Description

Technical Field

[0001] This utility model relates to a food processing knife, and more specifically, to a grater barrel and a grater with the grater barrel. Background Technology

[0002] In food preparation and cooking, seasoning ingredients such as minced ginger and minced garlic are indispensable. However, it is not easy to process ginger and garlic into a fine paste. Ordinary knife cutting often results in insufficient fineness and poor seasoning effect. On the other hand, it is time-consuming and laborious to cut them into small pieces, which is always a headache.

[0003] Currently, manual graters exist in existing technology. These typically consist of a stainless steel plate with several grating holes. Users slide ginger and garlic back and forth across these holes to grate them into a paste. While simple in structure, these manual graters are inconvenient to use, have low grating efficiency, and pose a risk of injury, especially with smaller pieces of ginger and garlic. Holding the ginger and garlic while sliding it across the holes is difficult, and fingers can easily come into contact with the holes and be pricked. Chinese Patent Publication No. CN215202202U discloses a "novel grating knife-shaped vegetable cutter," which features a grating knife-shaped tube with serrated edges and through holes on its surface. During use, the grating knife-shaped tube rotates, using the serrated edges to grate and cut the food into a paste or slurry. This grating knife-shaped tube uses a metal body, which is prone to blade rolling. To prevent this, a reinforcing layer is needed, resulting in a complex tube structure and high manufacturing difficulty. Summary of the Invention

[0004] 1. Technical problem to be solved by the utility model

[0005] The purpose of this invention is to overcome the aforementioned shortcomings of existing grating blades and to provide a grating blade and a grater with the grating blade. Using the technical solution of this invention, the grating teeth repeatedly crush and grind the food ingredients. The discharge port in front of the grating teeth guides the ground ingredients into the inner side of the blade. Because the width of the tooth block near the corresponding discharge port is greater than the width of the opposite side, the tooth block structure has high strength and can bluntly crush the food ingredients, resulting in fine and efficient grinding. The ground ingredients are concentrated on the front side of the grating teeth and can be quickly discharged through the discharge port, making discharge fast and convenient. Furthermore, the entire grating blade has a simple structure, is easy to manufacture, can be used in existing drum food processors, and is safe and reliable to operate.

[0006] 2. Technical Solution

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0008] The present invention provides a grinding blade cylinder, comprising a blade cylinder body, wherein a plurality of grinding teeth extending along the front-back direction of the blade cylinder body are distributed circumferentially on the outer cylinder wall of the blade cylinder body, and a discharge port located near the rotation direction of each grinding tooth. Each grinding tooth is composed of a plurality of tooth blocks arranged thereon, wherein the width of the tooth block on the side near the corresponding discharge port is greater than the width on the opposite side.

[0009] Furthermore, the grinding teeth are arranged in a spiral shape on the outer wall of the main body of the blade cylinder, and the spiral angle of the grinding teeth is 35° to 45°, and the individual tooth blocks in two adjacent grinding teeth are staggered.

[0010] Furthermore, the tail of the blade body is provided with a rotating locking structure. The rotation locking direction of the rotating locking structure is opposite to the rotation direction of the blade body. The resistance of the food to the grinding teeth in the rotation direction has an axial rearward component.

[0011] Furthermore, the rotary engagement structure includes a drive shaft hole coaxially disposed at the tail end of the cutter barrel body and a drive rib disposed within the drive shaft hole, and the front opening of the cutter barrel body has an outer ring body.

[0012] Furthermore, the outer wall of the main body of the cutter barrel is a straight cylinder or a conical cylinder, and the discharge port is a strip-shaped opening arranged along the grinding teeth.

[0013] Furthermore, the grinding blade barrel is manufactured using a one-piece injection molding process.

[0014] Furthermore, the toothed block has a triangular tooth structure. The toothed block has a grinding cutting edge on the side near the corresponding discharge port. The front side of the grinding cutting edge has a front cutting face, and the rear side of the grinding cutting edge has a main back cutting face. The front cutting face and the main back cutting face are connected to form a secondary back cutting face. The top of the toothed block has a tooth tip. The projections of the roots of the front cutting face, the main back cutting face, and the secondary back cutting face onto the outer wall of the main body of the cutter barrel are approximately triangular.

[0015] Furthermore, the length L1 of the root projection line of the rake face is approximately half the length L2 of the root projection line of the main flank face; the angle α between the root projection line of the main flank face and the cross-sectional projection of the tool barrel body is 3° to 5°; the angle b between the root projection line of the rake face and the root projection line of the main flank face is 40° to 45°; and the angle c between the root projection line of the rake face and the axial section projection of the tool barrel body is 40° to 45°.

[0016] Furthermore, both the grinding cutting edge and the tooth tip have a blunt cutting edge structure.

[0017] The present invention provides a grater with the aforementioned grating blade cylinder. The grater includes an outer cylinder capable of accommodating the grating blade cylinder and a drive mechanism capable of rotating the grating blade cylinder. The outer cylinder is also provided with a feeding cylinder that is positioned opposite to the grating teeth on the grating blade cylinder.

[0018] 3. Beneficial effects

[0019] Compared with existing known technologies, the technical solution provided by this utility model has the following beneficial effects:

[0020] (1) The present invention provides a grinding blade tube, which includes a blade tube body. The outer wall of the blade tube body is circumferentially distributed with several grinding teeth extending along the front-back direction of the blade tube body and a discharge port located near the rotation direction of each grinding tooth. Each grinding tooth is composed of several tooth blocks. The width of the tooth block on the side near the corresponding discharge port is greater than the width on the opposite side. The tooth blocks of the grinding teeth repeatedly crush and grind the food. The discharge port in front of the grinding teeth can guide the ground food into the inner side of the blade tube. Since the width of the tooth block on the side near the corresponding discharge port is greater than the width on the opposite side, the tooth block structure has high strength and can bluntly crush the food. The grinding is delicate and efficient. The ground food is concentrated on the front side of the grinding teeth and can be quickly discharged through the discharge port. The discharge is fast and convenient. In addition, the entire grinding blade tube has a simple structure and is easy to manufacture. It can be used in existing drum food processors and is safe and reliable to operate.

[0021] (2) A grinding blade of the present invention has grinding teeth arranged in a spiral shape on the outer wall of the blade body. The spiral angle of the grinding teeth is 35° to 45°, and the teeth in two adjacent grinding teeth are staggered. The grinding teeth arranged in a spiral shape have less resistance, which helps to reduce the working resistance of the grinding blade. The staggered teeth can repeatedly crush the food, which improves the grinding effect.

[0022] (3) A grating knife barrel of the present invention has a rotating locking structure at the tail of the main body of the knife barrel. The rotation locking direction of the rotating locking structure is opposite to the rotation direction of the main body of the knife barrel. The resistance of the food to the grating teeth in the rotation direction has an axial rearward component. The rotating locking structure design facilitates the installation of the knife barrel and the rotation drive. The rotation direction design of the grating teeth can further ensure the installation and transmission stability of the grating knife barrel.

[0023] (4) A grinding knife barrel of the present invention has a rotating locking structure including a drive shaft hole coaxially disposed at the tail of the main body of the barrel and a drive rib disposed in the drive shaft hole. The front opening of the main body of the barrel has an outer ring body. The grinding knife barrel has a simple structure, is easy to manufacture, has better overall strength, and has a long service life.

[0024] (5) The grating blade of this utility model has an outer cylindrical wall that is straight or conical, which can meet the needs of different drum food processors; the discharge port is a strip-shaped opening set along the grating teeth, which allows for smooth discharge and has little impact on the strength of the entire grating blade.

[0025] (6) The grinding knife barrel of this utility model is made by one-piece injection molding process, which is simple and convenient to manufacture and has a lower manufacturing cost.

[0026] (7) A grinding knife barrel of the present invention has a triangular tooth structure. The tooth block has a grinding cutting edge on the side near the corresponding discharge port. The front side of the grinding cutting edge has a front cutting surface, and the rear side of the grinding cutting edge has a main back cutting surface. The front cutting surface and the main back cutting surface are connected to form a secondary back cutting surface. The top of the tooth block has a tooth tip. The projection of the root of the front cutting surface, the root of the main back cutting surface and the root of the secondary back cutting surface on the outer wall of the main body of the knife barrel is roughly triangular. The triangular tooth structure is simple and the grinding is easy and efficient.

[0027] (8) A grinding cutter barrel of the present invention has a root projection line length L1 of the rake face that is approximately half the root projection line length L2 of the main flank face. The angle a between the root projection line of the main flank face and the cross-sectional projection of the barrel body is 3° to 5°. The angle b between the root projection line of the rake face and the root projection line of the main flank face is 40° to 45°. The angle c between the root projection line of the rake face and the axial section projection of the barrel body is 40° to 45°. The rake face has a certain cutting angle. The main flank face and the secondary flank face form a negative angle in the rotational cutting direction. This design can reduce grinding resistance and improve grinding efficiency while ensuring grinding effect.

[0028] (9) The grinding blade of this utility model has a blunt edge structure for both the grinding blade and the tooth tip. On the one hand, this makes the tooth block structural strength higher and the wear resistance better. On the other hand, the blunt crushing has a better crushing and peeling effect on the food, and the grinding is uniform and delicate.

[0029] (10) A grinder with the above-mentioned grinding blade cylinder of the present invention includes an outer cylinder body capable of accommodating the grinding blade cylinder and a drive mechanism capable of driving the grinding blade cylinder to rotate. The outer cylinder body is also provided with a feeding cylinder opposite to the grinding teeth on the grinding blade cylinder. The grinding effect is achieved by using a roller structure, which is convenient to use and has high safety. Attached Figure Description

[0039] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0040] [Example]

[0041] Combination Figures 1 to 7As shown, a grinding blade cylinder of this embodiment includes a cylinder body 1 with an open front end. The outer wall of the cylinder body 1 has several grinding teeth 2 extending along the front-rear direction of the cylinder body 1, and a discharge port 3 located near the rotation direction of each grinding tooth 2. Each grinding tooth 2 is composed of several tooth blocks 2A arranged in a row. The width of the tooth block 2A near the corresponding discharge port 3 is greater than the width of the opposite side. The grinding teeth 2 form a row of scraping teeth on the cylinder body 1, and the discharge port 3 is located in front of each grinding tooth 2. During the grinding process, the ingredients are pressed against the outer wall of the blade body 1. The blade body 1 rotates in the direction of rotation, and the front side of the grinding teeth 2 contacts the ingredients first, crushing them. Most of the separated ingredients gather on the front side of the grinding teeth 2 and enter the inner side of the blade body 1 through the discharge port 3, finally exiting from the open side of the blade body 1. As the blade body 1 rotates, each grinding tooth 2 repeatedly breaks and crushes the ingredients, forming a uniform and fine paste. Because the width of the tooth block 2A on the side closest to the corresponding discharge port 3 is greater than the width on the opposite side, the tooth block 2A has high structural strength and can bluntly crush the ingredients, resulting in a fine and efficient grinding process. The ground paste is concentrated on the front side of the grinding teeth 2 and can be quickly discharged through the discharge port 3, making discharge fast and convenient. Furthermore, the entire grinding blade body has a simple structure, is easy to manufacture, can be used in existing drum food processors, and is safe and reliable to operate.

[0042] Reference Figures 1 to 6 As shown, in this embodiment, the aforementioned grinding teeth 2 are spirally arranged on the outer wall of the blade body 1. The spiral angle of the grinding teeth 2 is preferably 35° to 45°, and the tooth blocks 2A in adjacent grinding teeth 2 are staggered. Specifically, in this embodiment, six grinding teeth 2 are evenly arranged on the outer wall of the blade body 1, and the tooth blocks 2A in adjacent grinding teeth 2 are staggered. The spirally arranged grinding teeth 2 experience less resistance, which helps reduce the working resistance of the grinding blade. The staggered tooth blocks 2A can repeatedly crush the food, improving the grinding effect. Figure 1 , Figure 3 and Figure 5As shown, the tail 4 of the aforementioned blade body 1 is equipped with a rotary locking structure. The rotation locking direction of the rotary locking structure is opposite to the rotation direction of the blade body 1, ensuring that the rotary locking structure can automatically lock during the rotation of the blade body 1 in its rotation direction. This facilitates the installation of the blade and the rotation drive, ensuring the stability of the connection and transmission. Furthermore, the resistance of the food material to the grating teeth 2 in the rotation direction has an axial rearward component, causing the grating blade to have a certain tendency to move backward during operation, further ensuring the installation and transmission stability of the grating blade. Specifically, the rotary locking structure includes a drive shaft hole 5 coaxially located at the tail 4 of the blade body 1 and a drive rib 6 located within the drive shaft hole 5. The front opening of the blade body 1 also has an outer ring 7. This grating blade has advantages such as simple structure, ease of manufacture, better overall strength, and long service life.

[0043] This embodiment provides a grater / shredder, the outer wall of which is either straight or conical, making it suitable for both straight and conical drum food processors to accommodate different types of food processors. The straight-cylinder type is cylindrical with approximately the same diameter at the front and back; the conical type can be wider at the front and narrower at the back, or vice versa. Figure 5 The cone-shaped cutter barrel shown has a large diameter at the front end and a small diameter at the rear end; the value of its taper ω can be determined according to requirements. For example... Figure 4 As shown, the discharge port 3 is a strip-shaped opening set along the grinding teeth 2. One side of the discharge port 3 is close to the front side of the rotation direction of the grinding teeth 2, which facilitates the discharge of the ground ingredients and ensures smooth discharge. Moreover, the strip-shaped discharge port 3 has little impact on the strength of the entire grinding cylinder.

[0044] Preferably, the grinding blade barrel of this embodiment is manufactured using an integral injection molding process, which is simpler and more convenient to manufacture and has a lower manufacturing cost compared to existing metal barrel structures.

[0045] The aforementioned tooth block 2A preferably adopts a triangular tooth structure. See details... Figure 7As shown, the toothed block 2A has a grinding blade 2-1 on the side near the corresponding discharge port 3. The grinding blade 2-1 is located at the front of the entire toothed block 2A (along the rotation direction). The front side of the grinding blade 2-1 has a front cutting surface 2-2, which is used to guide and separate the crushed food. The food cut by the grinding blade 2-1 is further separated by the front cutting surface 2-2 and guided towards the grinding blade 2-1 of the adjacent toothed block 2A, thereby achieving better crushing of the food. The rear side of the grinding blade 2-1 has a main rear cutting surface 2-3. The front cutting surface 2-2 and the main rear cutting surface 2-3 are connected to form a secondary rear cutting surface 2-4. The top of the toothed block 2A has a tooth tip 2-5. The projections of the roots of the front cutting surface 2-2, the main rear cutting surface 2-3, and the secondary rear cutting surface 2-4 onto the outer wall of the main body 1 of the blade barrel are approximately triangular. The above-mentioned triangular tooth structure is simple in structure and makes grinding easy and efficient. Furthermore, the length L1 of the root projection line of the rake face 2-2 is approximately half the length L2 of the root projection line of the main flank face 2-3. The angle α between the root projection line of the main flank face 2-3 and the cross-sectional projection of the tool barrel body 1 is 3° to 5°, the angle b between the root projection line of the rake face 2-2 and the root projection line of the main flank face 2-3 is 40° to 45°, and the angle c between the root projection line of the rake face 2-2 and the axial section projection of the tool barrel body 1 is 40° to 45°. Thus, the rake face 2-2 has a certain cutting angle, and the main flank face 2-3 and the secondary flank face 2-4 form a negative angle in the rotational cutting direction. This design can reduce grinding resistance and improve grinding efficiency while ensuring grinding effect. In addition, both the grinding cutting edge 2-1 and the tooth tip 2-5 are preferably blunt-edged structures, such as... Figure 7 As shown, the grinding blade 2-1 can have a certain width, and the tooth tip 2-5 can be flat. On the one hand, this makes the structure of the tooth block 2A stronger and more wear-resistant. On the other hand, the blunt crushing has a better crushing and peeling effect on the food, resulting in a more uniform and delicate grinding.

[0046] This embodiment also discloses a grinder with the aforementioned grinding blade cylinder. The grinder includes an outer cylinder capable of housing the grinding blade cylinder and a drive mechanism capable of rotating the grinding blade cylinder. The outer cylinder also has a feeding cylinder positioned opposite the grinding teeth 2 on the grinding blade cylinder. The drive mechanism can be electric or manual. In use, the ingredients to be ground (such as ginger and garlic) are placed into the feeding cylinder, and a presser is used to press the ingredients down. The drive mechanism rotates the grinding blade cylinder, and the grinding teeth 2 on the grinding blade cylinder crush and grind the ingredients. The resulting paste enters the inside of the blade cylinder through the discharge port 3 and exits from the open front end. The grinding action is achieved using a roller structure, making it convenient and safe to use. The aforementioned grinding blade cylinder can be matched with existing roller-type vegetable cutters to form a grinding roller-type vegetable cutter, further enriching the functionality of existing products.

[0047] This utility model discloses a grater and a grater with the grater. The grater and the grater teeth repeatedly crush and grind the food. The discharge port in front of the grater teeth guides the ground food into the inner side of the grater. Because the width of the tooth block near the corresponding discharge port is greater than the width of the opposite side, the tooth block has high structural strength and can bluntly crush the food, resulting in fine and efficient grating. The ground food is concentrated on the front side of the grater teeth and can be quickly discharged through the discharge port, making discharge fast and convenient. Furthermore, the entire grater has a simple structure, is easy to manufacture, can be used in existing drum food processors, and is safe and reliable to operate.

[0048] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
