Description

Technical Field

[0001] This utility model belongs to the technical field of ultrafine pulverizers, and particularly relates to an ultrafine pulverizer for food. Background Technology

[0002] In the food processing industry, existing food processing crushing equipment often needs to crush large particles or bulky materials into smaller particles or even powder. During the crushing process, existing equipment often fails to effectively crush larger materials, or it repeatedly mixes crushed materials with uncrushed materials, preventing timely separation of the crushed materials and reducing the crushing effect of the uncrushed materials. Furthermore, materials tend to accumulate at the discharge port, hindering effective crushing. Therefore, the overall crushing effect is unsatisfactory.

[0003] Patent CN 218609821 U discloses an ultrafine pulverizer for food use, comprising a spherical cylinder, which includes an outer cylinder and an inner cylinder. The top of the outer cylinder has a feed inlet extending into the inner cylinder, and the bottom of the inner cylinder has a first discharge outlet. A pulverizing mechanism is located inside the inner cylinder, comprising a horizontally arranged rotating shaft and multiple pulverizing rods mounted on the rotating shaft, each pulverizing rod having multiple pulverizing blades. The sidewall of the inner cylinder is a screen, and a gap is left between the outer and inner cylinders to form a storage cavity for storing the pulverized material. The bottom of the outer cylinder has a second discharge outlet. This mechanism can promptly separate and discharge the pulverized material without affecting the continued pulverization of unpulverized material, thereby greatly improving pulverizing efficiency.

[0004] However, this device only achieves food pulverization by rotating several pulverizing rods in the same direction, resulting in relatively low efficiency in food pulverization. Utility Model Content

[0005] The purpose of this invention is to provide an ultrafine pulverizer for food processing to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a food-grade ultrafine pulverizer, comprising a main body, a cavity inside the main body, a cover on the main body, a servo motor on the top of the cover, the output shaft of the servo motor passing through the cover and connected to a drive shaft, a drive gear on the drive shaft, two symmetrical bottom scrapers at the bottom of the drive shaft, and side wall scrapers at the ends of the two bottom scrapers that are far apart from each other, a fixing ring at the bottom of the cover, four driven gears rotatably mounted inside the fixing ring, all four driven gears meshing with the drive gear, a transmission gear ring meshing with the four driven gears on the inner side wall of the fixing ring, a driven shaft connected to the bottom of each of the four driven gears, several pulverizing blades on the driven shaft, a feed inlet and a discharge outlet on the main body, and several support columns evenly distributed along the circumferential direction at the bottom of the main body.

[0007] Preferably, a plurality of the crushing blades are evenly arranged along the axial direction on the driven shaft.

[0008] Preferably, a support ring is arranged at the bottom of both the fixed ring and the driving gear, and the support ring is arranged directly below the four driven gears.

[0009] Preferably, an annular channel is formed between the fixed ring and the support ring at the bottom of the drive gear, allowing the driven shaft to move. A protective ring is slidably arranged in the annular channel, and the protective ring is sleeved on the four driven shafts. A lip seal is provided between the protective ring and the annular channel.

[0010] Preferably, each of the four driven gears has a connecting shaft at its top, and the same limiting ring is connected to each of the four connecting shafts. All four connecting shafts are rotatably mounted on the limiting ring.

[0011] Preferably, the bottom scraper is in close contact with the bottom inner wall of the cavity.

[0012] Preferably, the sidewall scraper is in close contact with the sidewall of the cavity.

[0013] The beneficial effects of this utility model are: In this invention, the presence of a drive gear and driven gears allows food to be fed into the cavity through the inlet. A servo motor drives the drive shaft to rotate, which in turn rotates the drive gear, causing four driven gears to rotate. Due to the constraint of the transmission gear ring, the four driven gears rotate along the drive gear while rotating on their own axis, thus causing the driven shaft to rotate along the drive shaft while rotating on its own axis. This achieves the goal of omnidirectional pulverization of food within the cavity by multiple pulverizing blades, improving work efficiency. Furthermore, the bottom scraper and side wall scraper at the bottom of the drive shaft can remove food debris adhering to the bottom inner wall and side walls of the cavity, facilitating subsequent cleaning of the cavity interior.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-4A food-grade ultrafine pulverizer includes a main body 1, a cavity 18 inside the main body 1, a cover 3 on the main body 1, a servo motor 4 on the top of the cover 3, the output shaft of the servo motor 4 passing through the cover 3 and connected to a drive shaft 7, a drive gear 16 on the drive shaft 7, two symmetrical bottom scrapers 9 at the bottom of the drive shaft 7, and side wall scrapers 11 at the ends of the two bottom scrapers 9 that are far apart from each other, a fixing ring 12 at the bottom of the cover 3, four driven gears 19 rotatably mounted inside the fixing ring 12, all four driven gears 19 meshing with the drive gear 16, a transmission gear ring 13 meshing with the four driven gears 19 on the inner side wall of the fixing ring 12, a driven shaft 8 connected to the bottom of each of the four driven gears 19, several pulverizing blades 10 on the driven shaft 8, a feed inlet 5 and a discharge outlet 6 on the main body 1, and several support columns 2 evenly distributed along the circumference at the bottom of the main body 1.

[0018] With the provided drive gear 16 and driven gear 19, food can be fed into the cavity 18 from the feed inlet 5 during use. At this time, the servo motor 4 drives the drive shaft 7 to rotate. When the drive shaft 7 rotates, the drive gear 16 rotates, which in turn drives the four driven gears 19 to rotate. Due to the restriction of the transmission gear ring 13, the four driven gears 19 rotate along the drive gear 16 while rotating on their own axis. This causes the driven shaft 8 to rotate along the drive shaft 7 while rotating on its own axis. This achieves the purpose of pulverizing the food in the cavity 18 from all directions by multiple pulverizing blades 10, improving work efficiency. The bottom scraper 9 and side wall scraper 11 at the bottom of the drive shaft 7 can scrape off the food debris attached to the bottom inner wall and side wall of the cavity 18, making it convenient for subsequent cleaning of the cavity 18.

[0019] Specifically, in this embodiment, a plurality of crushing blades 10 are evenly arranged along the axial direction on the driven shaft 8.

[0020] Specifically, in this embodiment, a support ring 17 is arranged at the bottom of both the fixed ring 12 and the driving gear 16. The support ring 17 is arranged directly below the four driven gears 19. An annular channel is formed between the fixed ring 12 and the support ring at the bottom of the driving gear 16, allowing the driven shaft 8 to move. A protective ring 20 is slidably arranged in the annular channel. The protective ring 20 is sleeved on the four driven shafts 8. A lip seal is provided between the protective ring 20 and the annular channel.

[0021] The support ring 17 can support the driven gear 19, and the annular channel formed between the support rings 17 can guide the movement direction of the driven shaft 8. The protective ring 20 and the lip seal between the protective ring 20 and the annular channel can effectively prevent material debris from entering between the driving gear 16 and the driven gear 19, thus effectively avoiding debris affecting the transmission between the gears.

[0022] Specifically, in this embodiment, each of the four driven gears 19 has a connecting shaft 15 arranged on its top, and the same limiting ring 14 is connected to each of the four connecting shafts 15. The four connecting shafts 15 are rotatably mounted on the limiting ring 14.

[0023] By setting the limiting ring 14, the distance between the four driven gears 19 can be limited, preventing the crushing blades 10 on the four driven shafts 8 from colliding with each other.

[0024] Specifically, in this embodiment, the bottom scraper 9 is closely attached to the bottom inner wall of the cavity 18, which facilitates the scraping of food debris attached to the bottom inner wall of the cavity 18.

[0025] Specifically, in this embodiment, the side wall scraper 11 is closely attached to the side wall of the cavity 18, which facilitates the scraping of food debris attached to the side wall of the cavity 18.

[0026] It should be noted that the servo motor and the electrical components mentioned in this article are electrically connected to the external main controller and the mains power. Furthermore, the selection of the servo motor and the standard parts mentioned in this article are common knowledge in the field and will not be elaborated upon here.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
