Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of food processing, in particular to a waveform rotary cutter group. Background Art
[0002] A rotary cutter group is a cutting tool that cuts food ingredients in a rotating manner and is widely used in daily life, such as electric blenders, juicers, etc.
[0003] The blades on the rotary cutter group rotate around the rotating shaft in the container for chopping and stirring. When the blades rotate, the effective working area in the height direction is small. The food ingredients above and below the blades are not easily chopped and stirred by the blades. Moreover, the surface of the blade is flat, and the centrifugal force generated when the blade rotates will throw the food ingredients onto the inner surface of the container. There is a gap between the end of the blade and the container, and the food ingredients here are even less likely to be chopped and stirred, affecting the efficiency of stirring and chopping.
[0004] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Utility Model
[0005] Aiming at the above-mentioned disadvantages of the prior art, the purpose of the utility model is to provide a waveform rotary cutter group to improve the efficiency of chopping, stirring and cutting.
[0006] The technical solution of the utility model is as follows:
[0007] A waveform rotary cutter group includes: a rotating shaft; a shaft sleeve sleeved on the rotating shaft; a first cutter group connected to the shaft sleeve, including: a waveform cutter, along the axial direction of the rotating shaft, the cutter surface of the waveform cutter is undulating in a wave shape; wherein, the waveform cutter includes at least one wave crest and at least one wave trough, and the wave crest and the wave trough are arranged alternately.
[0008] In a further technical solution, towards the direction away from the rotating shaft, the undulation of the waveform cutter gradually decreases.
[0009] In a further technical solution, the height of the wave crest and the wave trough ≥ 1 mm; along the length direction of the waveform cutter, the distance between adjacent wave crest and wave trough ≥ 3 mm.
[0010] In a further technical solution, the waveform cutter includes at least three blades; along the axial direction of the rotating shaft, the blades of the same waveform cutter are superposed on each other.
[0011] In a further technical solution, a hollowed-out part is arranged on the waveform cutter.
[0012] In a further technical solution, a second cutter group is arranged on the rotating shaft.
[0013] A further technical solution is that the rotating shaft includes a first shaft section, a second shaft section, and a third shaft section. The diameter of the first shaft section is smaller than that of the second shaft section, and the diameter of the second shaft section is smaller than that of the third shaft section.
[0014] A further technical solution is that a transition surface is provided between the first shaft section and the second shaft section.
[0015] A further technical solution is that at least two holding planes are provided on the outer side of the shaft sleeve, and edges are formed between adjacent holding planes.
[0016] A further technical solution is that a spline is provided at one end of the rotating shaft.
[0017] The beneficial technical effects of the present utility model are as follows:
[0018] (1) In the waveform rotary knife group of the present utility model, the first knife group is composed of waveform knives. The knife surface of the waveform knife is undulating in a wave shape, forming wave crests and wave troughs alternately. The undulating knife surface of the waveform knife enhances the effective working area of the waveform knife in the vertical direction. Moreover, the undulating knife surface of the waveform knife restricts the movement of the cut food ingredients away from the rotating shaft direction, keeping more food ingredients within the working area of the waveform knife, thus improving the shredding efficiency. At the same time, due to the undulation of the knife surface, the waveform knife can contact food ingredients at different heights, which also improves the stirring effect of the waveform knife.
[0019] (2) Further, along the direction away from the rotating shaft, the undulation of the waveform knife gradually decreases. So that the undulation of the waveform knife near the rotating shaft side is more intense. Because the translational speed of the waveform knife near the rotating shaft side is lower, the stirring effect on the food ingredients is poorer. Expanding the undulation degree of the knife surface near the rotating shaft side can effectively improve the stirring effect.
[0020] (3) Further, a second knife group is provided on the rotating shaft. The second knife group and the first knife group rotate around the rotating shaft together to perform shredding and stirring, improving the shredding and stirring efficiency of the waveform rotary knife group.

[0030] Embodiment 1
[0031] Figure 1 The three-dimensional structural schematic diagram of the waveform rotary knife group in the first embodiment of the present utility model is shown. Figure 2 The vertical sectional structural schematic diagram of the waveform knife of the waveform rotary knife group in the first embodiment of the present utility model is shown. Please refer to Figure 1 and Figure 2, A waveform rotary cutter group, comprising a rotating shaft 1, a shaft sleeve 2 and a first cutter group 3. The shaft sleeve 2 is sleeved on the rotating shaft 1, and the first cutter group 3 is connected to the shaft sleeve 2. The first cutter group 3 includes a waveform cutter 5. Along the axial direction of the rotating shaft 1, the cutter surface of the waveform cutter 5 is undulating like a wave. Among them, the waveform cutter 5 includes at least one wave crest 51 and at least one wave trough 52, and the wave crest 51 and the wave trough 52 are arranged alternately. The undulating cutter surface of the waveform cutter 5 enhances the effective working area of the waveform cutter 5 in the vertical direction. And the undulating cutter surface of the waveform cutter 5 contacts the food to be cut, restricting the food to be cut from moving away from the rotating shaft 1, allowing more food to stay within the working area of the waveform cutter 5 and improving the chopping efficiency. At the same time, due to the undulation of the cutter surface, the waveform cutter 5 can contact foods at different heights, which also improves the stirring effect of the waveform cutter 5.
[0032] Among them, the height of the wave crest 51 and the wave trough 52 ≥ 1 mm. This restricts the minimum undulation degree of the cutter surface to ensure the effective working area of the waveform cutter 5 in the height direction. At the same time, when the cutter group rotates, under the action of centrifugal force, the food attached to the surface of the waveform cutter 5 has a tendency to move towards and accumulate on the inner surface of the container. At this time, the undulating cutter surface of the waveform cutter 5 can restrict the movement of the food attached to the cutter surface, avoid food accumulation, and make the food more evenly distributed in the container. In addition, along the length direction of the waveform cutter 5, the distance between adjacent wave crests 51 and wave troughs 52 ≥ 3 mm. This avoids the distance between the wave crest 51 and the wave trough 52 being too small, so that food particles cannot attach to the wave crest 51 and the wave trough 52 and be restricted from moving by the cutter surface.
[0033] The specific structures of the rotating shaft 1 and the shaft sleeve 2 are described as follows:
[0034] Please refer to Figure 1 , A second cutter group 4 is provided on the rotating shaft 1. The second cutter group 4 can be an ordinary cutter or the waveform cutter 5 in this application. The second cutter group 4 and the first cutter group 3 rotate around the rotating shaft 1 together for chopping and stirring, improving the chopping and stirring efficiency of the waveform rotary cutter group.
[0035] Please refer to Figure 1, the rotating shaft 1 includes a first shaft section 11, a second shaft section 13, and a third shaft section 14. The diameter of the first shaft section 11 is smaller than that of the second shaft section 13, and the diameter of the second shaft section 13 is smaller than that of the third shaft section 14. The bushing 2 is sleeved on the second shaft section 13. Since the diameter of the first shaft section 11 is smaller than that of the second shaft section 13, the bushing 2 can be conveniently installed on the second shaft section 13. Since the diameter of the second shaft section 13 is smaller than that of the third shaft section 14, a step is formed between the second shaft section 13 and the third shaft section 14, and this step abuts against the bushing 2 to limit the installation height of the bushing 2. A transition surface 12 is provided between the first shaft section 11 and the second shaft section 13, and the transition surface 12 smoothly connects the first shaft section 11 and the second shaft section 13. When the bushing 2 moves from the first shaft section 11 to the second shaft section 13, the bushing 2 contacts the transition surface 12 and moves along the transition surface 12, facilitating the installation of the bushing 2 onto the rotating shaft 1. A spline 111 is provided at one end of the rotating shaft 1, and the spline 111 is provided on the first shaft section 11. The waveform rotary cutter group is installed in the container, and the food ingredients are placed in the container. The driving device meshes with the spline 111 through a spline coupling, and the driving device drives the waveform rotary cutter group to rotate in the container to cut the food ingredients.
[0036] Please refer to Figure 1 , at least two holding planes 21 are provided on the outer side of the bushing 2, and an edge is formed between adjacent holding planes 21. Through the holding planes 21, the bushing 2 can be conveniently held. The bushing 2 and the rotating shaft 1 can be connected by threads.
[0037] The specific working process of the present utility model is as follows:
[0038] The rotating shaft 1 rotates, driving the bushing 2, the first cutter group 3, and the second cutter group 4 to rotate synchronously. During the rotation of the waveform cutter 5, the undulating cutting surface of the waveform cutter 5 covers a larger space in the up and down directions to chop more food ingredients. Additionally, affected by the centrifugal force, the food ingredients will move to the side away from the rotating shaft 1. At this time, the undulating cutting surface of the waveform cutter 5 restricts the movement of the food ingredients, and the food ingredients stay more within the coverage range of the waveform cutter 5.
[0039] Embodiment Two
[0040] Figure 3 Shows a schematic vertical cross-sectional structure diagram of the waveform cutter of the waveform rotary cutter group in Embodiment Two of the present utility model. Please refer to Figure 3 , based on Embodiment One, Embodiment Two discloses a waveform cutter 5. Along the direction away from the rotating shaft 1, the undulation of the waveform cutter 5 gradually decreases. This makes the undulation of the waveform cutter 5 closer to the rotating shaft 1 more intense. Because the translational speed of the waveform cutter 5 closer to the rotating shaft 1 is lower, the stirring effect on the food ingredients is poorer. Expanding the undulation degree of the cutting surface closer to the rotating shaft 1 can effectively improve the stirring effect.
[0041] Embodiment Three
[0042] Figure 4 FIG. 2 shows a schematic structural view of the blade of the corrugated knife of the corrugated rotary knife set in the third embodiment of the present utility model. Figure 5 FIG. 3 shows a three-dimensional structural view of the corrugated knife of the corrugated rotary knife set in the third embodiment of the present utility model. Please refer to Figure 4 and Figure 5 , based on the first and second embodiments, the third embodiment discloses a corrugated knife 5, on which a hollowed-out portion 53 is provided. The hollowed-out portion 53 reduces the weight of the blade 54 and the load of the driving device. At the same time, when the corrugated knife 5 rotates, the food ingredients can pass through the blade 54 from the hollowed-out portion 53, disturbing the moving path of the food ingredients and improving the stirring effect.
[0043] Please refer to Figure 5 , the corrugated knife 5 includes at least three blades 54. Along the axial direction of the rotating shaft 1, the blades 54 of the same corrugated knife 5 are superposed on each other, and a gap is left between adjacent blades 54. The corrugated knife 5 having multiple blades 54 makes the vertically covered area of the corrugated knife 5 larger. And when the food ingredients impact one blade 54, they often contact another adjacent blade 54 at the same time, so that the food ingredients can be cut by the blade 54 and the adjacent blade 54 at the same time. That is, for each rotation of the corrugated knife 5 around the rotating shaft 1, the food ingredients can be cut more times, improving the cutting efficiency of the food ingredients. At the same time, the increase in the number of blades 54 can also better stir the food ingredients.
[0044] It can be seen that the corrugated knife 5 in the above-mentioned corrugated rotary knife set, its undulating knife surface enhances the effective working area of the corrugated knife 5 in the vertical direction. And the undulating knife surface of the corrugated knife 5 restricts the food ingredients to be cut from moving away from the rotating shaft 1, allowing more food ingredients to stay within the working area of the corrugated knife 5 and improving the shredding efficiency. At the same time, the undulation of the knife surface will also improve the stirring effect of the corrugated knife 5.
[0045] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
[0046] The above embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
