[0036] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0037] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, inside, outside, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0038] In the description of the present invention, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0039] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0040] The tool assembly of an existing pelletizer usually drives the blade to rotate to complete the pelletizing of food. The blades are usually arranged in multiple directions along the circumference, and a discharge port is opened at the blades. In this solution, two adjacent blades are located one in front of the other, blocking each other and unable to cut the food at the same time, resulting in low utilization of the tool assembly. Even if multiple blades are provided, the blades rotate one circle, and the food falling at the radial intervals of the blades cannot be cut. The blades need to cut multiple times to cut the food into pellets, and the pelletizing efficiency is also low.

[0041] Reference Figure 1 As shown, the tool assembly 1 of an embodiment of the present invention includes a rotating shaft 100, a first blade 200, a first turntable 300 and a second blade 400. The first blade 200, the second blade 400 and the first turntable 300 are arranged at intervals along the axial direction of the rotating shaft 100. The first blade 200 cuts the food into blocks, and the second blade 400 cuts the block-shaped food into granules. No manual labor is required, which facilitates daily cooking.

[0042] Specifically, refer to Figure 1As shown, the first blade 200 is arranged horizontally and is fixedly connected to the rotating shaft 100. Since the first blade 200 is arranged horizontally, the first blade 200 can cut the food into blocks horizontally. The first turntable 300 is arranged below the first blade 200 and is sleeved on the rotating shaft 100, so that the rotating shaft 100 can drive the first turntable 300 to rotate. The surface of a part of the first turntable 300 is axially upwardly protruded to form a boss 310. The side wall of the boss 310 is provided with an opening 311, and the opening 311 extends along the radial direction of the first turntable 300, so that the opening 311 rotates around the rotating shaft 100 once and sweeps the ground. The trajectory can cover all ingredients. The second blade 400 is arranged on the top of the boss 310. The second blade 400 is fixedly connected to the boss 310, so that the first turntable 300 can drive the second blade 400 to rotate. A plurality of extensions 410 are arranged at intervals at the edge of the second blade 400. The plurality of extensions 410 are arranged along the length direction of the second blade 400. The plurality of extensions 410 are covered in the opening 311. The extensions 410 are roughly strip-shaped. The extensions 410 are bent into the opening 311. A single extension 410 is specifically L-shaped, and the plurality of extensions 410 are overall rake-like structures.

[0043] It should be noted that there are two situations in which the opening 311 extends radially along the first turntable 300: one is that it extends completely and strictly along the radial direction of the first turntable 300, extending straight along the radius of the first turntable 300, and forming a straight line; the other is that it extends incompletely along the radial direction of the first turntable 300, and can deviate from the radial direction of the first turntable 300, forming an arc-shaped line. This is sufficient to achieve the effect that the opening 311 can cover all food materials in the trajectory it sweeps around the rotating shaft 100, and is not limited here. Since the opening 311 can cover all food materials, the multiple extensions 410 can cut all food materials, which can improve the cutting efficiency of the tool assembly 1. Since the extensions 410 are arranged in a continuous and spaced manner, the rotating shaft 100 can rotate once to drive multiple extensions 410 to cut food materials simultaneously, thereby improving utilization. Moreover, since the multiple extensions 410 are adjacent to each other, two adjacent extensions 410 will not interfere with each other, further improving the utilization rate of the second blade 400.

[0044] It should be noted that the terms “left and right” refer to the width direction of the extension portion 410 , which is the same as the length direction of the second blade 400 .

[0045] Reference Figure 1As shown, it can be understood that a first discharge port 411 is defined between two adjacent extension portions 410. Only when the shape and size of the food is smaller than the first discharge port 411 can it leave the first discharge port 411, which can ensure that all the cut food is cut into granules, avoiding uneven cutting of food, and further enhancing the granulation effect. A sharp end 412 is provided at one end of the extension portion 410 along the width direction. When the rotating shaft 100 drives the second blade 400 to rotate, the food is cut into granules through the sharp end 412. It can be understood that the extension portion 410 can also be provided with a sharp end 412 at both ends along the width direction. When the extension portion 410 is provided with a sharp end 412 only at one end along the width direction, the granulation effect is better and cost can be saved.

[0046] Reference Figure 2 and Figure 4 As shown, it can be understood that the opening 311 is arc-shaped, so that the extension portion 410 of the second blade 400 is also arranged along the arc. More extension portions 410 can be provided to improve the pelletizing efficiency and make the pelletizing more uniform.

[0047] It can also be understood that the above-mentioned extension portion 410 can also be arranged along a spiral line. Since the length of the spiral line is longer, the second blade 400 can also be set longer, so that more extension portions 410 can be set to cut more food, further improving the dicing efficiency, and when the food is located at the edge of the first turntable 300, since the extension portion 410 is arranged along the spiral line, the space here becomes smaller and smaller, and the food is squeezed, making it easier for the extension portion 410 to cut the food. It should be noted that when the extension portion 410 is arranged along the spiral line, the opening 311 also extends along the spiral line accordingly, so that the extension portion 410 can bend into the opening 311 and cover the opening 311.

[0048] Reference Figure 1 As shown, it should be noted that the first blade 200 is fixedly connected to the rotating shaft 100 through a mounting piece. The first blade 200 and the mounting piece are an integral piece or a detachable piece. A spline hole is provided in the middle of the mounting piece. Correspondingly, a spline that matches the spline hole is provided on the rotating shaft 100. The transmission is achieved through the spline and the spline hole, so that the force on the rotating shaft 100 is more balanced, and the first blade 200 can be easily disassembled for easy replacement.

[0049] Reference Figure 1 and Figure 4As shown, it should be noted that the second blade 400 is connected to the boss 310 by screws, and the second blade 400 can be removed from the boss 310. When the second blade 400 is worn, it can be easily replaced. Of course, the second blade 400 and the boss 310 can also use other forms of detachable connection, such as a snap connection, and a snap connection portion is set at the corresponding position of the second blade 400 and the boss 310 to achieve a snap connection, or a slot and a snap connection portion can also be set to achieve a snap connection, which is not limited here.

[0050] Reference Figure 1 and Figure 2 As shown, it should be noted that the number of extension parts 410 can be set according to the actual size of the first turntable 300. In this embodiment, the number of extension parts 410 is 7, which has a better effect and can fully utilize space and save costs.

[0051] It is understandable that those skilled in the art can set the spacing distances between the multiple extensions 410 accordingly according to the actual usage scenario. For example, when designed specifically for a specific food, the spacing distances between the extensions 410 can be set accordingly according to the optimal size of the food, so that the first discharge port 411 defined between the extensions 410 matches the optimal size, thereby achieving the effect of controlling the pelletizing effect.

[0052] Reference Figure 2 and Figure 3 As shown, the extension portion 410 is arranged along an arc line, and the extension portion 410 is inclined in a direction away from the rotating shaft 100 and forms an inclination angle θ, so that when the sharp end 412 of the extension portion 410 cuts the food, the sharp end 412 coincides or roughly coincides with the normal of the surface of the cutting point of the food, the cutting force of the sharp end 412 is more concentrated, the sharp end 412 can cut the food more smoothly, the dicing effect is better, the stress on the sharp end 412 can be reduced, and the driving force for driving the rotating shaft 100 to rotate can be saved. At the same time, the durability of the second blade 400 can be increased. It can be understood that when the inclination angle θ is 55 degrees to 70 degrees, the above-mentioned effect is better achieved.

[0053] Reference Figure 4 As shown, it can be understood that for the extension portion 410 of the second blade 400 mentioned above, the first discharge port 411 defined between adjacent extension portions 410 rotates around the rotating shaft 100 and the trajectory swept by is a circular ring, and multiple extension portions 410 are arranged at intervals so that the area S of each circular ring is equal. At this time, since the area S of each circular ring is equal and the inner diameter of each circular ring is equal, the size of each first discharge port 411 is the same. When the sharp end 412 of the extension portion 410 cuts food, each piece of food cut out can be made uniform in size and beautiful in shape, further improving the pelletizing effect.

[0054] Reference Figure 1 and Figure 4 As shown, it can be understood that for the above-mentioned tool assembly 1, the tool assembly 1 includes two second blades 400, and the two second blades 400 are arranged relative to each other, which can save costs while maximizing the pelletizing efficiency. The first discharge port 411 is facing the rotation direction of the rotating shaft 100 to ensure that the food can be cut. Overall, the two second blades 400 are staggered with respect to each other in a straight line of diameter relative to the first turntable 300.

[0055] It should be noted that the second blade 400 can also be set to single or multiple. For example, based on the arrangement of the two second blades 400 mentioned above, any one of the second blades 400 can be deleted, or an additional second blade 400 can be added based on the arrangement of the two blades mentioned above, as long as the effect of facilitating cutting is achieved. This is not limited here.

[0056] Reference Figure 1 As shown, the first blade 200 is in an arc shape, and the width of the first blade 200 gradually decreases in the direction away from the rotating shaft 100. It can be understood that when the first blade 200 is in a crescent shape, the effect is better.

[0057] Reference Figure 1 As shown, the tool assembly 1 includes two first blades 200 , which are arranged opposite to each other, thereby saving costs while maximizing the cutting efficiency.

[0058] It should be noted that the first blade 200 can also be set to single or multiple. For example, based on the arrangement of the two first blades 200 mentioned above, any one of the first blades 200 can be deleted, or an additional first blade 200 can be added based on the arrangement of the two blades mentioned above, as long as the effect of facilitating cutting is achieved. This is not limited here.

[0059] Reference Figure 3 As shown, it can be understood that for the above-mentioned second blade 400, the second blade 400 is provided with a bending section 413, and the bending section 413 can cause the sharp end 412 to deviate outward. When the sharp end 412 rotates around the rotating shaft 100, the sharp end 412 can easily cut the food and reduce stress concentration.

[0060] Reference Figure 5 and Figure 6As shown, the pelletizer 2 of the embodiment of the present invention includes the tool assembly 1, a driving device, a sealing cylinder 600 and a receiving cylinder 700 of the above embodiment. The driving device can drive the tool assembly 1 to rotate. The driving device can be set as a motor. The tool assembly 1 is installed in the sealing cylinder 600. The rotating shaft 100 of the tool assembly 1 is connected to the output shaft of the driving device. The top of the sealing cylinder 600 is provided with a feed port 610, and the side wall of the sealing cylinder 600 is provided with a second discharge port 620. The tool assembly 1 also includes a second turntable 500 and a blade 510. The second turntable 500 is sleeved on the rotating shaft 100, so that the rotating shaft 100 can drive the second turntable 500 to rotate. The blade 510 is provided on the second turntable 500. The blade 510 is vertically arranged and can The food is transferred into the second discharge port 620. When in use, the food is placed into the feed port 610, the driving device is started, and the driving device drives the rotating shaft 100 to rotate. The first blade 200 cuts the food into blocks. Under the action of gravity, the food falls on the first turntable 300. Squeezed by the side wall of the sealing cylinder 600, the block-shaped food is cut by the second blade 400 to form smaller particles. Since the extension part 410 of the second blade 400 can cut the food at the same time, and the extension parts 410 are adjacent to each other on the left and right, mutual obstruction can be avoided, thereby improving the particle cutting efficiency. The granular food falls into the second turntable 500 through the first discharge port 411, is transferred out of the second discharge port 620 by the blade 510, and falls into the receiving cylinder 700 to complete the collection. The whole process is completed automatically without the need for manual labor.

[0061] It can be understood that the tool assembly 1 of the above embodiment is not limited to use in a pelletizer 2, but can also be used in kitchen appliances such as a food processor and a blender. Any changes in the use of the tool assembly 1 by technicians familiar with the field without violating the principles of this application are included in the protection scope of the present invention.

[0062] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
