【摘要】 针对烟支复合滤棒成型过程供料速度慢、兼容性差的问题，结合物料形状，设计一种高速鼓轮供料装置。采用Ansys Workbench软件对物料出料时的碰撞过程进行瞬态动力学仿真，分析供料能够达到的最高转速，获得不同转速下物料的等效应变和等效应力云图，以及物料在Y方向的速度和加速度变化曲线。为验证高速鼓轮供料装置的可靠性，在保证装置高速运转和稳定供料的前提下，搭建实验平台，确定最佳生产转速。结果表明，当转速达到50 r/min时，最大等效应力为134.5 MPa，超过材料的屈服强度120.6 MPa，最大速度和最大加速度分别为-1 222.5 mm/s和1 289 900 mm/s~2。当转速为38 r/min时，在连续生产过程中合格产品的实际生产速度为37件/秒，满足烟支复合滤棒成型过程的高速供料需求。研究为实现烟支复合滤棒成型过程中的高速稳定供料提供借鉴。更多还原

【Abstract】 To address the issues of low feeding speed and poor compatibility in the forming process of cigarette composite filter rods, a high-speed drum wheel feeding device was designed based on the material shape. Transient dynamics simulation of the collision process during material discharge was conducted using Ansys Workbench software to analyze the maximum achievable feeding speed. The equivalent strain and stress distribution under different rotational speeds, as well as the velocity and acceleration curves of the material along the Y-axis, were obtained. To verify the reliability of the high-speed drum wheel feeding device, an experimental platform was established under the premise of ensuring stable high-speed operation. The optimal production speed was determined. Results demonstrated that when the rotational speed reached 50 r/min, the maximum equivalent stress was 134.5 MPa, exceeding the material’s yield strength of 120.6 MPa, with maximum velocity and acceleration values of-1 222.5 mm/s and 1 289 900 mm/s~2, respectively. At a rotational speed of 38 r/min, the actual production rate of qualified products during continuous operation reached 37 pieces per second, meeting the high-speed feeding requirements for cigarette composite filter rod forming. This study provides a reference for achieving stable and efficient feeding in the forming process of cigarette composite filter rods.更多还原
