Description

Technical Field

[0001] The present invention relates to the field of processing of pomegranate fruits for peeling and removing the pulp, and more particularly to a pomegranate fruit peeling and pulp removing device capable of batch processing of pomegranate fruits. Background Art

[0002] The appearance of a pomegranate fruit is nearly spherical. The mature pomegranate peel is bright red or pink. The peel wraps layer upon layer of fruit grains and seeds, and these fruit grains and seeds are the pulp of the pomegranate. Among them, the pulp of the pomegranate is sweet and sour, juicy, rich in fruit sugars, high-quality proteins, easily absorbable fats, etc., and has high nutritional value. The peel of the pomegranate contains pomegranate peel alkaloid, which can play a role in expelling insects and has certain medicinal value.

[0003] Therefore, to maximize the nutritional and medicinal values of pomegranate fruits, it is necessary to separate the peel and the pulp of the pomegranate fruit. When performing the operation of separating the peel and the pulp of the pomegranate fruit, if the manual operation method is adopted, not only is the labor intensity high, the labor cost is high, but also the operation efficiency is low, and the operation quality is difficult to guarantee. Especially in the case of batch processing of pomegranate fruits, for example, when using the pulp of pomegranate fruits for juice extraction, the demand for the pulp is relatively large, and the manual operation method obviously cannot meet the demand for batch processing of pomegranate fruits. If a conventional peeling machine is used to batch process pomegranate fruits, although it can partially replace manual labor and reduce part of the labor intensity, however, in the actual processing process, it is easy to cause the mixing of the peel and the pulp, and even after the pulp is batch-damaged and mixed with the peel to form a paste-like mixture, which seriously reduces the separation operation efficiency and operation quality of the peel and the pulp, and instead increases the separation cost of the peel and the pulp. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: aiming at the problems existing in the prior art, to provide a pomegranate fruit peeling and pulp removing device to improve the separation operation efficiency of the peel and the pulp.

[0005] The technical problem to be solved by the present invention is realized by adopting the following technical solutions: a pomegranate fruit peeling and pulp removing device, including a working station turntable mechanism, a cutting head and skinning mechanism, and a spreading and knocking mechanism. A clamping jaw is installed on the working station turntable mechanism, a cutting knife and an elastic skinning knife holder are installed on the cutting head and skinning mechanism, a plurality of skinning knives are installed on the elastic skinning knife holder, and a spreading piece and an elastic knocking rod are installed on the spreading and knocking mechanism; when performing the operation of peeling and removing the pulp of the pomegranate fruit, the clamping jaw fixes the pomegranate fruit, first the calyx tube of the pomegranate is removed by the cutting knife, and at the same time the surface of the pomegranate fruit is divided into several petals by the skinning knife, then the surface of the pomegranate fruit is spread open from the incision part of the calyx tube by the spreading piece, and finally the pomegranate fruit is knocked by the elastic knocking rod until the pulp is separated from the peel.

[0006] Further, the cutting knife is driven by a cutting cylinder. The elastic skin-cutting knife holder is connected to a skin-cutting push rod. One end of the action output end of the cutting cylinder forms a rotatable connection structure with one end of a skin-cutting connecting rod, and the other end of the skin-cutting connecting rod forms a rotatable connection structure with a skin-cutting cam. When the cutting cylinder drives the cutting knife to move horizontally to remove the pomegranate calyx tube, the skin-cutting connecting rod drives the skin-cutting cam to rotate synchronously. During the rotation of the skin-cutting cam, the skin-cutting cam drives the skin-cutting push rod to move vertically downward relative to the cutting knife, and the skin-cutting push rod drives the elastic skin-cutting knife holder to move vertically downward synchronously until the skin-cutting knife divides the pomegranate fruit skin into several petals.

[0007] Further, the spreading piece is installed on a spreading plate. A guide sliding column is formed at the bottom of the spreading plate, and a relative radial sliding connection structure is formed between the spreading plate and a limit cover plate. A relative rotational connection structure is formed between the limit cover plate and a rotating disk. An arc-shaped guide chute is provided on the rotating disk, and a sliding fit structure is formed between the guide chute and the guide sliding column. When the rotating disk rotates, the guide sliding column drives the spreading plate to slide radially relative to the limit cover plate.

[0008] Further, one end of the elastic knocking rod forms a rotatable connection structure with one end of a sliding rod, the other end of the sliding rod forms a rotatable connection structure with one end of a linkage rod, and the other end of the linkage rod forms a rotatable connection structure with a crank. When the crank rotates, the sliding rod is driven by the linkage rod to perform a reciprocating linear motion, and the sliding rod drives the elastic knocking rod to perform a synchronous reciprocating linear motion.

[0009] Further, the elastic knocking rod penetrates through a movable seat. A relative rotational connection structure is formed between the movable seat and a positioning seat, and the elastic knocking rod moves radially relative to the sliding rod under the drive of the sliding rod.

[0010] Further, the clamping jaws are fixedly installed on the outer circumferential part of an annular cam. A fixed connection structure is formed between the annular cam and a lower ratchet through an assembly seat, and a ratchet and pawl transmission mechanism is formed between the lower ratchet and a lower pawl.

[0011] Further, a fixed connection structure is formed between the assembly seat and an upper ratchet, and a ratchet and pawl braking mechanism is formed between the upper ratchet and an upper pawl.

[0012] Further, a flow-limiting discharging mechanism is further included. The flow-limiting discharging mechanism includes a flow-limiting pipeline, and the flow-limiting pipeline is respectively connected to an upper baffle plate and a sliding lower baffle plate. The sliding lower baffle plate is driven by a discharging push rod and rotates relative to the flow-limiting pipeline within a certain rotation angle range.

[0013] Further, it further includes an alignment and indexing mechanism. The alignment and indexing mechanism includes a tray, its driving mechanism, and two alignment rollers arranged side by side and in parallel. The two alignment rollers are respectively connected to the roller seats in a rotatable connection structure, and each alignment roller is fixedly connected to an independent gear. The independent gears are all engaged with a driving gear to form a gear transmission mechanism. The tray is arranged between the two alignment rollers, and the tray makes a spiral lifting motion relative to the alignment rollers through its driving mechanism.

[0014] Further, it further includes an alignment and indexing mechanism. The alignment and indexing mechanism includes a suction cup, a transposition connecting rod, and its driving mechanism. The suction cup is installed at one end of a suction cup holder. A guide pin is formed at the other end of the suction cup holder. A sleeve structure with a relative linear sliding motion is formed between the suction cup holder and a transposition sleeve. A second guide groove is opened on the side of the transposition sleeve. A rotatable connection structure with a relative rotation is formed between the transposition sleeve and a transposition guide rail. A transposition guide groove is formed on the transposition guide rail. A first guide groove is opened on the transposition connecting rod. The guide pin movably penetrates through the second guide groove, the transposition guide groove, and the first guide groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: When performing the operation of peeling and removing the pulp of pomegranate fruits, first fix the pomegranate fruit with the clamping jaws, and then use the horizontal movement of the cutting knife to remove the pomegranate calyx tube. At the same time, the pomegranate fruit skin can be divided into several petals by the skin-cutting knife. After the spreading piece spreads the pomegranate fruit skin from the incision of the pomegranate calyx tube, the pomegranate fruit can be knocked by the elastic knocking rod, so that the pulp of the pomegranate fruit and the peel are automatically separated under the action of the elastic knocking force without damaging the pulp. The entire separation operation process does not require excessive manual operations and can also achieve continuous batch operations, which not only improves the separation operation efficiency and quality of the pomegranate fruit peel and pulp, but also greatly reduces the labor intensity.

Detailed implementation manners

[0045] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0046] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 15The pomegranate fruit peeling and flesh-taking device shown includes a conveying and feeding mechanism 1 and a frame 9. A shunting funnel 8, a restricted outflow and discharging mechanism 2, an alignment and rotation mechanism 3, a cutting head and skinning mechanism 4, a spreading and knocking mechanism 5, a separation and collection mechanism 6, and a station turntable mechanism 7 are installed on the frame 9. Among them, the specific structure of the restricted outflow and discharging mechanism 2 is as follows Figure 4 , Figure 5 , Figure 6 , Figure 7 shown, mainly including a restricted flow pipe 21 and a discharging push rod 25. The restricted flow pipe 21 is respectively connected to an upper baffle 22 and a sliding lower baffle 23. The discharging push rod 25 passes through a limit sleeve 24 and forms a movable connection structure with relative sliding with the limit sleeve 24. The limit sleeve 24 is fixedly connected to the frame 9. The sliding lower baffle 23 is driven by the discharging push rod 25 and rotates relative to the restricted flow pipe 21 within a certain angular range. The discharging push rod 25 is driven by a convex tooth 72 on an annular cam 71 and makes a vertical linear motion relative to the limit sleeve 24.

[0047] When the annular cam 71 rotates, the convex tooth 72 on it pushes the discharging push rod 25 to move vertically upward relative to the limit sleeve 24. Under the push of the discharging push rod 25, the sliding lower baffle 23 and the upper baffle 22 are simultaneously lifted in the restricted flow pipe 21. Among them, when the upper baffle 22 is lifted, the pomegranate fruit in front can pass through. When the sliding lower baffle 23 is lifted, the pomegranate fruit behind can be blocked from passing through. Thus, one pomegranate fruit can be controlled to fall and discharge each time, so as to realize the sequential and orderly discharging of pomegranate fruits.

[0048] The alignment and rotation mechanism 3 includes an alignment mechanism and a rotation mechanism. The specific structure of the alignment mechanism is as follows Figure 8 , Figure 9 , Figure 10 shown, mainly including alignment rollers 302 and their driving mechanism, and a tray 316 and its driving mechanism. Two alignment rollers 302 are provided and arranged in a side-by-side parallel manner. An inwards concave arc surface structure is formed on the outer surface of the alignment rollers 302. The two alignment rollers 302 respectively form a movable connection structure with relative rotation with a roller seat 317, and the inwards concave arc surfaces on the alignment rollers 302 are arranged oppositely. Each alignment roller 302 is respectively fixedly connected to an independent gear, and the independent gears are all engaged with a driving gear 318 to form a gear meshing transmission mechanism. The driving mechanism of the alignment rollers 302 uses an alignment motor 301. The alignment motor 301 drives the driving gear 318 to rotate. When the driving gear 318 rotates, it drives the two alignment rollers 302 to rotate synchronously, so as to align the posture of the pomegranate fruit between the two alignment rollers 302.

[0049] The described tray 316 is fixedly installed at the top end of the tray ejector rod 303, and the tray 316 is arranged between two alignment rollers 302. The tray ejector rod 303 penetrates through the alignment sleeve 304 and forms a clearance fit structure with the alignment sleeve 304. The alignment sleeve 304 is fixedly connected to the frame 9. A guide push column 315 is formed on the tray ejector rod 303, and a third guide groove 321 with a spiral structure is formed on the alignment sleeve 304. A sliding fit structure is formed between the guide push column 315 and the third guide groove 321. The driving mechanism of the tray 316 includes an alignment cylinder 314. The action output end of the alignment cylinder 314 is connected to the tray ejector rod 303 through a bearing (not shown in the figure). Therefore, when the alignment cylinder 314 drives the tray ejector rod 303 to perform a lifting motion, the guide push column 315 slides along the spiral third guide groove 321, so that the tray ejector rod 303 can rotate relative to the alignment sleeve 304 while performing a lifting motion relative to the alignment cylinder 314, thereby enabling the tray 316 to perform a spiral lifting motion relative to the alignment rollers 302 under the drive of the alignment cylinder 314. It should be noted that the spiral lifting motion here means that the tray 316 is performing a linear lifting motion relative to the alignment rollers 302 while rotating relative to the alignment rollers 302.

[0050] When the pomegranate fruit is straightened by the straightening roller 302, it is necessary to ensure that the pomegranate calyx tube at the head of the pomegranate fruit points to the straightening motor 301, so as to ensure the reliability and quality of the subsequent operations such as cutting, peeling, opening, and knocking of the pomegranate fruit. For this reason, a light sensor (not shown) can be added to the roller seat 317, and the light sensor is electrically connected to the PLC or the single-chip microcomputer, and the PLC or the single-chip microcomputer is electrically connected to the straightening cylinder 314. When the pomegranate fruit falls into the tray 316 from the discharge port of the current limiting pipeline 21, the straightening motor 301 is started, and drives the two straightening rollers 302 to rotate, and the pomegranate fruit rolls repeatedly under the action of the straightening roller 302, and the light sensor detects and identifies the pomegranate calyx tube at the head of the pomegranate fruit, and outputs the corresponding identification electrical signal to the PLC or the single-chip microcomputer. When the pomegranate calyx tube at the head of the pomegranate fruit points to the alignment motor 301, the PLC or single-chip microcomputer controls the alignment cylinder 314 to not move, indicating that the posture of the pomegranate fruit does not need to be adjusted and aligned; however, when the pomegranate calyx tube at the head of the pomegranate fruit faces away from the alignment motor 301, the PLC or single-chip microcomputer controls the alignment cylinder 314 to move, and the alignment cylinder 314 drives the tray push rod 303 to move upward, and the guide push column 315 will slide upward synchronously along the third guide groove 321 of the spiral structure. At the same time, the tray push rod 303 drives the tray 316 to rotate 180° relative to the alignment sleeve 304, and the tray 316 completes the two actions of rising and rotating at the same time, so that the pomegranate fruit can be lifted up and disengaged from the alignment roller 302. At the same time, the pomegranate fruit can also be rotated 180°, so that the pomegranate calyx tube at the head of the pomegranate fruit points to the alignment motor 301 again, and at this time, the posture alignment and adjustment effect of the pomegranate fruit is achieved.

[0051] The specific structure of the transposition mechanism is as follows: Figure 11 , Figure 12 , Figure 13 , Figure 14As shown in the figure, it mainly includes a suction cup 305, a transposition connecting rod 307 and its driving mechanism. The suction cup 305 is preferably a negative pressure suction cup and is installed at one end of the suction cup holder 309. A guide sliding pin 312 is formed at the other end of the suction cup holder 309. A sleeve structure with relative linear sliding is formed between the suction cup holder 309 and the transposition sleeve 308. A second guide groove 320 is opened on the side of the transposition sleeve 308. An activity connection structure with relative rotation is formed between the transposition sleeve 308 and the transposition guide rail 310. The transposition guide rail 310 is fixedly connected to the transposition support 313, and a transposition guide groove 311 is formed on the transposition guide rail 310. Preferably, the transposition guide groove 311 includes a vertical section 311a, an inclined section 311b and a horizontal section 311c, and the vertical section 311a, the inclined section 311b and the horizontal section 311c are connected in sequence and penetrate through to form a V-shaped structure guide groove. A first guide groove 319 is opened on the transposition connecting rod 307. The guide sliding pin 312 movably penetrates through the second guide groove 320, the transposition guide groove 311 and the first guide groove 319. The driving mechanism of the transposition connecting rod 307 uses a transposition cylinder 306. An activity connection structure with relative rotation is formed between the action output end of the transposition cylinder 306 and the transposition connecting rod 307. An activity connection structure with relative rotation is also formed between the other end of the transposition cylinder 306 and the transposition support 313.

[0052] When the transposition mechanism works, after the suction cup 305 sucks and fixes the pomegranate fruit in the horizontal state, the transposition cylinder 306 drives the transposition connecting rod 307 to rotate counterclockwise relative to the transposition support 313. As a result, the guide sliding pin 312 slides along the horizontal section 311c of the transposition guide groove 311. The guide sliding pin 312 drives the suction cup holder 309 to slide backward relative to the transposition sleeve 308, as Figure 12 shown. When the suction cup holder 309 slides backward relative to the transposition sleeve 308 and gets stuck at the bottom of the transposition sleeve 308, at this time, the transposition sleeve 308 and the suction cup holder 309 form a whole. The transposition cylinder 306 drives the transposition connecting rod 307 to continue rotating counterclockwise relative to the transposition support 313, and makes the guide sliding pin 312 slide along the inclined section 311b of the transposition guide groove 311. During this process, the whole of the transposition sleeve 308 and the suction cup holder 309 will rotate counterclockwise relative to the transposition guide rail 310, as Figure 13 shown. When the whole of the transposition sleeve 308 and the suction cup holder 309 rotates counterclockwise relative to the transposition guide rail 310 by 90° and gets stuck, then, the transposition cylinder 306 drives the transposition connecting rod 307 to continue rotating counterclockwise relative to the transposition support 313. As a result, the guide sliding pin 312 can slide along the vertical section 311a of the transposition guide groove 311. During this process, the suction cup holder 309 extends out relative to the transposition sleeve 308, as Figure 14 shown, thus completing the transposition action of the pomegranate fruit to ensure that the pomegranate calyx tube at the head of the pomegranate fruit is always downward during the subsequent processing process.

[0053] As Figure 15 、 Figure 16 、 Figure 17 shown, the cutting and peeling mechanism 4 mainly includes a cutting knife 42 and a peeling knife 49. The cutting knife 42 is driven by a cutting and peeling cylinder 48. The cutting and peeling cylinder 48 is installed on a cutting and peeling bracket 41, and the action output end of the cutting and peeling cylinder 48 forms a movable connection structure with relative rotation with one end of a peeling connecting rod 47. The other end of the peeling connecting rod 47 forms a movable connection structure with relative rotation with a peeling cam 46. A plurality of peeling knives 49 are provided and are all installed on an elastic peeling knife holder 43. The elastic peeling knife holder 43 is connected to a peeling push rod 45, as Figure 18 shown.

[0054] When the cutting and peeling mechanism 4 works, the cutting and peeling cylinder 48 first drives the cutting knife 42 to move horizontally to remove the calyx tube at the head of the pomegranate fruit. At the same time, the peeling cam 46 is driven to rotate synchronously through the peeling connecting rod 47. During the rotation of the peeling cam 46, the peeling push rod 45 is driven to move vertically downward relative to the cutting knife 42. The elastic peeling knife holder 43 is driven by the peeling push rod 45 to move vertically downward synchronously. During the continuous pressing of the peeling push rod 45, through the adaptive clamping action of the elastic peeling knife holder 43 and the cutting action of the peeling knife 49, the epidermis of the pomegranate fruit can be divided into several petals while keeping the root epidermis intact. Subsequently, the cutting and peeling cylinder 48 retracts until the cutting knife 42 and the peeling knife 49 are reset, completing the cutting and peeling operation of the pomegranate fruit. In order to ensure the operation quality of the cutting and peeling operation, the peeling push rod 45 can be movably penetrated through a peeling limit seat 44, and the peeling limit seat 44 is fixedly connected to the cutting and peeling bracket 41.

[0055] As Figure 19 、 Figure 20 shown, the spreading and knocking mechanism 5 is installed on a spreading and knocking bracket 501 and mainly includes a spreading mechanism and a knocking mechanism. The spreading mechanism is installed on the spreading and knocking bracket 501 through a fixed chassis 520, as Figure 20 、 Figure 21As shown. The expansion mechanism mainly includes a number of expansion pieces 519, and the number of expansion pieces 519 forms an annular structure. The expansion pieces 519 are respectively installed on independent expansion plates 509 one by one. A guide slide column 517 is formed at the bottom of the expansion plate 509, and a relative radial sliding movable connection structure is formed between the expansion plate 509 and the limit cover plate 510. A relative rotational movable connection structure is formed between the limit cover plate 510 and the rotating disk 516. An arc-shaped guide chute 518 is opened on the rotating disk 516, and a sliding fit structure is formed between the guide chute 518 and the guide slide column 517. The rotating disk 516 is connected to the action output end of the expansion push rod 502 and the expansion cylinder 503, and the rotating disk 516 is driven to rotate by the expansion cylinder 503. When the rotating disk 516 rotates, the guide slide column 517 drives the expansion plate 509 to slide radially relative to the limit cover plate 510, as Figure 21 shown, so that a number of expansion pieces 519 can move radially relative to the fixed chassis 520 and open or close in an annular shape.

[0056] As Figure 20 , Figure 22 shown, the knocking mechanism mainly includes a number of elastic knocking rods 508, and the number of elastic knocking rods 508 forms an annular structure. A relative rotational movable connection structure is formed between one end of the elastic knocking rod 508 and the sliding rod 507. A relative rotational movable connection structure is formed between the other end of the sliding rod 507 and one end of the linkage rod 504. A relative rotational movable connection structure is formed between the other end of the linkage rod 504 and the crank 506. The crank 506 is driven by the knocking motor 505, and the knocking motor 505 is installed on the expansion knocking bracket 501. When the crank 506 rotates, the sliding rod 507 is driven to perform a reciprocating linear motion through the linkage rod 504, and the sliding rod 507 drives the elastic knocking rod 508 to perform a synchronous reciprocating linear motion.

[0057] When the expansion knocking mechanism 5 works, first, when a number of expansion pieces 519 are in an annular closed state, the expansion pieces 519 are inserted from the incision part of the head of the pomegranate fruit. Then, the rotating disk 516 is driven to rotate by the expansion cylinder 503, and the expansion plate 509 is driven to slide radially outwards through the guide slide column 517, so that a number of expansion pieces 519 can move radially outwards synchronously and gradually open in an annular shape, so that a number of expansion pieces 519 can open the pomegranate fruit skin to a certain angle at the incision part of the head of the pomegranate fruit. Finally, the knocking motor 505 is started, and the sliding rod 507 is driven to perform a reciprocating linear motion up and down through the crank 506 and the linkage rod 504, and the pomegranate fruit is knocked by the elastic knocking rod 508 swinging back and forth, so that the pulp of the pomegranate fruit can be separated from the peel.

[0058] In order to improve the efficiency of separating the pulp and peel of the pomegranate fruit and ensure the quality of the pulp after separation, the elastic knocking rod 508 can be passed through the movable seat 514, and the sliding rod 507 can be passed through the knocking limit seat 511, the knocking limit seat 511 is fixedly connected to the open knocking bracket 501, and a relatively rotatable movable connection structure is formed between the movable seat 514 and the positioning seat 513, and the positioning seat 513 is fixedly connected to the knocking limit seat 511 through the positioning rod 512. The elastic knocking rod 508 moves radially relative to the sliding rod 507 under the drive of the sliding rod 507, and a knocking ball 515 is set at the tail end of the elastic knocking rod 508. Figure 22 As shown, the knocking ball 515 can be used to knock and thresh the pomegranate fruit, so that the pulp and peel of the pomegranate fruit are separated.

[0059] The specific structure of the separation and collection mechanism 6 is as follows: Figure 23 , Figure 24 , Figure 25 As shown, it mainly includes a peel and pulp collection tube 63, a pulp collection box 61 and a peel collection box 64. The bottom of the peel and pulp collection tube 63 is provided with a filter screen 65 of an inclined structure, and the inner cavity of the peel collection box 64 is provided with a screen 62. When the elastic knocking rod 508 is working, the pulp and peel falling off the pomegranate fruit enter the peel and pulp collection tube 63, and are first screened by the filter screen 65. The screened pulp passes through the filter screen 65 and falls into the pulp collection box 61. After the pulp separation is completed, the clamping jaws 73 are released, and the remaining pomegranate peels together with a small amount of residual pulp and other mixtures enter the peel collection box 64 and are screened again by the screen screen 62. The pulp after the second screening passes through the screen screen 62 and falls into the pulp collection box 61, and the screened peels are left in the peel collection box 64 for collection.

[0060] like Figure 5 , Figure 26 , Figure 27 , Figure 28 As shown, the station turntable mechanism 7 mainly includes an annular cam 71 and a driving mechanism thereof. A plurality of continuous convex teeth 72 are formed on the annular cam 71. A plurality of clamps 73 are fixedly installed on the outer circumference of the annular cam 71. The clamps 73 are preferably cylinder clamps. A fixed connection structure is formed between the annular cam 71 and the lower ratchet 70 through an assembly seat 74. A ratchet-pawl transmission mechanism is formed between the lower ratchet 70 and the lower pawl 79. The lower pawl 79 is driven by a lower cylinder 76. Furthermore, a fixed connection structure is formed between the assembly seat 74 and the upper ratchet 75. A ratchet-pawl braking mechanism is formed between the upper ratchet 75 and the upper pawl 77. The upper pawl 77 is driven by an upper cylinder 78 to prevent the annular cam 71 from rotating after rotation, thereby ensuring the stability and reliability of the annular cam 71 after rotation.

[0061] It should be noted that in order to improve the overall processing efficiency of the present invention and further reduce the processing cost of pomegranate fruit, several sets of independent processing modules can be added, and the several sets of independent processing modules are evenly distributed around the station turntable mechanism 7, thereby forming a circular circulation station layout, such as Figure 2 As shown. Each set of independent processing modules is composed of the above-mentioned flow-limiting discharge mechanism 2, the straightening and rotating mechanism 3, the head cutting and peeling mechanism 4, the opening and beating mechanism 5 and the separation and collection mechanism 6. Correspondingly, a corresponding number of output ports need to be opened on the diversion funnel 8. Among them, when each set of independent processing modules is peeling and taking out the pomegranate fruit, first, the conveying and feeding mechanism 1 outputs the pomegranate fruit to be processed in batches to the diversion funnel 8, and the pomegranate fruit in the diversion funnel 8 will be diverted through the output port to the flow-limiting pipe 21 in the corresponding flow-limiting discharge mechanism 2. The discharge push rod 25 is driven by the convex teeth 72 on the annular cam 71, and the discharge of the pomegranate fruit in the flow-limiting pipe 21 can be controlled to ensure that the discharge ports of the flow-limiting pipe 21 are in order, and one pomegranate fruit is released each time to enter the subsequent straightening and rotating mechanism 3. When the pomegranate fruit falls onto the tray 316 in the aligning and shifting mechanism 3 , the aligning roller 302 and the aligning cylinder 314 align the posture of the pomegranate fruit on the tray 316 .

[0062] After the pomegranate fruit is adjusted and sucked by the suction cup 305 and rotated 90°, it is clamped and fixed by the clamping claw 73. The pomegranate fruit fixed by the clamping claw 73 rotates a certain angle synchronously with the rotation of the station turntable mechanism 7, so as to transfer the pomegranate fruit to the next station cutting and peeling mechanism 4; because the clamping claw 73 fixes the pomegranate fruit, the pomegranate calyx tube is first removed by the cutting knife 42, and the skin of the pomegranate fruit is divided into several petals by the peeling knife 49, and the root is not cut off to ensure that the pomegranate fruit is not broken; then, the station turntable mechanism 7 continues to rotate a certain angle, and the pomegranate fruit that has been cut and peeled is transferred to the next station to open and knock the mechanism 5.

[0063] At the spreading and knocking working station, first, the spreading piece 519 inserts into the cut part of the pomegranate fruit at the calyx tube of the pomegranate fruit with petals cut and slightly spreads the epidermis of the pomegranate fruit at a certain angle. Then, the elastic knocking rod 508 above reciprocally knocks the already spread epidermis of the pomegranate fruit until the pulp is separated from the peel, and the separated pulp drops into the separation and collection mechanism 6 below for collection. When the separation of the pulp of the pomegranate fruit is completed, the clamping jaw 73 is released, and the remaining pomegranate peel falls into the separation and collection mechanism 6 below for collection, thus completing the operation of peeling and removing the pulp of the pomegranate fruit. Subsequently, the working station turntable mechanism 7 continues to rotate by a certain angle and transfers the empty clamping jaw 73 to the alignment and indexing mechanism 3 in another set of processing modules so that the clamping jaw 73 can clamp the next pomegranate fruit with its posture adjusted. By repeating this cycle, the operation of peeling and removing the pulp of a batch of pomegranate fruits can be carried out, greatly improving the processing efficiency and reducing the processing cost of pomegranate fruits.

[0064] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. It should be noted that any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
