摘要:
为解决当前空腔粉末填充装置工作效率不高、填料速度较慢以及出口容易堵塞的问题，对我国专利数据库中的空腔粉末填料装置专利进行了检索和分析。首先，运用因果分析法分析了现有空腔粉末填料装置的不足之处; 接着，采用小人法获取解决问题的理论模型; 然后，基于TRIZ理论的40个发明原理以及39个通用工程参数对原模型的技术矛盾进行分析; 最终创新设计了一种空腔粉末填料装置。该设计可以提高粉末填料的填充速度，以及填充的可靠性。
Abstract:In order to solve the problems that the devices of filling powder into cavity have a low efficiency and a slow filling speed, and the outlet is easily blocked, the patents of devices of filling powder into cavity in our patent database have been searched and analyzed. Firstly, the existing devices have been analyzed using causality analysis method. Then, the algorithm of the method of the small people is used to obtain the theoretical model to solve the problem. After that, the technical contradictions of the original model have been analyzed by 40 invention principles and 39 general engineering parameters of TRIZ theory. Finally, an innovative device of filling powder into cavity has been designed. The design can improve the filling speed and reliability of powder filler.
