Description

Technical Field

[0001] This utility model relates to the field of food grinding technology, specifically to a production component of a grinding device for food processing. Background Technology

[0002] Through repeated impact, compression and friction between the grinding media and the material, a powder with uniform and extremely fine particle size is achieved; Application scenarios: suitable for foods that require extremely fine powder, such as high-end condiments (sesame paste, peanut butter), nutritional supplements (ultrafine protein powder), and special diets (such as residue-free baby food);

[0003] Grinding equipment generally includes a drive mechanism, with a grinding roller fixed at the top of the drive mechanism. There is a certain gap between the outer side of the roller and the grinding sleeve inside the tank. When the grinding roller rotates, it will precisely process the food located in the gap.

[0004] However, the grinding rollers in existing grinding equipment are generally single-roller structures with a fixed rotation direction and limited contact area with the material. This results in a small amount of material participating in grinding per unit time, with some particles being over-crushed and others not being fully ground, leading to relatively low overall grinding efficiency. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing grinding equipment mostly adopts a single-roller structure with a fixed direction, resulting in a limited contact area with the material, a small grinding volume per unit time, uneven particle crushing, over-grinding and under-grinding, and low overall grinding efficiency.

[0006] To solve the above problems, the technical solution adopted by this utility model is a production component of a grinding device for food processing, including a tank body, a grinding structure inside the tank body, the grinding structure including a planetary gear transmission mechanism, grinding rollers with opposite directions fixed above and below the planetary gear transmission mechanism, a grinding sleeve inside the tank body, a drive mechanism located at the bottom of the planetary gear transmission mechanism, and a tank cover hinged to the top of the tank body.

[0007] The planetary gear transmission mechanism includes a drive shaft, a pair of gears 1 fixed to one side of the drive shaft, and connecting frames rotatably provided above and below the pair of gears 1 on the side of the drive shaft. Several gears 2 meshing with gears 1 are rotatably provided on the outer edge of the connecting frames. An outer wheel is provided on the outer side of the gears 2, and an inner gear meshing with gears 2 is provided on the inner side of the outer wheel. The rotation direction of the outer wheel is opposite to the rotation direction of the drive shaft.

[0008] The upper grinding roller is fixed to the outer wheel with screws, and the drive shaft is fixed to the lower grinding roller with screws.

[0009] As a further embodiment of this utility model: the outer side of the grinding sleeve is provided with several slots, and the inner side of the tank is fixed with several locking platforms that cooperate with the slots, so that the grinding sleeve can be easily disassembled and replaced with grinding sleeves of different inner diameters to achieve different grinding precisions.

[0010] As a further embodiment of this utility model: the drive mechanism includes a motor fixed at the bottom end of the transmission shaft for driving the transmission shaft to rotate, and the bottom end of the tank is located on the base plate supported by the power supply motor.

[0011] As a further embodiment of this utility model: a conical baffle is fixed on the inner side of the tank above the motor, which can guide the ground material. A discharge port is opened on the side of the tank above the conical baffle for outputting the ground material. An inlet is opened on the upper side of the tank cover for pouring in unprocessed material.

[0012] As a further embodiment of this utility model: a stop post is fixed on the upper side of the can lid near the edge, and a fastening handle is hinged to the side of the can body. A buckle is rotatably provided on the side of the fastening handle, and one end of the buckle is fastened to the outside of the stop post. By fastening the buckle to the outside of the stop post, the position of the can lid can be fixed.

[0013] As a further embodiment of this invention, the outer sides of the two grinding rollers are provided with grinding grooves with opposite patterns to increase friction and thus improve grinding efficiency.

[0014] Compared with the prior art, the advantages of this utility model are: this application adds a planetary gear transmission mechanism and also provides a pair of grinding rollers. The planetary gear transmission mechanism can drive the pair of grinding rollers to rotate in different directions, preventing the grinding direction from being too uniform and increasing the grinding efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0024] Combined with appendix Figure 2-3 It can be seen that the tank includes a tank body 1, which has a grinding structure inside. The grinding structure includes a planetary gear transmission mechanism. A conical baffle 13 is fixed on the inner side of the tank body 1 above the motor 12 to guide the ground material. A discharge port 1.1 is opened on the side of the tank body 1 above the conical baffle 13 for discharging the ground material. An inlet 4.1 is opened on the upper side of the tank cover 4 for pouring in unprocessed material. The top of the tank body 1 is hinged to the tank cover 4. A baffle post 14 is fixed on the upper side of the tank cover 4 near the edge. A fastening handle 15 is hinged to the side of the tank body 1. A buckle 16 is rotatably provided on the side of the fastening handle 15. One end of the buckle 16 is fastened to the outside of the baffle post 14. By fastening the buckle 16 to the outside of the baffle post 14, the position of the tank cover 4 can be fixed.

[0025] Combined with appendix Figure 3 , 4It can be seen that grinding rollers 2 with opposite directions are fixed above and below the planetary gear transmission mechanism. The upper grinding roller 2 is fixed to the outer wheel 9 by screws, and the transmission shaft 5 is fixed to the lower grinding roller 2 by screws. The two grinding rollers 2 have grinding grooves with opposite patterns on their outer sides to increase friction and improve grinding efficiency. A grinding sleeve 3 is provided inside the tank body 1. Several slots 3.1 are provided on the outer side of the grinding sleeve 3. Several locking platforms 11 that cooperate with the slots 3.1 are fixed inside the tank body 1 to facilitate the disassembly of the grinding sleeve 3 and to replace grinding sleeves 3 with different inner diameters to achieve different grinding precisions. A drive mechanism is provided at the bottom of the planetary gear transmission mechanism. The drive mechanism includes a motor 12 fixed at the bottom of the transmission shaft 5 to drive the transmission shaft 5 to rotate. The bottom of the tank body 1 is located on the base plate supported by the motor 12.

[0026] Combined with appendix Figure 1 It can be seen that the planetary gear transmission mechanism includes a transmission shaft 5. A pair of gears 6 are fixed on one side of the transmission shaft 5. A connecting frame 7 is rotatably provided on the side of the transmission shaft 5 above and below the pair of gears 6. Several gears 8 that mesh with gears 6 are rotatably provided on the outer edge of the connecting frame 7. An outer wheel 9 is provided on the outer side of gear 8. An inner gear 10 that meshes with gear 8 is provided on the inner side of the outer wheel 9. The rotation direction of the outer wheel 9 is opposite to the rotation direction of the transmission shaft 5.

[0027] The working principle of this application is as follows: When the transmission shaft 5 rotates, it will drive two gears 6 to rotate, but will not drive the connecting frame 7 to rotate. When gear 6 rotates, it will drive gear 8 to rotate in the opposite direction. The rotation of gear 8 will drive the internal gear 10 that meshes with it to rotate. Since it is internal meshing, the rotation direction of the internal gear 10 is the same as that of gear 8. Therefore, the rotation direction of the transmission shaft 5 is opposite to the rotation direction of the outer wheel 9. The two grinding rollers 2 are fixed to the outer wheel 9 and the transmission shaft 5 respectively, so the rotation directions of the two grinding rollers 2 are opposite.

[0028] When grinding food, the raw materials are poured into the tank 1, and the food is crushed by the grinding roller 2 and the grinding sleeve 3, and finally output from the outlet 1.1.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
