摘要:: 当前导爆药下药工艺普遍依靠药剂自重完成，存在管体药剂分布不均、爆速波动较大的问题。针对此问题，设计了依靠下药游标精确控制下药量的一种新型下药系统。下药游标采用变频电机驱动，设计了定容药槽,可根据不同的拉制速度调整游标转速，精确且方便地控制下药量；另通过一种新的检测方法(失重法)，实时测量导爆管每米的药量，从而提高导爆管质量。

Abstract:: Current powder dosing system of detonating tube generally relies on the gravity of powder, which may cause uneven distribution of the powder and the resultant large fluctuation of detonation velocity. A new powder dosing system was proposed based on drugging cursor to precisely control the amount of powder. The cursor was driven by variable frequency motor and the drug slot was designed as with a constant volume. Cursor rotating speed could be adjusted according to the production speed to achieve a precise and easy control over the amount of powder. A new testing method, weight loss measurement, was applied for the real-time dosage measurement and thereby the quality improvement of detonating tube.
