Description

Technical Field

[0001] The utility model relates to the technical field of mixing cutters, in particular to a mixer cutter. Background Art

[0002] With the development of technology, the functions of blenders have become increasingly diverse. In addition to blending food, there is also a demand for blending ice. Currently, most blender blades on the market use a parallel blending method, that is, the blades are arranged in parallel on the rotating shaft and cut the ice by rotation. Although this can crush ice to a certain extent, the gaps between the blades are often large due to the parallel arrangement of the blades, and a tight shear force cannot be formed. As a result, the ice is easily pushed out of the blending area during the blending process, or some ice is over-cut while others remain in larger blocks, making it impossible to effectively cut the ice, thereby reducing the uniformity and efficiency of ice crushing. Therefore, it is necessary to improve the existing technology to solve the above problems. Utility Model Content

[0027] The present invention will be described in detail below with reference to specific embodiments.

[0028] In the present utility model, unless otherwise expressly provided and limited, when terms such as "set on", "connected", and "connected" appear, these terms should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or integrally connected; they can be directly connected or connected through one or more intermediate media. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances. The directional words that appear in the present utility model are for the purpose of better explaining the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of the present utility model changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.

[0029] The utility model provides a blender cutter, such as Figures 1 to 8 As shown, it includes a cutter shaft assembly 1 and a blade assembly 2, the blade assembly 2 includes an upper blade 21, a middle blade 22 and a lower blade 23, and the upper blade 21, the middle blade 22 and the lower blade 23 are sequentially mounted on the cutter shaft assembly 1 from top to bottom; in the vertical projection direction, the middle blade 22 is arranged at 90 degrees to the upper blade 21 and the lower blade 23;

[0030] The upper blade 21 includes an upper flat portion 211 and two upper inclined portions 212 extending upwardly obliquely from both sides of the upper flat portion 211, and the upper inclined portion 212 is triangular; the middle blade 22 includes a middle flat portion 221, two first-level middle inclined portions 222 extending upwardly obliquely from both sides of the middle flat portion 221, and two second-level middle inclined portions 223 extending upwardly obliquely from the two first-level middle inclined portions 222, the first-level middle inclined portion 222 is trapezoidal, and the second-level middle inclined portion 223 is triangular; the lower blade 23 includes a lower flat portion 231 and two lower inclined portions 232 extending downwardly obliquely from both sides of the lower flat portion 231, and the lower inclined portion 232 is triangular; The upper inclined portion 212 of the blade 21 is provided with a flat-edge blade head 213. The design of the flat-edge blade head 213 enables the upper blade 21 to smoothly cut into the ice cubes and play a role in preliminary mixing and dispersion during the stirring process; the secondary middle inclined portion 223 of the middle blade 22 is provided with a toothed blade head 224. The design of the toothed blade head 224 enables the middle blade 22 to have stronger cutting and crushing capabilities, and can effectively cut larger ice cubes; the lower inclined portion 232 of the lower blade 23 is provided with a beveled blade head 233. The design of the beveled blade head 233 helps to form a vortex effect, accelerate the flow and mixing of ice cubes and can effectively cut smaller ice cubes.

[0031] Based on the above structural setting, when working, the upper blade 21 plays a role of rapid stirring, while the middle blade 22 can cut larger ice cubes from above, forming a cutting force from top to bottom, and the lower blade 23 cuts smaller ice cubes from below, forming a cutting force from bottom to top, which complements the upper blade 21 and the middle blade 22 to jointly improve the ice crushing efficiency, while avoiding the situation where the ice cubes are locally too large or too small, and improving the uniformity of ice crushing.

[0032] In this embodiment, in the vertical projection direction, the length of the upper blade 21 is L1, the length of the middle blade 22 is L2, and the length of the lower blade 23 is L3, where L1 < L2 < L3. This configuration of blades of varying lengths and types allows the blender to more efficiently blend and crush ice, improving production efficiency.

[0033] In this embodiment, an angle ∠1 is formed between the upper inclined portion 212 and the upper flat portion 211 , and the range of ∠1 is 60°≤∠1≤65°. More preferably, ∠1 is 63°.

[0036] By configuring the blades with different inclination angles as mentioned above, the crushing area in the axial direction can be increased and the effective cutting space can be increased. If the inclination angle is too small, the increased crushing area will be small. If the inclination angle is too large, cavities will easily be formed, affecting the crushing effect and efficiency.

[0037] In this embodiment, the length L11 of the upper inclined portion 212 is 19-23 mm, more preferably, L11 is 21 mm; the length L21 of the first-stage middle inclined portion 222 is 8-12 mm, more preferably, L21 is 10 mm; the length L22 of the second-stage middle inclined portion 223 is 21-25 mm, more preferably, L22 is 23 mm; the length L31 of the lower inclined portion 232 is 18-22 mm, more preferably, L31 is 20 mm. Different inclined extension lengths can be used to adapt to the flow characteristics of different materials, thereby achieving more efficient stirring and improving the mixing speed and uniformity between materials.

[0038] In this embodiment, the thickness of the upper blade 21, the middle blade 22 and the lower blade 23 are all 1.2 mm.

[0039] The thickness of each blade is the best choice after taking into account both production cost and use effect.

[0040] In this embodiment, the knife shaft assembly 1 includes a limit screw 11 and a rotating shaft 12; the upper blade 21, the middle blade 22 and the lower blade 23 are all provided with mounting holes 24, and the two ends of the rotating shaft 12 are respectively provided with a first mounting portion 121 and a second mounting portion 122, and the limit screw 11 is provided with a limit portion 111 and a locking portion 112. The locking portion 112 of the limit screw 11 passes through the mounting holes 24 of the upper blade 21, the middle blade 22 and the lower blade 23 in turn and is locked in the first mounting portion 121, and the limit portion 111 presses against the upper blade 21.

[0041] In this embodiment, the blender cutter further comprises a cutter holder 3, and the second mounting portion 122 is mounted on the cutter holder 3. Through the above structural design, a tight connection between each blade and the cutter holder can be achieved, thereby improving the operational stability of the cutter.

[0042] In summary, this type of blender blade can solve the problem in the prior art that most blender blades adopt a parallel mixing method, which reduces the uniformity and efficiency of ice crushing.

[0043] In the absence of conflict, the above embodiments and features therein may be combined with each other.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model.
