Description

Technical Field

[0001] This invention relates to the field of scallion peeling technology for food processing, and particularly to a fully automatic integrated device for removing roots, yellow leaves, and peeling scallions. Background Technology

[0002] Before cooking or processing, scallions typically need to have their roots, yellow leaves, and skin removed. Existing scallion peeling devices are all semi-automatic, mainly divided into two categories: conveyor belt air-blowing semi-automatic peeling devices and manual hand-held rotary semi-automatic peeling devices. The core design concept is to peel scallions using only air blowing or manual-assisted rotation combined with air blowing. This can only complete the single step of peeling scallions and requires manual intervention in feeding, sorting, and adjustment, making it impossible to achieve fully automated processing.

[0003] The existing technology has the following significant shortcomings: 1. Low degree of automation: There is no fully automated operation structure design, making it impossible to achieve integrated operation of automatic feeding, automatic root cutting and yellow leaf removal, automatic peeling, and automatic discharge. There are many manual interventions, resulting in high labor intensity. 2. Poor cutting adaptability: The cutting positions for root cutting and yellow leaf removal are fixed structures without adjustment functions, making it impossible to adapt to scallions of different lengths and specifications. The cutting accuracy is poor, and the loss of scallion body is large. 3. Poor peeling effect: The peeling method is singular. It either relies on airflow to passively turn the scallions or on manual hand-held rotation. Neither method can achieve all-round, no-dead-angle air-blowing peeling of scallions. The peeling is incomplete and unclean, resulting in poor processing consistency. 4. Difficulty in separating waste and finished products: During the peeling process, waste peels and soil are mixed with the finished scallions. There is no automatic separation structure, requiring secondary manual sorting, increasing processing steps and reducing production efficiency. 5. Poor process connection: Each processing step is independent of the others. There is no continuous transmission and discharge structure, making it impossible to directly connect to subsequent automatic packaging equipment. The overall processing flow is not smooth, and the adaptability to large-scale processing is poor. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the existing technology by providing a fully automatic scallion root removal, yellow leaf removal, and peeling integrated device. This device can integrate multiple processes such as root cutting, yellow leaf removal, and peeling into one device, realizing fully automated operation of scallion processing, with high work efficiency and good peeling effect.

[0005] The technical solution adopted by the present invention to achieve the above objectives is as follows: a fully automatic integrated device for removing roots, yellow leaves, and peeling scallions, including a bracket and a base plate mounted on the bracket. A roller rotation mechanism is installed on the upper surface of the base plate, and a motor capable of driving the roller rotation mechanism to rotate is installed under the base plate. The motor transmits power to the roller rotation mechanism through a transmission device. A rectangular top plate is provided directly above the base plate. Two opposite corners of the top plate are connected to the base plate through guide posts and guide sleeves, and the other two opposite corners of the top plate are connected to the base plate through lifting cylinders and lifting piston rods, respectively. When the lifting cylinders are working, the entire top plate can move up and down with the guide posts and lifting piston rods. A guide rail and a slider that slides with the guide rail are connected to the bottom surface of the top plate. An air blowing mechanism is connected to the lower side of the slider. The air blowing mechanism is located above the roller rotation mechanism. A push-pull mechanism that can push and pull the air blowing mechanism to reciprocate above the roller rotation mechanism is connected to the lower side of one end of the top plate. Root-removing blades and tail-removing blades extending downwards are connected to the bottom surfaces of the top plate corresponding to the front and rear sides of the roller rotation mechanism, respectively.

[0006] A further technical solution of the present invention is as follows: the roller rotation mechanism includes a synchronous shaft, a synchronous gear, a rotary gear, and rollers. The two ends of the synchronous shaft are mounted on the upper part of the base plate through mounting plates. The motor on the lower part of the base plate transmits power to the synchronous shaft through a transmission device. Three pairs of spaced roller shafts are provided on the upper part of the synchronous shaft. The two ends of the roller shafts are supported by mounting plates. Rotary gears and rollers are respectively connected to the two shafts of each pair of roller shafts. A synchronous gear is installed on the synchronous shaft below the two rotary gears of each pair of roller shafts. Each synchronous gear meshes with the two rotary gears above it at the same time. When the synchronous gear rotates, the rotary gears rotate with the synchronous gears. When the rotary gears rotate, the roller shafts rotate. The rollers on the roller shafts rotate together with the roller shafts.

[0007] A further technical solution of the present invention is as follows: the transmission device includes a driving pulley, a driven pulley, and a belt. The driving pulley is connected to the output shaft of the motor. The driven pulley is located directly above the driving pulley and is fixedly installed on the synchronous rotating shaft. A through hole is provided in the bottom plate between the driving pulley and the driven pulley. The bottom end of the belt is connected to the driving pulley, and the upper end of the belt passes through the through hole and is connected to the driven pulley.

[0008] A further technical solution of the present invention is: a pneumatic tilting and discharging mechanism is provided on the upper surface of the bottom plate on one side of the roller rotation mechanism. The pneumatic tilting and discharging mechanism includes a tilting plate and a tilting cylinder installed on the lower side of the tilting plate to drive the tilting plate to tilt. The tilting plate is hinged to the upper surface of the bottom plate on one side of the roller rotation mechanism through a support. The inner side of the tilting plate extends into the gap between two adjacent pairs of roller shafts. When the tilting cylinder controls the tilting plate to tilt, the tilting plate can tilt the scallions on the roller rotation mechanism onto the conveyor belt on the outer side of the bottom plate.

[0009] A further technical solution of the present invention is as follows: the blowing mechanism includes a gas splitter, a universal base, and a pointed nozzle. The gas splitter is connected to a slider below the top plate through a connecting plate. The bottom end of the gas splitter is connected to a plurality of spaced universal bases. The outlet end of each universal base is connected to a pointed nozzle. The input end of the gas splitter is connected to the outlet end of a high-pressure gas generating device through a high-pressure gas pipe. The push-pull mechanism is connected to the outer wall of one end of the gas splitter.

[0010] A further technical solution of the present invention is as follows: the push-pull mechanism includes an L-shaped mounting plate, a double-rod cylinder, a rocker arm one, and a rocker arm two. The L-shaped mounting plate is connected to the bottom surface of the top plate on the outside of the blowing mechanism. The double-rod cylinder is mounted on the vertical side surface of the L-shaped mounting plate. One push-pull piston rod of the double-rod cylinder extends inward and is connected to the outer wall of the gas distributor. The other push-pull piston rod of the double-rod cylinder extends outward and is hinged to one end of the rocker arm one. The end of the rocker arm one away from the double-rod cylinder is hinged to the rocker arm two through a rocker arm pin. The end of the rocker arm two away from the rocker arm one is hinged to the surface of the L-shaped mounting plate through a hinge shaft.

[0011] A further technical solution of the present invention is: the upper end of the tail-removing blade is connected to an electric push rod capable of adjusting the horizontal position of the tail-removing blade.

[0012] The fully automatic scallion root removal, yellow leaf removal, and peeling integrated device of the present invention has the following beneficial effects: 1. Significantly Enhanced Automation: The material is conveyed to the outside of the rotating roller mechanism via a feeding conveyor belt. A pusher mechanism then pushes the material onto the rotating roller mechanism, where root-removing and tail-removing knives directly cut off the roots and yellow leaves of the scallions. The rotating roller mechanism then rotates the scallions, and a blowing mechanism continuously blows high-pressure gas to peel them. After peeling, a pneumatic flipping and discharging mechanism flips the scallions onto a conveyor belt for direct transport to the packaging equipment for automatic packaging. This achieves a fully integrated operation of automatic feeding, root cutting, yellow leaf removal, automatic rotating peeling, and automatic discharging of scallions, requiring no manual intervention throughout the process. This significantly improves automation, eliminating manual handling, adjustment, sorting, and discharging, greatly reducing labor intensity, saving labor costs, and solving the problem of high reliance on manual labor in existing technologies.

[0013] 2. Significantly enhanced processing adaptability: By connecting an electric push rod to the upper end of the root-removing blade, the electric push rod can flexibly adjust the horizontal position of the root-removing blade, realizing flexible adjustment of the cutting position. It can accurately adapt to the processing needs of scallions of different lengths and specifications, with high cutting precision, effectively reducing scallion waste, improving the yield rate, and solving the problems of fixed cutting position and high loss in existing technologies.

[0014] 3. Significantly improved peeling effect: The rotating roller mechanism makes the scallion rotate continuously during the peeling process, while the push-pull mechanism makes the air blowing mechanism reciprocate above the scallion. This achieves a composite peeling structure of "active rotation of scallion + reciprocating movement of nozzle", which enables 360° air blowing peeling without dead angles. The peeling is cleaner and more uniform, and the processing consistency is significantly improved. The peeling effect is far superior to the existing fixed air and nozzle passive flipping or manual hand-held rotation method.

[0015] 4. Significantly improved processing efficiency: Enables continuous and integrated operation of peeling, rooting, and removing yellow leaves from scallions, eliminating manual interruptions, increasing processing speed, and allowing direct connection to subsequent automatic packaging equipment, reducing intermediate transfer steps. Suitable for factory-scale scallion processing, solving the problem of low processing efficiency in existing technologies.

[0016] 5. Automatic separation of waste and finished products: The outer side of the roller rotary machine is not equipped with baffles. The open processing station enables waste to fall automatically. Combined with the pneumatic tilting discharge mechanism, this special discharge structure enables the automatic conveying of finished products. No manual secondary sorting is required, which improves the hygiene of the processing, simplifies the processing process, and further improves production efficiency.

Detailed Implementation

[0019] like Figures 1 to 5 As shown, the present invention provides a fully automatic scallion root removal, yellow leaf removal, and peeling integrated device, which includes a support 4 and a base plate 6 disposed on the support 4. The present invention also includes a top plate 11, a roller rotation mechanism, an air blowing mechanism, and a push-pull mechanism.

[0020] like Figure 1 , Figure 2 and Figure 5 As shown, a roller rotation mechanism is mounted on the upper surface of the base plate 6, and a motor 17 is mounted under the base plate 6 to drive the roller rotation mechanism. The motor 17 transmits power to the roller rotation mechanism through a transmission device. The roller rotation mechanism is used to support the scallions after the roots and yellow leaves have been removed, and to drive the scallions to rotate continuously around their own axis. Figure 1 and Figure 3 , 4As shown, the roller rotation mechanism includes a synchronous shaft 29, a synchronous gear 30, a rotating gear 7, and a roller 5. The synchronous shaft 29 is mounted on the upper side of the base plate 6 via mounting plates 9 at both ends. Bearings supporting the synchronous shaft 29 are also installed in the mounting plates 9. A motor 17 on the lower side of the base plate 6 transmits power to the synchronous shaft 29 via a transmission device. Three pairs of spaced roller shafts 31 are provided on the upper side of the synchronous shaft 29. The roller shafts 31 are supported at both ends by the mounting plates 9, which also contain bearings supporting the roller shafts 31. A rotating gear 7 and a roller 5 are connected to the two shafts of each pair of roller shafts 31, meaning the rotating gears 7 and rollers 5 are connected in series on each roller shaft 31. A synchronous gear 30 is installed on the synchronous shaft 29 below the two rotating gears 7 of each pair of roller shafts 31. Each synchronous gear 30 meshes simultaneously with the two rotating gears 7 above it, causing the two rotating gears 7 on each pair of roller shafts 31 to rotate in opposite directions. When the motor 17 transmits power to the synchronous shaft 29, the synchronous gear 30 on the synchronous shaft 29 rotates together with the synchronous shaft 29. When the synchronous gear 30 rotates, the rotating gear 7 rotates with the synchronous gear 30. When the rotating gear 7 rotates, the support roller shaft 31 rotates. The roller 5 on the support roller shaft 31 rotates together with the support roller shaft 31. The scallion located on the roller 5 rotates together with the roller 5.

[0021] like Figure 2 As shown, in this embodiment, the transmission device includes a driving pulley 19, a driven pulley 20, and a belt 18. The driving pulley 19 is connected to the output shaft of the motor 17. The driven pulley 20 is located directly above the driving pulley 19 and is fixedly mounted on the synchronous shaft 29. A through hole is provided in the base plate 6 between the driving pulley 19 and the driven pulley 20. The bottom end of the belt 18 is connected to the driving pulley 19, and the upper end of the belt 18 passes through the through hole and is connected to the driven pulley 20. Of course, as a variation of the present invention, the transmission device can also be other transmission devices, such as chain drive or gear drive.

[0022] like Figure 1 , 2 As shown, a pneumatic tilting and discharging mechanism is provided on the upper surface of the base plate 6 on one side of the roller rotation mechanism. This pneumatic tilting and discharging mechanism is a finished product discharge driving component, used to push the peeled scallions to the discharge conveyor belt (not shown in the figure) to achieve automatic discharge. The pneumatic tilting and discharging mechanism includes a tilting plate 3 and a tilting cylinder (not shown in the figure) installed on the lower side of the tilting plate 3 to drive the tilting plate 3 to tilt. The tilting plate 3 is hinged to the upper surface of the base plate 6 on one side of the roller rotation mechanism by a support. The inner side of the tilting plate 3 extends into the gap between two adjacent pairs of roller shafts 31. When the tilting cylinder controls the tilting plate 3 to tilt, the tilting plate 3 can tilt the scallions on the roller rotation mechanism onto the conveyor belt outside the base plate 6.

[0023] like Figure 1 ,2 As shown, a rectangular top plate 11 is positioned directly above the base plate 6. Two opposite corners of the top plate 11 are connected to the base plate 6 via guide posts 2 and guide sleeves 1, respectively. The other two opposite corners of the top plate 11 are connected to the base plate 6 via lifting cylinders 8 and lifting piston rods 10, respectively. When the lifting cylinder 8 is working, the top plate 11 can move up and down with the guide posts 2 and lifting piston rods 10, driving the top plate 11 to rise and fall as a whole, thereby driving the root-removing blade 21 and the tail-removing blade 28 to complete the downward cutting action. The bottom surface of the top plate 11 is connected to a guide rail 23 and a slider 22 that slides with the guide rail 23. An air blowing mechanism is connected to the lower side of the slider 22, and the air blowing mechanism is also located above the roller rotation mechanism. A push-pull mechanism is connected to the lower side of one end of the top plate 11, which can push and pull the air blowing mechanism to reciprocate above the roller rotation mechanism.

[0024] like Figure 1 , 2 As shown, the blowing mechanism is used to blow high-pressure gas onto the surface of scallions to efficiently peel them. The blowing mechanism includes a gas distributor 26, universal bases 25, and pointed nozzles 24. The gas distributor 26 is connected to a slider 22 below the top plate 11 via a connecting plate. Multiple spaced universal bases 25 are connected to the bottom of the gas distributor 26, and each universal base 25 has an outlet connected to a pointed nozzle 24. The input end of the gas distributor 26 is connected to the outlet end of a high-pressure gas generating device (not shown in the figure) via a high-pressure gas pipe. The high-pressure gas generating device can be existing equipment, such as an air compressor or air compression pump. A push-pull mechanism is connected to the outer wall of one end of the gas distributor 26.

[0025] like Figure 1 , 2 As shown, the push-pull mechanism is used to drive the blowing mechanism to reciprocate along the length of the scallion, cooperating with the rotating scallion to achieve full-surface blowing and peeling. The push-pull mechanism includes an L-shaped mounting plate 14, a double-rod cylinder 12, a rocker arm 15, and a rocker arm 26. The L-shaped mounting plate 14 is connected to the bottom surface of the top plate 11 on the outside of the blowing mechanism. The double-rod cylinder 12 is mounted on the vertical side surface of the L-shaped mounting plate 14. One push-pull piston rod 13 of the double-rod cylinder 12 extends inward and connects to the outer wall of the gas distributor 26. The other push-pull piston rod 13 of the double-rod cylinder 12 extends outward and is hinged to one end of the rocker arm 15. The end of the rocker arm 15 away from the double-rod cylinder 12 is hinged to the rocker arm 26 via a rocker arm pin. The end of the rocker arm 26 away from the rocker arm 15 is hinged to the surface of the L-shaped mounting plate 14 via a hinge shaft. The push-pull mechanism drives the air blowing mechanism to reciprocate above the rotating support roller mechanism, forming a composite peeling method of "rotation + reciprocating air blowing" for the scallions, achieving 360° full coverage and efficient peeling of the scallions, with no dead corners and high peeling cleanliness.

[0026] like Figure 1 , 2As shown, a root-removing blade 21 and a tail-removing blade 28 extending downwards are respectively connected to the bottom surface of the top plate 11 on the front and rear sides of the rotating roller mechanism. The upper end of the tail-removing blade 28 is connected to an electric push rod 27 that can adjust the horizontal position of the tail-removing blade 28. The control end of the electric push rod 27 is connected to a control cabinet (not shown in the figure) via a circuit. By driving the tail-removing blade 28 to move back and forth by the electric push rod 27, the cutting position can be flexibly adjusted, allowing for precise adjustment of the yellow leaf removal cutting position and accurate cutting of the yellow leaves of the scallion. Combined with the synchronous cutting of the root-removing blade 21 and the tail-removing blade 28 driven by the lifting cylinder 8, it can adapt to scallions of different lengths and specifications, improving processing adaptability.

[0027] During operation, the overall workflow is as follows: 1. Feeding: The scallions are automatically fed to the processing station by the feeding conveyor belt (not shown in the figure), completing the automatic feeding; 2. Cutting and positioning: The electric push rod 27 on the top plate 11 drives the tail-removing knife 28 to move back and forth according to preset or adjusted parameters, adjusting it to a suitable cutting position matching the length of the scallion; 3. Root cutting and yellow leaf removal: The lifting cylinder 8 is activated, pushing the top plate 11 downward, driving the root-removing knife 21 and the tail-removing knife 28 to press down simultaneously, completing the root cutting and yellow leaf removal of the scallion; 4. Rotation support: After the root cutting and yellow leaf removal are completed, the scallion naturally falls onto the rotating support roller mechanism below, and the roller 5 drives the scallion to rotate continuously around its own axis; 5. All-round peeling: The push-pull mechanism drives the air blowing mechanism to move back and forth along the scallion axis, and the high-pressure airflow blows the rotating scallion 360° in all directions to peel it. The waste peel, soil and other waste generated during peeling automatically fall down, realizing automatic separation from the finished scallion; 6. Reset: After the peeling operation is completed, the lifting cylinder 8 drives the top plate 11 to move upward and return to the initial position, completing the mechanism reset; 7. Discharge: The pneumatic flipping discharge mechanism is activated, flipping outward and pushing the peeled finished scallions to the discharge conveyor belt to achieve automatic discharge; 8. Subsequent connection: The scallions are sent to the automatic packaging mechanism via the discharge conveyor belt to complete the subsequent automatic packaging operation, forming an integrated processing flow.

[0028] The above embodiments are merely preferred embodiments of the present invention. The structure of the present invention is not limited to the forms listed in the above embodiments. Any modifications, equivalent substitutions, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
