A Dynamic model of cutting cluster motion in carrot peeling machine

Carrot peeling machines incorporating multi-blade mechanisms arranged along a circular arc have been developed globally to meet growing market demands through high operational throughput. This study presents a comprehensive analysis of the motion trajectory and force interactions of the main cutting assembly in an industrial-scale carrot peeling machine. A mathematical model of the peeling process is established using key design and physical parameters, including component geometry, frictional characteristics of mechanical joints, material properties, carrot morphology, and the required peeling force. The model facilitates prediction of the return time of the cutting blades to their initial position, with the derived time-response diagram correlating to the dynamic cycle of the peeling operation. The model not only accurately captures the oscillatory behavior of the cutting unit but also supports flexible parameter adjustment to accommodate the diverse size and shape variations of carrots in domestic agricultural production. This work constitutes a pivotal advancement toward the localization of peeling technology, addressing the economic constraints posed by high-cost imported machinery. The study provides a solid scientific basis for domestic equipment manufacturers to design, simulate, and optimize peeling systems, ultimately improving production efficiency and reducing investment costs. Additionally, the developed model forms the foundation for future research focused on productivity optimization of the cutting assembly.Currently, carrot peeling machines employing a multi-blade mechanism arranged in a circular arc have been designed and developed by various countries worldwide to meet the high demand of the market. Throughout this paper, the focus will be on analyzing the trajectory and the forces exerted by the primary cutting assembly in industrial carrot peeling machines. Before evaluation, the process of the peeling component will be mathematically modeled based on parameters such as: dimensions, friction, material properties and the peeling force. Consequently, based on the mathematical model with initial design parameters, the paper uncovered the graph of returning time in the peeling component. The resulting time gap aligns with the response cycle during the carrot peeling process. This study has established a foundation for optimizing the productivity calculation of the peeling component.
