中文摘要:
      目的 为解决现有人工使用绳子对编织袋进行捆扎打结效率低、劳动强度大的问题,设计一种基于双套结的编织袋自动捆扎打结机。方法 根据手工打结的过程,将机械化成结划分为束口、打结、套绳、系紧、断绳等步骤。利用3个气爪与2个抱爪的夹持动作将袋口挤成束状,束口后滑轨带动袋子运输到打结工位,再通过电机和气缸来驱动特制的绳结扩大装置来完成旋转成结和扩大绳环,利用横向和竖向滑轨的组合运动将绳环套在袋口,套绳后从绳子的两端拉紧绳结即可实现编织袋自动捆扎打结,构建完成控制系统,并制作出实体样机后进行打结试验。结果 对样机的工作性能进行测试试验,捆扎打结机的打结成功率约为92%,平均打结时长约为28.1 s/个。结论 通过编织袋自动捆扎打结机的研发,能有效减少人力劳动,具有推广价值。
英文摘要:
      The work aims to design an automatic binding and knotting machine for woven bags based on double-knot, so as to solve the problems of low efficiency and high labor intensity in manual use of ropes to tie woven bags. According to the manual knotting process, the mechanical knotting process was divided into bunching, knotting, lassoing, fastening, cutting, and other steps. The machine squeezed the bag mouth into a bundle through the clamping action of three air claws and two holding claws. After bundled, the bag was transported to the knotting station by the sliding rail. The special knot expanding device was driven by the motor and the cylinder to complete the rotary knotting and expand the rope loop. The horizontal and vertical slides were combined to put the rope loop on the mouth of the bag, and the knot was pulled from both ends of the rope to complete the automatic binding and knotting of woven bag. Finally, the control system was constructed and the prototype was made for knotting test. The working performance of the prototype was tested and the successful knotting rate of the machine was about 92%, and the average knotting time was about 28.1 s/piece. The research and development of the automatic binding and knotting machine of woven bags can effectively reduce manual labor and have promotion value.
