Description

Technical Field

[0001] This invention relates to the field of dicing machine technology, specifically a carrot dicing machine and dicing method based on a change of direction. Background Technology

[0002] Carrots, as a nutritious and widely consumed root vegetable, often need to be processed into small pieces of specific shapes and sizes in the catering industry, food processing industry, and home kitchens. The existing methods for cutting carrots mainly use rotary cutting equipment, namely dicing machines. The typical working principle is as follows: the carrots are fed into a high-speed rotating cylindrical structure. The inner wall or outer side of the cutting cylinder is equipped with a fixed blade matrix. Under the drive of gravity, friction, or a propeller, the carrots pass through the rotating cutting cylinder in a roughly straight line.

[0003] Although such equipment improves production efficiency, it still has the following technical limitations: (1) Single and fixed cutting direction: The cutting trajectory of the blade and the feeding direction of the carrot are relatively fixed single linear motion (axial or radial); (2) Unable to generate diverse / irregular shapes: Existing equipment cannot dynamically change the relative motion direction of the cutter or the feeding direction of the carrot during the cutting process, and cannot produce non-cubic shaped blocks such as polygons or irregular polyhedra; (3) Unsatisfactory material utilization: When processing irregular or slightly curved carrots, the straight cutting mode generates a large amount of scrap or irregular scrap at the cutting end or edge, resulting in waste of raw materials; (4) Limited applicable raw material shapes: It cannot effectively process carrots that are too curved, have too large a taper, or have irregular shapes; (5) Single blade contact method and cutting surface: The blade's effect on the carrot is mainly a single cut or extrusion cut perpendicular to its feeding direction, lacking multi-angle and multi-directional cutting combinations.

[0004] In summary, the fundamental challenge faced by existing rotary cutting equipment in processing carrot chunks lies in its fixed motion trajectory and single cutting direction. There is a lack of multi-dimensional, controllable, and variable-direction relative motion between the cutting blade assembly and the material. To address this, we provide a carrot chunking machine and cutting method based on variable direction to solve the aforementioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a carrot dicing machine and dicing method based on direction change, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

Fish scale rollers are fixed on the first rotating rollers, and rotating rollers are fixed on the second rotating rollers. Connecting plates are provided at the ends of the first and second rotating rollers, and the two ends of the connecting plates are rotatably connected to the first and second rotating rollers, respectively. The two first rotating rollers are driven to rotate synchronously in opposite directions by a first transmission mechanism. The first and second rotating rollers are driven synchronously in opposite directions by a first gear mechanism. A fourth cylinder is hinged on the frame, and the piston rod at the output end of the fourth cylinder is hinged to the connecting plate.

[0018] The first transmission mechanism includes a third gear fixed on two first rotating rollers and a fourth gear rotatably mounted on a frame. A fifth motor is fixed on the frame, and a fifth gear is fixed at the output end of the fifth motor. The fifth gear meshes with the fourth gear and one of the third gears, and the fourth gear also meshes with the other third gear.

[0019] The first gear mechanism includes a first gear fixed on the second roller and a second gear fixed on the first roller, wherein the first gear meshes with the second gear.

[0020] As described above, a carrot dicing machine based on reversible direction is described: the feeding mechanism includes two rollers rotatably mounted on the frame, the outer circumference of the rollers is coupled with a conveyor belt, a sixth motor is fixed on the frame, and one of the rollers is mounted on the output end of the sixth motor and driven to rotate by the sixth motor.

[0021] A carrot dicing method based on a direction-changing carrot dicing machine includes the following steps:

[0022] S1, the carrots are fed from the trough into the inside of the cylinder by the feeding mechanism. The pusher plate moves through the pushing mechanism to push the carrots in the cylinder to the port of the cylinder. The pneumatic clamp is activated to clamp the carrots at the port.

The rotation angle of the carrots in the cylinder can be adjusted by rotating the cylinder through the first rotating mechanism, and the pitch angle of the carrots can be adjusted by tilting the movable frame through the first pitch mechanism. Thus, the present invention can change the orientation and direction of the carrot segments in the cylinder in three-dimensional space, and actively adjust the posture and contact direction of the carrots relative to the high-speed rotating blades.

[0027] In addition, the fourth motor can change the tilt angle of the blade by rotating through the second rotating mechanism. Together with the adjustment seat moving through the guide rail mechanism to drive the blade to move, and the tilting frame adjusting the tilt of the blade through the second tilting mechanism, the action of the blade adjusting the tilt of the carrot can change the cutting angle of the carrot.

[0028] This invention achieves multi-dimensional dynamic directional cutting by designing independent and precise control over rotation and pitch, and incorporating these degrees of freedom into the cutting and material feeding modules. This completely breaks the limitation of traditional equipment's single-direction cutting, making the spatial relative motion trajectory between the blade and the material highly flexible. It can be used to cut carrots into blocks with more diverse raw material shapes, such as slightly curved carrots, resulting in a closer cut, reduced waste, and improved material utilization. At the same time, it can be used to cut carrot blocks into diverse and complex geometric shapes, meeting the industry's processing needs for novel pre-formed carrots. Attached Figure Description

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0042] Please see Figures 1 to 11 As an embodiment of the present invention, a carrot cutting machine based on direction change includes a frame 1, on which a material direction change module and a cutting direction change module are provided;

[0043] The material reversing module includes a movable frame 2 hinged to the frame 1 at one end, a material cylinder 3 rotatably mounted on the movable frame 2, a slot 4 opened on the material cylinder 3, a push plate 6 movably engaged inside the material cylinder 3, the push plate 6 moves through a pushing mechanism, the material cylinder 3 rotates through a first rotating mechanism, a pneumatic clamp 7 is fixed at the end of the material cylinder 3, and the movable frame 2 is tilted and adjusted through a first pitching mechanism.

[0044] The cutting direction-changing module includes an adjustment seat 14, which moves via a guide rail mechanism. A pitch frame 18 is provided above the adjustment seat 14. The pitch frame 18 is tilted and adjusted via a second pitch mechanism. A fourth motor 22 is provided at the end of the pitch frame 18. A third rotating shaft 23 is fixed to the output end of the fourth motor 22. A blade 24 is mounted on the third rotating shaft 23. The fourth motor 22 rotates via a second rotating mechanism.

[0045] The frame 1 is equipped with a feeding mechanism for conveying carrots into the material cylinder 3 and a feeding mechanism for conveying the chopped carrots outward.

[0046] In this embodiment, during use, carrots are sequentially fed from the slot 4 into the cylinder 3 via the feeding mechanism. The pusher plate 6 moves via the pushing mechanism to push the carrots in the cylinder 3 to the port of the cylinder 3. The pneumatic clamp 7 is activated to clamp the carrots at the port. The grippers of the pneumatic clamp 7 are arc-shaped and adapted to the outer shape of the carrots. The cylinder 3 can be rotated by the first rotating mechanism to adjust the rotation angle of the carrots inside the cylinder 3. The movable frame 2 can be tilted by the first pitch mechanism to adjust the pitch angle of the carrots. Thus, the orientation and direction of the carrot segments in the cylinder 3 can be changed in three-dimensional space, and the posture and contact direction of the carrots relative to the high-speed rotating blade 24 can be actively adjusted. The fourth motor 22 is started to drive the third rotating shaft 23 to rotate, which in turn drives the blade 24 to rotate at high speed to cut the carrot. In addition, the fourth motor 22 can change the tilt angle of the blade 24 by rotating through the second rotating mechanism. In conjunction with the adjustment seat 14 moving through the guide rail mechanism to move the blade 24, and the tilting frame 18 tilting through the second tilting mechanism to adjust the tilt of the blade 24, the cutting angle of the blade 24 on the carrot is changed to meet the needs of cutting irregularly shaped carrots into pieces, and can also be used to cut carrot pieces of different shapes. The cut carrots are continuously output to the outside through the feeding mechanism.

[0047] As a further embodiment of the present invention, the pushing mechanism includes a first cylinder 5 fixed on the movable frame 2. The first cylinder 5 includes a piston rod disposed at the output end. The piston rod passes through the housing of the material cylinder 3 and extends into the interior of the material cylinder 3. The piston rod is fixed to the push plate 6.

[0048] In this embodiment, the first cylinder 5 is electrically connected to an external power source via a wire. Activating the first cylinder 5 can drive the piston rod to extend and retract, thereby moving the push plate 6. The push plate 6 moves within the material cylinder 3 to linearly push the carrots within the material cylinder 3 towards one end of the opening.

[0049] As a further embodiment of the present invention, the first rotating mechanism includes a gear ring 8 sleeved and fixed on the outer periphery of the material cylinder 3, a first motor 10 fixed on the movable frame 2, and a drive gear 9 fixed on the output shaft of the first motor 10, the drive gear 9 meshing with the gear ring 8.

[0050] In this embodiment, the first motor 10 is electrically connected to an external power source via a wire. When the first motor 10 is started, it drives the drive gear 9 to rotate. The drive gear 9 meshes with the gear ring 8 to drive the gear ring 8 to rotate. When the gear ring 8 rotates, it can drive the material cylinder 3 to rotate, thereby driving the carrots clamped by the pneumatic clamp 7 inside the material cylinder 3 to rotate.

[0051] As a further embodiment of the present invention, the first pitch mechanism includes a second cylinder 11 fixed on the frame 1. The second cylinder 11 includes a piston rod with an output end. A rectangular slot frame 12 is fixed at the bottom of the movable frame 2. A limit rod 13 is hinged on the piston rod and is movably engaged inside the rectangular slot frame 12.

[0052] In this embodiment, the second cylinder 11 is electrically connected to an external power source via a wire. Activating the second cylinder 11 drives the piston rod to extend and retract, thereby causing the limiting rod 13 to slide inside the rectangular trough frame 12, which in turn adjusts the pitch angle of the movable frame 2, thereby adjusting the pitch angle of the carrot in the material cylinder 3. The bottom of the rectangular trough frame 12 is provided with a through groove whose inner surface size matches the outer diameter of the piston rod at the output end of the second cylinder 11. The piston rod at the output end of the second cylinder 11 passes through the through groove.

[0053] As a further embodiment of the present invention, the guide rail mechanism includes a guide rail 25 fixed on the frame 1, a slider 26 slidably engaged on the guide rail 25, an adjusting seat 14 fixed on the slider 26, a third cylinder 27 fixed on the guide rail 25, and the slider 26 fixed to the piston rod at the output end of the third cylinder 27.

[0054] In this embodiment, the third cylinder 27 is electrically connected to an external power source via a wire. Activating the third cylinder 27 can drive the piston rod at the output end to extend or retract, thereby causing the slider 26 to slide on the guide rail 25, which in turn causes the adjusting seat 14 to move above the guide rail 25. When the adjusting seat 14 moves, it causes the blade 24 to move and adjust its horizontal position.

[0055] As a further embodiment of the present invention, the second pitch mechanism includes a first rotating shaft 15 rotatably mounted on an adjusting seat 14, a second motor 16 fixed on the adjusting seat 14, the first rotating shaft 15 being mounted on the output end of the second motor 16 and driven to rotate by the second motor 16, a swing arm 17 fixed on the first rotating shaft 15, the swing arm 17 being hinged to the pitch frame 18, and a hinge frame 19 being provided between the pitch frame 18 and the adjusting seat 14, with both ends of the hinge frame 19 being hinged to the pitch frame 18 and the adjusting seat 14 respectively.

[0056] In this embodiment, the second motor 16 is electrically connected to an external power source via a wire. Starting the second motor 16 drives the first rotating shaft 15 to rotate. When the first rotating shaft 15 rotates, it will drive the swing arm 17 to rotate. Since a hinge frame 19 is provided between the pitch frame 18 and the adjustment seat 14, and the two ends of the hinge frame 19 are respectively hinged to the pitch frame 18 and the adjustment seat 14, when the swing arm 17 rotates, it will drive the pitch angle of the pitch frame 18 to be adjusted, thereby driving the pitch angle of the blade 24 to be adjusted.

[0057] As a further embodiment of the present invention, the second rotating mechanism includes a second rotating shaft 20 rotatably disposed at the end of the pitch frame 18, a third motor 21 fixed at the end of the pitch frame 18, the second rotating shaft 20 being mounted on the output end of the third motor 21 and driven to rotate by the third motor 21, and a fourth motor 22 being fixed on the second rotating shaft 20.

[0058] In this embodiment, the third motor 21 is electrically connected to an external power source via a wire. Starting the third motor 21 drives the second rotating shaft 20 to rotate, which in turn drives the fourth motor 22 to rotate. This allows for the adjustment of the rotation of the blade 24 located at the output end of the fourth motor 22, thereby changing the tilt angle of the blade 24.

[0059] As a further embodiment of the present invention, the feeding mechanism includes a feeding hopper 28 fixed on the frame 1. Two first rotating rollers 29 are rotatably mounted on the frame 1 on the inner side of the feeding hopper 28. A second rotating roller 30 is rotatably mounted on one side of each of the two first rotating rollers 29. A fish scale roller 31 is fixed on the first rotating roller 29, and a rotating roller 32 is fixed on the second rotating roller 30. A connecting plate 33 is provided at the ends of the first rotating roller 29 and the second rotating roller 30. The two ends of the connecting plate 33 are rotatably connected to the first rotating roller 29 and the second rotating roller 30, respectively. The two first rotating rollers 29 are driven to rotate synchronously in opposite directions through a first transmission mechanism. The first rotating roller 29 and the second rotating roller 30 are driven synchronously in opposite directions through a first gear mechanism. A fourth cylinder 40 is hinged on the frame 1. The piston rod at the output end of the fourth cylinder 40 is hinged to the connecting plate 33.

[0060] The first transmission mechanism includes a third gear 36 fixed on two first rollers 29 and a fourth gear 37 rotatably mounted on the frame 1. A fifth motor 39 is fixed on the frame 1. A fifth gear 38 is fixed at the output end of the fifth motor 39. The fifth gear 38 meshes with the fourth gear 37 and one of the third gears 36. The fourth gear 37 also meshes with the other third gear 36.

[0061] The first gear mechanism includes a first gear 34 fixed on the second roller 30 and a second gear 35 fixed on the first roller 29, wherein the first gear 34 meshes with the second gear 35.

[0062] In this embodiment, the fifth motor 39 and the fourth cylinder 40 are electrically connected to an external power source via wires. Starting the fifth motor 39 drives the fifth gear 38 to rotate. The fifth gear 38 meshes with the fourth gear 37 and one of the third gears 36. The fourth gear 37 meshes with the other third gear 36. When the fifth gear 38 rotates, it drives one of the third gears 36 and the fourth gear 37 to rotate. The fourth gear 37 also drives the other third gear 36 to rotate, thereby causing the two first rollers 29 to rotate synchronously in opposite directions. The first rollers 29 and the second roller 30 are connected by a first gear mechanism. The first roller 29 rotates in a synchronous reverse transmission, driving the second gear 35 to rotate. The meshing of the first gear 34 and the second gear 35 drives the first gear 34 to rotate, which in turn drives the second roller 30 to rotate. Therefore, when the first roller 29 rotates, it drives the two second rollers 30 to rotate synchronously in opposite directions. Consequently, when the two fish-scale rollers 31 rotate synchronously in opposite directions, they drive the two rotating rollers 32 to rotate synchronously in opposite directions. When carrots are poured into the feeding hopper 28 in batches, the rolling of the fish-scale rollers 31 and the rotating rollers 32 compresses and adjusts the carrots falling into the feeding hopper 28 to a position aligned with the axial direction of the rotating rollers 32. Because the first roller 29 and... A connecting plate 33 is provided at the end of the second rotating roller 30. The two ends of the connecting plate 33 are rotatably connected to the first rotating roller 29 and the second rotating roller 30, respectively. The first rotating roller 29 is rotatably mounted on the frame 1. Therefore, the position of one end of the connecting plate 33 remains unchanged. Activating the fourth cylinder 40 can drive the connecting plate 33 to rotate, thus driving the second rotating roller 30 to rotate around the first rotating roller 29. That is, the second rotating roller 30 can both rotate on its own axis and revolve around the first rotating roller 29. When the bottommost carrot inside the feeding hopper 28 is adjusted to a position consistent with the axial direction of the rotating roller 32, activating the fourth cylinder 40 causes the connecting plate 33 to oscillate and rotate. Roller 32 revolves downward around fish-scale roller 31. At this time, a gap is formed between the two rotating rollers 32. The bottom carrot falls downward under the action of gravity. The groove 4 is located directly below the two rotating rollers 32. Therefore, the carrot falls into the groove 4 and then enters the material cylinder 3. Then, the fourth cylinder 40 is started again to make the two rotating rollers 32 revolve upward around the fish-scale roller 31 respectively, so that the gap between the two rotating rollers 32 is no longer formed. With this feeding method, it is not necessary to manually feed carrots one by one into the cutting equipment. Batch feeding can be achieved, and at the same time, the problem of carrots shifting and getting stuck in the feeding channel will not occur when feeding in batches.

[0063] As a further embodiment of the present invention, the feeding mechanism includes two rollers 42 rotatably mounted on the frame 1, with a conveyor belt 41 cooperating with the outer periphery of the rollers 42 for transmission, and a sixth motor 43 fixed on the frame 1. One roller 42 is mounted on the output end of the sixth motor 43 and is driven to rotate by the sixth motor 43.

[0064] In this embodiment, the sixth motor 43 is electrically connected to an external power source via a wire. Starting the sixth motor 43 drives the drum 42 to rotate. The conveyor belt 41, which is connected to the outer circumference of the drum 42, drives the drum 42 to rotate. As the drum 42 rotates, the carrot pieces cut by the blade 24 fall onto the drum 42 and are output outward through the drum 42. In addition, a guide plate 44 fixed to the frame 1 is provided at one end of the conveyor belt 41 to facilitate the output of materials through the guide plate 44. Baffles 45 fixed to the frame 1 are provided on both sides of the conveyor belt 41 to prevent the carrot pieces that fall onto the conveyor belt 41 from falling outward from both sides of the conveyor belt 41.

[0065] The working principle of this invention is as follows: In use, multiple carrots are added in batches into the feeding hopper 28. The feeding mechanism sequentially conveys the carrots one by one from the slot 4 into the material cylinder 3. The pusher plate 6 moves via a pushing mechanism to push the carrots in the material cylinder 3 to the port of the material cylinder 3. At this time, the pneumatic clamp 7 is activated to clamp the carrots at the port. The rotation angle of the material cylinder 3 can be adjusted by rotating the first rotating mechanism. The tilt angle of the movable frame 2 can be adjusted by tilting the first tilt mechanism, thus changing the orientation and direction of the carrot segments in the material cylinder 3 in three-dimensional space. The fourth motor 22 is activated to drive the third rotating shaft 23. The rotation drives the blade 24 to rotate at high speed to cut the carrot; the fourth motor 22 can change the tilt angle of the blade 24 by rotating through the second rotating mechanism. In conjunction with the adjustment seat 14 moving through the guide rail mechanism to move the blade 24, and the tilting frame 18 adjusting the tilt of the blade 24 through the second tilt mechanism, the cutting angle of the blade 24 on the carrot is changed to meet the needs of cutting irregularly shaped carrots into pieces. At the same time, it can realize the cutting of carrot pieces of different shapes, no longer limited to cubic blocks, and can produce polygons such as pentagons, hexagons, rhombuses, trapezoids, wavy shapes, stars, or irregular polyhedra.

[0066] Here is an example of the workflow for cutting diamond-shaped blocks:

[0067] S1, firstly, the carrot is pushed to the end of the feed cylinder 3 and then clamped by the pneumatic clamp 7;

[0068] S2, rotate the blade 24 to 45°, and tilt the barrel 3 by -10°;

[0069] S3, the first cylinder 5 pushes the carrot to feed 30mm, and the blade 24 rotates at 45° to cut;

[0070] S4, the material cylinder 3 is divided into three parts, each rotating 90° around the Z-axis, while the blade 24 rotates at 45° to cut the carrot, resulting in a rhomboid cross-section.

[0071] S5, the first cylinder 5 pushes the carrot to feed 30mm, the blade 24 returns to zero tilt angle and is in a vertical state to cut the carrot into diamond-shaped blocks;

[0072] S6. Repeat steps S3-S5 until the carrot material is exhausted.

[0073] The above embodiments are exemplary and not restrictive. Therefore, any technical solutions that can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention are included within the scope of the present invention.
