Description

Technical Field

[0001] This invention belongs to the technical field of kitchenware, specifically relating to a flat dicing cutter. Background Technology

[0002] In home cooking and food processing, dicing ingredients is a common pre-processing step. Traditional dicing usually relies on manual operation with a knife, which is not only inefficient but also makes it difficult to achieve uniform cuts and requires a high level of knife skills from the operator.

[0003] Most existing dicing tools are complex in structure and expensive. To reduce costs, flat dicing tools based on flat vegetable cutters have appeared on the market. For example, Chinese utility model patent CN204976764U (publication date: 2016.01.20) discloses a multi-functional manual dicing tool for home use. This multi-functional manual dicing tool for home use includes a blade body, characterized by: a rotating shaft installed at the rear of the blade body, a roller mounted on the rotating shaft, several slicing blades evenly mounted on the outer side of the roller, several strip-cutting blades evenly mounted at the front of the blade body, and a cutting blade installed in front of the strip-cutting blades. In use, fruits and vegetables are pushed forward from the rear of the blade body, causing the fruits and vegetables to push the roller to rotate around the rotating shaft. The bottom surface of the fruits and vegetables is cut horizontally downwards by the slicing blades that extend from the blade body. Then, as the fruits and vegetables continue to be pushed forward, they are cut vertically downwards by the strip-cutting blades. Finally, the cutting blade separates the cut-to-a-depth portion from the uncut portion, thus creating diced pieces.

[0004] The shortcomings of the aforementioned manual dicing machine are: its rollers are passively rotated by the food ingredients, lacking an active drive structure. When the food ingredients drive the rollers, it relies on the friction between the food ingredients and the rollers. When the food surface is slippery or soft, the friction is insufficient to drive the rollers to rotate, causing the rollers to jam and frequently slip, resulting in uneven cutting. In addition, because the cutting stations are independent of each other and are far apart, the food ingredients are prone to deformation during feeding, making it impossible to cut uniform diced ingredients. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by providing a flat dicing cutter that has the advantages of simple structure, convenient use, and low cost, and also provides smooth, stable, and uniform cutting.

[0006] To solve the above-mentioned technical problems, the objective of this invention is achieved through the following technical solution: A flat dicing cutter, comprising: A substrate, wherein a cutting station is provided on the substrate; The first cutting tool is located on one side of the cutting station and has multiple vertical cutting edges. The second cutting tool is located on the other side of the cutting station and has a horizontal cutting edge. The third cutter includes a roller rotatably connected to the substrate. The outer periphery of the roller is provided with a plurality of radially extending rotating blades, and the ends of the rotating blades are provided with rotating cutting edges. The third cutter is located below the cutting station, and the rotating cutting edges cooperate with the bottom plane of the second cutter to cut the food. Hand guard, the hand guard is used to fix the food and slide along the length direction of the substrate, the food is pushed by the hand guard to pass through the first cutter, the second cutter and the third cutter in sequence and cut into diced shape; The hand guard is connected to the roller drive. When the hand guard pushes the food to feed, it drives the roller to rotate. When the roller rotates, the linear speed of the rotating cutting edge is greater than the moving speed of the hand guard.

[0007] As a further improvement of the present invention, the ratio of the linear velocity of the rotating cutting edge to the moving speed of the handguard is 1.05-1.20:1. In the present invention, the magnitude of the linear velocity of the rotating cutting edge is equal to the product of the angular velocity of the drum and the rotation radius of the rotating cutting edge (i.e., the radial distance from the center of the drum to the rotating cutting edge).

[0008] As a further improvement of the present invention, the two sides of the hand guard extend downward to form sliding portions, the inner sidewall of the sliding portion slides in conjunction with the outer sidewall of the substrate, the lower surface of the sliding portion is provided with a rack extending along the sliding direction, the two ends of the roller extend out of the substrate and are fitted with gears, and the rack meshes with the gears for transmission.

[0009] As a further improvement of the present invention, the substrate includes a first panel and a second panel fixed to different horizontal planes, the upper surface of the first panel is lower than the upper surface of the second panel, the cutting station is formed between the first panel and the second panel, the first cutter is fixed to the first panel, the second cutter is fixed to the second panel, and the third cutter is located below the cutting station; the food is fed along the direction from the first panel toward the second panel.

[0010] As a further improvement of the present invention, a stripping sleeve is movably fitted on the roller, the inner diameter of the stripping sleeve is larger than the outer diameter of the roller, and the stripping sleeve is eccentrically fitted with the roller; in the present invention, the movable fitting means that the stripping sleeve is radially movable relative to the roller.

[0011] As a further improvement of the present invention, the stripping sleeve includes an end ring and stripping bars. The stripping bars extend axially along their length direction, and their two ends are integrated with the end ring. The material-accepting gaps between the stripping bars and the rotating blades correspond one-to-one, and the rotating blades pass through the gaps between the stripping bars. Preferably, the circumferential dimension of the stripping bars is smaller than the circumferential dimension of the roller corresponding to the material-accepting gap, and the diameter difference between the stripping sleeve and the roller is smaller than the radial dimension of the rotating blades.

[0012] As a further improvement of the present invention, the roller includes a multi-faceted shaft, on which a blade mounting seat, a bushing and the gear are mounted. The blade mounting seat has a blade mounting groove for mounting a rotating blade, and the bushing is rotatably connected to a shaft hole on the base plate.

[0013] As a further improvement of the present invention, the blade mounting groove is an axially penetrating through groove, the end of the rotating blade is provided with a blade fixing part extending out of the blade mounting groove, a blade fixing sleeve is fitted on the polygonal shaft, and a fixing groove is provided on the blade fixing sleeve for the blade fixing part to be inserted.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention provides a flat dicing cutter. By setting a transmission connection between the handguard and the roller, the roller obtains active driving force, solving the slippage and jamming problems caused by the roller's passive rotation relying on the friction of food in the prior art. Regardless of whether the food surface is smooth or the texture is soft, the roller can obtain stable driving force, and the cutting process is smooth and reliable.

[0015] 2. This invention adjusts the cutting structure and cutting sequence, concentrating all three blades at the same cutting station. The food is continuously fed as it passes through the three blades, first vertically, then horizontally, and finally cut off. This avoids the food deformation problem caused by the independent cutting stations and large intervals between them, resulting in high granule regularity and good uniformity.

[0016] 3. Due to the unavoidable assembly gap between the bottom planes of the third and second blades, a very thin residual layer may be generated at the bottom when the third blade cuts the food. This invention addresses this by ensuring the linear speed of the rotating cutting edge is greater than the speed of the handguard. This causes the rotating cutting edge to apply a pulling force along the rotation direction of the roller to the remaining connecting tissue at the bottom of the food as it passes the cutting station, forcibly breaking off this connecting tissue. Because this pulling force only acts on the very thin residual layer at the bottom of the food, it does not impact or damage the main body of the food, achieving thorough and smooth dicing and separation, resulting in clean, burr-free, and tailless diced pieces.

[0017] 4. By setting a stripping sleeve that is eccentrically matched with the drum, the material holding gaps between the stripping strip and the rotating blade correspond one-to-one. The rotating blade passes through the gap between the stripping strip. As the drum rotates, the stripping strip gradually moves outward relative to the bottom of the material holding gap, pushing the material held in the material holding gap outward. Finally, when the stripping strip rotates to the bottom, the material is forcibly detached, effectively preventing the cut material from getting stuck in the gap of the rotating blade and ensuring the smooth progress of continuous cutting operations.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-5 : This invention discloses a flat dicing tool, comprising a base plate 1, a first blade 2, a second blade 3, a third blade 4, and a handguard 5. The base plate 1 is a flat structure and serves as the supporting foundation for the entire dicing tool. The first blade 2, second blade 3, and third blade 4 are all mounted on the base plate 1. The handguard 5 is detachably connected to the base plate 1, and after connection, the handguard 5 is slidably positioned above the base plate 1 to fix the food to be diced and to push it along the length of the base plate 1. A cutting station 11 is provided on the substrate 1. In this embodiment, the substrate 1 includes a first panel 12 and a second panel 13. The first panel 12 and the second panel 13 are fixed on different horizontal planes. The upper surface of the first panel 12 is lower than the upper surface of the second panel 13. The food is fed along the first panel 12 toward the second panel 13. A cutting station 11 is formed between the first panel 12 and the second panel 13.

[0020] The first cutter 2 is located on one side of the cutting station 11 and is fixedly installed on the first panel 12. The first cutter 2 has multiple vertical cutting edges 21, which are evenly spaced along the width direction of the substrate 1. The vertical cutting edges 21 are used to cut the food along the feeding direction during the food feeding process; the spacing between the vertical cutting edges determines the width of the food.

[0021] The second cutter 3 is located on the other side of the cutting station 11 and is fixedly mounted on the second panel 13. The second cutter 3 has a horizontal cutting edge 31, which extends along the width direction of the substrate 1 and is used to cut the food material formed by the first cutter 2 in a horizontal direction. The height difference between the horizontal cutting edge 31 and the first panel 12 determines the thickness of the food material.

[0022] The third cutter 4 includes a roller 41 and a plurality of rotating blades 42 disposed on the outer circumferential surface of the roller 41. The roller 41 is rotatably connected to the substrate 1, and its axis of rotation is perpendicular to the feeding direction of the food and parallel to the width direction of the substrate 1. Each rotating blade 42 extends radially outward along the roller 41, and the end of the rotating blade 42 is provided with a rotating cutting edge 43. The third cutter 4 is located below the cutting station 11, and the rotating cutting edge 43 extends out from the cutting station 11. The rotating cutting edge 43 cooperates with the bottom plane of the second cutter 3 to cut the food. Specifically, the movement trajectory of the rotating cutting edge 43 forms a shearing engagement with the bottom plane of the second cutter 3, and the spacing of the rotating cutting edges 43 determines the length of the food cuttings.

[0023] Handle 5 is used to hold the food to be cut and slides along the length of the substrate 1. In use, the user presses the food onto the substrate 1 using handle 5. The food is pushed by handle 5 through the first cutter 2, the second cutter 3 and the third cutter 4 in sequence, and is then cut into cubes.

[0024] The handguard 5 is connected to the roller 41 via a transmission structure. Specifically, the two sides of the handguard 5 extend downward to form sliding portions 51. The inner sidewall of the sliding portion 51 slides against the outer sidewall of the substrate 1, allowing the handguard 5 to slide stably along the length of the substrate 1. A rack 52 extending along the sliding direction is provided on the lower surface of the sliding portion 51. Both ends of the roller 41 extend beyond the outer side of the substrate 1, and gears 411 are fitted at the extended ends. The rack 52 and the gears 411 mesh with each other. When the handguard 5 slides along the substrate 1, the rack 52 drives the gears 411 to rotate, and the gears 411 drive the roller 41 to rotate synchronously. Through the above transmission structure, the handguard 5 drives the roller 41 to rotate actively when pushing the food feed.

[0025] The transmission structure is designed so that when the roller 41 rotates, the linear velocity of the rotating cutting edge 43 is greater than the moving speed of the handguard 5. In this embodiment, the ratio of the linear velocity of the rotating cutting edge 43 to the moving speed of the handguard 5 is 1.05 to 1.20:1. This speed ratio is determined by the transmission ratio of the rack 52 and the gear 411, as well as the rotation radius of the rotating cutting edge 43, ensuring sufficient pulling force to sever any remaining connecting tissue at the bottom of the food while avoiding damage to the food due to excessive speed difference.

[0026] The working process of the flat dicing device of the present invention is as follows: The user secures and presses the food ingredients by holding the handle 5 in place. Pushing the handle 5 forward causes the food ingredients to move along the first panel 12 towards the second panel 13. During this forward movement, the rack 52 on the handle 5 drives the gear 411 to rotate, which in turn drives the roller 41 to rotate.

[0027] The food first passes through the first cutter 2. Multiple vertical cutting edges 21 of the first cutter 2 longitudinally cut the food along the feed direction, creating a longitudinal cut at the bottom. Then, the food enters the second cutter 3. The horizontal cutting edges 31 of the second cutter 3 transversely cut along the width of the substrate 1, cutting the food into separate strips. Finally, the food enters the third cutter 4, which rotates from bottom to top, cutting the food into n-shaped pieces at intervals along the feed direction. Due to an unavoidable assembly gap between the rotating cutting edges 43 of the second cutter 3 and the third cutter 4, the rotating cutting edges 43 cannot achieve a zero-gap fit with the bottom plane of the second cutter 3. If the moving speed of the guard 5 (i.e., the food) is the same as the linear speed of the rotating cutting edges 43, the bottom of the food is difficult to completely cut off by the third cutter 4.

[0028] In this embodiment, however, because the linear velocity of the rotating cutting edge 43 is greater than the linear velocity of the handguard 5, when the food enters the station of the third cutter 4, the rotating cutting edge 43 passes through the cutting station 11 at a linear velocity greater than the feed speed. During this process, the speed difference between the two applies a pulling force along the rotation direction of the roller 41 to the connecting tissue remaining at the bottom of the block. This pulling force forcibly breaks the connecting tissue remaining at the bottom, causing the food to be completely separated into individual small pieces.

[0029] In another preferred embodiment of this invention, to prevent the cut granules from getting stuck in the gaps between the rotating blades 42, a stripping sleeve 44 is movably fitted onto the roller 41. The inner diameter of the stripping sleeve 44 is larger than the outer diameter of the roller 41, and the stripping sleeve 44 is eccentrically fitted to the roller 41. The stripping sleeve 44 includes two end rings 441 and a plurality of stripping strips 442 connected between the two end rings 441. The stripping strips 442 extend along the axial direction of the roller 41, and their two ends are respectively integrated with the end rings 441. Each stripping strip 442 corresponds one-to-one with the material-accommodating gap 421 between each rotating blade 42, and the rotating blades 42 pass through the gaps between adjacent stripping strips 442.

[0030] The working process of the stripper sleeve 44 is as follows: When the drum 41 rotates, the stripper strip 442 moves radially relative to the material holding gap 421 under the action of eccentric fit and material extrusion, pushing out the material stuck in the material holding gap 421, preventing the material from getting stuck in the material holding gap 421, and ensuring the smooth progress of continuous cutting operation.

[0031] Preferably, the circumferential dimension of the stripping bar 442 is smaller than the circumferential dimension of the roller 41 corresponding to the material holding gap 421, and the diameter difference between the stripping sleeve 44 and the roller 41 is smaller than the radial dimension of the rotating blade 42, so as to ensure that the stripping sleeve 44 can push the pellets during rotation without interfering with the rotating blade 42 or detaching from the sleeve.

[0032] In this embodiment, the specific assembly structure of the third cutter 4 is as follows: the roller 41 includes a multi-faceted shaft 412. A blade mounting seat 413, two bushings 414, and two gears 411 are mounted on the multi-faceted shaft 412. The two gears 411 are respectively mounted on both ends of the multi-faceted shaft 412 for meshing with the rack 52 on the handguard 5; the two bushings 414 are located inside the gears 411 and are rotatably connected to the shaft holes 14 opened on the base plate 1, allowing the roller 41 to rotate freely relative to the base plate 1; the blade mounting seat 413 is located between the two bushings 414 and has a blade mounting groove 415 for mounting the rotating blade 42.

[0033] The blade mounting groove 415 is an axially penetrating through groove, and its number is the same as the number of rotating blades 42. Each rotating blade 42 is installed in its corresponding blade mounting groove 415, and a blade fixing part 422 is provided at the end of the rotating blade 42, which extends out of the blade mounting groove 415.

[0034] A blade fixing sleeve 416 is also fitted onto the polygonal shaft 412. The blade fixing sleeve 416 has a fixing groove 417 for the blade fixing part 422 to be inserted. When installing the rotating blade 42, first insert the rotating blade 42 into the blade mounting groove 415, and then put the blade fixing sleeve 416 onto the polygonal shaft 412, so that the blade fixing part 422 is inserted into the fixing groove 417, thereby fixing the rotating blade 42 axially and circumferentially. With the above structure, the rotating blade 42 can be stably installed on the roller 41, ensuring that the blade does not loosen or shift during the cutting process.

[0035] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
