Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of fruit shell cutting, and in particular to an automatic cutting device for macadamia nut processing. BACKGROUND

[0002] As a high-value nut, macadamia nuts need to have slots cut in their hard shells during processing to facilitate the penetration of flavorings and consumption by consumers. In the prior art, macadamia nut cutting devices are mostly focused on simple cutting mechanisms, but often have low automation, insufficient cutting precision, and low efficiency, leading to unstable processing quality and resource waste.

[0003] In the prior art, a typical macadamia nut opening device, such as the one disclosed in CN107752820B, uses a double-layer cutting blade design to avoid the problem of the fruit being cut in half, thereby improving the eating experience. The device includes a rack, a cutting assembly, and a guide seat: However, this device still has obvious defects. First, its feeding and positioning rely on manual operation, and the lower plate pushes the fruit in the fruit container groove through the cylinder, but lacks a continuous automatic feeding system, resulting in low processing efficiency and difficulty in meeting large-scale production needs. Second, the movement control of the cutting assembly is complex, and the cutting assembly relies on a lead screw, a profiling wheel, and a spring to adjust the cutting depth, but this design is easily affected by variations in fruit size, resulting in inconsistent cutting depth and even damage to the kernel. In addition, the existing device does not have a stable fruit fixation, and the bottom of the fruit container groove is provided with friction lines, but the fruit is prone to sliding during high-speed cutting, affecting the cutting precision. Although the cooperation between the profiling wheel and the profiling base is demonstrated, the vibration problem during fruit positioning is not solved. More importantly, the existing technology mainly focuses on the number of slots (double-layer cutting) to avoid being cut in half, but ignores the overall automation process, such as the continuity of feeding, positioning, and discharging, which limits production efficiency and reliability.

[0004] In summary, the existing macadamia nut cutting device has significant deficiencies in automation, precision, and efficiency, and there is an urgent need for a solution that integrates automatic feeding, precise positioning, and efficient cutting.

[0019] 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.

[0020] 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. 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. 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.

[0021] In the prior art, the feeding and positioning rely on manual operation, the down plate pushes the fruit in the fruit containing groove through the cylinder, but there is no continuous automatic feeding system, which leads to low processing efficiency and is difficult to adapt to large-scale production demand; secondly, the motion control of the cutting assembly is relatively complex, the cutting assembly relies on the screw, the profiling wheel and the spring to realize the cutting depth adjustment, but such design is easily affected by the size variation of the fruit, leading to inconsistent incision depth and even damage to the fruit kernel; in addition, the existing device is not stable in fixing the fruit, although the friction lines are arranged on the bottom surface of the fruit containing groove, the fruit is easy to slide in the high-speed cutting process, which affects the incision accuracy, although the cooperation between the profiling wheel and the profiling base body is shown, the vibration problem during the fruit positioning is not solved; more importantly, the existing technology mainly focuses on the number of notches (double-layer cutting) to avoid halving, but ignores the overall automatic process, such as the continuity of feeding, positioning and discharging, which limits the production efficiency and reliability.

[0022] In one embodiment of the present application, after the fruit 5 to be processed is classified in size, it is discharged into the feeding slide rail 3 by the external classification device. The fruit 5 to be processed in the feeding slide rail 3 will slide from the top to the outlet end of the feeding slide rail 3, and then the fruit 5 to be processed will be sent into the positioning box body 4 from the outlet end of the feeding slide rail 3. Then the hydraulic cylinder 2 outputs, and the output end of the hydraulic cylinder 2 abuts against the side wall of the fruit 5 to be processed in the positioning box body 4, so that the two sides of the fruit 5 to be processed are respectively abutted between the inner side wall of the positioning box body 4 and the output end of the hydraulic cylinder 2, so that the fruit 5 to be processed is fixed after entering the positioning box body 4, thereby ensuring the stability of the fruit 5 to be processed during the incision process. When the fruit 5 to be processed abuts against the inside of the positioning box body 4, the guide rods 68 are extruded by the fruit 5 to be processed, so that the guide rods 68 slide on the baffle 43, and the guide rods 68 are adapted to the shape of the fruit 5 to be processed. After the guide rods 68 slide, they slide out of the positioning box body 4. At this time, the loading of the fruit 5 to be processed is completed, and then the incision module 6 is started. The displacement direction of the incision module 6 is forward along the direction of the positioning box body 4, and the servo motor 65 is started synchronously when the incision module 6 is displaced. The saw blade 66 is driven to rotate by the servo motor 65. When the incision module 6 is displaced, the guide rods 68 therein slide with the slide rods 47 that slide out of the positioning box body 4, so as to adapt to the shape of the fruit 5 to be processed, thereby preventing the saw blade 66 from cutting excessively and damaging the fruit flesh; 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.

[0023] 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. 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.

[0024] 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.

[0025] As the cutting module 6 is displaced, the saw blade 66 is guided by the limiting rod 67 and the guide rod 68 to perform cutting operations on different fruits 5 to be processed, in order to prevent the occurrence of knife jumping when cutting the fruits 5 to be processed in the adjacent two positioning box bodies 4, in the embodiment, a fitting block 45 is arranged between the adjacent two positioning box bodies 4, and a low-position slot 461 is arranged on the fitting block 45, and before the guide rod 68 is in sliding cooperation with the slide rod 47 of the slide-out positioning box body 4, the guide rod 68 slides in the low-position slot 461, and it should be noted that the low-position slot 461 is smoothly transitioned with the slide rod 47 of the slide-out positioning box body 4, and it can be understood that when the cutting module 6 is displaced, the guide rod 68 first slides in the low-position slot 461 on the top of the fitting block 45, and then slides on the "track" formed by the plurality of slide rods 47 through the low-position slot 461, and due to the arrangement of the low-position slot 461, the guide rod 68 can be smoothly transitioned from the fitting block 45 to the slide rod 47, in addition, the fitting block 45 is also provided with a fitting slot 462, and the fitting slot 462 is used to avoid the slide rod 47 in the positioning box body 4; In addition, when the fruit 5 to be processed is sent into the positioning box body 4 from the outlet end of the feeding slide rail 3, the fruit 5 to be processed is in the open slot 41, and the open slot 41 can limit the fruit 5 to be processed, and as shown in Figure 5 The cross-section top of the fruit 5 to be processed is higher than the highest slide rod 47, and the cross-section bottom is lower than the lowest slide rod 47, based on this setting, when the guide rod 68 is in sliding cooperation with the "track" formed by the plurality of slide rods 47, the saw blade 66 can effectively contact the fruit 5 to be processed and fix the cutting depth, through the low-position slot 461 and the fitting slot 462, the guide rod 68 is smoothly transitioned when switching between different positioning box bodies 4, preventing the cutting module 6 from jumping, ensuring the continuity and stability of the cutting, and reducing vibration and error.

[0026] As shown in Figures 1 to 5 , Figure 7 The cutting module 6 also includes a tool slide rail 61, a sliding block 63 is slidably connected in the tool slide rail 61, a lead screw 62 is threadedly connected in the middle of the sliding block 63, a waist round groove 631 is formed in the bottom side wall of the sliding block 63, a support rod 641 is fixedly connected to the top of the mounting plate 64, the support rod 641 penetrates the bottom of the sliding block 63, and a positioning pin is connected at the top of the support rod 641, the positioning pin penetrates the waist round groove 631, and a third spring 69 is sleeved on the support rod 641, and the two ends of the third spring 69 abut between the sliding block 63 and the mounting plate 64.

[0027] The saw blade 66 and the servo motor 65 are fixed through the mounting plate 64, and the combination of the saw blade 66, the servo motor 65 and the mounting plate 64 is connected with the sliding block 63 through the supporting rod 641. In order to improve the cutting efficiency of the batch of to-be-processed fruits 5, generally, a plurality of positioning boxes 4 need to be arranged in an array, so that a plurality of to-be-processed fruits 5 can be processed after one complete displacement of the cutting module 6. In the embodiment, the external motor drives the screw rod 62 to rotate, and based on the threaded cooperation between the screw rod 62 and the sliding block 63, the sliding block 63 slides in the cutter sliding rail 61. When the saw blade 66 and the servo motor 65 displace along the array direction of the plurality of positioning boxes 4, the to-be-processed fruits 5 in the plurality of positioning boxes 4 can be continuously cut. It is worth noting that, as the size of the to-be-processed fruits 5 may be different, based on the sliding cooperation of the guide rod 68 and the “track” formed by the plurality of sliding rods 47, as shown in Figure 10 the arrow is the displacement path of the guide rod 68, and the dotted line is the historical track of the guide rod 68. The saw blade 66 and the servo motor 65 can displace along the guide rod 68 in the axial direction to adapt to the cutting operation of to-be-processed fruits 5 of different sizes. Specifically, when the guide rod 68 drives the mounting plate 64, the servo motor 65 and the saw blade 66 to move upward in the axial direction, the supporting rod 641 will slide into the bottom of the sliding block 63 and press the third spring 69. Based on the third spring 69, it can be ensured that the guide rod 68 always contacts the “track” formed by the engagement block 45 and the plurality of sliding rods 47. The screw rod 62 drives the precise linear movement of the cutting module 6, and the third spring 69 provides flexible buffering, so that the saw blade 66 can adapt to the shape change of the to-be-processed fruits 5, improve the consistency of the cutting depth, and avoid hard collision and damage to the components.

[0028] As shown in Figures 1 to 10 the middle surface of the bottom plate 1 is fixedly connected with a top partition plate 13, the output end of the hydraulic oil cylinder 2 penetrates the top partition plate 13 and the feeding sliding rail 3, the output end of the hydraulic oil cylinder 2 is connected with a resisting part 23 through a spline, the resisting part 23 is provided with a third sliding groove 24, and the resisting part 23 is slidably connected with a resisting rod 26. One end of the resisting rod 26 located in the resisting part 23 is fixedly connected with a first spring 25 between the bottom surface of the resisting part 23. When the output end of the hydraulic oil cylinder 2 outputs, the resisting part 23 penetrates the feeding sliding rail 3, and based on the resisting rod 26, the to-be-processed fruits 5 carried by the outlet end of the feeding sliding rail 3 are pushed into the positioning box 4, and the to-be-processed fruits 5 are subjected to pressure.

[0029] The middle part of the hydraulic oil cylinder 2 is provided with a second sliding groove 21, and the second sliding groove 21 is slidably connected with an abutting part 22. The abutting part 22 is located between the feeding sliding rail 3 and the top partition plate 13. When the output end of the hydraulic oil cylinder 2 outputs, the abutting part 22 is abutted with the second sliding groove 21 to drive the feeding sliding rail 3 to slide on the bottom plate 1, so that the outlet end of the feeding sliding rail 3 is connected with the open slot 41 of the positioning box 4.

[0030] The bottom surface of the open slot 41 of the positioning box 4 is provided with a let-in slot 42, and the outlet end of the feeding slide rail 3 is hinged with a blocking plate relative to the let-in 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, the fruit to be processed 5 is temporarily stored at the outlet end of the feeding slide rail 3 by being blocked by the blocking plate. When the abutting part 23 penetrates the feeding slide rail 3 and exerts pressure on the fruit to be processed 5, the fruit to be processed 5 extrudes the blocking plate, so that the blocking plate is embedded in the let-in slot 42, and the fruit to be processed 5 is pushed into the positioning box 4.

[0031] The feeding slide rail 3 is used to guide the classified fruit to be processed 5 to move into the positioning box 4 through the feeding slide rail 3. In this embodiment, based on the blocking plate arranged 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. Then, when the hydraulic cylinder 2 outputs, the output end drives the abutting part 23 to penetrate the feeding slide rail 3 and exert pressure on the fruit to be processed 5, so that the fruit to be processed 5 is pushed into the positioning box 4 from the outlet end of the feeding slide rail 3. It should be noted that before the abutting part 23 contacts the fruit to be processed 5, the abutting part 22 on the output end of the hydraulic cylinder 2 is limited by the second sliding groove 21. After continuous output, the abutting part 22 extrudes the feeding slide rail 3 to slide on the bottom plate 1, and makes the feeding slide rail 3 displace along the output direction of the hydraulic cylinder 2, so that the outlet end of the feeding slide rail 3 is connected with the open slot 41 of the positioning box 4. Then, the abutting part 23 continues to output and exerts pressure on the fruit to be processed 5, and extrudes the blocking plate, so that the blocking plate rotates and is embedded in the let-in slot 42 in the positioning box 4. Then, the abutting part 23 continues to output and can extrude the fruit to be processed 5 to be transferred from the outlet end of the feeding slide rail 3 to the open slot 41 in the positioning box 4, so as to realize 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 abutting 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 processing; Further, it is noted that in the initial state, the feeding slide rail 3 is not in contact with the positioning box body 4, that is, when the classified fruit to be processed 5 enters the feeding slide rail 3, the fruit to be processed 5 is limited by the blocking plate, and the fruit to be processed 5 is temporarily stored at the outlet end of the feeding slide rail 3. Subsequently, after the output of the hydraulic oil cylinder 2, the feeding slide rail 3 is extruded by the abutting portion 22 and is displaced towards the positioning box body 4, so that the outlet end is connected with the open slot 41, and the output continues. Based on the extrusion of the fruit to be processed 5 by the abutting portion 23, the blocking plate is rotated and embedded in the accommodation groove 42, and under pressure, the fruit to be processed 5 is moved from the outlet end of the feeding slide rail 3 to the positioning box body 4, and the feeding is completed. The abutting portion 23 is in direct contact with the fruit to be processed 5 based on the abutting rod 26, and the abutting rod 26 and the abutting portion 23 are connected by the first spring 25. Therefore, the extrusion of the fruit to be processed 5 is not directly pressed, so that the fruit to be processed 5 is not directly broken due to excessive output of the hydraulic oil cylinder 2. The spline connection improves the transmission stability, and the first spring 25 buffers the pressure to prevent the fruit to be processed 5 from being crushed, realizes soft and reliable feeding and fixing, improves the processing safety, and based on the hydraulic oil cylinder 2, the abutting portion 22 and the abutting portion 23, realizes the automatic docking of the feeding slide rail 3, ensures the smooth transfer of the fruit to be processed 5, reduces the manual intervention, improves the feeding efficiency and positioning accuracy, the blocking plate as a one-way valve ensures the orderly feeding of the fruit to be processed 5, avoids the blockage or repeated feeding, and improves the process reliability.

[0032] As shown in Figures 1 to 4 , Figure 6 , the bottom plate 1 is provided with a discharge port 15 and a first sliding groove 16 adjacent to the open slot 41 of the positioning box body 4, and the discharge port 15 is in communication with the first sliding groove 16. The bottom of the feeding slide rail 3 is fixedly connected with a connecting plate, and the connecting plate is slidingly connected in the first sliding groove 16. When the fruit to be processed 5 is processed, the output end of the hydraulic oil cylinder 2 is retracted, the feeding slide rail 3 is retracted, the guide rod 68 drives the fruit to be processed 5 to exit the open slot 41 of the positioning box body 4, and the fruit to be processed 5 is discharged through the discharge port 15.

[0033] Based on the above, the processing process of the to-be-processed fruit 5 includes: after classification, entering the feeding slide rail 3, then output by the hydraulic oil cylinder 2, cooperating with the abutting portion 22 to drive the feeding slide rail 3 to slide to connect and position the box body 4, and then based on the abutting portion 23 penetrating through the feeding slide rail 3 to contact the to-be-processed fruit 5, driving the to-be-processed fruit 5 to overcome the blocking plate and enter the positioning box body 4, after the to-be-processed fruit 5 is limited, the cutting module 6 is displaced along the array direction of the plurality of positioning box bodies 4, so as to cut the to-be-processed fruit 5; wherein, when the to-be-processed fruit 5 is processed, the hydraulic oil cylinder 2 is retracted, the abutting portion 23 and the abutting portion 22 are separated from the to-be-processed fruit 5 and the feeding slide rail 3 in turn, at this time, the feeding slide rail 3 is retracted under the condition of not being forced, so that the discharge port 15 on the bottom plate 1 is exposed, wherein it can be understood that when the feeding slide rail 3 is retracted, the discharge port 15 between the positioning box body 4 and the feeding slide rail 3 is completely exposed, and at this time, the blocking plate is reset under the action of the torsional spring (the torsional spring is installed at the connection between the blocking plate and the feeding slide rail 3, and is used to drive the blocking plate to reset under the action of no external force), at this time, since one side of the to-be-processed fruit 5 is no longer extruded by the abutting portion 23, therefore, the slide rod 47 will reversely pop out of the positioning box body 4 based on the elastic extrusion of the to-be-processed fruit 5, and under the limiting action of the blocking plate, the to-be-processed fruit 5 after processing will pop out of the positioning box body 4 and be discharged through the discharge port 15, wherein the reset spring is arranged between the slide rod 47 and the baffle 43, when the to-be-processed fruit 5 extrudes the slide rod 47, the reset spring is stretched to generate elastic potential energy, when the to-be-processed fruit 5 no longer presses the slide rod 47, the slide rod 47 can pop out the to-be-processed fruit 5 under the action of the reset spring, based on this, in the embodiment, the abutting portion 23 is used to drive the to-be-processed fruit 5 to enter the positioning box body 4, and based on the continuous pressure, the to-be-processed fruit 5 is fixed in the positioning box body 4, and based on the to-be-processed fruit 5 indirectly applying pressure to the slide rod 47, the plurality of slide rods 47 and the baffle 43 are relatively slid, when the abutting portion 23 is retracted, the reset spring and the slide rod 47 drive the to-be-processed fruit 5 to exit from the positioning box body 4, and provide power to drive the to-be-processed fruit 5 to transfer from the positioning box body 4 to the discharge port 15, realize the coherent action of the feeding and processing of the to-be-processed fruit 5 and the automatic discharge after processing.

[0034] As Figures 1 to 4 shown, the middle bottom surface of the bottom plate 1 is fixedly connected with a bottom partition plate 14, the connecting plate is fixedly connected with a connecting rod 32, and the connecting rod 32 penetrates through the bottom partition plate 14, the connecting rod 32 is sleeved with a second spring 33, and the second spring 33 is used to drive the feeding slide rail 3 to retract under the condition of no external force, so as to expose the discharge port 15 on the bottom plate 1.

[0035] As described above, the feeding slide rail 3 is based on the connecting plate, the connecting rod 32 and the second spring 33, so that the feeding slide rail 3 is separated from the positioning box body 4 and exposes the discharging port 15 in the initial state, and when the abutting portion 22 drives the feeding slide rail 3 to displace, the outlet end of the feeding slide rail 3 contacts the positioning box body 4, at this time, the connecting rod is slidingly connected in the first sliding groove 16, and the second spring 33 is compressed, wherein the two ends of the second spring 33 are respectively abutted between the bottom partition plate 14 and the end of the connecting rod 32, and it is worth noting that the end of the connecting rod 32 is threadedly connected with a plug, and the two ends of the second spring 33 are respectively abutted between the bottom partition plate 14 and the plug, as shown in Figure 4 ; based on the second spring 33, an automatic reset force is provided to ensure that the feeding slide rail 3 is timely returned to expose the discharging port 15 for discharging, and the degree of automation is enhanced.

[0036] As shown in Figures 1 to 4 , the bottom surface of the bottom plate 1 is fixedly connected with a discharging hopper 12 corresponding to the discharging port 15, which is used to guide the to-be-processed fruit 5 discharged through the discharging port 15, and the surface of the bottom plate 1 is fixedly connected with a fixing frame 11, and the cutter slide rail 61 is fixedly connected at the bottom of the fixing frame 11; the discharging hopper 12 guides the collection of processed fruits, and the fixing frame 11 enhances the stability of the cutting module 6 and improves the overall rigidity and reliability.

[0037] As shown in Figures 1 to 5 , Figure 7 , the top of the guide rod 68 is fixedly connected with a counterweight, which is used to drive the guide rod 68 to always smoothly contact the low-positioned groove 461; the counterweight makes the guide rod 68 always closely contact the “track”, reduces vibration and jumping, and guarantees the cutting accuracy and consistency.

[0038] Working principle: after the classification of the processed fruit 5, the processed fruit 5 is unloaded from the external classification equipment to the feeding slide rail 3. The processed fruit 5 in the feeding slide rail 3 slides from the top to the outlet end of the feeding slide rail 3, and then the processed fruit 5 is sent into the positioning box body 4 from the outlet end of the feeding slide rail 3. Then the hydraulic cylinder 2 outputs, and the output end of the hydraulic cylinder 2 abuts against the side wall of the processed fruit 5 in the positioning box body 4, so that the two sides of the processed fruit 5 abut between the inner wall of the positioning box body 4 and the output end of the hydraulic cylinder 2, so that the processed fruit 5 is fixed in the positioning box body 4, thereby ensuring the stability of the processed fruit 5 during the cutting process. When the processed fruit 5 abuts against the inside of the positioning box body 4, the guide rod 68 is extruded by the processed fruit 5, so that the guide rod 68 slides on the baffle 43, and the guide rod 68 is matched with the shape of the processed fruit 5. After the guide rod 68 slides, it slides out of the positioning box body 4. At this time, the loading of the processed fruit 5 is completed, and then the cutting module 6 is started. The displacement direction of the cutting module 6 is forward along the direction of the positioning box body 4. When the cutting module 6 moves, the servo motor 65 is started synchronously, and the saw blade 66 is driven to rotate by the servo motor 65. When the cutting module 6 moves, the guide rod 68 in the cutting module 6 slides with the slide rod 47 that slides out of the positioning box body 4, so as to adapt to the shape of the processed fruit 5, so as to prevent the saw blade 66 from cutting too much and damaging the fruit flesh; It is worth noting that although there are still size differences between the processed fruit 5 in the same size range after classification, if the same size range of the processed fruit 5 is cut to the same depth, the relatively small size of the processed fruit 5 is easy to be cut to the fruit flesh, causing damage to the fruit flesh. However, in this embodiment, the hydraulic cylinder 2 applies pressure to the processed fruit 5, so that the processed fruit 5 extrudes the slide rod 47 to slide out of the positioning box body 4, and then the guide rod 68 in the cutting module 6 slides with the slide rod 47 that slides out of the positioning box body 4, so as to accurately adapt to the processed fruit 5 in each positioning box body 4, so that the cutting module 6 can adapt to the cutting according to the shape of the processed fruit 5, so as to avoid cutting the fruit flesh of the processed fruit 5, thereby avoiding the damage of the fruit flesh after cutting, realizing automatic feeding and positioning, and improving the cutting precision and consistency. The overall structure is compact, supports continuous processing, and improves the efficiency.

[0039] A fitting block 45 is arranged between two adjacent positioning boxes 4, and a low-position slot 461 is arranged on the fitting block 45. When the guide rod 68 is slidingly matched with the slide rod 47 of the slide-out positioning box 4, the guide rod 68 slides in the low-position slot 461. It should be noted that the low-position slot 461 is smoothly transitioned with the slide rod 47 of the slide-out positioning box 4. It can be understood that when the notch module 6 is displaced, the guide rod 68 first slides in the low-position slot 461 on the top of the fitting block 45, and then slides to the “track” formed by the plurality of slide rods 47 through the low-position slot 461. Due to the arrangement of the low-position slot 461, the guide rod 68 can be smoothly transitioned from the fitting block 45 to the “track” formed by the plurality of slide rods 47. In addition, a fitting slot 462 is also arranged on the fitting block 45, which is used to avoid the slide rod 47 in the positioning box 4. In addition, when the to-be-processed fruit 5 is sent into the positioning box 4 from the outlet end of the feeding slide rail 3, the to-be-processed fruit 5 is in the open slot 41, and the open slot 41 can limit the to-be-processed fruit 5. As shown in Figure 5 The cross-section top of the to-be-processed fruit 5 is higher than the highest slide rod 47, and the cross-section bottom is lower than the lowest slide rod 47. Based on this setting, when the guide rod 68 is slidingly matched with the “track” formed by the plurality of slide rods 47, the saw blade 66 can effectively contact the to-be-processed fruit 5 and fix the cutting depth. The low-position slot 461 and the fitting slot 462 enable the guide rod 68 to smoothly transition when switching between different positioning boxes 4, prevent the notch module 6 from jumping, ensure the continuity and stability of the notch, and reduce vibration and error.

[0040] The external motor drives the screw rod 62 to rotate, and based on the thread cooperation between the screw rod 62 and the sliding block 63, the sliding block 63 slides in the tool slide rail 61. When the saw blade 66 and the servo motor 65 are displaced along the array direction of the plurality of positioning boxes 4, the to-be-processed fruit 5 in the plurality of positioning boxes 4 can be continuously subjected to notch operation. It should be noted that due to the possible differences in the size of the to-be-processed fruit 5, based on the sliding cooperation of the guide rod 68 and the “track” formed by the plurality of slide rods 47, the saw blade 66 and the servo motor 65 can be displaced along the axial direction of the guide rod 68 to adapt to the notch operation of the to-be-processed fruit 5 of different sizes. 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 supporting rod 641 will slide into the bottom of the sliding block 63 and press the third spring 69. Based on the third spring 69, it can be ensured that the guide rod 68 always contacts the “track” formed by the fitting block 45 and the plurality of slide rods 47. The screw rod 62 drives the notch module 6 to realize precise linear movement, and the third spring 69 provides flexible buffering, so that the saw blade 66 adapts to the shape change of the to-be-processed fruit 5, improves the consistency of the notch depth, and avoids hard collision and damage to the components.

[0041] The blocking plate arranged at the outlet end of the feeding slide rail 3 can limit the to-be-processed fruit 5 entering the feeding slide rail 3, so that the to-be-processed fruit 5 is temporarily stored at the outlet end of the feeding slide rail 3. Then, when the hydraulic cylinder 2 is output, the output end drives the abutting part 23 to pass through the feeding slide rail 3 and apply pressure to the to-be-processed fruit 5, so that the to-be-processed fruit 5 is pushed from the outlet end of the feeding slide rail 3 into the positioning box body 4. It should be noted that, before the abutting part 23 contacts the to-be-processed fruit 5, the abutting part 22 on the output end of the hydraulic cylinder 2 is limited by the second sliding groove 21 and is extruded to slide on the bottom plate 1 by the abutting part 22, so that the feeding slide rail 3 is displaced in the output direction of the hydraulic cylinder 2, so that the outlet end of the feeding slide rail 3 is connected to the open slot 41 of the positioning box body 4. Then, the abutting part 23 continues to be output and applies pressure to the to-be-processed fruit 5 and extrudes the blocking plate, so that the blocking plate rotates and is embedded in the accommodation slot 42 in the positioning box body 4. Then, the abutting part 23 continues to be output and can extrude the to-be-processed fruit 5 to be transferred from the outlet end of the feeding slide rail 3 to the open slot 41 in the positioning box body 4, so as to realize feeding of the to-be-processed fruit 5 into the positioning box body 4. Based on cooperation of the hydraulic cylinder 2 and the abutting part 23, the to-be-processed fruit 5 in the positioning box body 4 is limited, so that the to-be-processed fruit 5 remains in a fixed state during processing. In addition, it should be noted that, in the initial state, the feeding slide rail 3 does not contact the positioning box body 4, that is, when the classified to-be-processed fruit 5 enters the feeding slide rail 3, the to-be-processed fruit 5 is limited by the blocking plate and is temporarily stored at the outlet end of the feeding slide rail 3. Then, after the hydraulic cylinder 2 is output, the feeding slide rail 3 is extruded by the abutting part 22 and is displaced towards the positioning box body 4, so that the outlet end is connected to the open slot 41. Then, the abutting part 23 continues to be output and extrudes the to-be-processed fruit 5, so as to press the blocking plate to rotate and be embedded in the accommodation slot 42. Then, under pressure, the to-be-processed fruit 5 is moved from the outlet end of the feeding slide rail 3 to the positioning box body 4, and feeding is completed. The abutting part 23 directly contacts the to-be-processed fruit 5 based on the abutting rod 26, and the abutting rod 26 and the abutting part 23 are connected by the first spring 25. Therefore, the extrusion of the to-be-processed fruit 5 is not direct pressure, so that the to-be-processed fruit 5 is not directly broken due to excessive output of the hydraulic cylinder 2. The spline connection improves transmission stability, the first spring 25 buffers pressure to prevent the to-be-processed fruit 5 from being crushed, realizes soft and reliable feeding and fixing, improves processing safety, realizes automatic connection of the feeding slide rail 3 based on the hydraulic cylinder 2, the abutting part 22 and the abutting part 23, ensures smooth transfer of the to-be-processed fruit 5, reduces manual intervention, improves feeding efficiency and positioning accuracy, the blocking plate acts as a one-way valve to ensure orderly feeding of the to-be-processed fruit 5, avoid blockage or repeated feeding, and improve process reliability.
