Description

Technical Field

[0001] This invention relates to the field of agricultural crop processing equipment, and in particular to an automated processing device for peeling, removing the head, tail, and yellow leaves from scallions. Background Technology

[0002] Currently, in the scallion processing industry, small and medium-sized processing workshops and restaurant kitchens mostly use manual labor or simple semi-automatic equipment to process scallions, which presents the following core problems: 1. Poor adaptability: Traditional pressing devices cannot adaptively adjust according to the thickness of the scallions, which can easily lead to the scallions shifting, rolling, or being damaged during the conveying process, resulting in a high rate of defective products. 2. Poor processing results: Manual peeling easily leaves behind dirt and impurities; the airflow pressure of semi-automatic peeling equipment is not adjustable, which can easily damage the onion; the cutting blade speed is fixed and cannot be adapted to onions in different stages, resulting in uneven cuts; cutting yellow leaves relies on manual judgment, which is inaccurate and inefficient. 3. Poor process coordination: Each processing step is arranged independently, without continuous transmission, requiring manual transfer of scallions, which increases labor intensity and time loss; 4. Hygiene standards not met: Some equipment components are made of materials that do not meet food processing requirements, which can easily introduce contamination and fail to meet food processing hygiene standards.

[0003] Existing equipment lacks an integrated design that combines adaptive pressing, efficient peeling, precise cutting, and visual removal of yellow leaves, making it difficult to meet the needs of small- to medium-sized batches of stable scallion processing. Summary of the Invention

However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the invention, and these aspects of the invention can be implemented even without these specific details.

[0019] like Figure 1As shown, an automated processing device for peeling, removing heads, tails, and removing yellow leaves from scallions includes a preliminary processing conveyor belt 1, an adaptive pressing belt mechanism 2, an air-blowing peeling mechanism 3, a cutting mechanism 4, and a yellow leaf cutting mechanism 5. The cutting mechanism 4 is respectively arranged on both sides of the middle of the preliminary processing conveyor belt 1. A pressing bracket 6 is arranged in the middle of the preliminary processing conveyor belt 1, and the cutting mechanism 4 is arranged below the pressing bracket 6. The preliminary processing conveyor belt, as the core transmission component, is horizontally arranged along the length of the machine and runs through the entire device to realize continuous conveying of scallions. The bandwidth is matched with each functional mechanism to ensure stable transmission of scallions. The adaptive pressing belt mechanism 2 is arranged above the pressing bracket 6, and the air-blowing peeling mechanism 3 is arranged at the front end of the adaptive pressing belt mechanism 2. Cutting brackets 7 are arranged on both sides of the discharge end of the preliminary processing conveyor belt 1. The yellow leaf cutting mechanism 5 is arranged on the cutting brackets 7 and is equipped with a visual recognition yellow leaf removal device 8. A waste collection box 9 is arranged at the bottom of the preliminary processing conveyor belt 1. The scallions to be processed are evenly placed at the front end of the preliminary processing conveyor belt 1. The conveyor belt continuously transports the scallions to the adaptive pressing belt mechanism 2 for adaptive positioning, the air-blowing peeling mechanism 3 for peeling, the cutting mechanism 4 for cutting off the top and bottom, and the yellow leaf cutting mechanism 5 for cutting off the yellow leaves. The waste is collected by the waste collection box 9 at the bottom of the preliminary processing conveyor belt 1. The waste collection box is installed in the frame below the cutting mechanism and the yellow leaf removal mechanism. It collects cutting waste and yellow leaves through the discharge port, which is convenient for regular cleaning and keeps the processing environment clean.

[0020] like Figure 2 As shown, the adaptive pressure belt mechanism 2 includes a belt bracket 21 and a pressure belt 22. One end of the belt bracket 21 is respectively provided with a pressure drive wheel 25 and a belt motor 24. The output end of the belt motor 24 is connected to the pressure drive wheel 25. The other end of the belt bracket 21 is provided with a pressure driven wheel 26. The top of the belt bracket 21 is provided with a spring roller mechanism 23. The bottom and bottom of the belt bracket 21 are respectively provided with a plurality of spring roller mechanisms 23. The pressure belt 22 is wound around the pressure drive wheel 25, the spring roller mechanism 23 and the pressure driven wheel 26. When the scallions pass under the pressing belt 22 along the preliminary processing conveyor belt 1, the top of the scallions contacts the pressing belt 22 and generates an upward pushing force. This force is transmitted through the pressing belt 22 to the pressing driven wheel 26, which pushes the compression spring of the spring roller mechanism 23 to contract, causing the rubber-coated roller of the spring roller mechanism 23 to move upward, so that the pressing belt 22 automatically conforms to the diameter contour of the scallion, forming a flexible pressing force. At the same time, the belt motor 24 drives the pressing drive wheel 25 to rotate, and the friction between the pressing drive wheel 25 and the pressing belt 22 drives the belt to run synchronously, which works with the conveyor belt below to achieve smooth transmission of the scallions and avoid the scallions from shifting, rolling or being damaged during the transmission process.

[0021] The adaptive belt clamping mechanism is installed above the preliminary processing conveyor belt. The spring roller mechanism uses stainless steel compression springs with an elastic stroke of 8-25mm, suitable for scallions with a diameter of 0.5-3cm. The drive belt is made of food-grade wear-resistant rubber with a surface anti-slip embossed texture height of 1-2mm. The drive and driven pulleys are made of aluminum alloy with a silicone coating on the outer ring, and the coaxiality error is ≤0.1mm. The drive motor is a speed-regulating motor with a speed of 300-1200r / min, linked to the conveyor belt speed for synchronous transmission. The belt spacing is adaptively adjusted by the elastic extension and contraction of the springs to flexibly clamp the scallions and avoid misalignment and damage.

[0022] like Figure 3 As shown, the cutting mechanism 4 includes a cutting motor base 41, a cutting motor 42, and a cutting blade 43. The cutting motor base 41 is connected to the preliminary processing conveyor belt 1, and the cutting motor 42 is connected to the cutting motor base 41. The output end of the cutting motor 42 passes through the cutting motor base 41, and the cutting blade 43 is connected to the output end of the cutting motor 42. When the preliminary processing conveyor belt 1 conveys the scallions to the cutting mechanism 4, there are gaps between the belt sides of the preliminary processing conveyor belt 1 and the frame. The cutting blade 43 cuts the head and tail of the scallion. The cutting motor 42 drives the cutting blade 43 to rotate at high speed. Through the shearing force of the serrated blade, the withered leaf end of the scallion head and the root end of the scallion tail are quickly removed, completing the head and tail cutting operation. The cutting motor 42 is fixed to the frame of the preliminary processing conveyor belt 1 through the cutting motor base 41. The output shaft of the cutting motor 42 and the central shaft of the cutting blade 43 are fastened together by a coupling, resulting in high transmission efficiency and strong operational stability.

[0023] The cutting mechanism is located in the middle of the machine and consists of a motor base, food-grade stainless steel serrated blades, and a drive motor. The blade diameter is 8-12cm, and the rotation speed is adjustable from 1500-3000r / min. The drive motor is rigidly connected to the blade, resulting in high transmission efficiency. It is linked with the conveyor belt speed to achieve precise quantitative cutting of the head and tail of the scallion, resulting in a smooth cut without any loss.

[0024] like Figure 4As shown, the spring roller mechanism 23 includes a vertical bearing 231, a shock absorber mounting base 232, a shock absorber 233, a rubber-coated roller 234, and a rotating shaft 235. The vertical bearing 231 and the shock absorber mounting base 232 are respectively connected to the belt bracket 21. The rotating shaft 235 is rotatably mounted on the vertical bearing 231. Fixed plates 236 are symmetrically arranged at both ends of the rotating shaft 235. Both ends of the rubber-coated roller 234 are hinged to the fixed plates 236. One end of the shock absorber 233 is hinged to the shock absorber mounting base 232 through a connecting shaft. The other end of the shock absorber 233 is hinged between the two fixed plates 236 through an isolation column 237. The shock absorber 233 is inclined. In use, when the scallions are conveyed to the area below the pressing belt 22 by the preliminary processing conveyor belt 1, the top of the scallions pushes the pressing belt 22 upward. The pressing belt 22 drives the rubber-coated roller 234 to move upward synchronously through friction. When the rubber-coated roller 234 moves upward, it squeezes the upper shock absorber 233, causing the compression spring of the shock absorber 233 to contract and generate reverse elastic pressure. This pressure is transmitted to the surface of the scallions through the rubber-coated roller 234 and the pressing belt 22, forming a flexible pressing force that adapts to the thickness of the scallions. At the same time, the pressing belt 22 runs under the drive of the pressing drive wheel 25, and through the pressing belt 22 and the rubber-coated roller 234... The friction generated by the anti-slip stripes on the surface of 34 drives the rubber-coated roller 234 to rotate synchronously. After the scallion has completely passed through the pressing area, the upward thrust on the pressing belt 22 disappears, and the compression spring of the shock absorber 233 extends under the action of elastic restoring force, pushing the rubber-coated roller 234 to move downward, and driving the pressing belt 22 back to the initial pressing position. The rubber-coated roller 234 returns to the initial height with the spring, maintaining a tight fit with the pressing belt 22, preparing for the pressing and transmission of the next batch of scallions. If the entire pressing mechanism stops working, the rubber-coated roller 234 remains stationary and ready to go under the support of the shock absorber 233.

[0025] In an embodiment of the present invention, the air-blowing peeling mechanism 3 includes a plurality of air nozzles 31, which are respectively connected to the belt support 21 via connectors. Each air nozzle 31 is connected to an air pipe connector via an air pipe, and the air pipe connector is connected to an air pump 32 via an air pipe. The air pump 32 is connected to one side of the preliminary processing conveyor belt 1. The air-blowing peeling mechanism is located at the machine's feed end, above the starting section of the conveyor belt, and is fixed to the belt pressing mechanism. It contains an array of high-pressure air nozzles, which are arranged at an angle towards the surface of the conveyor belt. The air-blowing peeling mechanism employs a high-pressure airflow jet design, with adjustable airflow pressure, effectively removing dirt, impurities, and loose outer skin from the surface of the scallions.

[0026] The air-blowing peeling mechanism is located above the preliminary processing conveyor belt at the feeding end and is fixed to the belt pressing mechanism. It consists of an air pump, air pipe connector, air pipe, air nozzle array, mounting bracket, and airflow regulating valve. The air pump is an oil-free silent air compressor with a working pressure of 0.3-0.8MPa and noise level below 60dB. The air nozzle array contains 8-12 stainless steel air nozzles with an orifice diameter of 0.8-1.2mm and a spray angle of 30°-60°, tilted towards the scallions. The air pipe is a food-grade PU hose, and the air pipe connector is a quick-connect structure. The mounting bracket height is adjustable from 10-25cm. It removes dirt, impurities, and loose outer skin from the surface of the scallions by spraying high-pressure air.

[0027] like Figure 5 As shown, the yellow leaf cutting mechanism 5 includes a cutting stepper motor 51, a cutting timing belt 52, a first optical axis 53, an optical axis fixing seat 54, a scissor lifting mechanism 55, and a rectangular blade 56. The optical axis fixing seat 54 is connected to the upper end of the cutting bracket 7. The cutting stepper motor 51 is connected to one side of the right optical axis fixing seat 54. The output end of the cutting stepper motor 51 is connected to a timing belt shaft 57. The left optical axis fixing seat 54 contains a timing belt shaft 57. The cutting timing belt 52 is wound around the cutting bracket 7. On the two synchronous belt shafts 57, the left synchronous belt shaft 57 is provided with a synchronous belt tensioning mechanism 58. The two first optical shafts 53 are respectively connected between the two optical shaft fixing seats 54. The scissor lifting mechanism 55 is slidably connected to the two first optical shafts 53 through the first connecting member 60, and the first connecting member 60 is connected to the cutting synchronous belt 52 through the second connecting member 61. The rectangular blade 56 is provided at the bottom of the scissor lifting mechanism 55. The visual recognition yellow leaf removal device 8 is provided on the scissor lifting mechanism 55. When the scallions are conveyed to the yellow leaf cutting mechanism 5 via the conveyor belt, the yellow leaf removal device 8 identifies the distribution position of the yellow leaves and transmits the signal to the external control system. The external control system controls the cutting stepper motor 51 to start according to the signal command, and drives the scissor lifting mechanism 55 to move along the first optical axis 53 to the corresponding position of the yellow leaf through the cutting synchronous belt 52. Then, the connecting rod of the scissor lifting mechanism 55 deflects synchronously, driving the rectangular blade 56 to move downward precisely, and the blade is in contact with the yellow leaf of the scallion to cut. After the cutting is completed, the scissor lifting mechanism 55 quickly rises, and the cutting stepper motor drives the cutting synchronous belt 52 to reset the mechanism or move it to the next yellow leaf position, and continue to complete the yellow leaf removal operation.

[0028] The yellow leaf cutting mechanism is located at the discharge end and consists of a tensioning mechanism, synchronous belt, optical axis fixing seat, optical axis, stepper motor, scissor lifting mechanism, and stainless steel yellow leaf removal blades. The stepper motor has a step angle accuracy of 1.8°, a step speed of 50-300r / min with stepless adjustment, and a positioning accuracy of 0.05mm. The scissor lifting mechanism uses carbon fiber connecting rods and has a lifting stroke of 10-50mm. The blades are made of food-grade stainless steel with a thin, curved design and a thickness of 0.3-0.5mm. By visually identifying the position of the yellow leaves, the stepper motor drives the scissor lifting mechanism to move the blades for precise cutting, avoiding damage to the white part of the scallion.

[0029] like Figure 6 As shown, the scissor lifting mechanism 55 includes an upper connecting rod fixing seat 551 and a lower connecting rod fixing seat 552. The bottom of the upper connecting rod fixing seat 551 is hinged to an upper left connecting rod 553 and an upper right connecting rod 554. One end of the upper left connecting rod 553 is hinged to a left middle connecting rod 555, and one end of the left middle connecting rod 555 is hinged to a lower right connecting rod 558. One end of the lower right connecting rod 558 is provided with a right gear 559, which is hinged to the lower connecting rod fixing seat 552. The upper right connecting rod 554... One end of the device is hinged to a right middle connecting rod 556, on which a scissor servo 557 is mounted. The output end of the scissor servo 557 is connected to a left middle connecting rod 555. One end of the right middle connecting rod 556 is connected to a lower left connecting rod 560, on which a left gear 561 is mounted. The left gear 561 is hinged to a lower connecting rod fixing seat 552 and meshes with a right gear 559. The rectangular blade 56 is connected to the bottom of the lower connecting rod fixing seat 552.

[0030] When the scissor servo 557 is powered on and drives the left middle link 555 and the right middle link 556 to rotate synchronously inward around the connecting center axis of the scissor servo 557, this rotation is transmitted through the hinge points to the upper right link 554, the upper left link 553, the lower right link 558, and the lower left link 560 respectively. The upper right link 554, the upper left link 553, the lower right link 558, and the lower left link 560 together drive the lower end link fixing seat 552 (tail end) to move downward, thereby driving the bottom blade to move downward synchronously, realizing the cutting operation of the scallion. When the scissor servo 557 rotates in the opposite direction, its head and tail drive the left middle link 555 and the right middle link 556 to rotate synchronously outward around the connecting center axis of the servo, and each link moves in the opposite direction according to the above transmission chain. This drives the lower end link fixing seat 552 and the blade to return upward, preparing for the next cutting operation.

[0031] Through a differentiated transmission design using multi-link linkages, the tail-end blades can be conveniently positioned to work together for vertical cutting, resulting in stronger positioning stability and effectively preventing offset or wobbling during scallion cutting. The upper translational guide structure, combined with the stable vertical displacement at the lower end, ensures precise blade cutting trajectory, making it suitable for cutting slender vegetables such as scallions. The lightweight design of the carbon fiber linkages, combined with the precise control of the servo motor, enables fast and stable cutting action, making it suitable for small vegetable processing equipment, household automatic vegetable cutting devices, and other scenarios.

[0032] This invention has the following characteristics: 1. Integrated continuous processing: Integrating conveyor belt, adaptive pressing, air blowing peeling, head and tail cutting, visual recognition to remove yellow leaves, and waste collection functions, it realizes continuous processing of scallions from feeding to finished product, reducing manual intervention and labor intensity; 2. Enhanced adaptability: The compression mechanism with elastic support structure is adapted to scallions with a diameter of 0.5-3cm, avoiding conveying deviation and skin damage; 3. Optimized processing precision: Adjustable high-pressure airflow is used for peeling, accurately removing impurities without damaging the scallion; high-speed stainless steel blades achieve quantitative cutting at both ends, resulting in neat cuts; visual recognition combined with a scissor-type lifting mechanism accurately removes yellow leaves; 4. Meets hygiene standards: The core components are made of food-grade materials, meeting the hygiene requirements for food processing, and are suitable for small and medium-sized vegetable processing workshops, restaurant kitchens, and other similar settings.

[0033] Working principle The scallions to be processed are evenly placed on the front end of the preliminary processing conveyor belt 11. When the scallions pass under the pressure belt 22 of the adaptive pressure belt mechanism 2, the top of the scallion contacts the pressure belt 22 and generates an upward pushing force. This force is transmitted through the pressure belt 22 to the pressure driven wheel 26, which pushes the compression spring of the spring roller mechanism 23 to contract, causing the rubber-coated roller of the spring roller mechanism 23 to move upward, so that the pressure belt 22 automatically conforms to the diameter contour of the scallion, forming a flexible pressure force; the air nozzle 31 of the air-blowing peeling mechanism 3 peels the scallions; when the preliminary processing conveyor belt 1 transports the scallions to the cutting mechanism 4, the cutting motor 42 drives the cutting blade 43 to cut the head and tail of the scallions; when the scallions pass through When the conveyor belt transports the material to the area below the yellow leaf cutting mechanism 5, the front-mounted vision recognition yellow leaf removal device 8 identifies the distribution position of the yellow leaves and transmits the signal to the external control system. The external control system controls the cutting stepper motor 51 to start according to the signal command, and drives the scissor lifting mechanism 55 to move along the first optical axis 53 to the corresponding position of the yellow leaf through the cutting synchronous belt 52. Then, the connecting rod of the scissor lifting mechanism 55 deflects synchronously, driving the rectangular blade 56 to move downward precisely. The blade of the rectangular blade 56 cuts the yellow leaf of the scallion by contacting it. After the cutting is completed, the scissor lifting mechanism 55 quickly rises, and the cutting stepper motor drives the cutting synchronous belt 52 to reset the mechanism or move it to the next yellow leaf position, continuously completing the yellow leaf removal operation.
