Description

Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to a mango peeling device and its automated operating method. Background Technology

[0002] Mango peeling is a key step in the deep processing of fruit. Existing equipment is mainly divided into two types: friction and kneading type and cutting type. Among them, the cutting type is widely used because of its stable peeling effect and controllable fruit pulp loss. It achieves peeling by fixing the mango at the top and bottom and driving it to rotate, and then using the side-fixed blades to perform vertical reciprocating cutting.

[0003] The current cutting equipment relies on manual labor for feeding, requiring mangoes to be inserted vertically into the workstation one by one. This is not only cumbersome to operate and has low feeding efficiency, but also the fixed clamping parts at both ends of the mango cannot be cut, creating a cutting dead angle. After peeling the mango, the remaining peel at the sharp ends needs to be trimmed manually, which affects the continuity and automation of the production line. Summary of the Invention

[0004] In view of the problems of low efficiency of manual feeding and semi-automatic peeling in the above-mentioned or existing technologies, and the need for secondary processing of the end peel, the present invention is proposed.

[0013] As a preferred embodiment of the mango peeling device of the present invention, the peeling mechanism further includes an installation platform disposed inside the installation frame, a first cylinder disposed outside the installation platform, a connecting groove plate disposed at the end of the first cylinder, a servo motor disposed outside the connecting groove plate, a power shaft extending into the connecting groove plate disposed at the end of the servo motor, a lower shaft extending downward into the connecting groove plate and having a transmission bevel gear disposed at the bottom, and a power bevel gear perpendicularly meshing with the transmission is disposed outside the power shaft.

[0014] As a preferred embodiment of the mango peeling device of the present invention, a second cylinder is also provided outside the mounting frame, part of the upper shaft is provided at the end of the second cylinder, the upper shaft is connected by a connecting rod, a positioning column is provided outside the connecting rod, and a linkage frame is provided at the end of the positioning column.

[0015] As a preferred embodiment of the mango peeling device of the present invention, a cutting device is provided inside the mounting frame, the cutting device includes a cutting blade, a conveyor belt is also provided inside the mounting frame, and a guide plate corresponding to the cutting blade is provided outside the conveyor belt.

[0016] As a preferred embodiment of the automated operation method of the mango peeling device of the present invention, S1: Loading and straightening: The mangoes are piled in the collection trough. The conveyor belt starts and conveys the mangoes one by one to the guide plate through the conveyor plate. The mangoes fall into the loading trough through the guide plate. At this time, the loading trough is in a horizontal state. The drive motor starts and drives the rotating roller to rotate. Taking advantage of the long and narrow shape of the mango and its central center of gravity, the mangoes fall between the two rollers under the drive of the rotating roller and remain parallel to the direction of the roller axis, thus completing the posture straightening. S2: Flipping and end peeling. The servo cylinder in the flipping component is activated, pushing the feeding trough upward through the connecting seat and transmission seat. The feeding trough flips around the rotating frame to a vertical position, and the bottom of the mango falls into the placement ring and abuts against the knife holder at the end of the lower shaft. The conical blades at the ends of the upper and lower shafts respectively fit with the two ends of the mango. The rotating roller continues to rotate and drives the mango to rotate. The conical blades at the upper and lower ends cut off the peel of the mango end in a ring. At the same time, the auxiliary roller, under the action of the second spring, always presses against the side of the mango to ensure that the mango rotates stably during the peeling process. S3: Clamping and Transfer After the end peeling is completed, the first cylinder and the second cylinder are started, driving the upper shaft and the lower shaft to move relative to each other. The shaft needles insert into both ends of the mango to achieve fixed clamping. Then the upper shaft and the lower shaft rise synchronously, driving the mango to leave the feeding trough from the transfer trough and move to the cutting blade of the cutting device. S4: Peeling the main body, the servo motor starts, and the lower shaft and mango rotate through the meshing of the power bevel gear and the transmission bevel gear. The cutting blade moves back and forth along the mango axis under the drive of the lifting frame to peel the mango surface. During the cutting process, the cutting device and the servo motor run alternately until the mango skin is completely removed. The peel produced by cutting falls into the conveyor belt through the guide plate and is discharged. S5: Unloading. After the main body is peeled, the upper and lower shafts retract synchronously. After the mango loses its clamping limit, it falls along the guide plate onto the conveyor belt and is transported to the next process by the conveyor belt, completing the automated peeling operation.

[0017] The beneficial effects of the mango peeling device of the present invention: This invention achieves fully automated operation of mangoes from random stacking to orientation, end peeling, body peeling, and unloading through the coordinated cooperation of the feeding mechanism, processing mechanism, and peeling mechanism. It replaces the traditional manual insertion and feeding, improving feeding efficiency. The horizontally arranged rotating rollers in the processing mechanism utilize the long and narrow shape and centrally located center of gravity of the mangoes to automatically adjust mangoes of any posture to be between the two rollers and parallel to the roller axis by rotation. This achieves orientation alignment without visual recognition or complex mechanical guidance, simplifies the equipment structure, and reduces manufacturing costs.

[0018] The rotating roller of this invention performs a composite function in the processing mechanism. In the horizontal state, it is used to straighten the mango's posture. After vertical flipping, it continues to serve as a rotation drive source to drive the mango to rotate. Together with the conical blades arranged in a ring inside the upper and lower blade holders, it completes the peeling of the ends. This solves the problem of the fruit peel residue at the clamping parts at both ends of the existing equipment requiring secondary manual trimming. The entire process requires no manual intervention, which improves production efficiency and reduces equipment and processing costs. Attached Figure Description

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0025] Example 1, referring to Figures 1 to 6 This is the first embodiment of the present invention, which provides a mango peeling device, including a mounting frame 1; Furthermore, there is a feeding mechanism 2 installed at the front end of the mounting frame 1, a processing mechanism 3 installed between the feeding mechanism 2 and the mounting frame 1, and a peeling mechanism 4 installed inside the mounting frame 1. Furthermore, the feeding mechanism 2 includes a plurality of conveyor belts 22 installed at an incline at the front end of the mounting frame 1; Specifically, the processing mechanism 3 includes a processing table 31 disposed at the end of the conveyor belt 22, a feeding trough 32 disposed on the processing table 31, a rotating roller 323 disposed inside the feeding trough 32, and a flipping member 33 disposed outside the feeding trough 32. Furthermore, the processing mechanism 3 includes a processing table 31 installed at the end of the conveyor belt 22. A flip-up feeding trough 32 is movably connected to the processing table 31. A rotating roller 323 is movably connected inside the feeding trough 32. The outer wall of the rotating roller 323 is made of rubber. A flipping component 33 is installed at the bottom of the feeding trough 32. Specifically, the peeling mechanism 4 includes an upper shaft 42 and a lower shaft 41 disposed inside the mounting frame 1. Both the upper shaft 42 and the lower shaft 41 are provided with sharpening blades 43 at their ends, and auxiliary parts 44 are provided on the outside of the sharpening blades 43. Furthermore, the peeling mechanism 4 includes an upper shaft 42 and a lower shaft 41 that are movably disposed inside the mounting frame 1 and can move up and down. A sharpening blade 43 is installed at one end of the upper shaft 42 and the lower shaft 41 that are close to each other. An auxiliary component 44 is installed at the rear end of the sharpening blade 43. Specifically, the auxiliary component 44 includes a fixing frame 441 disposed inside the mounting frame 1, and an auxiliary roller 444 disposed outside the fixing frame 441; Furthermore, the auxiliary component 44 includes a fixed frame 441 installed inside the mounting frame 1, and a rotatable auxiliary roller 444 is rotatably connected to the front end of the fixed frame 441. In summary, the conveyor belt 22 transports mangoes to the feeding trough 32. When the feeding trough 32 is placed horizontally, the rotating roller 323 rotates, causing the mangoes to rotate and fall between the rotating rollers 323. Utilizing the long and narrow shape of the mangoes and their centrally located center of gravity, the rotation of the rotating rollers 323 can adjust the posture of the mangoes. When the feeding trough 32 is flipped vertically by the flipping component 33 and the mangoes are pressed against the auxiliary rollers 444, the upper shaft 42 and the lower shaft 41 clamp the ends of the mangoes. At this time, the rotation of the rotating rollers 323 causes the mangoes to rotate, allowing the two ends of the mangoes to be peeled by the sharpening knife 43. Thus, the active rotation of the rotating drum plays different roles in the two processes.

[0026] Specifically, the feeding mechanism 2 also includes a material collection trough 21 disposed at the bottom of the conveyor belt 22. The inner wall of the material collection trough 21 is an inclined surface oriented towards the conveying direction. A conveying plate 23 is disposed on the outside of the conveyor belt 22.

[0027] Furthermore, the feeding mechanism 2 also includes a material collection trough 21 installed at the bottom of the conveyor belt 22. The inner wall of the material collection trough 21 is an inclined surface facing the conveying direction, so that the mangoes inside accumulate and fall towards the bottom of the conveyor belt 22. Multiple conveying plates 23 are installed at equal intervals on the outer wall of the conveyor belt 22. A guide plate 24 corresponding to the feeding trough 32 and inclined is installed at the end of the conveyor belt 22.

[0028] Specifically, the processing table 31 has an external mounting groove 311, the feeding trough 32 is movably disposed in the mounting groove 311, one side of the feeding trough 32 is provided with a placement ring 322 that cooperates with the lower shaft 41, the other side of the feeding trough 32 is provided with a transfer trough 325, the processing table 31 is provided with a baffle plate 313, the feeding trough 32 is provided with a baffle plate 321, the rotating rollers 323 are arranged in pairs and multiple sets are provided, the rotating rollers 323 correspond to the conveyor belt 22, the rotating rollers 323 are rotatably disposed in the feeding trough 32 through shaft holes, and a drive motor 324 is provided on the outside of the rotating rollers 323.

[0029] Furthermore, the top of the processing table 31 is provided with an installation groove 311, and the feeding trough 32 is movably connected in the installation groove 311. The rear end of the feeding trough 32 is provided with a placement ring 322 that corresponds to and cooperates with the lower shaft 41. The front end of the feeding trough 32 is provided with a transfer trough 325. The top of the processing table 31 is provided with a baffle plate 313 corresponding to the transfer trough 325. Multiple baffle plates 321 that surround the rotating cylinder are installed in the feeding trough 32. The rotating rollers 323 are arranged in pairs and multiple sets are parallel to each other. The rotating rollers 323 correspond to the conveyor belt 22. The rotating rollers 323 are rotatably arranged in the feeding trough 32 through shaft holes. The front end of the rotating rollers 323 is provided with a drive motor 324 for driving the rotating cylinder to rotate.

[0030] Specifically, the flipping component 33 includes a fixed base 332 disposed at the bottom of the processing table 31. A servo cylinder 331 is disposed outside the fixed base 332. The servo cylinder 331 is rotatably disposed in the fixed base 332 through a shaft hole. A connecting seat 333 is disposed at the end of the servo cylinder 331. A transmission seat 334 is disposed outside the feeding trough 32. The connecting seat 333 and the transmission seat are rotatably connected through a shaft hole. The processing table 31 has an opening 312 for the connecting seat 333 and the transmission seat 334 to move. A rotating frame 335 is also disposed outside the processing table 31. A shaft is rotatably connected to the rotating frame 335 outside the feeding trough 32.

[0031] Furthermore, the flipping component 33 includes a fixed base 332 mounted on the frame at the bottom of the processing table 31. A servo cylinder 331 is rotatably connected to the outside of the fixed base 332. The servo cylinder 331 is rotatably connected to the fixed base 332 through a shaft hole. A connecting seat 333 is installed at the end of the servo cylinder 331. A transmission seat 334 is installed at the bottom of the feeding trough 32. The connecting seat 333 and the transmission seat are rotatably connected through a shaft hole. The processing table 31 has an opening 312 for the connecting seat 333 and the transmission seat 334 to move. A rotating frame 335 is symmetrically mounted at the rear end of the processing table 31. A shaft rotatably connected between the rotating frames 335 is symmetrically mounted at the rear end of the feeding trough 32, so that the entire feeding trough 32 can be flipped by the rotating frame 335.

[0032] During the peeling process, mangoes are piled in the collection trough 21, and then the conveyor belt 22 is started. The conveyor belt 22 transports the mangoes in the collection trough 21 one by one upward through the conveyor plate 23. When the mangoes are transported to the end by the conveyor belt 22, they enter the feeding trough 32 through the guide plate 24. At this time, the drive motor 324 outside the rotating drum in the feeding trough 32 is started, which drives the rotating drum to rotate. The rotating drum moves the mangoes on the rotating drum. Since the mangoes are long and the center of gravity is in the middle, as the rotating drum rotates, no matter what the mangoes are in at the beginning, they will move to the space between the two rotating drums and be parallel to the rotating drums, thus completing the adjustment of the mangoes' posture. At this time, the flipping part 33 can be started. During the flipping process, the servo cylinder 331 is activated, causing the cylinder rod to extend. At this time, the cylinder rod pushes the feeding trough 32 upward from the bottom through the connecting seat 333 and the transmission seat 334. The feeding trough 32 then moves backward through the rotating frame 335 until it is vertical. During the flipping process of the feeding trough 32, the mango falls into the placement ring 322 at one end as the feeding trough 32 tilts. When the feeding trough 32 is completely vertical, the front end of the mango is a rotating cylinder, and the rear end of the mango is an auxiliary cylinder. At this time, the rotation of the rotating cylinder can drive the mango to rotate, and the mango is peeled at both ends. After the upper shaft rod 42 and the lower shaft rod 41 clamp the mango through the cylinder, the mango is carried upward from the transfer trough 325 out of the feeding trough 32 and then moved to the cutting device 48 for peeling.

[0033] Example 2, refer to Figures 7 to 10 This is the second embodiment of the present invention, which differs from the previous embodiment in that it includes an auxiliary component 44; Specifically, the auxiliary component 44 further includes a fixed cylinder 442 disposed inside the fixed frame 441, a clamping seat 445 disposed outside the auxiliary roller 444, the auxiliary roller 444 being rotatably connected to the clamping seat 445 through a shaft hole, a movable cylinder 446 inserted into the fixed cylinder 442 disposed outside the clamping seat 445, and a second spring 443 cooperating with the movable cylinder 446 disposed inside the fixed cylinder 442.

[0034] Furthermore, the auxiliary component 44 also includes a plurality of fixed cylinders 442 installed inside the fixed frame 441. A clamping seat 445 is rotatably provided on the outside of the auxiliary roller 444. The auxiliary roller 444 is rotatably connected to the clamping seat 445 through a shaft hole. A movable cylinder 446 is installed at the rear end of the clamping seat 445, which is inserted into the fixed cylinder 442 and moves and extends along the fixed cylinder 442. A second spring 443 is installed inside the fixed cylinder 442, which contacts and cooperates with the movable cylinder 446.

[0035] Specifically, the sharpening knife 43 includes a knife holder 431 movably disposed at the ends of the upper shaft 42 and the lower shaft 41. The knife holder 431 is provided with conical blades 432 arranged in a ring inside. The conical blades 432 are inclined. The placement ring 322 and the transfer groove 325 are both corresponding to the conical blades 432.

[0036] Furthermore, the sharpening knife 43 includes an annular knife holder 431 movably connected to the ends of the upper shaft 42 and the lower shaft 41. The inner wall of the knife holder 431 is equipped with a plurality of annularly arranged conical blades 432. All the conical blades 432 are inclined towards the side away from the mango. The conical blades 432 are sharpened on both sides. When the feeding groove 32 is flipped, the placement ring 322 and the transfer groove 325 are perpendicular to the conical blades 432.

[0037] Specifically, the tool holder 431 is also provided with a sliding plate 433 inside, and a telescopic pin 434 is provided on the outside of the sliding plate 433. The upper shaft 42 and the lower shaft 41 are both provided with sliding grooves 412 on the outside. The sliding grooves 412 are provided with telescopic holes 413. The sliding plate 433 and the telescopic pin 434 slide up and down along the sliding grooves 412 and the telescopic holes 413 respectively. A first spring 414 that cooperates with the telescopic pin 434 is provided in the telescopic hole 413. The ends of the upper shaft 42 and the lower shaft 41 are both provided with shaft pins 411.

[0038] Furthermore, a sliding plate 433 is symmetrically installed inside the blade holder 431. A telescopic pin 434 is installed at the bottom of the sliding plate 433. The outer walls of the upper shaft 42 and the lower shaft 41 are symmetrically provided with sliding grooves 412. The bottom surface of the sliding groove 412 is provided with a telescopic hole 413. The sliding plate 433 and the telescopic pin 434 slide up and down along the sliding groove 412 and the telescopic hole 413 respectively. A first spring 414 that cooperates with the telescopic pin 434 is installed in the telescopic hole 413. The first spring 414 can press the blade holder 431 tightly onto the mango. The ends of the upper shaft 42 and the lower shaft 41 are each provided with a ring of pins 411 that are intersected with the conical blade 432.

[0039] It should be noted that after the feeding trough 32 flips and causes the mango to stand upright, when peeling both ends is performed, the bottom of the upright mango is located inside the placement ring 322. The placement ring 322 of the flipped feeding trough 32 is parallel to the top of the knife holder 431 at the end of the lower shaft 41 that has not extended. At this time, the bottom of the mango is placed directly on the knife holder 431. The first spring 414 pushes the knife holder 431 upward so that the conical blade 432 fits tightly with the end of the mango. At the same time, it prevents the shaft needle 411 from piercing the end of the mango and causing the mango to be unable to rotate. At this time, the cylinder at the top position is in free piston mode. The upper shaft 42 falls naturally so that the knife holder 431 contacts the top of the mango. The spring cannot be fully compressed to peel the top of the mango. After peeling both ends is completed, the first cylinder 451 and the second cylinder 47 start at the same time and move closer to each other to clamp the mango. The spring is fully compressed so that the shaft needle 411 passes through the knife holder 431 to fix the mango.

[0040] With the mango upright, the blade holders 431 on the upper shaft 42 and lower shaft 41 are tightly fitted to both ends of the mango. The rotating cylinder rotates, causing the mango to rotate. The mango starts to rotate while the blade holders 431 remain stationary. Therefore, the peel of the rotating mango at both ends is cut off by the conical blades 432 inside the blade holders 431. Since the second spring 443 on the outside of the auxiliary cylinder always keeps the auxiliary cylinder facing the mango through the movable cylinder 446 and the clamping seat 445, the mango can be stably fitted to the rotating cylinder and can rotate stably under the action of the rotating cylinder. After the cutting at both ends is completed, when the upper shaft 42 and lower shaft 41 move the mango upward out of the feeding trough 32, the mango squeezes the second spring 443, causing the auxiliary cylinder to move outward to make enough space for the mango to pass through. The whole process does not require manual operation and realizes automated operation.

[0041] Example 2, refer to Figures 11 to 12 This is the third embodiment of the present invention, which differs from the above embodiments in that it includes a cutting and unloading component; Specifically, the peeling mechanism 4 further includes a mounting platform 45 disposed inside the mounting frame 1. A first cylinder 451 is disposed outside the mounting platform 45. A connecting groove plate 461 is disposed at the end of the first cylinder 451. A servo motor 46 is disposed outside the connecting groove plate 461. A power shaft 462 extending into the connecting groove plate 461 is disposed at the end of the servo motor 46. The lower shaft 41 extends downward into the connecting groove plate 461 and is provided with a transmission bevel gear 464 at its bottom. A power bevel gear 463 that meshes perpendicularly with the transmission is disposed outside the power shaft 462.

[0042] Furthermore, the peeling mechanism 4 also includes a mounting platform 45 installed at the bottom of the mounting frame 1. A first cylinder 451 is symmetrically mounted on the upper end of the mounting platform 45. A hollow connecting slot plate 461 is installed at the end of the first cylinder 451.

A lower shaft 41 extends downward into the connecting slot plate 461 and is fitted with a transmission bevel gear 464 at its bottom. The lower shaft 41 and the connecting slot plate 461 are rotatably connected by a bearing. A power bevel gear 463 that meshes perpendicularly with the transmission is installed on the outer wall of the power shaft 462, so that when the servo motor 46 starts, it can drive all the lower shafts 41 to rotate.

[0043] Specifically, a second cylinder 47 is also provided outside the mounting frame 1, and part of the upper shaft 42 is provided at the end of the second cylinder 47. The upper shaft 42 is connected by a connecting rod 421. A positioning post 423 is provided outside the connecting rod 421, and a linkage frame 422 is provided at the end of the positioning post 423.

[0044] Furthermore, the top of the mounting frame 1 is symmetrically equipped with second cylinders 47, and the upper shafts 42 on the left and right sides are installed at the ends of the second cylinders 47. Several upper shafts 42 in the middle are connected to the upper shafts 42 on both sides through connecting rods 421. The top of the connecting rods 421 is equipped with positioning columns 423 that pass through the mounting frame 1 and are movably connected to the mounting frame 1. A linkage frame 422 is installed on the upper end of the positioning column 423.

[0045] Specifically, the mounting frame 1 is equipped with a cutting device 48, which includes a cutting blade 481. The mounting frame 1 is also equipped with a conveyor belt 5, and the outside of the conveyor belt 5 is equipped with a guide plate 51 corresponding to the cutting blade 481.

[0046] Furthermore, a cutting device 48 is provided inside the mounting frame 1, the cutting device 48 includes a cutting blade 481, and a conveyor belt 5 located at a high position is also installed inside the mounting frame 1, and a guide plate 51 corresponding to the cutting blade 481 is installed on the outside of the conveyor belt 5.

[0047] In this embodiment and the other embodiments described above, the electronic devices are all controlled uniformly by a PLC controller.

[0048] The cutting device 48 is a conventional prior art, including a lifting frame and a drive mechanism. The cutting blade 481 is fixed on the lifting frame and is driven by a cylinder or push rod motor to reciprocate linearly along the axis of the mango. After the mango is clamped and fixed by the shafts at the upper and lower ends, it is driven to rotate by the motor. During the rotation of the mango, the cutting blade 481 moves up and down along the axis to peel off the peel layer by layer. Unlike the prior art, the present invention only sets up one cutting blade 481, which is located on the side close to the conveyor belt 5. The bottom is a guide plate 51, which can ensure that the cut peel is collected.

[0049] After the upper shaft 42 and lower shaft 41 carry the mango upward out of the feeding trough 32, the mango is located at the front end of the cutting device 48. Since the mango is clamped by the upper shaft 42 and lower shaft 41, it can rotate with the rotation of the lower shaft 41. At this time, the servo motor 46 is started, which drives the power shaft 462 to rotate. The power shaft 462 drives the power bevel gear 463 on the outer wall to rotate. The power bevel gear 463 drives the driven bevel gear to rotate. The driven bevel gear drives the lower shaft 41 to rotate. The lower shaft 41 drives the mango to rotate. By controlling the alternating operation of the servo motor 46 and the cutting device 48, the mango can be fully cut and peeled. The cut peel falls onto the conveyor belt 5 along the guide plate 51. After the cutting is completed, the upper shaft 42 and lower shaft 41 retract simultaneously, so that the cut mango loses its limit and falls downward through the guide plate 51 onto the conveyor belt 5. At this time, the mango that has been fully peeled at both ends and on the outside can be discharged through the conveyor belt 5 for collection.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.

10. An automated operating method for a mango peeling device, based on the mango peeling device according to any one of claims 1-9, characterized in that, Includes the following steps: S1: Loading and straightening: The mangoes are piled in the collection trough (21). The conveyor belt (22) is started and the mangoes are conveyed one by one to the guide plate (24) through the conveyor plate (23). The mangoes fall into the loading trough (32) through the guide plate (24). At this time, the loading trough (32) is in a horizontal state. The drive motor (324) is started and drives the rotating roller (323) to rotate. Taking advantage of the long strip shape of the mango and the characteristic of the center of gravity being in the middle, the mangoes fall between the two rollers under the drive of the rotating roller (323) and remain parallel to the direction of the roller axis, thus completing the posture straightening. S2: Flipping and end peeling. The servo cylinder (331) in the flipping component (33) is activated, and the feeding trough (32) is pushed upward through the connecting seat (333) and the transmission seat (334). The feeding trough (32) flips around the rotating frame (335) to a vertical state. The bottom of the mango falls into the placement ring (322) and abuts against the knife holder (431) at the end of the lower shaft (41). The conical blades (432) at the ends of the upper shaft (42) and the lower shaft (41) respectively fit against the two ends of the mango. The rotating roller (323) continues to rotate and drives the mango to rotate. The conical blades (432) at the upper and lower ends cut off the peel of the mango end in a ring. At the same time, the auxiliary roller (444) presses against the side of the mango under the action of the second spring (443) to ensure that the mango rotates stably during the peeling process. S3: Clamping and transfer. After the end peeling is completed, the first cylinder (451) and the second cylinder (47) are started, driving the upper shaft (42) and the lower shaft (41) to move relative to each other. The shaft needle (411) is inserted into both ends of the mango to achieve fixed clamping. Then the upper shaft (42) and the lower shaft (41) rise synchronously, driving the mango to leave the feeding trough (32) from the transfer trough (325) and move to the cutting blade (481) of the cutting device (48). S4: Peeling the main body, the servo motor (46) starts, and drives the lower shaft (41) and mango to rotate through the meshing of the power bevel gear (463) and the transmission bevel gear (464). The cutting blade (481) moves back and forth along the mango axis under the drive of the lifting frame to peel the mango surface. During the cutting process, the cutting device (48) and the servo motor (46) run alternately until the mango peel is completely removed. The peel produced by cutting falls into the conveyor belt (5) through the guide plate (51) and is discharged. S5: After the main body is peeled, the upper shaft (42) and the lower shaft (41) retract synchronously. After the mango loses its clamping limit, it falls along the guide plate (51) onto the conveyor belt (5) and is transported by the conveyor belt (5) to the next process to complete the automated peeling operation.
