Synergistic Tile Fragmentation Mechanism of Toothed Cylinder on Ceramic Tile Calibrating Machine

为了研究刮平机滚齿破碎瓷砖机理,分析刮平机的结构和运行原理,提出滚筒滚齿协同冲击破碎瓷砖,并分析其机理。建立了单滚齿冲击破碎瓷砖和多滚齿协同破碎瓷砖的模型,通过SEM实验验证了所建模型的正确性,同时验证了多滚齿协同冲击破碎瓷砖机理理论符合瓷砖表面形貌。实验还得出:中刮、精刮前瓷砖旋转90°有助于滚齿协同破碎效应的发挥,滚齿协同破碎效应主要体现在中、精刮工序中。

In order to investigate the tile fragmentation mechanism of the toothed cylinder on it, the structure and principle of calibrating machine were analyzed. Mathematical models for impact crushing by single tooth and synergistic fragmentation by multi-teeth were established respectively. SEM was used to observe ceramic tile morphologies after rough calibrating, semi finish calibrating and finish calibrating. The results verified the effectiveness of the models and the agreement between the theories of the synergistic tile fragmentation by multi-teeth and the observed surface morphologies of the ceramic tiles calibrated in different stages. It＇s also showed that rotating the tile 90 degrees counterclockwise before semi finish calibrating and finish calibrating could improve the result of synergistic fragmentation by multiteeth in these two stages where the action mainly occurred.
