Description

Technical Field

[0001] This invention relates to the field of food processing equipment manufacturing technology, and in particular to a production line for a fruit and vegetable cleaning machine and its manufacturing process. Background Technology

[0002] Fruits and vegetables are essential ingredients in every household. However, purchased fruits and vegetables often contain pesticide residues and pigments, which are difficult to remove with water and can harm people's physical and mental health.

[0003] To address the challenge of effectively cleaning harmful substances from the surface of fruits and vegetables with just water, a cleaning machine specifically designed for sterilizing and disinfecting fruit and vegetable surfaces has emerged on the market. Also known as a fruit and vegetable disinfection machine, fruit and vegetable purification machine, or fruit and vegetable detoxification machine, this machine utilizes water hydroxyl technology to kill, degrade, and purify bacteria, pesticide residues, and other toxic and harmful substances on the surface of fruits and vegetables, in addition to cleaning away dirt and grime. The manufacturing process typically involves manual assembly and testing to ensure the machine meets production standards.

[0004] Currently, the production and assembly process of fruit and vegetable cleaning machines faces significant challenges in terms of production efficiency, energy utilization, and environmental protection. Specifically, due to the large curvature of the machine's exterior and the numerous internal components, the manufacturing process is relatively complex. This makes it difficult to polish some fine curved surfaces during the grinding and polishing process. Furthermore, the dust generated during grinding and polishing can easily cause secondary contamination of the polished surface, and this dust also poses a hazard to the working environment and the health of operators. Additionally, the assembly and inspection of finished fruit and vegetable cleaning machines are generally done manually, which not only requires high levels of operator skill but is also prone to errors, leading to increased scrap rates and waste. This not only reduces production efficiency but also significantly increases labor costs. Summary of the Invention

[0041] The following is in conjunction with the appendix Figure 1-7 The embodiments of the production line of the fruit and vegetable cleaning machine of the present invention will be described in further detail below.

[0042] Example 1

[0043] A production line for a fruit and vegetable cleaning machine, such as Figure 1 As shown, the system includes a conveyor belt 1, which is equipped with a raw material production device 2, a polishing and grinding device 4, an assembly device 3, and a testing device 5 arranged sequentially from front to back along the processing direction. The raw material production device 2 is used to produce the outer shell and internal parts of the fruit and vegetable cleaning machine. The assembly device 3 is used to assemble the outer shell and internal parts. The testing device 5 is used to perform appearance, function, and safety tests on the assembled fruit and vegetable cleaning machine. The system also includes an automatic control system 6, which is electrically connected to the raw material production device 2, the assembly device 3, the polishing and grinding device 4, and the testing device 5 to automatically control the automatic production, processing, assembly, and testing processes of the fruit and vegetable cleaning machine.

[0044] Specifically, on the production conveyor belt 1, the workstations on both sides of the conveyor belt 1 are equipped with raw material production device 2, assembly device 3, polishing and grinding device 4 and testing device 5. The automated feeding and finished product output of multiple assembly devices 3 are realized without the need for manual loading, unloading, assembly and testing operations, thereby greatly reducing the degree of manual involvement, reducing the number of workers and reducing operating costs.

[0045] In this embodiment, as Figures 2 to 4As shown, the polishing and grinding device 4 includes a worktable 41, a lifting bracket 42 circumferentially arranged around the worktable 41, an external grinding component 43 and a dust treatment component 44 movably connected to the lifting bracket 42. Multiple station fixtures 411 for clamping and fixing the fruit and vegetable cleaning machine are distributed circumferentially on the worktable 41. A clamping component 45 is fixedly connected to each station fixture 411. An internal grinding component 46 is located on one side of the clamping component 45, and is arranged laterally parallel to the clamping component 45. The external grinding component 43 is axially positioned directly above the station fixture 411, and is parallel to the dust treatment component 44 on the lifting bracket 42. The fruit and vegetable cleaning machine is fixed and clamped by the clamping component 45, and its grinding position is automatically adjusted according to the curved shape of the machine. The external grinding component 43 and the internal grinding component 46 polish the inner and outer sides of the machine respectively, while the dust treatment component 44 automatically filters and purifies dust during the polishing process.

[0046] Specifically, when polishing the parts and outer shell of the fruit and vegetable cleaning machine, the parts are fixedly positioned by the clamping component 45, and polished by the external polishing component 43 and the internal polishing component 46. To better adjust the polishing position according to the force applied to the workpiece during the polishing process, the clamping component 45 can be adjusted and fixed according to the curved surface structure of the parts, and works in conjunction with the external polishing component 43 to mimic manual polishing actions, thus enabling thorough polishing of complex curved surfaces. Simultaneously, the external polishing component 43 can be controlled to slide up and down via the lifting bracket 42, and the internal polishing component 46 can polish the interior of the parts, saving polishing time and eliminating the need to change equipment. Furthermore, during the polishing process, the dust treatment component 44 simultaneously treats the debris and dust generated, effectively reducing environmental pollution and health hazards to operators.

[0047] In this embodiment, both the external grinding assembly 43 and the internal grinding assembly 46 are composed of a motor 461 (not shown in the figure), a grinding wheel 462, and a gearbox 463. The bottom of the motor 461 (not shown in the figure) is connected to the grinding assembly for transmission. The grinding wheel 462 is rotatably connected to the output end of the motor 461 (not shown in the figure), and the grinding wheel 462 is detachably connected to the lifting bracket 42. The gearbox 463 is connected to the motor 461 (not shown in the figure) for transmission to control and adjust the rotational speed of the grinding wheel 462 during the grinding process.

[0048] Specifically, the external grinding component 43 is axially positioned, and the internal grinding component 46 is horizontally positioned. After being fixed by the clamping component 45, the external grinding component 43 uses the lifting bracket 42 to grind and polish the outer surface of the workpiece, while the internal grinding component 46 extends the grinding wheel 462 into the interior of the workpiece and grinds its interior. During the grinding process, the grinding position is adjusted by the clamping component 45. The motor 461 is built into the gearbox 463. When grinding the exterior of the parts, the grinding wheel 462 can automatically adjust the grinding speed according to different curved surfaces, thereby accurately grinding every detail. Furthermore, the grinding wheel 462 can be replaced according to the polishing precision requirements, which can improve efficiency during the grinding and polishing process.

[0049] In this embodiment, the dust handling component 44 includes a vacuum cleaner 441 and a filter 442. The suction port of the vacuum cleaner 441 is positioned directly above the grinding wheel 462, and the vacuum cleaner 441 is connected to the filter 442. The filter 442 is installed inside the vacuum cleaner 441 and consists of multiple electrostatic gauze sheets 443 (not shown in the figure) that filter and adsorb dust. The multiple electrostatic gauze sheets 443 (not shown in the figure) are arranged in sequence according to the perforation diameter. Dust is absorbed by the vacuum cleaner 441 and adsorbed in the electrostatic gauze sheets 443 (not shown in the figure) when passing through the filter 442.

[0050] Specifically, debris and dust generated during the grinding and polishing process are easily dispersed into the air. This invention utilizes a dust treatment component 44 set on the same side as the external grinding component 43, and a vacuum cleaner 441 to suck up the debris and dust and discharge them centrally. The suction port of the vacuum cleaner 441 is set directly above the workstation fixture 411, which can effectively clean up the dust uniformly. A filter 442 is set inside the vacuum cleaner 441 for filtration. The filter 442 is made of electrostatic gauze 443. The electrostatic gauze 443 uses its own electrostatic effect to attract dust, which facilitates subsequent centralized treatment and effectively improves the comfort of the working environment.

[0051] In this embodiment, the clamping assembly 45 includes a clamping arm 451, a swing rod 452, and a support rod 453. The support rod 453 is symmetrically arranged on both sides of the workstation fixture 411, and the support rod 453 is connected to the clamping arm 451 and the swing rod 452 respectively. The clamping arm 451 is provided with a clamping port 4511 adapted to the fruit and vegetable cleaning machine. One end of the swing rod 452 is rotatably connected to the support rod 453, and the other end is provided with a positioning pin 4521. The fruit and vegetable cleaning machine is clamped and fixed between the clamping arm 451 and the swing rod 452.

[0052] Specifically, the clamping arm 451 operates similarly to pliers, using the claws on both sides of the clamping arm 451 to fix the workpiece. At the same time, the swing arm 452 on the other side fixes the workpiece between the clamping arm 451 and the swing arm 452 through the positioning pin 4521, which facilitates grinding and polishing of the workpiece. It is worth noting that since there are multiple curved surfaces on the workpiece surface, some of the grooves formed by the curved surfaces are difficult to grind and polish. Therefore, both the clamping arm 451 and the swing arm 452 can be rotated and adjusted according to the processing position. For example, when grinding is performed by the external grinding component 43, the clamping arm 451 and the swing arm 452 can rotate synchronously at multiple angles so that the grooves on the surface of the workpiece can be ground and polished. This makes it suitable for some workpieces with uneven surfaces and high processing difficulty, thereby improving the applicability.

[0053] In this embodiment, as Figure 5 As shown, the raw material production device 2 includes a feeding mechanism 21 and an injection molding mechanism 22. The feeding mechanism 21 is used to transfer plastic granules to the injection molding mechanism 22 for compression molding. The feeding mechanism 21 is located on one side of the injection molding mechanism 22, and the discharge end of the feeding mechanism 21 is connected to the feed end of the injection molding mechanism 22.

[0054] Specifically, during the feeding process of raw material granules, the raw material granules are transferred by the feeding mechanism 21 to the injection molding mechanism 22 for compression molding into a shell. The feeding mechanism 21 includes an infeed cylinder and an outlet cylinder. The infeed cylinder has a hollow structure in the middle, forming an extrusion drying channel. The infeed cylinder is configured with inner and outer layers, forming an annular drying chamber between the inner and outer layers. The extrusion drying channel is connected to the outlet cylinder, which is located at the bottom of the infeed cylinder and inserted into the inlet of the injection molding mechanism 22. The raw material granules enter the extrusion drying channel through the infeed cylinder. The raw material granules are moved upward into the annular drying chamber by the pressure inside the drying channel and then discharged through the discharge cylinder. During the process, the raw material granules undergo preliminary drying in the extrusion drying channel and secondary drying in the annular drying chamber, further enhancing the drying effect of the material. At the same time, the injection molding mechanism 22 uses an injection molding machine, which can heat and inject the dried raw material into the shell of the fruit and vegetable cleaning machine, so that it can be quickly molded into the shell of the fruit and vegetable cleaning machine. The raw material granules are made of biodegradable plastic, which can effectively improve the performance and environmental protection level of the fruit and vegetable cleaning machine.

[0055] In this embodiment, as Figure 6As shown, the assembly device 3 includes a machine base 31, a work station plate 32 set on the machine base 31, a vibratory plate 33 for vibrating and feeding parts, and a pneumatic assembly assembly 34 for assembling multiple parts in sequence. Multiple vibratory plates 33 are provided, and a feeding track 35 is connected between the multiple vibratory plates 33 and the work station plate 32. One end of the feeding track 35 is connected to the discharge end of the vibratory plate 33, and the other end is connected to the pneumatic assembly assembly 34. The pneumatic assembly assembly 34 is arranged around the work station plate 32.

[0056] Specifically, in assembling the components of the fruit and vegetable cleaning machine, different components are first placed into multiple vibratory feeders 33. During assembly, the small parts in the vibratory feeders 33 are assembled individually according to a preset program via the feeding track 35. The vibratory feeders 33 are common vibratory feeding discs in existing technology, and feeding is completed through direct vibration. The workstation plate 32, located at the top center of the machine base 31, can rotate around the axis of the machine base 31. A workpiece positioning component is set on the workstation plate 32 at the position corresponding to the pneumatic assembly component 34. The workpiece positioning component includes a positioning fixture and a limiting block. The limiting block is movably connected to both sides of the positioning fixture. The positioning fixture is used to fix and clamp the outer shell of the fruit and vegetable cleaning machine, and is fixed by the limiting block, thereby facilitating the installation of other components. Through the cooperation of the vibratory feeders and the pneumatic assembly component 34, the material preparation and assembly actions are carried out simultaneously, shortening the feeding and assembly cycle and improving assembly efficiency. The pneumatic assembly component 34 includes a support column, a movable plate slidably connected to the support column, and a three-jaw gripper fixed to the movable plate. The support column provides fixed support on the left and right sides, while the movable plate can adjust the height of the three-jaw gripper up and down to facilitate its gripping of parts for assembly. The three-jaw gripper is directly connected to the movable plate by a multi-link. The transmission control of the multi-link controls the three-jaw gripper to complete the gripping of parts and assembly actions. The entire assembly process is fully automated, reducing manual intervention.

[0057] In this embodiment, the testing device 5 includes a visual inspection mechanism 51 and a performance testing mechanism 52 for testing the fruit and vegetable cleaning machine. The visual inspection mechanism 51 is located on one side of the conveyor belt 1 and uses visual imaging technology to inspect the appearance of the fruit and vegetable cleaning machine. The performance testing mechanism 52 is used to test the cleaning function and sterilization function of the fruit and vegetable cleaning machine.

[0058] Specifically, the visual inspection agency 51 uses a CCD camera combined with a visual inspection system to inspect the appearance of the fruit and vegetable cleaning machine. By comparing it with standard qualified parts, unqualified products are screened out. At the same time, the performance testing agency 52 tests the sterilization and disinfection performance, safety performance, etc. of the fruit and vegetable cleaning machine. The performance testing agency 52 uses the fruit and vegetable cleaning machine to test its sterilization effect in water, the degree of pesticide residue degradation on the surface of fruits and vegetables, the degree of pesticide residue degradation in water, the noise generated during operation, and safety requirements. The testing standard is based on the national standard for fruit and vegetable cleaning machine testing SB / T 11190-2017 controller 62T / CAS 302—2018, thereby quickly screening out products that do not meet the standards during the production process.

[0059] In this embodiment, the automatic control system 6 includes an operating console 61 and a controller 62. The operating console 61 is equipped with multiple operating buttons, and the controller 62 is a programmable logic controller.

[0060] Specifically, when the production line is controlled by the automatic control system 6, multiple operation buttons on the control panel 61 can be used to control the conveyor belt 1, the raw material production device 2, the assembly device 3, the polishing and grinding device 4, and the testing device 5. The controller 62 can be used to program each production process step so that the corresponding production parameters can be adjusted according to production needs.

[0061] Example 2

[0062] A manufacturing process for a fruit and vegetable cleaning machine, such as Figure 7 As shown, the operation steps are as follows:

[0063] S1. Material Selection: Based on the functional requirements and environmental standards of the fruit and vegetable cleaner, a high-molecular compound material is selected to make the outer shell, which is manufactured through one-piece compression molding.

[0064] S2. Design Optimization: The internal structure of the fruit and vegetable cleaner is designed and optimized, including improving the cleaning method, optimizing the component transmission system, and improving the performance of the electrical control system;

[0065] S3. Surface treatment: The surface treatment process of grinding, polishing and coating parts using polishing and grinding device 4.

[0066] S4. Assembly process: The assembly device 3 assembles each component in sequence and assembles the internal components into the outer shell, ensuring that each component can be accurately assembled into a complete fruit and vegetable cleaning machine, and ensuring the efficiency and quality control of the assembly process.

[0067] S5. Test Procedure: Establish a comprehensive test procedure using test device 5, including functional testing, sealing testing, and safety testing, and synchronously transmit the test data to automatic control system 6;

[0068] S6. Quality Control: Establish a strict quality control system using the automatic control system 6 to monitor and inspect each link in the manufacturing process and detect the production status on the production line in real time.

[0069] Specifically, in step S1, the polymer compound material used to make the outer shell is food-grade stainless steel, high-strength plastic, or wear-resistant rubber. Since the outer shell of the fruit and vegetable cleaner needs to have good waterproof performance and meet environmental protection standards, the material used to make the outer shell of the fruit and vegetable cleaner needs to be one of food-grade stainless steel, high-strength plastic, or wear-resistant rubber. These materials ensure safety while also having good waterproof performance, which can greatly extend the service life of the fruit and vegetable cleaner. Meanwhile, the cleaning method in step S2 uses one of the following: electrolytic purification technology, ultrasonic purification technology, ozone purification technology, or water hydroxyl purification technology.

[0070] Different cleaning methods produce varying cleaning effects. Electrolytic sterilization technology, for example, is not ideal in terms of cleaning effectiveness and cannot deeply disinfect fruits and vegetables. When using ozone sterilizers, the capacity is limited by the basin-shaped structure. Ultrasonic cleaning machines can damage the surface of fruits and vegetables when the ultrasonic frequency is too high, posing a potential health hazard. While water-based hydroxyl technology provides good disinfection and eliminates secondary pollution, its high technical barrier limits its widespread application. Therefore, to better adapt to market conditions and demands, the cleaning methods described in this invention can be modified according to actual production needs.

[0071] To further improve the assembly efficiency of parts, CNC machine tools or laser cutting machining technology are used in the grinding, polishing and coating processes of parts in step S3, so as to manufacture parts that meet the design standards, which facilitates subsequent installation, maintenance and replacement of parts.

[0072] In this embodiment, the sealing test in step S5 is specifically performed as follows: by setting up a rubber plate 7, multiple placement slots 71 for holding the fruit and vegetable cleaning machine are evenly opened on the rubber plate 7. During the test, the fruit and vegetable cleaning machine is placed into the placement slot 71 and resin is filled into the placement slot 71. The sealing performance of the fruit and vegetable cleaning machine is judged by observing whether air bubbles are generated.

[0073] Specifically, using resin filling to test the airtightness of fruit and vegetable cleaners makes it easier to observe whether air bubbles are generated, thus quickly determining whether the fruit and vegetable cleaner is leaking and facilitating the identification of substandard products.

[0074] Working principle of the invention:

[0075] In the production of fruit and vegetable cleaning machines, raw materials are first processed through raw material production device 2. Simultaneously, the product's components are polished by grinding and polishing device 4. After polishing, the product is assembled by assembly device 3.
