HCF-M装盘机转角输送段链传动系统的改进

Improvement of chain drive system at turning section in HCF-M tray loader

为解决HCF-M装盘机转角输送段链传动系统链条易卡死、导轮易磨损等问题,采用组合式双联链轮技术对链传动系统进行了改进。通过修改电机参数将驱动电机换向,使主传动链条链节数缩短196节,主传动链条长度缩短1.9 m;在不改变链传动系统各从动轴同步关系的前提下,将单链轮改进为组合式双联链轮,使反向传动链轮数减少2个,链条导轮数减少5个,降低了因链条磨损造成的累计误差。以长沙卷烟厂生产的"白沙(精品)"牌卷烟为对象进行测试,结果表明:改进后HCF-M装盘机链传动系统一年内故障次数减少4.7次/台,维修时间缩短346.5 min/台。该技术可为提高烟支贮存输送系统运行稳定性提供支持。

As a solution to the frequent chain blockage in chain drive system and frequent guide wheel replacement at turning section of HCF-M tray loader, the chain drive system was upgraded. The drive motor was reversed via changing motor parameters, the main drive chains reduced by 196 links, 1.9 meters in length. While keeping the synchronous relation between driven shafts unchanged, a combined double sprocket system was designed to replace single sprocket. The new system dispensed with two reverse drive sprockets and five chain guide wheels, and decreased the cumulative error caused by chain wear. The cigarettes of brand"Baisha(Prime)"were tested in Changsha Cigarette Factory, and the results showed that the number of failures of HCF-M tray loader due to chain drive system reduced by 4.7 times within 12 months, the average maintenance time shortened by 346.5 min/machine. This technology provides a support for promoting the running stability of cigarette storing and conveying system.
