Description

Technical Field

[0001] This invention relates to food processing equipment, specifically to a multifunctional fully automatic fruit and vegetable dicing device. Background Technology

[0002] my country's automation technology began to emerge in the mid-20th century. After actively learning from advanced technologies, China's technology matured, leading to large-scale production and ushering in a new chapter of automated manufacturing. In recent years, my country's fruit and vegetable dicing equipment has developed rapidly. However, due to its late start, there is a lack of design and experience in dicing equipment, particularly in the overly complex structural design of dicing machines, the simplistic design of the cutting heads, and the lack of intelligent and integrated process design. For example, Guangdong Meixian Meiyan Blue Algae Co., Ltd. has developed a slicing (dicing) machine. Its working principle is as follows: Material is continuously fed into the equipment through the inlet. Driven by a motor, the rotary cutting cylinder and longitudinal cutting blades rotate at high speed via a belt pulley, simultaneously driving the cross-cutting blade to reciprocate up and down. After entering the rotary cutting cylinder, the material is first sliced ​​into thin slices by the slicing blades. These slices are transported by a conveyor belt and fixed by a clamping device. Then, the cross-cutting blade cuts them into shreds. These shredded materials are further cut by the longitudinal cutting blades, ultimately forming diced finished products. Xinghua Ligong Vegetable Machinery Co., Ltd. has developed a dicing machine whose working process is as follows: Raw materials enter the equipment from the feed hopper and fall into a rotating propeller. Driven by the propeller, the material adheres tightly to the inner wall of the drum under centrifugal force and moves forward with the blades, being cut into thin slices by the slicing blades. The slices are then guided by the slicing guide and fall onto the rotating feed drum. This feed drum works in conjunction with a counter-rotating auxiliary feed shaft to gradually convey the slices to the disc cutter shaft, where they are further cut into strips. The strips are then conveyed to another set of rotating strip cutters, ultimately being cut into the desired shapes, such as cubes, cuboids, or other pre-set dimensions. The entire process achieves continuous automated processing from raw materials to diced pieces. Dong Yinmao, Zhao Hua, and others have developed an aloe vera dicing machine, which cuts materials by lateral and longitudinal cutting with the blade head. However, due to the large contact area with the blades and the sticky nature of aloe vera flesh, it is prone to other contamination.

[0003] In the field of fruit and vegetable dicing equipment, research began earlier abroad, leading to the development of relevant cutting theories and their application in production practice. For example, American scholars Geelk and Rucket M specifically analyzed the relationship between cutting force, cutting speed, and feeding speed. British scholars Choundhury SK et al. analyzed and studied the relationship between cutting parameters and cutting life, and based on their research results, developed structural optimization designs. Alongside the development of related theories, many versatile and reliable mature products have also been developed. For example, the Belgian FAM series products include the FAM fruit dicing machine, the Belgian FAM 3D meat dicing machine FAMFlexifam, and the Belgian FAM 3D vegetable dicing machine Dorphy. Their working principle is roughly the same: the cut material is pushed into the cutting blade by the pressure rollers. First, the disc cutting blade cuts it into strips according to the material's thickness, and then the cross-cutting blade further cuts these strips into cubes. Furthermore, depending on different application scenarios such as cutting fruits and vegetables, differentiated structural designs are implemented, such as adjusting the blade shape and setting up a stepless speed regulation system. Later, domestic manufacturers largely referenced the structural principles of this series of fruit and vegetable dicing machines, which led to parameter mismatches and consequently, issues with the flatness of the cut surfaces when removing larger diced pieces. Japan also invented the ECA multi-functional vegetable cutter, whose structure is similar to the GA-type fruit and vegetable dicing machine developed by Urschel in the United States. It adopts a rotary cutting device and, in addition, features different blades such as slicing blades and combing blades designed for different stages to work together, achieving mechanical simplification and multi-functionality.

[0004] Existing fruit and vegetable dicing machines have the following shortcomings: 1. Standardization of diced shape: Fixed size and shape: difficult to match market segmentation needs. Diced characteristics (size, shape, uniformity) are one of the core competitiveness of fruit and vegetable processing products (such as hot pot ingredients needing large diced pieces, salads needing small diced pieces, and baby food needing fine diced pieces), but traditional equipment has highly fixed diced characteristics due to design limitations.

[0005] Difficulty in size adjustment: It relies on manually changing the blade sets with different spacing (e.g., changing from 3mm to 10mm requires disassembling 3 sets of blade heads), resulting in low adjustment accuracy (error of ±1mm or more). Furthermore, the equipment needs to be recalibrated after changing the blades, which takes more than 30 minutes and cannot meet the rapid switching requirements of small batch and multi-specification orders.

[0006] 2. The automation level is relatively low, lacking automatic cleaning function. Fruits and vegetables need to be cleaned manually or by other cleaning devices, and then transferred to a dicing machine for dicing. This is time-consuming and labor-intensive, and the material transfer process is prone to secondary damage (such as damage to the fruit and vegetable skin and loss of juice), which needs to be improved. Summary of the Invention

[0007] The purpose of this invention is to overcome the above-mentioned problems and provide a multifunctional fully automatic fruit and vegetable dicing device. This dicing device can not only automatically switch blades to obtain diced pieces of different shapes or sizes, but also integrates an automatic cleaning mechanism, which has a high degree of automation, eliminates the need for transfer, and reduces damage to fruits and vegetables.

[0008] The objective of this invention is achieved through the following technical solution: A multifunctional fully automatic fruit and vegetable dicing device includes a fruit and vegetable washing mechanism for automatically washing fruits and vegetables, a fruit and vegetable conveying mechanism for conveying the washed fruits and vegetables, a dicing mechanism for dicing fruits and vegetables, and a collection mechanism for collecting the diced pieces. The front end of the fruit and vegetable conveying mechanism extends below the outlet of the fruit and vegetable washing mechanism, and the rear end of the fruit and vegetable conveying mechanism extends in front of the inlet of the dicing mechanism. The dicing mechanism includes a dicing hopper, a cutting blade assembly, a rotary drive mechanism for driving the cutting blade assembly to rotate, and a transverse drive mechanism for driving the cutting blade assembly to reciprocate laterally. The bottom of the dicing hopper has a fan-shaped dicing outlet. The cutting blade assembly includes a circular blade disc and a cutting blade dropper. The circular blade disc is located below the dicing hopper and is fixedly mounted on the cutting blade dropper. The circular blade disc has multiple blade arrangement areas evenly arranged circumferentially around its center. Each blade arrangement area is fan-shaped, and different blade arrangement areas have different blade structures. The cutting blade dropper has a hollow structure. The rotary drive mechanism drives the cutting blade dropper to rotate, causing the blade structures of the corresponding blade arrangement areas of the circular blade disc to move below the dicing outlet of the dicing hopper. The transverse drive mechanism drives the circular blade disc to perform reciprocating transverse cutting below the dicing outlet of the dicing hopper. The collection mechanism is located directly below the inner cavity of the cutter discharge seat.

[0009] In a preferred embodiment of the present invention, the lateral drive mechanism includes a lateral mounting base, a lateral drive motor, and a lateral transmission assembly. The lateral mounting base is fixedly mounted on the frame, and the lateral drive motor is mounted on the lateral mounting base. The lateral transmission assembly includes a lateral transmission seat, a cam transmission assembly, and a return spring. The lateral transmission seat is mounted on the lateral mounting base via a lateral guide structure, and the rotary drive mechanism is mounted on the lateral transmission seat. The cam transmission assembly includes a lateral transmission cam, a pressure roller, and an integrated transmission rod. The lateral transmission cam is fixedly connected to the lateral drive motor. The circumferential surface of the pressure roller is in contact with the wheel surface of the lateral transmission cam. The pressure roller is rotatably connected to one end of the integrated transmission rod. The integrated transmission rod is laterally slidably connected to the mounting portion of the lateral mounting base, and the other end of the integrated transmission rod is fixedly connected to the lateral transmission base. The return spring is sleeved on the integrated transmission rod, and its two ends abut against the mounting portion of the lateral mounting base and the integrated transmission rod, respectively. With the above structure, during the cutting process, the transverse drive motor drives the transverse transmission cam to rotate. When the contact point between the transverse transmission cam and the pressure roller moves from the proximal point to the distal point of the transverse transmission cam, the pressure roller pushes the integrated transmission rod to move laterally away from the axis of the transverse transmission cam, thereby pushing the circular cutter head to perform transverse cutting. At this time, the return spring is compressed and deformed to store energy. When the contact point between the transverse transmission cam and the pressure roller moves from the distal point to the proximal point of the transverse transmission cam, the return spring recovers its deformation, releases potential energy, and drives the integrated transmission rod to move laterally towards the axis of the transverse transmission cam, that is, to perform a return movement, thereby driving the circular cutter head to perform transverse cutting again (some cutter structures are only suitable for unidirectional cutting). Following the above operation, the circular cutter head is driven to perform transverse cutting in a reciprocating manner until all materials are cut.

[0010] Furthermore, the rotary drive mechanism includes a rotary drive motor and a rotary transmission assembly. The rotary drive motor is mounted on a transverse transmission base, and the rotary transmission assembly includes a worm gear and a worm. The worm gear is integrally fixedly sleeved on the outer wall of the cutter blank holder, which is rotatably connected to the transverse transmission base. The worm is coaxially fixedly connected to the rotary drive motor. With this structure, driven by the rotary drive motor, the worm gear and worm drive the cutter blank holder to rotate, which in turn drives the circular cutter disc to rotate, moving the desired blade structure below the dicing outlet of the dicing bin, thus achieving cutter switching.

[0011] In a preferred embodiment of the present invention, the dicing mechanism further includes an intelligent pressing module, which includes a weight sensor, a pressing cylinder, and a pressing drive mechanism. The weight sensor is disposed below the conveyor belt of the fruit and vegetable conveying mechanism. The pressing cylinder and the pressing drive mechanism are disposed inside the dicing bin. The pressing cylinder is located above the dicing outlet of the dicing bin. The pressing drive mechanism includes a pressing mounting plate, a pressing drive motor, and a pressing transmission assembly. The pressing mounting plate is fixedly disposed on the inner wall of the dicing bin. The pressing drive motor is disposed on the pressing mounting plate. The pressing transmission assembly includes a pressing transmission screw and a pressing transmission screw nut. The pressing transmission screw nut is fixedly connected to the pressing cylinder. The above structure first uses a weight sensor to weigh the fruits and vegetables to be cut, sensing their weight and distribution density in real time (e.g., the weight signal difference between stacked potato chunks and loose strawberry bunches is significant). This weight data is then synchronously transmitted to the back-end control system, which controls different cutting pressures based on the weight: if the material is heavy (e.g., carrot chunks), the screw drives the force plate to apply moderate pressure, preventing the material from sliding due to its own weight and causing cutting deviation; when processing hard and crunchy ingredients (e.g., carrots, potatoes), the pressure drive motor outputs a larger driving force, causing the pressure cylinder to press the material down 3-5 mm, ensuring sufficient cutting force; when processing soft and tender ingredients (e.g., tomatoes, strawberries), the pressure drive motor outputs a smaller driving force, causing the pressure cylinder to press the material down 1-2 mm, reducing crushing damage; for loose leafy vegetables (e.g., cabbage stalks), the pressure drive motor is in a suspended state, reducing pressure loss during cutting. Therefore, this invention can adopt different cutting modes according to different fruits and vegetables, ensuring smooth cutting while improving cutting quality and reducing food waste, adapting to diverse application scenarios.

[0012] Furthermore, the bottom of the inner cavity of the dicing box and the bottom of the pressure cylinder are both conical structures.

[0013] In a preferred embodiment of the present invention, the fruit and vegetable cleaning mechanism includes a cleaning tank and a cleaning execution module, wherein the cleaning execution module includes an aeration cleaning mechanism, a high-pressure spray cleaning mechanism, and a roller brush cleaning mechanism.

[0014] Furthermore, the aeration cleaning mechanism includes a mesh plate, an aeration pipe, an aeration pump, and an aeration supply pipe. The mesh plate and aeration pipe are both inclinedly arranged in the cleaning tank. The aeration pipe is located below the mesh plate. One end of the aeration supply pipe is connected to the aeration pump, and the other end is connected to an aeration pipe. With this structure, before cleaning, water is added to the cleaning tank, with the water level at least 5 cm above the aeration plate. During the bubble cleaning stage, the aeration pump supplies air to the aeration pipe through the aeration supply pipe, creating dense microbubbles in the cleaning tank. The fruits and vegetables are then tumbled and swirled, shedding mud and pesticide residues, achieving initial cleaning.

[0015] Furthermore, the high-pressure spray cleaning mechanism includes high-pressure nozzles, a high-pressure water pump, and a high-pressure water supply pipe. Multiple high-pressure nozzles are provided and positioned above the cleaning tank. The high-pressure water supply pipe is connected to both the high-pressure nozzles and the high-pressure water pump. With this structure, after the bubble cleaning is completed, the high-pressure water pump delivers high-pressure water to the high-pressure nozzles through the high-pressure water supply pipes. The high-pressure nozzles then spray the fruits and vegetables below, achieving further cleaning and a more thorough finish.

[0016] Furthermore, the roller brush cleaning mechanism includes a brush, a roller brush drive motor, and a roller brush transmission assembly. The roller brush transmission assembly includes a roller brush transmission belt and a roller brush transmission pulley. The roller brush transmission belt and the roller brush transmission pulley realize the power transmission between the roller brush drive motor and the brush. The brush rollers are installed in the washing tank. There are two brush rollers, and the ends of the two brush rollers rotate synchronously through a gear set. With the above structure, driven by the brush roller drive motor, the brush rollers rotate at a constant speed, sweeping away stubborn stains on the surface of fruits and vegetables, gently peeling off the fuzz of leafy vegetables or the fibrous roots of root vegetables and other residual impurities, and pulling the fruits and vegetables downwards to achieve the final cleaning of the fruits and vegetables.

[0017] Furthermore, the cleaning tank is equipped with a water outlet, and a sewage discharge assembly is provided at the water outlet. The sewage discharge assembly includes a sewage discharge valve, a sewage discharge fan, and a sewage discharge pipe. After cleaning is completed, the sewage discharge valve is opened and the sewage discharge fan is activated to create a large vortex, which draws sewage and impurities into the sewage discharge pipe for unified treatment.

[0018] Furthermore, the washing tank has a conical bottom with a discharge port, and a discharge switch is installed at the discharge port. After the water is drained, the discharge switch is opened, and the washed fruits and vegetables automatically fall from the discharge port onto the fruit and vegetable conveying mechanism below.

[0019] Furthermore, the upper side wall of the cleaning tank is provided with multiple drainage holes, and a drainage trough is provided on the outside of the side wall of the cleaning tank to collect water and debris from the drainage holes. In this way, floating objects and fine particles flow out through the evenly distributed drainage holes at the top and then out through the external drainage trough.

[0020] In a preferred embodiment of the present invention, the fruit and vegetable conveying mechanism includes a conveyor belt and a fruit and vegetable conveying motor. The specific connection structure of the conveyor belt and the fruit and vegetable conveying motor can be referred to the prior art. A water collection tray is provided below the conveyor belt.

[0021] Compared with the prior art, the present invention has the following advantages: 1. This invention, by setting a circular blade disc with multiple fan-shaped blade arrangement areas, each area configured with a different blade structure, and in conjunction with a rotary drive mechanism, can achieve automatic switching between dicing modes of different shapes and sizes. Compared with the traditional operation method that requires manual blade disc replacement, has low adjustment precision, and is time-consuming, this invention significantly improves the flexibility and efficiency of dicing specification switching, better adapts to the market demand for diverse dicing characteristics, and enhances the market competitiveness of the product.

[0022] 2. This invention integrates a fruit and vegetable washing mechanism, a conveying mechanism, and a dicing mechanism, achieving full automation from washing and conveying to dicing. It eliminates the need for manual material handling, avoiding secondary damage problems such as skin damage and juice loss caused by multiple handling in traditional processes. This saves manpower and improves material integrity and product quality. Attached Figure Description

[0033] Combination Figures 1-4 The roller brush cleaning mechanism includes a bristle roller brush 9, a roller brush drive motor 10, and a roller brush transmission assembly. The roller brush transmission assembly includes a roller brush drive belt and a roller brush drive pulley, which transmit power between the roller brush drive motor 10 and the bristle roller brush 9. Two bristle roller brushes 9 are disposed in the cleaning tank 1, and their ends rotate synchronously via a gear set. Through this structure, driven by the roller brush drive motor 10, the bristle roller brushes 9 rotate at a uniform speed, removing stubborn stains from the surface of fruits and vegetables, gently peeling away residual impurities such as fuzz on leafy vegetables or fibrous roots in root vegetables, and pulling the fruits and vegetables downwards, thus achieving the final cleaning of the fruits and vegetables.

[0034] Combination Figures 1-4 The cleaning tank 1 is equipped with a water outlet, and a sewage discharge assembly is provided at the water outlet. The sewage discharge assembly includes a sewage discharge valve 11, a sewage discharge fan, and a sewage discharge pipe 12.

[0035] Combination Figures 1-4The washing tank 1 has a conical bottom with a discharge port. A discharge switch 13 is installed at the discharge port. The specific structure of the discharge switch 13 can refer to the existing discharge switch structure.

[0038] Combination Figures 1-2 and Figures 5-7 The dicing mechanism includes a dicing feed box 17, a cutting blade assembly, a rotary drive mechanism for driving the cutting blade assembly to rotate, and a transverse drive mechanism for driving the cutting blade assembly to reciprocate laterally. The bottom of the dicing feed box 17 is provided with a fan-shaped dicing outlet 17-1. The cutting blade assembly includes a circular cutter disc 18 and a cutting blade discharge seat 19. The circular cutter disc 18 is located below the dicing feed box 17 and is fixedly mounted on the cutting blade discharge seat 19. The circular cutter disc 18 has multiple feeds arranged around its center. The blade arrangement area is uniformly arranged in a circular direction, and each blade arrangement area is fan-shaped. Different blade arrangement areas are provided with different blade structures 18-1. The cutting blade dropping seat 19 is a hollow structure. The rotary drive mechanism is used to drive the cutting blade dropping seat 19 to rotate, so that the blade structure 18-1 corresponding to the blade arrangement area of ​​the circular cutter disc 18 is transferred to the lower part of the dicing outlet 17-1 of the dicing material box 17. The transverse drive mechanism is used to drive the circular cutter disc 18 to perform reciprocating transverse cutting below the dicing outlet 17-1 of the dicing material box 17. Furthermore, with the center of the circular blade disc 18 as the center, six functional areas are evenly distributed: an 11mm large cube cutting area, a 6mm small cube cutting area, a 4mm coarse shred cutting area, a garlic grinding area, a 2mm thin slicing area, and a 4mm thin slicing area (which can be expanded to include slicing, dicing, etc., as needed). Each area is equipped with a corresponding type of blade: the dicing area uses 17 right-angled precision steel blades (30° blade angle, blade edge treated by vacuum heat treatment to a hardness of HRC58-62), with the blade spacing strictly controlled between 5-20mm. During rotation, the material is "cut" into uniform cubes through the gaps between the blades; the shredding area is equipped with fine, curved blades (blade length 15-30mm, curvature conforming to the requirements of shredding), with the blades arranged radially. During rotation, the material is "shaped" into uniform shreds through continuous cutting.

[0039] Combination Figures 5-6 The lateral drive mechanism includes a lateral mounting base 20, a lateral drive motor 21, and a lateral transmission assembly. The lateral mounting base 20 is fixedly mounted on the frame, and the lateral drive motor 21 is mounted on the lateral mounting base 20. The lateral transmission assembly includes a lateral transmission seat 22, a cam transmission assembly, and a return spring 23. The lateral transmission seat 22 is mounted on the lateral mounting base 20 via a lateral guide structure, and the rotary drive mechanism is mounted on the lateral transmission seat 22. The cam transmission assembly includes a lateral transmission cam 24, a pressure roller 25, and an integrated transmission rod 26. The transverse transmission cam 24 is fixedly connected to the transverse drive motor 21. The circumferential surface of the pressure roller 25 is in contact with the wheel surface of the transverse transmission cam 24. The pressure roller 25 is rotatably connected to one end of the integrated transmission rod 26. The integrated transmission rod 26 is laterally slidably connected to the mounting part of the transverse mounting seat 20. The other end of the integrated transmission rod 26 is fixedly connected to the transverse transmission seat 22. The return spring 23 is sleeved on the integrated transmission rod 26. The two ends of the return spring 23 are respectively pressed against the mounting part of the transverse mounting seat 20 and the integrated transmission rod 26. With the above structure, during the dicing process, the transverse drive motor 21 drives the transverse transmission cam 24 to rotate. When the contact point between the transverse transmission cam 24 and the pressure roller 25 moves from the proximal point to the distal point, the pressure roller 25 pushes the integrated transmission rod 26 to move laterally away from the axis of the transverse transmission cam 24, thereby pushing the circular cutter head 18 to perform transverse cutting. At this time, the return spring 23 is compressed and deformed to store energy. When the contact point between the transverse transmission cam 24 and the pressure roller 25 moves from the distal point to the proximal point, the return spring 23 recovers its deformation, releases potential energy, and drives the integrated transmission rod 26 to move laterally towards the axis of the transverse transmission cam 24, that is, to perform a reset movement, and drives the circular cutter head 18 to perform transverse cutting again (some cutter structures are only suitable for unidirectional cutting). Following the above operation, the circular cutter head 18 is driven to perform transverse cutting repeatedly until all materials are cut.

[0040] Combination Figures 5-6 The rotary drive mechanism includes a rotary drive motor 27 and a rotary transmission assembly. The rotary drive motor 27 is mounted on a transverse transmission base 22. The rotary transmission assembly includes a worm gear 28 and a worm 29. The worm gear 28 is integrally fixedly sleeved on the outer wall of the cutter blank holder 19, which is rotatably connected to the transverse transmission base 22. The worm 29 is coaxially fixedly connected to the rotary drive motor 27. With this structure, driven by the rotary drive motor 27, the worm gear 28 and worm 29 drive the cutter blank holder 19 to rotate, which in turn drives the circular cutter disc 18 to rotate, moving the desired blade structure 18-1 below the dicing outlet 17-1 of the dicing material box 17, thus achieving blade switching.

[0041] Combination Figures 5-7 The dicing mechanism also includes an intelligent pressing module, which includes a weight sensor (not shown in the figure, but can be referenced from existing technology), a pressing cylinder 30, and a pressing drive mechanism. The weight sensor is located below the conveyor belt 15 of the fruit and vegetable conveying mechanism. The pressing cylinder 30 and the pressing drive mechanism are located inside the dicing material box 17. The pressing cylinder 30 is located above the dicing outlet 17-1 of the dicing material box 17. The pressing drive mechanism includes a pressing mounting plate 31, a pressing drive motor 32, and a pressing transmission assembly. The pressing mounting plate 31 is fixedly installed on the inner wall of the dicing material box 17. The pressing drive motor 32 is installed on the pressing mounting plate 31. The pressing transmission assembly includes a pressing transmission screw and a pressing transmission screw nut. The pressing transmission screw nut is fixedly connected to the pressing cylinder 30. Through the above structure, the fruits and vegetables to be cut are first weighed by a weight sensor to sense their weight and distribution density in real time (e.g., the weight signal difference between stacked potato chunks and loose strawberry bunches is significant). The weight data is then synchronously transmitted to the back-end control system, which controls different downward pressures based on the weight: if the detected material is heavy (e.g., carrot chunks), the screw drives the force plate to apply moderate downward pressure to prevent the material from sliding due to its own weight and causing cutting deviation; when processing hard and crunchy ingredients (e.g., carrots, potatoes), the downward pressure drive motor 32 outputs a larger driving force, causing the downward pressure cylinder 30 to press the material down 3-5 mm to ensure sufficient cutting force; when processing soft and tender ingredients (e.g., tomatoes, strawberries), the downward pressure drive motor 32 outputs a smaller driving force, causing the downward pressure cylinder 30 to press the material down 1-2 mm to reduce crushing damage; for fluffy leafy vegetables (e.g., cabbage stalks), the downward pressure drive motor 32 is in a suspended state to reduce downward pressure loss during cutting. Therefore, this invention can adopt different cutting modes according to different fruits and vegetables, ensuring smooth cutting while improving cutting quality and reducing food loss, thus adapting to diverse application scenarios.

[0042] Furthermore, the bottom of the inner cavity of the dicing box 17 and the bottom of the pressure cylinder 30 are both conical structures.

[0043] Combination Figures 1-2 The collection mechanism is located directly below the inner cavity of the cutter discharge seat 19, and the collection mechanism includes a movable collection box 33.

[0044] Example 2 Combination Figures 1-7 The working principle of the multifunctional fully automatic fruit and vegetable dicing device in this embodiment is as follows: First, the fruits and vegetables to be processed are placed in the washing tank 1, and water is added to the tank until it reaches a certain height above the aeration pipe 3. The aeration pump 4 is started, introducing gas into the water through the aeration pipe 3, generating dense microbubbles. This allows the fruits and vegetables to undergo initial cleaning in a turbulent vortex, removing mud, sand, and pesticide residues. Subsequently, the high-pressure water pump 7 sprays high-pressure water downwards through the high-pressure nozzle 6, further rinsing the fruits and vegetables. Next, the roller brush drive motor 10 drives two synchronously rotating brushes 9 to gently remove stubborn stains and residual impurities from the surface of the fruits and vegetables, gradually moving them downwards. During the cleaning process, floating debris and fine particles are discharged through the drain holes at the upper end of the side wall of the washing tank 1 into the drain trough 14. After cleaning, the drain valve 11 is opened and the drain fan is started, sucking the wastewater and impurities into the drain pipe 12 for centralized treatment. After draining, the discharge switch 13 is opened, and the cleaned fruits and vegetables automatically fall from the discharge port at the conical bottom onto the conveyor belt 15 below.

[0045] Driven by the fruit and vegetable conveying motor 16, the conveyor belt 15 smoothly transports the fruits and vegetables to the entrance of the dicing bin 17 of the dicing mechanism. A water collection tray is provided below the conveyor belt 15 to collect residual moisture on the surface of the fruits and vegetables. Before entering the dicing bin 17, a weight sensor located below the conveyor belt 15 weighs the fruits and vegetables and transmits the weight data to the control system in real time.

[0046] When fruits and vegetables enter the dicing bin 17, the control system adjusts the downward pressure of the pressure cylinder 30 through the downward drive motor 32 according to the weight and type of the material: for heavier or hard and brittle ingredients, the downward pressure is increased appropriately to ensure cutting force; for soft and tender ingredients, the downward pressure is reduced to avoid squeezing and damage; for fluffy leafy vegetables, the pressure cylinder 30 can be kept in a suspended state to reduce loss.

[0047] Before the fruits and vegetables enter the dicing bin 17, the rotary drive motor 27 drives the cutter discharge seat 19 and the circular cutter disc 18 to rotate via the worm gear 29 and worm wheel 28, so that the fan-shaped blade arrangement area of ​​the required blade structure 18-1 is aligned with the fan-shaped dicing outlet 17-1 at the bottom of the dicing bin 17. After the fruits and vegetables enter the dicing bin 17, they come out from the dicing outlet 17-1. At this time, the transverse drive motor 21 drives the transverse transmission cam 24 to rotate. Through the cooperation of the transverse transmission cam 24 and the pressure roller 25, and the action of the return spring 23, the transverse transmission seat 22 and the entire cutter assembly mounted on it are driven to reciprocate transversely. The blades on the circular cutter disc 18 cut the fruits and vegetables transversely below the dicing outlet 17-1. The cut diced pieces fall through the inner cavity of the cutter discharge seat 19 and are finally collected by the collection mechanism located directly below, completing the fully automatic operation process from washing and conveying to dicing and collection.

[0048] The above are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
