电子秤自动堵料装置的设计与应用

Design and Application of an Automatic Material Blocking Device for Electronic Scales

摘要: 制丝生产线薄片添加工序中，电子秤运输带末端薄片受震动和气流影响易发生掉落，影响生产环境并存在安全隐患。针对该问题，设计了基于曲柄摇杆机构的自动堵料装置，采用气缸驱动挡板与电子秤运输带同步动作。当运输带停止时，挡板关闭封堵末端；当运输带启动时，挡板打开恢复物料流动。装置主要由气缸、曲柄与摆动轴以及挡板等关键部件组成，通过机械传动实现精确控制。应用结果表明，装置彻底解决了薄片掉落问题，显著改善了生产环境，消除了安全隐患，提升了生产连续性和设备可靠性，为制丝生产线技术改进提供了有效方案。

Abstract: In the tobacco shred production line during the sheet addition process, sheets at the end of the electronic scale conveyor belt are prone to falling due to vibration and airflow effects, which affects the production environment and poses safety hazards. To address this problem, an automatic material blocking device based on a crank-rocker mechanism was designed, using pneumatic cylinders to drive baffles in synchronous operation with the electronic scale conveyor belt. When the conveyor belt stops, the baffle closes to block the end; when the conveyor belt starts, the baffle opens to restore material flow. The device mainly consists of key components, including pneumatic cylinders, cranks, swing shafts, and baffles, achieving precise control through mechanical transmission. Application results show that the device completely solves the sheet falling problem, significantly improves the production environment, eliminates safety hazards, enhances production continuity and equipment reliability, and provides an effective solution for the technical improvement of tobacco shred production lines.
