FT6B型切片机导料装置的改进

Improvement of the Feeding Device of the FT6B Slicer

摘要: 切片机是制丝生产工艺中的一台重要设备，其主要工艺任务是对醇化、拆包后的烟包切块，以便于烟叶的松散、回潮均匀，为后序生产做准备。在膨胀烟丝车间使用该设备的过程中，导料装置联接螺栓经常出现断裂，在寻找原因的过程中，对原导料装置的横档进行力学分析后，找到了导致螺栓断裂的原因是原装置存在设计缺陷，联接螺栓在工作时受到较大的剪切力。针对这个问题，制定了两个解决方案，一个是增加联接螺栓的强度，但更换后的螺栓也被剪断；另一个是重新设计横档结构，从而改变横档的受力方式。经过实际应用，改造效果良好，彻底解决了设备存在的问题。

Abstract: The slicer is an important piece of equipment in the tobacco processing industry. Its main task is to slice the mellowed and unpacked tobacco leaves into pieces to facilitate loosening and uniform rehydration of the tobacco leaves, preparing them for subsequent production. During the use of this equipment in the expanded tobacco workshop, the connecting bolts of the feeding device frequently broke. In the process of finding the cause, a mechanical analysis of the crossbar of the original feeding device revealed that the bolt breakage was due to a design flaw in the original device, where the connecting bolts were subjected to excessive shearing force during operation. Two solutions were developed to address this problem: one was to increase the strength of the connecting bolts, but the replaced bolts also broke; the other was to redesign the crossbar structure, thereby changing the stress distribution on the crossbar. After practical application, the modification achieved good results and completely solved the equipment problem.
