目的 提高瓦楞纸板取样器的精度和效率。 方法 结合相关国家标准的规定， 设计了一种瓦楞纸板自动备样装置。 装置主要由箱体、工作台 、进样盘、进样盘横向限位条、旋转刀片 、电机轴、切样垫板、瓦楞纸板纵向限位件、触摸屏控制系统和安全防护罩等部件组成。 结果 切出的样本合格率高， 楞孔清晰， 无毛边及撕边现象， 楞边平行度高；工作效率高， 切出合格样品的速度达1500～ 1800个/小时；安全防护罩即开即停， 安全性高；旋转切削方式使得刀片耐用 ， 节省成本。 结论 该装置取样精度和效率高，具有很强的实用性。

Objective To improve the accuracy and efficiency of the transitional manual cutting machine for corrugated cardboard. Methods Combined with the requirements of relevant national standards, an automatic corrugated cardboard sampling device was designed, which was mainly composed of cabinet, workbench, sample plates, horizontal caging devices on sample plates, revolving blades, motor shafts, cutting boards, vertical caging devices for cardboards, touch screen control system and safety hood. Results The samples prepared with this device had high passing rate, with clear corrugated board holes and parallel board edges, and without burrs or torn edges. It has high efficiency and could prepare 1500～ 1800 qualified samples per hour. It also showed high safety since the revolving blades could be stopped immediately by the opening of safety hood, what is more, rotary cutting made the blades durable and with long service life, so it had low cost. Conclusion This automatic corrugated cardboard sampling device had high accuracy and efficiency. In a word, it had a high practicability.
