Description

Technical Field

[0001] This utility model relates to the field of areca nut production technology, specifically to an automatic areca nut seed cutting and core removal machine. Background Technology

[0002] Areca nut is an evergreen tree belonging to the class Monocotyledonous plants, order Primary order, family Arecaceae, and genus Areca. It has an erect, tree-like stem that can grow to over 10 meters tall, with some reaching up to 30 meters. It has distinct annular leaf scars, is monoecious, and has multi-branched inflorescences. The ovary is oblong, the fruit is oblong or ovoid, and the seeds are ovoid. It flowers and fruits from March to April.

[0003] Areca nut processing requires the removal of pits and seeds to improve safety and taste. Traditional manual seed cutting is inefficient, costly, and prone to problems such as missed cuts and over-cutting. With the expansion of the areca nut industry and the increasing demands for hygiene standards in areca nut processing according to food safety regulations, the need for automated, high-precision sorting is becoming increasingly urgent. Existing areca nut seed cutting equipment, which mostly relies on manual feeding or simple mechanical positioning, is prone to cutting deviations due to the irregular shape of the areca nuts (such as bending or uneven surfaces), resulting in pit residue or damaged pulp, and incurring high maintenance costs.

[0004] Therefore, designing an automatic betel nut cutting and core removal machine that can achieve continuous production while precisely positioning and cutting has become a direction for further improvement. Utility Model Content

[0016] (2) The present invention has a tool holder assembly fixed on the frame. The upper and lower ends of the tool holder assembly are mirror images of an accessible upper cutting tool assembly and a lower cutting tool assembly.

The middle part of the feeding module 203 is provided with an angle adjustment mechanism, which is used to adjust the working angle of the feeding module 203 and the vacuum nozzle 205.

[0036] The angle adjustment mechanism includes an adjusting cylinder 209, a linkage shaft 210, and a clamping plate 211. The adjusting cylinder 209 is fixedly mounted on the inner side of the feeding plate 202. The output end of the adjusting cylinder 209 is connected to the linkage shaft 210 for transmission. The linkage shaft 210 is fixedly connected to the clamping plate 211, and the lower end of the clamping plate 211 is fixedly connected to the feeding module 203. Through the angle adjustment mechanism, the feeding module 203 can accommodate workpieces of different shapes, sizes, or tilt angles using the same mold, reducing the frequency and cost of changing the feeding module 203. Furthermore, for asymmetrical or tilted workpieces such as trapezoidal or arc-shaped parts, the angle adjustment mechanism can directly correct the forming angle of the feeding module 203 without redesigning complex structures, shortening the trial molding cycle, and enabling rapid angle switching during continuous production, reducing downtime and meeting the needs of modern intelligent production, thus improving work efficiency.

[0037] The frame 1 is equipped with a recirculating feeding conveyor belt 206, on which are evenly distributed placement molds 207. Gaps are left between adjacent placement molds 207 to facilitate the passage of the cutter. An arc-shaped stop 208 is integrally formed on the upper rear side of each placement mold 207. The vertical length of the arc-shaped stop 208 is less than 1 / 3 of the length of the placement mold 207. The arc-shaped stop 208 physically restricts the movement range of the areca nuts within the placement mold 207, effectively preventing the areca nuts from shifting and detaching during the cutting process. This also facilitates overall maintenance and adjustment.

[0038] The cutting device 4 includes a blade holder assembly 401, an upper cutting blade assembly 402, a lower cutting blade assembly 403, and a centering component.

One end of the spring shaft 407 is connected to the cutter shaft 406, and the other end is fixed to the cutter holder 408. The preload of the spring can be adjusted according to the hardness of the workpiece or the material properties to ensure that the blade 409 maintains a stable contact pressure during cutting, avoiding path deviation caused by material deformation or tool wear, thereby performing contour cutting of the areca nut pulp. After the areca nut is cut, the areca kernel is not cut off along with it. The areca nut pulp and the areca kernel will adhere to each other to a certain extent, so that the areca nut still looks like a whole piece when it is moved by the material handling mechanism 502.

[0039] The centering assembly includes a spacer 410, a centering shaft 411, a swing arm 412, a V-shaped torsion spring 413, and a clamping arm 414.

[0045] The method for automatically cutting and removing the core from areca nuts, applied to an automatic areca nut cutting and core removing machine, includes the following steps:

[0046] S1. The industrial control box 7 is opened, putting all components into standby mode. The elevator 3 gradually rolls the areca nuts into the material handling tray 212 through vibration screening.

[0047] S2. Based on S1, the loading robot 201 drives the loading module 203 to move to the upper end of the sorting tray 212. The vacuum nozzle 205 sucks up the areca nuts in the sorting tray 212. The loading robot 201 continues to rotate onto the loading conveyor belt 206.

[0048] S3. Based on S2, adjust the extension of the cylinder 209 to drive the feeding module 203 and vacuum nozzle 205 to rotate at a certain angle and be placed obliquely into the placement mold 207, so that one end of the areca nut is wrapped inside the arc-shaped block 208.

[0049] S4. Based on S3, the feeding module 203 continues to move forward to the centering component. The clamping arm 414 centers and straightens the areca nuts in the placement mold 207 and then enters the blades 409 of the upper cutter component 402 and the lower cutter component 403 to perform contour cutting of the areca nut pulp from the tip.

[0050] S5. Based on S4, the areca nut after contour cutting continues to advance in the placement mold 207 to the material picking mechanism 502. The material picking module 506 extends and drives the material picking plate 507 to descend until the material picking claw 509 contacts the two short sides of the cut areca nut. The material picking cylinder 508 works to drive the material picking claw 509 to clamp the two cut segments of the areca nut respectively.

[0051] S6. Based on S5, the linear module 501 drives the material picking module 506 forward one position, so that the rear end of the betel nut is removed from the coverage area of ​​the arc-shaped stop 208. The material picking module 506 retracts, driving the material picking claw 509 to clamp the betel nut and lift it up.

[0052] S7. Based on S6, the linear module 501 continues to move forward, driving the material picking mechanism 502 to move above the tray 504. The material picking module 506 extends, driving the areca nuts on the material picking claw 509 to descend to the bracket 505. The material picking cylinder 508 retracts, so that the areca nuts are placed on the bracket 505. The material picking mechanism 502 returns to its original position.

[0053] S8. Based on S7, the linear module 501 drives the second mounting plate 517 to move backward to above the bracket 505, so that the areca nut is placed between the opposite deseeding claws 515. The cylinder frame 516 moves laterally along the second mounting plate 517, so that the opposite deseeding claws 515 cover the areca nut on the bracket 505.

[0054] S9. Based on S8, the deseeding cylinder 514 extends, the deseeding gripper 515 grasps the two halves of the betel nut that have been cut, and the cylinder frame 516 continues to move laterally along the second mounting plate 517, slightly pulling apart the betel nut inside the deseeding gripper 515.

[0055] S10, based on S9, the upper ejector assembly 510 and the lower ejector assembly 511 extend simultaneously and insert into the areca nut kernel. The cylinder frame 516 continues to move until the relative seed-removing claws 515 completely pull the areca nut apart from the areca nut kernel.

[0056] S11. Based on S10, the linear guide rail drives the second mounting plate 517 to move forward and stop at the industrial camera group 602. The industrial camera group 602 takes pictures and analyzes the areca nuts gripped by the deseeding claw 515. At the same time, the lower ejector pin assembly 511 continues to retract, causing the areca nuts to roll down along the tray 504.

[0057] S12. Based on S11, the second mounting plate 517 continues to move forward to above the discharge rack 601. After analysis by the industrial camera group 602, the deseeding claw 515 that clamps the successfully deseeded areca nuts is released, allowing the finished areca nuts to fall out along the finished product discharge port 608 for collection. Then, the discharge cylinder 606 extends to drive the flipping plate 605 to flip. At this time, the deseeding claw 515 that clamps the undeseeded areca nuts is released, allowing the unqualified areca nuts to fall out along the defective product discharge port 609 for collection.
