纸盒高度变化对开盒成型装置的影响

为提高全自动装盒机对不同尺寸纸盒的适应性，分析纸盒高度变化对盒坯料仓中盒坯位置和取盒机构中吸盘轨迹的影响，并推导出在吸盘吸取纸盒基准位置不变的前提下，盒坯料仓的位置调整规律。以常用的螺纹传动与位置指示器相结合的位置调整方式为例，给出了齿节和导程的选取方法，以及实际设计中可能存在的调整偏差的消除方法。理论分析和实际测试表明，较小的调整偏差不会显著影响成盒装置的正常工作，可不必采取措施将其完全消除。

The Effects of Carton Height Changes on the Carton Opening and Forming Device

In order to improve the adaptability of the automatic cartoning machine to different sizes of cartons, the effects of carton height change on the position of the carton blank in the carton magazine and the trajectory of the suction cup in the box picking mechanism were analyzed, and the position adjustment principle of the carton blank magazine was derived under the premise that the reference position of the carton sucked by the suction cup remained unchanged. Taking the position adjustment method of combining the commonly used thread transmission and position indicator as an example, the selection method of tooth joint and lead was given, and the elimination method of adjustment deviation that might exist in the actual design was given. Theoretical analysis and practical tests showed that small adjustment deviations did not significantly affect the normal operation of the boxing unit, and it was not necessary to take measures to completely eliminate it.
