纸盒包装生产线粉尘运移规律研究

目的 研究全自动高速纸盒包装生产线上气流和粉尘的运移规律,从而提供合理的控尘方案.方法 利用Ansys Fluent软件对某制药厂纸盒生产线上气流与粉尘的运动进行仿真模拟,并与现场实测数据进行比较.结果 气流与粉尘的运移轨迹基本一致;在开盒工位,含尘气流互相掺杂,粉尘扩散范围广,落尘严重;在说明书堆叠工位,粉尘受阻碍回流大量散落在承载台表面;在合盒工位,粉尘易团聚落入机构内部;在纸盒料仓工位,部分粉尘因静电吸附在传送带上,未降落粉尘随气流进入开盒区域.结论 文中控尘方案在说明书和纸盒料仓工位设置了吸尘口,以减少粉尘的输出,在开盒工位处设置了吸尘口以阻断粉尘的运移,达到了有效的除尘和控尘效果.

Dust Movement Law of Carton Packaging Production Line

The work aims to study the movement law of airflow and dust diffusion on the fully automatic high-speed carton packaging production line, to provide a reasonable dust control plan. Ansys Fluent software was used to simulate the airflow and dust movement of a carton production line in a pharmaceutical factory and compare the simulation results with the actually measured data. The moving trajectory of airflow and the dust was basically the same. In the unpacking station, the airflow containing dust was mixed with each other and the dust spread in a wide range and fell seriously. In the manual stacking station, a large amount of dust was hindered and scattered on the carrying platform surface. In the box closing station, dust was easy to agglomerate and fall into the inside of the mechanism. In the carton bin station, part of the dust was collected on the conveyor belt by static electricity, and the undropped dust entered the box opening area with the airflow. In the dust control plan, dust suction ports are set in the manual and the carton bin station to reduce dust output. Dust suction port is also set in box opening station to block dust movement and effectively control dust and remove dust.
