Abstract
The convex curved chute device is commonly used for the attitude transformation of lightweight rod materials. However, the current design of the chute curve for these materials lacks theoretical guidance, and its quality cannot be quantitatively assessed, leading to issues such as material blockage and damage. The work aims to propose a method for the quantitative evaluation and optimization of convex curved chutes through dynamic analysis and numerical simulation, so as to provide a solid reference for the design and optimization of such chutes. With cigarette rods, a typical lightweight rod material, as the research object, a dynamic model of the material and chute system was established with ADAMS simulation software. The key factors influencing the material behavior were analyzed. The dynamic motion of the material along the convex curved chute was studied, and based on these key factors, an evaluation and optimization method was developed. The optimized chute curve successfully addressed the issue of the material flying off the chute before reaching the vertical baffle. The departure angle of the material increased from 64.70° to 70.20°, and the theoretical value of the evaluation index improved from 0.97 to 1.45. These evaluation results aligned closely with both simulation and experimental outcomes, demonstrating a consistent trend. In conclusion, the proposed method for quantitative evaluation and optimization of convex curved chutes offers significant improvements. The optimized curve reduces material damage and minimizes the risk of blockage compared to the original design. Both simulation and physical testing validate the effectiveness of the proposed evaluation method, confirming its applicability in real-world scenarios.
