[0028] The following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0029] The existing driving device for dough mixers and meat grinders adopts a vertical two-stage planetary gear reduction mechanism. This structural form causes the main unit to be high and bulky, making it inconvenient to store.

[0030] The present application adopts a structural form of a combination of a worm gear reducer and a planetary gear reducer, which reduces the overall height of the drive device and thus reduces the overall height of the main unit, making storage more convenient and increasing the aesthetic effect.

[0031] In order to provide a clearer explanation and description of the technical solution and implementation of the present invention, several preferred specific embodiments for implementing the technical solution of the present invention are introduced below.

[0032] It should be noted that the directional words such as "inside, outside", "front, back" and "left, right" in this article are expressed based on the product usage status. Obviously, the use of the corresponding directional words does not constitute a limitation on the scope of protection of this scheme.

[0033] See Figure 1 、 Figure 2 , Figure 1 This is a schematic diagram of a driving device for a dough and meat mixing machine provided by the present invention. Figure 2 for Figure 1 The diagram shows the assembly diagram of the drive device for dough mixers and meat grinders.

[0034] like Figure 1 、 Figure 2 As shown, the utility model provides a driving device for a dough and meat mixer, including a worm gear reducer 110 and a planetary gear reducer 120. The worm gear reducer 110 is fixed to the reducer housing of the planetary gear reducer 120, and the output worm 111 of the worm gear reducer 110 extends into the planetary gear reducer 120 and is meshed with the input gear 123 of the planetary gear reducer 120.

[0035] like Figure 3 、 Figure 4 As shown, the planetary gear reducer 120 includes a reducer housing 121 and an end cover 122, which are fixed to form an accommodating cavity. The planetary gear mechanism is arranged in the accommodating cavity, including an input gear 123, a sun gear 124, multiple planetary gears 125 and a planet carrier 126.

[0036] The input gear 123 is rotatably mounted on the end cover 122 , and the sun gear 124 is fixedly mounted at the center of the top surface of the input gear 123 .

[0037] A plurality of planetary gears 125 are rotatably mounted on the planetary carrier 126 . A ring gear 127 is disposed on the inner wall of the reducer housing 121 . The planetary gears 125 are meshed with the ring gear 127 and the sun gear 124 for transmission.

[0038] The upper end of the planetary carrier 126 extends through the top surface of the reducer housing 121, forming a first output shaft 128. An axial groove is defined in the top surface of the first output shaft 128. The upper end of the sun gear 124 extends through the planetary carrier 126 and into the axial groove, forming a second output shaft 129. The first output shaft 128 is a low-speed output shaft, used for connecting to a dough kneading tool. The second output shaft 129 is a high-speed output shaft, used for connecting to a meat grinder. Different meat grinders can be used for mincing meat and dicing vegetables. The height of the second output shaft 129 is less than the depth of the axial groove to prevent it from protruding, facilitating the installation of a dough kneading tool.

[0039] See also Figure 1 、 Figure 2 and Figure 4 As shown, the driving device for the dough and meat mixing machine further includes a control board 130, which is fixed to the top surface of the reducer housing 121 by bolts. Thus, the control board 130 is fixed to the driving device as a whole and can be sold together with the driving device, simplifying the assembly process.

[0040] This application also optimizes the structure and fixing method of the reducer housing 121. Figure 3 As shown, the outer circumference of the reducer housing 121 is provided with a plurality of fixing lugs 1211, and the outer circumference of the end cover 122 is provided with fixing seats 1221 corresponding to the fixing lugs 1211. The lugs 1211 and the fixing seats 1221 are fixed by bolts, thereby fixing the end cover 122 to the open end of the reducer housing 121. This structural form reduces the wall thickness of the reducer housing 121 and reduces the overall weight.

[0041] See also Figure 1 、 Figure 3 and Figure 5 A notch 1212 is provided on the fixed ear plate 1211, and a shock-absorbing pad 1213 is clamped in the notch 1212. The shock-absorbing pad 1213 is cylindrical and has an annular groove 1214 in the middle for clamping and fixing the shock-absorbing pad 1213.

[0042] A fixing post 201 is provided on the inner surface of the lower wall of the main housing 20. The fixing post 201 is arranged opposite the notch 1212. The shock-absorbing pad 1213 is fixed to the fixing post 201 via bolts, thereby securing the drive device within the inner cavity of the main housing 20. This fixing structure simplifies the structure and the fixing method, and also reduces vibration through the shock-absorbing pad 1213, thereby reducing noise generated during operation.

[0043] Based on the description of the above specific embodiments, the driving device for a dough mixer and meat grinder provided by the present invention has the following advantages compared with the prior art:

[0044] First, the drive device adopts a combination of a worm gear reducer and a planetary gear reducer, which reduces the overall height of the device and then reduces the overall height of the main unit, making it easier to store and more aesthetically pleasing.

[0045] Second, a notch is provided on the fixed ear plate of the driving device, and a shock-absorbing pad is clamped in the notch. The shock-absorbing pad is fixed to the fixed column to reduce the noise generated during operation.

[0046] Finally, it should be noted that the terms "comprise," "include," or any other variations thereof, as used herein, are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus comprising the element.

[0047] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone should be aware of the structural changes made under the inspiration of the present invention. Any structural changes with the same or similar technical solutions as the present invention fall within the scope of protection of the present invention.
