The DC motor 13 is connected to the mixer 19 via a multi-wedge gear reducer and a planetary reducer. The mixer 19 is suspended inside the mixing tank 1. A safety cover 5 is located at the upper end of the mixing tank 1. The upper cover 10 is connected to the upper end of the upper body, serving as a protective cover for the DC motor 13, the multi-wedge gear reducer, and the planetary reducer. A support rod 16 is connected inside the upper body 14. The limit shaft is connected to the upper body support; the output of the electronic stepless speed controller is connected to the DC motor 13 to form a closed-loop control circuit.

[0004] The multi-wedge gear reducer includes: a main shaft 8, a large multi-wedge wheel 9, a multi-wedge belt 11, and a small multi-wedge wheel 12; the main shaft 8 is mounted on the upper body 14 via bearings, and the large multi-wedge wheel 9 and the central gear 3 of the planetary reducer are connected from top to bottom on the main shaft 8; the small multi-wedge wheel 12 is mounted on the shaft of the DC motor 13, and the multi-wedge belt 11 is wrapped around the large multi-wedge wheel 9 and the small multi-wedge wheel 12 to transmit the kinetic energy of the DC motor 13 to the upper shaft 8.

[0005] The planetary reducer includes: a drive shaft 2, a central gear 3, an eccentric disc 4, a planetary gear ring 6, and planetary gears 7; Planetary gear 7 is located between central gear 3 and planetary ring gear 6. Central gear 3, planetary gear 7 and planetary ring gear 6 mesh with each other. Eccentric disk 4 is connected to the lower end of main shaft 8 of multi-wedge gear reducer through bearings.

Planetary gear 7 is connected to the upper end of drive shaft 2, enabling drive shaft 2 to rotate on its own axis and rotate along planetary ring gear 6. Agitator 19 is connected to the lower end of drive shaft 2.

[0006] For a long time, in actual production, sales, and use, the more specific connection method and structure of the multi-wedge gear reducer are as follows, such as... Figure 5 , Figure 6 , Figure 7 As shown: In the multi-wedge gear reducer, the main shaft 8 is mounted on the upper body 14 via bearings, which are installed inside a bearing sleeve. Bearings are installed at both the upper and lower parts of the bearing sleeve. The main shaft 8 passes through the bearing sleeve via the bearings and is connected to the bearing sleeve. The bearing sleeve has a through hole in the center, and there are multiple steps in the through hole. The steps at both ends have the largest diameter and are used to install bearings. There is a flange at the lower end of the bearing sleeve, and there are multiple mounting holes on the flange. The mounting holes are evenly distributed on two concentric circles with different diameters. It consists of inner and outer ring mounting holes. The outer ring mounting holes are used to fix the planetary gear ring 6 onto the machine plate 14-2 of the upper fuselage 14 cantilever, which includes the motor plate 14-1 and the machine plate 14-2. The inner ring mounting holes fix the flange onto the motor plate 14-1 and the machine plate 14-2 of the upper fuselage 14 cantilever.

There is a protruding protective ring on the edge of the flange, and the planetary gear ring 6 is embedded in the protective ring and tightly connected to the protective ring.

[0007] The upper end of the bearing sleeve of this multi-functional food mixer needs to be fixedly mounted on the motor plate 14-1 and machine plate 14-2 of the upper body 14 cantilever. There also needs to be a protruding protective ring at the edge of the flange. The planetary gear ring 6 is embedded in the protective ring. The planetary gear ring is embedded in the protective ring of the bearing sleeve. They are not installed independently on the cantilever of the upper body. When installing or removing the bearing sleeve and the planetary gear ring, the two components must be installed or removed at the same time. The two interfere with each other, which leads to complex manufacturing and installation processes. Utility Model Content

[0008] The purpose of this invention is to provide a food mixer with a simple manufacturing and installation process, thereby solving the problems of existing food mixers. The manufacturing and installation of mixers has always been a problem due to their complex processes.

[0009] The purpose of this utility model is achieved as follows: it includes a mixing tank, a safety cover, a top cover, a DC motor, an upper body, a hinge shaft, a support rod, a lower body, a mixer, a multi-wedge wheel reducer, a planetary reducer, and an electronic stepless speed regulator; In the multi-wedge gear reducer, the main shaft is mounted on the upper body via bearings, which are installed inside bearing sleeves. The bearing sleeve has a through hole in the center, and stepped holes for installing bearings are located at both ends of the through hole. There is a flange at the lower end of the bearing sleeve, and there are multiple mounting holes on the flange. The mounting holes are evenly distributed in a circle. The flange is installed on the cantilever of the upper body by bolts. The planetary gear ring has a basin-shaped structure. There are internal teeth forming an internal gear ring on the inner circumference of the inner wall of the basin-shaped structure. There are holes on the bottom surface of the basin-shaped structure. The holes include flange holes and mounting holes. The diameter of the flange hole is larger than the outer diameter of the flange. The flange is located at the center of the flange hole. The mounting holes are evenly distributed on the bottom surface of the basin. Bolts are used to directly mount the planetary gear ring onto the cantilever of the upper body.

[0010] The cantilever of the upper fuselage includes a motor plate and a machine plate.

[0011] The flange is bolted to the machine plate of the upper fuselage cantilever.

[0012] The bolts pass through the mounting holes on the planetary gear ring and the holes on the machine plate, directly mounting the planetary gear ring onto the motor plate and machine plate of the upper fuselage cantilever.

[0013] The beneficial effect is that, due to the adoption of the above solution, the bearing sleeve and planetary gear ring used are independently installed on the cantilever of the upper body, and the flange of the bearing sleeve is located in the flange hole in the center of the planetary gear ring. The two do not interfere with each other and can be installed or removed separately.

[0014] There is a bearing step at each end of the central through hole of the bearing sleeve, and the rest are holes of the same diameter. During the processing, only the drill bit needs to be drilled through, without the need for multiple lathe turning operations, which greatly improves the processing efficiency and makes the processing technology extremely simple. The bottom end of the bearing sleeve adopts a small flange, which eliminates the need to machine a protective ring for the planetary gear ring 6 protruding from the edge of the original large flange. This not only simplifies the processing but also saves a lot of non-ferrous metals and reduces manufacturing costs.

[0015] The planetary gear ring has a basin-shaped structure and can be directly installed on the cantilever of the upper body with bolts, making the installation process extremely simple and greatly improving work efficiency.

[0016] This solves the long-standing problem of complex manufacturing and installation processes for existing food mixers.

[0017] Advantages: The bearing sleeves and planetary gear rings used are independently mounted on the cantilever of the machine body. The flange of the bearing sleeve is located in the flange hole in the center of the planetary gear ring. The two do not interfere with each other and can be installed or removed independently, which greatly facilitates the installation or replacement of the bearing sleeves or internal gear rings. The bearing sleeves or internal gear rings have a simple, stronger, and more stable structure, are not easily damaged, and at the same time save non-ferrous metals, optimize the processing technology, and reduce the overall cost of the machine.
