Description

Technical Field

[0001] This application relates to the field of material production technology, and in particular to a material processing system. Background Technology

[0002] Materials refer to all kinds of raw materials required in the production, manufacturing, or service process. In the production of materials in the food category, cutting fruits in half and removing the pits is a common step, such as in betel nuts, dried apples, and dried apricots.

[0003] In this technique, the operator holds the whole fruit in one hand and cuts it with a blade using the other. After being cut, the fruit is divided into two halves, exposing the pit inside each half. The operator then presses on the outer wall of the half, causing the inner cavity to open. The operator then manually removes the pit using a pitting tool, thus cutting the whole fruit into pieces and removing the pit.

[0004] The above-mentioned method, in which operators hold the whole fruit and cut it to remove the pit, requires multiple actions for each fruit, making the process cumbersome and limiting the number of fruits that can be processed per unit time. This method is difficult to meet the needs of large-scale industrial production, and is both time-consuming and labor-intensive, resulting in low production efficiency. Summary of the Invention

[0005] To address the problem of operators manually handling whole fruits and cutting them to remove pits, which requires multiple actions for each fruit and results in a cumbersome process, a limited number of fruits processed per unit time, and difficulty in meeting the needs of large-scale industrial production, this application provides a material processing system with the following technical solution: It includes a mounting frame equipped with a feeding mechanism, a cutting mechanism, a conveying mechanism, a pitting mechanism, and a discharging mechanism. The feeding mechanism transports the whole fruit to the cutting mechanism, which cuts the whole fruit into two halves. The conveying mechanism sequentially transfers the two halves to the pitting mechanism and the discharging mechanism. The pitting mechanism removes the pit from the inner cavity of each half, and the discharging mechanism discharges the pitted half.

[0006] In one specific implementation scheme, the feeding mechanism includes a vibratory plate mounted on a mounting frame, the discharge end of the vibratory plate being equipped with a conveyor belt, the whole fruit being transported onto the conveyor belt, and the mounting frame being equipped with a first transplanting device for transporting the whole fruit on the conveyor belt to the cutting mechanism.

[0007] In one specific implementation scheme, the cutting mechanism includes a cutting device for cutting materials and a limiting device for fixing materials. The mounting frame is provided with a moving device that drives the whole fruit on the limiting device to cut the whole fruit into two fruit halves through the cutting device.

[0008] In one specific implementation scheme, the conveying mechanism includes a turntable mounted on a mounting frame, the turntable having a receiving device for receiving fruit halves. The mounting frame is sequentially provided with a loading station, a pitting station, and a unloading station. The mounting frame is provided with a first driving unit that drives the receiving device to sequentially move to the loading station, the pitting station, and the unloading station. The receiving device includes a positioning unit and a cavity-opening unit. The cavity-opening unit has a receiving space. The mounting frame is provided with a second transplanting device that transports the fruit halves from the cutting mechanism to the receiving space. The positioning unit pushes and positions the fruit halves within the receiving space.

[0009] In one specific implementation, the second transplanting device includes an insertion unit mounted on a mounting frame. The insertion unit extracts material from the fruit halves by inserting into them. The insertion unit includes a material extraction frame mounted on the mounting frame. The mounting frame is equipped with a moving unit that drives the material extraction frame to move. The material extraction frame is equipped with a needle. The needle inserts into the fruit halves to extract material. The mounting frame is also equipped with a separating unit that drives the needle to move and separates the fruit halves.

[0010] In one specific implementation, the mounting frame is further provided with a detection unit for detecting whether the needle is intact. The detection unit includes an image acquisition component and a data processing component. The image acquisition component acquires image information of the needle after it has detached from the material and transmits the image information to the data processing component. The data processing component processes the image information and determines whether the needle is intact.

[0011] In one specific implementation, the positioning unit includes a push rod disposed on a turntable, and the turntable is provided with a second driving part that drives the push rod to move. The second driving part uses the push rod to push and position the half of the fruit within the receiving space.

[0012] In one specific implementation, the cavity opening unit includes two connecting frames disposed opposite each other on the outer circumferential surface of the turntable. Two connecting rods are respectively provided on the opposite surfaces of the two connecting frames. Each of the two connecting rods is provided with a protrusion. The protrusion is embedded in the inner cavity of the half of the fruit, and a pitting channel is provided between the two protrusions for the pitting end of the pitting mechanism to pass through. The turntable is provided with a driving component that drives the two connecting frames to move towards or away from each other.

[0013] In one specific implementation, the pitting mechanism includes a base mounted on a mounting frame, a support frame rotatably connected to the base, a third driving unit on the base for driving the support frame to rotate, and a pitting device on the support frame for removing the pit from the inner cavity of the fruit half. The pitting device includes a sliding frame slidably connected to the support frame, and a spiked block on the sliding frame. The spiked block and the turntable are offset in the vertical direction, and the spiked block removes the pit from the fruit half from below the turntable through a pitting channel.

[0014] In one specific implementation, the feeding mechanism includes a feeding frame mounted on a mounting frame, a first conveying frame slidably connected to the feeding frame, a second conveying frame slidably connected to the first conveying frame, a feeding device for picking up half of the fruit on the second conveying frame, a first driving device for driving the first conveying frame to slide on the feeding frame, and a second driving device for driving the second conveying frame to slide on the conveying frame.

[0015] In summary, this application has the following beneficial technical effects: When it is necessary to cut and pit the material, the feeding mechanism is activated to transport the whole fruit to the cutting mechanism, the cutting mechanism cuts the whole fruit into two halves, the conveying mechanism transfers the halves to the pitting mechanism and the unloading mechanism in sequence, the pitting mechanism removes the pit from the inner cavity of the half, and the unloading mechanism unloads the pitted half, realizing automated cutting and pitting of the material, replacing the tedious operation of traditional manual hand-held fruit cutting and pitting. The mechanized and automated equipment work together, and the system can continuously and quickly complete the cutting and pitting operations. The number of fruits processed per unit time is much higher than that of manual operation, which greatly improves production efficiency, realizes efficient assembly line production, and meets the needs of large-scale industrial production.

[0033] The following is in conjunction with the appendix Figure 1-16 This application will be described in further detail.

[0034] This application discloses a material processing system.

[0035] Reference Figure 1 and Figure 2The material processing system includes a mounting frame 1, on which are mounted a feeding mechanism 2, a cutting mechanism 3, a conveying mechanism 4, a pitting mechanism 5, and a discharging mechanism 6. The feeding mechanism 2 transports the whole fruit to the cutting mechanism 3, which cuts the whole fruit into two halves. The conveying mechanism 4 sequentially transfers the two halves to the pitting mechanism 5 and the discharging mechanism 6. The pitting mechanism 5 removes the pit from the inner cavity of the half, and the discharging mechanism 6 discharges the pitted half. In this embodiment, the material processing system can be applied to food products, such as yellow peaches and areca nuts. This embodiment uses areca nuts as an example.

[0036] Therefore, when it is necessary to cut and pit the material, the feeding mechanism 2 is activated to transport the whole fruit to the cutting mechanism 3. The cutting mechanism 3 cuts the whole fruit into two halves. The conveying mechanism 4 transfers the two halves to the pitting mechanism 5 and the unloading mechanism 6 in sequence. The pitting mechanism 5 removes the pit from the inner cavity of the half, and the unloading mechanism 6 unloads the pitted half. This realizes the automated cutting and pitting process of the material, replacing the tedious operation of cutting and pitting the fruit manually. The mechanized and automated equipment work together, and the system can continuously and quickly complete the cutting and pitting operations. The number of fruits processed per unit time is much higher than that of manual operation, which greatly improves production efficiency, realizes efficient assembly line production, and meets the needs of large-scale industrial production.

[0037] Reference Figure 2 and Figure 3 The feeding mechanism 2 includes a vibratory plate 7 mounted on the mounting frame 1. In this embodiment, a multi-stage linear vibratory plate 7 is used. The feeding end of the vibratory plate 7 is equipped with a feeding hopper 8, and the discharging end of the vibratory plate 7 is equipped with a conveyor belt 9. The scattered whole areca nuts 17 are fed into the open of the feeding hopper 8. Through vibration, the whole areca nuts 17 are gradually conveyed from high to low onto the conveyor belt 9, thereby realizing the automatic feeding of the whole areca nuts 17.

[0038] Reference Figure 2 and Figure 3 The mounting frame 1 is equipped with a first transplanting device that transports whole fruits from the conveyor belt 9 to the cutting mechanism 3. In this embodiment, the first transplanting device includes a first horizontal straight module 10 mounted on the mounting frame 1, a first vertical straight module 11 mounted on the slide of the first horizontal straight module 10, a transplanting frame 18 mounted on the slide of the first vertical straight module 11, a first parallel finger cylinder 15 mounted on the transplanting frame 18, and grippers 16 on the two slides of the first parallel finger cylinder 15. Whole areca nuts 17 are located between the two grippers 16.

[0039] Therefore, when it is necessary to clamp and transport the whole areca nuts 17 on the conveyor belt 9, the first horizontal linear module 10 and the first vertical linear module 11 are activated to move the transplanting frame 18 to the top of the whole areca nuts 17. At this time, the two grippers 16 are located on both sides of the whole areca nuts 17. The first parallel finger cylinder 15 is activated, which drives the two slides of the first parallel finger cylinder 15 to move relative to each other. The two grippers 16 clamp the whole areca nuts 17 on the conveyor belt 9. Then, the first horizontal linear module 10 and the first vertical linear module 11 are activated to transport the whole areca nuts 17 to the feeding end of the cutting mechanism 3.

[0040] Reference Figure 3 and Figure 4 The cutting mechanism 3 includes a cutting device 12 for cutting materials and a limiting device 14 for fixing materials. A moving device 13 is provided on the mounting frame 1 to drive the whole fruit on the limiting device 14 through the cutting device 12 to cut the whole fruit into two halves. The cutting device 12 includes a blade holder 21 bolted to the mounting frame 1. A blade 22 is mounted on the blade holder 21, with the cutting end of the blade 22 facing the limiting device 14. In this embodiment, the cutting end of the blade 22 is inclined, meaning the height of the second end 20 of the blade 22 is higher than the height of the first end 19. Therefore, when the inclined blade 22 contacts the material, the cutting force gradually transitions from the higher second end 20 to the lower first end 19, forming a progressive cut. This staged force application significantly reduces the instantaneous impact force during the initial cut and extends the service life of the blade 22.

[0041] Reference Figure 3 and Figure 4 The blade holder 21 has a placement hole 23, and an anti-detachment block 24 is fixedly connected to the blade 22. The blade 22 passes through the placement hole 23, and the anti-detachment block 24 is mounted on the blade holder 21. In this embodiment, there are two anti-detachment blocks 24, and the cutting end of the blade 22 is located between the two anti-detachment blocks 24. The anti-detachment blocks 24 limit the position of the blade 22, making the blade 22 stably mounted on the blade holder 21 and reducing the possibility of the blade 22 detaching from the blade holder 21. The anti-detachment blocks 24 also make it easier for the operator to quickly mount the blade 22 on the blade holder 21, improving the convenience of installing the blade 22.

[0042] Reference Figure 3 and Figure 4The tool holder 21 is provided with a limiting unit for limiting the position of the blade 22. The limiting unit includes a top block 25 disposed in the placement hole 23. The blade 22 is pressed against the top block 25 and the hole wall of the placement hole 23. The tool holder 21 is provided with a fixing hole 26. A fixing rod is inserted into the fixing hole 26 and is threaded to the hole wall of the fixing hole 26. The end of the fixing rod facing the top block 25 abuts against the top block 25. In this embodiment, a fixing groove is provided on the surface of the top block 25 facing the fixing rod. The diameter of the fixing groove is slightly larger than the diameter of the fixing rod. The end of the fixing rod facing the top block 25 is inserted into the fixing groove and abuts against the bottom of the fixing groove.

[0043] Therefore, the end of the fixing rod facing the top block 25 is inserted into the fixing groove to reduce the possibility of the top block 25 coming out of the placement hole 23. The end of the fixing rod facing the top block 25 abuts against the bottom of the fixing groove on the top block 25, so that the top block 25 is always in close contact with the blade 22 to limit the position of the blade 22, reducing the possibility of the blade 22 being subjected to force vibration or position displacement during the cutting process, and improving the stability of the blade 22 during the cutting process.

[0044] Reference Figure 3 , Figure 4 and Figure 5 The limiting device 14 includes a fixed frame 27 mounted on the mounting frame 1. The fixed frame 27 has two sets of clamping parts 29, and a support base 28 is bolted to the fixed frame 27. The material is placed on the support base 28 and positioned between the two sets of clamping parts 29. The fixed frame 27 is equipped with a drive unit for moving the two clamping parts 29. The drive unit includes two telescopic components 30 mounted on the fixed frame 27. The telescopic components 30 are located between the clamping parts 29 and the moving device 13. A first connecting frame 31 is mounted on the output end of the telescopic components 30. In this embodiment, the telescopic components 30 can be first telescopic cylinders 32. The first connecting frame 31 is bolted to the output end of the first telescopic cylinder 32, and the two first telescopic cylinders 32 are arranged opposite each other.

[0045] Reference Figure 3 , Figure 4 and Figure 5The clamping part 29 is disposed on the first connecting frame 31. Each of the two sets of clamping parts 29 includes two first limiting blocks 33 mounted on the first connecting frame 31. A connecting rod is mounted on the first connecting frame 31, and both ends of the connecting rod pass through the two first limiting blocks 33. In this embodiment, the number of first limiting blocks 33 in each set of clamping parts 29 can be set according to the actual situation on site. It can be set to one side with a single first limiting block 33 and the other side with two first limiting blocks 33, or the number of first limiting blocks 33 in each set of clamping parts 29 can be set to two or more. In this embodiment, the number of first limiting blocks 33 in each set of clamping parts 29 is set to two as an example. On the opposite surfaces of the two first limiting blocks 33 located in the same set of clamping parts 29, imitation grooves 34 matching the material size are respectively opened. In this embodiment, the shape of the imitation grooves 34 is set according to the shape of the areca nut, and the whole areca nut 17 is located between the four imitation grooves 34.

[0046] Therefore, the two first telescopic cylinders 32 are started simultaneously, which drives the first connecting frame 31 at the output end of the two first telescopic cylinders 32 to move, so that the material is located between the four imitation grooves 34. The imitation grooves 34 limit the position of the areca nut, reduce the possibility of the areca nut position deviation, and improve the stability of the areca nut during the cutting process.

[0047] Reference Figure 3 and Figure 4 The fixed frame 27 is provided with a limiting component to limit the movement of the clamping part 29. The limiting component includes a guide rail 35 disposed on the fixed frame 27, and a guide block 36 of the same size as the guide rail 35 is slidably connected to the guide rail 35. A first limiting block 33 is bolted to the guide block 36. In this embodiment, the four first limiting blocks 33 are arranged opposite each other in pairs. The guide rail 35 limits the movement direction of the guide block 36, reducing the possibility of positional deviation during the movement of the guide block 36 carrying the first limiting blocks 33.

[0048] Reference Figure 3 , Figure 4 and Figure 5A movable component 37 is provided on the fixed frame 27, and an adjusting plate 38 is provided on the movable end of the movable component 37. At least one first limiting block 33 of the clamping part 29 in the same group is provided on the adjusting plate 38. In this embodiment, the movable component 37 can be a finger slide cylinder. The adjusting plate 38 is respectively installed on the two slides of the finger slide cylinder, and the two first limiting blocks 33 of the clamping part 29 in the same group are respectively provided on the two adjusting plates 38. Therefore, when the finger slide cylinder is activated, the adjusting plates 38 on the two slides of the finger slide cylinder slide. Since the first limiting block 33 is installed on the guide block 36, and the guide block 36 is installed on the adjusting plate 38 through the guide rail 35, the distance between the two first limiting blocks 33 in the same group can be adjusted when the two adjusting plates 38 slide, which is convenient for handling betel nuts of different sizes, has greater flexibility, and improves the applicability of the limiting device 14.

[0049] Reference Figure 3 and Figure 4 The moving device 13 includes a second horizontal linear module 39 mounted on the mounting frame 1, and a fixed frame 27 mounted on the slide of the second horizontal linear module 39. The moving direction of the slide of the second horizontal linear module 39 is parallel to the cutting direction of the blade 22. Therefore, activating the second horizontal linear module 39 causes the fixed frame 27 on the slide of the second horizontal linear module 39 to slide, so that the material on the fixed frame 27 passes through the blade 22, and the blade 22 cuts along the central axis of the areca nut to achieve the cutting of the areca nut into pieces.

[0050] When it is necessary to cut areca nuts into pieces, two first telescopic cylinders 32 are activated simultaneously, driving the first connecting frame 31 at the output end of the two first telescopic cylinders 32 to move, so that the areca nuts are positioned between the four grooves 34; the second horizontal linear module 39 is activated, driving the fixed frame 27 on the slide table of the second horizontal linear module 39 to slide, so that the areca nuts on the fixed frame 27 pass through the blade 22, and the blade 22 cuts the areca nuts along the central axis, thereby realizing automated cutting of areca nuts while saving labor costs, reducing the possibility of uneven areca nut cut surfaces caused by manual cutting, saving time and effort, and improving the quality of areca nut cut surfaces and production efficiency.

[0051] In related technologies, the automated cutting of areca nuts often uses quick-release cutters to cut areca nuts one by one on the conveyor line. This method relies on the setting of mechanical cycle time between the positioning process, the moving process and the cutting process. The step-by-step execution method is prone to waste of mechanical cycle time. However, this application achieves the cutting of areca nuts in the process of moving the process, integrating the traditionally separate positioning, moving and cutting processes into a continuous dynamic process, which has significant advantages in terms of efficiency and maintenance cost.

[0052] Reference Figure 6 and Figure 7The conveying mechanism 4 includes a turntable 40 mounted on the mounting frame 1. The turntable 40 is equipped with a receiving device for receiving the fruit halves. The mounting frame 1 is provided with a feeding station 41, a pitting station 42, and a discharging station 43 in sequence. The mounting frame 1 is provided with a first driving unit that drives the receiving device to move sequentially to the feeding station 41, the pitting station 42, and the discharging station 43. The receiving device includes a positioning unit and an opening unit. The opening unit is provided with a receiving space 45. The mounting frame 1 is provided with a second transplanting device 44 that transports the fruit halves of the cutting mechanism 3 to the receiving space 45. The positioning unit pushes and positions the fruit halves within the receiving space 45.

[0053] The turntable 40 adopts a circular layout, with the loading station 41, pitting station 42, and unloading station 43 arranged around it, highly integrating the space requirements of each process. The rotational motion of the turntable 40 replaces the long-distance movement of the robotic arm in related technologies, requiring material transfer only within the circular area, significantly shortening the longitudinal length of the production line, significantly reducing the occupation of factory space, and improving the production efficiency per unit area. Using the turntable 40 to transport the fruit halves improves space utilization, while the periodic rotation of the turntable 40 ensures that the receiving device arrives at each station sequentially at a fixed pace, shortening the material transfer time on the circular path. The synchronous operation of each station around the turntable 40 eliminates the redundant time of the robotic arm's back-and-forth movement, achieving highly efficient "on-demand processing" and improving overall production efficiency.

[0054] Reference Figure 6 and Figure 7 In this embodiment, the number of receiving devices is set to three as an example. The turntable 40 has six mounting surfaces along its rotation direction, and the three receiving devices are spaced apart on three of these surfaces. Operators can also adjust the number of mounting surfaces and receiving devices on the turntable 40 according to the mechanical rhythm of material production. Therefore, through the design of six evenly distributed mounting surfaces and three spaced receiving devices, when the turntable 40 rotates, the three receiving mechanisms can sequentially cover the feeding, kernel removal, and unloading stations, matching the process rhythm of areca nut production and achieving continuous cyclic operation. Simultaneously, it optimizes the center of gravity distribution of the turntable 40, improving rotational stability.

[0055] Reference Figure 6 and Figure 7 A buffer device can also be set on the turntable 40 according to the actual situation on site. The buffer device is set between two adjacent receiving devices. In this embodiment, the specific structure of the buffer device is the same as that of the receiving device, that is, the receiving devices are installed on the three mounting surfaces respectively, and the remaining three mounting surfaces can be used as "empty positions". If intermediate processes need to be added in the future, such as cleaning processes, drying processes, etc., new receiving devices can be added on the idle mounting surfaces without redesigning the main structure of the turntable 40, thereby improving the system flexibility and adapting to multiple specifications of materials.

[0056] Reference Figure 6 and Figure 8 The second transplanting device 44 includes an insertion unit mounted on the mounting frame 1. The insertion unit extracts material from the fruit halves by inserting into them. The insertion unit includes a material extraction frame 47 mounted on the mounting frame 1. The mounting frame 1 is equipped with a moving unit that drives the material extraction frame 47 to move. A needle 48 is mounted on the material extraction frame 47. The needle 48 extracts material by inserting into the fruit halves. The needle 48 includes a needle handle 49, a connecting handle 50, and a needle tip 51 arranged in sequence. The needle handle 49, the connecting handle 50, and the needle tip 51 can be set separately or integrally formed. In this embodiment, the needle handle 49, the connecting handle 50, and the needle tip 51 are integrally formed as an example for illustration. An anti-detachment block 24 is fixedly connected to the outer edge of the needle 48. The cut material is located at the end of the needle 48. In this embodiment, the anti-detachment block 24 is disposed on the needle tip 51 and the cut material is located on the needle tip 51. The anti-detachment block 24 increases the friction between the needle tip 51 and the areca nut pieces, reducing the possibility of the areca nut pieces falling off and improving the stability of the needle 48 in the process of picking up the areca nut pieces. The mounting frame 1 is also provided with a material separating unit that drives the needle 48 to move and causes the fruit halves to separate.

[0057] Reference Figure 8 and Figure 9 The moving unit includes a third horizontal linear module 52 mounted on the mounting frame 1, a third vertical linear module 53 mounted on the slide of the third horizontal linear module 52, and a material-picking rack 47 mounted on the slide of the third vertical linear module 53. Therefore, activating the third horizontal linear module 52 moves the third vertical linear module 53 and the material-picking rack 47 on its slide, allowing the material-picking rack 47 to slide horizontally. Activating the third vertical linear module 53 raises and lowers the material-picking rack 47 on its slide. When the third vertical linear module 53 drives the material-picking rack 47 to descend, the needles 48 on the material-picking rack 47 pierce into the fruit half. Subsequently, the material-picking rack 47 rises and moves horizontally under the drive of the third horizontal linear module 52, thus achieving the separate picking of the fruit half by piercing into the fruit half.

[0058] Reference Figure 8 and Figure 9The material distribution unit includes at least two sliders 54 slidably connected to the material receiving frame 47. The material receiving frame 47 is provided with a drive unit for driving the at least two sliders 54 to move. In this embodiment, two sliders 54 are used as an example. Two needles 48 are respectively disposed on the two sliders 54. The drive unit includes a bidirectional lead screw 55 rotatably connected to the material receiving frame 47. Nuts 56 are threaded to both ends of the bidirectional lead screw 55. The two sliders 54 are respectively disposed on the two nuts 56. The material receiving frame 47 is provided with a fourth drive unit for driving the bidirectional lead screw 55 to rotate. One end of the bidirectional lead screw 55 is connected to the output end of the fourth drive unit through a coupling. In this embodiment, the fourth drive unit can be a first drive motor 57. The first drive motor 57 is directly connected to one end of the bidirectional lead screw 55 through a coupling. The coupling absorbs the deviation between the output shaft of the first drive motor 57 and the bidirectional lead screw 55, which facilitates the efficient transmission of the rotational power of the first drive motor 57 to the bidirectional lead screw 55. Alternatively, the fourth drive unit can be a transmission connection between the first drive motor 57 and the end of the bidirectional lead screw 55 through other transmission components. The transmission components can be a transmission wheel and a conveyor belt, or other transmission methods, which will not be elaborated here.

[0059] Therefore, the first drive motor 57 is started, which drives the bidirectional lead screw 55 at the output end of the first drive motor 57 to rotate. The rotation of the bidirectional lead screw 55 drives the two nuts 56 to move relative to or away from each other along the length direction of the bidirectional lead screw 55. During the movement of the nuts 56, the slider 54 and the needle 48 are driven to move, so as to realize the movement of the areca nut pieces on the needle 48.

[0060] Reference Figure 8 and Figure 9 The second transplanting device 44 also includes an adjustment unit for adjusting the placement posture of the cut material. The adjustment unit includes a fifth drive unit respectively disposed on the slider 54. The fifth drive unit drives the needles 48 to rotate, and the needles 48 are connected to the output end of the fifth drive unit. In this embodiment, the fifth drive unit can be a second drive motor 58, and the two needles 48 are respectively disposed at the output ends of the two second drive motors 58. Therefore, after the two needles 48 on the picking rack 47 pierce the two fruit halves respectively, the third vertical linear module 53 drives the picking rack 47 to rise, and the material distribution unit drives the two fruit halves to separate from each other. If it is necessary to adjust the placement posture of the areca nut pieces on the needles 48 according to the actual situation on site, the two second drive motors 58 are started, driving the needles 48 at the output ends of the two second drive motors 58 to rotate respectively, adjusting the areca nut pieces on the two needles 48 to the required placement posture, thereby realizing automatic posture adjustment of the fruit halves on the needles 48. In this embodiment, the areca nut pieces that were originally positioned opposite each other are rotated so that the inner cavity of the areca nut pieces that were originally positioned opposite each other is adjusted to the required angle, thereby facilitating the subsequent process of removing the pit from the inner cavity of the areca nut.

[0061] Reference Figure 1 and Figure 6 The mounting frame 1 is also equipped with a detection unit 46 for detecting whether the needle 48 is intact. The detection unit 46 includes an image acquisition component and a data processing component. The image acquisition component acquires image information of the needle 48 after it has detached from the material and transmits the image information to the data processing component. The data processing component processes the image information and determines whether the needle 48 is intact. In this embodiment, the image acquisition component can be a camera, and the data processing component can be a control terminal. The control terminal is pre-set with image information of the complete needle 48 in the initial state. The camera takes a picture of the needle 48 to obtain real-time image information and transmits the real-time image information to the control terminal. The control terminal compares the real-time image information of the needle 48 taken by the camera with the image information of the complete needle 48. If the real-time image information shows that part of the needle 48 is missing, it indicates that the needle 48 is in an incomplete state.

[0062] It should be noted that the purpose of checking whether the needle 48 is intact is mainly to reduce the possibility of residual metal in betel nuts. In related technologies, food metal detectors are usually used to detect residual metal. However, the detection accuracy of metal detectors is limited, and there is a possibility of missing metal fragments in a small area. For example, metal fragments smaller than 0.4 mm are not easily detected by metal detectors. Furthermore, metal detectors are easily affected by external environmental interference. For example, aluminum foil packaging can cause signal shielding, making it difficult to effectively monitor for accidentally residual metal in betel nuts.

[0063] This application innovatively proposes using image recognition to detect areca nuts. An image acquisition component captures image information of the needles 48 after they have detached from the material. A data processing component processes the image information and determines whether the needles 48 are intact. High-resolution image acquisition enables non-destructive testing, improving the accuracy of areca nut detection and reducing interference from the external environment, thus enhancing applicability. Furthermore, the detection method in this application significantly differs from metal detectors in related technologies. Metal detectors determine the integrity of the needles 48 by detecting the presence of metal inside the areca nut. This application, however, uses an image acquisition component and a data processing component to infer the presence of residue inside the areca nut by detecting the wear and tear of the needles 48. Metal detectors are passive detection methods, only able to detect detached metal fragments, unable to determine whether the needles 48 are about to break or have partially remained in the areca nut. This application's embodiment analyzes the integrity of the needles 48 through high-resolution images, proactively identifying potential problems such as wear, deformation, and micro-cracks in the needles 48, allowing for timely replacement or adjustment of the equipment, reducing the occurrence of metal needle 48 residue, and improving food safety.

[0064] Reference Figure 10 and Figure 11The cavity opening unit includes two connecting frames 63 arranged opposite to each other on the outer circumferential surface of the turntable 40. The two connecting frames 63 in the vertical direction constitute an embedded component. In this embodiment, the number of embedded components is set to two as an example, that is, the cavity opening unit can perform cavity opening operation on two areca nut pieces at a time. Two connecting rods 64 are respectively provided on the opposite surfaces of the two connecting frames 63. A protrusion 65 is fixedly connected to each of the two connecting rods 64. The protrusion 65 is embedded in the inner cavity of the half of the fruit. A pitting channel 70 is provided between the two protrusions 65 for the pitting end of the pitting mechanism 5 to pass through. A needle channel 71 is provided between the two connecting frames 63 for the needle 48 to pass through. A driving assembly is provided on the turntable 40 to drive the two connecting frames 63 to move towards or away from each other. The driving assembly includes a first moving frame 61 and a second moving frame 62 provided on the turntable 40. The two connecting frames 63 located in the same group of embedded components are respectively provided on the first moving frame 61 and the second moving frame 62. That is, the connecting frames 63 and protrusions 65 on the same side are both located on the first moving frame 61, while the connecting frames 63 and protrusions 65 on the other side are both located on the second moving frame 62.

[0065] Reference Figure 10 and Figure 11 The turntable 40 is provided with a driving component that drives the first moving frame 61 and the second moving frame 62 to move relative to or away from each other. The driving component includes a gear 66 provided on the turntable 40. The turntable 40 is provided with a sixth driving part that drives the gear 66 to rotate. The sixth driving part can be a motor. A first rack 67 is bolted to the first moving frame 61 and a second rack 68 is bolted to the second moving frame 62. The gear 66 is located between the first rack 67 and the second rack 68, and the gear 66 meshes with the first rack 67 and the second rack 68 respectively.

[0066] Therefore, the sixth drive unit is activated, driving the gear 66 of the second drive unit to rotate. The rotation of the gear 66 causes the first rack 67 and the second rack 68 to move relative to or away from each other, thereby causing the first shift frame 61 and the second shift frame 62 to move relative to or away from each other. When it is necessary to clamp the areca nut pieces, the first shift frame 61 and the second shift frame 62 drive the connecting frame 63 and the protrusion 65 to move relative to each other, so that the areca nut pieces are clamped between the two connecting frames 63 located in the same group of embedded components, forming a receiving space 45 between the two connecting frames 63 located in the same group of embedded components. When it is necessary to open the inner cavity of the areca nut pieces, the second drive unit is activated again, and the first shift frame 61 and the second shift frame 62 drive the connecting frame 63 and the protrusion 65 to move away from each other. During the movement, the protrusion 65 applies a force to the inner cavity of the areca nut pieces, opening the inner cavity of the areca nut pieces. In this embodiment, the example of the protrusion 65 being embedded in the inner cavity of the half of the fruit is used for illustration. In addition, the connecting rod 64 and the protrusion 65 fixedly connected to the connecting rod 64 can be set as a curved bending block according to the actual situation on site. By increasing the friction between the bending block and the inner cavity of the areca nut slice, the inner cavity of the areca nut slice can be further opened.

[0067] Reference Figure 10 and Figure 11 The positioning unit includes a push rod 59 mounted on a turntable 40. A second driving unit on the turntable 40 drives the push rod 59 to move. The second driving unit uses the push rod 59 to push and position the fruit half within the receiving space 45. In this embodiment, the second driving unit can be a cylinder, with the push rod 59 located at the cylinder's output end. A groove 60 matching the size of the fruit half is formed on the end face of the push rod 59 facing the protrusion 65. The groove 60 can be arc-shaped according to the shape of the areca nut. The arc-shaped groove 60 limits the position of the areca nut slice, reducing the possibility of positional deviation. Simultaneously, the arc-shaped groove 60 adapts to the shape of the areca nut slice, reducing the possibility of the push rod 59 damaging the slice during movement.

[0068] Therefore, after the areca nut pieces are transported to the connecting frame 63, the second drive unit is activated, which drives the push rod 59 at the output end of the second drive unit to extend and push the areca nut pieces against the protrusion 65. At this time, the protrusion 65 is embedded in the inner cavity of the fruit half, which further fixes the position of the areca nut pieces, reduces the possibility of the position of the areca nut pieces shifting during the opening process, and improves the stability of the position of the areca nut pieces.

[0069] Reference Figure 10 and Figure 11 In this embodiment, the turntable 40 is further provided with a buffer unit, and at least one embedded component is mounted on the drive unit via the buffer unit. The buffer unit includes a second telescopic cylinder 69 mounted on the drive unit. In this embodiment, the turntable 40 is provided with two second telescopic cylinders 69, and the connecting frame 63 located below is located at the output end of the second telescopic cylinder 69. Therefore, the flexible contact of the buffer unit reduces hard collisions and reduces the possibility of damage to the surface of the areca nut during clamping. After the areca nut pieces are fed, they press against the output end of the second telescopic cylinder 69. When dealing with large areca nut pieces, the output end of the second telescopic cylinder 69 will slightly retract under force, reducing the possibility of excessive compression of the areca nut.

[0070] It should be noted that the transfer system can also be configured with multiple turntables 40 according to the actual site conditions. Each turntable 40 has a rotation axis, and multiple turntables 40 are arranged in an array along the direction of the rotation axis, thereby enabling simultaneous production of multiple production lines. This is convenient for large-scale, high-capacity food processing scenarios, solving the capacity bottleneck in large-scale production through space optimization. When the pitting mechanism 5 removes the pits from the inner cavity of the areca nut slices, the protrusion 65 keeps the inner cavity of the areca nut slices open, optimizing the pit removal path and reducing pit residue. After the protrusion 65 is embedded in the inner cavity of the areca nut slices, it forms a physical limit, ensuring that the pits are always exposed within the operating range of the pitting mechanism, reducing the problem of missed or incomplete pit removal due to accidental displacement. The protrusion 65 limits the inner cavity of the areca nut slices, and during the opening process, the protrusion 65 applies a uniform lateral force to the areca nut slices, counteracting the reaction force of the pitting mechanism 5 and preventing the material from sliding or rotating during the pit removal process. The arc-shaped groove 60 of the push rod 59 and the two side protrusions 65 form a "three-point clamping" effect, further enhancing the positioning reliability.

[0071] Reference Figure 12 and Figure 13 The pitting mechanism 5 includes a base 72 mounted on a mounting frame 1, a support frame 73 rotatably connected to the base 72, a third drive unit on the base 72 for driving the support frame 73 to rotate, and a pitting device on the support frame 73 for removing the pit from the inner cavity of the fruit half. In this embodiment, the third drive unit is a servo motor 74, and a reducer is mounted on the output end of the servo motor 74. The support frame 73 is mounted on the output end of the reducer. Therefore, activating the third drive unit drives the support frame 73 to rotate relative to the base 72, making the angle of the support frame 73 and the pitting device on the support frame 73 adjustable, thus improving the flexibility of the support frame 73. The pitting device includes a sliding frame 75 slidably connected to the support frame 73, and a spike 80 is mounted on the sliding frame 75. The spike 80 and the turntable 40 are offset in the vertical direction, and the spike 80 removes the pit from the fruit half from below the turntable 40 through the pitting channel 70.

[0072] Reference Figure 12 and Figure 13The pitting device includes a sliding frame 75 slidably connected to a support frame 73. In this embodiment, a first linear module 76 is mounted on the support frame 73, and a second connecting frame 77 is mounted on the sliding table of the first linear module 76. The sliding frame 75 is slidably connected to the second connecting frame 77. A second parallel finger cylinder 79 is mounted on the sliding frame 75. Spikes 80 are bolted to the two sliding tables of the second parallel finger cylinder 79. The spikes 80 remove the pit from the fruit half through the pitting channel 70, i.e., the spikes 80 are the pitting end of the pitting device. Therefore, activating the second parallel finger cylinder 79 causes the spikes 80 on the two sliding tables of the second parallel finger cylinder 79 to move relative to each other. This allows for adjustment of the distance between the two spikes 80 according to the specific production specifications of the fruit half on site, facilitating pitting operations on fruit half of different specifications and improving the applicability of the pitting device.

[0073] Reference Figure 12 and Figure 13 A pneumatic slide table 81 is mounted on the second connecting frame 77 of the support frame 73, and a sliding frame 75 is disposed on the slide table 81. An electric slide table 82 is mounted on the sliding frame 75, and the second parallel finger cylinder 79 and the spike block 80 are disposed on the slide table 82, with the sliding direction of the electric slide table 82 perpendicular to the sliding direction of the pneumatic slide table 81. Therefore, in this embodiment, the first linear module 76 and the pneumatic slide table 81 move in the same direction, forming a two-stage adjustment, further improving the movement range of the spike block 80.

[0074] In addition, the third drive unit is activated to rotate the support frame 73 relative to the base 72, thereby coarsely adjusting the angle of the support frame 73 and the pitting device on the support frame 73. This makes the support frame 73 tilted towards the pitting station 42 of the turntable 40 in this embodiment. Then, by sliding the moving end of the electric slide table 82, the angle at which the piercing block 80 pierces the inner cavity of the areca nut slice can be finely adjusted by ±10°. This makes it easier for the piercing block 80 to adjust the piercing angle according to the different positions of the kernels in the inner cavity of the areca nut slice, making the kernel removal of the piercing block 80 more flexible and improving the applicability of the piercing block 80 to kernel removal from different positions. In this embodiment, two types of adjustments, coarse adjustment and fine adjustment, are used to optimize the insertion path. The coarse adjustment sets the reference angle, and the relative angle between the pitting device and the pitting station 42 of the turntable 40 is quickly adjusted by the overall rotation of the support frame 73 to adapt to the initial position differences of different batches of materials or to meet the macroscopic adjustment needs of the layout of the turntable 40 station. The fine adjustment dynamically corrects the path. The electric slide table 82 drives the piercing block 80 to make a fine adjustment of ±10° to accurately match the actual position of the pit in half of a single fruit, reducing the possibility of pitting failure due to individual differences in materials.

[0075] Reference Figure 12 and Figure 13In this embodiment, the end of the second connecting frame 77 facing the turntable 40 is bolted to a feeding tray 78. The feeding tray 78 is made of food-grade stainless steel and corresponds to the clamping end of the pitting device. In this embodiment, the feeding tray 78 is located below the pitting device, and baffles are fixedly connected to both sides of the feeding tray 78. After the pitting device completes the pitting process, the feeding tray 78 forms a directional dropping area, allowing the separated pits to fall naturally into the collection box below the feeding tray 78, facilitating the collection of the pits. The feeding tray 78 forms a physical isolation between the pitting mechanism 5 and the turntable 40, guiding the direction of pit feeding and blocking accidentally falling and splashing pits, reducing the probability of pits falling into the pitting mechanism 5 in a splashing state, further controlling the direction of pit splashing, reducing mechanical failures and downtime, and improving production efficiency.

[0076] Traditional pitting and separating machines in related technologies use mechanical impact to remove the pits from areca nut pieces. If the impact force is insufficient or the angle is off, the pit may not completely detach from the inner cavity of the piece, resulting in incomplete pitting. Mechanical impact can also easily damage the areca nut pieces, leading to a low yield. The pitting device in this embodiment acts directly on the pit through mechanical clamping, rather than the entire half of the fruit. Combined with the linear movement of the sliding device, it achieves high-precision pit-meat separation, making it particularly suitable for processing high-value materials such as areca nuts. Furthermore, the integrated design incorporates the pitting action into the turntable 40 production line. The sliding movement of the support frame 73 synchronizes with the turntable 40 station, optimizing process efficiency.

[0077] Reference Figure 12 and Figure 13 A crash shield 83 is bolted to the second connecting frame 77. The second parallel finger cylinder 79 is located on the inner edge of the crash shield 83, and the spikes 80 pass through the crash shield 83. The crash shield 83 protects the inner edge of the second parallel finger cylinder 79, reducing the possibility of accidental damage to the second parallel finger cylinder 79. A stripping plate 84 is provided on the crash shield 83, located between the two spikes 80. When facing areca nut pieces of similar size with little difference in the position of the kernel, the spikes 80 can remove the kernel of the areca nut piece by piercing it.

[0078] Reference Figure 14 , Figure 15 and Figure 16 The feeding mechanism 6 includes a feeding frame 85 mounted on the mounting frame 1, a first conveying frame 86 slidably connected to the feeding frame 85, a second conveying frame 87 slidably connected to the first conveying frame 86, a feeding device for picking up half of the fruit on the second conveying frame 87, a first driving device for driving the first conveying frame 86 to slide on the feeding frame 85, and a second driving device for driving the second conveying frame 87 to slide on the first conveying frame 86.

[0079] Reference Figure 14 , Figure 15 and Figure 16 The material handling device includes a third parallel finger cylinder 88 bolted to the second transport frame 87. Material handling blocks 89 are bolted to the two slides of the third parallel finger cylinder 88. The third parallel finger cylinder 88 synchronously drives the two slides to move towards or away from each other. In this embodiment, two third parallel finger cylinders 88 are used as an example, thus allowing for the simultaneous handling of two areca nut pieces at a time. Therefore, when it is necessary to handle the fruit halves on the turntable 40, the third parallel finger cylinder 88 is activated, causing the two material handling blocks 89 to move relative to each other to clamp and fix the areca nut pieces, reducing the possibility of positional displacement of the areca nut pieces during the unloading process.

[0080] Reference Figure 14 , Figure 15 and Figure 16 The second conveying frame 87 is equipped with a telescopic part, and a push block 91 is provided at the output end of the telescopic part. The push block 91 is located between the two material picking blocks 89. In this embodiment, the telescopic part adopts a third telescopic cylinder 90, and the push block 91 is installed at the output end of the third telescopic cylinder 90. Therefore, if the areca nut pieces stick to the material picking block 89 during feeding, the third telescopic cylinder 90 is activated, which drives the push block 91 at the output end of the third telescopic cylinder 90 to extend. The push block 91 applies a force to the areca nut pieces, causing them to fall off the material picking block 89, thus reducing the possibility of the areca nut pieces sticking to the material picking block 89. In addition, since the betel nut slices may have uneven thickness or slight deformation, the clamping surface of the material taking block 89 may have slight misalignment due to wear after long-term use, resulting in uneven gaps. The push block 91 located between the two material taking blocks 89 also plays a role in pre-positioning and can be used as a real-time detection of gap uniformity. If the push block 91 can move smoothly between the two material taking blocks 89 when it extends and retracts, it means that the minimum gap for clamping the betel nut slices meets the actual requirements. If the push block 91 is obstructed from moving, it means that the gap between the material taking blocks 89 is abnormal or there is a deviation, and the position of the third parallel finger cylinder 88 or the material taking block 89 needs to be finely adjusted.

[0081] Reference Figure 14 , Figure 15 and Figure 16The first driving device includes a third linear module 92 mounted on the unloading rack 85, and a first transport frame 86 mounted on the slide of the third linear module 92. The second driving device includes a fourth linear module 93 mounted on the first transport frame 86, and a second transport frame 87 bolted to the slide of the fourth linear module 93. In this embodiment, the fourth linear module 93 is inclined according to the actual situation of the turntable 40 station. Therefore, when it is necessary to transport and unload the fruit half on the turntable 40, the third parallel finger cylinder 88 is activated, which drives the two picking blocks 89 to move relative to each other to clamp and fix the areca nut pieces. Then, the fourth linear module 93 is activated to drive the second transport frame 87 to slide along the first transport frame 86, and the third linear module 92 is activated to drive the first transport frame 86 to slide along the mounting frame 1. The displacement and unloading of the fruit half on the picking block 89 is achieved through two-stage sliding.

[0082] Reference Figure 14 , Figure 15 and Figure 16 A mounting plate 96 is rotatably connected to the first transport frame 86. A fourth linear module 93 is mounted on the mounting plate 96. A fixing unit is provided on the first transport frame 86 to connect the mounting plate 96 to the first transport frame 86. The fixing unit includes several mounting bolts 97 that pass through the mounting plate 96. Several mounting holes 98 are opened on the first transport frame 86, and the several mounting bolts 97 are threaded into the several mounting holes 98 respectively. A second limiting block 99 is bolted to the mounting plate 96. A limiting seat 100 is bolted to the first transport frame 86. A limiting rod 101 passes through and is threaded to the limiting seat 100. One end of the limiting rod 101 facing the second limiting block 99 contacts the second limiting block 99. In this embodiment, the number of limiting seats 100 and limiting rods 101 mounted on the limiting seats 100 is set to two, and the second limiting block 99 is located between the two limiting seats 100.

[0083] Reference Figure 14 , Figure 15 and Figure 16 An angle ruler 102 is engraved on the mounting plate 96, and an indicator 103 matching the angle ruler 102 is engraved on the first transport frame 86. The end of the indicator 103 corresponds to the angle ruler 102. In this embodiment, according to the tilt angle of the station on the turntable 40, when the end of the indicator 103 is aligned with 90 degrees of the angle ruler 102, the two picking blocks 89 at the moving end of the third parallel finger cylinder 88 have the best clamping accuracy for the areca nut slices on the turntable 40. The angle ruler 102 and the indicator 103 make it easy for the operator to clearly and intuitively know the tilt of the fourth linear module 93 on the mounting plate 96.

[0084] Therefore, the mounting plate 96 can rotate relative to the first transport frame 86, thereby adjusting the tilt angle of the fourth linear module 93 on the mounting plate 96. When the end of the indicator 103 on the first transport frame 86 is aligned with 90 degrees of the angle ruler 102 on the mounting plate 96, it indicates that the tilt of the fourth linear module 93 on the mounting plate 96 is optimal. The operator installs the mounting plate 96 on the first transport frame 86 by bolt connection. At the same time, the two limit rods 101 limit the vertical position of the second limit block 99 on the mounting plate 96, further improving the stability of the mounting plate 96 on the first transport frame 86.

[0085] Reference Figure 14 , Figure 15 and Figure 16 A qualified bin 94 and a defective bin 94 are provided between the mounting frame 1 and the turntable 40. Each of the qualified and defective bins 94 has a receiving port located on its sliding path along the second transport frame 87. In this embodiment, the mounting frame 1 is also equipped with an image unit, which includes an image acquisition unit and a data processing unit. The image acquisition unit can be an image acquisition device such as a camera or webcam. In this embodiment, a camera is used. The camera captures image information of the areca nut slices and transmits this image information to the data processing unit. The data processing unit compares this image information with a standard template to determine whether the areca nut slices have defects. If defects are present, the slices are defective; otherwise, they are qualified. The qualified bin 94 and the unqualified bin 94 are each equipped with a guide pipe 104. The design of the guide pipe 104 further optimizes the spatial layout and improves the compactness of the structure. Qualified areca nut pieces fall into the qualified bin 94 from the receiving port and are separated by the guide pipe 104. Unqualified areca nut pieces fall into the unqualified bin 94 from the receiving port and are separated by the guide pipe 104. This realizes the automated sorting of areca nut pieces, improves production efficiency, and reduces labor costs.

[0086] The implementation principle of this application embodiment is as follows: When it is necessary to cut and pit the whole areca nuts 17, the scattered whole areca nuts 17 are put into the feed hopper 8 through the open end. The vibrating plate 7 gradually conveys the whole areca nuts 17 from high to low to the conveyor belt 9 through vibration. When it is necessary to clamp and transport the whole areca nuts 17 on the conveyor belt 9, the first horizontal linear module 10 and the first vertical linear module 11 are activated to move the transplanting frame 18 to the top of the whole areca nuts 17. At this time, the two grippers 16 are located on both sides of the whole areca nuts 17. The first parallel finger cylinder 15 is activated to drive the two slides of the first parallel finger cylinder 15 to move relative to each other. The two grippers 16 clamp the whole areca nuts 17 on the conveyor belt 9. Then the first horizontal linear module 10 and the first vertical linear module 11 are activated to transport the whole areca nuts 17 to the support seat 28 of the cutting mechanism 3. Two first telescopic cylinders 32 are activated simultaneously, driving the first connecting frame 31 at the output end of the two first telescopic cylinders 32 to move, so that the areca nut is positioned between the four grooves 34; the second horizontal linear module 39 is activated, driving the fixed frame 27 on the slide table of the second horizontal linear module 39 to slide, so that the areca nut on the fixed frame 27 passes through the blade 22, and the blade 22 cuts the areca nut along the central axis, thereby realizing automated cutting of areca nut while saving labor costs, reducing the possibility of uneven areca nut cut surface caused by manual cutting, saving time and effort, and improving the quality of areca nut cut surface and production efficiency; The third horizontal linear module 52 is activated, which moves the third vertical linear module 53 and the picking rack 47 on the slide of the third horizontal linear module 52, enabling the picking rack 47 to slide horizontally. The third vertical linear module 53 is activated, which raises and lowers the picking rack 47 on the slide of the third vertical linear module 53. When the picking rack 47 is lowered by the third vertical linear module 53, the needles 48 on the picking rack 47 pierce into the fruit half. Then the picking rack 47 rises and moves horizontally under the drive of the third horizontal linear module 52, thereby achieving the picking of the fruit half by piercing into the fruit half. The first drive motor 57 is activated, which drives the bidirectional lead screw 55 at the output end of the first drive motor 57 to rotate. The rotation of the bidirectional lead screw 55 drives the two nuts 5 6. The screw 55 moves relative to or away from each other along its length. During the movement of the nut 56, the slider 54 and the needle 48 move, thereby moving the areca nut pieces on the needle 48 and separating the two areca nut pieces that were originally in contact. The two second drive motors 58 are started, which drive the needles 48 at the output ends of the two second drive motors 58 to rotate respectively, adjusting the areca nut pieces on the two needles 48 to the preset placement posture, thereby achieving automatic posture adjustment of the fruit half on the needles 48, so that the areca nut pieces are placed on the connecting frame 63 with the inner cavity opening facing the protrusion 65. Then the third horizontal linear module 52 and the third vertical linear module 53 are started to transport and place the posture-adjusted areca nut pieces on the connecting frame 63 located below. When it is necessary to clamp the areca nut pieces, the sixth drive unit is activated, which drives the gear 66 of the second drive unit to rotate. The rotation of the gear 66 causes the first rack 67 and the second rack 68 to move relative to each other. The first shift frame 61 and the second shift frame 62 drive the connecting frame 63 and the protrusion 65 to move relative to each other, so that the areca nut pieces are clamped between the two connecting frames 63 located in the same group of embedded components, forming a receiving space 45 between the two connecting frames 63 located in the same group of embedded components. After the areca nut pieces are clamped between the two connecting frames 63, the third horizontal linear module 52 and the third vertical linear module 53 are activated, which drives the needle 48 from the two connecting rods 64. The needle path 71 moves and detaches from the areca nut slice; the second drive unit is activated, causing the push rod 59 at the output end of the second drive unit to extend and push the areca nut slice against the protrusion 65. At this time, the protrusion 65 is embedded in the inner cavity of the fruit half, further fixing the position of the areca nut slice; when it is necessary to open the inner cavity of the areca nut slice, the second drive unit is activated again, and the first moving frame 61 and the second moving frame 62 drive the connecting frame 63 and the protrusion 65 to move in opposite directions. Since the protrusion 65 is embedded in the inner cavity of the fruit half, the protrusion 65 applies force to the inner cavity of the areca nut slice during the movement, opening the inner cavity of the areca nut slice. The first drive unit is activated to rotate the turntable 40, moving the areca nut slices to the pitting station 42. The third drive unit is activated to rotate the support frame 73 relative to the base 72, achieving coarse adjustment of the angle of the support frame 73 and the pitting device on the support frame 73. The first linear module 76 and the pneumatic slide table 81 are activated to move the support frame 73 toward the areca nut slices, simultaneously inserting the two spikes 80 into the pits of the areca nut slices. According to the actual situation on site, the electric slide table 82 can be activated to finely adjust the position of the spikes 80 on the second parallel finger cylinder 79, thereby finely adjusting the insertion angle of the spikes 80 according to the position of the pit. Then, the first linear module 76 and the pneumatic slide 81 are driven again to reset the support frame 73. During the movement, the fruit pits on the two spikes 80 come into contact with the stripping plate 84. At this time, the fruit pits are located at the top of the feeding tray 78. The stripping plate 84 acts as a blocking and limiting function for the fruit pits, stripping the fruit pits from the spikes 80. The stripped fruit pits fall into the feeding tray 78 for feeding. The first drive unit is activated to rotate the turntable 40, moving the areca nut slices to the unloading station 43. The third parallel finger cylinder 88 is activated to move the two picking blocks 89 relative to each other to clamp and fix the areca nut slices on the turntable 40. Then, the fourth linear module 93 is activated to move the second transport frame 87 along the first transport frame 86. The third linear module 92 is activated to move the first transport frame 86 along the mounting frame 1, thereby realizing the displacement of the areca nut slices after kernel removal. The qualified areca nut slices held by the picking blocks 89 are moved to the qualified barrel 94, and the unqualified areca nut slices held by the picking blocks 89 are moved to the unqualified barrel 94. The third parallel finger cylinder 88 is activated again to move the two picking blocks 89 in opposite directions to release the clamping of the areca nut slices, realizing the automatic unloading of the areca nut slices.
