Description

Technical Field

[0001] This application relates to the field of material production technology, and in particular to a material cavity opening 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] After the whole fruit is cut with a blade, it is divided into two halves, exposing the pit inside the half. To facilitate subsequent pit removal, the half's cavity needs to be opened beforehand. Related technologies employ two opposing cylinders, each with a pusher block mounted on its output end. The half of the fruit is positioned between the two pushers. Simultaneous activation of the two cylinders compresses the half, causing deformation and opening its internal cavity.

[0004] The above-mentioned method of using a cylinder to push and squeeze to open the inner cavity of half of the fruit is difficult to control precisely. Excessive pressure can easily cause cracks or breakage in the half of the fruit, affecting the integrity rate of the finished product. Summary of the Invention

[0005] To address the problem that the method of opening the inner cavity of a fruit half by squeezing with a cylinder is difficult to control precisely, and that excessive pressure can easily cause cracks or breakage in the fruit half, affecting the integrity of the finished product, this application provides a material cavity opening system with the following technical solution: It includes a mounting frame, on which are provided a feeding mechanism for feeding the fruit half and a receiving mechanism for receiving the fruit half. The receiving mechanism includes a positioning device and a cavity opening device. The positioning device is used to limit the position of the fruit half, and the cavity opening device is used to open the inner cavity of the positioned fruit half.

[0006] In one specific implementation, the cavity opening device includes two connecting frames arranged opposite each other on the mounting frame, two connecting rods are respectively provided on the opposite surfaces of the two connecting frames, and protrusions are respectively provided on the four connecting rods. The mounting frame is provided with a drive unit for driving the two connecting frames to move towards or away from each other.

[0007] In one specific implementation, the drive unit includes a first moving frame and a second moving frame disposed on the mounting frame, and two connecting frames are respectively disposed on the first moving frame and the second moving frame. The mounting frame is provided with a first drive part for driving the first moving frame and / or the second moving frame to move.

[0008] In one specific implementation, the positioning device includes a push rod disposed on a mounting frame, and the mounting frame 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 against the cavity opening device.

[0009] In one specific implementation, the feeding mechanism includes a feeding device for taking material from the fruit halves and a conveying device for driving the feeding device to move. The feeding device includes at least two piercing units for taking material from the fruit halves and a dispensing unit for driving the piercing units to separate.

[0010] In one specific implementation, the piercing unit includes a support frame mounted on a mounting bracket, the support frame having a piercing needle, with half of the fruit located at the end of the piercing needle.

[0011] In one specific implementation, the material dispensing unit includes at least two sliders slidably connected to a support frame, the needles being respectively disposed on the sliders, and the support frame being provided with a drive assembly for driving the at least two sliders to move.

[0012] In one specific implementation, the feeding device further includes an adjustment unit for adjusting the placement posture of the fruit half. The adjustment unit includes a third drive unit respectively disposed on the slider. The third drive unit drives the needle to rotate, and the needle is connected to the output end of the third drive unit.

[0013] In one specific implementation scheme, a cavity-opening method for the above-mentioned material cavity-opening system is characterized in that the method includes: The feeding mechanism feeds half of the fruit onto the opening device of the receiving mechanism; The start-up drive unit drives the two connecting frames to move towards each other, clamping half of the fruit between the two connecting frames; The feeding mechanism separates from the opening device of the discharging and receiving mechanism and separates from the half of the fruit; The second drive unit is activated to extend the push rod, pushing the fruit half against the four connecting rods so that the protrusion is embedded in the inner cavity of the fruit half. Restarting the drive unit causes the two connecting frames to move in opposite directions, which in turn causes the protrusions on the two connecting frames to open up half of the fruit's inner cavity.

[0014] In one specific feasible implementation, the steps of the feeding mechanism feeding half of the fruit to the receiving mechanism include: The transport device is activated to move the support frame, causing the two needles on the support frame to pierce into the two halves of the fruit respectively; The drive unit is activated, causing the two sliders to move in opposite directions, thus separating the fruit halves on the needles. The two third drive units are activated respectively to drive the two needles to rotate in a preset direction and a preset distance to adjust the placement of the fruit half; The transport device is activated to move the support frame, which in turn moves the needles on the support frame between the two connecting rods on the same connecting frame, thus placing half of the fruit on the connecting frame located below. The steps involved in separating the feeding mechanism from the opening device of the discharging and receiving mechanism and separating the fruit half include: The start of the transport device moves the support frame, causing the needles on the support frame to move between the two connecting rods and detach from the fruit half.

[0015] In summary, this application has the following beneficial technical effects: when it is necessary to open the inner cavity of the fruit half, the feeding mechanism is activated to feed the material to the receiving mechanism, the positioning device is activated to limit the position of the fruit half, and then the cavity opening device is activated to open the inner cavity of the fruit half, thereby realizing the automated cavity opening of the fruit half. The cavity opening method of opening the inner cavity of the fruit half by using the cavity opening device reduces the possibility of the pulp fibers being crushed due to the cylinder squeezing of the fruit half in related technologies, reduces the risk of fruit half cracking, and improves the product yield of the fruit half.

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses a material opening system.

[0024] Example 1 Reference Figure 1 and Figure 2 The material cavity-opening system includes a mounting frame 1, on which a feeding mechanism 2 for feeding the fruit half and a receiving mechanism 3 for receiving the fruit half are mounted. The mounting frame 1 can be a separate unit or a single piece. In this embodiment, the mounting frame 1 is a single-piece frame. Both the feeding mechanism 2 and the receiving mechanism 3 are mounted on the mounting frame 1, with the feeding mechanism 2 located on one side of the receiving mechanism 3. The receiving mechanism 3 includes a positioning device and a cavity-opening device. The positioning device limits the position of the fruit half, and the cavity-opening device is used to open the inner cavity of the positioned fruit half. In this embodiment, the material cavity-opening system can be applied to food materials, such as yellow peaches and areca nuts. In this embodiment, areca nuts are cut into two pieces by a cutting process as an example.

[0025] Therefore, when it is necessary to open the inner cavity of the fruit half, the feeding mechanism 2 is activated to feed the material to the receiving mechanism 3, the positioning device is activated to limit the position of the fruit half, and then the cavity opening device is activated to open the inner cavity of the fruit half, realizing the automated cavity opening of the fruit half. This cavity opening method, which uses a cavity opening device to open the inner cavity of the fruit half, reduces the possibility of crushing the fruit pulp fibers caused by cylinder compression of the fruit half in related technologies, lowers the risk of fruit half cracking, and improves the yield of fruit half products.

[0026] Reference Figure 2 and Figure 3 The cavity-opening device includes two connecting frames 4 arranged opposite each other on the mounting frame 1. In this embodiment, the two connecting frames 4 are vertically aligned on the same straight line. Two connecting rods 5 are fixedly connected to the opposite surfaces of the two connecting frames 4, and protrusions 6 are fixedly connected to the four connecting rods 5 respectively. The mounting frame 1 is provided with a driving unit that drives the two connecting frames 4 to move towards or away from each other. The areca nut slice contacts the connecting rods 5, and the protrusions 6 are embedded in the inner cavity of the areca nut slice. The driving unit includes a first moving frame 7 and a second moving frame 8 arranged on the mounting frame 1. The two connecting frames 4 are respectively arranged on the first moving frame 7 and the second moving frame 8. The mounting frame 1 is provided with a first driving part that drives the first moving frame 7 and the second moving frame 8 to move towards or away from each other. The first drive unit includes a gear 14 mounted on a mounting frame 1. A first drive motor that drives the gear 14 to rotate is mounted on the mounting frame 1. A first rack 15 is bolted to a first moving frame 7, and a second rack 16 is bolted to a second moving frame 8. The first rack 15 and the second rack 16 are arranged in parallel. The gear 14 is located between the first rack 15 and the second rack 16, and the gear 14 meshes with the first rack 15 and the second rack 16.

[0027] Therefore, the first drive motor is started, which drives the gear 14 at the output end of the first drive motor to rotate. The rotation of the gear 14 drives the first rack 15 and the second rack 16 to move relative to or away from each other, thereby causing the first moving frame 7 and the second moving frame 8 to move relative to or away from each other. When it is necessary to clamp the areca nut pieces, the first drive motor is started, and the first moving frame 7 and the second moving frame 8 move relative to each other, so that the areca nut pieces are clamped between the two connecting frames 4, thereby achieving vertical positioning of the areca nut pieces.

[0028] In this embodiment, a telescopic cylinder 18 is bolted to the first shifting frame 7. The connecting frame 4 located below is installed at the output end of the telescopic cylinder 18. The flexible contact of the telescopic cylinder 18 reduces hard collisions and minimizes the possibility of damage to the areca nut surface during clamping. After the areca nut pieces are fed, they rest against the connecting frame 4 at the output end of the telescopic cylinder 18. When dealing with large areca nut pieces, the output end of the telescopic cylinder 18 will slightly retract under force, reducing the possibility of excessive compression of the areca nut.

[0029] Reference Figure 2 and Figure 3 The positioning device includes a push rod 9 mounted on a mounting frame 1. The mounting frame 1 has a second driving unit that drives the push rod 9 to move. The second driving unit uses the push rod 9 to push and position the fruit half against the opening device. In this embodiment, the second driving unit can be a cylinder, with the push rod 9 located at the cylinder's output end. A groove 17 matching the size of the areca nut slice is provided on the end face of the push rod 9 facing away from the second driving unit. The groove 17 can be arc-shaped according to the shape of the areca nut. The arc-shaped groove 17 limits the position of the areca nut slice, reducing the possibility of positional deviation. Simultaneously, the arc-shaped groove 17 adapts to the shape of the areca nut slice, reducing the possibility of the push rod 9 damaging the areca nut slice during movement.

[0030] Therefore, after the areca nut slices are clamped between the two connecting frames 4, the second drive unit is activated, causing the push rod 9 at the output end of the second drive unit to extend and push the areca nut slices against the four connecting rods 5. At this time, the protrusion 6 is embedded in the inner cavity of the fruit half, which further fixes the position of the areca nut slices, reduces the possibility of the position of the areca nut slices shifting during the cavity opening process, and improves the stability of the position of the areca nut slices. In this embodiment, the example of the protrusion 6 being embedded in the inner cavity of the areca nut slices is used for illustration. In addition, according to the actual situation on site, the connecting rods 5 and the protrusion 6 fixedly connected to the connecting rods 5 can be set as a curved bending block. By increasing the friction between the bending block and the inner cavity of the areca nut slices, the cavity opening of the inner cavity of the areca nut slices can be further realized.

[0031] Reference Figure 4 and Figure 5The feeding mechanism 2 includes a feeding device for picking up fruit halves and a conveying device for driving the feeding device to move. The feeding device includes at least two piercing units for picking up fruit halves and a distributing unit for driving the piercing units to separate. The piercing unit includes a support frame 10 mounted on the mounting frame 1. A needle 11 is mounted on the support frame 10. The needle 11 includes a needle handle 19, a connecting handle 20, and a needle tip 21 arranged sequentially. The needle handle 19, the connecting handle 20, and the needle tip 21 can be separately arranged or integrally formed. In this embodiment, the needle handle 19, the connecting handle 20, and the needle tip 21 are integrally formed as an example. The fruit halves are located at the end of the needle tip 21. The two connecting rods 5 at the top form a needle path 28 for the needle 11 to pass through. An anti-detachment block is fixedly connected to the outer edge of the needle 11. Half of the fruit is located at the end of the needle 11. In this embodiment, the anti-detachment block is set on the needle tip 21 and the half of the fruit is located on the needle tip 21. The anti-detachment block increases the friction between the needle tip 21 and the areca nut pieces, reduces the possibility of the areca nut pieces falling off, and improves the stability of the needle 11 in the process of picking up the areca nut pieces.

[0032] Reference Figure 4 and Figure 5 The conveying device includes a horizontal linear module 22 mounted on a mounting frame 1, a vertical linear module 23 mounted on a slide of the horizontal linear module 22, and a support frame 10 mounted on the slide of the vertical linear module 23. Therefore, activating the horizontal linear module 22 moves the vertical linear module and the support frame 10 on its slide, allowing the support frame 10 to slide horizontally. Activating the vertical linear module 23 raises and lowers the support frame 10 on its slide. When the vertical linear module 23 drives the support frame 10 to descend, the needles 11 on the support frame 10 pierce the fruit half. Subsequently, the support frame 10 rises and moves horizontally under the drive of the horizontal linear module 22, thus achieving separate fruit half-section extraction by piercing the fruit half.

[0033] Reference Figure 4 and Figure 5The material distribution unit includes at least two sliders 12 slidably connected to a support frame 10. Needles 11 are respectively disposed on the sliders 12. A drive assembly for driving the movement of at least two sliders 12 is provided on the support frame 10. In this embodiment, two sliders 12 are used as an example, and two needles 11 are respectively disposed on two sliders 12. The drive assembly includes a bidirectional lead screw 24 rotatably connected to the support frame 10. Nuts are threaded onto the bidirectional lead screw 24, and the two sliders 12 are respectively disposed on two nuts. A fourth drive unit 25 for driving the bidirectional lead screw 24 to rotate is provided on the support frame 10. One end of the bidirectional lead screw 24 is connected to the output end of the fourth drive unit 25 via a coupling. In this embodiment, the fourth drive unit 25 can be a second drive motor. The second drive motor is directly connected to one end of the bidirectional lead screw 24 via a coupling. The coupling absorbs the deviation between the output shaft of the second drive motor and the bidirectional lead screw 24, which facilitates the efficient transmission of the rotational power of the second drive motor to the bidirectional lead screw 24. Alternatively, the fourth drive unit 25 can be a second drive motor connected to the end of the bidirectional lead screw 24 via 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.

[0034] Therefore, the second drive motor is started, which drives the bidirectional lead screw 24 at the output end of the second drive motor to rotate. The rotation of the bidirectional lead screw 24 drives the two nuts to move relative to each other or in opposite directions along the length of the bidirectional lead screw 24. During the movement of the nuts, the slider 12 and the needle 11 are moved. When the two nuts move in opposite directions, the areca nut pieces on the two needles 11 are separated from each other.

[0035] Reference Figure 4 and Figure 5 In this embodiment, the support frame 10 is bolted with a guide rail 26 that is parallel to the bidirectional lead screw 24. Two guide blocks 27 that match the size of the guide rail 26 are slidably connected on the guide rail 26. Two sliders 12 are respectively set on the two guide blocks 27. The guide rail 26 limits the sliding direction of the guide blocks 27, which further improves the stability of the movement of the nut and the spike 11 on the nut.

[0036] Reference Figure 4 and Figure 5The material handling device also includes a posture adjustment unit for adjusting the placement posture of the fruit halves. The posture adjustment unit includes a third drive unit 13 respectively disposed on the slider 12. The third drive unit 13 drives the needles 11 to rotate, and the needles 11 are connected to the output end of the third drive unit 13. In this embodiment, the third drive unit 13 can be a third drive motor, and the two needles 11 are respectively disposed at the output ends of the two third drive motors. Therefore, after the two needles 11 on the support frame 10 are inserted into the two fruit halves, the vertical linear module 23 drives the support frame 10 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 11 according to the actual situation on site, the two third drive motors are started, driving the needles 11 at the output ends of the two third drive motors to rotate a preset distance in a preset direction, adjusting the areca nut pieces on the two needles 11 to the required placement posture, thereby realizing automatic posture adjustment of the fruit halves on the needles 11. 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.

[0037] In this embodiment, the mounting frame 1 is further provided with a detection mechanism for detecting whether the needle 11 is intact. The detection mechanism includes an image acquisition unit and a data processing unit. The image acquisition unit acquires image information of the needle 11 after it has detached from the material and transmits the image information to the data processing unit. The data processing unit processes the image information and determines whether the needle 11 is intact. In this embodiment, the image acquisition unit can be a camera, and the data processing unit can be a control terminal. The control terminal is pre-set with image information of the complete needle 11 in the initial state. The camera takes a picture of the needle 11 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 11 taken by the camera with the image information of the complete needle 11. If the real-time image information shows that part of the needle 11 is missing, it indicates that the needle 11 is in an incomplete state.

[0038] It should be noted that the purpose of checking whether the needle 11 is intact is mainly to reduce the possibility of residual metal in the areca nut. 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 the areca nut. This application innovatively proposes using image recognition to detect areca nuts. An image acquisition unit acquires image information of the needle 11 after it has detached from the material, and a data processing unit processes the image information to determine the integrity of the needle 11. 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 needle 11 by detecting the presence of metal inside the areca nut, while this application uses an image acquisition unit and a data processing unit to infer the presence of residue inside the areca nut by detecting needle 11 wear. Metal detectors are passive detection methods, only able to detect detached metal fragments, unable to determine whether the needle 11 is about to break or has partially remained in the areca nut. This application's embodiment analyzes the integrity of the needle 11 through high-resolution image analysis, proactively identifying potential problems such as needle 11 wear, deformation, and micro-cracks, allowing for early replacement or adjustment of equipment, reducing the occurrence of metal needle 11 residue, and improving food safety.

[0039] The implementation principle of this application embodiment is as follows: The horizontal linear module 22 is activated, driving the vertical linear module 23 and support frame 10 on the slide of the horizontal linear module 22 to move, realizing the horizontal sliding of the support frame 10. The vertical linear module 23 is activated, driving the support frame 10 on the slide of the vertical linear module 23 to rise and fall. When the vertical linear module 23 drives the support frame 10 to fall, the two needles 11 on the support frame 10 respectively pierce into the two areca nut pieces. Subsequently, the support frame 10 rises and moves horizontally under the drive of the horizontal linear module 22, thereby realizing the extraction of material from the two areca nut pieces by piercing the half of the fruit. After the two needles 11 extract material from the two areca nut pieces, the second drive motor is activated, driving the bidirectional lead screw 24 at the output end of the second drive motor to rotate. The rotation of the bidirectional lead screw 24 drives... Two nuts move in opposite directions along the length of the bidirectional lead screw 24. During the movement of the nuts, the slider 12 and the needle 11 move, causing the areca nut pieces on the needle 11 to move and separate the two areca nut pieces that were originally in a close-fitting state, thus realizing the automated feeding of areca nut pieces. If the placement posture of the areca nut pieces on the needle 11 needs to be adjusted according to the actual situation on site, the two third drive motors are started respectively, driving the needle 11 at the output end of the two third drive motors to rotate, adjusting the areca nut pieces on the needle 11 to the preset placement posture, realizing the automatic posture adjustment of the fruit half on the needle 11, so that the placement posture of the areca nut pieces when they are placed on the connecting frame 4 is such that the inner cavity opening faces the protrusion 6. The horizontal linear module 22 is started to transport and place the posture-adjusted areca nut pieces on the connecting frame 4 located below the receiving mechanism 3. Then, the first drive motor is started, driving the gear 14 at the output end of the first drive motor to rotate. The rotation of gear 14 causes the first rack 15 and the second rack 16 to move relative to each other, thereby causing the first moving frame 7 and the second moving frame 8 to move relative to each other, so that the areca nut slice is clamped between the two connecting frames 4, achieving vertical positioning of the areca nut slice; after the areca nut slice is clamped between the two connecting frames 4, the vertical straight module 23 is started, driving the support frame 10 on the slide of the vertical straight module 23 to rise, and the needle 11 moves from the needle track 28 between the two connecting rods 5 and disengages from the areca nut slice; the first drive motor 7 is started, driving the gear 14 at the output end of the first drive motor to rotate. The gear 14 rotates, driving the gear 15 to rotate, driving the gear 16 to rotate, causing the gear 16 to rotate, driving the gear 17 to rotate, driving the gear 18 to rotate, driving ...8 to rotate, driving the gear 16 to rotate, driving the gear 17 to rotate, driving the gear 18 to rotate, driving the gear 18 to rotate, driving the gear 16 The second drive unit extends the push rod 9 at its output end, pushing the areca nut slices against the four connecting rods 5. At this time, the protrusion 6 is embedded in the inner cavity of the fruit half, further fixing the position of the areca nut slices. Then, the first drive motor is restarted, and the first and second moving frames 7 and 8 drive the protrusion 6 to move in opposite directions. Since the protrusion 6 is embedded in the inner cavity of the fruit half, it applies force to the inner cavity of the areca nut slices during movement, opening the inner cavity and achieving automated cavity opening of the areca nut slices. This facilitates the removal of the kernel from the inner cavity of the areca nut slices in subsequent production. The cavity opening device reduces the possibility of crushing the fruit pulp fibers caused by the cylinder squeezing the fruit half in related technologies, lowers the risk of fruit half cracking, and improves the yield of fruit half products.

[0040] Example 2 This application also discloses a cavity-opening method for a material cavity-opening system, the method comprising: Step 1: Activate the horizontal straight module 22, which will move the vertical straight module 23 and the support frame 10 on the slide table of the horizontal straight module 22, and drive the support frame 10 to slide horizontally to the top of the areca nut slices. Step 2: Activate the vertical straight module 23, which will cause the support frame 10 on the slide of the vertical straight module 23 to descend. During the descent, the two needles 11 on the support frame 10 will pierce into the two areca nut pieces respectively. Step 3: Activate the vertical straight module 23 to drive the needles 11 and areca nut pieces on the support frame 10 to rise to the preset height; Step 4: Start the second drive motor, which drives the bidirectional lead screw 24 at the output end of the second drive motor to rotate. The rotation of the bidirectional lead screw 24 drives the two nuts to move in opposite directions along the length of the bidirectional lead screw 24. During the movement of the nuts, the slider 12 and the needle 11 move, causing the areca nut pieces on the needle 11 to move and separate the two areca nut pieces that were originally in a close-fitting state. Step 5: Start the two third drive motors respectively, drive the needles 11 at the output end of the two third drive motors to rotate, and rotate the areca nut pieces on the needles 11 to the preset placement posture by a preset distance in the preset direction. Step 6: Activate the horizontal straight module 22 and the vertical straight module 23 respectively, so that the needles 11 on the support frame 10 can move from the needle channel 28 between the two connecting rods 5 on the same connecting frame 4 to place the areca nut pieces on the connecting frame 4 located below. It should be noted that at this time, the two connecting frames 4 set opposite each other are in an open state, and the distance between the two connecting frames 4 is greater than the thickness of the areca nut pieces. Step 7: Start the first drive motor, drive the gear 14 at the output end of the first drive motor to rotate. The rotation of the gear 14 drives the first rack 15 and the second rack 16 to move relative to each other, so that the first moving frame 7 and the second moving frame 8 move relative to each other, and clamp the betel nut pieces between the two connecting frames 4. Step 8: Activate the vertical straight module 23, which will cause the support frame 10 on the slide of the vertical straight module 23 to rise, and the needle 11 will rise from the needle channel 28 between the two connecting rods 5 and detach from the areca nut slice. Step 9: Activate the horizontal linear module 22, which moves the vertical linear module 23 and support frame 10 on the slide of the horizontal linear module 22, thereby resetting the two needles 11 to their initial positions. Step 10: Activate the second drive unit, causing the push rod 9 at the output end of the second drive unit to extend and push the areca nut pieces against the four connecting rods 5, so that the four protrusions 6 are respectively embedded into the inner cavity of the fruit half; It should be noted that step 10 in this embodiment of the application can be performed simultaneously with any of steps 7, 8 and 9. Step 11: Start the first drive motor. The first moving frame 7 and the second moving frame 8 drive the protrusion 6 to move in opposite directions. During the movement, the protrusion 6 applies force to the inner cavity of the areca nut slice, opening the inner cavity of the areca nut slice and realizing the automatic opening of the areca nut slice.
