摘要
为了满足生产中对方草捆打结器的实际需求,在分析方草捆打捆机使用的D型打结器及食品包装打卡机结构和工作原理的基础上,将两者优点加以集成,设计了打卡装置,取代D型打结器的打结钳嘴及驱动机构,从而组成了新型卡扣式方草捆打结器。由原来D型打结器的打结动作变为挤压卡扣,为验证新型打结器的适用性,制作了打结器试验台,进行了卡扣挤压的力学试验。3种不同规格的的U型卡扣和聚乙烯捆绳正交试验结果表明,用506号U型卡扣捆扎直径为2.5 mm的聚丙烯捆绳,卡扣成结率达99%,捆绳锁紧率为100%。在整个试验过程中,送绳、夹绳、打卡和割绳等主要动作时间配合恰当,依序顺利完成,满足设计要求。研究结果为进一步优化结构、工作参数及生产考核提供参考。
Knotter is in the key position of the rectangular baler, and it＇s working quality is in direct relation to the job performance of the baler. D type knotter is now used more widely in the rectangular baler, and most of them used in domestic are imported from abroad. It is not only expensive but inconvenient in use and maintenance because of the complicated organization. Therefore, a new clip bale knotter was developed in order to develop independent intellectual property rights and meet the needs of the country. The paper was focused on analyzing the structures and working principles of D type knotter of rectangular baler and food packaging clipper machine to form a new kind of knotter. The main innovation of the new design was that the impacting clip action replaced the original knotting action of D type knotter through the U type clip punching device. To evaluate the knotter device, the architecture and working principles of the clip bale knotter were described and some experimental results of knotter applicability were verified. The clip bale knotter was composed of two parts. One part was based on the fan-shape dentate cam disc of D type knotter, for which the original knotter hook and corresponding meshing teeth of the fan-shape dentate cam disc were dismantled and the clipping rope and cutting rope organization were retained. The other part was added with U type clip punching device, U type clip feed mechanism and the driving machinery of punching. By designing U type clip punching device, driving mechanism of punching as well as U type clip feed mechanism, combining the calculation of the motion sketch of the cam swing rod mechanism, the integration of the clip bale knotter was finished. When the knotter worked, rope was sent to the above of the clipping rope disc by the sending rope needle powered by spindle, then the clipping rope disc was rotated to grip the rope, and the swing shaft of the knotter organization was made to swing by spindle cam through the deep-groove ball bearing.
