Description

Technical Field

[0001] This invention belongs to the field of fruit shell cutting technology, specifically an automatic cutting device for processing macadamia nuts. Background Technology

[0002] Macadamia nuts, as a high-value nut, require slots to be cut into their hard shells during processing to allow seasonings to penetrate and for consumers to eat. Current macadamia nut cutting devices are mostly simple cutting mechanisms, but they often suffer from low automation, insufficient cutting precision, and low efficiency, leading to inconsistent processing quality and resource waste.

[0003] In the prior art, a typical macadamia nut opening device, such as the one disclosed in CN107752820B, achieves nut fixing and cutting through a cylinder, a lower pressure plate, and a cutting assembly. This device employs a double-layer cutting blade design, aiming to create two slots to avoid the problem of the nut splitting in half, thereby improving the eating experience. Components include a frame, a cutting assembly, and a guide seat.

[0004] However, this device still has significant drawbacks. First, its feeding and positioning rely on manual operation. The lower pressure plate pushes the fruit in the fruit-holding trough via a cylinder, but the lack of a continuous automated feeding system results in low processing efficiency and makes it difficult to meet the needs of large-scale production. Second, the motion control of the cutting component is relatively complex. The cutting component relies on a lead screw, a contour wheel, and a spring to adjust the cutting depth, but this design is easily affected by variations in fruit size, leading to inconsistent cut depths and even damage to the kernel. In addition, the existing device does not securely fix the fruit. Although the bottom surface of the fruit-holding trough has friction textures, the fruit is prone to slipping during high-speed cutting, affecting the cutting accuracy. Although the cooperation between the contour wheel and the contour base has been demonstrated, the vibration problem during fruit positioning has not been solved. More importantly, the existing technology mainly focuses on the number of slots (double-layer cutting) to avoid splitting, but ignores the overall automated process, such as the continuity of feeding, positioning, and unloading, which limits production efficiency and reliability.

[0005] In summary, existing macadamia nut cutting devices have significant shortcomings in terms of automation, precision, and efficiency, necessitating a solution that integrates automatic feeding, precise positioning, and efficient cutting. This invention aims to overcome these deficiencies by improving processing quality and throughput through innovative structural design. Therefore, this invention provides an automatic cutting device for macadamia nut processing. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: An automatic cutting device for processing macadamia nuts according to the present invention includes a base plate and a feeding slide rail, a hydraulic cylinder, a cutting module, and a positioning box mounted on the base plate; the positioning box is fixed to one end of the base plate, the hydraulic cylinder is fixed to the other end of the base plate, the feeding slide rail is arranged between the hydraulic cylinder and the positioning box, and the outlet end of the feeding slide rail is connected to the feeding end of the positioning box; the cutting module is arranged at one end of the base plate and is located directly above the positioning box.

[0008] The positioning box is used to carry the fruit to be processed, and a baffle is fixedly connected inside the positioning box. Several sliding rods are slidably connected to the baffle. When the fruit to be processed enters the positioning box from the feeding slide rail, the fruit to be processed squeezes the sliding rods, causing the sliding rods to generate relative displacement on the baffle.

[0009] The cutting module includes a mounting plate, a servo motor, and a saw blade fixed to the output end. The output end of the servo motor passes through the side wall of the mounting plate, and the output end of the servo motor is also rotatably connected to a limit rod. The limit rod is fixed to the side wall of the mounting plate, and a guide rod is vertically connected through the limit rod. When the cutting module slides from one side of the positioning box to the other side, the guide rod and the slide bar slide together to drive the axial displacement of the mounting plate and the saw blade to adapt to the shape of the fruit to be processed.

[0010] Preferably, the positioning box has an open slot at one end adjacent to the feeding slide rail, and an abutment slot at the other end of the positioning box. The baffle is fixed to the bottom surface of the abutment slot. A fitting block is fixed between two adjacent positioning boxes, and a guide mold is fixed to the fitting block. A low-position slot is opened at the top of the guide mold, and fitting slots are opened on both sides of the guide mold.

[0011] Preferably, the cutting module further includes a tool slide rail, in which a slider is slidably connected. A lead screw is threaded into the middle of the slider. An oblong groove is formed on the bottom side wall of the slider. A support rod is fixedly connected to the top of the mounting plate. The support rod passes through the bottom of the slider, and a positioning pin is connected through the top of the support rod. The positioning pin passes through the oblong groove. A third spring is sleeved on the support rod, and the two ends of the third spring abut against the slider and the mounting plate.

[0012] Preferably, a top partition is fixed to the middle surface of the base plate, the output end of the hydraulic cylinder passes through the top partition and the feeding slide rail, and the output end of the hydraulic cylinder is connected to an abutment part via a spline. A third sliding groove is provided on the abutment part, and an abutment rod is slidably connected in the abutment part. A first spring is fixed between one end of the abutment rod located in the abutment part and the bottom surface of the abutment part. When the output end of the hydraulic cylinder outputs, it drives the abutment part to pass through the feeding slide rail, and pushes the fruit to be processed carried at the outlet end of the feeding slide rail into the positioning box based on the abutment rod, while applying pressure to the fruit to be processed.

[0013] Preferably, the hydraulic cylinder has a second sliding groove in the middle, and an abutment part is slidably connected in the second sliding groove. The abutment part is located between the feed slide rail and the top partition plate. When the output end of the hydraulic cylinder outputs, the feed slide rail is driven to slide on the bottom plate through the abutment part and the second sliding groove, so that the outlet end of the feed slide rail is connected to the open groove of the positioning box.

[0014] Preferably, the bottom surface of the open slot of the positioning box is provided with a relief groove, and the outlet end of the feeding slide rail is hinged with a baffle plate relative to the relief groove. When the fruit to be processed slides from the top of the feeding slide rail to the outlet end of the feeding slide rail, it is blocked by the baffle plate and temporarily stored at the outlet end of the feeding slide rail. When the contact part penetrates the feeding slide rail and applies pressure to the fruit to be processed, the fruit to be processed squeezes the baffle plate, causing the baffle plate to embed into the relief groove, and the fruit to be processed is pushed into the positioning box.

[0015] Preferably, the base plate has an open slot adjacent to the positioning box body with a discharge port and a first sliding groove, and the discharge port is connected to the first sliding groove; the bottom of the feeding slide rail is fixedly connected to a connecting plate, and the connecting plate is slidably connected in the first sliding groove. When the fruit to be processed is completed, the output end of the hydraulic cylinder retracts, the feeding slide rail retracts, and the guide rod drives the fruit to be processed to exit from the open slot of the positioning box body and be discharged through the discharge port.

[0016] Preferably, a bottom partition is fixedly connected to the bottom surface of the middle part of the bottom plate, a connecting rod is fixedly connected to the connecting plate, and the connecting rod passes through the bottom partition. A second spring is sleeved on the connecting rod. The second spring is used to drive the feeding slide rail to retract under no external force, thereby exposing the discharge port on the bottom plate.

[0017] Preferably, a hopper is fixedly connected to the bottom surface of the base plate corresponding to the discharge port to guide the processed fruit discharged through the discharge port, and a fixing frame is fixedly connected to the surface of the base plate, with the tool slide rail fixedly connected to the bottom of the fixing frame.

[0018] Preferably, a counterweight is fixed to the top of the guide rod to drive the guide rod to always smoothly contact the low-position groove.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The automatic cutting device for processing macadamia nuts of the present invention uses a hydraulic cylinder to apply pressure to the nuts to be processed, causing the nuts to be processed to slide out of the positioning box by squeezing a sliding rod. The cutting module then uses a guide rod in a sliding engagement with the sliding rod in the positioning box to accurately fit each nut in the positioning box. This allows the cutting module to adaptively cut according to the shape of the nut, avoiding cutting into the flesh and thus preventing damage to the flesh after cutting. This achieves automated feeding and positioning. Through the cooperation of the sliding rod and the guide rod, the cutting depth adapts to the size of the nut, avoiding damage to the flesh, improving cutting accuracy and consistency. The overall structure is compact, supports continuous processing, and improves efficiency.

[0021] 2. The automatic cutting device for processing macadamia nuts according to the present invention drives the nuts to be processed into the positioning box through the contact part, and fixes the nuts to be processed in the positioning box based on the continuously applied pressure, and indirectly applies pressure to the slide rods based on the nuts to be processed, so that several slide rods slide relative to the baffle. When the contact part retracts, the return spring and the slide rods drive the nuts to be processed out of the positioning box, and provide the power to drive the nuts to be processed from the positioning box to the discharge port, realizing the continuous action of feeding the nuts to be processed and automatically discharging them after processing. Then, based on the second spring, an automatic reset force is provided to ensure that the feeding slide rail returns to its position in time, exposing the discharge port for discharge, thereby enhancing the degree of automation.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] like Figures 1 to 10 As shown in the embodiment of the present invention, an automatic cutting device for processing macadamia nuts includes a base plate 1 and a feeding slide rail 3, a hydraulic cylinder 2, a cutting module 6, and a positioning box 4 mounted on the base plate 1. The positioning box 4 is fixed to one end of the base plate 1, the hydraulic cylinder 2 is fixed to the other end of the base plate 1, the feeding slide rail 3 is arranged between the hydraulic cylinder 2 and the positioning box 4, and the outlet end of the feeding slide rail 3 is connected to the feeding end of the positioning box 4. The cutting module 6 is arranged at one end of the base plate 1 and is located directly above the positioning box 4.

[0036] The positioning box 4 is used to carry the fruit to be processed 5, and a baffle 43 is fixedly connected inside the positioning box 4. Several sliding rods 47 are slidably connected on the baffle 43. When the fruit to be processed 5 enters the positioning box 4 from the feeding slide rail 3, the fruit to be processed 5 squeezes the sliding rods 47, causing the sliding rods 47 to generate relative displacement on the baffle 43.

[0037] The cutting module 6 includes a mounting plate 64, a servo motor 65, and a saw blade 66 fixed to the output end. The output end of the servo motor 65 passes through the side wall of the mounting plate 64, and the output end of the servo motor 65 is also rotatably connected to a limit rod 67. The limit rod 67 is fixed to the side wall of the mounting plate 64, and a guide rod 68 is vertically connected through the limit rod 67. When the cutting module 6 slides from one side of the positioning box 4 to the other side, the guide rod 68 slides in cooperation with the slide rod 47 to drive the mounting plate 64 and the saw blade 66 to move axially to adapt to the shape of the fruit 5 to be processed.

[0038] In existing technologies, feeding and positioning rely on manual operation. The lower pressure plate pushes the fruit in the fruit-holding trough through a cylinder, but the lack of a continuous automated feeding system leads to low processing efficiency and makes it difficult to meet the needs of large-scale production. Secondly, the motion control of the cutting component is relatively complex. The cutting component relies on a lead screw, a contour wheel, and a spring to adjust the cutting depth, but this design is easily affected by variations in fruit size, resulting in inconsistent cut depths and even damage to the kernel. In addition, the existing device does not securely fix the fruit. Although the bottom surface of the fruit-holding trough is equipped with friction textures, the fruit is prone to slipping during high-speed cutting, affecting the cutting accuracy. Although the cooperation between the contour wheel and the contour base is demonstrated, the vibration problem during fruit positioning is not solved. More importantly, existing technologies mainly focus on the number of slots (double-layer cutting) to avoid splitting, but neglect the overall automated process, such as the continuity of feeding, positioning, and unloading, which limits production efficiency and reliability.

[0039] In one embodiment of the present invention, after the fruit to be processed 5 is sorted by size, it is fed into the feeding slide rail 3 by an external sorting device. The fruit to be processed 5, once inside the feeding slide rail 3, slides from the top to the outlet end. The outlet end of the feeding slide rail 3 then feeds the fruit to be processed 5 into the positioning box 4. Subsequently, the hydraulic cylinder 2 outputs power, with its output end abutting against the side wall of the fruit to be processed 5 inside the positioning box 4. This causes both sides of the fruit to be processed 5 to abut against the inner side wall of the positioning box 4 and the output end of the hydraulic cylinder 2, respectively, thus fixing the fruit to be processed 5 inside the positioning box 4 and ensuring its stability during the cutting process. When the fruit to be processed 5 abuts against the inside of the positioning box 4, it is then fed into the positioning box 4 by the feeding slide rail 3. The fruit 5 is pressed against the guide rods 68, causing several guide rods 68 to slide relative to each other on the baffle 43. The guide rods 68 are adapted to the shape of the fruit 5 to be processed. After sliding, the guide rods 68 will slide out of the positioning box 4. At this point, the fruit 5 to be processed is loaded. Then the cutting module 6 is started. The cutting module 6 moves forward along the direction of several positioning boxes 4. When the cutting module 6 moves, the servo motor 65 is started simultaneously, and the servo motor 65 drives the saw blade 66 to rotate. When the cutting module 6 moves, the guide rods 68 will slide and engage with the sliding rods 47 that slide out of the positioning box 4, thereby adapting to the shape of the fruit 5 to be processed and preventing the saw blade 66 from over-cutting and damaging the fruit flesh.

[0040] It is worth noting that although the fruits 5 to be processed are classified by size, there are still size differences between fruits 5 within the same size range. If fruits 5 within the same size range are cut to the same depth, the smaller fruits 5 are easily cut to the flesh, causing damage to the flesh. However, in this embodiment, the hydraulic cylinder 2 applies pressure to the fruits 5 to squeeze the slide rod 47 out of the positioning box 4. Then, the guide rod 68 in the cutting module 6 slides and engages with the slide rod 47 that has slid out of the positioning box 4, so that it can accurately fit each fruit 5 in the positioning box 4. This allows the cutting module 6 to make cuts according to the shape of the fruit 5, avoiding cutting the flesh of the fruit 5, which would damage the flesh after cutting. This achieves automated feeding and positioning. Through the cooperation of the slide rod 47 and the guide rod 68, the cutting depth adapts to the size of the fruit 5, avoiding cutting the flesh, improving cutting accuracy and consistency. The overall structure is compact, supports continuous processing, and improves efficiency.

[0041] In addition, it should be noted that in this embodiment, the slide rods 47 are arranged in an array in the baffle 43. When the fruit to be processed 5 comes into contact with the slide rods 47 and drives the slide rods 47 to slide out of the positioning box 4, the gap between the slide rods 47 is extremely small. The slide rods 47 that slide out of the positioning box 4 can effectively form a track for the guide rods 68 to slide relative to each other. Thus, when the cutting module 6 is displaced, the saw blade 66 can be guided to adapt to the shape of the fruit to be processed 5 to perform the cutting operation.

[0042] The limiting rod 67 is rotatably connected to the output end of the servo motor 65, and the limiting rod 67 is fixed to the mounting plate 64. This ensures that after the servo motor 65 is started, the guide rod 68 always contacts the track vertically downward and generates relative sliding. In addition, a return spring (not shown in the figure) should be provided between the slide rod 47 and the baffle 43 to ensure that the slide rod 47 is reset to exit the processing fruit 5.

[0043] like Figures 1 to 3 , Figure 6 , Figure 8 As shown, the positioning box 4 has an open slot 41 at one end adjacent to the feeding slide rail 3, and an abutment slot 48 at the other end of the positioning box 4. The baffle 43 is fixed to the bottom surface of the abutment slot 48. A fitting block 45 is fixed between two adjacent positioning boxes 4, and a guide mold 46 is fixed on the fitting block 45. A low slot 461 is opened on the top of the guide mold 46, and fitting slots 462 are opened on both sides of the guide mold 46.

[0044] Because the cutting module 6, during displacement, guides the saw blade 66 to perform cutting operations on different fruits 5 to be processed via the limiting rod 67 and the guide rod 68, in order to prevent the saw blade from jumping when cutting fruits 5 in two adjacent positioning boxes 4, in this embodiment, a fitting block 45 is provided between two adjacent positioning boxes 4, and a low groove 461 is provided on the fitting block 45. Before the guide rod 68 slides into the low groove 461 before sliding into the sliding rod 47 that has slid out of the positioning box 4, the guide rod 68 slides in the low groove 461. It should be noted that... The low groove 461 and the sliding rod 47 that slides out of the positioning box 4 transition smoothly. It can be understood that when the cutting module 6 is displaced, the guide rod 68 first slides on the low groove 461 at the top of the mating block 45, and then slides through the low groove 461 to the "track" formed by several sliding rods 47. Due to the arrangement of the low groove 461, the guide rod 68 can smoothly transition from the mating block 45 to the sliding rod 47. In addition, the mating block 45 is also provided with a mating groove 462, which is used to avoid the sliding rod 47 in the positioning box 4.

[0045] Furthermore, when the fruit to be processed 5 is fed into the positioning box 4 from the outlet end of the feeding slide rail 3, the fruit to be processed 5 is located in the open groove 41, and the open groove 41 can restrict the fruit to be processed 5, and as Figure 5As shown, the top of the cross-section of the fruit to be processed 5 should be higher than the highest sliding rod 47, and similarly, the bottom of the cross-section should be lower than the lowest sliding rod 47. Based on this setting, when the guide rod 68 slides in the "track" formed by several sliding rods 47, the saw blade 66 can effectively contact the fruit to be processed 5 and fix the cutting depth. Through the low groove 461 and the mating groove 462, the guide rod 68 can smoothly transition when switching between different positioning boxes 4, preventing the cutting module 6 from jumping, ensuring the continuity and stability of the cut, and reducing vibration and error.

[0046] like Figures 1 to 5 , Figure 7 As shown, the cutting module 6 also includes a tool slide rail 61, in which a slider 63 is slidably connected. A lead screw 62 is threaded into the middle of the slider 63. An oblong groove 631 is formed on the bottom side wall of the slider 63. A support rod 641 is fixedly connected to the top of the mounting plate 64. The support rod 641 passes through the bottom of the slider 63, and a positioning pin is connected through the top of the support rod 641. The positioning pin passes through the oblong groove 631. A third spring 69 is sleeved on the support rod 641. The two ends of the third spring 69 abut against the slider 63 and the mounting plate 64.

[0047] The saw blade 66 and servo motor 65 are fixed by mounting plate 64, and the combination of saw blade 66, servo motor 65 and mounting plate 64 is connected to slider 63 via support rod 641. To improve the efficiency of cutting batches of fruits 5 to be processed, generally speaking, several positioning boxes 4 need to be arranged in an array so that multiple fruits 5 to be processed can be processed after the cutting module 6 completes one displacement. In this embodiment, the lead screw 62 is driven to rotate by an external motor. Based on the threaded engagement between the lead screw 62 and slider 63, slider 63 slides in the tool slide rail 61. When saw blade 66 and servo motor 65 move along the array direction of several positioning boxes 4, they can continuously cut the fruits 5 to be processed in several positioning boxes 4. It is worth noting that since the size of the fruits 5 to be processed may vary, the sliding engagement of the guide rod 68 and several sliding rods 47 forming the "track" is used. Figure 10As shown, the arrows indicate the displacement path of the guide rod 68, and the dashed lines represent the historical trajectory of the guide rod 68. This allows the saw blade 66 and the servo motor 65 to move axially along the guide rod 68 to adapt to the cutting operation of different sized fruits 5. Specifically, when the guide rod 68 drives the mounting plate 64, the servo motor 65, and the saw blade 66 to move upward along the axial direction, the support rod 641 slides into the bottom of the slider 63 and compresses the third spring 69. The third spring 69 ensures that the guide rod 68 always contacts the "track" formed by the mating block 45 and several sliding rods 47. The lead screw 62 drives the precise linear movement of the cutting module 6, and the third spring 69 provides flexible buffering, allowing the saw blade 66 to adapt to changes in the shape of the fruit 5, improving the consistency of the cutting depth and avoiding damage to components from hard collisions.

[0048] like Figures 1 to 10 As shown, a top partition plate 13 is fixedly connected to the middle surface of the base plate 1. The output end of the hydraulic cylinder 2 passes through the top partition plate 13 and the feeding slide rail 3. The output end of the hydraulic cylinder 2 is connected to an abutment part 23 via a spline. A third sliding groove 24 is provided on the abutment part 23. An abutment rod 26 is slidably connected in the abutment part 23. A first spring 25 is fixed between one end of the abutment rod 26 located in the abutment part 23 and the bottom surface of the abutment part 23. When the output end of the hydraulic cylinder 2 outputs, it drives the abutment part 23 to pass through the feeding slide rail 3 and pushes the fruit to be processed 5 carried at the outlet end of the feeding slide rail 3 into the positioning box 4 based on the abutment rod 26, while applying pressure to the fruit to be processed 5.

[0049] The hydraulic cylinder 2 has a second slide groove 21 in the middle. A contact part 22 is slidably connected in the second slide groove 21. The contact part 22 is located between the feed slide rail 3 and the top partition plate 13. When the output end of the hydraulic cylinder 2 outputs, the feed slide rail 3 is driven to slide on the bottom plate 1 through the contact part 22 and the second slide groove 21, so that the outlet end of the feed slide rail 3 is connected to the open groove 41 of the positioning box 4.

[0050] The bottom surface of the open slot 41 of the positioning box 4 is provided with a relief slot 42. The outlet end of the feeding slide rail 3 is hinged with a baffle plate relative to the relief slot 42. When the fruit to be processed 5 slides from the top of the feeding slide rail 3 to the outlet end of the feeding slide rail 3, it is blocked by the baffle plate and temporarily stored at the outlet end of the feeding slide rail 3. When the contact part 23 penetrates the feeding slide rail 3 and applies pressure to the fruit to be processed 5, the fruit to be processed 5 squeezes the baffle plate, causing the baffle plate to embed into the relief slot 42, and the fruit to be processed 5 is pushed into the positioning box 4.

[0051] The feeding slide rail 3 is used to guide the sorted fruits 5 to be processed, so that the fruits 5 are moved into the positioning box 4 via the feeding slide rail 3. In this embodiment, based on the baffle plate set at the outlet end of the feeding slide rail 3, the fruits 5 entering the feeding slide rail 3 can be limited, so that the fruits 5 are temporarily stored at the outlet end of the feeding slide rail 3. Subsequently, when the hydraulic cylinder 2 outputs, the output end drives the abutment part 23 to pass through the feeding slide rail 3 and apply pressure to the fruits 5, so that the fruits 5 are pushed into the positioning box 4 from the outlet end of the feeding slide rail 3. It should be noted that before the abutment part 23 contacts the fruits 5, the abutment part 22 located on the output end of the hydraulic cylinder 2 will be blocked and limited by the second slide groove 21, and the output continues. Then, the abutment part 22 presses the feeding slide rail 3 to slide on the base plate 1, and causes the feeding slide rail 3 to move in the output direction of the hydraulic cylinder 2, so that the outlet end of the feeding slide rail 3 connects with the open groove 41 of the positioning box 4. Then, the output continues, and the abutment part 23 applies pressure to the fruit to be processed 5 and presses the baffle plate, so that the baffle plate rotates and is embedded in the relief groove 42 in the positioning box 4. Then, the output continues, and the abutment part 23 can press the fruit to be processed 5 from the outlet end of the feeding slide rail 3 to the open groove 41 in the positioning box 4, thereby realizing the feeding of the fruit to be processed 5 into the positioning box 4. Based on the cooperation of the hydraulic cylinder 2 and the abutment part 23, the fruit to be processed 5 in the positioning box 4 is limited, so that the fruit to be processed 5 remains in a fixed state during the processing.

[0052] Furthermore, it should be noted that in the initial state, the feeding slide rail 3 and the positioning box 4 are not in contact. That is, when the sorted fruit to be processed 5 enters the feeding slide rail 3, the baffle plate limits the fruit to be processed 5, so that the fruit to be processed 5 is temporarily stored at the outlet end of the feeding slide rail 3. Then, after the hydraulic cylinder 2 outputs, the feeding slide rail 3 is squeezed by the abutment part 22 and moves towards the positioning box 4, so that the outlet end is connected with the open groove 41 and continues to output. Based on the pressure of the abutment part 23 on the fruit to be processed 5, the baffle plate is forced to rotate and embed into the relief groove 42. Under pressure, the fruit to be processed 5 moves from the outlet end of the feeding slide rail 3 into the positioning box 4, completing the feeding. Among them, the abutment part 23 is based on the abutment rod 26 and the fruit to be processed The contact rod 26 and the contact part 23 are directly connected by the first spring 25. Therefore, the compression of the fruit 5 to be processed is not directly applied, thus avoiding excessive output of the hydraulic cylinder 2 and direct breakage of the fruit 5. The spline connection improves the transmission stability, and the first spring 25 buffers the pressure to prevent the fruit 5 from being crushed, achieving gentle and reliable feeding and fixing, improving processing safety. Based on the hydraulic cylinder 2, the contact part 22 and the contact part 23, the automatic docking of the feeding slide rail 3 is realized, ensuring the smooth transfer of the fruit 5 to be processed, reducing manual intervention, improving feeding efficiency and positioning accuracy. The baffle plate acts as a one-way valve to ensure orderly feeding of the fruit 5 to be processed, avoiding blockage or repeated feeding, and improving process reliability.

[0053] like Figures 1 to 4 , Figure 6 As shown, the base plate 1 has an open slot 41 adjacent to the positioning box 4 with a discharge port 15 and a first slide groove 16. The discharge port 15 is connected to the first slide groove 16. The bottom of the feeding slide rail 3 is fixedly connected to a connecting plate, and the connecting plate is slidably connected in the first slide groove 16. When the processing of the fruit 5 is completed, the output end of the hydraulic cylinder 2 retracts, the feeding slide rail 3 retracts, and the guide rod 68 drives the fruit 5 to exit from the open slot 41 of the positioning box 4 and be discharged through the discharge port 15.

[0054] Based on the above, the processing of the fruit to be processed 5 includes: after sorting, it enters the feeding slide rail 3, and then is output by the hydraulic cylinder 2. The hydraulic cylinder 2, in conjunction with the contact part 22, drives the feeding slide rail 3 to slide and connect to the positioning box 4. Then, based on the contact part 23 passing through the feeding slide rail 3 to contact the fruit to be processed 5, the fruit to be processed 5 is driven to overcome the obstruction plate and enter the positioning box 4. After the fruit to be processed 5 is limited, the cutting module 6 moves along the array direction of the multiple positioning boxes 4, thereby performing a cutting operation on the fruit to be processed 5. When the fruit to be processed 5 is finished being processed, the hydraulic cylinder 2 retracts. The contact part 23 and the abutting part 22 separate from the fruit to be processed 5 and the feeding slide rail 3 in sequence. At this time, the feeding slide rail 3 retracts under no force, exposing the discharge port 15 on the bottom plate 1. It can be understood that when the feeding slide rail 3 retracts, the discharge port 15 located between the positioning box 4 and the feeding slide rail 3 is fully exposed. At this time, the baffle plate is reset under the action of the torsion spring (the torsion spring is installed at the connection between the baffle plate and the feeding slide rail 3 to drive the baffle plate to reset under no external force). At this time, since one side of the fruit to be processed 5 is no longer subjected to resistance... Due to the compression of the contact 23, the slide bar 47 will elastically compress the processed fruit 5 and eject it from the positioning box 4. Under the limiting action of the baffle plate, the processed fruit 5 will eject from the positioning box 4 and be discharged through the discharge port 15. A return spring is provided between the slide bar 47 and the baffle plate 43. When the processed fruit 5 compresses the slide bar 47, the return spring stretches to generate elastic potential energy. When the processed fruit 5 no longer applies pressure to the slide bar 47, the slide bar 47 can eject the processed fruit 5 under the action of the return spring. Based on this, in this embodiment... The contact part 23 drives the fruit to be processed 5 into the positioning box 4, and the continuous pressure applied fixes the fruit to be processed 5 in the positioning box 4. The fruit to be processed 5 indirectly applies pressure to the slide rod 47, causing the slide rod 47 to slide relative to the baffle 43. When the contact part 23 retracts, the return spring and the slide rod 47 drive the fruit to be processed 5 out of the positioning box 4, and provide the power to transfer the fruit to be processed 5 from the positioning box 4 to the discharge port 15, thus realizing the continuous action of feeding the fruit to be processed 5 and automatically discharging it after processing.

[0055] like Figures 1 to 4As shown, a bottom partition plate 14 is fixedly connected to the bottom surface of the middle part of the bottom plate 1, and a connecting rod 32 is fixedly connected to the connecting plate, and the connecting rod 32 passes through the bottom partition plate 14. A second spring 33 is sleeved on the connecting rod 32. The second spring 33 is used to drive the feeding slide rail 3 to retract under the condition of no external force, exposing the discharge port 15 on the bottom plate 1.

[0056] As described above, the feeding slide rail 3, based on the connecting plate, connecting rod 32, and second spring 33, allows the feeding slide rail 3 to initially separate from the positioning box 4, exposing the discharge port 15. When the abutment part 22 drives the feeding slide rail 3 to move, the outlet end of the feeding slide rail 3 contacts the positioning box 4. At this time, the connecting rod is slidably connected to the first slide groove 16, and the second spring 33 is compressed. The two ends of the second spring 33 abut against the bottom partition plate 14 and the end of the connecting rod 32, respectively. It is worth noting that a plug is threaded onto the end of the connecting rod 32, and the two ends of the second spring 33 abut against the bottom partition plate 14 and the plug, respectively. Figure 4 As shown; the second spring 33 provides an automatic reset force to ensure that the feed slide rail 3 returns to its original position in time, exposing the discharge port 15 for material discharge and enhancing the degree of automation.

[0057] like Figures 1 to 4 As shown, the bottom surface of the base plate 1 is fixedly connected to the feeding port 15 with a feeding hopper 12, which is used to guide the fruit 5 to be processed discharged through the feeding port 15. The surface of the base plate 1 is fixedly connected to a fixing frame 11, and the tool slide rail 61 is fixedly connected to the bottom of the fixing frame 11. The feeding hopper 12 guides the collection of processed fruit, and the fixing frame 11 enhances the stability of the cutting module 6 and improves the overall rigidity and reliability.

[0058] like Figures 1 to 5 , Figure 7 As shown, a counterweight is fixed to the top of the guide rod 68 to drive the guide rod 68 to always smoothly contact the low groove 461; the counterweight keeps the guide rod 68 in close contact with the "track", reducing vibration and jumping, and ensuring the cutting accuracy and consistency.

[0059] Working principle: After being sorted by size, the fruit to be processed 5 is fed into the feeding slide rail 3 by an external sorting device. Once inside the feeding slide rail 3, the fruit 5 slides from the top to the outlet end, and is then fed into the positioning box 4 from the outlet end. Subsequently, the hydraulic cylinder 2 outputs its power, with the output end of the hydraulic cylinder 2 abutting against the side wall of the fruit 5 inside the positioning box 4. This ensures that both sides of the fruit 5 are fixed between the inner side wall of the positioning box 4 and the output end of the hydraulic cylinder 2, thus fixing the fruit 5 inside the positioning box 4 and ensuring its stability during the cutting process. When the fruit 5 is inside the positioning box 4, it... The guide rods 68 are squeezed, causing them to slide relative to each other on the baffle 43. The guide rods 68 are adapted to the shape of the fruit 5 to be processed. After sliding, the guide rods 68 will slide out of the positioning box 4. At this point, the fruit 5 to be processed is loaded. Then the cutting module 6 is started. The cutting module 6 moves forward along the direction of the positioning boxes 4. When the cutting module 6 moves, the servo motor 65 is started simultaneously, which drives the saw blade 66 to rotate. When the cutting module 6 moves, the guide rods 68 will slide and engage with the sliding rods 47 that slide out of the positioning box 4, thereby adapting to the shape of the fruit 5 to be processed and preventing the saw blade 66 from over-cutting and damaging the fruit flesh.

[0060] It is worth noting that although the fruits 5 to be processed are classified by size, there are still size differences between fruits 5 within the same size range. If fruits 5 within the same size range are cut to the same depth, the smaller fruits 5 are easily cut to the flesh, causing damage to the flesh. However, in this embodiment, the hydraulic cylinder 2 applies pressure to the fruits 5 to squeeze the slide rod 47 out of the positioning box 4. Then, the guide rod 68 in the cutting module 6 slides and engages with the slide rod 47 that has slid out of the positioning box 4, so that it can accurately fit each fruit 5 in the positioning box 4. This allows the cutting module 6 to make cuts according to the shape of the fruit 5, avoiding cutting the flesh of the fruit 5, which would damage the flesh after cutting. This achieves automated feeding and positioning. Through the cooperation of the slide rod 47 and the guide rod 68, the cutting depth adapts to the size of the fruit 5, avoiding cutting the flesh, improving cutting accuracy and consistency. The overall structure is compact, supports continuous processing, and improves efficiency.

[0061] A fitting block 45 is provided between two adjacent positioning boxes 4, and a low groove 461 is provided on the fitting block 45. Before the guide rod 68 slides into the sliding rod 47 that slides out of the positioning box 4, the guide rod 68 slides in the low groove 461. It should be noted that the low groove 461 and the sliding rod 47 that slide out of the positioning box 4 transition smoothly. It can be understood that when the cutting module 6 is displaced, the guide rod 68 first slides in the low groove 461 at the top of the fitting block 45, and then slides through the low groove 461 to the "track" formed by several sliding rods 47. Due to the arrangement of the low groove 461, the guide rod 68 can smoothly transition from the fitting block 45 to the sliding rod 47. In addition, a fitting groove 462 is also provided on the fitting block 45. The fitting groove 462 is used to avoid the sliding rod 47 inside the positioning box 4.

[0062] Furthermore, when the fruit to be processed 5 is fed into the positioning box 4 from the outlet end of the feeding slide rail 3, the fruit to be processed 5 is located in the open groove 41, and the open groove 41 can restrict the fruit to be processed 5, and as Figure 5 As shown, the top of the cross-section of the fruit to be processed 5 should be higher than the highest sliding rod 47, and similarly, the bottom of the cross-section should be lower than the lowest sliding rod 47. Based on this setting, when the guide rod 68 slides in the "track" formed by several sliding rods 47, the saw blade 66 can effectively contact the fruit to be processed 5 and fix the cutting depth. Through the low groove 461 and the mating groove 462, the guide rod 68 can smoothly transition when switching between different positioning boxes 4, preventing the cutting module 6 from jumping, ensuring the continuity and stability of the cut, and reducing vibration and error.

[0063] An external motor drives the lead screw 62 to rotate. Based on the threaded engagement between the lead screw 62 and the slider 63, the slider 63 slides within the tool guide rail 61. When the saw blade 66 and the servo motor 65 move along the array direction of several positioning boxes 4, they can continuously cut the fruit 5 to be processed in several positioning boxes 4. It is worth noting that since the size of the fruit 5 to be processed may vary, the sliding engagement of the guide rod 68 and several sliding rods 47 forms a "track," allowing the saw blade 66 and the servo motor 65 to move axially along the guide rod 68 to accommodate the different sizes of the fruit 5. For cutting different sized fruits 5, specifically, when the guide rod 68 drives the mounting plate 64, servo motor 65, and saw blade 66 to move upward along the axial direction, the support rod 641 slides into the bottom of the slider 63 and compresses the third spring 69. The third spring 69 ensures that the guide rod 68 always contacts the "track" formed by the mating block 45 and several sliding rods 47. The lead screw 62 drives the precise linear movement of the cutting module 6, and the third spring 69 provides flexible buffering, allowing the saw blade 66 to adapt to changes in the shape of the fruit 5, improving the consistency of the cutting depth and avoiding damage to components from hard collisions.

[0064] Based on the baffle plate installed at the outlet end of the feeding slide rail 3, the fruit to be processed 5 entering the feeding slide rail 3 can be limited, so that the fruit to be processed 5 is temporarily stored at the outlet end of the feeding slide rail 3. Subsequently, when the hydraulic cylinder 2 outputs, the output end drives the contact part 23 to pass through the feeding slide rail 3 and apply pressure to the fruit to be processed 5, so that the fruit to be processed 5 is pushed from the outlet end of the feeding slide rail 3 into the positioning box 4. It should be noted that before the contact part 23 contacts the fruit to be processed 5, the abutment part 22 located on the output end of the hydraulic cylinder 2 will be blocked by the second slide groove 21 and limited. After the output continues, the abutment part 22 squeezes the feeding slide rail 3 to slide on the base plate 1, and makes it... The feeding slide rail 3 moves along the output direction of the hydraulic cylinder 2, so that the outlet end of the feeding slide rail 3 connects with the open groove 41 of the positioning box 4. Then, the output continues, and the contact part 23 applies pressure to the fruit to be processed 5 and squeezes the baffle plate, so that the baffle plate rotates and is embedded in the relief groove 42 in the positioning box 4. Then, the output continues, and the contact part 23 can squeeze the fruit to be processed 5 from the outlet end of the feeding slide rail 3 to the open groove 41 in the positioning box 4, thereby realizing the feeding of the fruit to be processed 5 into the positioning box 4. Based on the cooperation of the hydraulic cylinder 2 and the contact part 23, the fruit to be processed 5 in the positioning box 4 is limited, so that the fruit to be processed 5 remains in a fixed state during the processing.

[0065] Furthermore, it should be noted that in the initial state, the feeding slide rail 3 and the positioning box 4 are not in contact. That is, when the sorted fruit to be processed 5 enters the feeding slide rail 3, the baffle plate limits the fruit to be processed 5, so that the fruit to be processed 5 is temporarily stored at the outlet end of the feeding slide rail 3. Then, after the hydraulic cylinder 2 outputs, the feeding slide rail 3 is squeezed by the abutment part 22 and moves towards the positioning box 4, so that the outlet end is connected with the open groove 41 and continues to output. Based on the pressure of the abutment part 23 on the fruit to be processed 5, the baffle plate is forced to rotate and embed into the relief groove 42. Under pressure, the fruit to be processed 5 moves from the outlet end of the feeding slide rail 3 into the positioning box 4, completing the feeding. Among them, the abutment part 23 is based on the abutment rod 26 and the fruit to be processed The contact rod 26 and the contact part 23 are directly connected by the first spring 25. Therefore, the compression of the fruit 5 to be processed is not directly applied, thus avoiding excessive output of the hydraulic cylinder 2 and direct breakage of the fruit 5. The spline connection improves the transmission stability, and the first spring 25 buffers the pressure to prevent the fruit 5 from being crushed, achieving gentle and reliable feeding and fixing, improving processing safety. Based on the hydraulic cylinder 2, the contact part 22 and the contact part 23, the automatic docking of the feeding slide rail 3 is realized, ensuring the smooth transfer of the fruit 5 to be processed, reducing manual intervention, improving feeding efficiency and positioning accuracy. The baffle plate acts as a one-way valve to ensure orderly feeding of the fruit 5 to be processed, avoiding blockage or repeated feeding, and improving process reliability.
