[0002] Areca is an evergreen tree belonging to the Arecaceae family, Areca genus, in the order Principes, class Liliopsida. Its stem is erect, arborescent, more than 10 meters tall, up to 30 meters at most, with obvious annular leaf scars. It is monoecious, the inflorescence is much branched, the ovary is oblong, the fruit is oblong or ovoid, the seed is ovoid, and the flowering and fruiting period is from March to April.

One end of the spring shaft 407 is connected to the cutter shaft 406, and the other end is fixed on the cutter seat 408. The pre-tightening force of the spring can be adjusted according to the hardness of the workpiece or the material characteristics, ensuring that the cutter blade 409 maintains a stable contact pressure during cutting, avoiding path deviation caused by material deformation or tool wear, and thus performing profiling cutting on the betel nut pulp. After the betel nut is cut, since the betel nut kernel is not directly cut together, there will be a certain adhesion between the betel nut pulp and the betel nut kernel, making the appearance of the betel nut still intact when it is moved by the material taking mechanism 502.

[0052] The centering component includes a spacer sleeve 410, a centering shaft 411, a swing arm 412, a V-shaped torsion spring 413, and a clamping arm 414.

[0060] S2. Based on S1, the loading robot 201 works to drive the loading module 203 to move to the upper end of the sorting tray 212. The vacuum suction nozzle 205 sucks the betel nuts in the sorting tray 212. The loading robot 201 continues to rotate to the loading conveyor belt 206.

[0061] S3. Based on S2, the adjusting cylinder 209 extends to drive the loading module 203 and the vacuum suction nozzle 205 to rotate as a whole by a certain angle and obliquely place them into the placing mold 207, so that one end of the betel nut is wrapped inside the arc-shaped stopper 208.

[0062] S4. Based on S3, the loading module 203 continues to move forward to the centering component. After the clamping arms 414 center and straighten the betel nuts in the placing mold 207, they enter the blades 409 of the upper cutting blade assembly 402 and the lower cutting blade assembly 403, and perform profiling cutting on the betel nut pulp from the tip.

[0063] S5. Based on S4, the betel nuts after profiling cutting continue to move forward in the placing mold 207 to the material taking mechanism 502. The material taking module 506 extends, driving the material taking plate 507 to descend until the material taking jaws 509 contact the two short sides of the cut betel nuts. The material taking cylinder 508 operates, driving the material taking jaws 509 to clamp the two cut petals of the betel nut respectively.

[0064] S6. Based on S5, the linear module 501 drives the material taking module 506 to move forward by one position, so that the rear end of the betel nut is separated from the covering area of the arc-shaped stopper 208. The material taking module 506 retracts, driving the material taking jaws 509 to clamp and lift the betel nut.

[0065] S7. Based on S6, the linear module 501 continues to move forward, driving the material taking mechanism 502 to move above the support plate 504. The material taking module 506 extends, driving the betel nut on the material taking jaws 509 to descend to the support 505. The material taking cylinder 508 retracts, placing the betel nut on the support 505, and the material taking mechanism 502 returns to its original position.

[0066] S8. Based on S7, the linear module 501 drives the second mounting plate 517 to move backward above the support 505, placing the betel nut between the opposing seed-removing jaws 515. The cylinder holder 516 moves horizontally along the second mounting plate 517, causing the opposing seed-removing jaws 515 to enclose the betel nut on the support 505.

[0067] S9. Based on S8, the seed-removing cylinder 514 extends, and the seed-removing jaws 515 grip the two cut petals of the betel nut. The cylinder holder 516 continues to move horizontally along the second mounting plate 517, slightly separating the betel nut within the seed-removing jaws 515.

[0068] S10. Based on S9, the upper ejector pin assembly 510 and the lower ejector pin assembly 511 extend simultaneously and pierce into the betel nut core. The cylinder holder 516 continues to move until the opposing seed-removing jaws 515 fully separate the betel nut from the betel nut core.

[0069] S11. Based on S10, the linear guide drives the second mounting plate 517 to move forward to the industrial camera group 602 and stay for a moment. The industrial camera group 602 takes pictures and analyzes the betel nuts grasped by the seed-removing jaws 515. Meanwhile, the lower ejector pin assembly 511 continues to retract, causing the betel nut core to roll along the support plate 504.

[0070] S12. Based on S11, the second mounting plate 517 continues to move forward above the discharge rack 601. After being analyzed by the industrial camera group 602, the seed-removing jaws 515 that hold the successfully pitted areca nuts are released, causing the finished areca nuts to fall out along the finished product discharge port 608 for collection. After that, the discharge cylinder 606 extends to drive the flip plate 605 to flip. At this time, the seed-removing jaws 515 that hold the areca nuts that failed to be pitted are released, causing the unqualified areca nuts to fall out along the defective product discharge port 609 for collection.

[0071] The present invention integrates the entire process of feeding, positioning, cutting, sorting, etc., realizes continuous production of a single machine, and meets the requirements of large-scale production.
