Embodiments of the invention

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in FIG. 1 and FIG. 2, a cutter assembly 1 according to an embodiment of the present invention includes a cutter shaft assembly and a blade 12 mounted on the cutter shaft assembly. The cutter shaft assembly includes a hollow cutter shaft 111 and The drive ring 112; the cutter shaft 111 is connected to the blade 12 on the radial outer side, the blade 12 is connected to the drive ring 112, and the drive ring 112 is connected to the transmission mechanism 13. The blade 12 may be integrally formed with the cutter shaft 111 and the drive ring 112, or may be a combination of detachable assemblies. When the detachable assembly is combined, the size of the blade 12 may be set according to actual conditions. The shape and, in a detachable combination, facilitate the cleaning and replacement of the blade 12. The transmission mechanism 13 drives the drive ring 112 to rotate the blade 12 under the guidance of the cutter shaft 111. The transmission mechanism 13 can be a friction wheel mechanism or a gear transmission mechanism. The cutter assembly 1 provided by the invention is driven by the transmission mechanism 31 from the side of the drive ring 112 to drive the blade 12 to rotate, so that not only the transmission is stable, but also the corresponding functions can be reliably realized (such as stirring food, etc.), and from the side The drive is compact and reduces the space for layout of each mechanism. The layout is convenient and the space is small, which is in line with the trend of miniaturization of product volume.

Specifically, as shown in FIGS. 1 and 2, the drive ring 112 is disposed at an axial upper portion or an axial lower portion of the cutter shaft 111, and can be selected according to a specific application. When the driving ring 112 is disposed at the upper axial portion of the arbor 111, the transmission mechanism 13 coupled thereto is also disposed at the upper portion. Similarly, when the driving ring 112 is disposed at the axial lower portion of the arbor 111, it is coupled thereto. The transmission mechanism 31 is also correspondingly disposed at the lower portion.

Specifically, as shown in FIGS. 1 and 2, the drive ring 112 is provided with internal or external teeth that cooperate with the transmission mechanism 13. According to the specific layout manner of the transmission mechanism 13, whether the outer ring or the inner tooth is disposed on the driving ring 112 is selected. If the transmission mechanism 13 is disposed inside the driving ring 112, the driving ring 112 is disposed as an internal tooth; When the transmission mechanism 13 is disposed outside the drive ring 112, the drive ring 112 is disposed as an external tooth, which can be selected according to a specific situation.
