| 中文摘要: |
| 为解决柜式喂料机电子秤这一定量喂料系统频繁堵料问题，通过对设备结构及控制匹配进行研究，分析了堵料
原因。堵料主要发生在尾料阶段的柜式喂料机出口处，这是由松料辊反转导致出料的楔形空间过小所致；爬坡输送带与
计量管间的落料口处堵料，这是由计量管料位光电管与喂料机底带和爬坡带的匹配不当，以及高料位光电管与落料缩口
间的缓冲空间不足导致。通过重新调整松料辊轴承座位置、设定新的喂料机底带、爬坡带调速模型，以及调整高料位光
电管位置等方法进行了改进。应用效果表明，改进后定量喂料系统较好地解决了堵料问题，堵料频次由原来的18.7次／
月减少到0.3次／月，保证了物料流量稳定性。 |

| ln order to solve the frequent tobacco blocking problems of the quantitative feeding system, the reasons for
electronic scale tobacco blocking were analyzed by studying the equipment structure and control matching. Tobacco
blocking mainly occurred at the outlet of the cabinet feeder in the tailing stage, which was caused by a small wedge-
shaped tobacco discharge space formed by the reverse rotation of the tobacco- releasing rollers; and in addition. tobacco
blocking occurred at the blanking outlet between climbing conveyer belt and metering tube were caused by the improper
matching between the tobacco level photocells at the metering tube, and the bottom belt of the feeder and the climbing
conveyer belt; as well as the insufficient buffer space between the high tobacco level photocell and the blanking necking
portion. Improvements have been made by readjusting the position of bearing pedestal of tobacco-releasing rollers,
setting a new speed regulation model for the bottom belt of feeder and climbing conveyer belt. and adjusting the position
of the high tobacco level photocell, etc. The application effect shows that tobacco blocking problem can be well solved
by improved quantitative feeding system; tobacco blocking frequency is reduced from the original 18. 7 times/month to
0. 3 times/month. and the stability of material flow can be ensured. |
