Description

Technical Field

[0001] This invention relates to the field of agricultural automation processing, specifically to a high-efficiency cleaning, root removal, yellowing leaf removal, precise weighing, and packaging machine for leafy vegetables. Background Technology

[0002] In the industrial processing and fresh produce supply chain system of leafy vegetables, leafy vegetables, as agricultural products with high daily consumption frequency and strict freshness requirements, directly impact product quality and supply chain efficiency through efficient and standardized pre-processing and packaging. Traditional leafy vegetable processing relies on manual operation. Workers must manually wash the leaves to remove mud and sand, remove impurities from the roots, then pick out yellow and diseased leaves one by one, and finally weigh and package them manually using a platform scale. This process is not only inefficient, but labor costs also continue to rise with changes in the labor force structure. At the same time, manual washing is prone to leaving mud and sand residue, and the sorting of yellow leaves is affected by subjective judgment, resulting in inconsistent standards. This makes it difficult to meet the requirements of fresh produce retail and pre-prepared vegetable processing scenarios for maintaining the freshness, uniform quality, and accurate measurement of leafy vegetables, seriously restricting the large-scale expansion and standardization upgrade of the leafy vegetable industry.

[0003] Current leafy vegetable processing technologies mostly employ a step-by-step operation mode with single-function equipment. Common equipment, such as stand-alone leafy vegetable washing machines, can only complete basic rinsing and require an additional manual root removal station. Yellow leaf sorting often relies on vibration screening or air sorting, which can only remove obviously wilted yellow leaves and is difficult to handle slightly yellowed or spotted leaves. The weighing and packaging processes are mostly manually coordinated, requiring manual transfer to the packaging machine after weighing, which easily leads to leafy vegetable loss and a decrease in freshness during the intermediate transfer process. In addition, existing equipment lacks an integrated collaborative design, requiring manual handling and coordination between multiple devices, which not only increases the complexity of the operation process but also makes it difficult to improve the overall processing efficiency, failing to meet the current needs of efficient, precise, and low-loss large-scale production in the leafy vegetable processing industry. Therefore, there is an urgent need for an integrated leafy vegetable processing equipment that incorporates automation integration technology to achieve a continuous operation of washing, root removal, yellow leaf removal, accurate weighing, and efficient packaging. This integrated leafy vegetable processing equipment, based on an automated root removal mechanism, a precision sorting component, and a high-precision weighing and packaging linkage module, completes the root removal and yellowing leaf removal operations through a movable blade assembly controlled by preset parameters. After being cleaned by a washing mechanism, the vegetables are weighed by a high-precision weighing module and then directly linked to the packaging unit for bundling. This effectively improves the processing efficiency and quality consistency of leafy vegetables and is suitable for large-scale leafy vegetable processing scenarios. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a highly efficient leafy vegetable cleaning, root removal, yellow leaf removal, precise weighing, and packaging machine. This device enables seamless and precise processing of leafy vegetables throughout the entire process, from automated cleaning, root removal, and yellow leaf removal to precise weighing and efficient packaging. It lays a standardized and low-loss foundation for subsequent fresh produce distribution and pre-prepared vegetable processing, effectively solving the problems of low efficiency in traditional manual processing, cumbersome step-by-step operations with existing single equipment, insufficient accuracy in yellow leaf sorting, large weighing errors, and disconnect between packaging and previous processes.

[0005] The purpose and effectiveness of the leafy vegetable high-efficiency cleaning, root removal, yellow leaf removal, accurate weighing and packaging machine described in this invention are achieved through the following technical solution: A high-efficiency leafy vegetable cleaning, root removal, yellowing leaf removal, precise weighing, and packaging machine includes a root removal and yellowing leaf removal module 1, a leafy vegetable cleaning module 2, a leafy vegetable weighing module 3, and a leafy vegetable packaging module 4.

Above the block conveyor belt 13, the gripper cylinder 15 is fixed below the support frame 14 and connected to the gripper 16. The root-removing knife cylinder 18 and the yellow leaf-removing cylinder 19 are fixed to the side of the support frame 14 and connected to the root-removing knife 17 and the yellow leaf-removing knife 110. The root-removing and yellow leaf-removing module drive wheel 122 is fixed inside the motor housing 12 and connected to the root-removing and yellow leaf-removing module drive wheel 122. The root-removing and yellow leaf-removing module drive wheel 122 is connected to the belt 123. The belt 123 is connected to the conveyor belt roller 124 to drive the root-removing and yellow leaf-removing module conveyor belt 13 to move. The leafy vegetable washing module 2 includes a washing module housing 21, a water spray pipe 22, a washing module conveyor belt 23, a driven wheel 24, and a motor. The belt 25, drive pulley 26, and cleaning module motor 27 are all included. A water spray pipe 22 is embedded in the cleaning module housing 21. The cleaning module motor 27 is fixed to the cleaning module 21. The drive pulley 26 is coaxial with the cleaning module motor 26, and the driven pulley 24 is coaxial with the upper roller of the cleaning module conveyor belt 23. The motor belt 25 is fixed to the drive pulley 26 and the driven pulley 24. The leafy vegetable weighing module 3 includes a support 31, a baffle 32, a partition 33, a cylinder 34, a cylinder bracket 35, a push plate 36, a weighing base plate 37, and a gravity sensor 38. The baffle 32 is fixed to the side of the weighing base plate 37, and the cylinder bracket 35 is fixed above the weighing base plate 37. The cylinder 34 is fixed to the cylinder bracket. Above the frame 35, the partition 33 is fixed inside the cylinder bracket 35. The push plate 36 is connected to the cylinder 34 and placed above the weighing base plate 37. The gravity sensor 38 is fixed below the weighing base plate 37 to weigh the leafy vegetables. The leafy vegetable packaging module 4 includes a packaging module bracket 41, a cable tie wheel 42, a cable tie motor 43, a cable tie torsion device 44, a cable tie knife 45, a packaging hook motor 46, and a packaging hook 47. The cable tie wheel 42 is fixed to the side of the baffle 32. The cable tie motor 43 is fixed to the side of the packaging module bracket 41 to drive the cable tie torsion device 44 to rotate. The packaging hook motor 46 is fixed to the front of the packaging module bracket 41 to drive the packaging hook 47 to rotate.

[0006] The leafy greens are first placed in the root and yellow leaf removal module 1, with the direction of movement aligned with the conveyor belt 13 of the root and yellow leaf removal mechanism. The motor 121 of the root and yellow leaf removal module starts, driving the belt 123 to rotate, which in turn drives the conveyor belt 13 of the root and yellow leaf removal module to rotate. The leafy greens are transported to the support frame 14, where the gripper cylinder 15 pushes the gripper 16 downward to fix the leafy greens. At this time, the root removal knife cylinder 18 and the yellow leaf removal knife cylinder 19 respectively push the root removal knife 17 and the yellow leaf removal knife 110 to move horizontally, removing the yellow leaves and roots of the leafy greens. After the project is completed, the gripper cylinder 15 drives the gripper 16 to move upward, and the leafy greens are then transported by the conveyor belt 13 of the root and yellow leaf removal module to the leafy green washing module 2.

[0007] Subsequently, the cleaning module motor 27 drives the drive wheel 26 to rotate, which in turn drives the motor belt 25 to move, driving the driven wheel 24, causing the cleaning module conveyor belt 23 to rotate. The leafy vegetables are cleaned by water sprayed from the water pipe 22 and gradually transported by the motor belt 25 to the weighing mechanism 3. The leafy vegetables fall onto the weighing mechanism base plate 37, and their weight is measured by the gravity sensor 38. When the weight reaches the desired value, the cylinder 33 pushes the push plate 36 to move, so that it passes through the packaging mechanism 4. The packaging hook motor 46 drives the packaging hook 47 to tie the leafy vegetables with straps. The strap knife 45 cuts off the excess straps, and the strap motor 43 drives the strap torsion device 44 to clamp the straps of the leafy vegetables. Finally, the push plate 36 pushes the vegetables into the frame.

[0008] Compared with the prior art, the present invention has the following advantages and positive effects: 1. This device adopts a targeted adaptive root and yellow leaf removal mechanism. By controlling the cutting position for root and yellow leaf removal through preset operating parameters, it can accurately remove yellow leaves and root impurities from leafy vegetables, achieving standardization and efficiency in root and yellow leaf removal of leafy vegetables. It effectively avoids the problem of inconsistent standards in manual operation, greatly improves the quality consistency of leafy vegetables after processing, and meets the requirements of uniformity of raw materials in fresh food distribution and pre-prepared vegetable processing.

[0009] 2. This device employs a gentle cleaning structure linked with precise weighing and bundling, and is equipped with an adaptive root and yellow leaf removal component. Based on preset parameters for leafy vegetable varieties, it controls the water flow intensity and weighing accuracy, simultaneously completing leafy vegetable cleaning, root removal, and yellow leaf removal operations. This avoids leafy vegetable breakage caused by traditional mechanical hard contact root removal and leaf damage caused by high-pressure water washing. At the same time, the weighing module and automatic bundling mechanism are linked in real time, which can adapt to the loose shape of leafy vegetables to complete neat bundling, avoiding the problem of uneven tightness in manual bundling, effectively ensuring the freshness of leafy vegetables and reducing quality loss during processing.

[0010] 3. Full-process collaborative automation efficiency: The cleaning module, root and yellow leaf removal module, high-precision weighing module and automatic bundling mechanism form a closed-loop linkage. The entire process from root removal, yellow leaf removal, cleaning to accurate measurement and automatic bundling does not require manual intervention. Unlike the traditional discrete mode of manual and single-equipment step-by-step operation, it significantly improves the overall processing efficiency, reduces the manpower input in large-scale processing scenarios, avoids material loss caused by manual connection of each link, and reduces the difficulty of production management and overall cost.
