Description

Technical Field

[0001] This utility model relates to the field of scallion processing technology, and in particular to a scallion primary processing device. Background Technology

[0002] As an important seasoning vegetable in my country, scallions typically undergo preliminary processing after harvest and before sale, including selection, root and leaf removal, peeling, washing, and bundling. This removes inedible parts, dirt, and old leaves, improving their appearance and hygiene to meet market demands. Some single-function scallion processing equipment has emerged, such as standalone washing machines and root cutters. However, these machines are limited in function and fail to create a continuous, automated workflow. Combining multiple single-function machines results in large footprints, high investment costs, the need for manual handling between processes, and poor overall coordination, failing to fundamentally achieve automated, integrated, and efficient production.

[0003] Current technologies primarily focus on mechanizing individual processes, lacking an integrated device that organically combines key steps such as screening, root and leaf removal, peeling, washing, and bundling for continuous operation. This results in numerous interruptions in the initial processing of scallions, requiring significant manpower for transfer and connection, and limiting automation. There is an urgent need to develop an automated, integrated initial processing device suitable for individual farmers or small-scale production, capable of automating the entire process from screening to bundling of scallions. This would address the problems of high reliance on manual labor, fragmented processes, low efficiency, resource waste, and operational complexity inherent in current technologies.

[0018] Please see Figure 1-5This embodiment provides a scallion primary processing device, including a frame 1, a screening mechanism 2, a transport mechanism 3, a cutting mechanism 4, a pneumatic mechanism 5, a cleaning mechanism 6, and a packaging mechanism 7. The screening mechanism 2 is located at the upper part of one end of the frame 1 and has a feeding port 21. Preferably, a set of identification modules is provided at the feeding port 21 to identify the quality of the scallions. The transport mechanism 3 is located at the lower rear end of the screening mechanism 2. The cutting mechanism 4 is located at the output end of the transport mechanism 3. The pneumatic mechanism 5 is located at the lower end of the cutting mechanism 4. The cleaning mechanism 6 is located at the rear of the pneumatic mechanism 5. The packaging mechanism 7 is located at the end of the cleaning mechanism 6. The outlet end of the screening mechanism 2 corresponds to the starting end of the transport mechanism 3, the outlet end of the cutting mechanism corresponds to the inlet end of the pneumatic mechanism 5, the outlet section of the pneumatic mechanism 5 corresponds to the starting end of the cleaning mechanism 6, and the outlet end of the cleaning mechanism 6 corresponds to the inlet end of the packaging mechanism 7.

[0019] In this embodiment, frame 1 refers to a rigid frame structure used to support and fix the various functional mechanisms. Screening mechanism 2 is located at the upper part of one end of frame 1, used to receive and temporarily store the scallions to be processed. A visual recognition module judges the quality of the scallions to remove substandard products. Transport mechanism 3 is located below and behind screening mechanism 2, and is a continuous conveyor system, such as a conveyor belt, used to receive and transport the screened scallions backward. Cutting mechanism 4 is located at the end of transport mechanism 3, and is an assembly including a motor and its driven rotating blades 42, used to cut and remove the roots and excess leaves of the scallions. Pneumatic mechanism 5 is located below the leaf-cutting and root-removing mechanism, and is a combination including a pair of relatively rotating rollers and an air blowing device pointing towards the gap between the rollers, used to peel the outer skin of the scallions through friction and high-pressure gas. Cleaning mechanism 6 is located behind the pneumatic peeling mechanism, and is an assembly with a spray nozzle group and brush rollers 62, used to spray and brush the peeled scallions to clean their surface. The packaging mechanism 7, located at the end of the cleaning mechanism 6, is an assembly including an infrared recognition sensor 71 and a packaging actuator 72, used to automatically bundle a predetermined number of scallions. The outlet of the screening mechanism 2 corresponds to the starting end of the transport mechanism 3 to complete material transfer; the outlet of the leaf-cutting and root-removing mechanism corresponds to the inlet of the pneumatic peeling mechanism; the outlet of the pneumatic peeling mechanism corresponds to the starting end of the cleaning mechanism 6; and the outlet of the cleaning mechanism 6 corresponds to the inlet of the packaging mechanism 7, thus forming a continuous automated processing line.

[0020] In this embodiment, a complete automated production line is constructed by sequentially connecting and fixing the screening mechanism 2, transport mechanism 3, cutting mechanism 4, pneumatic mechanism 5, cleaning mechanism 6, and packaging mechanism 7 to the frame 1. The screening mechanism 2 realizes automatic judgment of the quality of scallions and accurate rejection of unqualified products, ensuring the consistency of raw material quality. The sequential connection of the transport mechanism 3, cutting mechanism 4, pneumatic mechanism 5, and cleaning mechanism 6 enables the scallions to automatically complete a series of preliminary processing steps such as conveying, root and leaf cutting, outer skin peeling, and surface cleaning, significantly reducing manual intervention. Finally, the packaging mechanism 7 realizes automatic counting and bundling of clean scallions through the coordinated work of infrared recognition sensor 71 and packaging actuator 72. The precise correspondence between the outlets and inlets of each mechanism in the entire device ensures the continuity and stability of material flow, thereby achieving full-process automated processing from raw materials to finished products, effectively improving processing efficiency and standardization.

[0021] Furthermore, in some embodiments, the screening mechanism 2 further includes a feeding plate 22, which is disposed at the front end of the feeding port 21 and is connected to a first drive motor 23.

[0022] In this embodiment, the feeding plate 22 refers to a plate-shaped component that can rotate around an axis. It is located below the front end of the feeding port 21 and is used to receive the scallions to be processed falling from the feeding port 21. The feeding plate 22 is connected to a first drive motor 23, which is a controllable rotary drive device such as a servo motor or a stepper motor. Its output shaft is connected to the rotation shaft of the feeding plate 22 and is used to receive control signals from the identification unit and precisely drive the feeding plate 22 to perform a flipping action. When the identification unit determines that the current scallion is a defective product, the control system commands the first drive motor 23 to start, causing the feeding plate 22 to tilt and flip downwards, so that the defective scallion slides down the surface of the feeding plate 22 and is discharged from the device, completing the automatic rejection. After the rejection action is completed, the first drive motor 23 drives the feeding plate 22 to return to the horizontal receiving state to prepare to receive the next batch of scallions.

[0023] In this embodiment, an automatic sorting mechanism based on the judgment of the identification unit is constructed by setting a rotatable feeding plate 22 and connecting it to the first drive motor 23. When the identification unit determines that the green onion is unqualified, the control system can immediately instruct the first drive motor 23 to drive the feeding plate 22 to perform a precise flipping action, thereby automatically guiding the unqualified product away from the main channel. This design realizes the rapid and automatic rejection of unqualified green onions, replacing traditional manual picking and significantly improving the work efficiency and consistency of the screening process. At the same time, the feeding plate 22 can automatically reset to the receiving state after completing the rejection, ensuring the continuity and stability of the screening process, avoiding interference with subsequent material processing, and enhancing the automation level and reliability of the entire primary processing device.

[0024] Further, in some embodiments, the transport mechanism 3 is a conveyor belt. The start end of the conveyor belt is arranged at the lower end of the screening mechanism 2, and the tail end of the conveyor belt extends to the upper end of the cutting mechanism 4.

[0025] In this embodiment, the transport mechanism 3 refers to the overall functional unit arranged between the screening mechanism 2 and the cutting mechanism 4 for automatically conveying materials between the two. The conveyor belt refers to an annular flexible belt-type conveying device, which, as a specific implementation form of the transport mechanism 3, is used to carry and horizontally convey the screened green Chinese onions. The start end of the conveyor belt refers to its feeding area, which is arranged at a position below the blanking plate 22 in the screening mechanism 2, for reliably receiving the qualified green Chinese onions discharged from the screening mechanism 2. The tail end of the conveyor belt refers to its discharging area, which extends obliquely upward and terminates above the cutting mechanism 4, for guiding and feeding the green Chinese onions conveyed here into the cutting mechanism 4 for subsequent processing. By making the start end and the tail end of the conveyor belt respectively correspond to the outlet of the screening mechanism 2 and the inlet of the cutting mechanism 4, the continuous and automatic flow of green Chinese onions from the screening station to the leaf-cutting and root-removing station is realized, which constitutes the key conveyance in the automated processing flow.

[0026] In this embodiment, an automated material flow path is constructed by precisely making the start end and the tail end of the conveyor belt respectively correspond to the outlet of the screening mechanism 2 and the inlet of the cutting mechanism 4. As a specific form of the transport mechanism 3, the conveyor belt has its start end reliably receiving the screened qualified green Chinese onions, and its tail end automatically guides and feeds the green Chinese onions into the cutting mechanism 4 through oblique extension. This design realizes the continuous and automatic conveyance of green Chinese onions between the screening process and the cutting process without manual intervention, eliminates the manual handling link in traditional operations, not only significantly improves the production efficiency, but also ensures the smoothness and stability of the processing flow, which is the key foundation for constituting an integrated automatic processing line.

[0027] Further, in some embodiments, the cutting mechanism 4 includes a second drive motor 41 and rotary blades 42. At least one set of the rotary blades 42 is provided, and the rotary blades 42 are driven by the second drive motor 41.

[0028] In this embodiment, the cutting mechanism 4 refers to a functional unit located at the end of the transport mechanism 3, used to remove the roots and excess leaves of the scallion. The second drive motor 41 is a rotary drive device that provides power for the cutting action, used to convert electrical energy into mechanical energy to drive the blade assembly to rotate at high speed. The rotating blade 42 is a sharp, high-speed rotary cutting component, of which at least one set is provided; "one set" can be a cutting unit formed by multiple blades arranged along the same axis or along a specific cutting plane. The rotating blade 42 rotates at high speed driven by the motor. When the transport mechanism 3 transports the scallion to its working area, the high-speed rotating blade can quickly and neatly cut and remove the roots and leaves of a predetermined length of the scallion. This design realizes the mechanization and automation of the root and leaf removal process, preparing for the subsequent pneumatic peeling process.

[0029] In this embodiment, an automated cutting unit is constructed by setting up a group of rotating blades 42 driven by a second drive motor 41. The second drive motor 41 provides stable and reliable high-speed rotational power to the rotating blades 42, enabling the rotating blades 42 to perform rapid and neat mechanical cutting of the roots and excess leaves when the scallion is transported to its working area. This design completely replaces the traditional cutting operation that relies on manual hand tools with automated mechanical action, which not only significantly improves the processing efficiency and consistency of the root and leaf removal process and ensures the standardization of cutting quality, but also provides qualified pre-treated materials for the subsequent pneumatic peeling process through continuous mechanical operation, ensuring the smooth connection and automated continuous operation of the overall processing flow.

[0030] Furthermore, in some embodiments, the pneumatic mechanism 5 includes an air-blowing roller 51 and an air-blowing structure 52. Two sets of air-blowing rollers 51 are provided, and the two sets of air-blowing rollers 51 are arranged opposite to each other. The air-blowing structure 52 is disposed at the lower end of the gap between the two sets of air-blowing rollers 51.

[0031] In this embodiment, the pneumatic mechanism refers to a functional unit located below the cutting mechanism 4, used to peel off the outer skin of the scallion through a combination of mechanical friction and pneumatic power. The air-blowing rollers 51 refer to two sets of cylindrical rollers that can rotate in opposite directions, with surfaces possessing a certain degree of friction. The two sets of air-blowing rollers 51 are arranged opposite each other, meaning they are parallel and their rotation axes are on the same horizontal plane, with a gap between them allowing a single scallion to pass through. The air-blowing rollers 51 are used to receive the scallions falling from the cutting mechanism 4, and clamp and transport the scallions downwards through the friction generated by their opposite rotation, while simultaneously loosening their outer skin. The air-blowing structure 52 refers to a device that generates and directionally sprays high-pressure airflow, such as an air nozzle or air knife; it is located at the lower end of the gap between the two sets of air-blowing rollers 51, specifically meaning its airflow direction is aligned with the gap and located below the roller's biting point. The blowing structure 52 is used to precisely blow high-pressure gas into the gap created after the scallion root is cut, based on the loosened outer skin. This causes the outer skin to expand further due to the increased internal air pressure and separate from the scallion body, and is eventually completely peeled off and carried out by the airflow.

[0032] In this embodiment, a highly efficient, primarily non-contact, automated peeling method is achieved by combining the frictional conveying of the roller assembly with the directional jetting of the high-pressure air blowing device. The roller assembly initially loosens the outer skin while conveying the scallions, creating conditions for subsequent peeling; the air blowing device precisely injects high-pressure gas into the natural gaps at the base of the scallion, causing the outer skin to expand, crack, and detach from the inside out. This synergistic effect overcomes the shortcomings of traditional manual peeling or purely mechanical friction peeling, which is inefficient and damages the scallion, achieving rapid, clean, and automated scallion peeling, significantly improving processing efficiency and the appearance of the finished product.

[0033] Furthermore, in some embodiments, a buffer roller 8 is also included, which is disposed between the cutting mechanism 4 and the pneumatic mechanism 5.

[0034] In this embodiment, the buffer roller 8 refers to a cylindrical or near-cylindrical component that can rotate around its own axis and is positioned between the cutting mechanism 4 and the pneumatic peeling mechanism. Its installation position allows it to catch the scallions falling from the cutting mechanism 4 after root and leaf removal. The buffer roller 8 may have a grid or flexible pad inside or around its circumference to cushion the falling scallions and prevent physical damage from direct drop. The buffer roller 8 is connected to the power source of the transport mechanism 3 via a transmission component (such as a synchronous belt) to obtain rotational power. After catching the scallions, its slow rotation smoothly guides and transports them to the next workstation, namely the entrance of the pneumatic peeling mechanism. This design ensures a smooth and orderly transition of processed materials between key process transition points, effectively preventing process interruptions or equipment damage caused by material accumulation, jamming, or disorderly falling.

[0035] In this embodiment, by setting a buffer roller 8 between the cutting mechanism 4 and the pneumatic peeling mechanism, the material connection between processes is effectively optimized. The buffer roller 8, with its internal grid or flexible padding structure, cushions the impact of the falling scallions, preventing physical damage caused by direct drop. Simultaneously, the buffer roller 8 obtains rotational power through connection to the power source of the transport mechanism 3, thereby smoothly and orderly guiding and conveying the received scallions to the inlet of the pneumatic peeling mechanism. This design achieves controlled and smooth material transition between key process transition points, fundamentally avoiding potential material accumulation, jamming, or disorderly falling at these points, ensuring the stability and continuity of subsequent peeling process inputs, and thus ensuring the smooth and reliable operation of the entire automated processing flow.

[0036] Furthermore, in some embodiments, the cleaning mechanism 6 includes a water nozzle 61 and a brush roller 62. The water nozzle 61 is provided in multiple sets and is used to spray out cleaning liquid for cleaning scallions. The brush roller 62 is disposed below the water nozzle 61.

[0037] In this embodiment, the cleaning mechanism 6 refers to a functional unit located after the pneumatic peeling mechanism, used for surface cleaning of the peeled scallions. The water nozzles 61 are multiple devices that spray fluid directionally towards the cleaning area, arranged in multiple sets, distributed along the upper side or above the scallion conveying path. The water nozzles 61 are connected to a water supply system via pipelines, used to continuously or intermittently spray water or mixed cleaning solution onto the scallion surface below them to wash away most of the attached mud and dirt. The brush roller 62 is a rotatable cylindrical component with flexible bristles on its surface; it is located below the water nozzles 61, specifically directly above or to the upper side of the scallion conveying path, maintaining contact with the surface of the scallions during transport. The brush roller 62 is driven to rotate by an independent drive device (such as a motor), used to further remove stubborn stains and residual fine skin flakes through mechanical friction between the bristles and the scallion surface, in addition to spraying, thereby ensuring the thorough cleaning of the scallion surface.

[0038] In this embodiment, the cleaning mechanism 6 refers to a workstation unit located downstream of the pneumatic peeling mechanism, used for surface cleaning of the peeled scallions. The water nozzles 61 refer to multiple liquid spray terminals arranged along the cleaning path; these can be fan-shaped nozzles or direct-flow nozzles with specific angles, connected to an external water source or cleaning fluid supply system via water supply pipes. They are used to continuously spray water or a mist containing detergent onto the surface of the scallions passing downwards, washing away most of the attached dirt, juice, and detached debris. The brush roller 62 is a rotatable cylinder with evenly distributed flexible nylon bristles on its surface. It is installed behind or directly below the spray coverage area of ​​the water nozzles 61, ensuring the scallions immediately come into contact with the rotating bristles after spraying. The brush roller 62 is driven by a motor and uses flexible rolling friction with the moving surface of the scallions to physically remove stubborn dirt and fine skin fragments remaining after rinsing, thereby achieving deep cleaning. The coordinated action of the water nozzle 61 and the brush roller 62 constitutes a two-stage cleaning process of rinsing first and then brushing.

[0039] Furthermore, in some embodiments, the packaging mechanism 7 includes a sensor 71 and a packaging actuator 72. The sensor 71 is an infrared recognition sensor 71, which is used to identify the number of scallions. The packaging actuator is provided in two sets, which are arranged opposite to each other.

[0040] In this embodiment, the packaging mechanism 7 refers to the functional unit located at the end of the cleaning mechanism 6, used to count and bundle the cleaned scallions. The sensor 71 is specifically an infrared recognition sensor 71, a non-contact photoelectric detection device based on the principle of infrared light emission and reception. It is installed above or to the side of the entrance of the packaging mechanism 7 to detect and count the number of scallions passing through its detection area in real time. When the number of scallions passing through reaches a preset value, the sensor 71 sends a trigger signal to the control system. The packaging actuator 72 refers to the mechanical device that specifically performs the bundling action. Two sets are provided, positioned opposite each other on both sides of the scallion conveying path. After receiving the trigger signal from the control system, the two sets of actuators move synchronously towards each other to a predetermined position, cooperating to complete the bundling operations such as tightening, wrapping, or knotting the scallions, and then reset to prepare for the next round of work.

[0041] In this embodiment, the entire process of counting and bundling scallions is automated through the collaborative work of the infrared recognition sensor 71 and the packaging actuator 72. The non-contact detection of the infrared recognition sensor 71 ensures the accuracy and reliability of the quantity statistics, effectively avoiding the errors and inefficiencies of manual counting. The two sets of oppositely positioned packaging actuators 72 synchronously execute opposite movements upon receiving signals, ensuring precise coordination and efficiency in the bundling action, resulting in neat and secure bundling of the finished products. This automated unit is directly connected to the cleaning process, realizing continuous operation from cleaning to packaging without manual intervention. This significantly improves the operational efficiency and standardization of the final processing stage, perfecting the overall automated process of scallion initial processing.

[0042] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: Unlike existing technologies, the above technical solution includes a frame 1, a screening mechanism 2, a transport mechanism 3, a cutting mechanism 4, a pneumatic mechanism 5, a cleaning mechanism 6, and a packaging mechanism 7. The screening mechanism 2 automatically judges the quality of the scallions and accurately removes unqualified products, ensuring the consistency of raw material quality. The sequential connection of the transport mechanism 3, cutting mechanism 4, pneumatic mechanism 5, and cleaning mechanism 6 enables the scallions to automatically complete a series of preliminary processing steps, such as conveying, root and leaf cutting, peeling, and surface cleaning. The packaging mechanism 7, through the coordinated work of the infrared recognition sensor 71 and the packaging actuator 72, realizes the automatic counting and bundling of clean scallions. The precise correspondence between the inlet and outlet of each mechanism in the entire device ensures the continuity and stability of material flow, thereby achieving fully automated processing from raw materials to finished products, effectively improving processing efficiency and standardization. The above description is only a part of the embodiments of this utility model, and does not limit the scope of protection of this utility model.
