废旧书籍书嵴自动切除机设计 摘要 本设计涉及一种切割装置，尤其涉及废纸回收设备中的一种切纸机。由于我国废纸回收质量远低与发达国家的水平，因此我国废纸回收率仅达到37.19% ,仍低于47.17%的世界平均水平和发达国家70%左右的水平。废纸中的杂质特别是书刊装订处的胶粘物、金属物，不但对产品内在质量、外观质量有决定性影响，而且给生产过程造成无穷的后患。 为提高回收废纸的质量，对书刊装订处的胶粘物、金属物进行处理，本次主要针对书背处的书胶进行切割的设计。切纸机主要由支撑台架、传动机构、夹紧传动机构、切割系统组成。传动机构采取圆盘转动带动书本转动，夹紧机构用了六个夹紧模块进行夹紧，切割系统使用了锯齿进行切割，效率快。 通过此次设计，我们成功的设计出了书本切胶机，大大提高了废纸回收厂的工作效率，解放了更多的劳动力，对社会发展有重要意义。 关键词：切纸机；废纸回收；书胶；夹紧；切割； ABSTRACT The utility model relates to a cutti
