Shell centering ring cutting mechanism

Abstract

An upper cutter assembly and a lower cutter assembly which can be in contact are arranged at the upper end and the lower end of a cutter rest assembly in a mirror image mode, centering assemblies are arranged on one side of the upper cutter assembly at intervals, and the lower ends of the centering assemblies are close to the connecting position of the upper cutter assembly and the lower cutter assembly. In the production process of areca nuts, when the areca nuts need to be cut, the areca nuts firstly pass through the clamping arms, due to the fact that the V-shaped torsional spring at the upper end of the centering shaft and the swing arms meshed with the V-shaped torsional spring, the V-shaped torsional spring keeps uniform stress, meanwhile, the clamping arms can automatically adjust the areca nuts to be centered, and the precision of half-and-half cutting is improved.

Description

Technical Field

[0001] This utility model relates to the field of areca nut production technology, specifically to a circumferential cutting mechanism for fruit shells. 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] As the areca nut industry expands and food safety regulations impose higher requirements on the hygiene standards of areca nut processing, the demand for automated, high-precision sorting is becoming increasingly urgent. During areca nut processing, the areca nut shell needs to be cut in half for subsequent processes such as curdling. Existing areca nut cutting devices are typically standalone units with high maintenance costs, cannot be integrated with other automated production lines, and require periodic shutdowns for calibration, affecting the continuity of automated production.

[0004] Therefore, designing a circumferential cutting mechanism for areca nut shells that can improve the efficiency of centering and cutting areca nut shells while being compatible with more automated equipment has become a direction for further improvement. Utility Model Content

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. A centering component is spaced apart on one side of the upper cutting tool assembly. The lower end of the centering component is close to the connection between the upper cutting tool assembly and the lower cutting tool assembly.

Due to the V-shaped torsion spring at the upper end of the central shaft and the interlocking swing arms, the V-shaped torsion spring maintains uniform force while automatically adjusting the areca nut between the clamping arms to center it, improving the accuracy of the halving cut. One end of the spring shaft is connected to the cutter shaft, and the other end is fixed to the cutter holder. The preload of the spring can be adjusted according to the hardness of the workpiece or the material properties to ensure that the blade maintains a stable contact pressure during cutting, avoiding path deviation caused by material deformation or cutter wear, thereby performing contour cutting of the areca nut pulp.
