Description
Technical Field
[0001] The utility model relates to the technical field of food processing, in particular to a curved-edge rotary cutter group. Background Art
[0002] A rotary cutter group is a cutting tool that cuts in a rotating manner and is widely used in life, such as an electric mixer, a juicer, etc.
[0003] In order to avoid interference between the stirring blade and the container, a gap is left at the inner wall of the container and the stirring blade. The gap avoids interference between the blade and the inner wall of the container. At the same time, the existence of this gap also makes it difficult for the food ingredients near the inner wall of the container to be stirred and chopped. When the rotary cutter group stirs food ingredients in the container, due to the centrifugal force generated by the rotation of the stirring blade, the food ingredients will be thrown towards the inner wall of the container, resulting in the accumulation of food ingredients at the inner wall position of the container, affecting the stirring and chopping efficiency.
[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 shortcomings of the above-mentioned prior art, the purpose of the utility model is to provide a curved-edge rotary cutter group to make the stirred food ingredients more evenly distributed.
[0006] The technical solution of the utility model is as follows:
[0007] A curved-edge rotary cutter group includes: a rotating shaft; a first cutter group including a curved-edge cutter; wherein, the curved-edge cutter includes a first cutter body and a second cutter body; the first cutter body is connected to the rotating shaft, and the second cutter body is arranged at one end of the first cutter body far away from the rotating shaft; the included angle between the first cutter body and the second cutter body is: 90° to 175°; the cutting edge of the second cutter body faces the rotation direction of the second cutter body.
[0008] In a further technical solution, two second cutter bodies are arranged on one first cutter body, and the two second cutter bodies are symmetrically arranged with respect to the first cutter body to which they are connected.
[0009] In a further technical solution, a spline is arranged on the rotating shaft.
[0010] In a further technical solution, along the axis direction of the rotating shaft, two curved-edge cutters with different heights are arranged on the rotating shaft, and the second cutter bodies of the two curved-edge cutters are connected into a whole.
[0011] In a further technical solution, the first cutter group includes the curved-edge cutters arranged at intervals around the rotating shaft; the sizes of adjacent curved-edge cutters alternately change reciprocally.
[0012] A further technical solution is that a second knife group is further arranged on the rotating shaft, and the second knife group is composed of a curved-edge knife or blades.
[0013] A further technical solution is that the rotating shaft includes a shaft body and a shaft sleeve, the shaft sleeve is sleeved on the shaft body, and the first knife body is connected to the shaft sleeve.
[0014] A further technical solution is that at least two holding planes are arranged on the surface of the shaft sleeve, and edges are formed between adjacent holding planes.
[0015] A further technical solution is that the shaft body 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.
[0016] A further technical solution is that a transition surface is arranged between the first shaft section and the second shaft section.
[0017] The beneficial technical effects of the present utility model are as follows:
[0018] (1) In the curved-edge rotary knife group of the present utility model, the first knife group is composed of curved-edge knives. The curved-edge knife includes a first knife body and a second knife body that forms an angle with the first knife body. When the curved-edge rotary knife group rotates, the first knife body rotates to cut and stir the food ingredients, and the food ingredients will adhere to the first knife body. The inertia generated during the rotation of the first knife body causes the food ingredients to move along the first knife body, and the second knife body will limit the contacted food ingredients from being thrown to the side away from the rotating shaft. The food ingredients accumulate at the position on the first knife body close to the second knife body. When the accumulation reaches a certain degree, the food ingredients will fall into the position where the first knife body cuts the food ingredients, and the food ingredients will be cut and stirred again. At the same time, the second knife body can also scrape off some of the food ingredients on the inner wall of the container and cut and stir them through the first knife body, making the distribution of the food ingredients more uniform and improving the stirring effect.
[0019] (2) Further, a shaft sleeve is arranged on the shaft body, and the first knife group is arranged on the shaft sleeve. When replacing different shaft sleeves, the first knife group connected to the shaft sleeve is replaced at the same time. That is, by replacing the shaft sleeve, the first knife group on the rotating shaft can be quickly replaced to select the knife suitable for the current food ingredients.
[0020] (3) Further, the first knife group includes curved-edge knives arranged at intervals around the rotating shaft; the sizes of adjacent curved-edge knives change alternately. When the first knife group rotates, the second knife body restricts the movement of the food ingredients at positions at different distances from the shaft body respectively. In this way, the movement of the food ingredients is restricted at multiple levels, making the food ingredients more evenly distributed in the container. Description of the Drawings

[0029] Embodiment 1
[0030] Figure 1 Shows a three-dimensional structural schematic diagram of the curved-edge rotary cutter group in the first embodiment of the present utility model. Please refer to Figure 1, A curved blade rotary knife set, including a rotating shaft 1 and a first knife set 4. The first knife set 4 includes a curved blade knife 6. Among them, the curved blade knife 6 includes a first knife body 61 and a second knife body 62. The first knife body 61 is connected to the rotating shaft 1, and the second knife body 62 is provided at one end of the first knife body 61 away from the rotating shaft 1. The included angle between the first knife body 61 and the second knife body 62 is: 90° - 175°. When the angle between the first knife body 61 and the second knife body 62 < 90°, the included angle between the first knife body 61 and the second knife body 62 is too small, and it is easy to get food stuck in this angle, and it is not convenient to clean either.
[0031] Under the action of rotational inertia, the food attached to the first knife body 61 will move towards the included angle position between the first knife body 61 and the second knife body 62, and the second knife body 62 will block and restrict the food. If the angle between the first knife body 61 and the second knife body 62 is greater than 175°, then the area where the second knife body 62 restricts the movement of the food in the vertical direction is too small, and the restricting effect is small.
[0032] The cutting edge of the second knife body 62 faces the rotation direction of the second knife body 62, reducing the resistance when the second knife body 62 rotates, and also facilitating the cutting of food by the cutting edge of the second knife body 62.
[0033] When the curved blade rotary knife set rotates, the first knife body 61 rotates to cut and stir the food, and the food will adhere to the first knife body 61. The inertia generated by the rotation on the first knife body 61 causes the food to move along the first knife body 61, and the second knife body 62 will restrict the contacted food from being thrown to the side away from the rotating shaft 1. The food accumulates at the position on the first knife body 61 close to the second knife body 62. When it accumulates to a certain extent, the food will fall into the position where the first knife body 61 cuts the food, and the food is cut and stirred again. At the same time, the second knife body 62 can also scrape off some of the food on the inner wall of the container and cut and stir it through the first knife body 61, making the distribution of the food more uniform and improving the stirring effect.
[0034] The specific structure of the rotating shaft 1 is described as follows:
[0035] Please refer to Figure 1 , The rotating shaft 1 includes a shaft body 2 and a shaft sleeve 3. The shaft sleeve 3 is sleeved on the shaft body 2, and the first knife body 61 is connected to the shaft sleeve 3. When replacing different shaft sleeves 3, the first knife set 4 connected to the shaft sleeve 3 is also replaced. That is, by replacing the shaft sleeve 3, the first knife set 4 on the rotating shaft 1 can be quickly replaced to select the knife suitable for the current food. At least two holding planes 31 are provided on the surface of the shaft sleeve 3, and a corner is formed between adjacent holding planes 31. When the shaft sleeve 3 needs to be disassembled, hold the shaft sleeve 3 and apply force with the fingers contacting the holding planes 31. The holding planes 31 are planes, and a corner is formed between adjacent holding planes 31 to prevent the fingers from slipping.
[0036] Please refer to Figure 1, the shaft body 2 includes a first shaft section 21, a second shaft section 23, and a third shaft section 24. The diameter of the first shaft section 21 is smaller than that of the second shaft section 23, and the diameter of the second shaft section 23 is smaller than that of the third shaft section 24. A transition surface 22 is provided between the first shaft section 21 and the second shaft section 23, and the transition surface 22 smoothly connects the first shaft section 21 and the second shaft section 23. Since the diameter of the first shaft section 21 is smaller than that of the second shaft section 23, the two are connected by the transition surface 22. The small-diameter first shaft section 21 facilitates the installation of the shaft sleeve 3. When the shaft sleeve 3 moves from the first shaft section 21 to the second shaft section 23, the shaft sleeve 3 contacts the transition surface 22 and moves along the transition surface 22, facilitating the installation of the shaft sleeve 3 onto the shaft body 2. Since the diameter of the second shaft section 23 is smaller than that of the third shaft section 24, a step is formed between the second shaft section 23 and the third shaft section 24, and this step abuts against the shaft sleeve 3 to limit the installation height of the shaft sleeve 3. A spline 211 is provided on the rotating shaft 1, and the spline 211 is provided on the first shaft section 21. The curved-edge rotary cutter group is installed in the container, and the food ingredients are placed in the container. The driving device engages the spline 211 through a key coupling, and the driving device drives the curved-edge rotary cutter group to rotate in the container to cut the food ingredients.
[0037] Please refer to Figure 1 , a second cutter group 5 is further provided on the rotating shaft 1, and the second cutter group 5 is composed of a curved-edge cutter 6 or blades. The second cutter group 5 is directly connected to the rotating shaft 1, and the second cutter group 5 and the first cutter group 4 jointly rotate around the rotating shaft 1 to perform chopping and stirring, improving the chopping and stirring efficiency of the curved-edge rotary cutter group.
[0038] The specific working process of the present utility model is as follows:
[0039] The driving device engages the spline 211 through a key coupling to drive the shaft body 2 to rotate, driving the shaft sleeve 3, the first cutter group 4, and the second cutter group 5 to rotate synchronously to cut and stir the food ingredients in the container. The food ingredients tend to move to the side away from the rotating shaft 1 under the rotating action of the curved-edge rotary cutter group. During this process, the second cutter body 62 at an angle with the first cutter body 61 hinders the movement of the food ingredients, making the food ingredients more evenly distributed in the container and preventing the food ingredients from accumulating on the inner wall of the container.
[0040] Embodiment 2
[0041] Figure 2 Shows a three-dimensional structural schematic diagram of the curved-edge cutter of the curved-edge rotary cutter group in Embodiment 2 of the present utility model. Please refer to Figure 2, based on Embodiment 1, Embodiment 2 discloses a curved-edge knife 6. Two second knife bodies 62 are arranged on the first knife body 61 of the curved-edge knife 6, and the two second knife bodies 62 are symmetrically arranged with respect to the first knife body 61 to which they are connected. Preferably, at this time, the included angle between the first knife body 61 and the second knife body 62 is 90°, to avoid forming an acute angle between the first knife body 61 and the second knife body 62, as an acute angle is likely to get stuck with food ingredients and is not convenient for cleaning either. The two second knife bodies 62 increase the area where the second knife body 62 blocks the movement of materials. They can simultaneously hinder the materials above and below the first knife body 61, making the distribution of the materials more uniform and improving the stirring effect.
[0042] Embodiment 3
[0043] Figure 3 Fig. shows a partial structural schematic diagram of the curved-edge rotary knife group in Embodiment 3 of the present utility model. Please refer to Figure 3 , based on Embodiment 1, Embodiment 3 discloses a pair of cooperating curved-edge knives 6. Along the axial direction of the rotating shaft 1, two curved-edge knives 6 with different heights are arranged on the rotating shaft 1, and the second knife bodies 62 of the two curved-edge knives 6 are connected into a whole. At this time, the included angle between the second knife body 62 and the first knife body 61 is 90°. With such a setting, both the upper and lower ends of the second knife body 62 are connected to the first knife body 61, and the first knife body 61 fixes the two ends of the second knife body 62, strengthening the stability of the second knife body 62. At the same time, the length of the second knife body 62 in the up and down direction is relatively long, and the second knife body 62 can scrape off more food ingredients from the inner wall of the container.
[0044] Embodiment 4
[0045] Figure 4 Fig. shows a top view structural schematic diagram of the shaft sleeve of the curved-edge rotary knife group and the first knife group in Embodiment 4 of the present utility model. Please refer to Figure 4 , based on Embodiment 1, Embodiment 4 discloses a first knife group 4. The first knife group 4 includes curved-edge knives 6 arranged at intervals around the rotating shaft 1; the sizes of adjacent curved-edge knives 6 alternately change reciprocally.
[0046] In this embodiment, the number of curved-edge knives 6 is 4 groups, including two groups of curved-edge knives 6 with larger sizes and two groups of curved-edge knives 6 with smaller sizes. The two groups of curved-edge knives 6 with larger sizes and the two groups of curved-edge knives 6 with smaller sizes are alternately arranged reciprocally. With such a setting, the distances between the second knife bodies 62 on different curved-edge knives 6 and the shaft body 2 are also different. When the curved-edge rotary knife group rotates, the second knife bodies 62 limit the movement of the food ingredients at positions with different distances from the shaft body 2 respectively. Restricting the movement of the food ingredients in such a multi-level manner makes the food ingredients more evenly distributed in the container.
[0047] It can be seen that when the above-mentioned curved-edge rotary knife group rotates, the second knife body 62 of the curved-edge knife 6 with a smaller size is far from the inner wall of the container. The second knife body 62 of the curved-edge knife 6 with a smaller size will limit the accumulation of food materials on the inner wall of the container, making the distribution of food materials in the container more uniform and improving the stirring effect.
[0048] 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.
[0049] The above embodiments only express several implementation manners of the present invention, and the description is relatively specific and detailed. However, it should not be understood as a limitation to 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 invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
