Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a grinding cutter head and a grinding machine thereof. Background Art

[0002] The existing household grinder mainly installs a set of crushing blades in the cavity of the grinder, controls the crushing blades to rotate at high speed, thereby impacting and cutting the food, and finally achieving the crushing effect.

[0003] The crushing blade heads used in existing household grinders are mostly of a "I"-shaped structure with two blade wings. For example, CN213721573U discloses a blade assembly structure and a household appliance, whose blades are double-winged "I"-shaped. This type of blade head must rely on the up and down movement of the blade shaft when crushing, otherwise the contact volume space between it and the food is small, making it difficult to achieve a good crushing effect.

[0004] At present, some grinding machines on the market have four-wing or multi-wing blade heads that are obtained by stacking and fixing multiple layers of "I"-shaped structures. This blade head structure helps to increase the contact space with the food to a certain extent, but the structure is relatively complicated, and installation and disassembly are not convenient enough. Utility Model Content

[0005] The utility model aims to provide a grinding blade head and a grinding machine thereof, so as to solve the technical problems in the prior art that the grinding blade head of the grinding machine has a small contact space with food materials and is inconvenient to install.

[0006] The technical solution of the utility model is as follows:

[0007] A grinding cutter head comprises a cutter body, an axial hole provided in the middle of the cutter body for installing a cutter shaft, and a plurality of blade wing groups provided at the periphery of the cutter body and integrally formed with the cutter body; the blade wing group comprises a first blade wing, a second blade wing and a third blade wing; the first blade wing comprises an extension portion extending outward from the cutter body and a bending portion bending upward from the extension portion; the second blade wing is cut into a wing shape on the cutter body and bent upward, and a flow hole is formed at the cutting position; the third blade wing is spaced apart from the first blade wing and bent downward from the periphery of the cutter body.

[0008] The following are further defined technical solutions, but are not intended to be limitations of the aforementioned technical solutions.

[0009] The extension portion of the first blade wing is at the same level as the blade body, and the angle between the bent portion and the extension portion is 140-160°, preferably 150°; the angle between the second blade wing and the blade body is 130-150°, preferably 135°; the angle between the third blade wing and the blade body is 150-170°, preferably 160°.

[0010] The end of the bent portion of the first blade wing is rounded; the ends of the second blade wing and the third blade wing are arc-shaped.

[0011] One side of the first blade is provided with a plurality of saw teeth.

[0012] The fold between the first blade wing bending portion and the extension portion, the fold between the second blade wing and the blade body, and the fold between the third blade wing and the blade body are all rounded transitions.

[0013] The ends of the saw teeth are rounded, and the saw teeth are transitioned with rounded corners.

[0014] The number of blade wing groups is 3-5.

[0015] The utility model also claims to protect a grinding machine, in which the grinding cavity is fixed with the grinding cutter head via a cutter shaft.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0017] (1) The grinding blade head of the utility model has a horizontal spatial position difference formed by the second blade wing, the third blade wing, the first blade wing extension, and the first blade wing bending portion from the axial hole to the outside, and a longitudinal spatial position difference formed by the third blade wing, the first blade wing extension, the first blade wing bending portion, and the second blade from the axial direction to the top, so that the spatial volume that the grinding blade head can contact with the food is significantly increased, which helps to improve the crushing effect and efficiency.

[0018] (2) The utility model not only achieves the best crushing effect, but also helps to avoid the blade from breaking when the cutter head rotates at high speed, thereby improving durability, through the three sets of blade specific bending angles, crease radius transitions, and sawtooth radius transitions.

[0019] (3) The utility model sets the end of the bending portion of the first blade to be rounded, and sets the ends of the second blade and the third blade to be arc-shaped, which can avoid working wear and further improve durability.

[0020] (4) When the grinding blade head of the utility model is in operation, the bending portion of the first blade wing can gather the crushed food materials in the middle of the blade body, and the second blade wing on the blade body crushes the food materials again. The crushed food materials will not be retained on the blade body due to the rotating flow, but will flow downward along the flow holes opened on the blade body, and can be crushed again by the third blade wing, thereby further improving the crushing effect.
