粉粒及块状物料包装流水线自动封口机设计

摘要

针对粉粒及块状物料的大容量包装流水线中灌装至封口环节普遍存在一定脱节,需要人工全程干预,存在劳动强度大、生产效率较低等现状,设计了粉粒及块状物料包装流水线自动封口机.自动封口机的压紧部分采用双边驱动的平行四边形连杆机构,实现包装袋袋口热封后的密合;通过对进料口、封口、出料及调姿部分的机械结构设计,配合以STM32芯片作为自动控制的核心,辅以各相关传感器的信号采集与处理,实现粉粒及块状物料包装流水线自灌装到封口流程的全程自动化运行.通过对关键部件的静力学与运动学仿真分析及核心机构的试制与调试,验证了所设计设备具有良好的运行稳定性与可靠性.该设计能够降低劳动成本,提高生产效率.%A certain disjunction exists in the process from filling to sealing of large packets′silt and dump material packaging line, with high labor intensity, low efficiency and whole course artificial intervention.A self-adaptive sealing machine for silt and dump material packaging line was designed to solve the above problems.The packaging bag's lura successfully sealed up after being heated seal by using a double-sided driving parallelogram mechanism in the part of lura pressing section.By coordinating the mechanical structure design in inlet part, sealing part, discharge part and posture alignment part with the using of STM32 chip which served as the core of control system and responsible for collecting and analyzing information from the sensor all around the machine, the automatic operation was realized for the filling to sealing of large packets'silt and dump material packaging line.The sealing machine had been proved to have a good running stability and reliability by kinematics and statics simulation with prototype trial and commissioning for key parts. The process in silt and dump material packaging line from filling to sealing can reduce labor cost and improve production efficiency.
