Description

Technical Field

[0001] This utility model relates to the technical field of areca nut processing equipment, specifically to a novel automatic areca nut pitting device. Background Technology

[0002] In the current areca nut production process, pitting is an essential step. Most areca nut manufacturers currently use either manual or automated pitting methods. Manual pitting is inefficient and labor-intensive, and the contact between hands and the areca nut during manual pitting can cause contamination. While automated pitting can replace manual labor and improve efficiency, it also has drawbacks. Firstly, the existing pitting equipment is complex and difficult to maintain. Secondly, it can easily damage the areca nuts during pitting, leading to some being downgraded or even rendered unusable, thus reducing the yield.

[0003] Therefore, in order to improve the efficiency of pitting betel nut products during the production process, developing a new type of automatic pitting device for betel nuts has become a direction for further improvement. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a novel automatic areca nut pitting device, including a fixed plate fixedly installed on an automatic areca nut production line. The device is characterized by further including a connecting plate, a support assembly, a cylinder, a connecting plate, a sliding assembly, and a pit-binding assembly. The fixed plate has a connecting plate at its rear end, and a support assembly at its upper end. A cylinder is fixedly installed at the lower end of the fixed plate, and the output end of the cylinder is connected to the connecting plate for transmission. The connecting plate is respectively provided with a sliding assembly and a pit-binding assembly.

[0005] Preferably, the core-piercing assembly includes a needle, a fixing seat, and a core-blocking plate. The sliding assembly is provided with a fixing seat that is relatively inclined inward. The lower end of the fixing seat is provided with a needle, and the end of the needle passes through the core-blocking plate.

[0006] Preferably, the sliding assembly includes a guide rail, a connecting rod, and an adjusting plate. The adjusting plate is fixedly mounted on the front end of the fixed plate, and the guide rail is provided on the adjusting plate. The fixed seat is slidably connected to the guide rail, and the upper end of the fixed seat is connected to the connecting plate via a connecting rod.

[0007] Preferably, the support assembly includes a bearing seat plate, a linear bearing, a guide rod, a spring, and a support plate. The upper end of the connecting plate is provided with a bearing seat plate, and the bearing seat plate is provided with linear bearings arranged in parallel. The guide rod passes through the linear bearing, and the guide rod is sleeved with a spring. The upper ends of the spring and the guide rod abut against the support plate, and the lower end of the spring abuts against the outer periphery of the linear bearing.

[0008] Preferably, the sealing cover on the fixing plate is provided with a cap.

[0009] Preferably, the core-blocking plate has a slot, through which the needle can pass without contacting the core.

[0010] Preferably, the needles are four needles arranged in a relatively staggered manner.

[0011] Compared with the prior art, the present invention has the following beneficial effects: (1) This utility model has a connecting plate at the rear end of a fixed plate, and a support component at the upper end of the connecting plate; a cylinder is fixed at the lower end of the fixed plate, and the output end of the cylinder is connected to the connecting plate for transmission. A sliding component and a pitting component are respectively provided on the connecting plate. A fixed seat with a relatively inward tilt is provided on the sliding component, and a pitting needle is provided at the lower end of the fixed seat. The end of the pitting needle passes through the pit-blocking plate. When the cylinder pushes the connecting plate downward, the connecting rod drives the fixed seat to slide inward along the guide rail, so that the pitting needle pierces the areca nut at an inclined angle and completes the pitting, improving the pitting stability. The spring in the support component cooperates with the linear bearing to buffer vibration and ensure accurate positioning of the pitting needle, improving the stability of the equipment and the yield. In addition, the groove design on the pit-blocking plate allows the pitting needle to pass smoothly and avoids the accumulation of residual fruit scraps. The four staggered pitting needles further improve the pitting efficiency and adaptability. Combined with the sealing structure, it effectively reduces dust pollution and ensures a clean production environment. The whole set of devices is compact in structure and runs smoothly, significantly improving the automation level and processing quality of areca nut pitting and increasing the yield of pitted products. This device demonstrates excellent maintainability and adaptability in practical applications. The staggered arrangement of the four needles effectively distributes force, reduces the risk of jamming, and extends the service life of core components. The precise coordination between the guide rail and linkage transmission, combined with cylinder stroke control, enables accurate adjustment of the needle feed depth, making it suitable for stable pitting operations on areca nuts of different sizes. The spring preload design maintains constant pressure on the support plate under dynamic loads, further enhancing the system's impact resistance. The overall structure facilitates disassembly and cleaning, and the coordinated sealing of the cap and pit-blocking plate effectively prevents juice leakage, meeting food processing safety standards and making it suitable for large-scale promotion and use.
