20, and the third cylindrical gear 23 to rotate. The third cylindrical gear 23 drives the external gear ring 24 and the rotating disk 7 to rotate. By setting up a speed reduction transmission assembly, a speed reduction transmission effect can be achieved, allowing the central stirring shaft 6 to drive the rotating disk 7 to rotate slowly, reducing the wear of the scraper 11 and facilitating stable scraping of materials by the scraper 11.

[0024] The bottom of the mixing tank 2 is provided with a discharge port 26, and a discharge valve 27 is installed on the discharge port 26. By opening the discharge valve 27, the material in the mixing tank 2 can be discharged from the discharge port 26.

[0025] The central stirring shaft 6, worm gear 17, first drive shaft 19, and second drive shaft 20 are all rotatably mounted on the lifting frame 4 via bearings, while the side stirring shaft 9 is rotatably mounted on the rotating disk 7 via bearings.

[0026] A circular baffle 28 is fixed on the connecting frame 25, through which the central stirring shaft 6 and the side stirring shaft 9 pass. The circular baffle 28 has openings for the central stirring shaft 6 and the side stirring shaft 9 to pass through. The circular baffle 28 forms a physical isolation between the central cylindrical gear 13 and the side cylindrical gear 14, which can effectively prevent materials from entering the gear gap between the central cylindrical gear 13 and the side cylindrical gear 14, thus avoiding affecting the transmission.

[0027] The working principle of this embodiment:

[0028] First, such as Figure 1 As shown, the lifting device 3 drives the lifting frame 4 to rise to the highest point, so that the open end of the top of the mixing tank 2 is exposed, making it easier to put raw materials into the mixing tank 2.

[0029] After the raw materials have been added, such as Figure 4As shown, the lifting device 3 drives the lifting frame 4 to rise to the lowest point, so that the lifting frame 4 covers the mixing tank 2;

[0030] Then, the drive motor 5 is started, which drives the central stirring shaft 6 to rotate. The central stirring shaft 6 drives the side stirring shaft 9 to rotate through the gear transmission assembly, and drives the rotating disk 7 to rotate through the reduction transmission assembly. The rotating disk 7 drives the side stirring shaft 9 to rotate. When the side stirring blade 10 passes through the notch 12, it will shear and crush the raw material at the notch 12. The raw material will also be sheared and crushed when it is between the side stirring blade 10 and the central stirring blade 8, thereby improving the material mixing effect.

[0031] The rotating disk 7 drives the scraper 11 to rotate slowly. The scraper 11 scrapes off the material adhering to the inner wall of the mixing tank 2, thereby making the material fully mixed and improving the mixing effect.

[0032] Finally, after mixing is complete, open the discharge valve 27 to discharge the material in the mixing tank 2 through the discharge port 26.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
