箱装烟梗自动翻箱倒料系统的设计

Design of automatic stem case tipping and tilting system

为解决箱装烟梗人工投料过程中劳动强度大、烟梗漏料多及塑料袋碎片污染烟梗等问题,设计了一种箱装烟梗自动翻箱倒料系统。该系统由辊道输送机、网格式振动格栅、翻箱倒料机以及纸箱折叠回收机组成。翻箱倒料机包括旋转底座、升降装置和夹抱装置,可以模拟人工倒料过程,通过将烟梗箱旋转180°后实现翻箱倒料;在倒料过程中不需切割塑料内衬袋,避免形成塑料袋碎片。以龙岩烟草工业有限责任公司烟梗开包倒料生产线为对象进行测试,结果表明:使用自动翻箱倒料系统后,平均生产时间由101 min/批次降低至52 min/批次,烟梗损失量减少97.2%,塑料袋碎片数量由3.1个/批次降低至0。该技术可为提高梗丝设备生产效率提供支持。

To mechanize the stem feeding process,minimize stem waste,and avoid broken plastic pieces contamination,an automatic stem case tipping and tilting system was designed.The system mainly consists of a roller conveyor,a grid-type shaker,a stem case tipping and tilting machine,and a case reclaimer.The case tipping and tilting machine is composed of a rotatable base,an elevator and a clamping device,it simulates the manual operation to complete case tipping and tilting.There is no need to cut the plastic bag during the tilting process,thus avoiding the generation of broken plastic pieces.The designed system was tested on the tobacco stem feeding line in Longyan Tobacco Industrial Corporation Limited.The results showed that the automatic case tipping and tilting system reduced the average production time from 101 to 52 min/batch,reduced stem waste by 97.2%and the number of broken plastic pieces from 3.1 pieces/batch to 0.This technology supports the promotion of production efficiency of stem processing.
